IPC: H01L21/301
Filed: 1986-12-16
Abstract: PURPOSE:To prevent any edge short-circuit from occurring even if any chip edge corners of metallic fine wires come into contact with one another by a method wherein, within a dicing region adjacent to bonding terminals, impurity partial diffused regions forming a PNP junction are formed. CONSTITUTION:Bonding terminals 12 connected to an element by inner wirings 13 are provided on the peripheral surface of a chip 10 while one ends of Al fine wires are connected to the terminals 12 and the other ends are connected to inner ends of lead terminals of an outer container. The bonding terminals 12 are provided on a field oxide film 4; a dicing region 11 of a part of thin oxide film 5 following the chip edge of film 4 is formed into an N type epitaxial layer 2 formed on a P type substrate 1; and P type partial diffused layers 3 are formed in the layer 2. In such an IC, even if the fine wires 14 connected to the terminals 12 come into contact with a part of substrate slightly exposed from the films 5 in case of cutting chip 10 at the chip edge corners, any edge short-circuit can be prevented from occurring even if terminals come into contact with any chip corners due to the layers 3 existing in the layer 2 as well as the PNP junction laid between the terminal 12.

Title: Manufacture of angle material
Inventor: FURUTA OSAMU
IPC: B21D5/08
Filed: 1989-11-20
Abstract: PURPOSE:To make the interior material in contact with the inside surface of the angle material without clearance by bending the metal plane material in nearly right angle, rolling the inner angle corner while heating and bringing the inside wall of circular arc type recessing relief part of the inner angle part to the inner side of the intersection of the extension lines of each inside surface. CONSTITUTION:The manufactured angle material 1 has the circular arc type recessing relief corner 103 at the inner angle part 102 and the inside wall of recessing relief corner 103 is positioned at the inner side of the virtual intersection of the extension line of each inside surface of both the side parts 11, 12. Therefore, the inner angle part 102 of the angle material 1 is brought in contact with the outer angle part of right angle 81 of the interior material 8, and both 1, 8 can be brought into contact with each other closely. At this time, because the outer angle part of right angle 81 of the interior material 8 is entered in the inside of the recessing relief corner 103 which is formed at the inner angle part 102 of the angle material 1, the clearance between the interior material 8 and the angle material 1 is not generated. Further, when the inner angle part 102 is worked with finishing in circular arc type, the working for the inner angle part 102 is easily executed, because it is worked with rolling while locally heating.

Title: Optical information recording and reproducing device
Inventor: WATANABE MASAHIKO
IPC: G11B7/095
Filed: 1989-11-22
Abstract: PURPOSE:To prevent an information processing time from being extended unnecessarily owing to an external noise or flaw by providing an eccentricity quantity detecting means, a detection output memory, and an error detecting means and carrying on memory operation when an error output is less than a reference value. CONSTITUTION:A motor 8 rotates a disk 1 and a light beam controller 9 on a rear surface side irradiates the disk with a light beam 10 and deflects the beam radially. A beam position detecting device 11 measures the quantity of displacement of the beam. The quantity of displacement is inputted to the eccentricity quantity detecting means 12, which measures the quantity of eccentricity between the center of rotation of the disk and the center of a track and stores a memory 13 with rotation information on the motor 8 relatively. Position information on the current point of the beam 10 and the information in the memory 13 are added 15 and the result is inputted to a compensation controller 16. The controller 9 deflects the beam according to the input information of the compensation controller. A CPU 17 controls the memory 13 and applies a control signal to an addition point 15 at need to control the compensation controller 16. Consequently, when a irradiation deviation is temporary, the releading-in operation for the track is omitted and the efficiency of a series of operation is improved.

Title: Method for recovering salts from waste water
Inventor: CHIYAN SHI CHIYAN
IPC: C02F1/30
Filed: 1991-11-18
Abstract: PURPOSE: To reduce energy and a cost and to improve the purity of recovered salts by radiating the sodium chloride in waste water with IR rays to accelerate the covering of its surface with org. compd. layers and subjecting the waste water to evaporation and decomposition reaction at a high temp., thereby removing miscellaneous materials and purifying the salts.  
     CONSTITUTION: This method for recovering the salts from the waste water consists in irradiating the sodium chloride in waste water with the IR rays to accelerate the covering of its surface with the org. compd. layers. The org. miscellaneous materials absorb the IR rays and, therefore, the temp. rises and the evaporation and decomposition reaction occur at the high temp. The miscellaneous materials are then removed to purify the salts. In the meantime, the driving force of the radiation is the four- dimensional difference of the absolute temp. and the salts themselves are extremely large in the temp. difference after the org. compd. layers are radiated with the IR rays and, therefore, the temps. of the salts and org. compd. layers subjected with the irradiation with the IR rays rise and the control thereof to the high temp. is possible. The pyrolysis is further rapidly and completely progressed and simultaneously the salts are not separately fused and, therefore, the pyrolysis yields the better recovered salts.

Abstract: PURPOSE:To easily find out the end of a part recorded with an MUSE signal and to consecutively perform additional recording. CONSTITUTION:Upon completion of recording the MUSE signal, an END signal is recorded in a 564th line of the last frame. At the time of an additional recording mode, a magnetic tape 5 is reproduced at high speed, and when a reproduced signal is not detected by a reproduced signal detecting circuit 9, the tape is rewound for a given period of time, and afterward, the normal reproducing is performed. The END signal of the last frame is detected by an END signal detecting circuit 10 so that a control signal is sent to a mechanism control circuit 11, and hence the recording mode is effected after slightly rewinding the magnetic tape 5.
