IPC: H02N2/00
Filed: 1993-09-06
Abstract: PURPOSE:To enable reduction of the number of components and the number of assembling steps by a method wherein a support and guide part having a function of supporting and guiding a moving body and a function of preventing a lateral movement, a vertical movement, etc., of the moving body is molded monolithically with a rail-shaped fixed piece. CONSTITUTION:A rail-shaped fixed piece 28 is fixed to a structural member 21 and extends in a straight line. As to the rail-shaped fixed piece 28, a large number of rail-shaped fixed pieces can be made to have the same precision by extrusion or drawing. A support and guide member (SE) 28C for supporting and guiding a moving body 4 is molded monolithically with the fixed piece 28. An engagement part 20 fixed to the moving body 4 has a recessed curved surface 20a being fitted slidably relatively on a columnar outer peripheral part of the SE 28C and a movement in the vertical direction and a movement in the lateral direction of the moving body 4 are restrained by the member 28C and an engagement member 20C. Since the SE 28C for supporting and guiding the moving body 4 is constructed by monolithic molding with the rail-shaped fixed piece 28, accordingly, the number of components and the number of assembling steps can be reduced.

Title: Driving circuit of switching transistor
Inventor: MATSUMOTO HATSUO
IPC: H03K17/04
Filed: 1982-12-21
Abstract: PURPOSE:To prevent the ineffective consumption of driving power for a period up to the cut-off of a switching transistor by adding a new switch element. CONSTITUTION:A switch element SW2 is newly added between the base of a switching transistor TRQ1 and a base resistance RB. This switch SW2 is cut off synchronously with the conduction of a switch SW1, and therefore a current Irb flowing through the resistance RB is cut off in a period during which the switch SW1 starts to conduct and the TRQ1 is cut off. As a result, only the current obtained from the stored electric charge flows through the SW1 via a resistance Rn. This can eliminate the loss of driving power which is caused in the storing period of the TRQ1. In such a way, it is possible to prevent the ineffective consumption of driving power for a period up to the cut-off of the TRQ1.
