Title: Check valve
Inventor: UMETSU MITSUO
IPC: F16K15/14
Filed: 1985-05-02
Abstract: PURPOSE:To avoid the trouble of exfoliation of each valve leaf from the inside surface of a tube having softness by integrally forming the valve leaf in thin-film form from rubbery elastic material onto the inner wall of the tube. CONSTITUTION:At a desired position of a tube 1 which is formed to a prescribed length from plastic or rubber which possesses softness, a plurality of petal- shaped or semicircular valve leaves 2 which are shaped into thin-film form from rubbery elastic material are formed continuously each other integrally with the inner wall of the tube 1. With such constitution, the trouble of exfoliation of the valve leaf 2 from the inside surface of the tube 1 is prevented. Further, the stress applied onto each leaf 2 is lightened because of the softness of the tube 1, and durability can be improved.

Title: Blank material and glass optical element and their production
IPC: C03B19/06
Filed: 1992-03-19
Abstract: PURPOSE:To obtain a uniform blank material, having a high dimensional and volume accuracy without carrying out subsequent steps such as grinding or polishing and causing any striae and working deteriorated layer at a low cost by filling interstices between grains with an optical glass material (especially SiO2). CONSTITUTION:An optical glass material powder (e.g. SiO2 amorphous material or crystalline material having >=99.99% purity) having about 2-3mum average particle diameter is press formed or cast molded to form a blank form of a desired shape. In the press forming, a mold made of a metal or rubber is used to perform cold isostatic pressing(CIP). In the cast molding, a protruding part is formed in the outer peripheral part of a cavity in a porous casting mold. A gate is formed so as to face into the protruding part. The resultant formed compact is then sintered using a vacuum furnace or an atmospheric furnace by a hot isostatic pressing(HIP) method (e.g. at about 1400 deg.C in the case of quartz glass). The objective optical element is formed from the resultant blank material by heating the blank material at a temperature higher than the softening temperature by >=30 deg.C.

Title: Carriage travel controller for recorder
Inventor: ARAKI SHIGEYUKI
IPC: H02P8/00
Filed: 1987-04-18
Abstract: PURPOSE:To largely reduce an impact sound at the time of rising by increasing the mean current value at the time of accelerating the rising upon the lapse of a time. CONSTITUTION:Reference voltage generator 8 outputs a predetermined reference voltage in response to an input signal from a pulse generator. This reference voltage is a voltage for increasing a mean current value upon lapse of a time at the time of accelerating rising. A comparator 9 detects a voltage corresponding to a current value by detecting the current value flowing to the phase of a stepping motor with a reference voltage. A pulse driver 3 is driven by the output of the comparator 9. Thus, a torque in the motor at the time of rising is initially low and increased upon the increase of its frequency to be abruptly accelerated.

Title: Method for removing technetium in waste liquid
Inventor: USUI KAZUYA
IPC: G21F9/12
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To make it possible to safely execute a radioactive waste treatment by bringing the technetium(TC) in a waste liquid into contact with the particles of the specific grain size of a strong basic anion exchange resin having trimethyl benzyl ammonium salt as an exchange group and having a specific moisture content. SOLUTION: The TC(TcO4 <-> ) in the waste liquid is brought into contact with the particles of the grain size of <=0.3mm of the strong basic anion exchange resin having the trimethyl benzyl ammonium salt as the exchange group and having the moisture content of 43 to 48% to adsorb away TcO4 <-> by an ion exchange. The representative example of the strong basic anion exchange resin of the moisture content of 43 to 48% is of about 8% in the degree of crosslinking expressed by a divinyl benzene content. The contact of the waste liquid with the exchange rein is executed by passing the waste liquid in a column packed with the exchange resin particles at an empty tower velocity of about; 3 to 5hr<-1> .  A strong acid is acted on the exchange resin adsorbed with TcO4 <-> in succession to this contact, by which the eluted TcO4 <-> is reduced and is precipitated in the form of TcO2 to separate the TcO4 <-> . The stage of a solidification is thus executed.
