Title: Hot-water supply equipment with heat-retaining function
Inventor: SATO YASUHIKO
IPC: F24H1/10
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To consider durability and maintain heat-retaining performance, by providing a control part for allowing a remaining water temperature sensor to set fire when temperature goes below a heat-retaining combustion starting temperature, for stopping heat-retaining combustion when temperature goes above it, and for decreasing the heat-retaining combustion starting temperature according to the number of ignition. SOLUTION: When a heat-retaining switch of remote controller of hot-water supply equipment is turned on, a heat-retaining function is operated after the supply of hot water is stopped, and hot water in a heat exchanger 3 is heated and the heat is retained by igniting a burner 1 intermittently, thus preventing temperature of the hot water from decreasing. Only a hot-water supply capacity switching solenoid valve 7 is opened to prevent hot water from boiling for burning with the minimum unit hot-water supply capacity. One combustion time is also set to a relatively short time. With an ignition interval, for example the temperature of remaining water in the hot-water supply equipment is detected by a temperature sensor and is variable depending on the difference to a setting temperature.  An instant hot-water function may achieve operation at an arbitrary time zone set by a user or may automatically stop the instant hot-water function, even if an instant hot-water switch is not turned off when no hot-water equipment is used continuously for a fixed amount of time.

Title: Liquid crystal display device and its production
Inventor: INOUE HIROYASU
IPC: G02F1/139
Filed: 1999-12-28
Abstract: PROBLEM TO BE SOLVED: To prevent a region having alignment defects from appearing in a display part and to obtain a bright and good display without decrease in the luminance by forming a linear protruding structure on a substrate and forming a subprotruding structure with its width larger than the width of the main protruding structure. SOLUTION: Protrusions 20 as the structure to control the alignment of a liquid crystal on the CF substrate side are formed oblique to the pixels to control the alignment of the liquid crystal with slits 18 formed in a TFT substrate. The slits 18 and the protrusions 20 are alternately arranged in a two-dimensional view. The subprotrusion 20a is formed as extended from the protrusion 20 and along the edge of the pixel electrode 16. The subprotrusion 20a is formed as extended from the protrusion 20 in the crossing part of the protrusion 20 and the edge of the pixel electrode 16 in the two-dimensional view in the side where the protrusion 20 and the pixel electrode 20a make an obtuse angle. In this method, the width of the subprotrusion 20a is made larger than the width of the protrusion 20.  Therefore, concentration of lines of electric force to the corner of a color resin can be avoided, and the region having alignment defects is prevented from appearing in the display part.

Title: Liquid mass recovering method and liquid mass recovery device
Inventor: KOMATSU MASAHIRO
IPC: B01D17/00
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To easily heat and recover liquid mass by supplying a high frequency current to a working coil placed on a liquid mass contact member, to make the liquid mass contact member itself generate heat by induction heating, thereby lowering the viscosity of liquid mass to recover it through a recovery pipe. SOLUTION: When a high frequency current is supplied to a mat-like working coil 2 from a high frequency inverter unit 3, an inner bottom plate 7 (liquid mass contact member) which is a conductive, magnetic substance, itself generates heat by induction heating. When a steel plate constituting a tank 6 thus generates heat itself, heavy oil inside can be efficiently heated compared with the case of being heated from the outside, and the temperature of heavy oil can rise even in severe cold, and viscosity is lowered to change heavy oil into an easy-to-flow state. Since a mat-like case of the mat-like working coil 2 has heat insulating properties, heat reserving effect of the heating inner bottom plate 7 can be expected to heighten temperature rise efficiency.
