IPC: G03C1/73
Filed: 1990-03-08
Abstract: PURPOSE:To obtain a sufficient color developing density by forming a leuco dye which allows oxidation color development of a xanthene compd. having a cyclic amino group in the second position. CONSTITUTION:The leuco dye which allows the oxidation color development is formed of the xanthene compd. having the cyclic amino group in the second position. This leuco is the reduction type of the dye having one or two pieces of hydrogen atoms and develops a color by the addition of an additional electron when there these hydrogen atoms are removed or when there are these atoms, thereby forming the dye. This oxidation is attained by allowing a photooxidizing agent to exist.

IPC: B23K9/00
Filed: 1980-05-02
Abstract: PURPOSE: To suppress the formation of undercuts and improve welding speed with a simple means by giving a large retreat angle to the final trailing electrode.  
     CONSTITUTION: In automatic arc welding using multiple electrodes of 2 or 3 or more electrodes, the final trailing electrode wire 2 is provided with a retreat angle of θ 2 =20W50° with respect to materials 4 to be welded. A leading electrode wire 1 makes molten metal and molten slag, and advances while blowing these backward by its arc force. The arc of the wire 2 acts so as to hold down the molten metal  blown from forward on accont of its strong angle of inclination of said wire 2, thereby forming smooth and stable beads at the head width sufficiently wider than the  gouging width by the wire 1. Thereby, the formation of undercuts is suppressed  and the limiting speed for formation of undercuts is considerably improved.

Title: Diode array device and manufacture thereof
IPC: H01L21/82
Filed: 1992-03-16
Abstract: PURPOSE:To make it possible to reduce as much as possible an area occupied by a selection circuit that is excessively specified when it is normally used, and to render a wiring connection easy and appropriate with respect to a diode array containing a circuit for selecting a diode cell and a method for manufacturing a connection circuit, in which one of diode cells is short-circuited by heat breakdown. CONSTITUTION:Two diodes containing a p-n junction are inversely connected to each other. A one-way selection circuit 7 performs a process of selecting an arrangement interconnection that causes breakdown by applying a reverse voltage to the p-n junction. A process for selecting an arrangement interconnection in another direction executes short-circuiting of the p-n junction by causing light from a laser beam light source 9 to sweep along a specific interconnection among interconnections 4-1, 4-2,... arranged in that direction so that the interconnection can be exposed to a laser beam. Here, the reverse voltage and the laser beam are set to a value at which they cannot independently cause the p-n junction to be short-circuited.

Title: Semiconductor laser driving circuit
Inventor: ISHIZUKA ATSUO
IPC: H04B10/524
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To enable high quality signal transmission by having a rising pattern jitter in zero bias modulation reduced. SOLUTION: The larger the consecutive number of '0' code before '1' code of input data becomes, the longer a light emission delay time of a semiconductor laser 1 becomes. Then, if a semiconductor laser driving pulse signal is made to rise earlier by the light emission delay time in accordance with the consecutive number of the '0' code and, at the same time, its width is widened, light emission delay is compensated irrespective of the consecutive number of the '0' code and a pattern jitter can be eliminated. Thus, a '0' code consecutive number monitor part 2 monitors the consecutive number of the '0' code in the input data (a modulation signal), a pulse width adjustment circuit 3 makes a rising time of the semiconductor laser driving pulse signal earlier on the basis of the consecutive number of the '0' code before the '1' code of the input data and widens the pulse width.
