Title: Bathtub
Inventor: NAITO SUSUMU
IPC: A47K3/00
Filed: 1987-12-16
Abstract: PURPOSE: To intend to purify warm water in the bathtub and to protect the dirts from sticking to it due to positioning a waterline inside the bathtub by making the warm water overflow from a periphery part to circulate it. CONSTITUTION: Before bathing, warm water is stored in a bathtub 1 in a state overflowing from its opening 11, electricity is turned off with an operation switch. When going out from the bathtub 1 after sinking a human body, water level falls down. This is detected by a water level switch S to drive a pump P, and washed water stored in an overflow room 10 is supplied into the bathtub 1. When reaching an overflowing water level from the opening 11, the water level switch S is changed its constant point, but the pump P continues its operation for a setting time of a timer. In a connected tube 12 a filter F is mounted to purify the circulated warm water.

Title: Gas boiler and control for gas supply for gas boiler
Inventor: KIN JIKAN
IPC: F23N1/08
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To reduce noise generated owing to a maximum gas supply pressure during the initial time of operation and the operation of a gas boiler. SOLUTION: Gas is supplied to a gas burner under a gas supply pressure not lower than an ignition pressure to ignite gas and the gas supply pressure is increased for a prescribed time until the temperature of a fluid to be heated reaches a prescribed setting temperature. The gas supply pressure is increased stepwise depending on prescribed number of pressure levels obtained by partitioning a range from the ignition pressure to the maximum gas supply pressure of a gas boiler. When the temperature of the fluid to be heated reaches the setting temperature, the gas is supplied under a gas supply pressure calculated in accordance with a proportional control system.  Thus, since a gas supply time based on the maximum gas supply pressure depending on the change in the setting temperature during the initial operation or the operation of the gas boiler is shortened, noise due to combustion generated during the operation of the gas boiler is reduced.

Title: Picture density conversion system
Inventor: TAISE AZUSA
IPC: H04N1/387
Filed: 1987-12-19
Abstract: PURPOSE:To accurately and highly speedily realize the mutual conversion of densities having different systems of units respectively by passing through a simple fixed density converting means obedient to a conversion ratio with the minimum error. CONSTITUTION:The density conversion between a device group 10 of a multimeter-system and a device group 11 of an inch-system always selects a conversion pass 12 obedient to the conversion ratio with the minimum error, for example, the conversion ratio between 8.7dot/mm and 240dpi, and all the other density conversions pass through the conversion pass 12. Namely, the mutual density conversion in devices A1 and A2 of the multimeter-system obeys a direct conversion through a conversion pass 100, in the same manner, the mutual density conversion in devices B1-B3 of the inch-system obeys the direct conversion through direct passes 110-112, and the conversion between the devices A1 and A2 of the multimeter-system and the devices B1, B2, and B3 of the inch-system always passes through the pass 12 for the density conversion with the minimum error. Thus, the propagation of the error due to a round- about carrying can be eliminated, and an accurate density conversion can be realized.

Title: Fuel battery
Inventor: SAKAKIBARA YASUYUKI
IPC: H01M8/24
Filed: 1988-12-21
Abstract: PURPOSE:To enhance the efficiency of a fuel battery by providing a water absorptive layer consisting of a hydrophile material on the surface of a groove for supply of oxidating agent in such an arrangement as along the longitudinal of this groove, and at its end face, providing a water gathering member consisting of hydrophile material equipped with a passage or circulation of the oxidating agent. CONSTITUTION:When a fuel battery is driven, water is produced at an air electrode as a result of reaction. This water becomes drops in a groove 11 provided in a separator 10, wherein it is absorbed immediately in a water absorptive layer because it exists on the surface of the groove 11, so that it is prevented that the large particles generated from the water from choking the groove. The water absorbed in this water absorptive layer 13 is carried to the end of the separator by 10 by means of capillary phenomenon. Because this water absorptive layer 13 is in contact with a water collecting member 15, the water is transferred to the member 15 to move downward by its own weight and by capillary phenomenon to then be exhausted to outside the system from a drain 31. Because the water produced at the air electrode does not stagnate in oxidating agent supplying groove but is exhausted quickly, the performance of the battery as a fuel battery will not drop with the initial performance well maintained for a long period of time.

Filed: 1987-12-18
Abstract: PURPOSE:To detect abnormality in a short pulse width unable to be detected, by lengthening input signal with an unidentifiable pulse width within a range not exceeding a reference pulse width for error discrimination to discriminate the sum of the signal involved and an input signals with a pulse width error discriminator circuit. CONSTITUTION:When an input signal (a) with an abnormality short pulse width of 5ns or so is inputted, a pulse width assuring circuit 18 outputs a pulse width assurance signal (c) with a pulse width T1 based on a differentiation signal (d) of a first differentiation circuit 16 and a second differentiation circuit 20 outputs a differentiation signal (d) with a pulse width T2. The differentiation signal (d) is added to the input signal with an OR gate 12 and the results are outputted to an error discriminator circuit 14 through an NAND gate 28. At this point, as a port output signal (e) is smaller than a reference pulse width Tref for error discrimination, an error detection output of the pulse width is generated.

Title: Control of road heating
Inventor: WATABE TAKAAKI
IPC: E01C11/26
Filed: 1989-12-12
Abstract: PURPOSE:To make accurate control of road surface temperature available in any road surface condition by detecting the conditions of the road surface with two resistance detecting elements, one of which is electrified by an electric heater provided to an insulating body between paired members, and by controlling supply of electric power with set points for the road surface temperature that are made by the above-mentioned detections. CONSTITUTION:A road surface condition-detecting sensor 3 connected to a controller 1 that controls supply of electric power to a road heating system is composed of two resistance- detecting elements 3a and 3b, and an electric heater 34 placed in an insulating body 33b between paired members is electrified for heating. In the case where the road surface is in dry condition, the resistance between the electrodes is almost infinite, and in the case where the road surface is in wet condition, the resistance becomes low as the space between the electrodes is kept conductive. In the case where ice and snow exist on the road surface, the resistance becomes low in the detecting element 3b with snow-melting made on the surface of the electrode, while the resistance in the detecting element 3a becomes higher than that in the detecting element 3b because of snow. Data collected from such road surface conditions are made available for determination of set points for the road surface temperature. Supply of electric power is then controlled with actual values measured with a road surface temperature-measuring means 2 compared with the above-mentioned set points.
