Title: Hot water feeding device
Inventor: UNISUGA SHIGERU
IPC: F24H1/18
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To prevent inflow of mixture water in a hot water tank through a reverse flow of most of mixture water in a hot and cold water mixing tank when a hot water pump is stopped by a method wherein a rise part rising to a level higher than that of water in the hot cold water mixing tank is formed and a small air blow-in hole is formed in the vicinity of a top part. SOLUTION: An inverted U-shaped rise part 7A rising to a level higher than a water level L in a hot cold water mixing tank 2 is formed on the downstream side of a stop valve 4, and a small blowin a hole 20 is formed in a part positioned in the hot cold water mixing tank 2. When a hot water pump 6 is stopped, air flows in the rise part 7A through the air blow-in hole 20 and since the occurrence of siphon phenomenon is blocked, mixture water in the hot cold water mixing tank 2 is prevented from the occurrence of reverse flow over the rise part 7A. Hot water in a hot water transfer pipe 7 situated upper stream from the rise part 7A is prevented from a reverse flow by a stop valve 4 and a check valve 5. This constitution prevents the hot cold water mixing tank from being empty and prevents the occurrence of overflow over the hot water tank and contamination of the vicinity thereof.

Abstract: PURPOSE:To attain automatic character segmenting, by segmenting character string at first and then segmenting at characters at each character string. CONSTITUTION:A picture signal for a sheet of paper inputted from an input terminal 1 is once stored in a picture memory 2. This stored picture signal is read out according to a signal of a memory control circuit 3, the number of black picture elements is counted at a counter 4 and written in a y projection memory 6. The operations are done for all scanning lines by setting a write address by a memory control circuit 7 according to a control signal of a microprocessor 10. The value of the y projection is read in the microprocessor and if the value of the y projection is larger than a prescribed value, it is decided as a character section and if smaller, it is decided as a part between lines.
Patent JP-H0487194-A (JP)
Title: Inverter device
Inventor: KISHIMOTO NAOKAGE
IPC: H05B41/392
Filed: 1990-07-25
Abstract: PURPOSE:To prevent flowing of an excessive power-supply shortcircuiting current by sensing eventual existence of a voltage at the connection point of partial voltage capacitors connected parallelly with a No.2 switching element, and thereby knowing that No.1 switching element is turned off. CONSTITUTION:A series circuitry of partial voltage capacitors C7, C8 is connected parallelly with No.2 switching element Q2, and sensing of No.1 switching element Q1 being turned off is made according to eventual existence of a voltage obtained at the connection point of these capacitors C7, C8. This allows elimination of delay in triggering a mono-stable multi-vibrator MV1 resulting from its input capacitance C6 in a switching control means X2. This prevents a power- supply shortcircuiting current flowing through No.2 diode D2 and the No.2 switching element Q2 when this Q2 is turned on.

Title: Double structure method of input and output device
Inventor: SHIMIZU HIROYASU
IPC: G06F13/00
Filed: 1982-11-15
Abstract: PURPOSE:To simplify the double structure control by providing a bus controller between the system bus of a computer and to input/output devices having the same function and proper addresses respectively. CONSTITUTION:A system bus 3 of a CPU (not shwow in the diagram) is connected to two input/output devices 1 and 2 having the same function and different addresses via a bus controller 7. The data is transferred between the bus 3 and controllers 1a and 2a of the devices 1 and 2 by the controller 7 in response to the control signal given from the CPU. As shown in the diagram A, the data can be transferred via the controller 7 with devices 1 and 2 defined as devices different from each other. Otherwise the devices 1 and 2 are duplicated to transfer the same data as shown in the diagram B. In the case of duplication, the addresses are apparently coincident with each other for devices 1 and 2. Then the CPU performs reading/writing with just a single acess. In such a way, a double structure is easily obtained for two input/output devices.

Abstract: PURPOSE:To attain the message transmission from the absence device even when the operator is absent by providing a means allowing a telephone call means to make calling when a voice message transmission request is set from an input means and sending a message upon the receipt of a notice representing the presence of a reply. CONSTITUTION:When a picture signal (PIX) is sent from a facsimile equipment 50 and the setting of telephone call is given, a control section 31 sends a control signal PRI-EOM (or PRI-EOP) requesting the intervention of the operator of the opposite party. When a telephone set 41 replies in response to the signal, the control signal PIP-EOM representing the need of the intervention of the operator is sent from an opposite facsimile equipment 40.

By this constitution, it is prevented that resonators 6 (6a - 6e) are continuously resonated on the basis of the signal from the adder 5 and the intensity of each frequency component is obtained. The outputs of the resonators 6 are inputted to a microcomputer 7 and, in this microcomputer 7, the renewal setting of a background level is prohibited on the basis of the difference between the pattern of the intensity change of the characteristic frequency component of the sensor, which is inputted through the resonators 6 on the basis of the detection signal from a crank angle sensor 8, and a predetermined standard change characteristic.
