Title: Manufacture of semiconductor device
Inventor: OOSHIMA JIROU
IPC: H01L21/22
Filed: 1982-05-31
Abstract: PURPOSE:To obtain a deep Al atom-diffused region without causing Al to be separated out and alloyed, by a method wherein when Al ions are implanted into an Si substrate, Si and Ga ions are simultaneously implanted, and then diffusion thereof is effected. CONSTITUTION:An SiO2 film and an Si3N4 film are laminated on the (111) surface of a mirror-finished Si substrate, and Al, Si and Ga ions are implanted into the substrate. In this case, the accelerating voltage and implantation rate of ions of each impurity are selected so that the concentration distribution peaks of the Al, Si and Ga ions are disposed at substantially the same position in the depthwise direction of the substrate. After the implantation, the Si3N4 film is increased in thickness to prevent any outward diffusion, and diffusion is effected with a temperature raised to 1,200 deg.C at a rate of 20-30 deg.C/hr in order to reduce the stress between the Si and Si3N4 films generated in the early stages of the diffusion and prevent Al from being separated out with a high concentration in the vicinity of the concentration distribution peak. This is maintained at 1,200 deg.C for 60hr. By this constitution, it is possible to prevent Al from being separated out and alloyed, which is impossible when Al is employed solely, and accurately diffuse Al at a high concentration to form a region having a deep junction with an excellent reproducibility.

Title: Cutting chip liquid squeezing device
Inventor: UEDA HAJIME
IPC: B23Q11/00
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To conduct liquid separation from cutting chips in two stages at a high liquid recovery rate by sqeeuzing liquid even while compressed cutting chips are moving up and down in a rising pipe by the reactive force of a pressure device. SOLUTION: Cutting chips 1 which are thrown into a forced compressing chamber 3 from a hopper 5 are compressed in a pressure device 6, and coolant 2 is sqeuezed, and dripped from a slit 10 in a liquid separating means at the bottom of the forced compressing chamber 3 for recovery. The coolant 2 which is compressed in the forced compressing chamber 3 is extruded into an upward taper-type rising pipe 8 by the reactive force of the pressure device 6 for upward movement. By means of the coolant extrusion by the dead weight of the coolant 2 and coolant separation changing with the lapse of time during moving, the coolant 2 is run down and dripped from the slit 10 for recovery.  The cutting chips 1 which reaches a exhaust hole 9 at the upper end of the rising pipe 8 fall naturally from the exhaust hole 9 onto a carriage 11 for recovery with a very small amount of dry cutting chips 1' included in coolant content.

Title: Electromagnetic reciprocal pump
Inventor: KARIYA TOKUJI
IPC: F04B17/04
Filed: 1978-07-29
Abstract: PURPOSE: To provide a reciprocal pump, which does not use mechanical springs but adops an electromagnetic method using an electromagnetic coil and a core for both of the suction and compression strokes so that it is free from time lag at the time of switching of the strokes and can maintain satisfactory operation for a long time.  
     CONSTITUTION: In a state with a suction electromagnetic coil 6 energized and a compression eledctromagnetic coil (not shown) de-energized, by causing attraction of a movable core 5 for suction to cause leftward movement of a piston 9 to the full extent in the suction stroke, the piston 9 can be reliably moved to a required extent with very low electromagnetic force since no resistance is offered to the attraction. In the next compression stroke the regular stroke can be reliably ensured if an electromagnetic force surpassing the back pressure due to the required discharge pressure acting upon the piston 9 is provided. Thus, unlike the prior art no deviation up to a point of balance of spring forces results, so that no time lag is produced at th time of switching of the strokes, thus permitting satisfactory operation to be maintained.

Abstract: PURPOSE:To effectively correct the degradation of color by preliminarily setting the color to be corrected and the corresponding correction amount and performing the color correction selectively in accordance with the color showed by the signal for every input picture element. CONSTITUTION:The picture data VD14 corrected based on the gamma characteristic of a video camera is supplied to a color correction circuit 28. A color decision circuit 28RA generates decision information DR1 based on the data for the upper 3 bits of green color component VDG and blue color component VDB of the VD14. A correction data generation circuit 28RB outputs red correction data DR2 receiving this and the data is added to red color component data VDR in an arithmetic circuit 28RC and the levels of chroma/luminance are increased and corrected. Color decision circuits 28GA, 28BA also perform the similar correction operations. The effective and proper color correction is performed for the respective output picture data VD15 since the data selects the optimum correction characteristic curve for the color component changing in a gamma correction circuit 31 for poststage film.

Abstract: PURPOSE:To avert extending of the time for restraining an operator even in the case of carrying out a continuous treatment of cassette by providing a cassette holding part for sheet housing which can hold the plural cassettes separately from a stacker and cassette holding part for sheet supplying. CONSTITUTION:The stacker 60 is provided between the cassette holding part 10 for sheet supplying and a reading part 20. The cassette 2 loaded in the cassette holding part 10 for sheet supplying is, therefore, capable of taking out an accumulative fluorescent material sheet 1 therein and feeding the sheet to the stacker 60 before reading of the preceding sheet 1 does not end. Loading and taking out of the plural cassettes 2 can be ended in a relatively short time in the cassette holding part 10 for sheet supplying. On the other hand, the sheets 1 subjected to the reading and erasing are successively carried into the plural cassettes 2 in the cassette holding part 40 for sheet housing and, therefore, the operator is simply required to take out the cassette by waiting for the end of the cassette loading. The long-time restraining of the operator is thereby averted.
