Title: Preparation of light emission semiconductor device
Inventor: YANO KENJI
IPC: H01L21/208
Filed: 1979-06-11
Abstract: PURPOSE:To improve the efficiency of the light emission by a method wherein a reverse conduction type layer is grown on a single conduction type compound semiconductor substrate in a liquid phase, and only the layer in the first stage of the growth, wherein the X value and thickness can easily be controlled, is used as the light emission region and the grown layer after that is used as a mere supporter layer. CONSTITUTION:When the P-type Ga1-XAlXAs layer 22 is grown on the N-type GaAs substrate 21 in a liquid phase, a starting point of the temperature drop of the melt is regulated to 900 deg.C and X value to about 0.3 to grow to a layer of -5mum thickness. Next the melt is replaced, the N-type Ga1-XAlX layer 23 of -50mum thickness is grown, temperature of the melt is regulated to 900 deg.C, X value to 0.3, and then temperature is gradually reduced so that the X value may become 0.1. In this way, the layers 22, 23 for the light emission regions are obtained, and after this, the N-type Ga1-XAlXAs layer 24 that grows afterwards a mere electrode contact part is grown to the -100mum thickness. Next the substrate 21 is removed from the element by the etching method, the layer 22 is coated with SiO2 film 25, and the light emission window 25A is opened in the film 25.

Title: Electric discharge machining condition detector
Inventor: SUZUKI YASUO
IPC: B23H1/02
Filed: 1981-05-18
Abstract: PURPOSE:To identify the discharge condition quantitatively  and precisely by applying a high voltage pulse charged in a condenser to a work gap, comparing the gap voltage with a multitude of reference voltages, and detecting an abrupt descent of the gap voltage. CONSTITUTION:A high voltage pulse from a pulse power source 1 is charged in a condenser 2, and is further applied between an electrode 3 and a work 4 for performing the discharge work. The work gap voltage is divided by means of resistors, and is detected as a voltage E0. Non-discharge condition detection pulse is output and integrated in a condenser 31 when the gap voltage E0 is higher than a reference voltage E1, and when the voltage E0 is higher than a voltage E2 but no discharge occurs (between CL1 and CL3). A normal discharge is detected by an abrupt descent of the voltage E0 from the condition of E0> E2, and a detection pulse is integrated in a condenser 32. An abnormal arc discharge V4 and a short circuit CL7 are detected by comparing the voltage E0 with the voltage E4, and are integrated in condensers 33, 34 respectively.

Title: Ph adjusting method for waste water
Inventor: TAKEGAHARA KAZUSHI
IPC: G01N27/38
Filed: 1978-06-20
Abstract: PURPOSE: To secure the insulating property of a pH detecting electrode and to enhance waste water treating efficiency as well as to prevent contaminants from attaching to the outside of the electrode, in pH adjustment of waste water, by placing the electrode outside a pH adjusting vessel.  
     CONSTITUTION: In treatment of waste water by an activated sludge method, a flocculation sedimentation method, a flocculation floating method, or the like, the waste water is adjusted to a pH value fit to the treatment. Waste water charged into pH adjusting vessel 10 is fed to pH detecting electrode part 16' outside vessel 10 with pump 12 to detect the pH value, and it is returned to vessel 10 to form a circulating system. The detected pH value is sent to indicator 18, and according to a response from indicator 18 magnet valve 22 opens to feed a pH adjusting soln. from tank 20 into vessel 10, thus adjusting the waste water to a desired pH value. Since the speed of the waste water flowing to part 16' is high, no contaminants attach to the outside of the electrode. The electrode is not dipped in waste water, so the insulating property is not deteriorated, and waste water is treated stably.

Abstract: PURPOSE:To appropriately regulate the hight a vehicle during change in the attitude of a vehicle body, by holding the delay operation of a hight control delaying means when the vehicle body changes its attitude. CONSTITUTION:When vehicle hight signals 12a-12d are delivered to a microcomputer 20 from a steering angle sensor 13, an accelerator opening degree sensor 14, a brake switch 15 and a multiplexer 21, an averaged vehicle level, a turning condition, an accelerating condition and a vehicle vertical vibration condition are judged in accordance with a predetermined procedure, and judgment is made upon the changing condition of the vehicle attitude to detect the presence of change in the vehicle attitude. Further, when the attitude of the vehicle body changes, the reset and addition of a counter for delaying the hight control are both stopped to hold that condition. Accordingly, the vehicle hight is retained until completion of the vehicle attitude changing condition. After the completion of the vehicle attitude change, the delaying operation is restarted. With this arrangement, the vehicle hight may be appropriately controlled in the vehicle attitude changing condition.

In this case, when a pressure governor G which is actually driving synchronously air compressor CM1 and CM2 out of a plurality of pressure governors G1, G2..., fails to have said output contact (No.1 contact) RY1a continued being in an ON condition, and when air pressure is increased upto the set value for over pressure, No.2 contact RY2a is OFF. Then the air compressor CM is suspended, and furthermore a synchronous control since then is assumed by the remaining normal pressure governor G. Accordingly, the burning of a motor, an increase in pressure of delivery air, and the degrading in dehumidifying performance can be prevented.
