Title: Switching system for circuit controller
Inventor: TANAKA AKIHIRO
IPC: H04L69/40
Filed: 1993-10-26
Abstract: PURPOSE:To ensure automatic recovery of data communication in a shorter time without causing an abnormal operation of an entire data communication system even when a procedure error occurs among data link layers due to the fault of a line switching circuit or an inter-equipment communication cable. CONSTITUTION:A procedure error occurs among data link layers while a line controller 10 operates as a working system device. Then the procedure error is detected by a circuit corresponding part 11 and reported to a CPU 40 via a microprocessor 13. Thus it is decided whether the corresponding circuit is kept in a communication mode or not. If so, it is decided whether a line controller 20 of a stand-by system is normal or not. If normal, it is decided whether the time elapsed from the precedent switching action is equal to a prescribed time or not. Thus the controller 10 is switched to the controller 20 only when the preceding elapsed time is equal to the prescribed time.

Abstract: PURPOSE: To improve the connecting strength of lead terminals by enhancing the fixing force of a land to the end of the terminal by solder, etc., in a semiconductor device in which the land of an integrated circuit board is fixed to the terminal by the solder, etc., and which is sealed by resin molding. CONSTITUTION: A lead terminal 23 has adjacent two leads (handgrips) 23b at the sites of the adjacent leads of the same potential, and a shared fixing piece 23a coupled to the ends. On the contrary, a wide land (b) wider than the combining allowance of the piece 23a is formed at the rear surface of the edge of a circuit board 10. Since the terminal 23 has the piece 23a having the width size of the sum or more of the widths of the leads 23b at the end, the fixing allowance becomes wider by soldering with the pieces 23a than the case of individually soldering the ends of the adjacent terminals, thereby enhancing the fixing strength. As a result, the connecting strength of the terminals is improved.

Abstract: PURPOSE:To determine life corresponding to a laser used precisely by giving a control section an alarm on the life of the laser when the supply voltage of an amplifier in an AOM driver is lowered to voltage lower than a controllable limit value by a predetermined voltage section. CONSTITUTION:When the driving time of a laser-beam generating section 1 is increased and an output P from laser power gradually lowers, modulation efficiency eta augments by the operation of a level control circuit in order to keep the output level Pd of laser beams on the surface D of a photosensitive body constant. That is, the supply voltage Vrf of an optical modulation element (AMO)2 and an amplifier (AMP)22 in a driver 21 also increases simultaneously, and the voltage Vrf is applied to one terminal for a comparator 26, and compared with voltage E1. The reference voltage (E1+E2) of a comparator 20 is set at a value equal to limit voltage Vrf' where modulation efficiency etacan be controlled, but the reference voltage E1 of the comparator 26 is set at a value lower than that by voltage E2. When the output P from laser power lowers and voltage Vrf reaches Vrf>E1, the comparator 26 transmits a laser-life signal through which the expiration of the life of a laser in a short time is messaged.

Abstract: PROBLEM TO BE SOLVED: To improve the corrosion resistance without damaging the characteristic of silver which is high in reflectance by employing an alloy reflecting layer which mainly consists of silver and contains gold as the reflecting layer of a back-surface reflecting mirror. SOLUTION: A back-surface reflecting mirror comprises a substrate 1 and a reflecting layer 2 formed on a back surface 11 of the substrate 1, the reflecting layer 2 is formed of an alloy reflecting layer mainly consisting of silver and containing gold.

On the contrary, when gold is contained in the reflecting layer 2 by over 30 wt.%, the reflectance is degraded, and no back-surface reflecting mirror of high reflectance can be obtained. Thus, it is preferable to regulate the content of gold in the alloy reflecting layer 2 is >=5 wt.% to <=30 wt.%. The film thickness of the alloy reflecting layer is preferably >=500 Åto <=3000 Å.
