IPC: B60L3/00
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To protect a differential gear in a driving device from an overload. SOLUTION: The revolution of the differential case of a differential gear 14 is detected by a differential case revolution sensor 24. The changing rate of the detected revolution is calculated by a motor control unit 22.

Further, when the revolution of the differential case reaches a value lower than a 2nd predetermined value, it is judged that the idling of the driving wheels 18 is dissolved. Then, the output of the motor 10 is released from the limitation and the normal control is restored.

Title: Semiconductor memory
Inventor: SHINOHARA HIROSHI
IPC: G11C11/40
Filed: 1984-10-30
Abstract: PURPOSE:To quickly respond to a signal change by making the length of a gate for load transistors on bit lines and I/O lines greater than that of the gate (channel length) for the transfer gate transistors. CONSTITUTION:The channel length of bit line load transistor 3a and I/O line load transistor 4a is made greater than that of the conventional devices. As the channel length of the field effect type transistor forms a plane geometric shape, the change in channel length can be made only by correcting a photo mask for gate pattern forming without making the manufacturing process complicate. Therefore a selected transfer gate is always in a continuity state, the voltage level on I/O line D lowers rapidly following the change of the voltage level on bit line B. Delay time DELTAt2 is largely shortened.
