Title: A/d converter
Inventor: HASEGAWA JUN
IPC: H03M1/12
Filed: 1988-02-10
Abstract: PURPOSE:To eliminate the need for an operational amplifier to be required for shifting a level by providing a sample and hold means sampling and holding an input voltage and an A/D conversion circuit applying A/D conversion while a voltage subject to sample and hold by the sample and hold means as a reference voltage, on the same chip. CONSTITUTION:The sample and hold means applying sampling and holding to the input voltage, and an A/D conversion circuit 405 applying A/D conversion while the voltage subject to sample and hold is used as a reference voltage to the sample and hold means are provided to the same chip. The sample and hold means consists of a FET 401, a capacitor 402 and a buffer 403. The A/D conversion circuit 405 uses the black reference picture element output inputted from the sample and hold means as a reference voltage to apply A/D conversion to the output from an image sensor. Since the A/D conversion circuit 405 applies A/D conversion while using the black reference picture element output as the reference voltage in such a way, an operational amplifier shifting the level of the black reference picture element output into the reference voltage is not required.

Title: Hot-water reserving tank
Inventor: ODA SOU
IPC: F24S90/00
Filed: 1984-02-22
Abstract: PURPOSE:To uniformize the temperature distribution of hot-water in the main body of the hot-water reserving tank by arranging the heat medium returning port of a jacket type heat exchanger at a position lower than the center of the height of the heat exchanger. CONSTITUTION:The returning port 13 of heat medium is arranged at a lower position than the center of the height of jacket type heat exchanger 2. In case the temperature of the returning heat medium is lower than the temperature of hot-water at the height of the heat medium returning port 13, the heat medium is cooled soon when it enteres into the heat exchanger 2 and flows as shown by the broken-line arrow sign in the diagram, thus, the heat medium is heated at the lower part of the heat exchanger 2 and the whole of water in the hot-water reserving tank 1 is heated from the lower part thereof, therefore, the temperature distribution of the water is uniformized comparatively. In case the temperature of returning heat medium is higher than the temperature of hot-water at the heat medium returning port 13, natural convection is caused in the heat exchanger 2 and the returning high-temperature heat medium moves to the upper part of the heat exchanger 2 as shown by the full-line arrow sign 20. Accordingly, the heat medium is heated by the whole surface of the heat exchanger 2 and the temperature distribution of the hot-water may be uniformized.

Title: Measured-data storage device
Inventor: MORI SADAO
IPC: G01D9/00
Filed: 1993-02-22
Abstract: PURPOSE:To reduce the amount of data to be stored and to effectively utilize the limited memory capacity of a storage means by a method wherein an A/D converter, an operation means which approximates a digital signal spring by a prescribed approximation formula and which finds the coefficient of the approximation formula and the storage means which stores the coefficient of the approximation formula are installed. CONSTITUTION:Analog measured signals (voltages) Vin are converted into digital signals by an A/D converter 2, and the converted digital signals are stored sequentially in a memory 3. When the number of stored data reaches a prescribed number, the digital signals stored in the memory are dumped into a memory 4. Then, next digital signal strings are stored sequentially in the memory 3. Steps up to this time are controlled by a processor 5. When the digital signals are dumped into the memory 4, a processor 6 operates and controls the digital signals dumped into the memory 4. That is to say, a data feeding operation is performed to a plurality of digital signals dumped into the memory 4, and the coefficient of each term is found by a relational approximation based on a prescribed polynominal approximation formula.

Title: Digital convergence compensator
Inventor: MORITA KATSUMI
IPC: H04N9/28
Filed: 1981-03-04
Abstract: PURPOSE:To shorten the time of control for the writing correction of the degree of compensation, by changing the degree of compensation roughly when the shift of convergence is large and changing the degree of compensation by 1 when the shift of convergence is small respectively. CONSTITUTION:A control point to which the convergence compensation is desired is selected by a cursor key 2 on a control panel 1, and then the selected control point is displayed on a TV screen. At the same time, data A on the degree of compensation of convergence is taken into a register 21. In case the shift of convergence is large, a high-speed mode of control is selected by a mode switch 20 on the panel 1. Then an operation is carried out by a writing key 3 while looking at the screen, and as a result an N setting circuit 22 to which the compensating degree N (N>1) is previously set is selected. Then the data A is added to the degree N through an adder circuit 27 and written into a memory 5. The above-mentioned operation is repeated. When the shift of convergence becomes small, a low-soeed mode is selected with the switch 20 with an operation of the key 3. Thus a 1 setting circuit 23 is selected to correct the compensating degree by 1.

IPC: F24D13/02
Filed: 1987-02-14
Abstract: PURPOSE:To obtain a heating apparatus of which heat accumulating and heat radiating efficiencies are high, and of which safety properties are high, by forming layers of latent heat regenerative material of which phase transfer temperatures are different from each other on both sides of a heater. CONSTITUTION:In a heating apparatus A, a layer of latent heat regenerative material 3, consisting of latent heat regenerative particles 3a of which phase transfer temperature is comparatively high, is formed on a heat insulating material 4. A heater 1 is disposed on the latent heat regenerative layer 3. A latent heat regenerative layer 2, consisting of latent heat regenerative particles 2a of which phase transfer temperature is comparatively low, is formed on the heater 1. In this heating apparatus A, the temperature in the latent heat regenerative material on the radiating side can be prevented from lowering because heat is supplied from the latent heat regenerative layer 3 on the opposite side, of which temperature is comparatively high, when the latent heat regenerative material 2a on the radiating side radiates heat and its temperature is going to be low. In such a manner the effect to keep the room temperature constant can be expected.

Title: Safety apparatus for cassette type gas combustion appliance
Inventor: GOTO MASAKI
IPC: F23K5/00
Filed: 1988-02-15
Abstract: PURPOSE:To enhance safety in a gas combustion equipment, by mounting, in the proximity of the rear side of a valve chamber, a disc spring capable of moving in the reverse direction upon abnormal pressure rise, and fitting a check valve in the valve chamber so that a sealing member mounted thereon cooperates with a bearing surface of the valve chamber to cut off a gas flow in response to the reverse movement of the disc spring. CONSTITUTION:A gas bomb 1 is provided with a valve nozzle 2 which is biased in the outward ly projecting direction by means of a spring mounted therein. A valve chamber 4 is divided into two sections by a disc spring 7 which is mounted in the rear part of the chamber and is displaceable in the reverse direction in response to abnormal pressure rise in the chamber. A check valve 3 reciprocatably mounted in the vale chamber 4, abuts at its rear end against the disc spring and is urged into the closed position by a spring 6. A gas passage is opened in the vicinity of the rear part of the valve chamber 4. A sealing member 9 such as an O-ring is fitted in a groove 14 formed around the front part of the check valve. The sealing member 9 is normally in contact with a tapered front bearing surface 10 formed in a expanded section 16 of the valve chamber to permit a gas flow through the gas passage 5. When abnormal pressure rise occurs and the disc spring moves in the reverse direction, the check vlave 3 is allowed to move in the same direction such that the sealing member 9 abuts against a rear bearing surface 16. This results in shutting-off the gas flow through the gas passage 5.

Title: Monostable multivibrator circuit
Inventor: MURAYAMA YOSHIO
IPC: H03K3/355
Filed: 1985-02-20
Abstract: PURPOSE:To decrease the number of components and to attain miniaturization of the title circuit by starting the discharge of a capacitor connected to an externally mounted capacitor terminal in response to the potential change at an input terminal and selecting the time when the potential at the externally mounted capacitor terminal changes from the value at discharge start to a prescribed value as the pulse width. CONSTITUTION:When power is applied, since an output of a gate 50 is at a high level, a transistor (TR) 80 is turned off. Since the TR 80 is turned on, the level of an output terminal 9 is inverted from a low to a high level. In this case, since the output of a gate 60 changes to a low level because the output of the gate 50 is inverted from a high level to a low level, a TR 100 being turned on till now is turned off. Thus, the potential at the externally mounted capacitor terminal 10 falls down gradually to the low level. Thus, the level of the output terminal 9 being at high level so far changes from a high level to a low level and a pulse is generated from a monostable multivibrator.
