Title: Semiconductor device and production of the same
Inventor: NEGORO TATSUO
IPC: H01L21/764
Filed: 1977-09-27
Abstract: PURPOSE:To produce the device equivalent to SOS structure by laminating poly- Si on the insulaion film on monocrystlline Si, depositing a B2O3 film, etc. thereon and thermocompression bonding the same to other substrate and providing circuit elements to the monocrystalline Si. CONSTITUTION:SiO2 2 poly-Si 3 are superposed on monocrystalline Si 1 and B2 O3 dissolved in alcohol is coated and dried 4. On the other hand, the similar B2 O3 coating layer 4' is made on the monocrystalline Si 1' as well. When the layers 4, 4' are contacted and are heated to 1250 deg.C, the same become BSG 41, and the substrate 1, 1' are firmly bonded, Next, the substrate 1 is polished and chemical-etched to a required thickness. According to this construction, the poly-Si can be thin and the distortion of the substrate may be solved. SiO2 can be Si3N4 and B2O3 can belead or phosphorus glass. According to this method, BSG readily melts on heat treatment and therefore the heat treatment at the bonding or circuit formation cause the same to diffuse into the poly-Si thus obviating the breakdown of the insulation film. The use of PSG for N type Si and BSG for p type Si is desirable.

Title: Ultrasonic diagnosis apparatus
Inventor: NAKAMURA KENICHI
IPC: A61B8/14
Filed: 1983-06-28
Abstract: PURPOSE:To facilitate a wide band driving in the case of non-resonance driving and a high frequency burst driving by opening and closing alternately between a power source and a cable and between two ends of a parallel circuit of a stray capacity of the cable and an oscillator. CONSTITUTION:When a square wave driving signal A is put out from a driving circuit 12, a source voltage V0 is applied between output terminals M, N of a transmission circuit. In other words, a transmission signal B has a voltage V0 in a section K1. In a section K2 in which the output of the driving circuit 12 has a high level voltage V2, charge stored in a capacitor 4 which is a stray capacity of a cable 2 and an oscillator 3 is discharged through a switching circuit in the ON stage so that the voltage level of the transmission signal B becomes zero in the sec- tion K2. In the setion K3, the level of the transmission signal B becomes the source voltage V0. With this constitution, in the case of non-resonance driving, a square wave transmission signal B can be put out. Therefore, an ultrasonic output is not reduced much even in the high frequency region and the apparatus can be applied to a wide frequency band and a high frequency burst driving can be performed.

Title: Constant-current driving apparatus
Inventor: IMADA SHOGO
IPC: H02P8/12
Filed: 1994-05-30
Abstract: PURPOSE:To prevent the excessively large of a load current by setting the load current at the specified maximum load current during the time, when the reading of the load current by a load-current reading means is not performed, by a duty-ratio determining means. CONSTITUTION:The load current flowing through a driving coil 12a of a stepping motor, which is controlled by switching elements 14a1-4, is detected as the voltage, which is generated across both ends of a shunt resistor 13a1. The voltage is inputted into a microcomputer 11. The inputted load current and a specified current-preset value are compared, and the duty ratio is determined. The determination sets the load current stored in the microcomputer 11 as the maximum load current. Thus, the phenomenon that the load current actually flowing through the driving coil 12a becomes excessively large, can be prevented.

Title: Spot seizing prevention device
Inventor: INAI ATSUMI
IPC: G09G1/00
Filed: 1995-05-16
Abstract: PURPOSE: To avoid spot seizing more effectively by maximizing the luminance to reduce the electric charge remaining in a picture tube as much as possible at the time of turning off the power source of the picture tube. CONSTITUTION: A microcomputer 111 instructs a luminance adjustment circuit 105 to maximize the luminance just before an instruction of power-off. By the rise of the luminance of the signal, the cathode voltage outputted from an RGB output circuit 109 is minimized; and as the result, the anode current is increased and a large current flows to a picture tube 112, and the large- capacity staying electric charge is reduced. Thereafter, the microcomputer 111 turns off the power sources of the picture tube 112 and a circuit group to discharge the electric charge remaining in the picture tube. The appearance of local remaining of the spot on the fluorescent face of the picture tube is suppressed in comparison with the case that a high voltage is discharged at a time at the time of power-off, and as the result, local degradation of the fluorescent face of the picture tube is prevented.

Title: Eyepiece lens system
Inventor: HANGAWA MASASHI
IPC: G02B13/18
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To provide a small eyepiece lens system having a low cost and a wide apparent viewing angle and capable of observing an excellent object image over a whole screen by providing a lens having a concave surface on the side of an objective lens system, a negative lens and a positive lens in order from the side of the objective lens system. SOLUTION: This eyepiece lens system is provided, in order from the side of an objective lens system, with a first lens having a concave surface on the side of the objective lens system, at least a negative lens and at least a positive lens.

Title: Torque detecting device for rotary shaft
Inventor: GOTO YOSHIYUKI
IPC: G01L3/10
Filed: 1988-05-13
Abstract: PURPOSE:To obtain the high-accuracy detecting device which has no temperature dependency by varying the inductance of a detection coil with a rotation angle difference corresponding to torque and detecting variation in the oscillation frequency of a detector accompanying the inductance variation. CONSTITUTION:When a driven shaft 2 is rotated by a driving shaft 1, an elastic body 10 twists to generate the rotation angle difference on a rotary shaft. This angle difference causes variation in the confrontation area between detectors 31 and 32 composed of cavity coils and the number of lines of mutually coupling magnetic force varies to causes the variation in inductance. Consequently, the resonance frequency of a resonance circuit K varies and the oscillation frequency of a detection part provided outside the shaft varies. Then the quantities of variation in inductance of the detectors 31 and 32 correspond to the quantity of the torque, so the applied torque is detected from the quantity of variation in frequency. Thus, the high-accuracy detecting device which has no temperature dependency is obtained.
