Title: Semiconductor light-sensing element
Inventor: OGITA SHOICHI
IPC: G01J9/02
Filed: 1988-08-24
Abstract: PURPOSE:To make it possible to convert a wavelength variation of an incident light into an electric signal by controlling a refractive index of a semiconductor light-sensing element, by adjusting thereby a distance between two reflection films to change an output current characteristic and by setting said wavelength variation in a part of the output cuerrnt characteristic approximating to a straight line. CONSTITUTION:A semiconductor light-sensing element is prepared by forming an n-type InP 36, an InGaAsP absorption layer 35, a p-type InP clad layer 34 and an n-type InP clad layer on an n-type InP substrate 37, by forming an SiO2 protection film and by forming thereafter a p-side electrode 31 and an n-side electrode 38. Then, a reflection film 39 of silicon having a reflectivity of 90% or above is formed on an end face by evaporation. In order to detect an incident light, the temperature and the electric field of the semiconductor light-sensing element are controlled to control the refractive index of the absorption layer 35, and the central frequency of a wavelength variation of a modulated incident light is aligned with the part of an output current characteristic approximating most to a straight line. Next, a negative reverse bias is applied on the electrode 31 by a DC power source 42, while a positive one is applied on the electrode 38 thereby, and an output current 40 which varies following a subtle variation of a wavelength is detected by a detecting means 41.

Title: Power transmitting device
Inventor: SHIMAMOTO MASAO
IPC: F16D43/284
Filed: 1986-09-06
Abstract: PURPOSE:To enable the distribution of torque between an input shaft and an output shaft to be optionally controlled, by providing a power interrupting clutch, oil pump and an oil pump operating clutch in a power transmitting device suitable for a transfer device in a four wheel driven vehicle. CONSTITUTION:In case of turning off solenoid valve 45 and draining pressure oil in an oil chamber 41 in the engaging direction side of an oil pump operating clutch 40, if an oil pump 31 is driven by an input shaft 11, a movable side oil pump body 30 also rotates in a follow-up motion to the input shaft 11 by driving resistance of the oil pump 31. Consequently, a delivery pressure of the pump 31 is almost zero, and almost no torque is transmitted from the input shaft 11 to an output shaft 13 by almost zeroing also an oil pressure of an oil chamber 51 in the engaging direction side of a power interrupting clutch 50. Accordingly, a perfect condition of two-wheel driving can be obtained in the time of high speed running. While the solenoid valve 45, it it is turned on, increases an oil pressure in the oil chamber 41, and a piston 42 is forced to be firmly attached to the pump body 30, fixing the pump body 30. The clutch 50 is engaged by introducing the delivery pressure of the pump 31 to the oil chamber 51.

IPC: H04L12/70
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To improve a conventional call control system for ISDN packet exchange which requires a change in the definition of a call originating side terminal synchronously without fail even when the definition of the subaddress of a call terminating side terminal is changed and that change is temporal. SOLUTION: A call identification code is added other than the subaddresses of plural call terminating side terminals 2 and 3, a translation table making the call identification code and the subaddresses correspondent to a call originating side terminal 1 and the call terminating side terminals 2 and 3 is stored inside and when calls are terminated, the call terminating side terminals 2 and 3 watch the call identification code to judge whether the call originating side terminal 1 is the desired party to connect or not. When it is not the desired party to connect, the sub-address of the desired party to connect is reported to the call originating side terminal.

Title: Master cylinder made of synthetic resin
Inventor: NAKAMURA KAORU
IPC: B60T11/16
Filed: 1982-11-30
Abstract: PURPOSE:To restrain the deflection of a mounting flange piece in braking by integrally providing a cylinder portion having the diameter larger than the outer diameter of the outer periphery of a cylinder and coaxially extending from the front end to the rear end of a slide portion of a piston and the mounting flange piece. CONSTITUTION:A cylinder 11, a reservoir 12, a cylindrical portion 13 and a mounting flange portion 14 are integrally formed of FRP of staple fiber mixed with proper synthetic resin. The cylindrical portion 13 is connected to the cylinder 11 and a portion of the reservoir 12 at the approximately central outer peripheral portion of the cylinder and extends by a predetermined length toward the rear end side coaxially with the cylinder 11, having the diameter larger than the outer diameter of the cylinder 11. Also, each mounting flange piece 14 projects radially outward by a predetermined length from the rear end outer peripheral portion of the cylindrical portion 13. Then, the length l1, l2 from the outer peripheral portion to a mounting hole 14a of the mounting flange 14 are shorter than conventional length L1, L2. Thus, even if a load is applied on the cylinder 11 in braking, each mounting flange piece 14 is restrained from the deflection.

Filed: 1981-12-28
Abstract: PURPOSE:To enable the coincidence of a sweep reception characteristic and the frequency sweep characteristic of a frequency marker signal, by mixing the output of a sweep local oscillation unit with the output of a variable frequency oscillation unit to obtain the marker signal. CONSTITUTION:A reception input signal is mixed in a mixing unit 1 with the output of a sweep local oscillation unit 5 controlled by the output of a sweep signal generating unit 6. Then it is amplified and detected as an intermediate frequency signal by a detecting unit 2 and given to a video mixing unit 3.

Accordingly, when the frequency of the reception input signal coincides with the frequency from the variable frequency oscillation unit 9, a composite video output of the video mixing unit 3 appears with superposed frequencies. The variable frequency oscillation unit 9 is controlled by a manual frequency control unit 10, and a marker frequency is displayed in a frequency display unit 11.

Title: Driving circuit for laser diode
Inventor: KOSEKI TOSHIICHI
IPC: H01S5/042
Filed: 1984-10-08
Abstract: PURPOSE:To omit wasteful currents, to reduce supply capacitance and to improve electric/optical conversion efficiency by fitting a switch switching by clock pulses or signal pulses connected to a laser diode or the series connecting circuit of the laser diod and a CR parallel connecting circuit. CONSTITUTION:When signal pulses S transmitted from a modulator MOD rise, an N-P-N transistor TrQ1 is conducted, driving currents rise, and currents flowing through a laser diode LD rise. An P-N-P TrQ2 is interrupted by the rise of clock pulses CLK at the same time, a parallel circuit to the LD is opened, the inter-terminal voltage of the LD suddenly rises, and charging currents flow into the junction capacitance of the LD. The storage charges of the Q2 are discharged through the LD. Consequently, an optical output P from the LD suddenly rises. When signals from the MOD fall, the Q1 is interrupted, the Q2 is conducted, a parallel circuit is formed, and the optical output from the LD rapidly falls. The parallel circuit is opened during the driving of the LD, thus omitting wasteful currents.
