Title: Rubber plug for water-proof connector
Inventor: HAYASHI HIROYUKI
IPC: H01R13/52
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To establish water-proof even when bending force acts on an electric wire. SOLUTION: The water-proof rubber plug 3 consists of a seal 7 with outer peripheral lip 8, and a bending receiving part 11 on the back of the seal 7. The bending receiving part 11 is thick and has a taper surface 12 where the outer peripheral surface's diameter increases from its front side to its back side. When an electric wire is bent the bending receiving part 11 receives the bending. Because the bending receiving part 11 has such form that the part 11 is hard to deform, a gap is hard to be formed between the taper surface 12 and an opening edge 1A.  Even if a gap is formed the seal 7 is hardly affected by bending of the electric wire and the outer peripheral lip 8 is kept to fix tightly to the inner peripheral surface of a seal cylinder part 1, because bending angle of the electric wire 2 is limited and the seal 7 is at inner side of the bending receiving part 11 in the direction of axial line. Thus, water-proof is established.

Title: Semiconductor device
Inventor: ISHIDA HIROICHI
IPC: H01L23/50
Filed: 1985-01-24
Abstract: PURPOSE:To contrive to reduce the generation of leakage signals between adjacent lead terminals, by a method wherein a conductor is inserted between adjacent lead terminals of the package, and this conductor is fixed to the earth or a given potential. CONSTITUTION:A semiconductor pellet 11 is mounted by heating the die pad 12 of a package 1, and electrodes 11a are electrically connected to the wire bonding pads 9 of lead terminals 2-4 with conductor wires 10. Further, in order to fix the potential of the die pad 12 to a given potential, the wire bonding pad 9 of a terminal 2 is connected to the die pad 12 with a conductor wire 13. Since this device has the projection 12a of the die pad 12 fixed to the earth or a given potential inserted between the adjacent lead terminals 2-4, a leakage signal going to jump e.g. from lead terminal 4 to lead terminal 3 drops to the projection 12a of the die pad of low impedance, and similarly the leakage signal from the lead terminal 3 is difficult to jump to the lead terminal 4, resulting in the reduction in malfunction of the device.

Filed: 1989-01-20
Abstract: PURPOSE:To enable proper judgement about the completion of document discharge by interrupting the detection of a document while a gap between leading and trailing documents placed before and after a discharge point in an array mode is passing a detecting means for detecting the trailing end of a document. CONSTITUTION:After documents arrayed in line on platen glass 2 in a two-in-one operation mode are exposed to light, a main motor M2 for driving a transfer belt 53 is turned on to operate at a low speed and the documents are thereby discharged to a document discharge tray 12. In this case, a trailing end detection start timer is so made that a detecting sensor S5 does not detect a gap formed between the first and second documents, and set to time necessary for detecting the trailing end of the second document after detecting the first document. Two documents are thereby made apparently a single document for being detected with the detecting sensor S5, and the detected signal causes the start of the next two-in-one mode operation. According to the aforesaid construction, it becomes possible to properly judge whether the documents are completely discharged in the array mode (two-in-one operation mode).

IPC: H05K3/34
Filed: 1990-01-23
Abstract: PURPOSE:To prevent the generation of a bridge between a pattern and an adjacent pattern by forming a linear unsolderable part, which separates each wiring pattern in a length direction, for whole length in a width direction on each wiring pattern. CONSTITUTION:A parting pad is formed by forming an unsolderable part 22 so as to separate a short or strip-shaped pattern (mount pad) 20 approximately in the middle in the length direction. The unsolderable part 22 is formed by linearly applying a solder resist 22 on the mounting pad 20 for the whole length in the width direction. The application of the resist 22 is carried out by applying the resist under the condition that a mask possessing a slit corresponding to the unsolderable part 22 is covered on each mounting pad. Thus, even when a connecting piece at bottom tip of a lead terminal leg extending from an IC package is bent and deformed in a vertical direction, the generation of a bridge between a pattern and an adjacent pattern is prevented.
