Title: Method and device for controlling cargo work/ construction machine or the like with joy stick
Inventor: SUZUKI HIROYUKI
IPC: B66C13/56
Filed: 1989-03-03
Abstract: PURPOSE:To reduce the possibility to cause the transmission of an instruction signal for misoperation and to improve the operability by preparing plural additional dead zones adjacently to a central dead zone set around a neutral position where a control lever is set up in order to temporarily delay the working instruction signals to be sent to the working actuators set adjacent to each other. CONSTITUTION:A central dead zone 5 does not respond to the waves or the turnings of a single control lever 2 produced at small angles and set around the position of the lever 2. At the same time, a 1st (X axis) dead zone 11 and a 2nd (Y axis) dead zone 12 having no mutual interference are prepared adjacent to the zone 5 in the same number as the working instruction signal systems. These additional zones 11 and 12 send the working instruction signal received from a potentiometer adjacent to the lever 2 tilted to the zones 11 and 12 with higher priority than other adjacent potentiometers. Thus no inadvertent malfunction is caused at all with the slight waves or turnings of the lever 2. Furthermore a desired operation is attained with only the working instruction signal of a desired actuator even if the lever 2 is shifted aside from its prescribed operating direction.

Inventor: HIRASE JUNJI
IPC: H01L21/336
Filed: 1993-03-11
Abstract: PURPOSE:To provide an insulated-gate type field-effect transistor(FET) using conventional LATID structure as a basis and having high speed properties and high reliability. CONSTITUTION:A low-concentration source 4 and a low-concentration drain 6 are formed in regions, which are adjoined to the high-concentration source 7 and high-concentration drain 8 of an FET and parts of which are positioned to the lower sections of a gate electrode 3. Concentration distribution is formed so that effective impurity concentration is lowered gradually toward the surface section of a substrate from the inside of the substrate in the low-concentration source 4 and the low-concentration drain 5. Consequently, capacitance between a gate and the drain is reduced, and the working speed of a circuit is increased. The generation region of hot carriers is deepened, and hot-carrier resistance is improved. Impurity concentration distribution can be enhanced only by changing the conditions of impregnation and the conditions of heat treatment at a time when the FFT having conventional LATID structure is manufactured in a manufacturing process. Effective impurity concentration on the surface sections of the low-concentration source and drain can be lowered through counter-doping.
