Title: Speed change control device for tractor or the like
Inventor: TAMAI SEISHIN
IPC: F16H61/16
Filed: 1988-12-28
Abstract: PURPOSE:To improve safety and controllability with a speed change gear smoothed in its on-operation by providing a neutral control device assigning a neutral position by a neutral switch, continuously placing a clutch in its disconnection position for the fixed time and actuating the speed change gear to the neutral position. CONSTITUTION:When a neutral switch 1 in a control part 26 is turned on, a neutral control device 4 places a clutch 2 in a disconnection position over the fixed time, actuating a speed change gear to a neutral position, and the clutch is placed in an in-position. These interlocking controls are performed by a controller 25 in its CPU control of the device 4. In this way, safety and controllability can be improved by enabling on-operation to be smoothed of the speed change gear.

Title: Mos-type transistor having integration-protecting zener diode
Inventor: JIYAN JIMEN
IPC: H01L27/02
Filed: 1992-11-20
Abstract: PURPOSE: To provide a protection circuit to be used for simple integrated structure so as not to complicate manufacture by constituting a 2nd conductive high impurity injection region, which extends from one part of drain region towards a 2nd extremely high impurity injection region, through a 1st low impurity injection region. CONSTITUTION: A breakdown voltage Zener diode is formed by an interface between regions 9 and 6. Thus, a contact between a drain region 3 and a p<+> -layer 6 is a high impurity injection N-type region 9, and a breakdown voltage can be selected to be high. Further, since it seems that carriers generated by an avalanche are not likely to be pulled by a gate, the Zener diode is considerably broken down from a surface, when generating a surge current at a terminal A. Since such a transistor has a comparatively wide surface area, electric charges from the surge current can be discharged quickly.
