Title: Monolithic photocoupler
Inventor: SUTSURE GOORANSON
IPC: H01L31/12
Filed: 1988-12-01
Abstract: PURPOSE: To provide a monolithic photocoupler which transmits a remarkably small quantity of disturbing signals by providing a conductive layer which is formed on the surface of a substrate between two optical parts in an integrated state and a connecting device for grounding the conductive layer. CONSTITUTION: A metallic layer 4 connected to an earth 6 through a conductor 5 is formed on the surface of a substrate 1. The layer 4 is formed by using the same technique as that used for forming two optical parts A and B. Namely, the layer 4 can be formed in the same manufacturing step together with metallic layers A4, A5, B4, and B5. The layer 4 executes two functions. The layer 4 effectively absorbs all disturbing current components flowing between the optical parts A and B. The layer 4 also works as a shielding body and remarkably reduces the capacitive transmission of disturbing signals between the parts A and B through the surrounding environment. The layer 4 also remarkably reduces the resistive transmission of the disturbing signals between the parts A and B through the substrate 1.

Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To improve safety by installing a cover member freely moved towards the front of a cutter along the top plate of an adit to an excavator with the cutter. SOLUTION: The upper plate of the upper frame 26 of a front-section frame 23 is formed in a two-ply shape while an external plate in the upper plate is brought to a slidable state to an internal plate and a cover member 95 is prepared.

Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To reduce dispersion of the response time from issue of a shift command till start of the effective shifting by compensating the difference between individual items of products. SOLUTION: A duty command value for a solenoid 16b for controlling the clutch pressure is issued so as to decrease in such a rate as complying with the second = order function of the time as shown in the given equation. Thereby the target liquid pressure also decreases in the rate complying with the second-order function. Duty command value-initial value - a.t<2> , where (a) is factor of second-order function, and (t) is time. That is, an oil pressure command value as control command value (duty command value) is issued so that a target oil pressure as given by the second-order curve shown in Fig. 7 is obtained. Because the gradient of the graph indicating the target oil pressure is steep just before starting of the effective shifting, dispersion in the start of the effective shifting can be reduced whether the oil pressure lies at a high level or a low.
