Title: Water kettle
Inventor: MORI KEIICHI
IPC: F23N5/14
Filed: 1978-12-11
Abstract: PURPOSE:To reduce the number of overshoots of hot water in a water kettle and prevent apprehensions of a scald and abrupt decrease of water temperature by proportionally controlling the combustion amount of a burner upon detection of the exhaust hot water temperature from the kettle. CONSTITUTION:Water heat exchanged by a heat exchanger 2 via a burner 6 is supplied as hot water from a faucet 3. The exhaust hot water temperature is detected and converted to an electric signal by a water temperature detector 7, and the signal is applied to a control circuit 8 to control the opening of a fuel control valve 5 to thereby control the combustion amount of a burner 6. When the water temperature is lowered, an output from a circuit having a thermistor 11 for enhancing the resistance and an operational amplifier 20 forming an integrating circuit controls a current applied to a proportional valve coil 29 for operating the valve 5 from a proportional circuit 22. When the supply water amount is increased, the signal of an operational amplifier 18 forming a differentiating circuit is amplified by an operational amplifier 22 to accelerate the response of a valve.

Title: Steam type injection valve
Inventor: FUKUYOSHI TADASHI
IPC: F02M43/00
Filed: 1985-07-12
Abstract: PURPOSE:To improve combustion characteristic, by forming a waterdrop sump at the bottom of a steam chamber and connecting the waterdrop sump to a pressure reducing valve in a steam type injection valve of a diesel engine. CONSTITUTION:When a cam turns to cause a valve stem 2 to lift, a valve 33 leaves a valve seat 34, steam in a steam chamber is injected into a nozzle 35, and fuel in a fuel storage chamber 4 is pushed out from thin holes 7... through a fuel passage 5. As a result, the fuel is atomized by a jet stream of the stream and injected into a combustion chamber 21 through the nozzle 35. Since the steam chamber 3 and the fuel storage chamber 4 are separately constructed each other, the steam does not contact the fuel until the valve seat 34 opens so that the fuel is prevented from changing its quality. In addition, since a waterdrop sump 10 is formed at the bottom of the steam chamber 3 to be connected to a pressure reducing valve 13, the steam pressure is kept constant, and since waterdrop produced is removed as drain, atomizing characteristic is improved to obtain excellent combustion performance.

Filed: 1990-06-12
Abstract: PURPOSE:To increase the area of orientation control of molecules, etc., and to increase the number of picture elements by providing the orientation control films formed of coated films of modified protein on supporting plates. CONSTITUTION:Transparent electrodes 12 are formed on substrates 11 and after the orientation control films 13 are formed thereon, a resin 14 is printed. Two sheets of the liquid crystal supporting plates 15 are stuck to each other and a liquid crystal 16 is injected from an aperture and the aperture is sealed to complete a liquid crystal cell. The control films are formed by subjecting the coated films essentially consisting of the protein to an orientation treatment and further exposing the films to environment of 30 to 60 deg.C and >=70% humidity. Since the protein molecules and assemblage thereof exhibit good orientation, the orientation uniform over the entire surface of the element is attained easily at a low cost if this film is applied to the liquid crystal element. Above all, the uniform orientation is attained at the low cost with the liquid crystal element formed by using a liquid crystal exhibiting a ferroelectric property while the bistability is perfectly maintained over a long period of time.

Title: Magnetic recording and reproducing device
Inventor: FUJIMURA MASAYUKI
IPC: G11B15/087
Filed: 1981-09-30
Abstract: PURPOSE:To detect assuredly a program discriminating signal, even if a running speed of a tape fluctuates by securing a contact between a magnetic tape of the reproducing side and providing a dummy head incorporating an MR element. CONSTITUTION:An MR element is incorporated into a dummy head 3, and the head 3 is set at the position where a contact is secured to a magnetic tape 1a or the program discriminating signal can be detected. It is possible to detect the control signal from a change of the voltage value and in response to a change of a magnetic field produced from the tape 1a by flowing previously a certain current to the MR element. The MR element is not proportional to the magnetic flux differential dphi/dt and receives no effect of the travelling speed of the tape to ensure the assured detection of the control signal. In such constitution, the program and the control signal are recorded and then the program is reproduced by a head 2. In a reproduction mode, the control signal is also detected by the head 3. Then the control signal is detected assuredly by the head 3 in the fast forward and rewind mode of the tape 1a.

Filed: 1987-06-20
Abstract: PURPOSE:To attain edit recording for a section of start, end tape designation position by operating and setting one or both increase/decrease correction data of a start/end point reference data. CONSTITUTION:Data of a tape reproducing position before by a specified value of start/end from a start/end tape designated position is set in a storage section 3 as the start/end point reference data through operation. A correction counter section 4 sets the increase/decrease correction data of the start/end point reference data and the output timing of the control signal of recording start/end is deviated from the timing based on the specified value by the quantity of the increase/decrease correction data. Thus, the start/end timing of the recording of a video tape recorder at the recording side is corrected automatically in response to the operation delay time of a video tape recorder at the recorder side. Thus, the edit recording is applied for the section of the start/end tape designation position.

Title: Resistance change detecting circuit
Inventor: KOSUGE MINORU
IPC: G11B5/39
Filed: 1983-08-24
Abstract: PURPOSE:To attain long service life of a resistance change element by connecting a couple of common base transistors (TR) across the resistance change element so as to keep the current density of the resistance change element constant. CONSTITUTION:When a resistance value of a magneto-resistance effect type magnetic head 1 is changed from RMR to (RMR+DELTARMR) because of the magnetization of a medium, a voltage across the magneto-resistance effect type magnetic head 1 is unchanged because emitters of a couple of the common base TRs 4, 5 suppress the change, and only the current changes from IMR to (IMR+ DELTAIMR). Since the terminal voltage of the magneto-resistance effect type magnetic head 1 depends on the difference of the base potentials Vref+ and Vref- of a couple of the common base TRs 4, 5 and is constant always, even if the magneto-resistance effect type magnetic head 1 is worn, the current density is constant.
