Title: Method for treating surface hardening of piston ring
Inventor: TAKAHASHI KENJI
IPC: B23K26/352
Filed: 1986-10-28
Abstract: PURPOSE:To restrain the development of strain and to enable continuous hardening treatment by alloying or chilling sliding face of a piston ring by using heat source having high energy density, and forming hardened layer as zigzag state, etc., in the range on the sliding face except the edge part thereof. CONSTITUTION:While rotating the piston ring 1, the heat source 8 having high energy density, such as laser, TIG arc, etc., is reciprocatively scanned on the sliding face 2 zigzag-state, waving-state or spiral-state at the prescribed cycle. In this way, the hardened layer 3 is formed zigzag-state in the range on the sliding face 2 except the edge part thereof. By this treating method, the hardened treatment is executed under good balance on the whole sliding face 2 and the development of strain is restrained. Further, as continuous treatment can be executed in one operation, the treating time is remarkably shortened.

Title: Magnetic recording and reproducing device
Inventor: SAITO KOJI
IPC: G11B15/24
Filed: 1989-09-29
Abstract: PURPOSE:To drastically shorten the time for shifting a stop mode to a recording or reproducing mode by providing a means for rotating a capstan in the forward direction for a prescribed period of time, reversing afterward the capstan by a prescribed revolving amt. and shifting the device into the standby state. CONSTITUTION:When the stop mode is set, a mechanism is set in the same state as the reproducing or recording mode, the capstan 35 is rotated in the forward direction for a prescribed period of time and then reversed by a prescribed amt. Consequently, when the stop mode is set, a tape 22 is fed slightly in the direction of an arrow A and then brought back in the reverse direction (the direction of an arrow B). As a result, the tape 22 becomes under a slackened state against a cylinder 33 in existence on the way of the tape. Therefore, similarly to the recording or reproducing mode, even when the cylinder is kept rotating, neither abrasion nor clogging takes place on a video head by its strongly abutting against the tape. By this method, the time for shifting from the stop mode to the recording or reproducing mode can drastically be shortened.

IPC: G02F1/133
Filed: 1988-10-12
Abstract: PURPOSE:To drastically decrease crosstalks by assigning square waves one period of which is the selection period of scanning electrodes as the data signal to be supplied per picture element so that the phases thereof are reversed at on and off. CONSTITUTION:The square waves of one period are assigned in accordance with on and off of display information to the waveform of the data signal SC to be supplied to a 1st display electrodes 4. The phases of the waves are reversed at the on and off. The scanning signal SW to be supplied to a 2nd display electrodes 6 is the waveform the level of which has steps in accordance with the square waves in the selection period Ta. The signal is driven at the specified level in a bias period. The display data to one picture element in this driving method is the square wave and the phases are reversed at the on and off; therefore, the impressed voltage fluctuates by + or -VC around Vb at all times even if all the picture elements of the other one row exclusive of the desired picture elements turn on or off. The impressed voltage in the bias period is, therefore, averaged and does not depend on the contents of the display. Namely, the fluctuation in brightness arising from the difference in the display contents is substantially eliminated.

Title: Degaussing circuit
Inventor: YASU SHIYOUKI
IPC: G11C11/409
Filed: 1993-10-14
Abstract: PURPOSE: To prevent power consumption and the rise in ambient temperature by controlling alternating currents flowing to a positive-temperature-coefficient resistance and a demagnetizing coil. CONSTITUTION: With a switch 31 ON, AC power is applied to a rectifying circuit 1 and converted into a direct current. This direct current is smoothed by a capacitor 33 and then an RC charging circuit 3 charges a voltage in a capacitor 7 through a resistance 6; and a transistor 8 stays ON and a relay 4 also stays ON unit the capacitor is charged up to a specific voltage. At the time of power supply, an alternating current flows to the demagnetizing coil 34 through the positive-temperature-coefficient resistance 35 of approximately 20Ω to erase the magnetic field of a monitor or television tube. Then the resistance value of the resistance 35 increases 1 to 2 seconds later and the current of the coil 34 is decreased. As the voltage of the capacitor 7 rises, the relay 4 is turned off associatively.  Therefore, the coil 34 is released and the temperature of the resistance 35 falls and decreases in resistance value, so that the magnetic field can be erased only when the power is supplied to the coil 34. Thus, the power consumption is reduced and the ambient temperature is prevented from rising.
