Title: Connector for board
Inventor: OKAMOTO MASAKI
IPC: H01R12/71
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To keep such a state that a terminal fitting does not project to the outside of a connector housing. SOLUTION: When a connector housing 11 is not fixed to a circuit board, a stress relaxation part 22 of a terminal fitting 20 is elastically bent, the tip of a board fixing part 23 is bumped against a bending restricting piece 15, and the board fixing part 23 is held in a drawing back position where it does not project from the connector housing 11. In this state, the board fixing part 23 is not interfered by other members in storage or transportation. When the connector housing 11 is fixed to the circuit board, a releasing contact part 15B comes in contact with the circuit board, the bending restricting piece 15 is elastically bent from the restricting position to the releasing position, the board fixing part 23 is released from the drawing back position, and inserted into a through hole.

Title: Optical disk reproducing device
Inventor: UCHIDA SHIGERU
IPC: G11B7/00
Filed: 1988-10-20
Abstract: PURPOSE:To shorten the waiting time until the data are reproduced by providing a high speed mode to read out data of an index part, data for track access time and the data to be reproduced. CONSTITUTION:In order to speed up the read-out speed for the data of the index part, the data for the track access time and the data to be reproduced, an oscillation frequency of a reference clock generating device 11 is set, for instance, as a frequency of a 2nd reference clock to be oscillated in such a frequency as exceeding an oscillation frequency of a 1st reference clock. Then, the 2nd reference clock is given to a signal processing device 5 by a dividing ratio changeover device 12 according to a command of a microcomputer 10 because of no dividing for the high speed mode, while the 1st reference clock is given to the signal processing device 5 for the normal mode because of dividing of 1/2 frequency demultiplication. By this method, the waiting time until the data are reproduced can thus be shortened.

Title: Rolling formation of flat tube and device therefor
Inventor: KOBAYASHI KAME
IPC: B21D53/06
Filed: 1996-09-16
Abstract: PROBLEM TO BE SOLVED: To enable the rolling formation of a flat tube in high precision and at high speed by forming a truncated projecting part formed at the center part of a band sheet to a folded projecting part and the bending part to both ends in the width direction of the band sheet, bending this bending part so as to closely contact with both sides of the folded projecting part and making the large curvature and the small recessed part to the folded projecting part in a reinforcing part. SOLUTION: In a first process and a second process, the truncated projecting part 416 is formed at the center part in the width direction of the band sheet, and the width L1 at the upper side is gradually narrowed, and after forming almost triangular shaped projecting part 426, the insides of projected two sides are brought into close contact with mutually the other parts and folded to form the projecting parts 43, 44. In this result, since the curvature radius at the bending part in the truncated shape becomes large, bending stress becomes small and also, the range working the stress is dispersed, and since the width L1 of the upper side in narrowed and the bending position is shifted the tension stress is not concentrated.  By this method, the bending part in the projecting part is not contracted and not thinned, and the rolling formation can be executed in the high precision and in the high speed.

Abstract: PURPOSE:To facilitate the arrangement of sheets after copying by copying documents which are divided by item classifying sheets for each division detected by a detecting means, and distributing and accumulating said sheets on vacant bin trays detected by a vacant bin tray detecting means. CONSTITUTION:Documents of plural items are set on a loading sheet-type document feeding/discharging device part X and item dividing sheets are set on the head of the documents. Then, as a copying device body is turned on, one sheet on the bottom part of the documents is fed and stopped at an exposure part 9. And, whether the document on the exposure part 9 is a document to be copied or an item classifying sheet is judged by an item classifying sheet detecting means 7 and, when the document is an item classifying sheet, it is returned to the feeding/discharging device part X by means of document discharge means 10 without being copied. On the other hand, when it is a document to be copied, a group of documents which are divided by the item classifying sheets are copied by a defined number of sheets. Then, in a sorter part Z, a vacant bin tray is detected by a vacant bin tray detecting means and the group of copied sheets are accumulated on a designated vacant bin tray by sheet distributing/accumulating means 55-62.

Title: High breakdown strength diode and its manufacture
Inventor: YANAGAWA HIROSHI
IPC: H01L27/06
Filed: 1994-10-31
Abstract: PURPOSE: To provide a high breakdown strength diode which facilitates breakdown voltage design and shows low operating resistance after yielding. CONSTITUTION: An N-region 12 is formed for a cathode on a P-type semiconductor substrate 11, and a P-region 15 whose potential is identical to that of the semiconductor substrate 11 is added to its surface. Thereby, when a reverse voltage is applied across an anode electrode (A) and a cathode electrode (K), a depletion layer is expanded into the N-region 12 from the P-N junction part of the N-region 12 to the semiconductor substrate 11. In addition, since the P-region 15 is at the same potential as the semiconductor substrate 11, a depletion layer is expanded into the N-region 12 also from the P-N junction part of the P-region 15 to the N-region 12. Thereby, both depletion layers are connected.  In addition, when a higher voltage is applied, a prescribed breakdown voltage is decided by the length of the P-region 15 because the two depletion layers are brought into contact (pinched off). As a result, the breakdown voltage is not influenced by the impurity concentration of the N-region 12. In addition, since the two depletion layers are expanded, the impurity concentration of the N-region 12 can be made large and its depth can be made deep within a range in which they are pinched off. As a result, an operating resistance can be reduced after a high- breakdown-strength diode has been broken down.

Title: Wiring structure of semiconductor integrated circuit
Inventor: MIZUSHIMA KAZUYUKI
IPC: H01L23/522
Filed: 1988-10-22
Abstract: PURPOSE:To reduce a capacitance generating between a wiring and a semiconductor substrate without increasing the thickness of an oxide film by constituting a part of the oxide film for element isolation by using a thick insulating film, and forming a part of wiring on the insulating film. CONSTITUTION:A part of an oxide film 13 for element isolation formed on a semiconductor substrate 11 is constituted by using a thick insulating film 14, and at least a part of a wiring 16 formed on the oxide film 13 is formed on the insulating film 14. That is, it is not necessary for all wiring to be formed on the thick insulating film 14, and only the wiring whose parasitic capacitance becomes a serious problem is formed thereon. By this set-up, the capacitance between the semiconductor substrate 11, the first wiring 16 and a second wiring 18 scarcely changes, when the thickness of the oxide film between the semiconductor substrate and the wiring is changed. Only the capacitance of large value between the first wiring and the semiconductor substrate decreases remarkably, so that the parasitic capacitance can be reduced without reducing the surface area of the first wiring 16. Thereby, a thick insulating film can be formed without affecting miniaturization, and the reduction of parasitic capacitance is enabled.
