Title: Manufacture of semiconductor device
Inventor: SAKAI TATSURO
IPC: H01L21/302
Filed: 1985-12-04
Abstract: PURPOSE:To permit an overhanging structure of a semiconductor device to prevent the semiconductor device from becoming an improper external appearance such as stepwise disconnection of melted metal wirings or varying in characteristics by forming a nitride film by a vapor growth method in the semiconductor device, and etching it by a reactive ion etching. CONSTITUTION:A semiconductor device is formed in a 2-layer structures of lower layer oxide film 1 and an upper layer nitride film 2, and a holes 3 of an element region is formed. Thereafter, when a wet etching is executed to form emitter and contacting regions, the film 1 is remarkably etched due to different etching rate to form an overhanging structure 4. A nitride film 5 is deposited by a vapor-phase growing method to bury the holes 3. Thereafter, with the previously formed film 2 as a mask it is etched by active ion etching until a silicon surface 6 in the hole 3 is exposed. Thus, the film 5 remains at the overhanging portions 4 to eliminate the overhanging structure.

Title: Electronic still camera
Inventor: AIZAWA HIDEKUNI
IPC: G03B17/18
Filed: 1987-10-29
Abstract: PURPOSE:To make it possible for a user to perform a proper image pickup by displaying a value showing real shutter speed in image pickup. CONSTITUTION:The value showing the real shutter speed in the image pickup of an electronic still camera which uses a focal plane shutter 24 is displayed. Namely, the real shutter speed To(mm) in the image pickup in accordance with a stopped value A set by a diaphragm value setting dial 5 and the shutter speed set by a shutter speed setting dial 6 is displayed on a finder 3 or a liquid crystal display device 4. Since the real shutter speed in the image pickup is displayed, the user can perform the image pickup not by the set shutter speed but by using the real shutter speed in the image pickup.

Title: Optical information reader
Inventor: SUGIURA SATOSHI
IPC: G11B7/095
Filed: 1987-10-29
Abstract: PURPOSE:To adjust the relative position of a beam spot to a recording track or the inclination of the optical axis of a light beam to a recording surface by detecting the amplitude of a frequency component based upon the vibration of a beam spot and the phase to a reference signal. CONSTITUTION:The device is equipped with an optical pickup 3, a tilt motor 13, a tracking error signal generating circuit 17, an oscillator 18, an adder 19, a phase comparator 22, an amplitude detector 23 and a control signal generating circuit 24. If the optical axis of the light beam for information detection slants to the recording surface of the disk 2, the actual beam spot deviates from the center of the recording track although a tracking error becomes zero. In this state, the beam spot is vibrated to obtain an output signal of waveform from a band-pass filter BPF 21 to know the tilting direction of the optical axis from the phase relation of the output signal to a driving signal from the oscillator 18 and the tilting quantity of the optical axis from the amplitude. Consequently, the position of the beam spot or the tilt of the optical axis is adjusted.

Title: Visual field converter for endoscope
Inventor: TOJO YOSHIKAZU
IPC: A61B1/00
Filed: 1985-12-05
Abstract: PURPOSE:To convert exactly and smoothly the visual field of an endoscope by forming a driving member for turning a visual field converting member by a shape memory material and changing the form by heating to turn the visual field converting member. CONSTITUTION:Since a wire 11 is not heated because no current flows into the wire 11 under the state that a switch of a current supply part 14 is opened, the wire 11 is kept at short state (length l'), a mirror 8 is made approximately parallel with the optical axis of an objective lens 6 as shown by a broken line and the forward field can be observed through a direct observation window 18. When the switch 17 is closed, current is supplied to the wire 11, the wire 11 is heated by Joule heat generated from itself and turned to long state (length l). When the wire 11 is extended, a lever 9 and the mirror 8 are turned around a shaft 7 in the clockwise direction and the reflecting surface of the mirror 8 is inclined by 45 deg. e.g. from the optical axis of an objective lens 6. Consequently, a light beam passed through a side observing window 19 is reflected by the mirror 8 and made incident upon the objective lens 6, so that the side can be observe.

Title: Exciting circuit of electromagnetic flow meter
Inventor: TOMITA TOYOFUMI
IPC: G01F1/60
Filed: 1984-12-28
Abstract: PURPOSE:To output an accurate flow rate signal by varying the reference voltage of a constant current circuit according to the voltage variation of a circuit power source and varying an exciting current. CONSTITUTION:An on-off signal is outputted from a timing control circuit 6 at a specific period to turn on and off switches 61-63, and 64 and 65 alternately. For example, when the switches are set in an operation state shown in a figure, the voltage VN of a voltage variation compensating power source is superposed upon a reference source voltage VR and the resulting voltage is supplied as a reference voltage to an operational amplifier 43 while charging a charging capacitor 66; and charges of the capacitor 66 are applied to the amplifier 43 through the switch 64 in response to a next timing signal while having the opposite polarity. Consequently, the rectangular-wave reference voltage is applied to the amplifier 43 to turn on switching elements 67 and 68 alternately and constant currents are supplied to excitation coils 4 and 4'. Consequently, the constant currents are varied corresponding to variation in circuit source voltage to correct magnetic flux, thereby sampling an accurate flow rate signal having no error.

Title: Spring steel having superior settling fatigue resistance
Inventor: OKI YASUHIRO
IPC: C22C38/24
Filed: 1986-11-18
Abstract: PURPOSE:To improve the setting and fatigue resistances of a steel having a specified compsn. by adding specified amts. of W and Mo and/or V. CONSTITUTION:This spring steel consists of, by weight, 0.30-0.80% C, 0.50-2.00% Si, 0.40-1.50% Mn, 0.20-1.00% Cr, 0.04-0.10% Al, 0.03-1.00% W, 0.002-0.015% N, 0.05-2.00% Mo and/or 0.05-0.5% V and the balance Fe. In the steel, W forms forms carbide and precipitates during tempering to produced a fine precipitation strengthening effect. In case of <0.03% W, the amt. of the precipitate is insufficient. In case of >1.00% W, the effect is not further enhanced. When the amt. of Mo is <0.05%, Mo does not produce a satisfactory effect on setting and fatigue and >2.00% Mo is not effective in further improving the setting resistance. Though V makes the grains fine, increases the yield strength ratio and is effective in improving the setting resistance, <0.50% V does not produce the effect on setting and fatigue. In case of >0.5% V, insoluble alloy carbide remains as a mass and deteriorates the fatigue resistance.

Title: Gate control circuit
Inventor: WADA JUNICHI
IPC: H02M1/08
Filed: 1990-10-16
Abstract: PURPOSE:To protect an insulating gate bipolar transistor(IGBT) by lowering the gate voltage applied across the gate of the IGBT when the voltage across the collector and emitter of the IGBT is high while a prescribed control signal is supplied to the gate of the IGBT. CONSTITUTION:When a IGBT 3 is normally turned on, the gate voltage VGE of the IGBT shows a value close to a driving signal VS, because the voltage VCE across the collector and emitter of the IGBT 3 is low and a transistor 10 is turned off. When a load 2 is short-circuited, the voltage VCE becomes higher and, when the voltage VCE exceeds the voltage of a Zener diode 13, an electric current starts to flow to the base of the transistor 10 and the light receiving side 15 of a photocoupler provided to another related phase is operated. As a result, the collector current of another related IGBT of another phase is limited. Therefore, when either one of the IGBTs 3 makes protective operations against an overcurrent cause by an abnormal load, etc., the other IGBT can also make protective operations.
