IPC: G11B19/28
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To enable an optical disk device to perform reproduction in the max. performance at this time. SOLUTION: A rotation control signal is outputted by a drive controller 10 to a spindle motor control part 6 to rotate the spindle motor 2 at the max. revolving speed when an environmental temp. or an output of a power source voltage, etc., is varied, so as to reproduce information at the max. reproducing linear speed capable of reproducing the information under this variable state by the optical disk device. Consequently, the disk 1 is rotated at the max. revolving speed. Then, under this condition, the location of a laser spot formed on the disk 1 is changed in due order, and the max. reproducible area capable of reproducing the information is detected by a signal processing part 9, and hence at least in this max. reproducible area, the disk 1 is rotated at the max. revolving speed to perform reproduction of the information.

Title: Bathtub water purifying apparatus
Inventor: HORIUCHI TOSHIHIRO
IPC: A47K3/00
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To rapidly lower a temperature of bathtub water and to ensure durability by alleviating a stress to the bathtub by operating a heater during a bathing SW turning ON to heat insulate the water to a set temperature, and controlling to switch a water supply valve during bathing SW turning OFF to supply water to the bathtub water. SOLUTION: When bathing is finished so that a bathing SW is turned OFF, a controller 15 stops heat insulating of bathtub water, only circulates the water to continue purifying of the water. When 30 min is elapsed, a drain three-way valve is switched to communicate its connecting port B with its connecting port C, and a circulating three-way valve is switched to communicate its connecting port F with connecting port E. The water is drained out of the apparatus with high energy in a reverse flow form through a filtering tank 5. Thus, dirt stored by the circulation is drained by this operation. Thereafter, a circulation means 7 is stopped, a water supply valve 12 is turned ON, and the water of an amount corresponding to that drained by the reverse washing operation is poured.  In this manner, a temperature of the water is lowered, and hence a stress to the bathtub is alleviated to ensure durability.
