Title: Optical logic switch
Inventor: YAKIDA HIDEKI
IPC: H01S5/026
Filed: 1985-04-23
Abstract: PURPOSE:To enable the constitution of a general logic circuit and logic arithmetic operation as an optical signal is left as it is by simple constitution by a method wherein a plurality of lasers share the same active region, a negative gain region is inserted to one part of the active region, the gain of the negative gain region is changed and the state of oscillation is switched among a plurality of the lasers. CONSTITUTION:Active layers for two striped type laser diodes 1, 2 cross on the same plane, and mirror surfaces a, a' and b, b' each organize resonators for the lasers 1, 2. An optical absorption region (d) is inserted into the resonator shaped by the mirrors b, b'. When current density ia, ib, ic injected into the lasers 1, 2 and a crossed region (c) exceed a threshold, the laser 1 is oscillated, but the laser 2 contains the optical absorber (d), and is not oscillated owing to the negative gain region (c). When the optical absorber (d) is irradiated by beams and the laser 2 is oscillated, the region (c) is brought to the state of a negative gain, and the oscillation of the laser 1 is stopped.

Title: Semiconductor device with anode-side gettering
Inventor: HANSUUYOAHIMU SHIYURUTSUE
IPC: H01L29/861
Filed: 1995-03-20
Abstract: PURPOSE: To enable guttering on the anode side together with simple formation of a semiconductor substrate by an arrangement, wherein the anode band in the central range contains no phosphorus and at least a phosphorus doped band is embedded in the anode band in the fringe range. CONSTITUTION: An anode side emitter region 3 is additionally provided with a band, doped heavily with phosphorus formed in a fringe range 7 by diffusion implantation of phosphorus. On the contrary, the band 3 in the central range 6 contains no phosphorus. It is achieved by a simple method for shielding the central arrange 6 on the anode side surface 5 of a semiconductor substrate at the time of diffusion implantation of a cathode side emitter band 8. Phosphorus diffusion implanted into the band 10 serves to gutter impurities in the fringe range 7 of the semiconductor substrate from the anode side. Guttering does not take place from the cathode side of the fringe range 7. Consequently, guttering on the anode side can be effected, together with the simple formation of a semiconductor substrate.

Title: Rolling stock
Inventor: TOKUNAGA KEIZO
IPC: B61D49/00
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To reduce aerodynamic resistance and flow noise of rolling stock and make it high speed and low noise by mounting a member obtainable of optimum aerodynamic characteristic on at least either the lead car or the rear- end car in a freely detachable manner. SOLUTION: Regarding a rolling stock with a lead car and a rear-end car of identical configuration because they go and come back on a permanent way 1, a fairing member 5 is mounted on the rear-end car in a freely detachable manner. The fairing member 5 is made of a light weight material such as a reinforced plastic and mounted on a car with a plural number of bolts in a freely detachable manner. As a result, air flow in the surroundings of the rear end of the rear-end car 2 flows to the rear without exfoliating. Thus not only can aerodynamic resistance be reduced but flow noise can be reduced and speeding up and lowering noise of rolling stock can be accomplished. When the fairing member 5 is mounted on a lead car, restoration of any damage such as a bird crashing against the car while running can be facility accomplished by simply replacing the member.
