Patent JP-S58207690-A (JP)
Title: Buried type semiconductor laser
Inventor: MITO IKUO
IPC: H01S5/00
Filed: 1982-05-28
Abstract: PURPOSE:To reduce a reactive current flowing into the circuit other than optical waveguide of the InGaAsP active layer and improve temperature characteristic by employing a P type InP substrate, N type InP current confinement layer, P type InP current blocking layer. CONSTITUTION:Since P type InP substrate 1 is used, an NPN transistor part sandwiches the InGaAsP active layer 5 having small band gap energy, efficiency of implanting electrons which are minor carriers to the P type InP clad layer 4 from the N type InP clad layer 6 is low and a current gain of NPN transistor is low. As a result, a switching voltage of pnpn layer becomes high and a current almost does not flow for a voltage applied during normal operation. As described above, a reactive current flows a little to the area other than the optical waveguide 5C of InGaAsP active layer. Therefore, good linearity of injected current-optical output can be obtained and a high output can also be obtained. Moreover, even when an oscillation threshold current density increases under a high temperature, increment of reactive current is small and good temperature characteristic can be obtained.

Title: Adhesive sheet
Inventor: NISHIOKA YUJI
IPC: H02K3/34
Filed: 1991-04-22
Abstract: PURPOSE:To offer an adhesive sheet excellent in shaping and molten resin holding properties. CONSTITUTION:When an sheet 3 relating to the present invention is deformed into a prescribed shape while being closely attached to a substance to which it is to be stuck followed by processes of a resin part 33, for instance, by heating and then solidifying it, the adhesive sheet 3 is stuck to a substance to which it is to be stuck by the resin part 33. Since especially, in this invention, a large number of small holes 31 are opened on a sheet part 32, the adhesive sheet 3 can well maintain its bendability (flexibility) inspite of its increased thickness so as to be easily bent into a desired shape. Further, since small halls 31 have a function to store a molten resin part 33, molten resin is hindered to flow out to the outside.

Abstract: PURPOSE:To reduce the capacity of a battery for power failure and to increase the reserving frequencies for break of a power supply, by storing a power supply break reserving table in an external storage and then delivering a difference to the present time point to supply it to a counter backed up by a spare power supply. CONSTITUTION:A power supply break reserving table is stored in an external storage 13. A CPU1 compares 15 the present time point of a timepiece device 14 with the data of the storage 13 and then stores the difference of comparison to a counter 22 via an interface control circuit 21 of the main body 21 of an automatic power supply breaking device. The value of the counter 22 is subtracted by a clock 23 with each fixed time, and an attached equipment driving circuit 25 is controlled via a comparator 24 when the balance of the counter 22 is set at 0. Then the power supply is broken for a distribution board 7, an air-conditioning equipment 8 and an illuminating equipment 8 respectively. The counter 22 contains a back-up battery and therefore can keep its operation despite a power failure occurred during its operation. This enables an automatic break of a power supply for a long period of time and can also reduce the capacity of a spare battery. This device is suited to an unmanned and labor saving program of an information processor.
