Title: Hysteresis comparator circuit
Inventor: AMANO NOBUTAKA
IPC: H03K3/0233
Filed: 1991-09-27
Abstract: PURPOSE:To facilitate the adjustment of an inverting level by operating the hysteresis comparator at a voltage being a multiple of K of an input voltage by an amplifier. CONSTITUTION:An input voltage at an input terminal 1 is divided by a resistor 2 and a variable resistor 3 and inputted to a noninverting input terminal of an amplifier 4 as a vin, an output of the amplifier 4 is connected to the noninverting input terminal of the hysteresis comparator circuit 5 and a reference voltage REF is connected to the amplifier 4 and an inverting input terminal of the hysteresis comparator circuit 5. In this case, since the amplifier 4 has an amplification factor of a multiple of K, an output voltage vo is KX(vin-Vref) and since the hysteresis comparator circuit 5 receives the output voltage vo of the amplifier 4 and the reference voltage Vref and is operated by them, a hysteresis voltage vH1 is 1/K of a hysteresis voltage vH0 of the hysteresis comparator circuit 5. Even when the voltage vH0 is selected to be several tens of mV, the hysteresis voltage vH1 is decreased by selecting the amplification factor K of the amplifier 4 to be 10.

Title: Waterproof switch structure
Inventor: TANIHIRA OSAMU
IPC: H01H13/02
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To provide an indicator function having high visibility, and to realize a stable click feeling by arranging one end surface of a light transmissive light guide part penetrating through the interior of a key top so as to face to an illuminating switch, and fixing a rib provided on the outer periphery of the key top in pressure contact to an outer packaging case. SOLUTION: A rubber key top 1 is formed as a structure for compressing a key top outer peripheral rib 1a when fixed to an outer packaging case 5 and an inner structure 6, and since a light guide part 2 is pressed in the rubber key top 1, flooding from the outside is prevented. When pushing the rubber key top 1, a flange part 1b possessed by the rubber key top 1 is deformed, so that the light guide part 2 pushes down an illuminating switch 3. Since the light guide part 2 is molded by hard transparent plastic, a click feeling of the illuminating switch 3 is clearly transmitted. When the illuminating switch 3 emits the light by being pushed, the light guide part 2 guides the light emitted by the illuminating switch 3.

Title: Catv system
Inventor: AOYAMA SHIGEYUKI
IPC: H04J14/00
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent crosstalk by transmitting a down signal through a first electric line, sending it through an electric transmission line to the terminal equipment, distributing/branching an up signal to the second electric connection line and transmitting it through a channel being not used. SOLUTION: An electric signal to be transmitted through an electric transmission line EL to the side of terminal equipment is received through branchers 28 and 30 to respective terminals T1 and T2. Then, the electric signal distributed to the side of second electric connector CL2 by a brancher 26 is converted to an optical signal by an electric/optic converter 24 and that optical signal is propagated through a second optical transmission line OL 1 to the side of center equipment 10. In this case, on the transmission lines OL 1, the signals of even-numbered channels are valid as up signals and the signals of odd- numbered channels can be regarded as the return signals of signals transmitted from the center equipment 10. Since the same frequency band is not shared between up signals and down signals, the radio interference of signals is not generated.

Title: Nmr image diagnosing apparatus
Inventor: NAITOU SEIICHI
IPC: A61B10/00
Filed: 1983-12-29
Abstract: PURPOSE:To enable the diagnosing of a practical NMR image with a high resolution without using any ferromagnetic field by providing a quadratic differential type magnetic flux detection coil for detecting a nuclear magnetic resonator (NMR) and a DC SQUID fluxmeter to which the detection signal is applied from this detection coil. CONSTITUTION:An NMR signal in the direction X from an object is detected with a quadratic differential type magnetic flux coil 4 but the sum of a magnetostatic field and a gradient magnetic field, and an excitation field are not detected because they are in the direction Z and Y respectively. Leakage fluxes from coils 2 for gradient magnetic field has a component in the direction X but can be cancelled therebetween by arranging the quadratic differential type magnetic flux detection coil 4 in the center of the coils 2 for gradient magnetic field. Extraneous noise magnetic fields, line noises and variations in earth magnetism can be cancelled by the quadratic differential balance while being damped by a filter effect with resistance 6 since these are of a low frequency.

Patent JP-H0297841-A (JP)
Title: Air conditioner
Inventor: NUNOKAWA HIROYUKI
IPC: F24F11/02
Filed: 1988-10-03
Abstract: PURPOSE:To improve the efficiency of energy saving by providing a controller which outputs a signal identical to a preset temperature and a room temperature to heat source equipment when a room temperature has reached a specified temperature lower than a preset temperature set by a set point station setter. CONSTITUTION:A microcomputer 6 outputs control signals (OFF signal) to a boiler 7 for 15 seconds every 12 minutes for example when a room temperature TR detected by a room temperature detector 3 has reached a specified temperature lower than a preset temperature, for example, it has exceeded TS-1 deg.C, while a room temperature thermostat 8 outputs OFF signals to the boiler in the case of TS=TR. The boiler 7 drops a set point station setter for a hot water thermostat 9 by 10 deg.C when it receives the OFF signal. This lowers the temperature of hot water running from the boiler 7 to pipes 13 and 14, which makes it possible to inhibit heat radiating loss to a minimum and reduce the supply of fuel to the boiler 7. Furthermore, it is possible to control a cold water supply device so that the cold water temperature may be increased from the point of time when a room temperature has reached a temperature rather higher than a preset temperature in the case of cooling operation.
