Title: Distributed feedback type semiconductor laser and distributed reflection type semiconductor laser
Inventor: FUJII HIROAKI
IPC: H01S5/00
Filed: 1988-09-20
Abstract: PURPOSE:To make the diffraction efficiency of a laser constant irrespective of a machined shape, improve uniformity and reproducibility, and manufacture it easily by forming steps of fixed cycle reflectivity as the result of the absence of order of a multi-quantum well structure in an axial direction of a resonator. CONSTITUTION:An active layer 1 and a clad layer 3 composed of a clad layer 2 and a multi-quantum well structure are grown on a substrate 7. The GaAs well layer of the active layer 1 is made sufficiently thick to a degree that it is not quantized. The average composition of the active layer after the absence of order is set so that it becomes Al0.2Ga0.8As. Next, Si ion implantation of linear repetitive pattern is performed. This Si implantation area 11 is made parallel to the resonator surface and distribution reflectivity is given to light running in an axial direction of the resonator. The repetition cycle of the area 11 forms a fourth-order diffraction grating to the oscillation wavelength of laser. Next, the layer 3 is etched and a clad layer 4 and a cap layer 6 are grown. Lastly, a p electrode 8 and an n electrode 9 are formed and a semiconductor laser is obtained.

Filed: 1989-09-14
Abstract: PURPOSE:To surely prevent drain flush and trouble such as water hammer in a feed water heater drain system by always replacing the drain of a drain bypass tube with the drain of the temperature corresponding to plant load. CONSTITUTION:A heat water replacement device 10 (including a throttle mechanism such as tubing, valve and an orifice) connecting near the inlet of a drain tank water level adjustment valve 9 of a drain pump bypass tube 6 is provided from halfway of a drain pump minimum flow tube 8 connecting a drain pump discharge tube 4 and a drain tank 2. Since a drain pump 3 is continuously operated during normal operation, a constant quantity is always allowed to flow in the drain pump minimum flow tube 8 for the prevention of the overheating of the drain pump 3. Accordingly, the drain pump minimum flow tube 8 is connected near the inlet of the drain tank water level adjustment valve 9 of the drain pump bypass tube 6, so that the drain in the drain pump bypass tube 6 always has the same temperature as the outlet drain of the drain pump 3 and the temperature does not exceed the saturation temperature of drain system pressure even if plant load is rapidly lowered.

Abstract: PURPOSE:To diffuse and weld metallic bumps completely by a method wherein the second active layer is arranged on the first active layer after adjustment and a bumping metallic block having parallel flat planes is laminated on them and a movable supporting member presses and heats them through a hard ball. CONSTITUTION:The first and second active layers 101 and 201 are brought in contact with each other after adjustment of the bumps are put on a fixed supporting member 301. A surface of the supporting member made of Fe and etc. is finished flatly and it is tightly in contact with a back side of the active layer 101. The overall surface of back side of the active layer 201 is covered with a bumping block 302 made of Fe and etc. whose sides are finished flatly and parallel, on which a hard ball 303 made of Fe is put and a contact point is determined in the vicinity of the center of the active layer 201. From the above of said hard ball 303, a pressure and a heat are applied (a pressing device 305) through a movable supporting member 304. By this constitution, the ball 303 and the plane 302 are in contact at one point so that a direction of pressure is corrected to be vertical to the layer 201 and the stress of the plane 302 and the ball 303 concentrated in the contact point is dispersed uniformly on the contact plane of the block 302. Accordingly, the metallic bumps of the surfaces of active layers are diffused and weld uniformly.

IPC: H01L23/28
Filed: 1992-09-07
Abstract: PURPOSE:To prevent generation of short circuit failure resultant from a mutual contact between the tips of adjacent outer leads and a solder bridge to a printed board during mounting in terms of a surface mount type IC package. CONSTITUTION:As an outer lead, two types of outer leads, say, gall-wing-shaped outer lead 2 and a J lead-shaped outer lead are alternately laid out on a surface mount type IC package. This construction is effective to prevent the contact between the tip of each adjacent outer lead when the outer leads are subject to deformation produced by external force. In addition to that, this construction makes it possible to set a semiconductor mounting section in two stages even when they are mounted to a printed board, take up a longer distance in the adjacent solder-mounting section and provide an effect to prevent the generation of a solder bridge.

Filed: 1989-09-13
Abstract: PURPOSE:To realize a circuit for input and a circuit for output with common hardware by providing a switching means which applies a signal to a common terminal and a switch control means which sends out the signal at the common terminal. CONSTITUTION:When an output instruction is received from a CPU 12, a signal level '1' is outputted from a control terminal 1 to a bus line 13 to turn on a photocoupler 8, a relay driving part 5 is driven to make a relay contact 6, and a driving part 14 is driven to perform output operation. When the contact 15 of an external relay is made to input a ground-level signal, the relay driving part 5 is driven to make a relay contact 7. Here, when the CPU 12 executes an input request instruction, the signal level of the bus line 13 is determined by the state of the relay contact 7 and the CPU 12 reads in the signal level from the control terminal 1 to detect the external contact 15 being made. Consequently, hardware for input and hardware for output are made common.

Abstract: PURPOSE:To reduce the effect on a filter characteristic due to an input capacitance of an active element or the like being a component of a buffer by connecting an output terminal of a 2nd buffer to a connecting point between a transconductance amplifier and a 1st buffer via a capacitor. CONSTITUTION:A buffer 3 is added between the 1st resistor R1 and the 2nd resistor R2 and one terminal of the 1st capacitor C1 is connected to a connecting point between the 1st resistor R1 and the buffer 3. Thus, the resistors and the capacitors are selected in a relation of R1=R2 and C1=C2 to obtain the setting of alpha=0.5, and since the circuit constant is entirely the same and it is not required to reduce the capacitance of the capacitor C2 to provide the same cut-off frequency, the error due to the capacitance of the active component is decreased.
