Abstract: PURPOSE:To obtain excellent characteristics of an element and to improve the manufacturing yield rate of the element, by providing an excellent P-N junction, which is formed by a semiconductor that surrounds an active layer light guide. CONSTITUTION:A wafer having a multilayer film structure, wherein the following layers are sequentially laminated on an N type InP substrate 1 having the surface direction of (001), is manufactured: an N type InP buffer layer 2 having the impurity concentration of 2X10<17>cm<-3>; an InGaAsP active layer 3 of a composition having the light emitting wavelength of 1.3mum; and a P type InP clad layer 4 in which Cd is used as impurities. Then, two grooves 90 and 91, which are in parallel with <110>, are formed, with a photoresist 80 as a mask. A mesa stripe 20 having the width of about 2mum is formed between the two grooves. After the photoresist 80 is removed, the second LPE growth is performed. Then, a P type current blocking layer 8 is laminated. Thereafter, N type InP current confining layer 9 is laminated on a flat part to the film thickness of about 0.5mum, but is not laminated on the upper part of the mesa stripe 20. Then, a P type InP embedded layer 10 is laminated on the flat part to the thickness of about 2mum including the upper part on the mesa stripe 20 so that the entire body is embedded and grown. Finally, a P type InGaAsP electrode forming layer 11 is laminated on the flat part to the film thickness of about 1mum.

Title: Method and device for treating molten metal
Inventor: KISHIMOTO YASUO
IPC: C22B9/10
Filed: 1986-08-06
Abstract: PURPOSE:To improve the reaction efficiency of a flux in refining of a molten metal by imparting rotating force to the liquid column of the molten metal in one rising part of a bent tubular vessel and adding a flux to the other rising part. CONSTITUTION:The molten metal 3 is housed into the bent tubular vessel having the plural rising parts 1, 1'. The flux 4 which is the refining agent is added into the bath of the molten metal 3 from one rising part 1 through an injection lance 6. The rotation is forced by a rotating magnetic field generator to the liquid column of the molten metal 3 occupying the other driving rising part 1'. The spiral swirling flow of the bath of the molten metal 3 generated by such rotating magnetic field induces the spiral stirring flow of the molten metal 3 bath in the rising part 1. The above-mentioned flux 4 and the slag 7 derived therefrom are thereby included into the molten metal 3 bath and is penetrated and moved toward the driving rising part 1', by which the contact thereof with the molten metal 3 is accelerated and the refining is executed with high reaction efficiency.

Title: Information processing system
Inventor: SAKAI YOSHIYUKI
IPC: G06F1/00
Filed: 1985-08-21
Abstract: PURPOSE:To minimize power consumption by generating a power source supply command signal even due to the supply of a desired processing signal from a central control system, outputting the 2nd electric power from a power source part and attaining a desired action due to the supply to the 2nd electric power according to the processing signal. CONSTITUTION:When a switch 29 is 'on', the central control system 21 from which the electric power P21 is supplied acts processing, and a signal 15 supplies the processed result to a system unit 13. When the signal 15 is supplied, the system unit 13 generates a power source supply command signal 17, and supplies it to the power source part 11. In correspondence to the command signal 17, the power source part 11 generates the electric power P13 to supply it to the system unit 13, which attains an action state, and can display the processed result expressed by the signal 15. In the system unit 13 a circuit which detects whether the signal 15 is present or not and generates the command signal 17 always acts, and electric power to said circuit is always supplied independently. Thus power consumption can be minimized.

Title: High impedance preventing circuit
Inventor: YAMAGUCHI HISASHI
IPC: H03K19/0175
Filed: 1987-07-22
Abstract: PURPOSE:To improve the flexibility by holding an input signal level of an inverter buffer circuit just before when an output impedance of a tri-state buffer is high so as to give the level to the input terminal of the titled circuit. CONSTITUTION:When the output impedance of the tri-state buffers 1-4 is all high independently of the number, an input level hold circuit 9 holds the input signal level of the inverter buffer circuit 10 just before and gives it to the input terminal of the inverter buffer circuit 10 thereby keeping the input level of the inverter buffer circuit 10 to a low or a high level. Then either of P, N-channel TRs 7, 8 of the inverter buffer circuit 10 is turned on. Thus, it is prevented that the drive impedance to a logic integrated circuit 12 is a high impedance.

Title: Solar time switch
Inventor: TANAKA TOSHIAKI
IPC: H05B37/02
Filed: 1983-09-30
Abstract: PURPOSE:To save electric power energy and prevent such trouble that an illuminating load is turned off in the nighttime before dawn on a skip day by preventing the illuminating load from being turned on a skip day such as a holiday. CONSTITUTION:A skip day setting part 5 sets holidays on which the illuminating load 4 is not turned on, and a turn-on inhibiting means 6 inhibits the illuminating load 4 from being turned on from the sunrise to the dawn of a skip date. The illuminating load 4 is not turned on the holidays set at the skip day setting part 5 to save electric energy, and such trouble that the illuminating load 4 is turned off suddenly in the nighttime before a skip day is evaded. Namely, days on the calendar are changed in the midnight, but when the illuinating load 4 is turned off at 24:00, the illuminating is not maintained although there are still overtime workers or night workers, so the period before the dwan of a holiday is regarded as the extension of the last day to keep the illuminating load 4 on.

Title: Printing device
Inventor: KOIKE MITSUHITO
IPC: B41J2/245
Filed: 1987-07-22
Abstract: PURPOSE:To facilitate the adjustment of printing timings and to make a device small, by a method wherein a plurality of line printing heads are staggered so as to alternate with each other in position and direction in a sub-scanning direction. CONSTITUTION:Line thermal heads 20a-20d are a planar head. The line thermal heads 20a and 20c on the front line are elastically installed so as to be pressed down against platen rollers 10a and 10c by a predetermined pressure with printing parts disposed backwards. The line thermal heads 20b and 20d on the rear line are elastically installed so as to be pressed down against platen rollers 10b and 10d by a predetermined pressure with printing parts disposed frontwards. As a result, the line thermal heads 20a-20d are staggered so as to alternate with each other in position and direction in a sub-scanning direction. In this manner, a shortage in printing can be prevented between the line thermal heads 20a-20d, and the distance between the line thermal heads 20a-20d in the sub-scanning direction can be made smaller to facilitate the adjustment of printing timings of the line thermal heads 20a-20d.

Title: Multiple ink jet recording device
Inventor: OBARA KAZUKI
IPC: B41J2/15
Filed: 1980-12-25
Abstract: PURPOSE:To perform high speed recording with high quality without the difference in arriving times on recording paper, by providing a plurality of supply holes at the opposite positions with respect to jetting holes at both ends in the line direction, and supplying ink to an ink chamber from said supply holes. CONSTITUTION:The ink is supplied to the ink chamber 31 in a nozzle 3 from the supply holes 33a and 33b at both ends by using two ink pipes 2a and 2b from an ink supply system 1. Of a plurality of the jet holes 32a-32e, the jet holes 32a and 32e at both ends of the line direction are close to the supply holes 33a and 33b, and the external hole ends of the supply holes 33a and 33b are contacted with the wall surface of the ink chamber 31. Therefore a layered stream is formed on the wall surface of the ink chamber 31, and turbulent streams are formed in the vicinity of the center of the ink chamber 31. The speed distribution of the ink jet streams at the jet holes 32a-32e is such that the speed on both sides is faster than that in the center. However, the speed of the ink drops at both ends becomes slower due to the resistance of the air during flight, and the ink arrives at the recording paper 11 at an approximately equal speed as a whole. Therefore, the excellent printing quality can be obtained even though head feeding is performed at a high speed.
