Title: Short-circuit protective circuit
Inventor: GOORABU MAJIYUUMUDAARU
IPC: H03F1/52
Filed: 1987-04-27
Abstract: PURPOSE:To reduce a whole circuit by detecting an overcurrent without using a current transformer or a current shunt. CONSTITUTION:A switching element 1 for supplying a current to a load is controlled by a driver 2. When an overcurrent flows to the element 1, a high side voltage of the element 1 is abnormally raised. This voltage is applied to a voltage detector 3, and a voltage is generated across a resistor 7 by the current. This voltage is compared by a voltage comparator 4 with the voltage of a reference voltage source 5. If it exceeds it, the comparator 4 feeds a signal to a driver controller 6 to turn it ON, thereby reducing the high side voltage of a resistor 13 to turn OFF a driving transistor 12. Thus, the driving signal of the switching element is interrupted.

Title: Method of changing pitch
Inventor: ASANO TAKAYASU
IPC: B65G49/07
Filed: 1989-04-25
Abstract: PURPOSE:To obtain an apparatus of a simple structure and easy to handle and capable of stepless pitch change by changing the pitches between holding units by controlling the expansion and contraction of an elastic body. CONSTITUTION:In changing the pitch by changing the interval after the distance from a panel W is held at the specific pitch interval, the pitches between holding units 20 are changed by controlling the expansion and contraction of an elastic body. Connecting the positions of each point, set at regular intervals, of the stretcher-shaped elastic body with each holding unit 20 and applying tensile or compressive force to the elastic body moves each point by an equal distance to change the intervals by an equal range. Therefore, the pitches between the holding units 20 connected to the points set at regular intervals are changed to perform pitch changing. This enables stepless change of the arrangement pitches of the holding units 20 and the pitch of the panel W held by the holding units 20.
