IPC: F16K31/06
Filed: 1993-05-27
Abstract: PURPOSE:To obtain excellent liquid sealing ability and flow control performance by composing a directional control valve and a flow control valve using the above valve so that the land part of the outer periphery of a spool may come into contact with an annular seal to close a liquid path when the spool moves in a direction where passing each other between the land part of its outer periphery and the land part of the inner periphery of a cage body becomes maximum. CONSTITUTION:A directional control valve is composed so that a spool 4 may be about liquid-tightly and slidably inserted into a cage body 1 having an inlet port 2 and an outlet port 3, and the land part of the inner periphery of the cage body 1 and the land part of the outer periphery of the spool 4 may be passed each other for intermitting a liquid flow going from the inlet port 2 toward the outlet port 3 through an orifice 7. When an annular seal 11 made of an elastic material is liquid- tightly inserted into an annular groove provided on the inside of the cage body 1, and the spool 4 moves in a direction where passing each other between the land part of its outer periphery and the land part of the inner periphery of the cage body 1 becomes maximum, the edge of the land part of the outer periphery of the spool 4 comes into contact with the annular seal 11 to close a liquid path 8.

Abstract: PURPOSE:To make the device small-sized, light and low cost and to decrease the number of the parts by changing over simultaneously the linking condition from the motor of the transmitting side transporting driving system and the receiving side transporting driving system by the change-over driving source. CONSTITUTION:In the input output device used for the terminal equipment such as a facsimile, the paper advances to the left side after recording, and the paper is discharged by a discharging roller 5 after it is cut by the cutter composed of a fixed blade 11 and a rotating blade 12. At such a time, a recording part 10 is shifted to the left side for the half only of (a), or a feeding roller is shifted to the right side for the same quantity and the part is contacted to the feeding roller (platen roller), and thereby, the suitable recording can be executed. The residual paper after cutting is pulled back up to the initial position by a feeding roller 7 and a supplying roller 8. Thus, by shifting relatively in a fine quantity a head unit to form the reading part (closely tight sensor) and the recording part (thermal head) in a single body and one feeding roller 7 used for reading and writing, reading and recording can be respectively executed, the transporting path and the transporting driving system can be shared, the low price is widely improved and miniaturization can be easily executed.

Title: Optical recording medium
Inventor: TAKEUCHI TAKASHI
IPC: G11B7/24
Filed: 1981-08-17
Abstract: PURPOSE:To reproduce both information different from each other such as a picture  and sound simultaneously without scanning a recording medium, by forming respective  information recording layers on both faces of a substrate, which diffuses an incident  light, to read both information by the diffused light from a light source. CONSTITUTION:Photosensitive materials are used to form recording layers 2 and 3 on  both faces of a semitransparent and light diffusing substrate 1 (the diffused light is  intensified by mixing fluorescent matters to improve the SN ratio), and the sound signal and the picture signal are recorded on layers 2 and 3 respectively by irradiation of  the light. In this case, the light transmitted through photosensitive materials of one  layer is diffused uniformly by the substrate 1 and has no influence upon information  which is recorded on photosensitive materials of the other. As layers 2 and 3, films or  the like where respective information are recorded may be stuck instead of photosensitive materials. An optical recording medium 4 obtained in this manner is irradiated  with the light from a light source, and the reflected light from the layer 2 is focused  on an optical sensor 10 through a half mirror 6 and a lens 9 to reproduce sounds, and  pictures due to the diffused light to the layer 3 are projected onto a screen 8 through  a lens 7 to reproduce pictures.

Title: Electrostatically charging device for separation
Inventor: SENBA HISAAKI
IPC: G03G15/16
Filed: 1982-07-22
Abstract: PURPOSE:To separate a transferring material stably even when the peripheral speed of a photoreceptor varies by varying the amount of electrostatic charge for separation according to the peripheral speed of an image holder. CONSTITUTION:A gear 12 coaxial with the photoreceptor 1 rotates a saw-tooth disk 14 through a driving gear 13. A photodetector 15 engages the disk 14 to detect the rotation of the photoreceptor 1, and the detection result is monitored by a CPU 16. Therefore, when the peripheral speed of the photoreceptor is varied in life-size mode, that is detected by the CPU to output the voltage and current of an electrostatic charger 8 for separation to an output transformer HVT 17. When the peripheral speed is reduced in reduction-size mode, this processing is performed and such destaticization that retransfer to the transferring material is caused and charges on the transferring material are neutralized sufficiently is performed to separate the transferring material. When the peripheral speed is reduced for compensating deficiency in exposure in enlarged-size mode, a signal for lowering the voltage is sent similarly from the CPU to the charger 8.

IPC: H01L23/48
Filed: 1994-05-02
Abstract: PURPOSE:To provide a foil frame diode which decreases inductance loss by connecting a foil frame directly to a wafer, and also, forming the foil frame widely thereby increasing the area of the foil frame sharply. CONSTITUTION:A wafer 3 is provided at roughly center of the topside of a flat base 2 made of copper, and an anode electrode below a wafer 3 and a base 2 are connected with each other. Moreover, the tip of a foil frame 4 consisting of a copper foil is bent into a generally L shape, and the connection piece is connected directly to the cathode electrode on topside of a wafer 3. And, the connection is covered with silicon 7, and further then it is molded in the specified shape with epoxy resin 8. Moreover, the width of the frame 4 is put in roughly the same dimension as the width of the base 2, whereby the area of a conductor is increased sharply, and the current density is lowered, thus a foil frame diode where the inductance loss is decreased is obtained. Hereby, thanks to the foil frame, flexible mounting can be made.
