Title: Phase detector
Inventor: OGAWA NOBUYUKI
IPC: H04N9/87
Filed: 1990-05-18
Abstract: PURPOSE:To facilitate circuit integration by latching or integrating a burst data with three clocks whose phases differs by 90 deg. each and detecting th burst phase depending on the combination of the result of comparison of latch of 1st, 2nd and 3rd clocks or the result of integration. CONSTITUTION:For example three S/C signals whose phases differs by 90 deg. each are used to latch a burst data. For example, the burst is latched at a latch 39 by using the reference S/C signal, the burst is latched at a latch 40 by using the S/C signal led by 90 deg. with respect to the reference S/C signal and the burst is latched at a latch 41 by using the S/C signal led by 180 deg. with respect to the reference S/C signal. Then the difference of the data latched by each clock is taken to check a direction of a change between the data, then the burst phase is dicriminated independently of the absolute value of the data. Thus, the burst phase is detected entirely independently of burst level fluctuation or pedestal level fluctuation.

Thus the rotary power is selectively transmitted in response to the turning direction of the gear 37. When the end of the forward travelling of a tape is detected, an automatic inversion operating lever 97 is operated in the same operating direction as the reproduction levers 87 and 90. Then the trigger part 97a of the lever 97 touches a trigger holder pin 83b of a transmission gear 83 to give the counterclockwise rotary trigger to the gear 83. Thus an instantaneous engagement is secured between the gears 83 and 37 to obtain the backward reproduction mode of a tape.

Title: Integrated circuit
Inventor: KOYAMA KAZUMI
IPC: H03K5/13
Filed: 1982-07-23
Abstract: PURPOSE:To increase the delay time even with the same capacitance of a capacitor, by supplying a low voltage value as a power supply voltage of each inverter constituting a delay circuit to extend the charging time of the capacitor. CONSTITUTION:A power supply of the inverter constituting the delay circuit is provided with a special power supply circuit 5 in a semiconductor integrated circuit including the delay circuit 2. A negative polarity output signal 20 of an input circuit 1 charges up the capacitor 25 into a positive voltage via an inverter 21. When the capacitor 25 is charged to a prescribed level, an output level of the inverter 22 is inverted and a capacitor 26 is charged. Since the delay time of one stage is determined with the charging time of the capacitor, the capacitor is charged with an output of the inverter taking a low voltage of the power supply circuit 5 as the power supply. Thus, the delay time is increased even without large capacitance of the capacitor and the occupied area in the integrated circuit is not increased.

Title: Oxide sticking amount detector for electrode
Inventor: OONUMA KATSUYOSHI
IPC: G01N27/00
Filed: 1978-10-24
Abstract: PURPOSE: To secure a high-accuracy detection for the oxide sticking amount to the electrode by measuring the voltage caused to the electrode before and after the oxide sticking to the electrode by means of a pair of wind tunnels composed of the high and low temperature atmosphere rooms and then obtaining the integral value of the voltage variation caused by the temperature change.  
     CONSTITUTION: A pair of wind tunnels composed of high temperature and low temperature atmosphere rooms 6 and 7 is provided before and after oxide sticking device 4. Electrode 1 attached to lead wire 3 of stem 2 is installed in room 6 of the left wind tunnel and then held until a fixed temperature is secured. After this, the prescribed faint current is applied to electrode 1, and the voltage produced at electrode 1 is measured. At the same time, electrode 1 is shifted to room 7, and the voltage variation caused in this period is integrated to obtain integral value V 1 . Then the oxide is stuck to electrode 1 via device 4, and electrode 1 is shifted to the right wind tunnel to carry out the same operation as the above. Thus integral value V 2  is obtained for the voltage variation caused by shifting of the electrode between the high and low atmosphere rooms. After this, the value (= VW) of V 2 -V 1  is calculated and then converted into the weight unit, thus obtaining the oxide sticking amount.

Title: Current switch
Inventor: NODA TSUTOMU
IPC: H03K17/687
Filed: 1983-07-19
Abstract: PURPOSE:To attain quick switching operation by providing a bipolar transistor (TR) between an MOS TR conducting current switching from a current source and a load so as to avoid a control voltage from being restricted by a potential of the load. CONSTITUTION:When the control voltage is applied to an input terminal 8, the MOS TR11 is turned on because the resistance between its drain and source is lowered and a current flows from the load 5 via the bipolar TR14 and the MOS TR11. The operating potential of the current source is unchanged even if any of the MOS TRs 11, 12 and 13 is turned on to loads 5, 6 and 7 having a different potential because the base potential of bipolar TRs 14, 15 and 16 is fixed by the potential of the voltage source 17. Further, the switching operation is attained quickly.
