IPC: G05B19/18
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of improper roundness by reading a compensation value of a tool position per rotation angle of a main spindle corresponding to a selected tool from a roundness compensation data file memory and compensating a position of the tool per rotation angle of the main spindle by the compensation value. SOLUTION: A controller 1 executes a read process of a roundness compensation control program and reads roundness compensation data corresponding to tool number of a tool mounted on a face plate from a roundness compensation data file memory 26 into a RAM 25. Next, the controller 1 executes an operation process of the roundness compensation control program and calculates a tool slider position compensation value which is a tool position compensation value. The tool slider position compensation value is calculated by calculating a compensation coefficient and multiplying the compensation coefficient by a reference compensation value. This compensation coefficient is calculated based on a position of a tool slider and the number of revolution of a main spindle.

Abstract: PURPOSE:To obtain the impurities having an optional density distribution in a semiconductor by a method wherein the surface of the semiconductor is covered by an absorbing material such as metal and the like, an aperture is made and a nuclear reaction is generated by irradiating a radiant ray. CONSTITUTION:The whole exposed surface of the semiconductor substrate 1, made of P type GaAs and the like, is covered by an absorbing material 2 consists of a Gd metal layer by performing a sputtering evaporation, and a pattern of slit-type 3 is made corresponding to the prescribed region. Then the substrate is placed in a nuclear reactor, a radiant ray 4 is irradiated by having a thermal neutron density of approximately 4X10<13> piece/cm<2>-second and the exposed region in the slit 3 of the substrate 1 is converted to an N type layer 5 having a carrier density of 1X10<17>/cm<2>. Thus a layer 5 having a steep carrier density distribution can be obtained without changing too much of the resistance value of the substrate 1. In this constitution, when a more steep density distribution is reguired, the radial ray 4 is formed into a beam-typed radial ray flux using a hollow collimator 6. Also an optional density can be obtained by selecting a desired thermal neutron density.

Abstract: PURPOSE:To reduce the disc friction loss of fluid machines by installing a blowout construction in a low pressure part as against a suction construction, and a suction construction in a high pressure part as against a blowout construction, and installing ducts leading fluid from blowout to suction constructions. CONSTITUTION:Chambers 6a, 6b are formed inside casings 2a, 2b, and communicated with gaps 9a, 9b between an impeller 1 and the casings 2a, 2b through small holes and grooves 8a, 8b opened in surface materials 7a, 7b on inner walls of the casings 2a, 2b. Furthermore, ducts 10a, 10b are communicated from the chambers 6a, 6b to blowout ports 11a upstream of the inlet of the impeller 1. Since the blowout ports 11a have pressure lower than the gaps 9a, 9b, the fluid in the gaps 9a, 9b blows into the chambers 6a, 6b through small holes and grooves 8a, 8b opened in the surface materials 7a, 7b, and blows out to the blowout ports 11a through the ducts 10a, 10b. Suction and blowout are made using a small pressure difference existing in the channel to reduce disc friction of fluid machines.

IPC: E03F5/14
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To improve a sewage shielding plate, maintain its original function and, at the same time, to promote the purification of sewage. SOLUTION: When sewage flows out toward a net-like sewage shielding plate 8 from a sewage inlet 4, part of the sewage flows down from a sewage flowing down passage 9, the sewage other than that passes through the net-like sewage shielding plate 8, and it is lashed against the surface of the sewage accumulated in a sewage storage container. For that purpose, gas or oil content is easily separated from floats on the surface of the sewage. The sewage in the sewage storage container is maintained between the water level Wa around the height H of the sewage inlet 4 and the water level Wc around the bottom wall 2 by functions of both float switches 11a and 11c. The sewage passing through the net-like sewage shielding plate 8 can be contacted to the flat switches 11a, 11b and 11c.  In shower-like sewage, solids contained in the sewage from the sewage inlet 4 are adhered to the inside of the net-like sewage shielding plate 8, and since pressure is weakened by clash it against the net-like sewage shielding plate 8, the malfunction of the float switches 11a, 11b and 11c can be prevented by the shower-like sewage.

Inventor: AKIYAMA MINORU
IPC: G01N15/14
Filed: 1989-06-08
Abstract: PURPOSE:To decrease the signal caused by a stray light component and to improve S/N by overlapping laser light beams having the same wavelength on a rotating wafer, and forming interference fringes. CONSTITUTION:The linearly polarized laser light emitted from a laser light source 1 is split into two luminuous fluxes through a beam splitter 2. Thereafter, the light beams are overlapped on a wafer 6 through mirrors 3 and 4 at an angle theta, and interference fringes having a constant interval are formed. At this time, scattered light whose intensity depends on the grain size is generated when a corpuscle 7 which is attached on the wafer 6 crosses the interference fringes at a velocity V. The electric signal corresponding to the intensity of the scattered light and the electric signal component corresponding to the stray light other than the light caused by the laser light and the scattered light caused by gas on the laser light path are overlapped, and the result is outputted from a photodetector 8. The signal is filtered through a filter 9 so as to pass the frequency component. Thus, the signal corresponding to the scattered light caused by the corpuscle 7 is measured in a processing part 10.
