Title: Signal detecting circuit for telephone circuit
Inventor: IZAWA SHOJI
IPC: H04M1/00
Filed: 1985-06-28
Abstract: PURPOSE:To detect the polarity inversion of a telephone circuit or a bell ring signal just with a single photocoupler, by connecting a bell ringer circuit and a photocoupler to the output side of a diode bridge which delivers the bell ring signal sent from a telephone circuit to the bell ringer circuit after rectifying it. CONSTITUTION:The signal detecting circuit of a telephone circuit contains a telephone function and a MODEM 15 for information communication. The telephone function contains a diode bridge 21 which rectifies the input signal sent from the telephone circuit and a bell ringer circuit 22 which works by the bell ring signal sent from the telephone circuit connected to the output side of the bridge 21. Then a photocoupler 26 which detects the polarity inversion of the telephone circuit and the bell ring signal is connected to the output side of the bridge 21. Thus the polarity inversion and bell ring signals supplied from the telephone circuit are rectified by the bridge 21. Then the output signal rectified by the bridge 21 is detected by the photocoupler 26.

Title: Rotary type heat exchanger
Inventor: SAKAI TSUNEKO
IPC: F28D11/04
Filed: 1982-08-18
Abstract: PURPOSE:To contrive to realize the favorable distribution of exhaust gas temperature and consequently to eliminate the need to use valuable material as a pipe bar material and yet to prolong the lifetime of the exchanger by a method wherein an inlet side duct for exhaust gas passage is eccentrically attached to the rotatable heat exchanger main body and an outlet side duct is concentrically attached thereto. CONSTITUTION:Exhaust gas enters at an a-1 side and discharges through the interior chamber 41 of the heat exchanger main body 10 from an a-2 side. In this case, the rotation of the heat exchanger main body by 10 degrees causes the exhaust gas to produce violent turbulent flow in the interior chamber 41 and to move in delicate and complicated manner, resulting in increasing the heating surface areas of a pipe bar 11 bundle. Because the inlet side duct 39 for exhaust gas passage is eccentric to the heat exchanger main body 10 by the eccentricity of (e), the exhaust gas flow passage takes a rising course as indicated with arrows or from a-1 to a-2. However, because the pipe bar 11 bundle revolves in the direction as indicated with the arrow 42, the exhaust gas in the high temperature zones (a) and (f) are pushed downward on the whole, resulting in eliminating the temperature difference and consequently uniformizing the temperature within the interior chamber.

Title: Broaching machine for lathe turning
Inventor: TAMURA KEISUKE
IPC: B23D39/00
Filed: 1992-05-07
Abstract: PURPOSE:To suppress vibration during processing a work W so as to prevent generation of chattering in a broaching machine for lathe turning. CONSTITUTION:An accerelation sensor 11 is provided in a broach 9, an actuator 12 and an error accerelation sensor 13 are provided in a broach 10, and each of them is connected to a computing element 14. Work W is attached to a main shaft 8 to rotate so that the work W is cut by making the broaches A, B move to the opposite direction of the rotation tangent of the work W. Vibration during processing of the work W is detected by the accerelation sensor 11 and a control signal antiphase to the vibration is generated by the computing element so as to operate the actuator 12, leading to vibration of the broach 120. The vibration of the work W and the broach 10 are absorbed each other, the remained vibration is detected by the error acceleration sensor 13 to be fed back, and the vibration of the broach 10 is compensated through compensation of the control signal so as to be antiphase to the vibration accurately during processing of the work W. Thus the vibration during processing of the work W is suppressed by absorbing completely in the vibration of the broach 10.

Title: Electronic watch with automatic time correcting function
Inventor: TOOYAMA NOBUO
IPC: G04G5/00
Filed: 1978-11-20
Abstract: PURPOSE:To make high-accuracy time adjustments by putting a time corrector, including a time-signal discriminator circuit and second directing reset-to-zero circuit, into operation at least once a month and then by automatically making a second-digit correction in accordance with a time signal. CONSTITUTION:Once the contents of counter circuit 4 of watch circuit 1 reaches fixed time, timer circuit 10 starts counting one-second pulses from divider circuit 3 and also sends an operation command to time signal discriminator circuit 8 at the same time to place circuit 8 and microphone 7 in operation mode. On arrival a time tone at microphone 7, discriminator circuit 8 discriminates that to generate a pulse, which is sent to 30-second directing reset-to-zero circuit 9, thereby correcting the contents of counter 4 to correct time. As a result, an automatic second-digit correction is made at least once a month, and consequently an accurate time adjustment requiring no complicate operation can be made.

IPC: B41J2/355
Filed: 1986-06-18
Abstract: PURPOSE:To miniaturize a power source and to increase a printing speed, in performing printing, by increasing a black ratio value counted by a black ratio counter as printing data counted by a data quantity counter increases. CONSTITUTION:When a black ratio is high, the black ratio of printing data read out from a buffer 5 for printing is high over regions 1-n and, therefore, current supply heating is applied to a thermal head 2 at every divided regions 1-n to perform the printing. When the black ratio is low, the printing is performed successively at every plurality of regions wherein regions 1-n are collected. When a part of a high black ratio and a part of a low black ratio are mixed, the printing is successively performed at every region with respect to the part of a high black ratio, and the printing is performed at every region wherein plural regions are collected with respect to the part of a low black ratio. Then, in a mode following the quantity of the printing data stored in the buffer 5, the value of the black ratio performing printing collectively is corrected. By repeatedly performing printing by collecting regions where the black ratio is counted, the capacity of a power source can be efficiently utilized and a high speed printing can be performed.

Title: Abnormal discharge preventing circuit for discharge device
Inventor: TABATA YASUYUKI
IPC: H05F3/04
Filed: 1993-05-24
Abstract: PURPOSE:To prevent abnormal discharge and improve safety by conducting momentary forced earthing at the transition level before a discharge current is transferred to abnormal discharge level. CONSTITUTION:A pulse transformer 10 has secondary coils 10b connected to the gates of a plurality of thyristors 6, and pulses according to the build up and trailing of the output voltage of a level detecting circuit 8 are outputted from a gate pulse generating circuit 9 to a primary coil 10, and supplied to the coil 10a. Then, gate pulses are supplied from the coils 10b to the gates of the thyristors 6 at once, and all the thyristors 6 are simultaneously ON before generating an ignition discharge. Since a high voltage applying route 5 extending from a DC high voltage power source 4 to a discharge electrode 3 is thus forcedly earthed through the thyristors 6 before the generation of the ignition discharge, the voltage of the electrode 3 is momentarily lowered to O to prevent the ignition discharge, and safety can be improved.

Title: Heat fixing device
Inventor: MENJIYOU TAKESHI
IPC: G03G15/01
Filed: 1984-07-10
Abstract: PURPOSE:To reduce the electric power consumption and to attain stable back heating by controlling the temperature of a fixing roll in case of monocolor copy and controlling the temperature of a pressuring roll in case of full color copy. CONSTITUTION:Since the quantity of toner is large in case of full color copy, a heater 8 is controlled by the thermistor 9 of a pressuring roll 3 to heat the roll stably from the rear face of a transfer material, and the multilayered toner is fused sufficiently. Since the quantity of toner is small in case of monocolor copy, the temperature of a fixing roll 2 is controlled by a thermistor 7 to reduce the heating temperature of a heat roll 1 brought into contact with the rear face of the transfer material, and the power consumption is reduced. Thus, the power consumption is reduced in case of monocolor copy, and back heating at a stable temperature from the rear face of the transfer material is performed in case of full color copy.
