Title: Display driving circuit
Inventor: YUKI OSAMU
IPC: H04N5/66
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To prevent an image persistence and after-image phenomenum by providing a driving circuit with a means for inverting the polarities of video signal voltages at every two horizontal scanning periods and a means for shifting video signal polarity inversion signals for one line. SOLUTION: The video signals inputted to a signal switching device 7 for the one line are first stored in a first line memory 1. When the storage is completed in one horizontal synchronizing period of television signals, connection is switched by a memory switching signal and the video signals for the next one line begin to be stored in a second line memory 2. Simultaneously therewith, the video signals begin to be read out in a period half the one horizontal scanning period from a first line memory 1 and the video signals for the two lines are supplied to a liquid crystal display device.  At this time, a signal polarity controller 3 receives the signal from a video signal polarity switching signal generator 4 inverted in the one horizontal synchronizing period of the television signals, i.e., the two horizontal scanning periods of the liquid crystal display device and inverts the polarities of the video signal voltages every two lines.

Title: Heating tip apparatus and temperature control method of heating tip
Inventor: OSHIMA MASAAKI
IPC: H01L21/52
Filed: 1990-07-26
Abstract: PURPOSE:To prevent the abnormal temperature rise of a heating tip by receiving the output of a temperature-detecting thermocouple to monitor the temperature of the heating tip and by temperature-controlling the heating tip on the basis of the output of a temperature control thermocouple and the monitor results of a monitoring device. CONSTITUTION:When e.g. a temperature control thermocouple 7 comes off a heating tip 3, it is difficult to conduct an accurate temperature detection by the temperature control thermocouple 7. Also, the temperature control thermocouple 7 outputs a signal indicating a low temperature to a controller 8 irrespective of the temperature of the heating tip 3. Consequently, the heating tip 3 is supplied with a high current corresponding to the output of the temperature control thermocouple 7 to rapidly rise in the temperature, but the temperature of the heating tip 3 is detected by a temperature-detecting thermocouple 9 and monitored by a monitoring device 10. Then, when the temperature of the heating tip 3 reaches the upper limit of a preset range, the monitoring device 10 gives the controller 8 the output that the temperature has reached the upper limit. After that, the preset temperature-detecting contact of the controller 8 operates so that the conduction to the heating tip 3 is intercepted and the abnormal rise of the temperature of the heating tip 3 is hindered.

Then the detection data of the detection part 12 is inputted to the memory 5b of the control part 5 and a position signal of a specific position judged as a specific flaw is read out and supplied to the controller 4. Consequently, the motors 2 and 3b are driven to move the specified position into the visual field of the microscope 6 and the position is picked up by a camera 7. Thus, the material to be inspected is inspected rationally.

Title: Printing head for dot impact printer
Inventor: ITATSU KISHIHARU
IPC: B41J2/235
Filed: 1990-07-25
Abstract: PURPOSE:To achieve a reduction in noise with a decrease in return impact by dividing plate springs each with a slight gap between the spring and a stopper rubber into the number same as that of armatures to be formed in a shape of a petal so that both of outer and inner circumference parts of the plate springs are supported to allow a quick rising. CONSTITUTION:A stopper plate 17 is provided with slits same in number as armatures on a disc-shaped plate and given a shape of a petal in no way affecting actions of any adjacent armature 2. A rubber plate 17b is put between two spring plates 17a and 17c and both of outer and inner circumference parts of the spring plates are supported with a stopper 13 so that an action is created to absorb an impact when an armature arm 2a abuts on the stopper plates. Moreover, a gap G is provided between the stopper plate 17 and a stopper rubber 13a and hence, at the start of a printing, a return spring 5 is damped by a spring force of the stopper plate 17 to allow a quick rising of action. This reduces a return impact speed to prevent deformation and wearing thereby achieving a reduction in noise.

Title: Speed control of ac motor
Inventor: TSUMURA TOSHIHIRO
IPC: H02P21/34
Filed: 1986-08-22
Abstract: PURPOSE:To perform continuous speed control from superlow speed, by supplying power to the secondary winding through an inverter. CONSTITUTION:From a commercial power source the voltage at power frequency(f) and voltage E0 is supplied to a stator of a three-phase AC motor AM. On the other hand, the voltage supplied from a commercial three-phase AC power source, as an input, is converted into an DC voltage Ed by a rectification circuit REC. Immediately after that, the DC voltage Ed is converted into the three-phase AC voltage at frequency f2 and voltage E3. Thus an AC voltage is supplied to a rotor through a slip ring of the three-phase AC motor AM. By changing this frequency f2, the speed of the AC motor AM can be made continuously variable from superlow speed.
