Title: Circulating purifier
Inventor: ITO SAKAE
IPC: B01D35/147
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To maintain the purifying capacity of a purifying cartridge over a long period of time without the purifying cartridge clogged by large refuse when a filter detecting means detects the non-loading of a filter by performing control so that a flow passage switching means switches a flow passage to the bypass side. SOLUTION: When a prefilter 23 is removed from a water supply unit 13 in order for a user to clean the prefilter 23 during the purification and thermal insulation of bath water, a CPU outputs a signal to a valve driving circuit so that a switching valve 39 switches a circulating flow passage for bath water to the side of a bypass flow passage 31 by a signal from a filter switching switch 28. When the circulating flow passage is switched to the bypass flow passage 31 side, bath water is sent to a heater 35 without passing through a purifying part 34. And thus even if the device is not stopped on cleaning the prefilter 23, refuse or the like mixed in the bath water in a bathtub 10 is not taken in the purifying part 34 and the bath water can be heated.

Filed: 1990-04-19
Abstract: PURPOSE:To prevent the decrease of printing speed after the change of resolution from happening by equipping a creating means to create a new outline font cache by the current resolution, when the resolution of a cached character is different from the current resolution. CONSTITUTION:When change of an output resolution is indicated, a cache area 5a of a RAM 5 is searched, and a resolution 33 for characters stored in an outline font storage area 30, which have been cached up to that time is compared with a current resolution 43 stored in a current bit map pattern storage area 40, which should be output for printing. When a bit map pattern for the same size characters is not cached in the outline font storage area 30 at the current resolution, the bit map pattern for the same size characters is cached to the outline font storage area 30 newly by the current resolution.

Title: Steering control device
Inventor: SUGITANI NOBUYOSHI
IPC: B62D6/02
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of steering feeling by providing a steering control means with a dead zone, in which steering angle of steering wheel is maintained constant even when the steering angle is changed near a neutral position, and maintaining a range of steering, angle, which forms this dead zone, constant independently of car speed. SOLUTION: A steering shaft 22 is provided with a steering displacement variable sensor 25 for detecting displacement variable of the steering shaft 22, and since the displacement variable of the steering shaft 22 and the steering angle of the steering wheel 21 correspond to each other, steering angle of the steering wheel 21 can be grasped by detecting the displacement variable of the steering shaft 22 with the steering displacement variable sensor 25. At the time of low-speed traveling, the steering wheel 21 is operated to the maximum steering angle with a small handle operated variable, and at the time of high-speed traveling, change of steering of the steering wheel 21 in relation to the handle operated variable is reduced so as to secure the operation stability.  Since a dead zone of the steering angle is maintained constant independently of the car speed V, in the case where transmission ratio is changed in response to the car speed V and where relation of the steering angle to the operation angle is changed, a range of steering angle, which forms the dead zone, is maintained constant.

Title: Heat accumulating device
Inventor: UNO HIROSHI
IPC: F28D20/00
Filed: 1984-05-21
Abstract: PURPOSE:To reduce the width of temperature distribution by a method wherein the filling amount of heat accumulating agent poured into a vessel at the center of a heat accumulating mat is made bigger than the same poured into the vessels at the outer peripheral sections of the mat to prevent the temperature of the central vessel from becoming higher than the temperatures of the peripheral vessels. CONSTITUTION:The heat accumulating device is consisting of a plurality of vessels 3 accommodating the heat accumulating agent, the heat accumulating mat 4 connecting the plurality of vessels 3 and heaters 5 attached to the plurality of vessels 3. The filling amount of heat accumulating agent, poured into the vessels 12 near the central section of the mat, is made bigger than the same poured into the vessels 3 in other sections. The vessel, filled with increased filling amount of heat accumulating agent, requires much amount of heat to rise the temperature thereof and, therefore, the temperature of the vessel is not risen to a temperature higher than the same of the peripheral vessels. On the other hand, the width of temperature distribution may be reduced by this method. In case the vessel 3 having the highest temperature is covered locally by a warm keeping material and the temperature is increased further, the temperature of overcooling preventing material, accommodated in the vessel 3, becomes lower than the temperature of heat resisting life and generation of overcool phenomenon may be prevented without spoiling the function of overcool preventing material.

IPC: F24F13/12
Filed: 1993-04-28
Abstract: PURPOSE:To provide a variable air volume device for air condition which prevents a flow of passing air-conditioning air from being distributed to lower pressure loss for reduction of noise which might be produced owing to the distributed air flow.
