Filed: 1991-07-26
Abstract: PURPOSE:To obtain the characteristics of a clutch assuming a usual use time by rotationally driving the clutch on one side thereof and connecting the clutch to increase the speed thereof on the other side thereof. CONSTITUTION:A dynamic motor 4 on an input side is connected to a jig head H having a transmission clutch C built therein through a gearbox 6 and a torque meter 8. A motor on an output side is also constituted in the almost same way. A hydraulic type joint-disjoin actuator 50 is constituted of the clutch drum 46 on the input side of the clutch C, the hydraulic chamber 49 thereof and a clutch piston 47 to perform the joint-disjoin operation of the clutch C. The motor 4 holds the clutch C to a predetermined number of rotations on the input side thereof by a CPU and, when the actuator 50 connects the clutch C, the clutch C is increased in speed on the output side thereof along with an inertial body 21. Since the input and output of the clutch C generates a rotational change in the same way at the time of use, centrifugal oil pressure is generated in the actuator 50 in the same way at the time of actual operation. Therefore, the transmission torque at the time of the connection of the clutch can be reproduced in the same way at the time of an on-vehicle state.

Title: Cleaning method using pure water
Inventor: KATSUMATA YUKIO
IPC: H01L21/304
Filed: 1989-07-20
Abstract: PURPOSE:To prevent attachment of particles in air to a body to be cleaned which is lifted up from pure water by discharging the bubbles of carbon dioxide gas from the lower part of the body to be cleaned in the pure water in a container wherein the body to be cleaned is immersed. CONSTITUTION:Bubbles 25 of carbon dioxide gas 24 are discharged at a part lower than an immersed body to be cleaned 1 into pure water 6. The body to be cleaned (semiconductor substrate) 1 is immersed into the pure water 6. Therefore, the carbon dioxide gas is dissolved into the pure water for cleaning the substrate 1, and carbonic acid is formed. The carbonic acid (H2CO3) is decomposed into (+) ions of H and (-) ions of HCO3. Thus, the resistance value of the pure water 6 is decreased. Therefore, static electricity is hard to generate in the substrate 1 in the pure water 6. The negative static electricity of the substrate 1 is offset with the H ions, and the positive static electricity is offset with the HCO3 ions. Therefore, particles in the air are not attached to the substrate which is lifted from the pure water.
