Title: Abnormality detecting device for power voltage
Inventor: ISHII SHIGEKI
IPC: H02H3/24
Filed: 1994-05-02
Abstract: PURPOSE:To provide an abnormality detecting device for power voltage which detects the drop of power voltage if occurs and also decides whether the voltage drop is caused by a power failure or not. CONSTITUTION:The DC voltage which is proportional to the output voltage of an AC power supply 1 is outputted at a point (b), and the pulses are outputted at a point (a) in each cycle of the output voltage of the power supply 1. A capacitor 17 is charged by these output pulses. If a power failure occurs in the power supply 1, the voltage of the point (b) and the inter-terminal voltage of the capacitor 17 drop and the outputs of both comparators 18 an 19 are set at 'H'. Then an LED 25 is turned on. When the power voltage drops by the factors other than the power failure, the output of the comparator 18 is set at 'II' with the output of the comparator 19 set at 'L' respectively. Thus an LED 26 is turned on.

Abstract: PROBLEM TO BE SOLVED: To enable the searching of the current route of wiring without necessitating a lead wire for sending a reference signal, and reduce the time for searching the current route. SOLUTION: In this method, a signal from a signal generator 1 is applied to wiring, the applied signal is detected by a lock-in amplifier 12, and the flowing path of the applied signal is pursued, thereby searching the current route of wiring.

From one side of the wiring, the added signal is applied, and the current is received on the wiring route. A reference signal of f1Hz is formed on the basis of the signal component of nf1Hz.  By using the reference signal, the sinusoidal wave of f1Hz in the current is detected by the lock-in amplifier 12, and the current value and the phase difference of the detected sinusoidal wave of f1Hz are measured, thereby detecting the flowing direction of the signal current applied to the wiring.

Title: Production of element for separation membrane
Inventor: OKUMURA YOSHINOBU
IPC: B01D71/02
Filed: 1986-04-22
Abstract: PURPOSE:To produce a separation membrane layer consisting of fine particles without providing a substrate layer on the surface of a base plate by immersing a molded material of the base plate having the same calcination temp. as the separation membrane layer without calcining the molded material into slurry suspended with the particles constituting the separation membrane and thereafter drying and calcining the molded material. CONSTITUTION:A resin binder is blended with the particles having coarse particle diameter as a raw material for a base material and the mixture is kneaded and the kneaded material is pressurized and molded into a prescribed shape and dried to obtain an uncalcined molded material of the base plate. This uncalcined molded material is immersed into slurry suspended with the particles constituting a separation membrane to stick the particles on the surface thereof. The spaces of the particles incorporated in the molded material of the base plate are larger than the particles constituting the separation membrane but the resin binder is filled to the spaces of the particles and therefore a pore larger than the diameter of the particles constituting the separation membrane is not substantially present. Therefore the fine particles constituting the separation membrane do not infiltrate into the molded material of the base plate. Then the resin binder is gasified and lost by drying the molded material and performing dewaxing treatment and calcining it and an element for the separation membrane is obtained.

IPC: G11B27/17
Filed: 1992-04-15
Abstract: PURPOSE:To obtain the sound recording time in a short time by measuring a rotation period of a reel at one side and calculating the recording time with the use of a specific equation. CONSTITUTION:The rotation of the reel 1 at one side of two reels 1, 2 on a cassette tape 5 is detected by a rotation detecting part 7, and the rotation period of the tape 5 is measured from an output signal of the detecting part 7 by a rotation period detecting part 10. By a rotation counting part 11, the number of rotation of the reel 1 is detected in the manner of counting a signal of the detecting part 7. By using these results, the recording time TC of the tape 5 is obtained by a recording time arithmetic part 16 based on the equation. In the equation, T1 is the rotation period of reel 1 under the feeding state with constant speed at the position fed by the leader tape portion from the start/end of the tape, and T2 is the rotation period under the tape feeding state with constant speed at the position fed by K rotations from the position where the period T1 is measured. Further, TNR is the rotation period of reel 1 under the unwinding state at the position where T1 is measured. Then, the recording time is obtained in a short time while taking the thickness of tape 5 into consideration by means of providing the detecting part 7 on only the reel 1 of one side.
