| 20090242668 | Fuel Injection Valve and Method for Forming Orifice Thereof - A fuel injection valve comprises a convex portion prominently formed on an outer end surface of a nozzle body, stepped recesses each of which has plural steps formed by press forming on the convex portion, and multi orifices as fuel nozzle holes formed by press forming so that an outlet of each of the orifices is located at a bottom face of each of the stepped recesses. Furthermore, the fuel injection valve has plural sets each of which comprises one of the stepped recesses and the relevant orifice, the orifices incline to each other, and a step on a downstream side in each of the stepped recesses has a larger diameter than a step on an upstream side thereof. | 10-01-2009 |
| 20100229385 | Method of Processing Orifice - Disclosed herein is a method for processing an orifice capable of processing recessed portions and orifices, each having a unique hole diameter different from each other, to high positioning accuracy and in a short time. | 09-16-2010 |
| 20110005077 | Method of Machining Orifice and Press-Working Method - It is an object of the present invention to enhance the orifice design freedom and easy machin ability in a fuel injection valve in which orifices are formed by press-working. | 01-13-2011 |
| 20110011954 | Fuel Injection Valve and Machining Method for Nozzle - A fuel injection valve with reduced adhesion of deposits to a fuel injecting portion and superior in durability is provided. Also provided is a method for machining multi-orifice type fuel injecting portions easily, less expensively, in good surface roughness, in high productivity, and with few variations in shape, accuracy and surface roughness, using inexpensive equipment. The surface roughness of fuel injecting portions comprising orifices and apertures is made Rz 2 μm or less. Apertures are formed by press working so as to each have a plastic-worked surface of Rz 0.2 μm or less in surface roughness and then orifices are formed in the bottoms of the apertures so as to have a plastic-worked surface of Rz 0.2 μm or less in surface roughness. Further, when abrasion resistance of the nozzle is required, the fuel injecting portions are finished to a surface roughness of Rz 2 μm by quenching. | 01-20-2011 |
| 20110042490 | Fuel Injection Valve and Method for Coupling Two Components Together - There is provided a coupling process whereby two components can be coupled together at high positional precision regardless of precision of a single component. A softer component | 02-24-2011 |

| 20080203302 | SAMPLE TRANSFER UNIT AND SAMPLE TRANSFERRING METHOD - There is provided a mini environment type transfer unit which can efficiently transfer a sample to a critical dimension scanning electron microscope (CD-SEM) even in the case of use of a SMIF pod which can store only one photomask. In addition to a load port, a stocker which can store a plurality of photomasks is provided in the mini environment type transfer unit. A mask storage slot in which a plurality of storage units are stacked is provided in the stocker, and one photomask is stored in each storage unit. A sensor is provided in each storage unit to determine whether or not the photomask is normally stored. Additionally, a sensor is provided in each storage unit to detect whether or not the photomask exists. | 08-28-2008 |
| 20100230592 | Sample Transfer Unit and Sample Transferring Method - There is provided a mini environment type transfer unit which can efficiently transfer a sample to a critical dimension scanning electron microscope (CD-SEM) even in the case of use of a SMIF pod which can store only one photomask. In addition to a load port, a stocker which can store a plurality of photomasks is provided in the mini environment type transfer unit. A mask storage slot in which a plurality of storage units are stacked is provided in the stocker, and one photomask is stored in each storage unit. A sensor is provided in each storage unit to determine whether or not the photomask is normally stored. Additionally, a sensor is provided in each storage unit to detect whether or not the photomask exists. | 09-16-2010 |
| 20110142578 | SAMPLE CONVEYING MECHANISM - A sample conveying mechanism minimizes a risk of damage to a sample typified particularly by a photomask, and the sample conveying mechanism provides the sample retention mechanism for holding the sample so as to be suspended and is configured such that a portion close to a pattern surface of the sample is separated from a projection section of a flange for suspending the sample, thereby inhibiting a contact between the pattern surface and members configuring the conveying mechanism. | 06-16-2011 |
