Title: Driving system of tape recorder
Inventor: SHIMIZU RIYOUTA
IPC: G11B15/50
Filed: 1981-11-11
Abstract: PURPOSE:To save energy while preventing an unnecessary friction slip, by transmitting the rotation of a motor to a differentail gear device to generate two differential outputs, and driving a capstan by one differential output while driving a reel turntable by the other output. CONSTITUTION:The rotation of a motor 22 is transmitted to a planet gear through a pulley and a belt 32, and its internal gear rotates to generate a differential output between an external gear 30 and an intermediate gear 34. The rotation of the intermediate gear 34 is transmitted to a reel turntable 42. The rotation of the external gear 30, on the other hand, is transmitted to a capstan 14 and a tape 48 is fed as shown by an arrow 54 by the capstan 14 and a pinch roller 46 and wound around a tape roll 48a. In this constitution, the turning driving force of the motor 22 is transmitted firstly to the less-loaded reel turntable 42 through the intermediate gear 34 to eliminate the sag of the tape 48 between the tape roll 48a and capstan 14, and consequently the tape 48 while always tensed is fed by the capstan 14 driven through the external gear 30.

Title: Recovered toner detecting device
Inventor: NAKADE TOSHIYUKI
IPC: G03G21/00
Filed: 1989-07-13
Abstract: PURPOSE:To reduce erroneous detections as to whether a toner is present or absent in a recovered toner container, which is caused by the soil of the inwall of the recovered toner container by providing a means running a second pulsative light emitting current having a peak value higher than that of a first light emitting current to a light emitting element. CONSTITUTION:If it is detected that a toner recovering tank 5 is in a prescribed position, a LOW level signal is outputted to a output port P1, a transistor Q1 is turned off, and a HIGH level pulse is outputted from an output port 2. Consequently, when a pulsative voltage is supplied from the port 2 and a transistor Q2 is repeatedly turned on and off according to the voltage, a light emitting diode 7 runs a pulse current having a sufficiently high peak value, so that, its light emitting quantity is high and the light of the light emitting element 7 can transmit a toner quantity detecting part 6, even if the inwall of the toner quantity detecting part 6 is soiled with toner adhesion. Thus, erroneous detections as to whether toner is present or absent in a toner recovering tank, which is caused by the soil of the toner quantity detecting part, is reduced.

Title: Two-line/four-line converting circuit
Inventor: TAKATO KENJI
IPC: H04B3/03
Filed: 1985-08-20
Abstract: PURPOSE:To make a two-line/four-line converting function into an LSI together with a power supply part by converting a current converting a four-line input signal into a voltage current by a mirror circuit into a two-line signal without a frequency characteristic and making a differential amplifier convert said signal from balance to imbalance. CONSTITUTION:The four-line input signal is converted into a current in proportion to a two-line load impedance 1 and a terminal impedance 2 by a voltage/ current converting circuit 6, and the converted current is inputted to mirror circuits A0 and B0 comprising the power supply part through mirror circuits A3 and B3 and outputted as the two-line signal without a frequency characteristic from the mirror circuits A0 and B0. Then the differential amplifier OP3 applies the balance-imbalance conversion to the two-line input signal. If the converted signal includes the four-line input signal, it is outputted from the amplifier OP3 in the reverse phase of the four-line input signal applied to a four-line input terminal 4WR. Consequently, resistances RS and RR cancel the turned four-line input signal, and an arithmetic amplifier OP4 corrects frequency and outputs the four-line signal.

Title: Piezo-electric ultrasonic transducer with conductive bonding agent
Inventor: YAMAMIZU HIDEICHIRO
IPC: G01N29/04
Filed: 1985-08-20
Abstract: PURPOSE:To efficiently produce and transmit ultrasonic wave by bonding a piezo-electric vibrator on the end face of a sound field medium using a conductive bonding agent and using the bonding layer in common as an internal electrode of the vibrator. CONSTITUTION:An ultrasonic vibrator 2 is bonded on the end face of a sound field medium 4 (object), and generated ultrasonic wave is transmitted efficiently in the sound field medium. Electrically insulating material such as silicone resin, cyanoacrylic resin, epoxy resin, etc., is used for such acoustic bonding agent. An electrode 1 is attached on the end face of the sound field medium, and a piezo-electric vibrator is bonded on it, and voltage is applied between the surface electrode of the vibrator and end face electrode of the sound field medium through the bonding layer. In this method, the specific permittivity of the bonding layer is extremely small than the specific permittivity of the piezo-electric vibrator, accordingly, the small electrostatic capacity enters the piezo-electric vibrator in series even when the bonding layer is made as thin as possible, and it is not possible to apply sufficient voltage to the vibrator, and excitation becomes inefficient. Thus, efficiency of generation of ultrasonic wave and efficiency of transmission of generated ultrasonic wave to the sound field medium can be improved.

Title: Method for stabilizing surface potential of electrophotographic photosensitive body
Inventor: NOGUCHI TERUHIKO
IPC: G03G15/00
Filed: 1987-07-21
Abstract: PURPOSE:To stabilize electrification potential, by changing a static eliminating light quantity fitting to the fatigue and recovery characteristics of a photosensitive body due to a pause time or a consecutive operation. CONSTITUTION:To a microcomputer 20 which controls the static elimination lamp 27 of a photosensitive drum, a ROM 21 in which a control program and a duty factor table are stored, counters A-C, and a RAM 22 on which a flag and a timer are set are connected. And the time of the consecutive operation is measured while it is performed, and static elimination light with a quantity decided for a section time to which the time of the above consecutive operation belongs is projected. Since each section time is divided so as to be increased in a unit of index, by setting a light quantity corresponding to each section time by reducing gradually, the static eliminating light quantity is decreased in a unit of logarithm. Also, even when the next operation after pause is started, the static eliminating light quantity decided on the section time to which the length of the pause time belongs can be set. In such a way, it is possible to uniformize a fatigue state at the time of electrification and to stabilize the electrification potential.

Title: Optical information reproducer
Inventor: OKADA KAZUO
IPC: G11B7/1365
Filed: 1982-10-14
Abstract: PURPOSE:To improve the S/N of a reproducing signal, by feeding back a part of the reflected light from a recording medium to a semicnductor laser. CONSTITUTION:The phase of a phase plate 25 is shifted by a prescribed amount from lambda/4 (lambda is wavelength) so as to feed back about 5-15% of the reflected light from a disc 8 to a semiconductor laser 1 at all times. When the luminous amount to be fed back is 5% of the reflected amount, a 0.21lambda or 0.20lambda phase plate is used by a shift of 0.04lambda from lambda/4, i.e., 0.25lambda, and when 15%, a phase plate of 0.19lambda or 0.31lambda is used by a shift of 0.06lambda. Thus, in feeding back a prescribed amount of the reflected light to the semiconductor laser 1 of single mode, the longitudinal mode of the semiconductor laser 1 of longitudinal single mode has a property to be converted into the multi-mode. Since the multi-mode indicates spread spectrum width of the laser light equivalently, the interference at the inside of the semiconductor laser 1 hardly takes place and the generation of noise is reduced.

Abstract: PURPOSE:To easily set the time needed for an automatic circuit opening action through a re-originating action by providing a button input deciding means which decides the one of a group of buttons and a busy tone detecting means which opens automatically a trunk line in a busy mode. CONSTITUTION:A button input deciding means 5a decides the push of a start button 2a and a circuit closing circuit 3 is started. Then the push of numeric buttons 2b also decided by the means 5a and a dial originating circuit 4 is started. If the remote station is kept in a busy mode, a busy tone detecting means 5b opens automatically a circuit. At the same time, a timer means 5c is started and the buzzer tones are outputted through a buzzer circuit 6 after a fixed time. When a re-originating button 7 is pushed after transmission of buzzer tones, a re-originating operation is given to the remote station of a busy mode after the circuit is closed. Thus it is possible to close again a trunk line and to give the second originating operation automatically to the remote station kept under a busy mode just by having a simple button operation after a desired fixed time.
