IPC: H01S5/00
Filed: 1983-10-17
Abstract: PURPOSE:To ensure high geographical accuracy and easy assembly by a method wherein residual stress after an assembly process is mitigated by integrating a submount and a monitoring photoreceiving element into a single body. CONSTITUTION:Portions of an N<+> layer 6c and Si substrate 6a supporting a semiconductor laser chip 1 mitigate the stress generated on the chip 1 by a heat- radiating block 3, and serve as a submount.

The photoreceiving element is so constructed that photoelectric current generated across the P-N junction produced along the area between the layer 6c anc P type epitaxial layer 6b is detected at a terminal connected to an electrode 6f and to the block 3. In such a construction, the submount 6 and a photoreceiving element can easily be unified into a single body.
Patent JP-H0360185-A (JP)
Title: Manufacture of ceramic substrate with copper wiring
Inventor: IIZUKA TOMIO
IPC: H01L23/12
Filed: 1989-07-28
Abstract: PURPOSE:To prevent local abnormal growth of a platen section produced when a coating film of a metal, such as nickel, etc., other than copper is formed by an electroplating method so as to improve the reliability or yield of the title substrate by adding an extremely small quantity of a rare earth element to highly pure copper used as the source of vapor deposition. CONSTITUTION:An alloy composed of >=99.999% pure copper with 4-30ppm of a rare earth element added is used as the source of vapor deposition. When copper of <99.999% in purity is used, whisker or fin-like abnormal growth occurs at the time of plating nickel 5, etc. When copper of >=99.999% in purity is used, the whisker-like abnormal growth can be eliminated almost completely even when the rare earth element is not added, but a little possibility of occurring the fin-like abnormal growth still exists. However, when the rare earth element is added by 4-30ppm, the occurrence of the fin-like abnormal growth can be suppressed. Addition of the rare earth element in excess of 30ppm is not desirable, since the hardness of a wiring film becomes higher and the wire- bondability becomes worse. Since the surface of ceramic substrates 1 is rough as compared with that of other substrates, this effect is remarkable.

Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To transfer an ATM (asynchronous transfer mode) cell efficiently via a unidirectional path by inserting a transmission signal of a transmission line to an adjacent terminal equipment via its path and allowing the adjacent terminal equipment to receive the incoming signal via the transmission line. SOLUTION: An STS management section 70 receives an incoming signal from an 0/E interface 50 in the incoming direction and designates a path for an STS-MC to an ATM cell management section 90. The STS management section 70 receives an STS-Mc subject to ATM mapping received from an ATM cell management section 90 and an input from a non-ATM payload management section 80 and designates a path. The STS management section 70 conducts unidirectional line exchange ring protection or the like for the non- ATM cell or the like under the control of an STS protection control section 115. Since a protection switching in the node A is unidirectional, the STS management section 70 designates a path for the transmission signal on an output line 54 at all times and receives an incoming traffic from the line 53 at all times.

Title: Disk brake device
Inventor: GOMI MIKIO
IPC: F16D65/18
Filed: 1992-07-23
Abstract: PURPOSE:To prevent drag of a brake by providing a contact force increasing face on the outside in the radial direction of a piston contact part of a retrac tion ring for receiving force by fluid pressure in contact with brake fluid in the direction of the piston contact part. CONSTITUTION:A notch 91 is provided over the entire circumference of a face in contact with brake fluid of a retraction ring 9, filled with the brake fluid, and a contact force increasing face 92 is formed. When fluid pressure is generated in the brake fluid, the fluid pressure acts on an opening face of the notch 91, a downward force acts on the contact force increasing face 92, and the inner circumference of the ring 9 is reduced. By this, a contact force of the ring 9 to a piston 6 of a piston contact part 93 is increased, and the ring 9 is deformed with sliding of the piston 6 without slipping on it. When the fluid pressure is reduced, the piston 6 is returned to the original position by an elastic force of the deformed ring 9, and as brake friction materials 2 and 3 are provided with a spring for separating it from a disk rotor 1, drag of the brake is prevented.

Title: System for continuously executing and processing program in case of occurrence of exception
Inventor: AKUSAWA HARUMI
IPC: G06F11/34
Filed: 1986-08-22
Abstract: PURPOSE:To eliminate the reputation of analysis and correction by previously registering continuous points before exceptions occur, recording exceptions in case they occur and continuing the operation as much as possible. CONSTITUTION:When a system 100 rises, a damp command specification means 1 starts. In case exceptions occur at the start point of a program, a processing continuous point registration means 2 sets the processing program as a supervisor output program. Afterwards, the name of the program and a return address are registered in a continous point storage area 3. If exceptions happen under the execution of programs, a damp command analysis means 5 analyzes the contents of the specified damp command. An exception recording means 6 judges whether the exceptions of the program developing exceptions have already been recorded or not in an exception recording area 7. If so, generation rate is incremented, and the record concerned in the recording area 7 is updated. If not, a new record is recorded in the recording area 7 where the name of the program concerned, its offset, the type of the exceptions and the geration rate are '1'.
