Patent JP-H0438890-A (JP)
Title: Semiconductor laser device and manufacture thereof
Inventor: YOSHIDA KAZUTOMI
IPC: H01S5/00
Filed: 1990-06-04
Abstract: PURPOSE:To prevent a leak current from flowing by forming spacer layers for current checking on both sides of a double heterostructure region. CONSTITUTION:A p-InP spacer layer for checking currents approximately 1mum thick is interposed between a double heterostructure region and a current checking region 14, and this p-InP spacer layer 5 performs the same action as the p-InP current checking layer 7a in a semiconductor laser device, and an n-InP current checking layer 6 and a p-InP current checking layer 7 perform the same actions as the n-InP current checking layer 6 and the p-InP current checking layer 7b in the semiconductor laser device, respectively. Hereby, the leak path from the current checking layer to a clad layer 4 or 8 is never formed, and it has the effect that the leak current becomes extremely small. Moreover, it does not need the solid phase diffusion, wherein accurate control is mandatory, for converting one part of the n-InP current checking layer into p-InP, so a semiconductor laser device, which operates at a low threshold and excellent in temperature properties, can be obtained with simple process and at high yield rate.

Title: Transformer protecting relay apparatus
Inventor: USUI MASAJI
IPC: H02H7/045
Filed: 1989-06-09
Abstract: PURPOSE:To realize a two-phase AND function and a duplicated relay function by using the two-phase AND signal of a duplicated three-phase transformer protecting relay and connecting relay contacts, which are driven by two-phase AND signal and a three-phase OR signal, to each other in series. CONSTITUTION:A two-phase AND function is realized by AND circuits 44-46 relating to contacts 61 in the series route of contacts 59 and the contacts 61. Further, the function is realized also by AND circuits 41-43 relating to contacts 60 in the series route of the contacts 60 and contacts 62. A duplicated relay function is constituted by the combinations of the contacts 59 and 61 and the contacts 60 and 62. A malfunction due to a defective unit does not results in an apparatus malfunction. It is assumed that, for example, a relay 8 becomes inoperative. Taking it into consideration that a two-phase relay is operated by an inside fault, in a case wherein, for example, the relay 8 and a relay 10 are to be operated, positive operation is performed by the closure of the contacts 59 due to the formation of an OR circuit 49 and by the closure of the contacts 61 due to the formation of the AND circuit 46 by the operation of relays 21 and 23.

Abstract: PURPOSE:To obtain a base provided with a resistor being excellent in a sliding property and humidity resistance and having a low resistance value by a small number of processes by a method wherein the resistor provided on the surface of the base is constructed of two, upper and lower layers having different resistance values and the resistance value of the upper layer side is made higher than that of the lower layer side. CONSTITUTION:Lead terminals 3 to 5 are buried in a resistant base 1, while a resistant 6 is molded in the surface of the base so that is exposed on the same plane with said surface. The resistor 6 is composed of two, upper and lower layers being different in a resistance value, and the resistance value of a resistance layer 6a on th upper side is made higher than that of a resistance layer 6b on the lower side. Accordingly, the upper-side resistance layer 6a coming into slidable contact with a slider 25 contains more binder resin than the lower-side resistance layer 6b and the binder resin fills up pores among carbon powder particles sufficiently. According to this constitution, the resistor base being excellent in humidity resistance and resistance is obtained and, besides, the resistance value of the resistant is equal substantially to a low resistance value that the lower-side resistance layer has, due to a structure wherein the upper-side resistance layer and the lower-side resistance layer are connected in parallel electrically. Thus, the resistor base of the low resistance value is obtained.
