Title: Method and device for determining priority sequence
Inventor: TAKAHASHI TATSUYA
IPC: G06F13/34
Filed: 1986-03-31
Abstract: PURPOSE:To determine a priority sequence based upon plural types of a priority sequence determining system by combining priority sequence determining parts of different forms. CONSTITUTION:Two equal opportunity priority sequence determining parts 10A and 10B are linked by a fixing priority sequence determining part 20. At present, when four request signals REQ0-3 are all inputted, the action of the determining part 10B to request signals REQ2 and 3 is stopped by the determining part 20. Request signals REQ0 and 1 are alternately selected and the service is received. When the request signals REQ0 and 1 are not inputted, the request signals REQ2 and 3 are alternately selected by the determining part 10B. When either of the request signals REQ0 and 1 is inputted again, the determining part 10B is stopped and the request signal determined by the determining part 10A is selected. Thus, the priority sequence can be determined based upon plural types of the priority sequence determining system.

IPC: H04N5/782
Filed: 1988-03-29
Abstract: PURPOSE: To reduce the crosstalk at the time of reproduction by performing the reproduction in a standard operation by a video head for long time operation.  
     CONSTITUTION: This video recorder has an oblique track 1 on a magnetic tape T for a standard operation and an oblique track 2 on the tape for a long time operation and a reproduction in the standard operation, that is, a reproducing by the track 1 having a width b1 is performed by a video head K2 which is intrinsically provided for the long time operation and has the gap of a narrower width w2 not by a video head K1 provided for the standard operation. That is, the width w2 is larger than the width b2 of the track 2, but is smaller than the width b1 of the track 1. Consequently. since the video head 2 can scan respective tracks of tracks 1 without scanning other adjacent tracks, the crosstalk is remarkably reduced.

Filed: 1986-03-31
Abstract: PURPOSE:To perform the turn-back test without adding a testing circuit by changing setting of a carrier frequency to a signal processing processor when the modulation processing is performed with the signal processing processor. CONSTITUTION:Transmission data from a center is transmitted to a communication line through an interface part 1, a modulating circuit 2, a D/A converting circuit 3, and a low-pass filter 4, and reception data from the communication line is taken into the center through a band-pass filter 5, a demodulating part 6, and the interface part 1. In case of the turn-back test, switches SW1 and SW2 are switched and the low-pass filter 4 and the band-pass filter 5 are connected with a loop. A signal processing processor 8 is used as the modulating circuit 2, and such data is set from a microprocessor to the signal processing processor that a modulated wave for which the demodulation processing is possible in the reception part side is sent. Thus, the turn-back test is performed because the signal processing processor transmits a modulated wave which can be demodulated in the reception side.

Title: Diaphragm controller
Inventor: KATSURAGAWA MITSUHIRO
IPC: G03B7/095
Filed: 1993-03-31
Abstract: PURPOSE:To widen the adjusting range of an opening confirming switch and to prevent a system error by supplying a driving pulse to a step motor by a specified driving amount in the case inputted diaphragm driving information shows a value under the specified driving amount from opening. CONSTITUTION:A light quantity setting circuit 31 calculates light quantity measured by a photometric circuit 30 in consideration of elements such as film sensitivity, shutter speed and a diaphragm value, and decides the number of diaphragm steps. The number of the diaphragm steps is converted into the number of driving steps of the step motor by a clock circuit and a distribution circuit 33. By deciding which direction of coils 12 and 13 a current is applied to by a step motor driver circuit 34 in accordance with the numbmer of steps, the step motor is rotated by an optional amount to be adjusted to specified diaphragm aperture. In the case the inputted diaphragm value shows that the diaphragm is driven in the diaphragm direction from the opening position by the step motor only by one pulse, driving by two pulses is performd. Thus, a diaphragm opening state detection switch is changed over within the range of two pulses.

Any residual chlorine left after the etching of the chlorine-containing gas mixture may be substituted or removed to some extent by the etching of the fluorine-containing gas mixture. After-corrosion can be prevented in this manner.

Title: Capacitance type sensor
Inventor: ODA HAJIME
IPC: H03K17/945
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive capacitance type sensor which can accurately prevent malfunctioning caused by noises, by arranging a structure which enables digital judgement of access or separation between objects or the presence of the objects. SOLUTION: An incremental/decremental counter 5 performs an increamental or decremental counting according to a gain or delay in the phase of each output pulse each time the output pulse of a first and a second delay circuits 2 and 3 is generated. For example, when the incremental/decremental counter 5 performs an incremental counting from 3 to 0 and performs a decremental counting from 0 to 3, the access or separation between objects or the presence of the objects is judged by a flip-flop 6 based on the capacitance of a converter 2a depending on individual outputs generated. Thus, malfunctioning due to noises can be prevented and the need for using a costly filler is eliminated.

Filed: 1982-05-04
Abstract: PURPOSE:To prevent the leaving of water in the inside by automatically operating all of the solar-heat collector and drainage in a heat collecting circuit and the like while positively introducing air on the operation of drainage. CONSTITUTION:When difference between a water temperature t1 in the solar heat collector and a water temperature t2 in a heat accumulator 13 by temperature sensors T1, T2 reaches a set value or more in the fine daytime, a circulating pump P1 is turned ON by a command from a controller 17 to accumulate heat. When the water temperature t1 in the collector 11 by the temperature sensor T1 reaches a set value or less, a drain valve V2 and an air vent valve V1 are opened by the controller 17 in order to prevent freezing. When the temperature of the outside air rises and the temperature t1 in the collector 11 by the sensor T1 reaches the set value or more, water supply is started, the controller 17 closes a feedwater valve V3 when a water level reaches a predetermined one, and the air vent valve V1 is closed when water supply is stopped. When insolation increases and (t1-t2) reaches the set value or more, the circulating pump P1 is turned ON - that is, it begins to be operated - while the air vent valve V1 is opened, and the air vent valve V1 is closed after several min. Accordingly, the drain valve and the air vent valve are opened and controlled automatically in response to the temperature of water when the temperature of the outside air drops and there is a danger of freezing.
