Title: Screw tester
Inventor: KINO SHIGEO
IPC: G01M13/00
Filed: 1984-12-04
Abstract: PURPOSE:To measure uneven torque accurately, by mounting a cantilever on a female thread combined with a male thread of a combination thread for precision thread to engage the tip thereof with a load cell. CONSTITUTION:A cantilever 7 is fastened to a female thread 6 of a combination thread and a load cell 9 is engaged with the tip thereof. A motor 3 is started to transmit the rotation thereof to a male thread 5 through a coupling 2, a bearing 4 and the like. According to the rotation of the male thread 5, the female thread 6 moves in the axial direction of the male thread 5 and the cantilever 7 tends to turn according to the torque generated between both the threads. The resulting force is measure with the load cell 9 to detect the uneven torque of the combination thread. The axial movement of a load cell 9 enables precise detection of uneven torque. Moreover, joint arrangement of laser length measuring apparatus 12-15, a collimator 16 and the like permits simultaneous measurement of pitch errors.

Title: Refrigerator
Inventor: IIDA KENICHI
IPC: F25D19/00
Filed: 1988-10-11
Abstract: PURPOSE:To eliminate a piping connected to a muffler, to sharply increase a containing space in a machine room, and to prevent the generation of abnormal noise due to collision of refrigerant pipings with each other by a method wherein a muffler having a throttle part is mounted in a proper position between a vaporizer and a compressor. CONSTITUTION:In a freezing cycle, a muffler 11 provided at a part with a throttle part 11a is disposed between a compressor 8 and a vaporizer 5 togetherwith an accumulator. Through running of the compressor 8 refrigerant gas is compressed and is condensed by a condenser 9 for gasification. The pressure of the refrigerant gas is reduced by a pressure reducing device 12, the refrigerant gas is vaporized by the vaporizer 5 to form the freezing cycle, and a remaining refrigerant is accumulated in an accumulator 6 due to a change in an open air temperature. Further, when the compressor 8 is stopped, by means of a pressure difference between high and low pressures, high pressure refrigerant gas and oil are formed to flow reversely from the compressor 8 and stayed in a muffler 11. The muffler 11 is divided into two sections, and by mutually damping the pressure pulsation wave of the resonance frequency component of a mating muffler by means of primary and secondary mufflers 11b and 11c, gas resonance noise is prevented from generation.

Title: Dustproof door device
Inventor: OKAMOTO AKIHIKO
IPC: G11B33/02
Filed: 1991-10-02
Abstract: PURPOSE:To reduce the size of the above device and to obtain a high dustproof effect with simple constitution requiring lower costs by rotatably providing a 2nd door member on a 1st door member. CONSTITUTION:The 1st, 2nd door members 10, 13 are pressed to the end of a cartridge 6 to open an insertion port 2 when the cartridge 6 is successively inserted into the insertion port 2. The cartridge 6 is then admitted into the device and is loaded downward. Since the door member 10 is pulled upward by a coil spring 12, the force turning in a clockwise direction is added to turn the insertion port 2 in a closing direction. On the other hand, the door member 13 turns together with the member 10 in a bent state and comes into contact with the front surface of the cartridge 6 to slide the front surface. The member 13 receives the spring of a torsion spring 17 and exists on one straight line with the member 10 when the member 10 attains a perpendicular state. The insertion port 12 is thereby closed. The cartridge 6 receives discharge force and pushes the rear side of the members 10, 13 at the time of ejection. The cartridge is thereby discharged to the outside.

Title: Semiconductor device
Inventor: FUJISHIMA KAZUYASU
IPC: H01L27/04
Filed: 1985-11-14
Abstract: PURPOSE:To employ a semiconductor device as a P-N junction process monitor element between a semiconductor substrate as semiconductor device itself and a grounding terminal while forming an effective leakage path between the semiconductor substrate and the grounding terminal on practical use after the packaging of the semiconductor device by opening one part of the leakage path containing a leakage circuit between the semiconductor substrate and the grounding terminal for the substrate and closing the opening section by wire bonding. CONSTITUTION:In a semiconductor device incorporating a substrate-potential generating circuit with a leakage circuit, an opened bonding pad 4 is fitted, and the grounding terminal side of the leakage circuit 3 is connected to the bonding pad 4. Since the ground terminal side of the leakage circuit 3 is opened as the bonding pad 4, there is no stationary leakage path between a P-type substrate and the grounding terminal, thus allowing the monitoring of a semiconductor manufacturing process by evaluating a P-N junction between the P-type substrate and the grounding terminal. The bonding pad 4 is wire-bonded with the grounding terminal on practical use after the packaging of the semiconductor device, thus acquiring the characteristics of the substrate-potential generating circuit with the leakage circuit.

Title: Contact lens having thickness difference and its manufacture
Inventor: NEADLE SUSAN
IPC: G02C13/00
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To reduce substantial deviation from target refraction power by using different refraction power correction elements for cylindrical shafts which are finely divided. SOLUTION: Multiple base curves, namely multiple refraction force correction elements are used for the respective areas of cylindrical shafts. That is, the span of the 180 degrees of a cylindrical shaft range is divided into six areas having the ranges of 30 degrees. Then, three refraction power correction elements A, B and C are used. Since only three areas are required, the refraction power correction element A is used in 0-30 degrees, the refraction power correction element B in 30-60 degrees and the refraction power correction element C in 60-90 degrees. Fine correction is realized in the respective areas by using multiple base curves. In other words, refraction power is corrected by adjusting the cylindrical radius and spherical radius.  The spherical radius is made gradually smaller from the area A toward the area C, and the cylindrical radius is gradually made larger from the area A toward the area C.
