Title: Magneto-optical recording medium
Inventor: TOBISAWA TAKESHI
IPC: G11B11/105
Filed: 1990-06-29
Abstract: PURPOSE:To improve corrosion resistance, recording sensitivity and C/N by forming a reflecting layer of alloy films consisting of Si and inert metals, such as Au, Pt, Pd, Ag, and Cu. CONSTITUTION:The reflecting layer 5 consists of the alloy essentially consisting of at least one kind selected from the inert metals and the Si. Namely, the reflecting layer 5 essentially consisting of the inert metals and the Si has a high reflectivity at the boundary face with and adjacent magneto-optical recording layer 4 and is usable as the reflecting layer 5. Since this alloy has a low thermal conductivity, the diffusion of heat hardly arises and the sensitivity of recording and erasing is higher than that of the other reflecting layer. Further, this reflecting layer 5 is formed by using the chemically inert metals, the layer does not corrode. This alloy does not allow the permeation of moisture, corrosive gas, etc., has a low electrical conductivity and hardly allows the flow of corrosive currents and, therefore, the anode and cathode reaction hardly progress and the magneto-optical recording layer does not corrode. The magneto-optical recording medium 1 has excellent recording and reproducing characteristics and corrosion resistance in this way.

Title: Contactless ignitior for internal-combustion engine
Inventor: KOIKE HIROSHI
IPC: F02P5/155
Filed: 1983-09-21
Abstract: PURPOSE:To distinctly know the operation of an over-revolution preventing circuit by applying positive feedback into an output voltage comparing circuit from the output of a revolution-number detecting circuit and allowing the operation revolution number of the over-revolution preventing circuit to be provided with hysteresis. CONSTITUTION:In the range between t0 and t2 where the engine speed is low, the time in said range is long, so the voltage VC at a point C reaches a standard voltage VG at the intermediate time t1, and the output VD of a comparator 28 is shortcircuited before a standard voltage VH is reached, and a power transistor is cut-off by the output supplied from an ignition position control circuit, and ignition is performed. When the engine speed exceeds a set value, the output VD of the comparator 28 does not lower to L and charged, and at the time when the output VD reaches the standard voltage VH, the output VJ of a comparator 33 becomes H, and spark F is suspended. At this time, VJ increases, and also VD increases through a condenser 32, and operation is stabilized because positive feedback is applied. As the number of revolution increases and reduces, an over-revolution preventing circuit 20 operates, and the stop and recovery of spark are repeated.

IPC: F04D19/04
Filed: 1991-07-15
Abstract: PURPOSE:To increase collection of an oil component in a gas discharged from a pump driving part without blowing a lubricating oil out of an oil mist filter. CONSTITUTION:An oil pump 27 is shorted to a suction port and a discharge port 14 by a bypass piping 32, and a drain in an oil mist filter 31 for collecting oil is connected to this bypass piping so that those with large pressure loss can be adopted for the oil mist filter 31.

Title: Positioning control system
Inventor: KAI TAKAHIRO
IPC: G05D3/12
Filed: 1985-08-09
Abstract: PURPOSE:To always accurately position a linearly moving body even in case of the step-out phenomenon of a pulse motor occurs by detecting the extent of movement of the linearly moving body, for example, an X-Y table by a sensor and feeding back this extent of movement to compensate positioning. CONSTITUTION:Assuming that a designated movement extent (x) includes a maximum of a distance NX0.5l, a CPU 8 outputs MXN-number of pulses to a pulse motor 6 through a motor controller 7 for the purpose of moving an X-Y table 1 for the distance NX0.5l. Then, the X-Y table 1 is advanced from the initial position, and optical fiber type photoelectric switches 3 and 4 generate pulses each time when light is projected and received from a reflecting face 2c by movement of the X-Y table 1, and a counter 5 counts these pulses. Thereafter, a counted value C of the counter 5 is fetched, and it is judged whether this value C is equal to N or not. If the value C is equal to N, this state indicates that the X-Y table 1 is not advanced for the designated distance (x), and therefore, the remainder distance is operated, and the number of pulses to be supplied to the pulse motor which corresponds to this operated distance is operated, and pulses are supplied to the pulse motor 6 through the controller 7.

Title: Manufacture of semiconductor device
Inventor: KIRIYAMA SHUJI
IPC: H01L21/304
Filed: 1986-07-22
Abstract: PURPOSE:To obtain the method for manufacturing a semiconductor device, in which impurities do not remain on the surface of a silicon substrate, by removing an oxide film, which is formed on the silicon substrate, by using fluoric acid based etching liquid, immersing the surface of the silicon substrate in hydrogen-peroxide water for a specified time, and thereafter washing and drying the substrate. CONSTITUTION:When an oxide film remains on the surface of silicon at a part to be oxidized before the formation of a specified oxide film on the surface of the silicon in a wafer, dispersion in thickness of the oxide film at the actual oxidation is induced. Therefore, the silicon is immersed in fluoric acid liquid, and the oxide film on the silicon is removed. After the oxide film is removed, immersion treatment in hydrogen peroxide water is performed at the time of washing with water. The natural oxide film on the silicon depends on the concentration of the hydrogen peroxide water and the time of the immersion. In comparison with the case when the immersion treatment in the hydrogen peroxide water is not performed, the thickness becomes thick by about 1-3 Angstrom . The surface of the silicon is made inactive, and impurities are hard to be attached.

Abstract: PURPOSE:To achieve desired open/close function by varying the open/close speed of logic valve in random pattern by means of an external electric signal. CONSTITUTION:A high speed solenoid exchange valve 12 to be functioned by an electric signal provided from a signal generator 11 with exchange frequency higher than 50/sec is arranged in a pilot oil path 9 for releasing pressurized oil from a pilot chamber 13 between a tank 14. Since a poppet 3 will lift as oil is discharged from the pilot chamber 13, the open area of logic valve 10 can be varied by varying the ratio of on-off time of said valve 12. Consequently, when varying the ratio between the sampling time ts and exciting time ton, random opening responce can be obtained.
