Title: High resolution video signal compressing and transmitting device
Inventor: YAJIMA AKIHIKO
IPC: H04N19/00
Filed: 1991-06-03
Abstract: PURPOSE:To transmit a high fidelity image out of the standard of H.261 while keeping the compatibility of transmitting and encoding with the H.261. CONSTITUTION:An image having picture element four times as many as that specified by a CIF format is fetched from a signal source. This image is divided into the four pieces of 1st frame 101, 2nd frame 102, 3rd frame 103 and 4th frame 104, frame numbers are added and the divided pictures are transmitted and encoded based on the H.261 as the CIF format. The frame numbers are expressed by 4m+n ((m): four times frame numbers, 0<=m<=7, (n): position of CIF frame, 0<=n<=3 and therefore 0<=4m+n<=31) and the image encoding operation between frames is executed at the every four times frames. Thus, there is the effect of transmitting the high fidelity image while keeping the compatibility of transmitting and encoding with the H.261.

Title: Colored glass plate
Inventor: SUZUKI JUNICHI
IPC: C03C17/36
Filed: 1987-05-29
Abstract: PURPOSE:To obtain a colored glass plate exhibiting a gold color when viewed from a side and suitable for building, ornament, etc., by forming a multi-layer film having TiN layer and Ti layer and/or Cr layer as essential layers on a surface of a glass substrate. CONSTITUTION:The objective colored glass plate is produced by applying a multi-layer film composed essentially of a TiN layer and a Ti layer and/or Cr layer on a surface of a glass substrate e.g. by sputtering. When the colored glass plate is viewed from the side of the glass plate, it exhibits bright golden color which cannot be attained by the sole use of a TiN layer. Accordingly, the glass plate can be applied widely to building, shop decoration or ornamentation, etc., and, furthermore, it has sufficiently high durability when used in the above field.

Title: Display device
Inventor: OTSUKA YASUO
IPC: G02F1/13
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent temperature rise, to prevent dust and to make a device small in size and compact by putting the incident and emitting surface sides of a liquid crystal display element in hermetically sealed spaces and further connecting them to a wall surface cooling means being other part of the hermetically sealed space. SOLUTION: Since a display picture element area comes in contact with only the hermetically sealed spaces 2 and 3 surrounded by the liquid crystal display element 1, an incident side transparent member 4, an emitting side transparent member 5, a holding frame 6 and a panel plate 7, it does not touch the dust of outside air. A part of heat generated in the element 1 is conducted to the frame 6 and the plate 7 due to heat conduction and transferred to the outside of a liquid crystal display part 15. The rest of the heat is exchanged with gas inside the spaces 2 and 3 and transferred. Namely, a cooling fan 26 exchanges the heat inside the display part 15 consisting of the frame 6, the plate 7 and the members 4 and 5 so as to cool the display part 15.  Therefore, the prevention of dust is made compatible with heat radiation and further the entire device is miniaturized by miniaturizing the display part 15.

The region 14 forms a base in a parastic transistor. Gate electrodes 17 are formed on the region 12 through gate insulating films 16 extended up to the upper sections of the region 14 and the regions 15. A lower section in the region 14 is formed in the P<+> layer in high concentration in a double diffused type MOSFET having said constitution, thus preventing the breakdown of an FET generated by the operation of a parastic N-P-N transistor on the reverse recovery of a free wheel diode.

Filed: 1993-06-02
Abstract: PURPOSE:To reduce the noise and thinning of a background generated in binary images and to easily segment characters by binarizing multi value image data after executing a first derivative processing. CONSTITUTION:The image information of an X-ray film as converted to the multi value image data 10 (data representing the density values of 256 gradations for instance) by using an image scanner or the like similarly to a conventional case. Then, first derivative is applied on the multi value image data 10 and first derivative image data 50 are obtained.

Title: High electric power rf switch
Inventor: JOHANNESSEN PAUL R
IPC: H01H1/50
Filed: 1993-06-02
Abstract: PURPOSE: To open and close a switch in a short time and to permit quick switching without causing abrasion on the contact surface by pressure-contacting a flat link strip to an end after transversely inserting the link strip slightly isolated from a flat bus strip including a pair of input/output buses. CONSTITUTION: While a switch is operated to be closed, a pressure contacting block is separated so that a link can be inserted without causing any contact abrasion. Once the link is inserted into an upper gap G and lower gap G' of the pressure contacting block, a torque motor M is tuned on, and drive blocks #1 and #3 are driven together through a bevel gear line GT in a vertical direction (vertical arrow). As a result, the arm portions of U-shaped links #1 and #2 are pressure-contacted to a corresponding bus, and a pair of input/output buses #1 and #2 are electrically interconnected, respectively. When an appropriate pressure contacting force is obtained, the torque motor M is turned off to maintain pressure contacting so that the switch is kept closed.

Abstract: PURPOSE:To enable to increase the withstand voltage and prevent the generation of step cuts by a method wherein a composite film of a double layer film is used for a field insulation film, and a contact aperture is formed in a stepwise manner. CONSTITUTION:A vertical type N-P-N transistor is formed in a P type semiconductor substrate 1. Next, a thermal oxide Si oxide film 9 is formed as the first insulation film. Then, the first contact apertures 10-12 are provided in the film 9 by corresponding to an N<+> type emitter region 6, a P type base region 7, and an N<+> type collector region 8. An Si oxide film 13 produced by a CVD method is formed as the second insulation film. A phosphorus glass film 4 can be also formed on the film 13. Including the apertures 10-12, the second apertures 20- 22 wider than these apertures are formed in the films 13 and 14. Electrode patterns 15-17 are formed so as to cover the second contact parts. This construction enables to form a thick field oxide film without thickening the film 9, resulting in the prevention of the decrease in withstand voltage. Besides, the apertures become stepwise-formed, and accordingly the wiring step cut can be prevented.

Abstract: PURPOSE:To increase injection pressure at pre-injection and improve ignitability, by pressurizing fuel to be supplied to a pre-injection fuel chamber by means of a plunger having a small diameter pressure applying surface to carry out the pre-injection. CONSTITUTION:Fuel pressure is applied to a pressure receiving surface 38 of a plunger 31 to lift the plunger 31 and pressurize fuel in a pre-injection pump chamber 49. The pressure to the chamber is inverse to a ratio of an area of a large diameter pressure receiving surface 38 to that of a small diameter pressure applying surface 50, and the pressure in the pump chamber 49 becomes greater than that in a main fuel chamber 32. When the fuel in the pump chamber 49 is pressurized, the pressure is transmitted to a pre-injection fuel chamber 42, and a passage 44 is closed by a check valve 45, thereby feeding the fuel in the pre-injection fuel chamber 42 through a supply passage 43 to a pressure chamber 27. A needle 26 is lifted against a nozzle spring 30 to open an injection hole 28. As a result, the fuel in the pressure chamber 27 is injected from the injection hole 28.
