Title: Wafer polishing device
Inventor: HAMAGUCHI TSUNEO
IPC: B24B37/005
Filed: 1985-08-14
Abstract: PURPOSE:To enable the manufacture of a flat surface wafer without any distortion by providing a means wherein the larger a clearance is between the wafer and a polishing plate in a direction off the polishing plate, the smaller a force tends to be on a support plate. CONSTITUTION:With a clearance 8 formed between a wafer 1 dipped in a grinding liquid 11 and a polishing plate 7, the wafer 1 and the polishing plate 7 are made to have relative motion. Then, the polishing liquid 11 starts to flow at the clearance 8 between the wafer 1 and the polishing plate 7 and the more said relative motion is, the less the pressure is at the clearance 8. Consequently, a wafer supporting plate 2 held by grinders 5 and 6 are attracted toward the polishing plate 7 to such an extent that the clearances 8 becomes fine. In this case, a concave 10 formed on the polishing plate 7 works to help lowering the pressure by making an eddy in the fluid current. When grains contained in the polishing liquid 11 passes the clearance 8 at a high speed, they chafe, process in an atomic order accuracy and polish without any distortion, the wafer 1 respectively.

Title: Body cavity internal pressure control apparatus for endoscope
Inventor: HONDA RYOJI
IPC: A61B1/00
Filed: 1987-07-17
Abstract: PURPOSE:To automatically remove mucus, by increasing the sucking amount of a suction means by the output signal from a comparing means when the internal pressure of a suction pipeline after sucking operation is lowered by the accumulation of the mucus in the bent part of the suction pipeline. CONSTITUTION:When mucus is accumulated in the downwardly bent part of a suction tube 14 and not extracted by one sucking (vacuum) operation, a pressure detector 16 detects atmospheric pressure or pressure equal to or less than said pressure immediately after sucking operation is finished. The sucking operation is repeated by the rising in the pressure in the tube by the feeding of air from the second air feed means 17 and, when atmospheric pressure or pressure equal to or less than said pressure is continuously detected by the pressure detector 16 during a time when said sucking operation is repeated three times, the sucking operation is continuously performed for a long time by the output signal from the input/output interface 25a of a microcomputer 25 and clogged mucus is sucked and discharged. Therefore, the automatic control function of the internal pressure of the body cavity can be always kept.

Abstract: PURPOSE:To make simple and precise measurement of hardness possible with a surface roughness left in an original state, by making a presser scratch a sample while applying two kinds of measuring loads thereto and by detecting a difference in the intrusion depth of the presser. CONSTITUTION:When a slide piece 13 is moved in the direction of an arrow B, a pin 12 projects downward from a support frame 2, pierces through a hole 3c of a spring 3 and presses a spring 4 downward. Thereby the right end part of the spring 4 is detached from a projection 3b of the spring 3, the spring force of a loading spring is lowered thereby and a pressing load of a presser 9 on a sample is reduced. While two kinds of loads are applied to the presser 9 alternately at appropriate intervals by moving the slide piece 13 in the direction of the arrow B and the opposite direction and by subjecting electrification of an electromagnetic coil 3a to an ON/OFF control, the frame 2 is moved in the direction of arrow A and made to execute a scratching motion and the intrusion depth of the presser 9 into the sample 10 is detected. In an analyzing part, a difference in the intrusion depth of the presser 9 under the condition of the two kinds of the measuring loads is computed and the hardness of the sample is calculated on the basis of the computation.

Title: Film thickness monitoring method
Inventor: KOZUKA MICHI
IPC: H01L21/66
Filed: 1985-08-16
Abstract: PURPOSE:To enable a non-destructive inspection by coating a film with a pattern having a step of a monitoring pattern, then observing by an optical microscope from above a substrate, and measuring the film thickness coated on the side of the step as a plane size in the microscope visual field. CONSTITUTION:The ratio of the thickness of a film coated on a plane surface to that of a film coated on the side of a step always becomes constant if physical conditions at coating time such as a material of the film, a coating principle and the type of a coating machine are secured. When observing from above the film thickness monitoring pattern after film coating, the width of the monitoring pattern is observed to be increased due to the film coating on the side of the step. Thus, if the end W1 of the monitoring pattern is obtained in advance, the width of the monitoring pattern after film coating is observed by the microscope to monitor the film thickness coated on the plane surface.

Abstract: PROBLEM TO BE SOLVED: To increase charging current and prevent the exhaustion of a battery by fitting a specific gravity sensor to the battery, and increasing the idle engine speed, when a control device detects a specific gravity abnormality with the signal from the specific gravity sensor. SOLUTION: Whether or not a mode selection switch manually selected by a driver is set to a normal mode selected at the time of a normal travel is judged. If the decision is YES, i.e., a normal mode, the signal of a specific gravity sensor is read, and whether or not the specific gravity value is a prescribed value or below is judged. If the decision is NO, the signal of the specific gravity sensor is read again. If the decision is YES, since it means an insufficient charge, a solenoid valve is turned on, and the idle engine speed is increased so as to increase the charging current. If the specific gravity value has not reached the prescribed upper limit value after the charging, a battery is judged to be dead, a battery replace warning is turned on to blink a warning lamp, and the control is finished.
