Patent JP-H01181344-A (JP)
Title: Radio communication system
Inventor: TEJIMA SHUNICHIRO
IPC: H04J4/00
Filed: 1988-01-14
Abstract: PURPOSE:To miniaturize the transmitter of a peripheral station by devising the peripheral station such that the station transmitting a data signal and a voice signal in parallel simultaneously processes the voice signal into a burst signal and transmitting the data signal and the voice signal in frequency division. CONSTITUTION:Modulators 10, 17 constitute modulation means modulating carriers 1, 2 in different frequencies f1, f2 from a data signal subjected to packet processing and a voice signal subjected to burst processing, and a timing control section 7 and a switch 12 constitute a transmission control means as a whole. In case of the parallel and simultaneous transmission of the data signal and the voice signal from the peripheral station to the center station, the peripheral station uses different carriers 1, 2 from the data and voice signals, but the peripheral station taking an optional point of time switches the carrier so as to transmit only one carrier of either of the modulated carrier 1 relating to a data signal or the modulated carrier 2 relating to a voice signal, that is, in frequency division. Thus, it is not required for the peripheral station to amplify the plural carriers 1, 2 simultaneously. Thus, the transmitter is not necessary to be of high output type and miniaturization is realized.

Abstract: PURPOSE:To enable a waste toner containing vessel to be mounted surely and accurately detect the predetermined amount of the toner by mounting and dismounting said vessel to and from a body by means of a magnet and providing a means for detecting the mounting and dismounting thereof. CONSTITUTION:A rubber magnet 12 of weak magnetic flux is provided on the circumferential surface of the opening of a waste toner containing vessel 9, and is attracted to the iron-made catches 15 buried in toner conveying path members 13, 14, whereby the vessel 9 is mounted to the body. Also, a toner amount detecting means consisting of a luminous body 18 and a photodetector 17 is provided. When with this constitution the toner reaches the predetermined amount and its weight overcomes the attraction force of the magnet, the vessel 9 drops in the direction A. At this time, a photoconductive hole 19 opens and the photodetector 17 operates, thereby stopping the machine and indicating this to the user. This makes the mounting of the vessel 9 sure, eliminates the scattering of the toner because of the close contact at the joint and permits the accurate detection of the toner weights.

Title: Driving circuit of electromagnetic operating device
Inventor: YAKURA TOSHIAKI
IPC: G05B11/28
Filed: 1981-01-22
Abstract: PURPOSE: To detect a surge current with high accuracy, by separately providing a surge current detecting resistance.  
     CONSTITUTION: When voltage Vd of an output terminal (d) of a comparator 2 is in a high level, a Tr7 conducts, a current is supplied to a coil 4 of a solenoid valve, voltage Ve appears in an terminal (e) of a driving current detecting resistance 6, and voltage Vf is obtained through an operational amplifier 18. When voltage Va of a control input terminal (a) has been varied, an integrator 15 integrates in the ratio corresponding to a deviation of this voltage and Vf, and outputs voltage Vb to an output terminal (b). On the other hand, an output Vc from a triangular wave oscillator 10 is compared with Vb, and in case when Vb is larger, the Tr7 is turned on. On the contrary, in case when Vc is larger, a low level signal is outputted and the Tr7 is turned off. In this case, a surge current generated in the coil 4 of the solenoid valve flows through a surge current detecting resistance 31 and a diode 16, and voltage Vg generated in the resistance 31 in that case is inputted to the amplifier 18 through a voltage divider.

IPC: F23N5/24
Filed: 1983-01-20
Abstract: PURPOSE:To close a fuel supply solenoid valve at extinguishing of flame regardless of the output of a microcomputer so as to perform a fail-safe operation by a method wherein at least one pair of flame detection circuits are provided and the output of the one circuit is connected to the input of the microcomputer and the output of the other circuit is connected to a valve circuit. CONSTITUTION:When cooking is started by opening a timer switch 32, the outputs O1 and O2 of a microcomputer 2 remain to be high for a certain fixed period of time, resulting in turning transistors 24 and 25 ON and consequently energizing a light emitting diode (LED) 23, opening a solenoid valve 28, and performing the ignition action of a gas burner 9. When the ignition is established, the field effect transistor (FET) 12 of a flame detection circuit 13 cuts-off so as to output a ''flame on'' signal to an input I1 and the outputs O1 and O2 are kept on outputting to be high even after the elapse of said certain fixed period of time. If the outputs O1 and O2 are high at extinguishing of flam flame due to the abnormal function of the microcomputer 2, a capacitor 19 is charged due to the FET15 of the other flame detection circuit 14 being ON so as to turn ON a transistor 21 and then to turn OFF a transistor 24 through a Zener diode 22 in order to stop the supply of power to the LED23.

Title: Color electrophotographic device
Inventor: NAKAMURA MASAHIKO
IPC: G03G15/08
Filed: 1994-01-28
Abstract: PURPOSE:To provide a compact color electrophotographic device having a simple constitution, capable of obtaining a beautiful color image, and being excellent in maintainability. CONSTITUTION:The group of plural image forming units having toner whose color is different, is wholly rotatively moved, and the respective units are successively moved to the same image forming position. At the image forming position, the image is formed by signal light 13 in the image forming units 1BK, 1C, 1M and 1Y, and the toner image is transferred to an opposed intermediate transfer belt 32. When the toner image on the belt 32 passes a transferring position other than the transferring time, all the image forming units have moved rotating, so that they do not exist at the transferring position. While the toner image on the belt 32 passes the transferring position, the group of the image forming units moves rotating. A photoreceptor 9 and the belt 32 are made to perform the action to come into contact with and to separate from each other at the part on the belt 32, where the toner image is not formed. By controlling the timing of restarting the movement after stopping the rotative movement of the group of the image forming units halfway, the timing of making the belt 32 come into contact with the photoreceptor 9 at the time of completing rotative movement is controlled.

Inventor: KAWAMURA HIDEAKI
IPC: H03F3/68
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption and noise at an oscillating circuit and a semiconductor integrated circuit. SOLUTION: This oscillating circuit 1 is connected with an oscillator 2 and incorporated into a semiconductor integrated circuit 3. At least three-stages of amplifiers A1 to A3 are connected between two input terminals and an output terminal XOUT. In order to reduce the peak current value of the oscillation circuit, a phase shifting circuit C is provided at a node connecting between amplifiers A2 to A3 of a second stage and after if among amplifiers A1 to A3. This phase shifting circuit C shifts the phase relation of the amplifier A2 which is arranged in the prestage and the amplifier A3 which is arranged in the poststage. As a result of it, at two amplifiers, where the phases of peak currents are match and when there is no phase shifting circuit, the peak currents are prevented from overlapping.  Since the peak current value of an oscillation circuit itself is reduced as a result of this, the increase in power consumption by the elevating of the peak current value is suppressed to reduce noise components.
