Filed: 1988-11-17
Abstract: PURPOSE:To obtain stable modulation gain and carrier level without applying adjustment by perform the direct switching of the output of a phase inversion circuit. CONSTITUTION:The phase inversion circuit 2 inputs a voice signal V to the base of a transistor Q1, and outputs an output signal O1 in a form in which positive potential from emitter side output is added on a signal with a phase negative to that of the voice signal V from the collector side of the transistor Q1, and inputs it to an analog switch 3. Similarly, the circuit outputs an output signal O2 in a form in which negative potential from interface side output is added on the signal in-phase with the voice signal V from the emitter side of the transistor Q1, and inputs it to an analog switch 4, The analog switches 3 and 4 repeat conduction and nonconduction alternately by a clock signal CL and an inversion clock signal, the inverse of CL from a clock signal generation circuit 6, and as a result, a voice signal VM to be modulated whose amplitude is modulated by a clock frequency appears at a modulation signal output terminal 5. In such a way, it is possible to obtain the stable modulation gain and the carrier level without applying the adjustment.

Title: Double leaf valve
Inventor: KIDO HITOSHI
IPC: F16K1/22
Filed: 1989-11-10
Abstract: PURPOSE:To prevent breakage of a packing by coupling one end of an arm, whose other end is fixed to the rotational center at the side face of a valve element with a servo motor using an eccentric pin, allowing the valve element to tilt a little to the open side while taking the full close attitude, and by precluding excessive full closing to be caused by water stream. CONSTITUTION:One end of an arm 21 is fixed to the rotational center 15 of a valve element 3, while the other end is coupled with a servo motor rod by an eccentric pin 25. This eccentric pin 25 is made in such an arrangement that the arm side center L1 of a cylindrical arm holding part 25a is eccentrical by an amount e2 to the rod side center L2 of a cylindrical rod holding part 25b. Even though the motor rod is moved to the full close position, therefore, the actual center line of the arm 21 will be 21a, and also the center line of the valve element 3 be situated at the center line 3a which is open by an angle thetafrom the center line 3a' of full closing. Accordingly, when Fe pipe water 6 with high pressure is applied to the valve element 3, it will take the normal close position (center line X), which prevents the breakage or wear of packing due to excessive valve closing.

Title: Electronic photograph type printer
Inventor: SAKAKI KAZUO
IPC: B41J29/48
Filed: 1989-11-10
Abstract: PURPOSE:To detect the paper winding without an error and omission by a method wherein the light incident angle of an luminant element is made larger than that of the normal on the surface of a sensitizing drum. CONSTITUTION:When the attaching angle of a luminant element 1 is changed so that the incident angle is diagonal to the drum surface, that is, at an angle smaller than 90 deg. to the drum surface, the reflection light strength VD from the luminant element 4 on a sensitizing drum 1 is significantly reduced. On the contrary, the level of the reflection light strength Vp from a sheet of paper 2 wound around the sensitizing drum 1 does not change so much because of irregular reflection due to the fine uneven surface of the paper 2. Therefore, the distance between VD and Vp becomes wider compared to former ones, so that the reference voltage Vr can be set in the middle between VD and Vp with an allowance and an error in detecting paper winding can be satisfactorily prevented.
