Abstract: PURPOSE:To reliably transmit lever operation to a speed change gear by engaging an operating lever with two bevel gears disposed opposite to each other through a clutch body adapted to move forward and backward, and turning both bevel gears to accomplish speed change of the speed change gear. CONSTITUTION:Two bevel gears 16, 17 are connected to the end portion of an operating lever 11 through a clutch body 19 adapted to move forward and backward. Both bevel gears 16, 17 are disposed opposite to each other, and respectively engaged with an operating bevel gear 15. When the operating lever 11 is moved forward and backward, the movement is transmitted to a forward- backward movement switching device, and causes a clutch body 19 to move to be connected to either of the bevel gears 16, 17. When the operating lever 11 is moved from side to side in such a condition, one of the bevel gears 16, 17 is turned to transmit operating force to a speed change gear through the operating bevel gear 15.

Title: Semiconductor memory element
Inventor: HAYASHI YUTAKA
IPC: H01L29/792
Filed: 1989-10-05
Abstract: PURPOSE:To enable data to be rewritten at a high speed and to make a rewrite voltage low so as to enable a memory element of this design to approximate to a RAM by a method wherein the memory element is so structured as to have a specific energy band diagram characteristic conforming to the structure of a semiconductor memory element in which data is electrically rewritable. CONSTITUTION:A first conductive region E is negatively biased, whereby electrons are injected from the first conductive region E into a carrier trapping region C taking advantage of the change of the conduction band end of a second wide gap region D in average gradient. Then, when the bias is removed from the region E, a band profile reverts as shown in the Figure, so that injected electrons can be kept in a well correspondent to the carrier trapping region C and a memory stored after one of binary logical values is written can be realized. On the contrary, when the first conductive region E is positively biased, holes are injected from the region E into the carrier trapping region C through the intermediary of the second wide gap region D to potentially neutralize the previously stored electrons. Thereafter, when the bias voltage is removed from the region E, a band profile reverts as shown in the Figure and the stored logical value is electrically erased.

Title: Insulating substrate for semiconductor
Inventor: KAKIHARA YOSHINOBU
IPC: H01L21/205
Filed: 1985-11-19
Abstract: PURPOSE:To facilitate the handling of an Si substrate and to obtain an insulating substrate for semiconductor with good reproducibility by providing a thin oxide single crystal film on the Si substrate through a thin single crystal AlN film. CONSTITUTION:A thin AlN single crystal film 2 having a thickness of 10Angstrom -1mum is adhered on an Si substrate 1 by sputtering and so on for obtaining a highly insulative thin film to withstand a high temperature. A film of stabilized zirconia or the like is formed on this in a thickness of 0.1-10mum or thereabouts by a sputtering method and so on. Since the AlN film can be formed in an O2-free atmosphere, the oxide film 3 to be formed after that can be epitaxially grown without oxidizing the surface of the substrate 1. As the stabilized zirconia (ZrO2.Y2O3) film can withstand a high temperature, is stable to active H as well and its lattice mismatching with the Si substrate is also small, an SOI substrate having little defect can be formed in high purity.

Inventor: HOYA MAKOTO
IPC: A63F7/02
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To prevent the malfunction of a sub substrate operated by receiving data even when a signal line for transmitting the data only in one direction by a parallel system is short-circuited. SOLUTION: A start mark 31 is turned to 15h(10101B) for which the data of 5 bits including a D4 bit are set and reset every other bit. In the meantime, an end mark 35 is turned to 1Ah(11010B) for which the D4 bit is set and the 4 bits of the other D3-D0 bits are inverted from the start mark 31. Thus, when the signal lines for transmitting the data are arrayed similarly to the bit array of D4-D0, in the case that the respective signal lines are disconnected or short- circuited the start mark 31 and the end mark 35 can not be normally received on the sub substrate. Thus, the malfunction of the sub substrate by erroneous data is prevented.
