Patent JP-H09199640-A (JP)
Title: Semiconductor package
Inventor: NAKATANI TAKASHI
IPC: H05K3/34
Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To prevent an external lead from being deformed owing to external force by providing a resin protrusion having a length exceeding the tip end of the external lead and having a bottom surface flush with the bottom surface of a package body on a corner part of the package body. SOLUTION: A semiconductor package 10 is adapted such that a resin protrusion 13 formed on a corner part of the semiconductor package 10 has a length exceeding the tip end of an external lead 12 and has a bottom surface flush with the bottom surface of a package body 11. For this, even when external force is applied to the semiconductor package 10, the external force is received by the tip end and bottom surface of a resin protrusion 13, and hence the external lead 12 is prevented from being deformed owing to the external force. Further, since the width of the resin protrusion 13 is small, the amount of use of resin for forming the resin protrusion 13 can be saved. Further, since the resin protrusion 13 comprises an insulating material, a solder bridge, etc., are prevented from being produced between the resin protrusion 13 and the external lead 12.

Abstract: PURPOSE:To attain suitably and automatically correction of a parameter by inserting a value corresponding to a unit delay element of a noncyclic digital filter between an input and a filter whose characteristic is unknown and controlling an adaptive algorithm so as to reduce the 1st variable coefficient to zero. CONSTITUTION:When a delay corresponding to a unit delay element of the noncyclic digital filter is inserted between an input terminal 4 and an unknown filter 2, the 1st variable coefficient C0 of the noncyclic filter is reduced to zero by principles by comparing the noncyclic digital filter 1 and the unknown filter 2 including the unit delay element 6. An offset error of A/D, D/A converters produced when the unknown filter 2 is constituted by the analog system and an error such as round-off produced by digital operations such as addition, subtraction or multiplication are cancelled by utilizing the principles and controlling the adaptive algorithm so as to reduce C0 to zero. The filter 2 having unknown characteristic can be a path detouring voice to a microphone via a speaker or a hybrid circuit coupling a 2/4-wire input and a 4-wire output line.

Title: Obstacle detector of automobile
Inventor: MORIOKA SATOSHI
IPC: G01S7/48
Filed: 1992-01-23
Abstract: PURPOSE:To enable proper detection of an obstacle by providing a control means which detects a propagation loss of a laser beam to substantially increase a laser output per unit area. CONSTITUTION:A signal processing part 11 detects an amount of rainfall or fog via a rain gauge part 9 and a fog detecting part 10. Then beam width, that is a broadening angle, is properly set. When laser beam propagation loss is large, the beam width is narrowed to substantially increase a laser output per unit area. For this purpose, an optic system changing part 12 is activated to operate a light transmitting lens 4 so that the beam width is at a predetermined value. That is, while the beam width is wide in front of an automobile 13 as shown in a region 14 during normal travel, the beam width is reduced as shown in a region 15 when the automobile travels in a fog or rain, resulting in compensation of a drop in detecting capability based on the propagation loss.

Title: Method and device for lapping gear
Inventor: AKIYASU JUN
IPC: B23F19/02
Filed: 1988-01-20
Abstract: PURPOSE:To improve lapping effect by engagingly rotating a pair of gears in the state of no backlash between them to measure the variation of their engaging positions, and determining a fixed engaging position within the range of the above-mentioned variation as a basic engaging position to provide the predetermined backlash between the gears on the basis of the above-fixed engaging position. CONSTITUTION:A pinion gear 10 and a ring gear 12 are engagingly rotated in the state of no backlash between them to measure the variation of an oscillating amount of a pinion head 18, and the backlash is provided on the basis of the average oscillating position of the pinion head 18. Consequently, the backlash averaged on the whole of the gears can be kept nearly constant to reduce the dispersion due to the tolerance of tooth thickness of the backlash per gear, and the backlash to be set in lapping the gear can therefore be made smaller to reduce the occurrence of addendum interference and chattering noise which are caused by tooth bearing at a boundary portion between a lapped and a not lapped part.

Abstract: PURPOSE:To accelerate the processing speed of an optical disk file device by storing the use frequency information of every recording medium, allocating a slot being nearer a recording reproduction part to the recording medium of which use frequency is higher based on the information and replacing the recording medium for each slot. CONSTITUTION:In a floppy disk device 16, a control table 25 controlling the correspondence of each slot 3 and an optical disk 1 in a deck unit 12, that means, the allocation of the slot for the optical disk is housed. Then, by counting the use frequency of the optical disk 1 every time the retrieval executing access for the disk 1 or the registering processing of it, the use frequency of each optical disk is measured are recorded in the table 25. Then, the optical disk of which use frequency is higher is removed to the slot 3 being nearer the recording reproduction part 2. Therefore, the time required for removing the optical disk of which use frequency is high from the slot 3 to the reproduction part 2 or from the reproduction part 2 to the slot 3 can be drastically shortened. Thus, the processing of the optical disk file device can be accelerated.
