Patent JP-H03245923-A (JP)
Title: Insertion device
Inventor: MIYAGAWA TAKESHI
IPC: B23P19/02
Filed: 1990-02-23
Abstract: PURPOSE:To automatically carry out insertion work in a simple manner by installing an advance/retreat mechanism which advances in the forestage of an insertion process for inserting an inserted article into an insertion part and applies rigidity to an insertion member by supporting the top edge part of the insertion member and retreats in the posterior stage of the insertion process and provides elasticity to the insertion member by supporting the basic edge part of the insertion member. CONSTITUTION:Since the top edge of a tube 26 is supported by a guide 22 in the forestage of an insertion process, the tube 26 possesses rigidity and surely positions a spacer 7 in a gap 6. Further, even if an error exists at the position of a CCD 1 or at the position of the fixed wedge 5 of a prism 2 or further the position of the spacer 7 attracted by an attraction part 27 deflects, a wedge, tapered slender towards the top edge and widened at the gap inlet, to absorb the error. When the spacer 7 is inserted at a certain degree into the gap 6 between the CCD 1 and the fixed wedge 5 of the prism 2, the guide 22 is lowered by a cylinder 20 in the posterior stage of the insertion process, and the tube 26 deeply inserts the spacer 7.

Title: Optical recording card
Inventor: SHINO KUNINORI
IPC: G11B7/00
Filed: 1985-03-01
Abstract: PURPOSE:To improve an error detection/correction function for the information having high importance such as the ID data, etc., by improving the error detection/correction function of the 2nd information recording part higher than that of the 1st information recording part. CONSTITUTION:The data processed with the error detection/correction coding process having the double error correcting function to 4 words among the data of 24 words are recorded to the 1st information recording part 3 consisting of plural information blocks 3A-3N. While the data processed with the error detection/correction coding process having the triple error correcting function to 6 words among 24 words of a track are recorded to the 2nd information recording part 4. Thus the error detection/correction function of the part 4 where the information of high importance like the TOC data, ID data, etc. are recorded is set higher than that of the part 3. As a result, the possibility is improved for correction and restoration of the record contents of the part 4 despite the generation of a burst error, etc. This improves the reliability of an optical record card.

Title: Signal carrying method
Inventor: SATO HIROO
IPC: H04L29/02
Filed: 1986-02-26
Abstract: PURPOSE:To decrease the correspondence time with much noise by applying arithmetic means to a reply signal so as to detect it and using a synchronizing signal as a terminal selection signal so as to inject the signal repetitively. CONSTITUTION:When no replay comes from a terminal equipment, a repeater injects repetitively a synchronizing signal 5 and an address signal 6. When the terminal equipment detects the synchronizing signal 5, the address signal 6 is detected by arithmetic mean and when an address represented by the address signal 6 is coincident with the address of the terminal equipment, at first a reply synchronizing signal 7 is injected. If no reply signal 8 is detected due to noise, the undetectable reply signal 8 is stored and the synchronizing signal 5 is injected again. In receiving the reply signal responding thereto, the previous stored signal 8 and the current replay signal 8 are subjected to arithmetic means to detect the signal. Since the random noise component is decreased by the arithmetic means, the signal detection is facilitated.

Title: Semiconductor storage device
Inventor: ANDO TOMOSHI
IPC: H01L27/108
Filed: 1989-02-20
Abstract: PURPOSE:To improve the degree of integration and software error resistance of a semiconductor storage device by forming an information accumulating electrode in a trench formed in a substrate through an insulating film and a transfer transistor on the electrode. CONSTITUTION:A trench 3 is formed in a substrate 1 of a conductive substance and the inner surface is covered with an insulating film 5. An information accumulating electrode 7 of a conductive substance is formed in the trench 3 covered with the film 5. Then a semiconductive thin film constituting a thin- film transistor 9 which becomes a transfer transistor is formed on the electrode 7 with an insulating film in between and one of the current terminals of the transistor 9 is connected with the electrode 7. The other current terminal and gate terminal of the transistor are respectively connected with a bit line and word line. Therefore, even when the substrate 1 is irradiated with alpha rays and numerous carriers are produced in the substrate, the carriers do not, in principle, enter the electrode 7 and transistor 9 and, at the same time, the area of the substrate can be utilized effectively. Thus the degree of integration and software error resistance of this semiconductor storage device can be improved.

Title: Adjusting unit of fuel injection timing in internal combustion engine
Inventor: UEDA YOSHIYUKI
IPC: F02D1/16
Filed: 1981-03-24
Abstract: PURPOSE:To adjust injection timing in the low speed zone by a method wherein a couple of weights opened widely in accordance with rotation speed of the engine are arranged, and a centrifugal force is acted on the both weights in the low speed zone and on one of the weights in the high speed zone respectively. CONSTITUTION:A rotatory body 30 connected with a fuel injection pump is concentrically arranged on a rotatory body 4 rotating synchronously with the engine. Centrifugal force acting on the weight changes greatly depending on the change of rotation numbers because a weight 31 and a weight 14 are displaced outwards in the radial direction overcoming a spring 22 by centrifugal force is accompany with the rotation of the engine. In the high speed zone a boss 31a of the weight 31 does not change any more by the collision of projections 31a of the weight 31 on the internal periphery of the rotating body 4. Therefore, displacement of a pin 13, i.e. lift is changed only by the centrifugal force of the weight 14. Thus adjustment of fuel injection time is possible even in the low speed zone.
