Title: Video signal recording device
Inventor: OOTA YOSHIHIKO
IPC: H04N5/782
Filed: 1981-12-18
Abstract: PURPOSE:To record and form patterns equivalent to tape patterns by a currently used 2-head system VTR, by appropriately setting the interval between the main  head and auxiliary head of the 1.5-head system and the fitting height. CONSTITUTION:A magnetic tape 1 is wound around a rotary drum 16 and a lower fixed drum 19 at an angle range, a little smaller than 360 deg., and the tape is run in the direction of arrow X. A main head HA and an auxiliary head HB, each of which is composed of a pair of heads having different azimuth angles, are installed to the rotary drum 16 at an angle (alpha) interval which is a little larger than the angle during a section where the heads HA and HB cannot contact with the magnetic tape 1 and with a height difference (d). When the angle alpha and the height difference (d) are appropriately set, patterns recorded on the magnetic tape by the heads HA and HB become ones shown by the TA1, TA2, TB1, and TB2 in the diagram, and the combined pattern of patterns recorded by both heads becomes equivalent to the pattern of a 2-head VTR.

Title: Hot and cold water mixing device
Inventor: SHIBA BUNICHI
IPC: G05D23/13
Filed: 1988-08-18
Abstract: PURPOSE:To make the stability of hot water temperature satisfactory with a simple structure by providing such an arrangement that a control valve driving means is driven in accordance with a detection signal indicating a temperature of a mixing passage so as to operate a control valve which therefore takes a position at which the temperature of mixed hot water is controlled. CONSTITUTION:If a control means 23 determines, in accordance with a signal from a mixed hot water temperature detecting means 17, that the present temperature of mixed hot water is higher than a set hot water temperature, the control means 21 delivers a signal to a control valve driving means 22 in order to increases the flow rate of water while decreasing the flow rate of hot water. Accordingly, a control valve 19 increases the flow rate flowing through a water side second communication passage 18a while decreasing the flow rate of hot water flowing through a hot water side second communication passage 18b so that the pressure of a water side back pressure chamber 14a increases and the pressure of a hot water side back pressure chamber 14b decreases, giving a pressure differential which is applied to valve members 13a, 13b and a mixing valve 13 that therefore move in a pressure differential decreasing direction. Accordingly, the opening degree of the mixing valve 16 communicating a water passage 11 with a mixing passage 16 is increased to increase the flow rate of water while decreasing the flow rate of hot water, thereby the temperature of the mixed hot water in the mixing passage 16 decreases to the set temperature.

CONSTITUTION:To one terminal of a voltage comparing circuit 6, a voltage of a divided voltage input terminal 2 is inputted, and to the other input terminal, a voltage VP of the second reference voltage 7 is inputted, a voltage of the terminal 2 and the voltage VP are compared, and a voltage corresponding to its result is outputted from an output terminal 8. Subsequently, the first reference voltage VR and the voltage VP are set to VP/VR=b>1, that is, VP is set higher than the voltage VR. Accordingly, even if a voltage dividing ratio 1/a of a variable type voltage dividing circuit 4 is set to any value, an overvoltage is detected at the time of exceeding (b) times (b>1) of an output voltage Vout in its stationary state, and an output voltage of the terminal 8 is varied to a correct value in accordance with the detection. In such a way, even if the output voltage is varied by a voltage control circuit 1, an overvoltage detecting point can be varied in accordance with its output voltage, and an optimum overvoltage detection which can protect enough a load circuit can be executed.
