Title: Method for constituting optical disk device
Inventor: SAKUYAMA HIROYUKI
IPC: G11B7/135
Filed: 1993-07-23
Abstract: PURPOSE:To arbitrarily use plural kinds of optical disks in different recording density by equipping plural objective lenses which are different in specifications and selectively using an objective lens suitable for a loaded optical disk. CONSTITUTION:When a disk cartridge 1 is inserted into the device, the presence of a hole 1c is detected by a cartridge hole sensor 7. Then, in the case of standard specification cartridge without the hole 1c, a mirror driving device 6 is driven to form an optical path between a fixed optical system 2 and a polarization prism 35 by reflecting a laser beam with a mirror 5 by using an objective lens 32. On the other hand, when a nonstandard specification cartridge with the hole 1c is inserted, the mirror 5 is turned at 45 degrees and the laser beam is reflected with a mirror 4 by using an objective lens 31 to form an optical path between the optical system 2 and a polarization prism 34. Consequently, either of the standard and nonstandard disk cartridges can be used.

Title: Leak preventer of motor for refrigerant compressor
Inventor: TAKEO YUJI
IPC: H02H7/122
Filed: 1993-08-16
Abstract: PURPOSE:To prevent trouble caused by leakage of a motor compressor, i.e., a refrigerant compressor and a motor housed in one housing, using a small and inexpensive preventer. CONSTITUTION:A refrigerant compressor and a motor 3 are housed in a housing 4 being held while being insulated from a vehicle. The housing 4 is connected with the minus side of a power supply 15 through a leak detection resistor 21. Voltage of the leak detection resistor 21 is monitored by a leak detection circuit 20 which delivers a leak detection signal to a control section 17 for an inverter bridge 16 when the voltage of the resistor 21 reaches a predetermined level. Upon receiving the leak detection signal, the control section 17 interrupts the control of the inverter bridge 16 thus stopping the motor 3. Since the leak can be detected simply by monitoring the voltage of the leak detection resistor 21, a small and inexpensive leak preventer can be realized.

Title: Motor controller
Inventor: MIYAJI SHIGERU
IPC: H02P21/22
Filed: 1984-09-27
Abstract: PURPOSE:To reduce the cost by intermittently supplying power to a motor in response to the amplitude relation between the load current and the set value of a motor, thereby eliminating a torque sensor or a limit switch. CONSTITUTION:When a contact 3 is closed, a flip-flop 5 is set, and a flip-flop 6 is reset. Then, a switching element 7 is ON, a switching element 8 is OFF, a motor 9 is normally rotated to open a valve. When the valve arrives at the opening end position, the load torque of the motor 9 abrupting increases to rapidly increase the load current of the motor. A load current monitor 11 compares the load current with the set value, and when the load current increases larger than the set value, a timer circuit 15 operates. When the counting of the timer 15 is completed, if the load current is still larger than the set value, the output of an AND gate 16 becomes 'H', and the flip-flop 5 is reset by a signal from the gate 2, and the element 7 is turned OFF.

Filed: 1982-11-19
Abstract: PURPOSE:To prevent the damage of a thin insulating film due to charging in the manufacturing steps by connecting a metal film or an insulator film on a thin insulating film to a semiconductor substrate. CONSTITUTION:The surface of a P type Si substrate 1 is separated by a field oxidized film 2, an N type layer 5 and a P added polysilicon thin film electrode 4 is formed through a window 6 of a thin oxidized film 3, an insulating film 7 is superposed, and the later steps are executed thereon as required. According to this structure, even if the surface of the semiconductor device is electrostatically charged after the electrode 4 of the capacity unit is formed, the electrode 4 is coupled to the substrate 1 through a P-N junction formed at the substrate 1. Accordingly, voltage difference is not almost produced in the forward direction, and the voltage difference higher than the withstand strength of the P-N junction is not produced in reverse direction. When the reverse withstand strength of the P-N junction is selected to a value lower than the withstand strength of the film 3, the insulation of the film 3 between the electrode 4 and the substrate 1 does not break down. Accordingly, the film 3 of the capacity unit is reduced in thickness, thereby microminiaturizing the pattern, the decrease in the quality is prevented, and the yield can be improved.

Title: Hydraulic control device for antiskid device
Inventor: ARIKAWA TETSUO
IPC: B60T8/1766
Filed: 1985-09-13
Abstract: PURPOSE:To enable to take a measure to counter failure in operation, by a method wherein, when the one piping system fails in operation, a piston is moved in one-way by means of a differential pressure between two liquid pressure generating chambers to forcibly close a valve part, opening and closing a passage of the other normal piping system, to reduce the moving distance of a brake pedal. CONSTITUTION:When the one piping system 3 fails in operation, liquid pressures, exerted on both end surface of the one large part 41a of a piston 38, are 0, liquid pressures, exerted on both end surfaces of the other large part 41b, are about equal to each other, the piston 38 is not moved as it is left in a neutral position, and a valve ball 47b is separated from a valve seat 46b. This feeds pressure liquid to wheel cylinders 7b and 12a of a front wheel 6b and a rear wheel 11a, respectively, of the other normal piping system 16 to ensure a brake force. Immediately after the piston 38 is moved, or even if a movement distance is slight, the liquid pressure of a wheel cylinder 12a of rear wheels 11a is started to increase, and this reduces incurring of working liquid loss and decreases a moving distance of a brake pedal 2.

Title: Construction for strengthening carrier mobility in semiconductor on insulator
Inventor: MASSIMO VINCENZO FISCHETTI
IPC: H01L29/786
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To raise the mobility of holes and electrons, by causing a first region of a semiconductor layer to surround a second region nearly, making the first region larger than the initial volume of a substance, causing the second region to receive a compressive stress, taking the regeneration of a valence band off in consequence, and decreasing the band edge mass of a carrier such as a hole and so forth. SOLUTION: By oxidation of a peripheral region to be protected by a mask 116, a silicon dioxide surrounding silicon below the mask 116 expands. A layer 114 not being protected is perfectly oxidized and an oxide layer 118 is formed, and a silicon region 119 remains from the layer 114. The mask 116 remains on the silicon region 119. The expansion of volume of the silicon dioxide is slightly larger than the factor of 2, and the molecular weight of the silicon amounts to 12.056 cm<3> . By this expansion, a compressive stress is generated in the silicon region 119 between them. It is possible to form an element such as a p-channel field-effect transistor, etc., on the silicon region 119, following exfoliation of the mask 116. Hole mobility is improved by the compression stress.

Title: Surface treatment for metal
Inventor: MIYAUCHI EIZO
IPC: H05H13/04
Filed: 1990-07-31
Abstract: PURPOSE:To remove adsorbed contaminants from the surface in the synchrotron orbital radiant light irradiated region by irradiating a metal with synchrotron orbital radiant light in an atmosphere containing a gas liable to combine with carbon or in vacuum. CONSTITUTION:A metal is placed in an atmosphere containing a gas liable to combine with carbon, such as gases of oxygen, hydrogen, chlorine, etc., or in vacuum, and this metal is irradiated with synchrotron orbital radiant light. At this time, the above metal can be irradiated with the synchrotron orbital radiant light in the state reflected by a metallic film mirror. As a result, contaminants, such as carbon, adsorbed by the metallic surface in the part to which polishing cannot be applied are excited by the high energy radiant light, released from the surface, and removed. Further, if the temp. of the above metal is regulated to a temp. not lower than ordinary temp., e.g., about 200-300 deg.C, the energy of the contaminants is increased and the removal of the contaminant is facilitated, and moreover, if the metal is previously polished, the removal of the contaminants is facilitated to a greater extent because the amount of the contaminants on the surface is remarkably reduced.
