Title: Method and apparatus for production of metal powder
Inventor: ICHIDATE MINORU
IPC: B22F9/08
Filed: 1978-12-19
Abstract: PURPOSE: To produce the metal powder which does not contain any oxide, is of irregular shape  and is suited for raw material for sintered moldings and powder forgings by disintegrating molten  metal in a non-oxidative atmosphere by an atmosphere by an atomization method using non-polar solvent and further subjecting the same to softening heat treatment.   
     CONSTITUTION: Molten metal 2 in a vessel 1 which is cut off from the atmosphere and is put in  a non-oxidative atmosphere is atomized into an atomization cell 5 from a nozzle 4 with non-polar  solvents such as kerosene and benzene or mineral oils and vegetable oils as an atomization medium. The inside of the atomization cell 5 is of course a non-oxidative atmosphere, in which the  molten metal 2 is quenched by the atomization medium to become fine powder of irregular shapes. After the fine powder accumulates in the lower part of the cell 5, it is put in a hopper 18 by a  classifier 7. The atomization medium having accumulated in the cell 5 is removed of solids by  way of a thickener 8 and filter 12 and is cooled in a cooler 10, after which it is recirculated for  atomization. The metal powder next enters a fluidized bed furnace 24, where the deposited  atomization medium is evaporated by the high temperature gas generated by a heater 26 in the  layers of the upper two stages, after which the quench-hardened mateial is softened by heating  with a heater 26, whereby it is made easier for use as sintering raw material, etc.

Abstract: PURPOSE:To obtain a color sensor capable of discriminating colors correctly, by piling up three or more PIN or PN junction layers on a substrate and forming electrodes on the top and the bottom of each layer such that both the electrodes have light transmission properties or such that one of them has light transmission properties while the other has non-transmitting properties. CONSTITUTION:Incident light 1 first passes through a first layer consisting of a P-type semiconductor 4a, an I-type semiconductor 5a and an N-type semiconductor 6a, where short-wavelength components of the incident light 1 are absorbed by the PIN junction of the first layer. The residual light which has not been absorbed by the first layer passes through a second layer consisting of a P-type semiconductor 4b, an I-type semiconductor 5b and an N-type semiconductor 6b, where intermediatewavelength components of the incident light 1 are absorbed by the PIN junction of the second layer. Further, the residual light which has not been absorbed either by the second layer passes through a third layer consisting of a P-type semiconductor 4c, an I-type semiconductor 5c and an N-type semiconductor 6c, where long-wavelength components of the incident light 1 are absorbed by the PIN junction of the third layer. The light components absorbed by the respective layers are converted photoelectrically by the PIN junctions and taken out as photocurrent. Since the upper layer serves as a color filter of the lower layers, there is no need of providing an external color filter.

Title: Antilock brake controller of vehicle
Inventor: ISHIKAWA TERUYASU
IPC: B60T8/32
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To improve the follow-up property of brake pressure control by constituting a PID operation means in such a manner that a PID operation value is restricted in a predetermined limit value. SOLUTION: When a PID operation value Kpid is restricted in a predetermined limit value, the inversion of the PID operation value Kpid is speeded, the tim Tout of pressure reduction mode is made short comparatively, the time Tin of pressure increase mode is made short, and the start of pressure increase mode is advanced. Consequently, a difference between an estimated wheel slip condition and an actual wheel slip condition is made small comparatively, even if the PID operation value Kpid becomes excessive due to the generation of noise around an arithmetic unit. Consequently, it is possible to avoid delay in brake pressure control and improve the follow-up property of control, even if an abrupt change occurs in a wheel slip condition due to the change of friction coefficient of a road surface.

Abstract: PURPOSE:To stably control the depth of defect-free region which will become an element forming region by executing first the intrinsic gettering(IG) process and then executing extrinsic gettering(EG) process for a silicon single crystalline wafer formed by the Czochralski method. CONSTITUTION:A defect-free region 2 is formed in an element forming region of the surface 1a of a silicon single crystalline wafer and a defective region 3 of oxygen precipitated substance in a wafer 1 by the IG processing to the silicon single crystalline wafer 1. Practically, oxygen in an element forming region provided between the surface 1a of wafer 1 and a region near the surface 1a is removed through the external diffusion by executing high temperature heat treatment at 1100 deg.C for three hours for the silicon single crystalline wafer 1 in order to form integrating oxygen only within the wafer 1. Next, the wafer 1 is subjected to low temperature heat treatment at 650 deg.C to form oxygen precipitated core within the wafer 1. Moreover, the oxygen precipitated core in the wafer 1 is grown to oxygen precipitated substance in order to form a defective region 3 through the high temperature heat treatment at 1000 deg.C. A silicon single crystalline wafer 1 can be obtained by forming a defective region 4 at the rear surface 1b of the wafer 1 with the EG process to the wafer 1 by the polysilicon coating method.
