20160133409 | METHOD OF MANUFACTURING DIAPHRAGM WITH CONTACT, AND PRESSURE SWITCH INCLUDING DIAPHRAGM WITH CONTACT MADE BY THE METHOD - In a method of manufacturing a diaphragm with a contact, contact stocks each forming a movable contact on a stock formed out of a strip-shaped thin metal sheet material, or a rolled material are bonded at predetermined intervals to the stock by resistance welding, for example to form a diaphragm stock with a contact. Next, the stock of a diaphragm with a contact is subjected to continuous blanking with a predetermined diameter from each movable contact as center to produce a diaphragm with a contact. | 05-12-2016 |
20160133408 | PRESSURE SWITCH - In a pressure switch including a diaphragm, when the diaphragm of the pressure switch is inverted, a cross-shaped contact face of a fixed contact comes into contact with an annular contact of the diaphragm at four positions. | 05-12-2016 |
20160131284 | SWAGING STRUCTURE - The present invention provides a swaging structure having a high pressure resistance strength suitable for a high pressure switch that solves the conventional disadvantages that the swaging for providing an increased thickness causes a manufacturing facility having a larger size or the swaged part having winkles or that a pressure switch finds a difficulty in the adjustment of the swaging margin when the number of diaphragms is changed for example. A swaging structure comprises at least a to-be-swaged member required to have airtightness to a surrounding environment and a swaging member configured to retain the to-be-swaged member by a swaging processing, the swaging member has an annular side wall surrounding the to-be-swaged member to retain the to-be-swaged member after the swaging processing and the swaging structure further includes an annular spacer including therein a penetration hole to be sandwiched between the to-be-swaged member and the annular side wall after the swaging processing. | 05-12-2016 |

20150059179 | STRUCTURE FIXING DIAPHRAGM TO DRIVE SHAFT AND METHOD FOR FIXING DIAPHRAGM TO DRIVE SHAFT - In an electromagnetic control valve configured to cancel out forces acting on a valve body by differential pressure using a diaphragm, pressure tightness and durability of the diaphragm are improved. A needle-shaped projection is formed on a lower end of a piston section of a valve rod that is a drive shaft. An insertion hole is formed in the center of a diaphragm guide. The center of the diaphragm is stuck on the needle-shaped projection to make it pass through it. The needle-shaped projection is inserted into the insertion hole in the diaphragm guide. An end of the needle-shaped projection is spot-welded. The diaphragm is stuck with the needle-shaped projection to fix it to the valve rod without cutting a base fabric of the diagram. A needle-shaped projection may be formed on the diaphragm guide and an insertion hole may be formed in the valve rod. | 03-05-2015 |
20140220462 | FILTER DEVICE, CONTROL VALVE COMPRISING THE FILTER DEVICE, AND FUEL CELL SYSTEM | 08-07-2014 |
20140205480 | CENTRIFUGAL PUMP - A centrifugal pump includes a main body casing. The main body casing includes an upper main body casing, a lower main body casing fixed to the upper main body casing, and a blade casing. In the blade casing, an interior space S | 07-24-2014 |
20140069066 | FILTER DEVICE - A filter device disposed in a moist fluid passage of the fuel cell system includes a fluid introducing path which introduces a fluid that flows in the moist fluid passage, a filter to permeate the fluid introduced from the fluid introducing path and remove foreign matter in the fluid, a fluid discharge path which discharges a fluid that passed the filter, and a rotating driving mechanism, connected with the filter, that rotates the filter so that substances that adheres to the filter are removed by the centrifugal force. In the filter device, water does not adhere to and does not remain in the filter. When leaving the system under the low temperature after the system stops, blockage by freezing the filter can surely be prevented. The complex control and the heat source such as a heater for defrost is unnecessary. Thus, a cheap and compact filter device can be provided. | 03-13-2014 |
20130206851 | EXPANSION VALVE - There is provided an expansion valve which, by moving the sub-valve in a valve housing, controls the flow rate of a refrigerant in a first flow direction and releases the refrigerant to flow in a second flow direction, wherein the sub-valve is reduced in weight and a valve port is provided with high accuracy. The sub-valve includes a guide member formed by press work and a valve seat member formed by cutting. The sub-valve is seated on a sub-valve seat of a valve seat ring when the pressure in a main valve chamber is high, and is moved away from the sub-valve seat when the pressure in the main valve chamber is low. The sub-valve is reduced in weight by forming the guide member by press work, and the valve port is formed with improved accuracy by forming the valve seat member by cutting. | 08-15-2013 |

20110120161 | EXPANSION VALVE, HEAT PUMP TYPE REFRIGERATION CYCLE APPARATUS, AND AIR HANDLING UNIT - A first expansion valve is provided in an outdoor unit, and a second expansion valve is provided in an indoor unit. A pipe line connects a first joint pipe of the first expansion valve and a second joint pipe of the second expansion valve. When a refrigerant flows in from the second joint pipe and flows out from the first joint pipe, the first and second expansion valves are in a full open state due to pressure of the refrigerant. When the refrigerant flows in from the first joint pipe and flows out from the second joint pipe, the first and second expansion valves are in semi-closed state (flow rate controlling state). In a cooling mode, the second expansion valve expands the refrigerant just before an indoor heat exchanger, and in a heating mode, the first expansion valve expands the refrigerant just before an outdoor heat exchanger. In both heating and cooling mode, a large amount of refrigerant flows through the pipe line to reduce pressure loss. | 05-26-2011 |
