Title: Transmitter
Inventor: SUGANO MASASHI
IPC: H04B1/04
Filed: 1986-07-22
Abstract: PURPOSE:To simplify a transmitter and to hold a transmission output stable against temperature variation and level variation of an input signal by using a single diodes for the detection of transmission electric power and the detection of ambient temperature in common, and making transmission lines to a level controller into one system. CONSTITUTION:Variation in the terminal voltage across the diode 13 with temperature is detected to use the diode even for the temperature detection. When no transmission is performed, namely, when no input signal is applied to an input terminal 22, a controller 20 controls a switch 17 to control a transmission line 14 to a voltage holder 21 (i.e. a 1st level controller 15) (contact A). When transmission is performed, the switch 17 is connected to the side of a contact B by the controller 20. At this time, the voltage holder 21 holds the value right before the switch 17 leaves the contact A. In this state, the diode 13 detects the transmission output, so a 2nd level controller 16 operates according to its rectified DC voltage and the constant transmission output is obtained even when the input signal varies in level.

Title: Printing hammer
Inventor: MORIKAWA SAICHI
IPC: B41J9/38
Filed: 1989-07-03
Abstract: PURPOSE:To increase air resistance at the return time of a plunger, to reduce the collision pressure to a stopper at the time of rebounding and to suppress the generation of sound by adding a valve mechanism to the plunger. CONSTITUTION:The plunger 1 stopped at the position of a stopper 3 by a spring 2 flies out toward a platen 5 by exciting a coil 4 for a definite time. At this time, a valve 7 is opened and the plunger 1 moves while receives small air resistance. The plunger 1 impinges against the platen 5 to perform printing and subsequently returns toward a stopper 3 by the repulsive forces of both of the platen 5 and the spring 2 but, at this time, the valve 7 is closed. Therefore, the plunger 1 is decelerated by large air resistance and reaches the stopper 3 by slight pressure. Since pressure is low when the plunger 1 reaches the stopper 3, almost no rebounding is generated and generated sound is also little.

Title: Tape position control system
Inventor: TSUCHINAGA HIROYUKI
IPC: G11B7/0055
Filed: 1988-07-13
Abstract: PURPOSE:To reduce burden applied to a tracking servo mechanism so that the tracking can be more stabilized by controlling the position of a magneto-optical tape by optically checking the movement of the tape in a lateral direction while the tape is run. CONSTITUTION:Optical tapes 1a and 1b are wound around a cylinder composed of an upper and lower stators 3a and 3b by means of guide rollers 2a and 2b and guided by a guide belt so that the tapes 1a and 1b can be run through normal positions. Bisected photodetectors 5a and 5b are provided on the stator 3b above the belt 4 and irradiated by light from light sources 6a and 6b. Light-transmissive section 7a and 7b are provided on the optical tapes 1 at the same interval as that between the detectors 5a and 5b. Therefore, when it is discriminated that the tapes 1 are dislocated from the normal positions from the light-transmissive sections 7a and 7b when the sections pass over the detectors 5a and 5b, the detectors 5a and 5b output a differential signal which is proportional to the dislocated quantity of the tapes 1. When the differential signal is outputted, the tapes 1 are returned to the normal positions by expanding or contracting piezo-electric elements 10a and 10b. Therefore, the burden applied to a tracking servo mechanism can be reduced and the tracking is more stabilized.

Title: Word line discharging circuit
Inventor: OKAJIMA YOSHINORI
IPC: G11C11/414
Filed: 1983-09-19
Abstract: PURPOSE:To heighten the power supply margin of the discharge current origin and to obtain nonreverse current circuits of holding currents by connecting the respective negative word lines through the section between the collector and emitter of the transistor to the discharge current origin and connecting the base of the said transistor through the resistance to positive word lines which are paired with the negative word lines. CONSTITUTION:When WL1 is assumed to be a selective word line, the W<+> line electric potential is decreased at the time of transfer to nonselection, and accordingly, the base current IB and collector current IC of an npn type Tr T1 are also reduced, and therefore, the current is led-in in correspondence to word line electric potential and the word line electric potential is decreased. When WL1 is assumed to be a nonselective word line, the Tr T1 is saturated and prevents reverse current. Since the voltage drop of resistance R1 can be disregarded, the electric potential difference between W<+> and current origin IDIS becomes a voltage VBE between the base and emitter of the Tr T1, and a W<-> electric potential becomes W<+>-VBE. Consequently, the W<-> electric potential is equal to the current origin IDIS. Under this condition, the Tr T1 operates at the saturated region, a current value IB for the current IC becomes larger and reverse currents from other nonselective word lines are suppressed. Moreover, since the Tr T1 emitter electric potential is W<->, the power supply margin is not decreased.
