Title: Method for recovering performance of water-permselective pervaporation membrane
Inventor: MATSUOKA SACHIKO
IPC: B01D65/06
Filed: 1995-02-28
Abstract: PURPOSE: To provide a separation performance of a water-permselective pervaporation membrane deteriorated in separation performance. CONSTITUTION: The separation performance of the water-permselective pervaporation membrane is recovered by allowing the membrane deteriorated in separation performance to contact with an organic liquid having water content 3-40wt.% higher than an organic liquid to be treated. As a result, the recovery is executed as a module is mounted on a device. And the recovery is completed only by carrying out a simple operation that the water content in a liquid of object to be separated is increased and the shift from recovering treatment to normal operation is simply executed only by changing the composition of a feed liquid.

IPC: H03K19/086
Filed: 1990-03-16
Abstract: PURPOSE:To reduce noise and to prevent a waveform from being dulled by constituting an ECL ternary logical circuit of a transistor(TR) having a current switch function in accordance with the 1st and 2nd input groups and using input signals of three levels consisting of an 'L' level, an 'H' level and a +'H' level. CONSTITUTION:Inputs to be simultaneously changed in the same direction are impressed to any one or more of an A side input TR group 41 to 43 and any one or more of B side TR group 44 to 46, and if a voltage exceeds a reference voltage when the A input side is turned from 'L' to +'H' and the B input group is turned from 'L' to 'H' (+ high level), the TRs 41 to 43 are turned on, the TR 44 is turned on and the TR 45, 46 are turned off. When the potential of the B input group is turned to higher than that of the A input group, the TRs 41 to 43 are turned off and only the TRs 45, 46 are turned on. Thereby, an OR output is turned to 'L'. When the potential of the B input is turned to +'H', a NOR output is turned to 'H' and ternary logical operation is executed.

Title: Device for preventing diagonal fitting of multiple-start thread
Inventor: TAWARA YOSHIMASA
IPC: B65D41/04
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To prevent the diagonal fitting in which a thread ridge of a cap female screw is mistakenly engaged with a screw groove by removing a part of thread parts in a multiple-start thread. SOLUTION: For example, when a cap is fitted to a male screw of a threaded head part 1 of a container in an inclined manner, a ridge of one thread of two cap females screws is irregularly engaged with a screw groove (b) over a thread B before it is engaged with a screw groove (a) immediately below a regular thread A of an ideal male screw of a container. However, because the thread B before engagement with the screw groove (a) is removed, the screw is engaged with the screw groove (a) immediately below the thread A, and the diagonal fitting becomes impossible. At the same time, the regular thread B of the regular container at the position where the ridge of the other thread of the female screw of the cap is separated by 180 deg. in the rotational position, is removed in advance, the diagonal fitting becomes impossible.  Thus, before one regular rotation is completed, the screw is engaged with the rest of the threads B and screw groove (b), the male and female threads are firmly pressed against each other, and the regular fitting of the cap is completed.

Title: X-ray equipment
Inventor: HIRABAYASHI TOSHIHIRO
IPC: H05G1/54
Filed: 1984-04-07
Abstract: PURPOSE:To reduce noise and save power consumption by detecting temperature variation of an X-ray tube device and controlling rotation and stop of a cooling fan. CONSTITUTION:The second temperature detector 7 which operates at a specified temperature set between atmosphere temperature and allowable limit temperature is installed on an anode side of X-ray tube device 4. The detector 7 detects temperature variation caused by use of the X-ray tube device 4. By detected signal, a cooling fan is rotated when temperature of the X-ray tube device 4 is high, and the cooling fan is stopped when temperature is low. Since the cooling fan 5 is rotated only when cooling is required, noise to a patient is reduced and power consumption is saved.

Abstract: PURPOSE:To alarm upper limit and lower limit burn-outs by inserting diodes in the two sides of a bridge circuit including the side where a temperature measuring resistor is inserted, letting a light emitting element emit light through conduction of the diodes and operating an alram by the light received thereby. CONSTITUTION:Two sides of a bridge circuit 11 are formed by a temperature measuring resistor RTD and a span adjusting resistance RS, resistance R1. When the A or C point of the bridge circuit 11 disconnects, the positive polarity potential of a power source Eb causes a transistor Q1 to go ON, then current flows in a diode D1 and light emitting element PCD, causing the element to emit light. The light thereof enters a photo detector PCT, which then goes ON to let the nagative input part of a DC amplifier A2 be grounded through up terminal 14 and PCT. As a result, the 1/2 voltage of a power source Ec determined by resistances R5, R6 is applied to the positive input part of A2 and the high voltage signal is applied to the constant current circuit 13 and the constant current above 100% flows from the circuit 13, thereby operating an alarm device 17 connected to a transistor Q3.
