Title: Piston in internal combustion engine
Inventor: USHIJIMA KENJI
IPC: F02F3/00
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of increase in frictional loss, and generation of noise when a piston sliding. SOLUTION: A single piston ring groove 5 for accommodating therein a piston ring is formed in a land part 4 which is connected with a skirt part 6 with a continuous curved surface so as to form a barrel shape, and minimum diameter clearances between the outer diameters of the land part 4 and the skirt part 6 and the inner diameter of a cylinder 7 are set to be less than 200 μm over the entire periphery of a piston while at least the land part 4 is made of a material having a small expansion coefficient. With this arrangement, the side surface of the piston may have sealability, and may be integrally incorporated with the piston ring. Thus, the frictional resistance can be decreased so as to reduce the weight of a crown part, thereby it is possible to minimize oscillation of the piston.

When the carriage 411 is moved, the light receiving section 132 is turned on at the point D2 and turned off at the point D3. The size of an original in X-direction can be detected from the pulse number of a X- direction driving motor during the movement of the carriage 411 between the points D2 and D3. Moreover, the size of the original in Y-direction can be detected from the pulse number of a carriage motor during the movement of the carriage 411 between the points D2 and D5. Therefore, the size of the original can be detected easily and highly accurately.

Title: Storage material for optical reading
Inventor: NOGAMI TAKASHI
IPC: B41M5/26
Filed: 1986-11-19
Abstract: PURPOSE:To obtain an optical memory having a sufficient performance, by using a specific organic compound as a storage material for optical reading. CONSTITUTION:A diazabicyclo [2,2,2] octane quaternary salt shown by a formula (I) or (II) can be easily synthesized by the reaction of a diazabicyclo [2,2,2] octane with an alkyl halide under the conditions for producing a conventional quaternary ammonium salt and has good thermal stability and ease of handling and can assure supply stability. In the uns-diazabicyclo [2,2,2] octane quaternary salt, phase transition occures at a specific temperature and the birefringence is eliminated due to the transition of crystalline state to amorphous state. Therefore, this compound is available as a material of a storage element converting thermal information to optical information of the presence of birefringence to store it.

Title: Device for confirming reception of camera
Inventor: IGAWA KAZUO
IPC: G03B17/18
Filed: 1984-12-28
Abstract: PURPOSE:To easily confirm the signal reception of a camera even from a far place or even if the circumference of the camera is bright, by providing a circuit for receiving signal and control circuit which causes an electronic flash device to emit lights in response to the signal reception of the circuit. CONSTITUTION:The main capacitor of an electronic flash circuit III is previously charged through a switch 2' after a switch 2 is closed and, when a signal transmitted from a remote place is received by means of a remote control receiving circuit I, a switch 3 is closed. When discriminating that the luminance of an object is low, a camera controlling circuit II gives a trigger signal to the circuit III and causes a flash lamp to emit light by means of the electric charge accumulated in the main capacitor, and thus, flash photographing is performed. When it is discriminated that the object is high in luminance, the light emission is performed after a shutter is closed. Therefore, the reception is confirmed by means of the light emission even when the transmitter is far and the circumference is bright and no special device is required. Accordingly, the necessity of enlarging the size of a camera is eliminated and cost increase of the camera can be avoided.

Title: Erroneous operation preventive circuit for speed meter
Inventor: ITO TADAO
IPC: G01P1/07
Filed: 1994-11-10
Abstract: PURPOSE: To prevent generation of error in a speed meter caused by chattering by disabling a period counter so long as the number of input pulses thereto is lower than a predetermined number. CONSTITUTION: Upon turning SW1 in a key switch 8 ON, a power reset circuit 2B is operated such that power is not supplied during a start lag time TR but a voltage VC is to the power reset circuit 2B upon elapse of the lag time TR. Consequently, a series of circuits from a pulse skip circuits 2C to a transmission circuit 2L are operated and then the pulse skip circuits 2C is reset by a control signal RST. When the SW2 is turned ON to operate an ignition circuit 6, several pulses are generated due to chattering and detected by the pulse skip circuits 2C which is thereby skipped. Since a period counter 2D does not count these pulses, error is prevented from being generated in a speed meter due to chattering.

Abstract: PURPOSE:To shorten running time in a base and to make it possible to manufacture a transistor simply at the good yield rate without deteriorating base resistance by providing a constitution wherein the potential in the conduction energy band of a second semiconductor material becomes higher than the conduction band of a third semiconductor material. CONSTITUTION:There is the discontinuance in a conduction band between the second semiconductor material and the third semiconductor material in a base layer (P<+> GaAs) 4a and a base layer (P<+> InGaAs) 4b. A staircase-shaped junction is provided so that the electron potential in the conduction band of the second semiconductor material is higher than that of the conduction band in the third semiconductor material. The fourth semiconductor material of a collector layer can be selectively etched with respect to the third semiconductor material.

The base layers 4a and 4b can be exposed by simple manufacturing steps, and the increase in external base resistance can be prevented. Thus, the heterojunction bipolar transistor characterized by high speed performance, easy manufacturing steps and high yield rate is obtained.
