Title: Digital encoder
Inventor: YAMAUCHI ETSURO
IPC: H04N7/01
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To reduce the circuit scale of the entire device by conducting processing of 1st and 2nd color difference information by one system. SOLUTION: Input information from an input terminal 1 is fed to data latch circuits 2, 3 and luminance information (Y) and 1st and 2nd color difference information sets (Cb , Cr ) are separated. The separated color difference information sets are fed to an interpolation circuit 6, from which interpolated information is fed to a multiplexer circuit 8 via a low pass filter 7. Furthermore, sine and cosine waveform information sets from terminals 9, 10 are fed to a selector circuit 11, and the waveform information selected alternately is fed to a multiplier circuit 8 at a timing (unit delay time) when the 1st and 2nd color difference information sets are provided. The selected waveform information is multiplied with the 1st and 2nd color difference information sets to conduct orthogonal biaxial modulation.  Then the modulated color difference information sets are fed to an adder circuit 12, in which the information is added to information delayed by a unit delay time and the result is extracted at an output terminal 14.

Title: Semiconductor device for power
Inventor: MORITA KOJI
IPC: H01L21/56
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To prevent the leakage of melted molding resin from inside a cavity toward a terminal for external connection in molding by forming a closing face with which a mold is brought into pressure contact, in a synthetic resin- made block formed at the base of the terminal for external connection through which the terminal for external connection passes. SOLUTION: In a semiconductor device for power, closing faces with which an upper die is brought into pressure contact are formed in an insulating blocks 3 of a connector 3 for power and in an insulating block 4b of a connector 4 for signal and the surface of the resist serves as a bottom face of the die. Due to this structure, the insulating blocks 3b, 4b and the resist substantially serve as a sealing material and therefore melted sealing resin 5 can be prevented from leaking outside from in a cavity in molding. As a result, even if a hole for storing a terminal is made large in the upper die 21 to allow a hole making work to be done easily, there is no burrs appearing in the periphery of a terminal 3a and in a face of the upper die 21 which would be brought into pressure contact with the resist.

Abstract: PURPOSE: To manufacture high-grade steel with low S and O 2  contents by pouring molten steel into a tightly sealed ladle, heating it with an electrode in the presence of molten slag having a specified composition, charging lime, and blowing an inert gas to agitate the molten steel.  
     CONSTITUTION: Molten steel 3 is poured into ladle 2 sealed with ladle cover 2a and sealant 9, and synthetic slag contg. 46% CaO and 49% SiO 2  in 1W1.5 ratio of CaO to SiO 2  is prepared. Electrode 7 for heating is dipped in molten slag 4 and supplied with electric current to heat steel 3 by resistance heat and raise the temp. At this time, the refractories of ladle 2 are hardly damaged by melting since the ratio of CaO to SiO 2  of slag 4 is 1W1.5. Lime is then charged from hopper 6, and an inert gas such as Ar is blown through lance 8 to agitate steel 3. By further blowing an inert gas through gas feed pipe 5 to adjust the O 2  content of the internal atmosphere of ladle 2 to ≤1%, steel 3 is refined to high-grade clean steel with low S and O 2  contents.

Title: Electrostatic recorder using optical fiber tube
Inventor: RIYOUDORI HIROMI
IPC: G03G15/04
Filed: 1980-04-15
Abstract: PURPOSE:To effectively prevent a stain on the projection face of an optical fiber tube (OFT), by providing a conductor layer on the surface of a terminal projection face except the projection face of the optical fiber tube. CONSTITUTION:OFT2 is covered with conductor 10 excluding projection part 9, and this conductor 10 is grounded to serve as an exposure part. Since almost all the surface of OFT2 is covered with conductor 10 kept at zero potential by grounding, electrostatic attachment of powder to OFT2 is effectively preventable. Since conductor 10 is cut on both sides of projection part 9, the tails of toner blocks do not tend to grow to part 9, thus permitting projection hindrance not to occur, and an image to be prevented from being cut.

Title: Material for preventing the fusion by pressing on embossing
Inventor: ARAI MICHIYUKI
IPC: B29C59/02
Filed: 1978-04-24
Abstract: PURPOSE: When a number of piled forming base materials are embossed, PTFE sheets coated with a powder of hard particles on both top and back surfaces are placed between the forming base materials, thus preventing the slippage between the materials.  
     CONSTITUTION: Two sheets of forming base material 1 are plied so that the surfaces to be embossed are set face to face. After an embossing plate 8 is laid between them, another forming base material is filed up thereon so that the back surface of that to be embossed are set face to face. Then, the material for preventing the fusion by pressing A is laid between the back surfaces 2. The material for preventing the fusion by pressing is prepared by coating PTFE sheets with a powders of hard particles made of, e.g., metal powder of sand, so that these particles project from the surface. Thus, when pressed in press 7, they do not slip, thus effecting precise embossing.
