Title: Semiconductor light amplifier
Inventor: TAKEDA YASUTOSHI
IPC: G02B6/34
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To facilitate optical axis adjustment for introducing light to a gain region and obtain a stable amplifier of high gain by providing a converging means for introducing light from the outside to a gain region. SOLUTION: A semiconductor light amplifier comprises a gain region 1, a semiconductor layer 2, a coating 3 deposited on an amplifier edge face for transmitting light close to a hundred percent and a converging means 7 for introducing light 5 from the outside to a gain region 1. The converging means 7 consists of a transparent medium whose reflectance is high than that of the gain region 1 and is formed in a wedge shape, and an edge part thereof is formed to coincide with an amplifier end part position and a bottom surface is arranged to be brought into contact with an upper part of the gain region 1 as a boundary surface with the gain region 1. Light 5 from an outside which is entered into the slope is entered to a boundary surface with the gain region 1 at a critical angle or less.  Thereby, light proceeds along the boundary surface without receiving total reflection, and is injected to the gain region 1, amplified and projected from an amplifier to an outside as output light 6.

Patent JP-S6464259-A (JP)
Title: Lateral transistor
Inventor: ATSUMI TSUGUKAZU
IPC: H01L29/732
Filed: 1987-09-03
Abstract: PURPOSE:To efficiently decrease current amplification factor of a parasitic transistor, by providing an auxiliary base region and a capture region so that a part of collector current of the parasitic transistor is returned to the base side for increasing base current. CONSTITUTION:In an island region 18, a highly doped auxiliary base region 40 having the same conductivity type to that of the island region 18 is formed in a cup-like shape. Among minority carriers injected into a base region 14 from an emitter region, carriers moving toward a collector (a substrate 10 and an isolating region 16) of a parasitic transistor Q2 are thereby obliged to pass through the auxiliary base regions 12 and 40 having high dopant concentration and therefore practical emitter injection efficiency is decreased. Further, a capture region 42 having the opposite conductivity type to that of the island region 18 is formed outside the collector region 22 of an intrinsic lateral transistor Q1. Any minority carriers not absorbed by and leaked from the collector region 22 will be captured efficiently by the capture region 42. Accordingly, a part of collector, current is returned as base current and, as a result, base current can be increased.

Title: Register reference holding mechanism
Inventor: KAWAMOTO YASUHIKO
IPC: G06F11/28
Filed: 1987-09-01
Abstract: PURPOSE:To know the reference state to all registers by using the strobe signal to set the corresponding bit or a register reference holding register. CONSTITUTION:When an instruction is evaluated, the contents of a holding register 105 are cleared by an instruction which activates a reset signal 107. Then a selection signal 102 serves as the number of a reference register in case a read or write request is given to a register in a register group 101 due to occurrence of an event like execution of an instruction, etc. A decoder 103 decodes the signal 102 and activates the strobe signal 104 to be applied to the reference register in the group 101. At the same time, a set signal 106 of the corresponding bit of the register 105 is also activated to set its corresponding bit. Thus it is possible to read out the register 105 by an exclusive instruction and to check the reference state of the register after occurrence of an event.
