Abstract: PURPOSE:To measure the concn. of the soybean milk in which a bean cake right after grinding is made to coexist by forcibly passing a part of the soybean milk flowing down in a receiving tank into the spacing between the measuring surface of a concn. meter and the irradiating surface of a light projector. CONSTITUTION:The receiving tank 3 is disposed in the position below an outlet 2 of a grinding mill 1. The soybean milk contg. bean-curd refuse delivered from the outlet 2 is forced down onto the base of the receiving tank from the central part thereof by a screw 13 provided in the upper part in the receiving tank 3 and thereafter, the soybean milk flows upward along the inner side faces of the receiving tank and flows out of the outer peripheral edge at the top end of the receiving tank. The stagnation of the bean-curd refuse in the receiving tank 3 is prevented in this way. The measuring surface 5 of the optical concn. meter 4 and the irradiating surface 7 of the light projector 6 are oppositely equipped in the receiving tank 3 and a spacing is formed between the two surfaces. A part of the soybean milk contg. the bean-curd refuse is forced to flow down in this spacing by the screw 13. Light is projected from the light projector 6 and the concn. of the soybean milk is measured at the measuring surface 5. The measuring surface 5 is cleaned at all times by the flowing down bean- curd refuse (solid) so as to be ready for measurement. The light quantity and intensity for measurement are variably adjustable.

Abstract: PURPOSE: To provide a lock release mechanism which is prevented from the forced return of a sleeve due to release of a lock by releasing a lock through movement of a leaf spring disposed at a casing so that during mounting, a lock by a locking means is slidable integrally with a support body. CONSTITUTION: When a chain tensioner 10 is mounted, for example, a fastening tool, such as a bolt, is screwed in a fastening hole 16 and fastened against a support body 11. In which case, a distance between the chain tensioner 10 and the support body 11 is decreased and a hook 41, i.e., a leaf spring 31, is started to move to the left along a casing 12. In such a way that a pin upper end part 35 is moved over a protrusion 43 and a pin 36 is pushed up, a plunger 24 is slidable within a cylinder 26. When in the lock release state, an engine is started, a given oil pressure is fed in a cavity 48 through an oil pressure feed passage 57, an oil pressure feed passage 56, and an oil passage 58. As a result, a check ball 30 is separated away from a cavity 48 and the oil pressure of the cylinder 26 is rapidly increased and finally a lever 20 is pressed against a chain.

Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a bubble generator, in which, even if the actual suction head is changed, very fine bubbles can be stably generated in a storing tank. SOLUTION: The discharge pressure of a pump 15 is detected, and the drive of an intake quantity adjusting valve 19 for adjusting the opening of an air suction pipe 16 is controlled by a controller 28 in such a manner that the discharged pressure becomes a preset reference discharge pressure. Thus, even if the water level (actual suction head) is changed during bathing, the generating condition of very fine bubbles can be kept constant. Furthermore, as the drive of the intake quantity adjusting valve 19 is controlled according to the discharge pressure of the pump 15 by the controller 28, even if the fitting position of the pump 15 and the length and thickness of the water suction pipe 14 are varied, the generating condition of very fine bubbles can be kept constant.

Abstract: PURPOSE:To easily maintain the capacity of a sucked liquid sample and to improve the work efficiency by providing a pressure adjusting means for adjusting the internal pressure of a pipet main body so as to maintain the capacity of the sample sucked into the pipet main body which motions in linkage with a manipulator. CONSTITUTION:The water pressure applied on the tip of a pipet main body 14 is reduced in accordance with the pipet main body 14 ascending in a liquid sample. The liquid sample sucked into the pipet main body 14 intends to flow out of the pipet main body 14, by the pressure change like this. In this case, a piston 25 is lifted inside a cylinder 22 with a pressure adjusting means 21 being actuated in linkage with the manipulator for moving the pipet main body 14 and the internal pressure of the pipet main body 14 being adjusted, so no flowing out of the liquid sample is caused. Namely, the internal pressure of the pipet main body 14 is reduced by the pressure adjusting means 21, the internal pressure of the pipet main body 14 and the water pressure applied at the pipet main body 14 tip while under moving are balanced, and the flowing out of the liquid sample from the pipet main body 14 is prevented.
