Title: Optical pickup head
Inventor: SATO CHIAKI
IPC: G02B26/10
Filed: 1985-08-09
Abstract: PURPOSE:To produce easily an optical pickup head with reduction of the cost and in a compact and light-weight design and then to attain the access and tracking at a high speed, by using a semiconductor laser having a function to give deflection to the output light to a light source. CONSTITUTION:A semiconductor laser i.e., a beam scanning laser BSL20 having a function to give deflection to the output light is obtained by making positive use of a gain waveguide mechanism. That is, the gains are distributed symmetrically on the basis of the center of an active layer and within this layer of a normal gain waveguide type semiconductor laser since the current injecting electrodes are formed evenly on the active layer. While the electrode is divided into two parts on the active layer in the case of the BSL20. Then it is possible to inject the current to said a pair of electrodes independently of each other and therefore an asymmetrical gain distribution is secured within the active layer. Then the asymmetrical gain distribution is secured in an active area 31 of an active layer 23 by changing the ratio between the injected currents I1 and I2.

Title: Internal chill body
Inventor: YAMAMOTO YOSHIAKI
IPC: B22D19/00
Filed: 1988-07-13
Abstract: PURPOSE:To improve the thermal impact resistance of the internal chill body and to facilitate casting by forming an inside layer of ceramics, forming a metallic layer on the outside layer and interposing a ceramics fiber structural body between the inside and outside layers. CONSTITUTION:The ceramics fiber structural body is disposed to the outer periphery of the ceramics to be internally chilled and a molten metal heated to a high temp. of 1400 deg.C, etc., is poured into a casting mold. The molten metal in the casting mold comes into contact with the ceramics fiber structural body and a large quantity of heat moves to generate thermal impact but the ceramics fibers have heat resistance and are small in the coefft. of thermal expansion; therefore, the thermal stress is suppressed and the internal chill body which withstands the thermal impact is formed. The inside layer, the structural body and the outside layer are hermetically held by the difference in the coefft. of thermal expansion at the time of casting. The thermal impact resistance of the internal chill body is improved and the production is facilitated.

IPC: H01L23/52
Filed: 1982-10-08
Abstract: PURPOSE:To enable to reduce the size of a semiconductor chip by using a semiconductor substrate P-N junction fuse for a current path when a current fusion type fuse is melted. CONSTITUTION:A fuse 4, i.e., C formed of polysilicon is formed on the surface of a field insulating film 2. One end of this fuse 4 is connected via an aluminum wire 5 to a semiconductor region 3, and the other end is connected to a pad 6 formed of aluminum, i.e., (d). The operation of melting the fuse (c) is performed by using as one end of the current path the pad (a) or the substrate (e) itself becoming the same potential as a semiconductor substrate (l) and flowing a melting current to the pad (d) through a diode (b). At this time, a probe needle is contacted with the pad (d), and a current is flowed. Whether the fuse (c) is melted or not is identified by identifying whether the voltage is conducted between both electrodes or not. Since this circuit can be formed of one aluminum pad for one fuse, the area of the chip can be reduced.

Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To detect the integrity of a buffer spring part by moving a hollow piston with a specific thrust pressure and comparing the stop position with a reference position determined in advance. SOLUTION: A hollow piston 17 is connected to the end part of a control rod 6 and performs insertion and withdrawal of the control rod 6. Two kinds of buffer springs 24 and 26 with different spring constants for mitigating the collision of the piston 17 are arranged at the end in the moving direction of the piston 17. The piston 17 is moved with a specific thrust pressure against the buffer spring 24 with a smaller spring constant until it stops and the stop position is compared with a reference position determined in advance. From this difference, the integrity of the buffer spring 26 with a larger spring constant is detected. In this manner, non-functioning state of the buffer springs 24 and 26, loss-of-elasticity state in other words, can be detected without removing the control rod drive device 5 from the reactor pressure vessel 1 and overhauling.
