Patent JP-S60804-A (JP)
Title: Ultrafiltration apparatus
Inventor: INOUE AKITO
IPC: B01D65/08
Filed: 1983-06-20
Abstract: PURPOSE:To remove simply the clogging of the membrane arising in the process of filtration by exerting the pressure to the filtrate side, and changing over alternately the flow of the original liquid to the opposite direction in an ultrafiltration apparatus. CONSTITUTION:An original liquid 11 stored in an original liquid tank 10 is circulated and supplied into an ultrafiltration apparatus 13 at specified pressure by the action of a pump 12 through flow rate control valves 16 and 17 and a direction changeover valve 30. The valve 30, consisting of a four-way valve, has the function to allow the original liquid 11, which is sent from the pump 12 through the flow rate control valve 16, to pass through the ultrafiltration apparatus 13 from the left to the right or conversely from the right to the left, and can be changed over alternately at intervals of a specified time to the opposite direction by the control of a control circuit provided outside or manually. In this way, the clogging while filtering can be prevented only by changing over the flowing direction of the original liquid.

Title: Level shift circuit
Inventor: MASUDA NOBORU
IPC: H03K19/00
Filed: 1986-05-16
Abstract: PURPOSE:To compensate the change in the circuit characteristic due to temperature change without using a control signal by adding a source follower circuit whose level shift quantity is increased as temperature rises to a diode in a level shift circuit for a semiconductor integrated circuit. CONSTITUTION:Gate and source of elements whose current is increased as temperature rises, e.g., normally-on type FETs 1, 2 having not so much threshold voltage are connected in common in the source follower circuit and the components are used as a load. The level shift of the source follower circuit is selected as nearly -1 time of the threshold voltage of the FETs 1, 2 so that the change in the level shift of the source follower circuit and the change in the forward voltage drop of the diode are just cancelled. That is, gate widths W1, W2 of the FETs 1, 2 are designed to be W2=4W1. As a result the temperature change of Vf, Vt is cancelled together and a voltage difference Vi-Vo between an input terminal 100 and an output terminal 101 is made nearly constant independently of the temperature.

Title: Correcting method for heat displacement of machine tool having resin concrete-made structural material
Inventor: TSUTAI KAZUO
IPC: B23Q15/18
Filed: 1992-04-02
Abstract: PURPOSE:To provide stabe working dimension having low change with the lapse of time in work hours by correcting heat replacement generated by the difference between the heat conductivity of resin concrete and that of a metal. CONSTITUTION:A position detecting sensor 15 is mounted on the tip of a metal- made rod 14 in which its base end is fixed to a resin concrete-made bed 1 through a spacer 13. A detecting piece 11 is fixed to the bed 1 in the area ahead of that for having the position detecting sensor 15 sensed. When the resin concrete is the same as the metal in coefft. of thermal expansion to temp. change, no change is observed in the value of the detecting piece 11 sensed by the position detecting sensor 15 mounted on the tip of the metal-made rod 14: however, both the materials have different coefft. of thermal expansion, displacing the detecting value of the position detecting sensor 15 with the lapse of time. Therefore, the displacing amount is fed back to the position controlling system of a slide to correct slide moving amount, preventing a change in dimension caused by the heat displacement of both the materials.

Title: Tritium monitoring system
Inventor: TOMOTA TOSHIMASA
IPC: G01T1/167
Filed: 1985-05-23
Abstract: PURPOSE:To enable a correct measurement down to a low level to be performed even after a leakage accident by measuring a tritium density by using a second tritium monitor which is not contaminated by the leakage accident when the leakage accident is being repaired or presumed to be repaired. CONSTITUTION:A second tritium monitor 11 and a tritium monitor 7a which is one of first tritium monitors are provided in parallel. Normally and when a tritium leakage accident occurs, valves 12a and 12b are closed to prevent the invasion of the air containing tritium of a high density into the second tritium monitor 11 and therefore this is not contaminated by tritium. At the time when the leakage accident has been repaired and the tritium density is decreased by some degree, when the accident is presumed to be repaired, after a prescribed time has elapsed, or the like, by opening the valves 12a and 12b, the tritium density at this time can be correctly measured down to a low level.

Abstract: PURPOSE:To prevent lateral extension of an air intake pipe, to improve charging efficiency of intake air and to reduce weight of an air intake system by fixing an intake pipe collection part of an integrally formed air intake pipe only on a side wall of a cylinder block, and by fixing an intake pipe part only on a cylinder head. CONSTITUTION:An integrally formed air intake pipe 25 is constituted of an air intake pipe part 21 in the shape of U arranged at the side of a cylinder head 22 and a cylinder block 23 of an internal combustion engine, and a collector 24 as an intake pipe collection part in which each of the intake pipe parts 21 is collected at the upper stream side. In this case, as the collector 24 is fixed only on a side wall 23A of the cylinder block 23 to be separated from the cylinder head 22, and as an outer wall of a water jacket 29 is constituted of the side wall 23A, heat at the cylinder head 22 is difficult to be transmitted to the collector 24, thereby temperature rise in an intake air introduced to the collector 24 is prevented. Also, as the intake pipe part 21 is fixed only to the cylinder head 22, lateral extension of the integrally formed intake pipe 25 can be prevented.

Title: Photoresponsive apparatus
Inventor: NOGUCHI MASANORI
IPC: G01D5/58
Filed: 1979-08-31
Abstract: PURPOSE:To provide the apparatus with a simple construction by applying a light signal transmitted through a fiber to a heating element so as to expand a thermoresponsive material after conversion to an electrical signal. CONSTITUTION:A signal to be measured is transmitted from one end of fibers 11 and 12 on pulse width signals S1 and S2 of a light. The light signals S1 and S2 are irradiated on solar batteries 51 and 52 from the other end of the fibers 11 and 12 and electricl signal is outputted corresponding to the pulse width of the light and flows to heating elements 41 and 42. The heating elements 41 and 42 generate heat corresponding to the electrical signal so that thermoresponsive materials 31 and 32 are heated and expanded to stretch bellowses 21 and 22. The stretch of the bellowses corresponds to the light energy (duty ratio) of the light pulse width signal and a working lever 20 displaces according to the difference between the duty ratios t1/T and t2/T of the light signals S1 and S2 and the displacement drives a pointer through a link mechanism 5 thereby enabling indication of the magnitude of the signal transmitted. The transmission of the electrical signal is not needed thus simplifying the construction.
