Title: Pulse width modulator
Inventor: TOKUGE AKIO
IPC: H03K7/08
Filed: 1979-05-30
Abstract: PURPOSE:To achieve very simple constitution, by constituting nonstable multivibrator with gate IC and changing the oscillation period with the signal level through the application of audio signal to the input. CONSTITUTION:First, if an audio signal S2 is not fed to an input terminal 28, NAND circuits 21-23 as the gate IC repeat the inversion, at the time when the voltage Va at the contact (a) reaches the threshold voltage VTH of the NAND circuit 21 with charge and discharge of a capacitor 25 via a resistor 24. Thus, at the point (b), a rectangular wave having duty ratio 50% is obtained. When a signal S2 is fed to a terminal 28, depending that the terminal 28 is at positive or negative direction than the voltage VTH, the time when the voltage Va at the connection (a) reaches the voltage VTH is longer or shorter. Accordingly, the duty ratio of the output at the point (b) is changed with the level change of positive and negative direction of the signal S2 for pulse width modulation.

Title: Extruding method of spiral parts
Inventor: TSUKAMOTO EIHIKO
IPC: B21K1/30
Filed: 1983-04-14
Abstract: PURPOSE:To produce spiral parts having symmetrical tooth surfaces without requiring machining by pushing a blank material into a die which is inscribed with spiral grooves on the inside circumferential surface and extruding the same from one end side of the die then extruding again the material from the other side end of the die. CONSTITUTION:When a blank material 3 is extruded from one direction of a die 4, an underfill by DELTAS is produced on the tooth surface X on the side opposite from the extruding direction of the formed part 2. When the part 2 is thereafter extruded in the opposite direction by directing forward the surface X, an underfill DELTASY is produced on the tooth surface Y by the similar reason. The underfill DELTASY is smaller in value than the underfill DELTAS. The surface X having the initially produced underfill DELTAS receives the higher face pressure during extrusion from the opposite direction and therefore the underfill DELTAS is filled to the smaller underfill DELTASX which is approximately equal to DELTASY. The spiral part having the symmetrical tooth surfaces is thus obtd.

Title: Automatic pump
Inventor: NISHIMURA SHIYUNICHI
IPC: F04D13/16
Filed: 1979-05-30
Abstract: PURPOSE: To simplify the assembly work and reduce the escape of air from a pressure tank in an automatic pump by providing a branch water-passage in the upper- stream side of a delivery port and using a flexible pipe for the branch water-passage connected to the pressure tank to remove the weighting of the pressure tank to a pump part.  
     CONSTITUTION: Pumped-up water is risen from a pump 4 into a pressure chamber 6, and dropped through a water passage 14 to be delivered from a delivery port 8. In this construction, since the water to be delivered is not conducted through a pressure chamber 10 connected to the delivery 8 via a branch water-passage 12 separately above an electric motor 2, the air inside the pressure tank 10 is prevented from being involved in the delivery water. Besides, as a flexible pipe is used for the branch water-passage 12, the pump part 4 is free from the weight of the pressure tank 10, and the assembly work for a unit can be simplified. Furthermore, since the branch water-passage 12 is U-shaped and equipped under the bottom of the pressure tank 10, its whole capacity can be used for an effective capacity, and the whole unit can be small-sized.

Title: Liquid crystal display device and its manufacture
Inventor: MIYANO KAZUNORI
IPC: H05K3/32
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To avoid all position shifts between lead terminals of a flexible substrate and electrode terminals of a liquid crystal panel at the time of connection by predicting the rate of the sectorial expansion of the tip parts of the lead terminal part to the right and left due to pressure application and heating and arraying the electrode terminals in a sectorial shape. SOLUTION: The electrode terminals 3A on the glass substrate 2 of the liquid crystal panel are formed in the sectorial shape to the right and left around the center part of the electrode terminal group from the outside to the inside of the glass substrate 2 (a). This shape is determined by finding the rate of sectorial expansion of the tip parts of the lead terminals 6 of the flexible substrate 10 to the right and left by thermocompression bonding in advance. The lead terminals 6 of the flexible substrate 10 are positioned on the electrode terminals 3A of the glass substrate 2 across an anisotropic conductive film and bonded by thermcompression to expand the lead terminals 6 in the sectional shape, so that they are connected to the electrode terminals 3A with good position precision (b). Consequently, almost all horizontal and oblique shifts can be eliminated.

Abstract: PURPOSE:To form wiring patterns at a high accuracy by making almost uniform the etching speed in case of forming metallic wiring films of Al, etc. by performing selective etching by a method wherein a metallic film is formed on the surface of a substrate, then selective etching is performed, and simultaneously a light is irradiated onto the surface. CONSTITUTION:The metallic film 17 of Al, etc. is formed over the entire surface on the surface of the substrate 11. It is so formed that the metallic film 17, a P<+> layer 12, the substrate 11, an N<+> layer 14, and a P-well 13 obtain an ohmic contact via contact holes 16a-16d. Further, photo resists 18a-18d corresponded to desired patterns are formed on the surface of this metallic film 17 as masks. Then, selective etching is performed to the metallic film 17 on the surface of the substrate 11 by using etchant. Thereat, the light 21 is irradiated over the entire surface of the surface of the substrate 11 almost at the same time as the selective etching. This light 21 is a white light or a visible light ray of e.g. 1,500lux or more. Therefore, unnecessary metallic films on the surface of the substrate 11 are removed, and thus metallic wiring films 17a-17d, desired wiring patterns, can be formed uniformly.

Title: Warning device for low brightness of variable focus camera
Inventor: KODAIRA TAKAKI
IPC: G03B17/12
Filed: 1982-04-20
Abstract: PURPOSE:To give adequate warning of low brightness by providing a switch for changing threshold values of a comparator associatively with focal length switching in a low-brightness warning circuit. CONSTITUTION:When a main switch is turned on in low-brightness warning mode, a terminal 917b of the comparator 917 is held at a potential E1 determined by resistances 916 and 911. When the brightness of an object to be photographed is less than a specific value L1, the potential at a terminal 917a determined by a resistance 903 drops below the threshold value determined by the E1 to generate a signal 917c by the comparator 917, turning on an LED921. On the other hand, the switch 909 is closed for the 2nd focal length, so the terminal 917b is held at a potential E2 determined by the resitances 916, 910, and 911. When the brightness of the object to be photographed is less than a specific value L2, the LED921 is turned on as well as the 1st focal length. Thus, the adequate warning of low brightness corresponding to the focal length is generated.

Abstract: PURPOSE:To improve the accelerating and decelerating performance of a car by forbiding the internal capacity control of a variable displacement compressor except during the normal running of the car, and controlling the capacity of the compressor to the minimum during acceleration and to the maximum during deceleration, respectively. CONSTITUTION:When a car is in a normal running state, a variable displacement compressor 2 driven by an engine 12 for an air conditioning device is controlled in its internal capacity.
