Title: Method and device for transmission of data
Inventor: KOBAYASHI EIICHI
IPC: H04L7/00
Filed: 1984-08-27
Abstract: PURPOSE:To attain a data transmission system which secures a highly stable working with a simple circuit by converting an input code into a precoding code at the transmission side, delivering a synchronizing code at the reception side after detecting a specific pattern out of a received code and detecting the violation of the received code through a violation detecting circuit. CONSTITUTION:An input code (a) is expressed in a quadruple number (N=4) and therefore an operation is carried out by an adder circuit. Thus a precoded code (b) is obtained. A received code (g) is equal to the data signal underwent the polarity inversion control through a transmission part and transmitted via a transmission line. The code (g) is also supplied to a violation detecting circuit 25, and the violations are detected twice and continuously to a code that is intensionally operated at the transmission part. A single violation is detected in many cases to a code error due to noises, etc. When the violations are detected twice and continuously by a violation detecting circuit 26, the output of the circuit 25 is inhibited by a code error inhibiting circuit 27. In other cases, a code error signal (j) is delivered for a received signal.

Title: Manufacture of soft molding
Inventor: NAGATA MASATOSHI
IPC: B29C39/10
Filed: 1986-07-29
Abstract: PURPOSE:To prevent deformation of a skin body and to reduce the weight of a molding, by a method wherein the skin body having a hollow part is previously formed by using soft resin, and thereafter the hollow part is filled with a resin foaming material. CONSTITUTION:An outer surface is formed in a given molding shape, and a skin body 1 having a hollow part 10 is formed. A foaming resin material consisting of polyurethane resin is injected in a condition in that the skin body 1 is placed in a blow molding tool, and after the material is foamed and cured, a moulded prod is taken out. This method forms a resin foam 2 with which the skin body 1 is densely filled. Thus, since, during injection, strength of the skin body is high, even if foaming resin is foamed in the skin body, the skin body can be prevented from deformation.

Title: Formation of fine pattern
Inventor: NAGANO KAZUTOSHI
IPC: G03F1/76
Filed: 1985-08-13
Abstract: PURPOSE:To make almost no difference in size between the fine patterns formed in the first exposure and those formed in the second and subsequent exposures by a method wherein the exposing energy used in the second and subsequent exposures is made lower than the exposing energy of the first exposure using the photomask whereon a contrast emphasizing film is coated. CONSTITUTION:When a transmitted light is made incident on a CEL (contrast emphasizing film) 2, a bleaching action is generated corresponding to the intensity of the transmitted light, transmission factor becomes larger in a bleached region 6, the transmission factor becomes small in a non-bleached region 7 due to the feebleness of the transmitted light, and the contrast of the transmitted light of a photomask 1 is improved remarkably. At this point, when an exposure is performed continuously on a plurality of substrates or chips using the same exposing energy, the non-bleached region 67 of the CEL 2 is reduced in size every time an exposure is performed, and the effect of CEL goes out. In order to suppress the bleaching of the non-bleached region 7, the exposing energy used in the second and subsequent exposure is made lower than that used in the first exposure.

Title: Port controller for two-cycle engine
Inventor: YAMANAKA EIJI
IPC: F01L1/36
Filed: 1980-12-17
Abstract: PURPOSE: To modify the degree and timing of opening and closing of ports, by interlocking a port control member with a throttle valve and placing the control member between the outside of a cylinder liner and the inside of a cylinder block so that the control member can be displaced.  
     CONSTITUTION: An intermediate cylinder 9 is rotatably provided between the outside of a cylinder liner 2 and the inside of a cylinder block 1. The intermediate cylinder 9 is interlocked with the throttle valve 13 of a carburetor 12 through a lever 10 and a link mechanism 11. Since the open area of an intake port 3 and an exhaust port 4 is reduced in slow operation, the blowing of the mixture back to an intake pipe and the blowing of the mixture through to an exhaust pipe are prevented to reduce fuel consumption. Because the opening of the exhaust port 4 is delayed, output is heightened.

Abstract: PROBLEM TO BE SOLVED: To improve electric conductivity and oxidation resistance and to suppress the occurrence of migration by subjecting a silver coated copper powder composed of copper particles whose surfaces are coated with silver to heat treatment in a nonoxidizing atmosphere at specific temperature. SOLUTION: When small-diameter copper particles, whose surfaces are coated with metallic silver as a simple substance, are heat-treated in a nonoxidizing atmosphere, preferably in a weakly reducing atmosphere, at 150-600 deg.C, the metallic silver adhering to the surfaces is allowed to diffuse into the inner part of the copper particles. The resultant silver diffused copper powder has a composition consisting of 0.5-10 wt.% Ag and the balance Cu with inevitable impurities, and its particle size is desirably 0.1-10 μm. The particle shape of the silver diffused copper powder is a spherical shape with smooth surface, and an electrical conductive paste using the powder hardly causes migration although silver is contained in this powder.  Further, in order to obtain the silver coated copper powder to be heat treated, e.g. a process where silver ions are allowed to act on a copper powder in an aqueous solution of complex salt can be used.

Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To allow a solder bump connection to be correctly placed on a conductor and to have a proper standoff height for a device, by forming a conductor made of a material which cannot be soldered and providing a specially formed solderable region on the conductor. SOLUTION: A conductor 112 is printed on a substrate 10, and a pillar 114 is further formed on a surface 118 of the conductor 112 at a solder joint connection. As a stage for preparing for reflow, a solder bump 16 is aligned in position with an upper surface 114a of the pillar 114. The solder bump 16 is of a material which can reflow at a sufficiently low temperature, the conductor 112 is made of a material which cannot be soldered, and the pillar 114 is formed of a solderable material. As a result, the solder bump 16 forms a connection only on the pillar 114 after reflowing and is positioned. Further, a size and a shape of the pillar 114 defines a height, a shape and a distribution of a solder bump connection on the conductor 112 based on surface tension of molten solder alloy.
