Title: Hot water preserver
Inventor: HIGUCHI MITSUHIRO
IPC: F24H9/00
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To save gas rates while keeping the temperature of hot water in bath as high as possible by preventing hot water standing in the bathtub, especially high temperature hot water at the upper part thereof, from being cooled by a gas boiler cooled with outer air before being supplied to the bathtub through a water supply pipe by inter cepting to flow hot water using a valve. SOLUTION: A gas boiler is cooled as the outer air temperature decreases and hot water standing in a bathtub and cooled by the coil gas boiler enters from an upper hot water delivery pipe. It is cooled by the gas boiler to cause cooling effect phenomenon and then passed through a lower water supply pipe into the bathtub. Hot water in the bathtub is thereby cooled through a vicious cycle but a valve blocks entering of cooled hot water into the bathtub through the water supply pipe. Since the water in the gas boiler may freeze to cause damage to the gas boiler if the outer air is cold after the bathtub is drained, water in the gas boiler must be purged by pushing a rod.

Title: Liquid crystal display device and method for driving liquid crystal display element
Inventor: YAMAKAWA EIJI
IPC: G02F1/1347
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display device capable of inexpensively displaying images of multiple gradations by impressing third pulse voltages in synchronization with second pulse voltages on signal electrodes and controlling the pulse width of the third pulse voltages according to the display gradations requested for the pixels to be driven. SOLUTION: The on-timing of the third pulse voltage (the pulse voltage P31 and the pulse voltage P32) to the signal electrodes is delayed by the time ta each meeting the display gradations of the pixels to be driven from the on-timing of the impression of the section pulse voltages (pulse voltage P21 and the pulse voltage P22) to scanning electrodes, by which the pulse width of the third pulse voltages P31, P32 to be impressed to the signal electrodes is changed to the pulse width of the second pulse voltages P21, P22 from zero. As a result, the selection of an intermediate state is made possible over the entire region from the state of the highest reflectivity that the liquid crystal display layer can assume (i.e., a planar state) to the state of the lowest reflectivity (i.e., a focal conic state).
