Title: Manufacture of copper-clad laminate containing inner layer circuit
Inventor: SASAKI MASAKI
IPC: H05K3/46
Filed: 1988-11-07
Abstract: PURPOSE:To prevent the outermost face of a copper foil from being rumpled and the copper foil from being cut, and to reduce its warp and change in size by a method wherein a coefficient of linear expansion of a specular sheet as a backing sheet to be used at a heating operation and a pressurization operation and a coefficient of linear expansion of the copper foil to be used are specified. CONSTITUTION:A coefficient of linear expansion in a range of 0.8 to 1.5 of a specular sheet against a coefficient of linear expansion at 1 of a copper foil to be used is selected and used as the specular sheet. When a ratio of the coefficient of linear expansion at 0.8 or lower of the specular sheet is used, a strain at a heating operation of the copper foil remains at a recessed part produced when a circuit is formed on an inside-layer circuit board and a rumple is caused in a resin flowing region of a prepreg during a heating operation and a pressurization operation because the coefficient of linear expansion of the copper foil is larger than that of the specular sheet. When a ratio of the coefficient of linear expansion at 1.5 or higher of the specular sheet is used, the copper sheet is pulled by the specular sheet in the resin flowing region of the prepreg during the heating operation and the pressurization operation because the coefficient of linear expansion of the copper foil is smaller than that of the specular sheet; the copper foil is easily cut by a generated tensile stress.

Title: Hot-water tank
Inventor: SAITO EIJI
IPC: E03D9/08
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To reduce heat radiation into outdoor air and improve power saving effect by a method wherein the exposed part of metallic components, such as a heater mounting plate and the like, is covered with a resin or the like having a small thermal conductivity. SOLUTION: A plate 5 made of a resin is superposed on the upper surface of a mounting plate 2a for a heater 2 to cover the upper surface of the mounting plate 2a with the resin plate 5, so as to constitute that the plate 2a will not be exposed. The resin plate 5 is fixed to a hot-water tank 1 together with the mounting plate 2a through mounting screws 3 in such a manner. Accordingly, the surface of the mounting plate 2a is covered by the resin plate 5 and, therefore, heat will not be released to the outside of the tank even when the heat of the hot-water tank 1 is transmitted to the mounting plate 2a, since the thermal conductivity of the resin plate 5 is small whereby the radiation of heat can be restrained nicely and the temperature retaining property of the hot-water tank 1 is improved, thereby permitting the reduction of the stand-by loss of the heater 2.

Title: Valve operating device of internal combustion engine
Inventor: YAMADA SHUNJI
IPC: F01L13/00
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To promote vaporization of fuel in cooling of engine by constituting a valve operating device in an internal combustion engine so that an intake valve may be opened in the compression or combustion stroke. SOLUTION: In cooling of an engine, intake and exhaust valves 1, 2 are made to perform the intake and exhaust actions as normal, and the intake valve 1 is slightly lifted by a very small cam lobe of a cam nose 11 in the expansion stroke in which cylinder pressure is high. High-temperature combustion gas is forcibly allowed to flow back, the temperature of the intake valve 1 is rapidly raised, fuel to be supplied from the fuel injection valve to an intake port 15 before the intake valve 1 is opened is heated by the contact of the intake valve 1 with a shade part 1a, and vaporization of fuel is promoted. Since the valve clearance is increased more than the cam lobe height of the cam nose 11 by thermal expansion of an engine head 16 after the engine is warmed up, the valve lift by the very small cam lobe is restrained, and forcible flowback of combustion gas is restrained.

Filed: 1988-11-07
Abstract: PURPOSE:To change the buoyancy applied to a control piece in a magnetic fluid and noiselessly drive a driven body interlocked with the control piece without using a motor by adjusting the magnetic field applied to the magnetic fluid. CONSTITUTION:When an electromagnet 6 is excited by a thyristor 7, the magnetic lines of force 10 generated by the electromagnet 6 are made denser toward the electromagnet 6 and coarser toward the upper section, and a magnetic field gradient is applied to a magnetic fluid 5. At this time, a plunger 2 is slowly lifted with no vibration due to the viscosity of the magnetic fluid. When the cage of an elevator reaches the position of the second floor (2F), the electromagnet 6 controls the cage so that its floor position is not moved via the signal from a cage position detecting device. At the time of descent, the excitation of the electromagnet 6 is weakened or cut off, then the plunger is smoothly lowered. Noiseless drive control can be performed, and a drive control device is made very simple in structure and small-sized.

Title: Optical disk stamper and manufacture of optical disk
Inventor: YAMAMOTO YUKITO
IPC: B29C45/37
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To eliminate a defective sector by deciding the height ratio of a groove part to a signal part within a specific range for a stamper used in the process of obtaining an optical disk substrate and thereby preventing a phenomenon such as pit deviation and double stamping. SOLUTION: The height ratio of the groove part to the signal part (prepit part) is set in the range from 1:0.8 to 1:1.3, for a stamper which is attached to a die for an injection molding machine and which is used in the process of obtaining an optical disk substrate through continuous injection molding. As a result, when the substrate separates from the stamper while contracting, the groove and its proximate prepit part separate simultaneously; therefore, the releasing state becomes uniform, eliminating pit deviation or double stamping. If the height of the prepit part exceeds 1.3 times that of the groove of the stamper, the releasing state lacks uniformity; conversely, if the height of the prepit part is made 0.8 times or less than that of the groove of the stamper, no sufficient signal characteristics can be obtained.
