Title: Plug socket with plug locking mechanism
Inventor: SHIBUYA NORIO
IPC: H01R13/639
Filed: 1993-11-25
Abstract: PURPOSE:To prevent the dropping out of a plug from a plug socket side by providing a plug locking mechanism formed of a projection part and a rotatably mounted spring member on the plug socket side. CONSTITUTION:A spring member 3 rotatably mounted by inserting both the end parts to the hole 4 of a projection part 5 is brought up above a plug socket 1, and a plug 6 is inserted to a power source feeding socket 1. After the insertion, the spring member 3 is rotated on the plug side with the hole 4 of the projection part 5 as the support point in the state where the plug socket 1 is in contact with the plug 6. A locking part 3a formed by curving in the center part of the spring member 3 is engaged with a plug rear end part 8 formed in the part connected to a cord 9 of the plug 6. When the plug socket 1 is electrically and mechanically connected to the plug 6, thus, the dropping out of the plug 6 from the plug socket 1 can be prevented by this engagement.

Title: Optical information recording medium and its manufacture
Inventor: SUGIYAMA TOSHINORI
IPC: G11B7/24047
Filed: 1986-12-12
Abstract: PURPOSE:To read a recording information with high SN ratio by regulating the projection speed of forming a base for the right angled or 45 deg. direction with the reference direction optionally set on a transparent base and composing the main refraction factor axis of the base with small dislocation. CONSTITUTION:At the time of the injection forming of a transparent base 2, a spiral signal pattern 1 is transferred on the recording film 3 thereof. The direction of a main refraction factor axis is set in the range of + or -3 deg. in the direction of Y-Y of the scanning direction which is the radial direction X-X of the base 2 and its right angled direction or of 45 deg.. An information reading is made possible at a high SN ratio by reducing the dislocation between the polarized plane of a recording and reproducing light and the main refraction factor axis. Owing to the injection speed of the base 2 being controlled later at the injection start time and completion time and earlier at the intermediate time the direction of the main refraction factor axis of the base can be aligned in a constant direction.

Title: Silicon substrate
Inventor: SUZUKI YOSHIAKI
IPC: H01L21/322
Filed: 1988-11-21
Abstract: PURPOSE:To improve the mechanical strength of a silicon substrate and prevent the electric characteristic and the yield of a semiconductor element from decreasing by making a surface containing specific concentration of oxygen. CONSTITUTION:Decrease of the mechanical strength of the surface of a silicon substrate for intrinsic gettering can be prevented by making said surface of the silicon substrate contain 1X10<18>atoms/cm<2> or higher concentration of oxygen. Therefore, a crystal defect such as dislocation hardly occurs even under the stress along the edge of the thin film pattern of a silicon oxide film, a silicon nitride film, etc., the mechanical substance of a semiconductor device, by installing the semiconductor device on the silicon substrate. Thereby the electric characteristic of a semiconductor element does not decrease and high-quality semiconductor devices can be obtained with high yield.

Abstract: PURPOSE:To provide a semiconductor integrated circuit capable of easily executing a test even in such a case that the number of the input pins of a chip is less than that of a macro-block to be tested. CONSTITUTION:The test signal synchronous to a clock signal CK is inputted to the input pin A of a macro-block 10 from an external connection pin 12.

This output is applied to the input pin B of the macro-block 10 through a multiplexer 11c. By this constitution, the period applying the tester signal after transition to the input pin A and the period applying the test signal before transition to the input pin B are formed.

Filed: 1987-11-25
Abstract: PURPOSE:To improve the rigidity of a magnetic bearing against the disturbance of a large amplitude at a low frequency and at the same time to improve the stability of a rotor against the natural vibration at a high frequency by setting a variable gain circuit between a position sensor and a PID control circuit. CONSTITUTION:An electromagnet 13 of a magnetic bearing is controlled by a PID control circuit 11 via an electromagnet power amplifier 12 based on the output signal of a position sensor 10 for a rotor. A variable gain circuit 14 is set between the sensor 10 and the circuit 11. This circuit 14 has a small output change to a small displacement change of the rotor and a large output change to a large displacement change of the rotor respectively. In other words, the rigidity of the magnetic bearing is improved against the disturbance of a large amplitude at a low frequency because the circuit 14 has a large output change with a large displacement of the rotor. While the stability of the rotor is improved against the natural vibration at a high frequency because the circuit 14 has a small output change with a small displacement of the rotor.
