Title: Hot line inserting/disconnecting circuit for printed board
Inventor: FURUKUBO YUJI
IPC: H05K7/14
Filed: 1990-03-06
Abstract: PURPOSE:To prevent the generation of a voltage drop in an adjacent slot even at the time of inserting a hot line into a printed board by independently setting up power supply buses on a mother board correspondingly to respective printed board slots. CONSTITUTION:The mother board 2 and printed boards S1 to Sn to be connected to upper connectors are stored in a card frame 1. A power supply bus 3 is connected in the board 2 to supply power supply voltage to respective substrates S1 to Sn. The bus 3 consists of (n) minibuses 31 to 3n and respective substrates corresponding to respective buses 31 to 3n are prepared. A power supply device 4 supplies a necessary power supply voltage to the common part of the bus 3. Even when a rush current due to a power supply by-pass capacitor is generated at the time of inserting a certain printed board, only the voltage of the minibus supplied to the power supply voltage to the board is sharply dropped and a voltage drop level on the common part of the bus 3 and other minibus parts is small. This is because the common part has a thick pattern and small impedance against the minibus lines.

Abstract: PURPOSE:To prevent a glass body, which is arranged in the peripheral wall of a heating cylinder, from breaking and improve the sealing effect of the glass body by a method wherein the cylindrical glass body is agreeably arranged in a circular hole, which is axially bored in the peripheral wall of the heating cylinder, so as to be able to visually recognize the interior of the heating cylinder through the glass body. CONSTITUTION:In the peripheral wall of a heating cylinder 1, a long circular hole 13, which axially runs from one end to nearly the other end of the heating cylinder, is continuously bored. Cylindrical glass bodies 17, the cross-section of each of which agrees to the circular hole 13, are arranged into the circular hole. A plurality of axially long observation windows, each of which runs from the outer surface of the peripheral wall of a cylinder 3 to the circular hole 13, and of axially long notches 16, each of which runs from the inner surface of the peripheral wall of the cylinder to the circular hole 13, are separately provided on the same line. Since the cylinder 3 is not split, no seal for split surface is unnecessary and sealing effect becomes favorable. Even when the glass body is pushed by resin pressure against the inner surface of the circular hole 13 at its outward side, the circular hole 13 and the glass body 17 are urged through circular arcuate surface to each other, resulting in applying no local stress on the glass body and preventing the glass body from breaking.

Abstract: PURPOSE:To downsize the motor section by employing a step structure in which the inner diameter of yoke at a part corresponding to a holder plate system including a brush is set larger than the inner diameter of yoke constituting the motor profile. CONSTITUTION:Stator of motor 44 comprises a yoke 43 and a field pole 51. The yoke 43 is constituted such that the inner diameter at the brush fixing side end 43b and the reduction gear fixing side end 43c is larger than that at the field pole fixing section 43d. When the inner diameter of the yoke 43 constituting the profile of the motor 44 is extended as required to provide an axially stepped structure, the field pole fixing section 43d of the motor 44, i.e., the yoke 43, can be downsized. Furthermore, since the brush 62 is ensured to be longer than a predetermined length it can be freely regulated in length according to the durability of the motor 44, resulting in enhancement of reliability. At the same time, only the motor 44 can be downsized except such parts as reduction gear system 13 which is difficult to downsize in view point of strength.
