Title: Steam trap
Inventor: FUJIWARA KATSUJI
IPC: F16T1/30
Filed: 1980-11-27
Abstract: PURPOSE:To enhance the erosion resistance of a steam trap by a method wherein a sacrificial anode is disposed at a ceiling part of a valve chamber or other similar part where steam is stagnated so that the steam is condensed on the surface of the sacrificial anode. CONSTITUTION:The sacrificial anode plate 32 of a metallic material baser than the metal constituting the trap is provided at the ceiling part of the valve chamber 4 where steam is stagnated. As a result, the anode plate 32 causes an anti- corrosive current to flow against a corrosive current, thereby preventing chemical corrosion and erosion. In addition, even when oxide films on the surfaces of a contacting member 20 of a valve seat, a cylindrical part at the tip of a main body member 19 and the internal wall of a bush 24 are peeled off by the contacting force of a float 25 and the friction force of a fluid with the result that internal metallic layers are exposed, the metal dissolved from the anode plate 32 is deposited on the exposed layers to form a protective film. Accordingly, the contacting member 20 of the valve seat exhibits the abrasion resistance of a hard metal, while the protective films on the surfaces of other parts are retained and erosion resistance is enhanced.

Abstract: PURPOSE:To obtain a liquid crystal display element of a sharp black and white display by providing a pair of polarizing plates to the outside of a cell formed by sandwiching a liquid crystal between a pair of transparent electrode substrates and providing liquid crystal layers which have the same twist angle and are reverse in spiral direction between one electrode and polarizing plates. CONSTITUTION:A pair of the polarizing plates are provided on the outside of the liquid crystal cell disposed to have 200-300 deg. twist angles between both electrodes at the time of impressing no voltage to the cell. The liquid crystal layers which have the same twist angle and are reverse in the spiral direction are disposed between the one electrode and the polarizing plates in such a manner that the molecular axis of the parts brought into contact with each other by holding the electrodes inbetween intersect nearly orthogonally with each other. The two liquid crystal layers are used but electrodes are not required for the 2nd liquid crystal layer. The layer thickness of both is set the same and the product DELTAn.d of the double refractive index DELTAn and the layer thickness d is set in a 0.5-2.0mum range. A pair of the polarizing plates are so disposed that the axes of polarization thereof intersect nearly orthogonally with each other. The colorful display is thus made by using filters together with the black and white display.

Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To enable to supply and drain water without inconvenience, by equipping a water supply stopping means to stop water supply to a sub-washing tub when a water supply timer means counted a preset time longer than a prescribed time. SOLUTION: This washing machine is equipped with a first water supply passage to a main washing tub and a second water supply passage to a sub- washing tub which are branched from a common water supply passage and a water supply timer means (S2) to count the water supply time from the second water supply passage to the sub-washing tub. When water is fed to the sub- washing tub, whether water is fed to the main washing tub (outer tub) or not is judged (S3), and if water supply is not performed, the water supply timer means (S2) stops water supply to the sub-washing tub when it counted a preset time. If water supply is performed, water supply to the sub-washing tub is stopped (S5) when the water supply timer means (S2) counted time longer than the preset time by a prescribed time. Thus water supply to the sub-washing tub can be suitably performed.

Title: Method of driving charge transfer device
Inventor: ITO HIROAKI
IPC: H01L21/339
Filed: 1987-07-08
Abstract: PURPOSE:To improve charge detecting sensitivity without reducing the driving frequency by a method wherein the quantity of charge per unit area accumulated in the first transfer electrode is made larger than that accumulated the other transfer electrodes by making the potential to be supplied to the first transfer electrode larger than that which is supplied to other transfer electrodes. CONSTITUTION:The transfer electrode 12, which is directly positioned in front of an output gate electrode 13, is wired separately from phi1 electrodes 3, 4, 7, 8 and 11 on which voltage is applied in synchronization with the electrode 12. When the amplitude V1B of phi1H application voltage of the transfer electrode 12 is made larger than the amplitude V1 of application voltage phi1, the difference DELTAphi1 of the potential to be formed under the electrodes 11 and 12 becomes larger than the potential difference DELTAphi of the ordinary voltage amplitude V1. As a result, the transfer channel can be narrowed without lengthening the transfer charge 12a located directly in front of an output gate 13 while the quantity of transfer charge is being maintained, and the sensitivity of the charge detecting device can also be increased.

Abstract: PURPOSE:To prevent a reversal development due to the voltage applied to a picture element where the display state at the write time should be held, by specifying relations among the resistance value and the capacity of a ferroelectric liquid crystal layer, the capacity of a dielectric layer, and the pulse width of the driving voltage applied to the picture element. CONSTITUTION:A pulse width DELTAT(sec) of the driving voltage applied to the picture element is set in accordance with a formula 1 where R (OMEGA) is the resistance value of the ferroelectric liquid crystal layer, C1 (F) is the capacity of this layer per picture element and C2 (F) is the capacity of the dielectric layer per picture element. In the formula 1, (a) is a constant satisfying a formula 2 and Vth is the threshold voltage (V) of the ferroelectric liquid crystal and VON is the voltage value (V) for write. (b) is a constant given by formula 3, and V1 is the inversion start voltage (V). Thus, the write state is held in the one-frame period though a reverse electric field (-DELTAV0) due to discharging from the capacity of the dielectric layer which is caused for switching between pulses having opposite polarities exists in accordance with application of the line sequential write system, and a prescribed display is attained.
