Abstract: PROBLEM TO BE SOLVED: To prevent the introduction of high-temperature hot-water in a hot-water storage boiler body into a bathtub without reducing the temperature of the hot-water to a proper temperature. SOLUTION: An automatic hot-water filling device for bath mixes hot-water from a hot-water storage boiler body 10 into water from a bypass passage 23 through a fixed type wax thermo mixer 30 and pours hot-water, having a fixed temperature, from an automatic hot-water supplying passage 40 for bath into a bathtub 50 through a circulation passage 60 for additional heating of bath when bath automatic hot-water filling operation is commanded.  In this case, the automatic hot-water filling device for bath is constituted so as to detect a supplying temperature of hot-water during bath automatic hot-water filling operation employing a bath temperature sensor 66, provided in the circulation passage 60 for additional heating of bath, and when the bath automatic supplying hot-water temperature, detected by the bath temperature sensor 66 during bath automatic hot-water filling operation, has become higher than the fixed temperature by a given temperature or more during automatic hot-water filling operation for bath, a controller 70 decides that the fixed type wax thermo mixer 30 is fixed to the high-temperature side and stops the bath automatic hot-water filling operation.

Filed: 1984-05-14
Abstract: PURPOSE:To obtain a video signal detection circuit capable of simplifying the circuit constitution by executing measurement by a soft timer during a period when a horizontal synchronizing signal or a vertical synchronizing signal is measured. CONSTITUTION:When a count start signal is inputted to the 1st input terminal 7 by instructions from a microprocessor, a flip-flop 9 is set, and its output terminal 11 becomes ''L'' level. At this time, a horizontal synchronizing signal inputted to an input terminal 4 is inputted to a counter 12 through an OR circuit 5, and the counter 12 starts counting of the horizontal synchronizing signal. Then, upon elapsing of a period T after the count start signal is inputted, a count stop signal is inputted to the 2nd input terminal 8. Then the flip-flop 9 is reset, and its output terminal 11 becomes ''H'' level. Thus the counter 12 completes the counting of the horizontal synchronizing signal, By deciding the contents of the counter 12, the detection whether or not a station is selected is made.

Title: Magnetic control type switching power supply device
Inventor: YAGISHITA YASUAKI
IPC: H02M3/28
Filed: 1991-04-02
Abstract: PURPOSE:To easily delay the rise of an output voltage without using a switch or the like connected to a load in series, to improve the efficiency of power supply, to suppress heat generation, and to reduce the number of parts by allowing a reset current to flow only for a fixed time. CONSTITUTION:When voltage V1 is impressed to the terminals 3, 4 of another power supply before impressing voltage to a magnetic amplifier SR, voltage E1 divided by resistors R2, R3 is instantaneously impressed to the plus terminal of a comparator A. The voltage E2 of the minus terminal is boosted in accordance with the charge of a capacitor C1 through the resistor R1. Since E1>E2 is held until charging time, the comparator A is held at the ON state, a transistor Q1 is turned on, a photocoupler PC is driven, and a reset current is allowed to flow into the magnetic amplifier SR. Since E1<E2 is set up after the charging time, the comparator A is turned off, the reset of the magnetic amplifier SR is canceled, and an output voltage is raised. In addition, a transistor Q2 is controlled by a control signal outputted from a reset control circuit 2 to hold the output voltage at a fixed value.

Filed: 1988-04-22
Abstract: PURPOSE:To obtain a high transmission rate even in case of the extinction state of the idling state by applying a preparatory light emission signal to an optical transmission module before a transmission signal with respect to an optical communication equipment of intermittent transmission. CONSTITUTION:When a transmission start signal (b) is outputted from a transmission start signal generating part 3, an off-delay circuit 5 outputs an off-delay signal of the transmission start signal (b), namely, a preparatory light emission signal (c) to a transmission control circuit 6. The transmission control circuit 6 starts to output a transmission signal (d) by the input of this signal (c), and OR between the preparatory light emission signal (c) and the transmission signal (d) is operated by an OR gate and this OR signal is inputted as a drive signal (e) to an optical transmission module 8 and is transmitted as an optical transmission signal (f). When an optical reception module 12 of an optical communication equipment of the other system receives the transmission signal including the preparatory light emission signal after the extinction state of the idling state, the transmission signal received after the preparatory light emission signal is stably received because the time of the preparatory light emission signal part is set to a length required for sufficient rise of the threshold level of the optical reception module 12.

Abstract: PURPOSE:To enable stabilized take-up of helically woven fabric without any surface damage by stacking up the helically woven fabric on a turn table in a spiral by allowing a fabric holding members and a fabric driving members to work intermittently as they hold the fabric alternately. CONSTITUTION:In the take-up of helically woven fabric made of, for example, carbon fibers as a fabric material for reinforcing high-strength composite materials in a round disk or conical form, the warp yarns Sp1 and Sp2 are opened by the heald frames 21, 22 and the weft yarn Sf is picked and incorporated into the cloth fell F with the reed 22 to form woven fabric S. The fabric S is held with a plurality of holding members 11 and driving members 12 which are alternately arranged along the periphery of the spiral 19. When the holding members 11 are in the releasing positions, the driving members 12 are in the holding positions and move ahead in the arrow direction K1 to send out the fabric S on the turn table 36. The turn table 36 makes intermittent rotation synchronously to take up the fabric S helically, and it goes down in the axial direction while the fabric is piled up, until reaching the prescribed position where the fabric S is sent out.

Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To stabilize an angle of a recording head to a medium to be recorded by detecting a contact between at least three contact parts to the medium and the medium. SOLUTION: An apparatus 1 is manually moved to a medium S to be recorded, whereby a predetermined recording is carried out. In this case, a discharge opening 2a of a recording head 2 is exposed to a lower face of the apparatus 1 and arranged opposite to the medium S to be recorded. The apparatus 1 has four rollers 3 as contact parts to the medium S to be recorded. The rollers prevent an inclination of the recording head 2 to the medium S to be recorded. Moreover, a touch sensor 4 set to each roller detects a contact state and an encoder 5 set to a shaft 3a of the roller 3 detects a move amount of the apparatus 1. A control means 6 transmits image signals to the recording head based on information from the touch sensors 4, encoder 5 and the like, whereby ink is discharged from the discharge opening 2a to record images.  When the contact state of each roller 3 is insufficient, a warning means 8 gives warning.
