Title: Manufacture of surface acoustic wave element
Inventor: MAKINO SHINGO
IPC: H03H3/08
Filed: 1984-10-11
Abstract: PURPOSE:To adjust the resonance frequency by etching a surface acoustic wave element not adjusted yet by means of an ion milling device using an element etching selectively a substrate member to adjust the effective film thickness of an electrode. CONSTITUTION:As the element etching selectively only the substrate member 1 such as a crystal substrate, oxygen is used and brought into the plasma state by the ion milling device and it is irradiated onto the surface acoustic element as an oxygen ion beam for etching; so-called the dry etching method. Since the oxygen ion beam gives less etching to an aluminum electrode 2 and considerably large etching to the substrate 1, the aluminum electrode 2 plays a role of a mask to the ion beam and then almost the substrate 1 only is etched.

Title: Siding material and composite siding material
Inventor: NAKAMURA TAMOTSU
IPC: E04F19/02
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To contrive to enhance thermal insulating properties or fire retardant properties and prevent the generation of warping or deformation by folding a backing member which is excellent in thermal insulating properties or dire retarding properties removably with a claw on the rear side. SOLUTION: Since a backing member 20 is mounted on the rear side, this sidling material claimed in this invention is excellent in the sense of heavy weight compared with a conventional siding material comprising an about 1mm thick synthetic resin board. Furthermore, since the backing material 20 is excellent in thermal insulating properties and fire retardant properties, it is possible to enhance the thermal insulating properties or the fire retardant properties of the siding material 2. Furthermore, the backing member 20 is removably mounted unlike a composite plastic-made siding material which has integrated the backing member 20, such as a thermal insulating material. Therefore, the siding material 2 and the backing member 20 are easily separated and recycolingly-dispososable by changes in the temperature of open air.  Thus construction makes it possible to provided an excellent heavy weight sense and moreover prevent the generation of warping or deformation even when the siding material 2 or the backing member 20 is repeated by expanded or contracted.

Title: Fuel injection valve
Inventor: YAMAMOTO YASUHIRO
IPC: F02M61/10
Filed: 1992-08-11
Abstract: PURPOSE:To reduce a speed of displacement so as to prevent secondary injection by communicating a damper chamber formed at the rear end of a needle with a pressure operating chamber via only a throttle passage formed between a recess and a projection when the needle is displaced in the direction where a fuel injection port is closed. CONSTITUTION:A recess 15 is formed at the rear end of a needle 4. A projection 16 is inserted into the recess 15 via the inner circumferential surface and a predetermined clearance 17 serving as a throttle passage so that a pressure operating chamber 18 is defined therebetween. A damper chamber 19, which is full of fuel, is formed at the rear end of the needle 4. At least when the needle 4 is displaced in the direction where a fuel injection port is opened, the damper chamber 19 is communicated with the pressure operating chamber 18 via only the throttle passage 17. Accordingly, as the needle 4 is displaced in the direction where the fuel injection port is closed, a pressure of fuel inside the damper chamber 19 is decreased, thus reducing a displacement speed of the needle 4. Consequently, the needle 4 is bounced, thereby preventing generation of secondary injection.
