Title: Pbte lattice matching material and its manufacture
Inventor: SAKURAI NOBUHIRO
IPC: H01S5/00
Filed: 1994-02-02
Abstract: PURPOSE:To obtain a semiconductor laser device using a PbTe layer as an active layer by using a quaternary mixed-crystal thin film containing Pb, Sr, and Te as the lattice matching layer of the PbTe layer. CONSTITUTION:After forming a PbSrTe film on a substrate 8, the substrate 8 is held on a hot wall tube 6 for 2 to 3 seconds. Since the source section of the tube 6 heats Mg, Sr and Mg are mixed in and bonded to the PbTe of the thin film and form a PbMgSrTe thin film. As a result, a film which has a large band gap and the lattice of which matches that of the PbTe can be obtained. Therefore, a semiconductor laser device using the PbTe layer as an active layer can be manufactured.

Title: Vertical synchronous separator circuit
Inventor: OKAJIMA MASAYUKI
IPC: H04N5/10
Filed: 1986-02-28
Abstract: PURPOSE:To prevent the erroneous detection of a vertical synchronizing signal with a simple constitution by giving a register reading in a composite synchronizing signal at a clock which has a frequency twice a horizontal synchronizing signal and rises at the prescribed timing, a pulse generator circuit which uses the fall of an output signal from said register as a trigger and outputs a pulse with the prescribed width, an OR gate circuit and the 2nd register. CONSTITUTION:The clock S2 has the frequency twice a horizontal synchronizing signal and the rise of its pulse lying between the two equalization pulses adjacent to the composite synchronizing signal S1. If the composite synchronizing signal S1 has a noise pulse N in the horizontal synchronizing signal H, the output signal S3 of the register 1 becomes a waveform as illustration shows. When said signal is inputted to a monostable multivibrator 2, a pulse S4 with a pulse width W shown by the illustration is outputted, and therefore the output signal S5 of the OR gate circuit 3 becomes a high level without fail. Accordingly an output signal S6 also comes to a high level, and the noise pulse N is not erroneously detected as a vertical synchronization. Here, the width W is longer than the frequency T of the clock and shorter than a vertical synchronizing period.

Abstract: PROBLEM TO BE SOLVED: To effectively and accurately detect foreign objects caught by a power window according to fluctuation in a load on a motor by providing a driving sensor, which outputs speed signals corresponding to the driving speed of a vehicle and a means for varying overload value, based on the signals from the driving sensor. SOLUTION: According to the length of the cycle of traveling pulses from a driving sensor 13, the resistance value of a reference resistance circuit portion 7 connected with the reference resistance connecting terminal T4 of IC 5 for load power supply control is varied through a trigger circuit portion 9 by switching between a combined resistance of reference resistors Rr and Rr3 and a combined resistance of reference resistors Rr1 and Rr3 which is higher than the former combined resistance. The overcurrent determining value associated with a motor 3 set by the resistance value of the reference resistance circuit portion 7 is varied.  For this reason, even if frictional force acting on the window when the window is opened and closed is increased so that the load on the motor 3 is increased, the determined value of the overcurrent associated with the motor 3 is revised upward and power supply from a battery 1 to the motor 3 is prevented from stopping.

IPC: H01P5/02
Filed: 1986-02-26
Abstract: PURPOSE:To improve the high speed characteristic by providing additionally an impedance matching member decreasing the capacitance to the rear face of a circuit board corresponding to a terminal requiring impedance matching. CONSTITUTION:A microstrip line 3 and an earth pattern 7 are formed on the circuit board 1 and a terminal 21 of a high speed IC 2 is connected to the line 3. Although the impedance matching is applied by using a stub (not shown in a figure) provided additionally to the line 3 at the terminal 21 requiring the impedance matching, impedance mismatching is still caused at the terminal. Thus, the structure is adopted that the capacitance increase due to the terminal 21 is decreased by providing an impedance matching member 6 made of a metal forming a recess 61 to a part removed of the earth face of the earth pattern 7 at the rear face of the board 1 to the earth pattern. Thus, the capacitance is adjusted by adjusting the width, depth of the recess 61 formed to the member 6.

Abstract: PURPOSE:To improve the yield of an element by providing material gas having molecules which at least do not contain a carbon atom. CONSTITUTION:A reaction room 1 and a plasma generating room 4 are evacuated to approximately 10<-5>Torr using a vacuum system, the gasified liquid nitrogen is sent to a cooling mechanism 2 and a substrate 3 is cooled to -150 deg.C. Monosilane 11 is sent as material gas, and when the pressure in the room 1 becomes higher than the saturation vapor pressure of the gas 11 at -150 deg.C, the monosilane dews on the surface of the cooled substrate 3 and a fluid film is formed. The liquified monosilane 11 flattens level difference caused by an aluminum wiring on the substrate 3 by surface tension. Oxygen is sent to the room 1 so as not to permit the pressure in the room to be lower than the vapor pressure of the monosilane 11. A microwave of 2.45GHz is made incident on the substrate 3 and the substrate is plasma processed. An electronic cyclotron resonance plane is positioned at a distance of 2cm from the substrate by a magnetic coil. Thus, process is simplified and the yield of the element is improved.
