Title: Rotary compressor
Inventor: HIRANO KOJI
IPC: F04C18/356
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To reduce the leakage quantity of operating gas caused by the size of a spring hole inner side part biting into a blade groove between the side faces of a blade and the blade groove. SOLUTION: A coil spring 5 for energizing a blade 4 onto the roller side is provided on the base end part 42 side of the blade 4. A cylinder 1 has a blade groove 6 for guiding the blade 4 slidably, and a spring hole 8A for receiving the coil spring 5. The diameter of an outer side part 82 of the spring hole 8A almost corresponds to the diameter of a fixed part 52 larger than the diameter of a body 50 in the coil spring 5. The diameter of an inner side part 84 of the spring hole 8 is smaller than the diameter of the outer side part 82. The diameter of the inner side part 84 can therefore be made relatively smaller than the conventional one.

Title: Squid element having resistance layer
Inventor: YOKOZAWA KOICHI
IPC: G01R33/035
Filed: 1990-09-28
Abstract: PURPOSE:To prevent the destruction of an input coil due to an excessive current by arranging a resistor in parallel to the input coil of an SQUID. CONSTITUTION:An insulating layer 6 is laminated to an SQUID ring 4 and a membrane resistance layer 10 is further laminated thereto. When the superconductivity of an input coil is broken at any position by an excessive current to become normally conductive, the greater part of the excessive current is distributed not only to the part made normally conductive of the input coil 3 but also to the resistance layer 10 by the difference in resistivity to flow to both of them and absorbed in an earth point through an electrode 20. By this method, the excessive current continuously flows through the input coil 3 and the part made normally conductive is melted by the generation of heat to be prevented from cutting.

Title: Store signal control circuit for nonvolatile ram
Inventor: TAKEYA HIDEKI
IPC: G06F12/16
Filed: 1988-10-14
Abstract: PURPOSE:To reduce the possibility that a STORE signal is outputted in error even in the case of a CPU runaway by generating a store signal according to the output of a signal selecting circuit which selects an address signal and a data signal of a microcomputer optionally in combination. CONSTITUTION:A STORE signal control circuit 8 for a nonvolatile RAM (NVRAM) is equipped with the signal selecting circuit 4 which selects an address signal and a data signal of the CPU optionally in combination and generates the STORE signal according to the output of this signal selecting circuit 4. The signal selecting circuit 4 selects the specific address signal and data signal of the CPU to generate the STORE signal when the CPU writes specific data in a specific address of the NVRAM. Consequently, the STORE signal is prevented from easily being generated in the case of a CPU runaway and the generation conditions of the STORE signal are easily changed.

Abstract: PURPOSE:To enable measurement of a misregistratiorn amount by an electrical method after finishing of a diffusion process by applying a specified voltage to a metal pad and by measuring a voltage-to-current characteristics between adjacent metallic wirings. CONSTITUTION:Contact holes 10, and 8a to 8g are provided to each of a polysilicon wiring 3 and N<+>-diffusion layer parts 6a to 6g, an aluminum pad 9 and aluminum wirings 7a to 7g are formed and voltage-to-current characteristic of an MOS transistor is measured. If a gate electrode entirely crosses an N<+>-diffusion layer, characteristic of an MOS transistor is shown that the gate voltage is equal to a voltage applied to the aluminum pad 9; if it does not cross, characteristic is shown, that has both characteristic of an MOS transistor and a resistance amount which does not depend on a voltage applied to the pad 9. Therefore, it is possible to check misregistration in lithography during a gate electrode formation process and impurity diffusion layer formation process by following such change of voltage-characteristic.
