Title: Manufacture of photoelectric integrated circuit
Inventor: IMOTO YASUMASA
IPC: H01L27/15
Filed: 1989-06-27
Abstract: PURPOSE:To obtain a high-speed photoelectric integrated circuit by forming a optical device layer which is thinner than the depth of a recess part on a substrate wherein the recess part is formed, thereafter filling the recess part with photoresist, performing etching, and embedding the optical device layer flatly. CONSTITUTION:An optical device layer 3 whose thickness is thinner that the depth of a recess part 1 is formed on a semi-insulating InP substrate 2 in which the recess part 1 is formed. The recess part 1 is flatly filled with a positive-type novolak based photoresist 4. Then, the optical device layer 3 and the photoresist 4 are etched at an approximately equal speed by ion-beam etching method. An electronic device layer is formed on the InP substrate 2 wherein the optical device layer 3 is flatly embedded. In this way, the optical device layer 3 can be flatly embedded layer 3, and a high-speed photoelectric integrated circuit can be obtained at a high yield rate.

Title: Scram valve for hydraulic pressure control unit
Inventor: TAKEGAWA TORU
IPC: G21C7/16
Filed: 1988-07-04
Abstract: PURPOSE:To improve scram performance by forming spherically a shape of the tip of a valve body with respect to an air-operated scram valve of a hydraulic pressure control unit of a control rod driving hydraulic system of a boiling water nuclear reactor. CONSTITUTION:A bonnet 14 is attached to the upper end part of a body 10 of a scram valve, and a valve chamber 15 is formed between the bonnet and the body 10. In the valve chamber 15, a seat part is formed by inserting a valve body 30 formed integrally with a valve rod 17. Also, the lower face of the valve body is formed spherically. At the time of scram, the valve body moves to a back seat surface 19a from a seat surface 16a and an inlet port 11 and an outlet port 12 are allowed to communicate with each other. At this case, a fluid 13 indicated with an arrow passes through a gap between the lower end of the valve body 30 and the seat surface 16a from the inlet port 11 and flows to the outlet port 12, and since the bottom face of the valve body 30 is spherical, turbulence caused by the flow of the fluid 13 can be released, and the scram performance can be improved.

Title: Duplex retarder
Inventor: MAEDA MASAHIRO
IPC: F16D65/18
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To achieve moderate braking stop having a slight shock, and retain certain stationary by a large braking force after rotation is stopped, by immediately shutting off the operating coil current of a first electromagnetic brake after the stop command to a braked rotating machine, and momentarily retaining the operating coil current of a second electromagnetic brake. SOLUTION: When a command to stop a motor is transmitted, the exciting current of an electromagnetic brake 10 is immediately made to be zero and braking having a little delay time starts to operate, however, effect of braking force is loose because of residual magnetism, and the rotational speed of the motor is gradually lowered, and finally stopped. Although electric power supply to an electromagnetic brake 50 is disconnected afterward, momentary current is continued to flow by the self-holding energy of the electromagnetic brake 50 and the residual energy of the motor while rotating, and timing when the braking force of the electromagnetic brake 50 is exhibited is further delayed, thereby braking force can be generated for the first time after a while after the motor is stopped.  After this time, the motor braking force is kept applying to both electromagnetic brakes 10 and 50, to retain the motor in its static condition.

Abstract: PURPOSE:To obtain the subject high-purity compound with a low ester value at a high conversion rate by oxidizing cyclohexane, esterifying the resultant carboxylic acid compound, separating and purifying the carboxylic acid ester compound, bringing the obtained compound into contact with a basic solid substance and hydrogenating the ester having a low acid value. CONSTITUTION:Cyclohexane is oxidized to provide a carboxylic acid compound, which is then esterified with alcohols, separated and purified to afford a liquid mixture of esterified substances having a high acid value. The obtained liquid mixture is subsequently brought into contact with a basic solid substance to regulate the acid value (AV value) thereof to <=0.8mgKOH/g. The resultant liquid mixture of the esterified substances having a low acid value is then hydrogenated in the presence of a hydrogenation catalyst to industrially and advantageously afford high-purity 1,6-hexanediol, having <=30mg KOH/g ester value (EV value) and useful for producing polyesters, curing agents, etc., at a conversion rate as high as >=95%. Furthermore, the unreacted basic solid substance can be readily removed from the above-mentioned reaction solution by simple operation due to sparing solubility thereof in the hydrogenation reaction solution.

Abstract: PURPOSE: To prevent the slackness of sheets by separately driving rolls at the outlet side at the speed same as the circumferential speed or slightly faster than the circumferential speed of rolls at the inlet side.  
     CONSTITUTION: A variable speed motor 16 for driving throttling rolls is mounted apart from a drive motor 6, and a sprocket 17 and a sprocket 13 are connected by a chain 18. A chain 20 transmitting the revolution of the drive motor 6 to the shafts of brush rolls 2 through the shafts of pinch rolls 1 is stretched to the sprocket 13. Consequently, the throttling rolls 3 can separately by turned through the sprockets 13, 17 and the chain 18 by means of the motor 16 for drive at the speed same the as the circumferential speed or at the speed slightly faster than the circumferential speed of the pinch rolls 1 rotated by means of the drive motor 6. Thus, even when a nonwaven fabric of the throttling rolls 3 is worn, the circumferential speed of the throttling rolls 3 is accelerated by means of the motor 16 for drive, and is not made slower than the circumferential speed of the pinch rolls 1 at all times.
