Title: Temperature control method of semiconductor laser
Inventor: SHIBATA ISAMU
IPC: H01S5/042
Filed: 1984-06-19
Abstract: PURPOSE:To enable to bring the temperature rapidly to approx. the setting temperature, by a method wherein when the temperature of a semiconductor laser is largely different from the setting temperature, a Peltier element which heats or cools the laser is sent and driven at the 100% duty. CONSTITUTION:The temperature sensitive element outputs from a thermistor 14 are compared with a lamp wave form L at a comparator 18. When the temperature sensitive output becomes higher than the setting value F, a photo-coupler 38 is connected, the reference value of a comparator 12 becomes -V lower than the lowest value of a lamp wave form L. As to the output of the comparator 12, the logical value of which becomes always 1.0, and as to the output of the comparator 18, the logical value becomes always 0. The outputs of inverters 28, 30 becoming 1.0 by the logical value, the cooling current I1 is applied at the duty 100%, and the laser is cooled continuously. When the temperature sensitive output is lower than the set value G, a photo-coupler 40 is connected, and the reference value E of the comparator 12 becomes +V, a heating current I2 is applied at the duty 100% to the Peltier element 32.

Abstract: PURPOSE:To operate switching operation safely, by a method wherein ignition pulses are given in a prearranged order by an output current detecting circuit and an output voltage detecting circuit when a regular-side thyristor bridge is OFF and a reversal-side thyristor bridge is ON. CONSTITUTION:An output current detecting circuit 6 which consists of a current detector 7 and a current polarity detector 8, an output voltage detecting circuit 12 and an ignition control circuit 9 which controls current transfer phase of thyristor bridges 3A, 3B are attached to an electric power converter which consists of an AC source and the thyristor bridges 3A, 3B connected to the source. In order to transfer current from the bridge 3A to 3B, the ignition pulse of the bridge 3A is OFF when the current of 3A is nearly zero and the OFF stage of 3A is detected by detecting that the phase is such that the potential applied to the element being ignited lastly is negative and that the regular potential is applied to the bridge 3B and then the bridge 3B is made ON. Thus the switching can be operated safely and securely without a period of zero current and without generating a short circuit loop.

Title: Manufacture of color picture tube
Inventor: OKUDA HIROSHI
IPC: B05D7/24
Filed: 1986-05-29
Abstract: PURPOSE:To reduce a blowoff gas quantity as well as to aim at the promotion of long service life, by using such one made of burning oxy-bismuth carbonate as bismuth oxide, in case of a color picture tube which installs a film containing the bismuth oxide and water glass on a shadow mask. CONSTITUTION:Bismuth oxide is produced in the following process that metallic bismuth of original material is melted and, after being dissolved in nitride acid, it is made to react with ammonium carbonate, and the obtained oxy- bismuth carbonate is burned for several hours at a proper temperature of 500-600 deg.C. The bismuth oxide obtained in this method is sufficiently usable without a comminution process such as ball mill or the like. And, in case of forming it into a grain of less than 1mum in average grain size, the shortening of considerable time for the end is possible and, what is more, adsorption gas becoming a main factor of impurities and blowoff gas at this comminution process is also reduced. In this connection, a compounding ratio of the bismuth oxide and water glass sets this water glass to 0.2-0.4 against the bismuth oxide 1 (wt. part), and further ordinary water 0.6-0.8 is blended. With this constitution, a gas blowoff quantity is reduced so that a life characteristic is sharply improved.

Title: Chip part
Inventor: FUKUOKA AKIO
IPC: H05K3/34
Filed: 1989-05-19
Abstract: PURPOSE:To prevent both oxidation of solder and formation of a compound film, and to contrive improvement in solderability by a method wherein maximum oil component of 0.1% is contained in the slight gap left in a terminal electrode part. CONSTITUTION:The third layer of solder plating 7 of a terminal electrode part 4 is dissolved by heated oil, and an oil component 8 is contained in the microscopic gap of the third layer solder. When the oil component 8 is contained in the solder layer 7 as above-mentioned, the oxidation of metal surface can be prevented, also the formation of a compound film due to the reaction of the metal surface, which comes in contact with gas, with gas can be prevented, and at the same time, the oil which is mainly composed of triglyceride of saturated fatty acid, reduces the degree of faulty soldering by showing the effect of flux itself. Besides, as a bad influence is given to the finishing condition of soldering when excess oil is contained, the desirable oil content is 0.1% at the maximum, and the excessively adhered oil component is removed by washing. As a result, the generation of insufficient strength of soldering can be prevented, and the stabilization of quality of soldering can be achieved.
