Title: Lubricating device for transfer
Inventor: CHINO AKIRA
IPC: F16H57/04
Filed: 1987-06-05
Abstract: PURPOSE:To prevent an abnormal temperature rise of lubricating oil by scraping up lubricating oil in a transfer case by a tooth surface to be fed into a lubricating oil collecting chamber and lubricating a rotary sliding portion through a supply pipe when the internal pressure in the transfer case increases. CONSTITUTION:When gears 5, 6 built in a front transfer case 2 are driven, lubricating oil scraped up to be carried in the rotating direction is continuously fed into a lubricating oil collecting chamber 10 disposed at the upper portion of a partition wall 9 and filled therein. During operation, when the pressure in the transfer case 2 increases, lubricating oil in the collecting chamber 10 is supplied to a bearing 7 separating from the lubricating oil lever according to an increase in pressure through a supply pipe 13. Thus, the lubricating oil is kept from generating heat due to a large oscillation or collision in its supply process, so that abnormal temperature rise can be prevented.

Title: Crt horizontal deflecting circuit
Inventor: SUGANUMA NOBUTAKA
IPC: H03K4/62
Filed: 1988-06-08
Abstract: PURPOSE:To simplify circuit composition and to decrease a generated loss by using a bipolar mode MOS-FET (IGBT) as a semiconductor switching means. CONSTITUTION:The semiconductor switching means is replaced with an IGBT4, and in the composition of the semiconductor of the IGBT, the junction of P<+>N<->P<+> is composed in a direction from an emitter E to a collector C like the internal part of a silicon substrate 11A, and a parasitic diode does not exist. Consequently, this IGBT indicates the inverse characteristic of high impedance. Therefore, since the generated current of a horizontal deflecting coil LH is surely applied to a damper diode Dd connected to the IGBT4 in parallel even when a reverse-blocking diode does not exist, an operation with a small loss and a frequency as high as the frequency of the MOS-FET can be attained. Thus, a high-frequency reverse-blocking diode, which is necessary at the time of applying the MOS-FET, becomes unnecessary, the circuit composition can be simplified, and simultaneously, a power loss can be minimized.
