Title: Manufacture of printed wiring board
Inventor: YAGI TOSHIAKI
IPC: H05K3/26
Filed: 1991-08-29
Abstract: PURPOSE:To improve the solder-connection reliability of mounted components with a single-sided printed wiring board on which the components are mounted without deteriorating various characteristics, such as the electric characteristic, etc., by performing oxidizing or acid treatment on a punched circuit face with permanganate, concentrated sulfuric acid, etc., after polishing and cleaning the punched circuit surface. CONSTITUTION:Since land sections connected with lead wires of a components mounted on a single-sided printed wiring board are reduced in thickness by the thickness of a solder resist, projecting burrs or unhardened attachment can be removed with a brush. However, when an epoxy resin, etc., adheres to and cures on the land sections, they cannot be removed with the brush. Therefore, oxidizing or acid treatment is performed after bushing so as to completely remove the contamination on the lands. Permanganate, chromic acid, concentrated sulfuric acid, etc., can be used for the above-mentioned treatment, but the most preferable chemical is the salt of an oxidizing agent, such as permanganate, etc. In addition, it is also preferable to perform a surface cleaning, degreasing, water-washing, neutralizing processes before and after the oxidizing or acid treatment.

Title: Power supply system for traveling-wave tube
Inventor: KAWAHARA TAKESHI
IPC: H01J25/34
Filed: 1983-11-22
Abstract: PURPOSE:To devise protection of a traveling-wave tube by turning off a bias switch circuit of a delay circuit for supplying a voltage to the anode electrode when the helix current exceeds a specified value and interrupting the input power source when the on-off frequency reaches a predetermined value. CONSTITUTION:A primary power is supplied to an anode electrode voltage supply circuit 4 and a helix electrode voltage supply circuit 7 from a terminal 1. A bias voltage VB is applied to a delay circuit 2 through a switch circuit 3 from a terminal 5 and after several seconds the voltage is applied also to the circuit 4 and a voltage VA is applied to the anode electrode. When a helix current detecting circuit 9 detects a current exceeding a specified value the circuit 3 is turned off. At this time the output signals of detecting circuits 10, 11 operate a counter circuit 13 through a gate circuit 12 and when the counted value of the circuit 13 reaches a specified value a driving circuit 14 is operated to drive an external switch element connected to the circuit 14 and the input from the power supply is interrupted. In this manner, the failure of the traveling- wave tube due to the increase of the helix current can be prevented.

Abstract: PURPOSE:To increase the DC current gain of a hetero junction bipolar transistor by forming that a band gap transition region at the side of a collector layer drom the p-n junction position inverted in the conductive type toward the collector from a base, thereby shortening the switching time. CONSTITUTION:An n type GaAs collector layer 2 is formed on an n<+> type GaAs substrate 1 of high impurity density while adding Si by using a molecular beam epitaxie unit. The composition is gradually varied by controlling aluminum flow rate in a band gap transition region 3. The growth of the n type GaAs is continued, the impurity is switched from Si to Be, thereby forming a p type GaAs base layer 4. The n type emitter layer 5 of Ga1-xAlxAs is grown, and emitter, base and collector electrodes 6, 7, 8 are formed. Since the mobility of minority carrier which is injected from the emitter and reaches the collector layer is alleviated remarkably in the degree disturbed by the potential barrier produced in the region 3, sufficiently large DC current gain can be obtained.

Filed: 1994-09-13
Abstract: PURPOSE: To minimize harmful matter during warmup by supplying an air/fuel mixture to a catalytic conversion system, and determining the light-off behavior of the catalytic conversion system in accordance with the influence of supply of the air/fuel mixture on the light-off behavior. CONSTITUTION: A first oxygen sensor 214, a catalytic conversion system 216 having a temperature sensor 217, and a second oxygen sensor 218 are arranged in an exhaust pipe 204. An air/fuel mixture consisting of air and unburnt fuel is supplied to the catalytic conversion system 216. An instantaneous temperature of the light-off region of the catalytic conversion system 216 is detected by means of the temperature sensor 217 and stored. Determination is made as to whether or not the difference between the instantaneous temperature stored and an initial temperature is greater than a threshold read from a read-only memory.  If the former is greater than the latter, then the light-off region temperature is elevated sufficiently to allow the catalytic conversion system 216 to function smoothly; if the former is not greater than the latter, the instantaneous temperature is not sufficiently elevated, so that the catalytic conversion system 216 can be determined as not functioning and light-off behavior can be monitored.
