20080207366 | TENSIONER - To reduce seizing in a tensioner having a plunger slidable in a plunger-accommodating hole of a tensioner housing and biased in the projecting direction, the tensioner housing is formed of a hyper-eutectic Al—Si series alloy containing Si in the range from 14 to 16 weight % and having a particle diameter of proeutectic Si in the range from 20 to 30 μm. | 08-28-2008 |
20080220918 | Downward angle settable hydraulic tensioner - The hollow plunger of a hydraulic tensioner for an engine timing chain protrudes from a tensioner housing in an oblique downward direction. An inner sleeve fixed to the housing slidably protrudes into the interior of the plunger, and has a ball check valve at its protruding end. Oil is supplied though the sleeve and the check valve to a high pressure oil chamber formed inside the plunger, and flows outward through a two-part leakage path formed by a gap between the sleeve and the interior of the plunger and a gap between the exterior of the plunger and an interior wall of a plunger-accommodating hole in the housing. Any air that enters the tensioner accumulates in a region surrounding the upper end of the sleeve, rather than in the high oil pressure chamber inside the plunger. | 09-11-2008 |
20080261737 | Hydraulic tensioner - A check valve unit in a hydraulic tensioner comprises a check ball, a steel ball guide having an inner wall allowing a limited range of longitudinal movement of the ball but restricting its lateral movement, a steel retainer attached to the high pressure oil chamber side of the ball guide, and a steel ball seat attached to the oil supply side of the ball guide. Bulged portions formed on an outer surface of the ball guide are press-fit into the plunger-accommodating hole of the tensioner. | 10-23-2008 |
20080314002 | Medicine Dispensing/Packaging Apparatus - [PROBLEM] To provide a medicine dispensing/packaging apparatus capable of smoothly dispensing and packaging tablets for each package despite the fact that it is simple in structure and low in cost. | 12-25-2008 |
20080318718 | DOWNWARD ANGLE SETTABLE HYDRAULIC TENSIONER - In a hydraulic chain tensioner having a housing, a hollow plunger slidable in a plunger-accommodating hole in the housing, and a hollow sleeve extending into the plunger from a bottom of the plunger-accommodating hole, and a check valve mounted at the opposite end of the sleeve, a passage is provided on the outer surface of the sleeve to accelerate the balance of pressure between a first high pressure chamber between the check valve and the protruding end of the plunger and a second high pressure chamber between the inner end of the plunger and the bottom of the plunger-accommodating hole. In an alternative embodiment, balance is accelerated by communication between the second high pressure chamber and an oil reservoir inside the sleeve on the upstream side of the check valve. | 12-25-2008 |
20090143177 | TIMING CHAIN DRIVE UNIT - In an engine timing chain drive, a pivoted chain guide is provided on the tension side of the chain, and a synchronizing sprocket is incorporated into the chain guide and driven by the chain. The synchronizing sprocket rotates a cam which effects reciprocating movement of the guide to compensate for cyclic variations in tension resulting from operation of intake and exhaust valves. | 06-04-2009 |
20100059141 | MEDICINE DISPENSING/PACKAGING APPARATUS - A powder medicine dispensing/packaging apparatus includes: a divisional container | 03-11-2010 |
20100287270 | CONTROL PROXY APPARATUS AND CONTROL PROXY METHOD - A control proxy apparatus includes: a management-apparatus-information storage unit that stores identification information for uniquely identifying a management apparatus that manages various apparatuses and a communication format of the management apparatus; an apparatus-information storage unit that stores apparatus information for executing various types of control, in association with each control target apparatus; an authenticating unit that determines, when receiving a control request from the management apparatus, whether authentication information in the control request is stored in the management-apparatus-information storage unit; an apparatus-information acquiring unit that acquires, when the authenticating unit determines that the authentication information is stored in the management-apparatus-information storage unit, apparatus information corresponding to the control target apparatus, from the apparatus-information storage unit; and a control executing unit that converts control information in the control request based on the apparatus information acquired by the apparatus-information acquiring unit, and executes the converted control information on the control target apparatus. | 11-11-2010 |
