Title: Hermetic reciprocating compressor
Inventor: YAMAGUCHI KENTARO
IPC: F04B39/00
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To downsize a delivery muffler, reduce the number of part items and reduce costs by interposing an inner pipe for connecting resonance chambers to each other in a throttle chamber of the delivery muffler, in a device wherein a plurality of resonance chambers are mutually communicated with each other through the throttle chamber, and the delivery muffler is mounted on the resonance chamber of a final stage. SOLUTION: For example, three resonance chambers 51 and two throttle chambers 53 are disposed in a delivery muffler 45. Namely, a resonance chamber 51a having an opening 49 is formed an initial stage, and is communicated to respective resonance chambers 51b, 51c of next stages through each of throttle chambers 53a, 53b in order. In this case, an inner pipe 57 for connecting respective resonance chambers 51b, 51c with each other is interposed in a throttle chamber 53b of the delivery muffler 45. A part of gas which flows from the resonance chamber 51b into the throttle chamber 53b is passed through the inner pipe 57, and delivery pulsation is reduced. It is thus possible to reduce the delivery pulsation simply and in a compact size without enlarging a muffler and sharply increasing costs.

Title: Wide angle zoom lens of small size
Inventor: IKEMORI KEIJI
IPC: G02B15/177
Filed: 1982-04-13
Abstract: PURPOSE:To obtain a wide angle zoom lens of a small size having excellent optical performance, by satisfying the prescribed conditions, in a lens system consisting, successively from an object side, of the 1st divergent group, the 2nd convergent group, and the 3rd convergent group. CONSTITUTION:Zooming is accomplished by moving the 1st group and the 2nd group on the optical axis in the lens system consisting, successively from an object side, the 1st divergent group, the 2nd convergent group and the 3rd convergent group. The conditions ¦fI¦<=fT,¦fII¦>=fT are satisfied where the focal length of the 1st group is designated as fI, the focal length of the 3rd group as fIII, and the focal length of the entire lens system in the zoom position at the telephone end as fT. The aberration as a whole of the zoom lens is compensated satisfactorily by said conditions. Even if the power of the 1st group is the same as the power of the 1st group of a conventional 2-group system, the power of the 2nd group is stronger, therefore, the reduction in the overall length is advantageous. The wide angle zoom lens of a small size having excellent performance is thus obtained.

IPC: F02M61/18
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To provide the manufacturing method of a fuel injection valve, which has a large angle of fuel spray by a simple method and atomizes fuel spray. SOLUTION: A nozzle hole 34 which is passed through a flat plate part 100a at an inclination angle α to a virtual axial line 101 in parallel with a center shaft perpendicular to the flat plate part 100a, is formed by press working in the flat plate part 100a of the base material 100 of a nozzle hole plate 32. 102 represents the center axial line of the nozzle hole 34. The center part of the flat plate part 100a in which the nozzle hole 34 is formed is recessed on a fuel injection side by a triangular cross sectional punch so as to form two slant flat surfaces 32a, and the nozzle hole 34 is inclined by further increasing an angle β to the virtual axial line 101. 103 is a perpendicular to the slant flat surfaces 32a. Hereby, the injection hole plate 32 having the nozzle hole 34 inclined at the angles (α+β) to the virtual axial line 101 can be formed. The inclination angle of the nozzle hole 34 can be increased by a simple working method, and an angle of fuel spray can be increased.

IPC: B29C45/67
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To shorten a molding cycle time while preventing the reduction of an opening and closing stroke by the thickness of a mold. SOLUTION: A mold clamping main cylinder 3 has a structure movable to a key locking possible position by a tie bar nut 5 and an A-block 9 for a key lock acts in a mold clamping direction and a B-block 10 acts in a mold loosening direction and mold clamping and opening belongs to the role of an auxiliary cylinder 6 and, in this process, the key lock does not act and only a ram and a movable plate are stroked and a heavy mold clamping piston is only slightly moved at a time of mold loosening. By this constitution, the heavy mold clamping pistone is made as impossible as to move and power efficiency is enhanced to open and close a mold at a high speed.

Title: Opening and closing device for vacuum line
Inventor: ARAKAWA YOSHIKI
IPC: F16K31/122
Filed: 1989-03-13
Abstract: PURPOSE:To prevent a valve unit from being damaged in its closing action of a vacuum line by supplying a pressure of fluid to the valve unit and an actuator cylinder by a solenoid valve providing a normally-opened flow path, in the case of a vacuum line opening and closing device using a vacuum valve. CONSTITUTION:A vacuum valve 1 provides a bellows-type valve unit 1a and an actuator cylinder 1b telescopically moved for moving this valve unit 1a, serving as a principal part. The first solenoid valve 2 forms a normally-closed flow path and a normally-opened flow path. The second solenoid valve 4 forms a normally-opened flow path. Since the vacuum valve 1 performs closing action of a vacuum line, it can be closed even when the first and second solenoid valves 2 and 4 are not energized because of power interruption. Thus, the valve unit is prevented from its damage in its closing action of the vacuum line.

Filed: 1987-03-17
Abstract: PURPOSE:To attain low price and miniaturization of an optical head part by including a non-liner optical medium layer in a disk and focusing an optical beam to an information carrier surface by the self-converging effect of the incident beam to the disk. CONSTITUTION:When an optical beam 2 to pass through a protecting layer 11a is made incident on a non-linear medium layer 11b, for the refractive index distribution of the non-linear medium 11b, the center is high, the circumference is low and the optical beam 2 is converged onto an information carrier surface 11c. Here, the optical beam 2 modulated by the information carrier passes through a protecting layer 11b and is made incident on a photodetector 12. By dividing the photodetector 12 into two or four, the track dislocation detection by the push-pull method, time gap method, etc., can be executed. At such a time, since there is the possibility that the optical spot on the photodetector 12 is moved by the pursuit of the track, and the comparatively large and wide optical spot is photodetected on the photodetector 12, the influence is smaller.

Abstract: PURPOSE: To obtain a semiconductor device in which initial trimming of resistance is effected by depositing silicon oxide on silicon nitride while specifying the thickness thereof and then irradiating the silicon oxide with a laser beam. CONSTITUTION: At first, the thickness of silicon oxide 9 is selected between (2/3+2n)/4×λ/1.41 and (4/3+2n)/4×λ/1.41, where λ is the wavelength of irradiation laser beam 20 and (n) is an arbitrary integer larger than 0. When the laser 20 impinges on the silicon oxide 9 through the upper atmosphere, the laser beam 20 is reflected 21, 22, respectively, on the silicon oxide 9 and the interface between the silicon oxide 9 and a silicon nitride 8. But since the wavelength of the laser beam 20 and the thickness of silicon oxide 9 are selected, the sum of the intensity of the reflected lights 21, 22 becomes 0 because of the phase difference and the laser beam 20 is utilized entirely for trimming a thin film resistor 5. Consequently, deficiency of laser power can be prevented at the time of trimming.
