Title: A grinder
Inventor: INOUE KIYOSHI
IPC: B24B1/04
Filed: 1977-11-25
Abstract: PURPOSE:To improve processing performance and increase grinding speed twice as high by applying oscillation pressure by operating large-amplitude low-frequency oscillation. CONSTITUTION:Ultrasonic wave oscillation generated by ultrasonic wave oscillator 1 is applied to tool 4. Object being processed 5 is ground and processed by grinding grains provided at the end of tool 4. At this time, tool 4 is further given oscillation pressure by electromagnet oscillator 7, which oscillates at low frequency (10- 50Hz). In this way, by giving tool 4 oscillation-varying pressure, processing effects are remarkably enhanced.

Filed: 1986-06-18
Abstract: PURPOSE:To reproduce an image having an aspect ratio longer in side than that of a conventional NTSC system television receiver by forming a television signal including the image information in which the aspect ratio is larger than 4:3. CONSTITUTION:An original image signal, in an image separating circuit 2, is separated to a main image signal YM composed of the image of an area M and a sub-image signal YS composed of the image of the area shown by a slanting area S. The main image signal YM is an image signal having the same aspect ratio (4:3) as the conventional NTSC system. The main image signal YM is supplied to a time base multiplex circuit 4, the sub-image signal YS is supplied to an orthogonal converting circuit 3, and in the orthogonal converting circuit 3, the sub-image signal YS is converted onto a space frequency axis. A low order sub-image signal YSL with a high energy is supplied to the time base multiplex circuit 4 and a high order sub-image signal YSM with a comparatively low energy is supplied to a frequency axis multiplex circuit 5. Thus, while the compatibility is kept with a conventional NTSC system, image information having a wide aspect ratio can be transmitted.

Title: Arc welding method
Inventor: MITA TSUNEO
IPC: B23K9/173
Filed: 1981-09-11
Abstract: PURPOSE:To expand the range of adaptation by changing the waveforms of pulse currents to be superposed on base current thereby improving the stability of the arc in a small current region and decreasing an average welding current value of a lower limit. CONSTITUTION:The 1st pulse trains P1, P3 having a uniform period T are generated, and the 2nd pulse trains P2, P4 are generated with delay of a certain time (t) (t<T/2). The reference pulse trains P1, P3 and the delay pulse trains P2, P4 are superposed on base current IB. With the superposed currents as welding current, arc welding is executed. Then, for example, when a droplet is transferred to base materials at the reference pulse P1, the delay pulse P2 preheats a welding wire, and assists the transfer of droplets at the pulse P3 right thereafter. If the droplet fails to transfer at the pulse P1, the droplet can be transferred at the pulse P2 right thereafter. As a result, the excessive growth of the  droplet is prevented, and the sure transfer of the droplet with lower current is  made possible.

Title: Inverter device
Inventor: SUMIYA NAOYUKI
IPC: H02M7/66
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To prevent a capacitor from puncturing even if an induced voltage generated by a motor is accumulated in the capacitor, and to prevent malfunction to be caused by noise. SOLUTION: An inverter device is provided with a motor 17 which generates an induced voltage, an inverter 15 connected with the motor, and a capacitor 13 connected with the motor via the inverter. The motor 17 and capacitor 13 are structured in such a way as to be electrically disconnected with a means of stopping the accumulation of the induced voltage, if the voltage value of the inverter exceeds the withstand voltage value of the capacitor, and if the rate of change of the current across the connection terminals at power supply side becomes lower than that of a reference current. Because the supply of the induced voltage to the capacitor 13 is turned off by detecting the occurrence of an abnormality in the inverter circuit, the voltage of the capacitor 13 never exceeds its withstand voltage. Thus, it is possible to protect the capacitor 13.
