Title: Die for molding resin sealing part of electronic component
Inventor: TAKEISHI ATSUSHI
IPC: B29C45/14
Filed: 1991-05-27
Abstract: PURPOSE:To prevent failure in molding when the resin sealing part of a diode is transfer-molded by the use of epoxy resin. CONSTITUTION:A resin sealing part 2 has a truncated cone shape part 4 in the end part of a columnar shape part 3. A gate 26 formed into a tapered shape toward a cavity is opened to the truncated cone shape part A. Moreover, the axial direction obliquely intersects for the generatrix direction of the surface of the truncated cone shape part 4. The shape of the tip part of the cavity side of the gate 26 is set so that thickness is nearly specified along the generatrix direction of the surface of the truncated cone shape part 4. Thereby, flow of resin to the cavity from the gate 26 is smoothened.

Title: Copper alloy with superior corrosion resistance
Inventor: KAWAUCHI SUSUMU
IPC: C22C9/01
Filed: 1983-07-05
Abstract: PURPOSE:To obtain a Cu alloy with high strength and superior corrosion resistance by preparing a specified composition consisting of Al, on or more among Fe, Ni, Cr and Co, and Cu. CONSTITUTION:This Cu alloy with high strength and superior corrosion resistance consists of, by weight, 0.05-1.5% Al, 0.005-1.0% in total of one or more among Fe, Ni, Cr and Co, and the balance Cu with accompanying inevitable impurities or further contains <=0.5% Zn and/or <=0.1% P. The Cu alloy is suitable for use as a material for a radiator for a car, especially for the fins of the radiator. Among said components, Al improves the corrosion resistance, yet >1.5% Al reduces the heat conductivity and workability. Fe, Ni, Cr and Co improve the corrosion resistance and strength, yet when the total amount of them exceeds 1.0%, the heat conductivity is reduced. Zn improves the castability, P acts as a deoxidizer, and they are added as required.

IPC: G06F11/22
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To evaluate a fault without any trouble even if a load is not concentrated on some package like a master-side package and a fault occurs to a package like that. SOLUTION: In addition to a 1st package 1021 , other packages are connected to an alarm notification bus 101 and each of them detects an internal fault by a fault detection part 114 and sends fault information out of a fault information transmission part 112 to the alarm notification bus 101. A fault information reception part 113 receives the fault information sent from itself or another package through the alarm notification bus 101 and sends it to a fault evaluation part 115 together with internal fault information to evaluate the fault. When it is judged that a local package 1021 has got out of order, a fault lamp 1161 is turned on to notify a service engineer. In this system, the individual packages 102 evaluate faults, so problems resulting from centralized processing can be solved.

IPC: G01B11/08
Filed: 1978-10-04
Abstract: PURPOSE:To prevent the mis-detection of record size due to wow and flutter, by constituting the circuit with logic IC and converting the serial record size signal into parallel signal. CONSTITUTION:When the photo electric conversion signal 302 is inputted and the level is changed at the time point a in Fig. from L to H, the switch 310-a is closed, and the counter 303 receives the turn control signal 301 and starts the count from the time point e. Further, the counter 304 starts count from the time point b. When the counter 303 counts the number of pulses N taking one revolution of the turntable as one period, it is self-reset and the signal of the output 306 of the counter 304 is at latch output. Simultaneously, the counter 304 is reset. Since the counter start time of the counters 304 and 303 has time difference by almost the pulse width of photo electric conversion pulse of the serial electric signal 302, the malfunction to the period variation of turntable is avoided.

Abstract: PROBLEM TO BE SOLVED: To make it possible to lessen the turn-off power loss of a semiconductor device, which is a power loss at a turn-off time of the device, by a method wherein an impurity diffusion depth to turn to the first main surface side of the second region, which turns to a first semiconductor layer, of a third semiconductor layer is formed deeper than that to turn to the first main surface side of the first region, which turns to a second semiconductor layer, of the third semiconductor layer. SOLUTION: In the structure of an IGBT, an n<+> layer 3 of an impurity concentration higher than that of an n-type buffer layer 2 is formed at a region held between the layer 2 and a p-type collector layer 4. An impurity diffusion depth to turn to the first main surface, which is located under the region formed with this layer 3, of the first region 4a of the layer 4 is formed so as to be shallower than that to turn to the first main surface, on which the layer 3 is not formed, of the second region 4b of the layer 4. As a result, a hole injection is not inhibited at the region, where the layers 4 and 2 come into contact with each other, and an inhibition of a hole injection becomes possible at the region, where the layer 3 interposes between the layers 4 and 2.
