Title: Diaphragm for producing alkaline ionized water
Inventor: KAWAOKA KENJI
IPC: C02F1/46
Filed: 1993-04-16
Abstract: PURPOSE:To lower an electrolytic voltage by welding a nonwoven fabric having an apparent thickness to both sides of a film having an ion-exchange group or a film free of an ion-exchange group in a specified coating weight in the electrolytic diaphragm for generating alkaline ionized water. CONSTITUTION:A nonwoven fabric having 30-200mum apparent thickness is welded to both sides of a film having an ion-exchange group or a film free of an ion- exchange group, in 10-100g/m<2> coating weight to constitute the electrolytic diaphragm. A cation-exchange group is appropriately used as the ion-exchange group, and a perfluorosulfonic acid cation-exchange group is preferably used as the ion-exchange membrane having an cation-exchange group. Meanwhile, an aromatic polyimide film, polysulfone porous film. etc., are used as the film free of an ion-exchange group. As a result, calcium carbonate is not deposited directly on the diaphragm, and hence the electrolytic voltage is not raised.

Title: Multi-point conference system, its terminal equipment and multi-point conference method
Inventor: HAMADA NOBORU
IPC: H04N7/15
Filed: 1994-04-28
Abstract: PURPOSE:To provide a multi-point conference system capable of improving operability by dearly displaying the change of recognition and informing an operator of the change of the recognition without moving the viewpoint of the operator, and without limiting the number of points capable of acquiring the recognition. CONSTITUTION:In the multi-point video conference system using MCU, the own picture of the terminal equipment at a point having the recognition is projected on the display device of the terminal equipment having no recognition at the other point. When the operator of the terminal equipment desires to acquire the recognition, he depresses recognition request key 14 and outputs a recognition acquisition request to MCU. When the recognition can be acquired by a response from MCU, the terminal equipment changes the color of a recognition display part 11 being the display frame of the own picture 12 projected on the display screen 34a of the display device and informs the operator of that the recognition can be acquired. The operator can easily and securely know the acquisition of the recognition without moving a viewline.

IPC: H03K23/40
Filed: 1984-06-04
Abstract: PURPOSE:To output a count value of a clock signal while dividing it N-time by x-bit each by inputting an AND value of carry outputs of the 1st-(i-1)th counters to the 2nd enable terminal of the 1-th counter. CONSTITUTION:A value of an output signal 7 of a counter A is ''0'' when a 1/3 frequency division signal 2 is at a low level. When the 1/3 frequency division signal 2 goes to a high level, ''0'' is loaded, and the counter a counts up and the value of the output signal 7 of the counter A changes from ''0'' to ''1''. Since the 1/3 frequency division signal 2 goes to a low level during two clocks afterward, the value of the output signal 7 of the counter A remains ''0'' and unchanged. When the 1/3 frequency division signal 2 goes to a high level, a value ''1'' of the preceding output signal 7 is fed back and becomes an input to the counter A, loaded and then counted up, then the value of the output signal of the counter A changes from ''1'' to ''2''. Then the counter is counted up at three clocks each.

Filed: 1987-05-13
Abstract: PURPOSE:To secure earthing without being affected by vibration in the rotation of a rotary sector by sandwiching a part which can shield a body to be detected and the inside of a sensor intermittently between two conductors. CONSTITUTION:The rotary sector 8 is rotated by a motor 1. At this time, a detection electrode 9 is exposed intermittently through a through-hole.

Title: Fm receiver
Inventor: OKUBO BUNICHI
IPC: H04B1/26
Filed: 1991-05-21
Abstract: PURPOSE:To prevent characteristic deterioration due to a multipass signal (reflected wave) in an FM receiver to be mounted on a vehicle. CONSTITUTION:Since an FM carrier is AM-modulated corresponding to the delay time of the multipass signal when a multipass signal exists, an AM component in the AM-modulated FM carrier outputted from a front end (high frequency amplifier) 12 is detected by a level detector 3 and detected AM component is controlled so as to be canceled by a variable gain amplifier 2 by using the detection level of the AM component as a control signal to remove the AM component from the FM carrier. Thus characteristic deterioration due to the AM modulation of the multipass signal, especially a pulse-like noise generated at the time of inputting the multipass signal at random which is the maximum problem of multipass operation, can be effectively removed.

Abstract: PURPOSE: To obtain an instantaneous speed signal which is positive or negative depending on the direction of motion of a moving body, by generating a signal of frequency corresponding to the speed of the moving body and by detecting the change in the signal within a prescribed time and the direction of motion.  
     CONSTITUTION: When a motor is rotating, signals different in phase by 90° from each other are generated by an encoder PSG and amplified at AMP1, AMP2. The amplified signals are shaped to rectangular waves at VC1, VC2.

Filed: 1979-09-11
Abstract: PURPOSE: To reduce the sensor lead wire with less number of transducers, by providing the transducer for the detection of elastic wave excitation and detection near one end of the magnetostriction thin band, and taking another end as the reflection end of elastic waves.  
     CONSTITUTION: When pulse current flows to the coil 8 as the transducer at time t 0 , the elastic wave excited at the magnetostriction thin band 1 due to magnetostriction effect propagates toward the both ends. Since the end processed for sound absorption absorbs the elastic waves, the coil 8 receives the reflected elastic waves from the retaining plate 7 direction at the time t 1  after (t 1 -t 0 ) from the exciting time t 0 . The presence of the frost adhesion is judged for the magnetostriction thin band 1 from the detection value of reception. Further, the driving pulse ϕ 1  is given to the coil 8 via the driving circuit 9, the clock pulse signal ϕ 2  is given to the D type flip-flop 12 after (t 1 -t 0 ), and judged at the comparator 10 as an alternative method.

By such a process, the carrier C1 which has gone out to the side of the surface of the magnetic brush is mixed with the carrier C2, and by a stirring action of this time, a toner concentration distribution in the radial direction of the sleeve is averaged. In such a way, the collecting property of a toner becomes satisfactory, and the cleaning property can be improved.

Abstract: PURPOSE:To elevate the dV/dt rating, by lowring a conduction current flowing  through the second junction of a semiconductor switch consisting of 4 layers, when  voltage is applied suddenly. CONSTITUTION:A diode 11 is connected in parallel between an anode A and an (n) base N1 of a PNPN switch 1. In case when transient voltage has been applied to the PNPN switch 1, a base current portion of a P1N1P2 transistor is made to branch and flows to the diode 11, and an AC current amplification factor hp of the P1N1P2 transistor drops. Accordingly, a transient current flowing to a resistance RGK 2 through the second junction is reduced, and the dV/dt rating is elevated.
