Abstract: The present invention aims to prevent a nonrotation state from being brought about even when a drive allowance is changed by variations in a stepping motor or the like. A pulse down counter circuit outputs pulse down control signal for subjecting main drive pulse to control pulse down when time is counted for a predetermined time period. When a detecting signal exceeding a reference threshold voltage detected by a rotation detecting circuit is detected at a first detection section at start of a rotation detecting time period, a control circuit resets the pulse down counter circuit. Thereby, a main drive pulse generating circuit is not subjected to control pulse down by the pulse down counter circuit, and therefore, it is prevented that the main drive pulse is subjected to pulse down unnecessarily.

Abstract: An object of the invention is to make it possible to secure data retained by a cache memory with high reliability without increasing the size or cost of a storage device. When a host-handling processor and a disk processor have recognized occurrence of a power failure, operation of a storage device is continued for about one minute on DC power that is supplied from a battery module. After a lapse of one minute from the occurrence of the power failure, the host-handling processor interrupts the connection between the storage device and a host. Then, the host-handling processor turns off a SW of a host I/F and the disk processor writes, to an HDD, data that have been written to a cache memory. After completion of this processing, the disk processor turns off a SW of the disk I/F and a SW of the HDD. Then, the disk processor causes the battery module to supply DC power only to the cache memory.

Abstract: A watch face uses liquid crystal displays along with a reflective polarizer to produce backgrounds with selective appearances. Therein, the watch employs a polarizer to produce polarized light that is passed downward to a liquid crystal display. The liquid crystal display selectively rotates or does not rotate the polarized light. If the light is rotated, a reflective polarizer layer located beneath the liquid crystal display reflects the rotated light back upward off its surface to provide the watch face with a first color. If the light is not rotated, then the light is transmitted through the reflective polarizer layer to a reflective dial surface disposed beneath. The light is then reflected off the dial surface to provide the watch face with a second color.
