Title: Emission spectrochemical analysis of steel
Inventor: SUGIMOTO KAZUMASA
IPC: G01N21/67
Filed: 1990-04-23
Abstract: PURPOSE:To rapidly and exactly analyze the grain size distribution of the inclusions in steel by irradiating a sample with an electron beam to melt a part of the sample and discharging pulses after solidification, then detecting the abnormal value pulses of the emission intensities of spectral rays. CONSTITUTION:The sample 3 is irradiated with the electron beam 2 to melt a part of the sample and to flat the inclusions 5 in the sample on the surface. The inclusions exist more on the surface of a melted and solidified part 4 and the many abnormal value pulses are detected when the pulses are discharged in this part. The detected pulse groups are processed by a regression analysis and the upper tangent G of the pulse groups is determined. The pulses exceeding this upper tangent are decided as the abnormal value pulses and the abnormality degree is determined with every abnormal value pulse. The abnormality values are ranked and the grain size distribution is determined in accordance with the number of the abnormal value pulses belonging to the respective ranks. The grain size distribution is rapidly and exactly analyzed in this way.

Title: Controlling method and device material supply in injection molding machine
Inventor: YAMANAKA YOSHIO
IPC: B29C45/18
Filed: 1991-04-11
Abstract: PURPOSE:To eliminate the need to change setting of manual operation even if the rotational speed of a screw of an injection molding machine changes and also the need for correcting work of manual operation even if overload occurs. CONSTITUTION:A feeder motor drive unit 7 outputs drive current to a feeder motor 4 in response to a given output command. A rotation detector 5 detects the rotational speed of a screw 1. An overcurrent detector 8 detects the drive current outputted from the unit 7. A feeder motor control unit 6 gives an output command which commands an output value of drive current to the unit 7 in response to the detected value of the detector 5. When the detected value of the detector 8 exceeds a set value, the control unit 6 lowers the value of output command so as to stop the motor 4 for a set time period and after the set time period has passed, the unit 6 gradually increases the value of output command and then controls the value of output command again to a value corresponding to the detected value of the detector 5.

Title: Electrostatic chuck equipment
Inventor: KISA TOSHIMASA
IPC: H01L21/683
Filed: 1990-04-20
Abstract: PURPOSE:To prevent deposits of dust due to residual charges while reinforcing attraction strength by forming an insulating film interposed between a predetermined number of electrodes and a semiconductor substrate from an insulator of predetermined specific resistance. CONSTITUTION:An electrostatic chuck equipment 1 incorporates an insulating film 4 formed from an insulator of specific resistance rho(10<8> OMEGAcm<rho<10<12>OMEGAcm) interposed between electrodes 2 and a semiconductor substrate (e.g. silicon wafer) 3. This causes the insulating film 4 to release charges remaining in the semiconductor substrate 3. In other words, the specific resistance rho of this insulating film 4 is a value which enables discharge. Therefore, the semiconductor substrate 3 can be eased of electrostatic deposits of dust. On the other hand, the specific resistance rho of the insulating film 4 is a value which enables control of current flowing through the semiconductor substrate to less than nA: this value reinforces the attraction strength of the semiconductor substrate with the insulating film.
