Title: Heat radiative wiring board
Inventor: YOKOYAMA KIYOSHI
IPC: H05K1/03
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To alleviate produced stress and enhance durability and reliability by bonding on a metallized layer a metal plate of a specific substance which has a specific porosity and a specific gradient of porosity from the interior toward the surface or from one side to the other side. SOLUTION: A heat radiative wiring board is obtained by bonding an aluminum nitride board 2 directly to a radiator 1. A metal plate 4 which is composed of at least one element selected from among Ag, Cu, and Al, has a porosity of 1-30% and 1-20% gradient of porosity from its interior toward its surface or from one side to the other side is joined thereto with a metallized layer 3 in-between. Ni plating 5 is given thereto and a semiconductor chip 7 is bonded through solder 6. Thus the Young's modulus of the metal plate 4 is reduced to make the metal plate 4 easy to deform, and thereby stress due to difference in thermal expansion coefficient between metal and ceramics is reduced to ensure high reliability for heat radiative wiring boards.

Filed: 1980-07-15
Abstract: PURPOSE:To obtain a binary coded output which receives no effect of shading, etc., by using plural image pickup devices and using the output of image pickup device of one side as a binary-coded threshold signal. CONSTITUTION:A detection pattern 4 is projected to an image pickup devices 7 and 9 through a lens 5. In this case, the device 7 is in focus and the device 9 is out of focus, respectively.

Title: Semiconductor memory
Inventor: IGUCHI TAKASHI
IPC: H01L27/10
Filed: 1993-04-22
Abstract: PURPOSE:To reduce an area on the side of an address line by extending the address line onto a logic circuit which constitutes an address decoder. CONSTITUTION:Wiring switching sections 14-16 are formed at several places of each address line. In the wiring switching sections, a signal A which flows into a gate line 121A flows into an upper second metal layer 122B and a signal -A reverse to the signal A, which flows into the gate line, which flows into an upper second metal layer 122A, flows into a lower gate line 121A. The face that the signals which have been flowing in the upper and the lower layer (these signals are reverse to each other) change places with each other apparently has the same effect that the signal which has been flowing in the lower gate line gets reversed. Therefore, this device has the same configuration as an equivalent circuit of a conventional address decoder and there is no necessity to have a space for forming an NAND circuit on the side of an address line formed region.

Abstract: PURPOSE:To obtain a zinc electrode which has prominent precisions in weight and in thickness and can be easily handled by using a porous metal of three-dimensional irregular meshes with connected pores and by coating the whole surface of the porous metal with zinc. CONSTITUTION:A positive-electrode case 4 is filled with a positive layer 6 made of, for example, silver or mercury and so on, on which a layer 7 is placed; the layer 7 serves as a separator as well as an electrolyte-holding material. A negative-electrode case 3, with a negative layer 5 of zinc in it, is used to seal the battery, thus constituting a button-type battery. The base material for the negative zinc-layer 5 in such a battery is a porous body of three-dimensional irregular meshes that has a metal skeleton and connected pores. The whole surface of the porous body is coated with zinc and then rolled to be used for the layer 5; the coated body alone is also used for the layer 5. It is preferred that the former porous body is made of copper and that the zinc used for coating is amalgamated. The coating of the porous body with zinc is conducted either by electroplating or hot dip coating.

Title: Control circuit for room lamp
IPC: H01H9/54
Filed: 1992-03-24
Abstract: PURPOSE:To provide a room lamp control circuit which dissolves the poor contact of a switch part and always keeps constant brightness by suppying base current through the first and the second resistance, shunting it in parallel to the second resistance to provide the first and the second transistor, and controlling a room lamp through the second transistor to select the second resistance. CONSTITUTION:When a door is closed, door switches 14, 15 are turned off, and a transistor TR1 is given base current through resistances R1, R2 and turned on, and a transistor TR2 therefore loses current to turn into an off-state, and a room lamp 11 is not lighted. When the door is opened, the door switch 14 or 15 is turned on, and the transistor TR1 is turned off, and the transistor TR2 is turned on through resistances R3, R4 to turn on a lamp 12. The ratio of the resistance R1 to that R2 is regulated to prevent the transistor TR1 from turning into an on-state even when contact resistances at the door switches 14, 15 increase. Thus the transistor TR2 controlled in the above way always gives the same current to the lamp 12.
