Title: Method for pressurizing in pressure crystallizer
Inventor: ASARI AKIRA
IPC: B01D9/02
Filed: 1986-03-11
Abstract: PURPOSE:To increase the life of a filter and to improve the purity of a crystallized body by pressurizing a pressure vessel by a plunger while moving the vessel which is floated after pressure crystallization or from the latter half of pressure separation to the lid body side. CONSTITUTION:The lock of a backup cylinder 13 is released after pressure crystallization or when separation proceeds to some extent, hence the pressure vessel 1 is floated, the pressure vessel 1 is pushed down by an elevating cylinder 3, and the lower lid body 7 is relatively pushed into the pressure vessel 1. Consequently, vertically uniform pressure is exerted on the filter 4. Accordingly, the shearing force exerted on the filter 4 is not excessive, the life of the filter 4 can be increased, the pressure can be surely increased to the lower zone, and the deterioration in purity due to the insufficient compression of the lower crystallization can be prevented.

Title: Treating tool for endoscope
Inventor: OUCHI TERUO
IPC: A61B17/28
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To surely recognize a position for interrupting the inserting/detaching operation of a treating tool by providing a member for generating resistance to the inserting/detaching operation by being abutted to the hand side insertion port part of a forceps channel on the outer surface of a sheath. SOLUTION: To the sheath 101, an inserting/detaching resistance generation member 105 formed in a short cylindrical shape from a rubber or plastic material or the like with elasticity is mounted to the position of a prescribed distance B from a tip and an index 100 is formed on the surface. Since an inner diameter dimension is formed slightly narrower than the outer dimension of the sheath 101, the member 105 is locked to the surface of the sheath 101 in the state of lightly tightening the sheath 101 from an outer side by its own elasticity.  Thus, since frictional resistance is generated between the sheath 101 at the time of movement, when this treating tool 100 is inserted to the forceps channel of an endoscope 10 and the member 105 is abutted to a forceps plug, the frictional resistance by the movement is generated from the point of time and it is turned to the increase of inserting resistance, detected by the hand of an operator and recognized.

Title: Method of controlling temperature of furnace for evaporating solid sample
Inventor: USAMI YASUTSUGU
IPC: H01J27/02
Filed: 1985-03-20
Abstract: PURPOSE:To accurately control the temperature of a furnace for evaporating a solid sample used as an ion source for an ion implantation device or a similar device while avoiding use of a thermocouple so as to prevent misoperation by determining the temperature of the furnace from the resistance of the heater. CONSTITUTION:A furnace for evaporating a solid sample used as an ion source for an ion implantation device or a similar device is constituted of a sample reservoir 1 and a heater 2 for heating the reservoir 1. Electric power is supplied from a power supply 3 to a heater 2 and changes in the resistance of the heater 2 resulting from its temperature changes are input to an isolation amplifier 4. A comparator 6 is used to compare the output of the amplifier 4 with that of a setter 5 to generate an error signal which is then fed back to the power supply 3 thereby controlling the supply of electric power to the heater 2. Therefore, it is possible to prevent any temperature error or misoperation which might result from changes in the state of the heater 2 attached to the reservoir 1 by avoiding use of a thermocouple. Furthermore, it is possible to reduce the size of the device and to simplify its structure.

Title: Brake shoe
Inventor: KOTANI YOSHIO
IPC: F16D65/02
Filed: 1982-03-31
Abstract: PURPOSE:To reduce the weight of a bake shoe by integrating a fitting portion for some other parts with the frictional portion of the brake shoe, by using a molding material containing a metallic filler. CONSTITUTION:A brake shoe is obtained by integrating a fitting portion 12 for some other parts with a frictional portion 11 by using a molding material containing a metallic filler. The frictional portion 11 corresponds to a conventional frictional material 1 and the fitting portion 12 corresponds to a metal fitting 2. In the fitting portion 12, since an extremely large stress is applied to a threaded hole into which a thread 21 is inserted, a metallic insert 13 or a steel wire is buried in the periphery of such a portion for the purpose of reinforcement. By integrating the fitting portion with the frictional portion, a metal fitting can be replaced with a synthetic resin molded article. Therefore, the weight of the brake shoe can be reduced and the process of sticking the frictional material to the metal fitting can be obviated.
