Title: Dc motor
Inventor: ISHIZUKA ATSURO
IPC: H02K23/00
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a DC motor capable of reducing vibration without accompa nying increase in weight. SOLUTION: Brushes 5a, 5b for applying a DC voltage to a rotor 3 are arranged asymmetrically with respect to a rotary shaft 31, and brought into elastic contact with commutators 33 arranged at positions symmetric with respect to the rotary shaft 31. The application timing shift of an exciting force is generated by the arrangement shift of both the brushes 5a, 5b, in the current direction inversion when a commutator 32 passes the one brush 5a, and the current direction inversion when the commutator 32 passes the other brush 5b. This timing shift applies an antiphase exciting force to the vibration component of a motor, which corresponds to a phase change of one half cycle, and the vibration component is reduced.

Title: Information recording medium
Inventor: HASEGAWA HARUMI
IPC: G07F7/08
Filed: 1988-08-31
Abstract: PURPOSE:To facilitate a checkup of the use condition of information recording medium and make possible the repeated deletion and writing of any visible information without providing a power supply in the information recording medium by arranging the medium between a liquid crystal layer and a transparent electrode substrate and an optical conductor and displaying information to be recorded as an image. CONSTITUTION:If light hgamma is projected to a photoconductive photosensitive element 13, the volume resistance Rp of the photosensitive element 13 reduces and thereby a voltage Vl applied to a liquid crystal layer 12 increases. In addition, if the light hgamma is not projected to the photoconductive photosensitive element 13, the voltage Vl applied to the liquid crystal layer 12 reduces because the volume resistance Rp of the photosensitive element 13 is highly resistive. Consequently, the light hgamma corresponding to an image is projected and a voltage VDC is applied from outside so that a voltage applied to the white section(exposed section) of an image is VH and a voltage VM applied to the black section(non-exposed section) is VM. Consequently, visible information, that is, a desired visible image can be formed. In addition, this visible image is maintained as it is even after the applied voltage VDC is removed. During non-exposure time, the visible image can be deleted by applying such a voltage VHH that a voltage VL equals VH.

Title: Image forming device
Inventor: OTSUKA YASUMASA
IPC: G03G21/00
Filed: 1984-10-13
Abstract: PURPOSE:To control temp. with high accuracy by executing the power feed to a heater for heating a laser by on and off of pulse current conduction. CONSTITUTION:The signal of a temp. detecting element 26 is transmitted to a temp. regulating circuit 27 and the output of a power source 28 is measured by a voltage detecting circuit 29 and is transmitted to the circuit 27. The circuit 27 interrupts the electric power which the power source 28 impresses to the heater 25 on the basis of the two signals. The quantity of the heat to be generated by the heater per unit time can be decreased by conducting the pulse current in the stage of supplying electric power to the heater 25 in this case and since the generation of a delay in detection in the temp. detecting means 26 is made hard, the temp. ripple of the heater 25 is diminished. The temp. control with high accuracy is made possible by attaching the temp. regulating circuit to change over the ratio between the pulse on time and pulse off time during the conduction of the pulse current in accordance with the power source voltage to be supplied to the heater.

Title: Fault recovery monitoring system
Inventor: MORITA YOSHIO
IPC: H04M3/24
Filed: 1982-12-08
Abstract: PURPOSE:To minitor the recovery of a fault without providing a special transmission line between a master station and a remote line concentrating station, by monitoring the fault recovery at all times by controlling a selection switch with a timing generator and connecting repetitively the communication channel of the transmission line to a PCM transmission line. CONSTITUTION:When a PCM transmission line has a fault, a monitor circuit SUP sends the fault signal to a timing generator TG, microprocessor MPU and a switch SW respectively. The generator TG switches a selection switch SEL and the switch SW toward a dotted line. A connection is secured with an autonomous action device SAE when a master station MOF is viewed from a line concentrator RLC. Thus no interruption is given to the communication between subscribers of a remote line concentrating station. The generator TG controls the switch SEL and switches the SEL toward the solid line side in the timing when a channel emerges. Then the TG transmits or receives (figure C) the signal of channel to the PCM transmission line and also the time slot of a sound channel switches the SEL to the dotted line side (figure B). When the fault is recovered, the data transmission is immediately restarted to the station MOF by a communication channel. In this case, the SEL is switched to the solid line side, and kept as it is.
