A motor-drive circuit includes: an output transistor configured to supply a drive current to a motor for a cooling fan; a switching-control circuit configured to control switching of the output transistor so that the motor rotates in a first direction, or rotates in a second direction opposite to the first direction; and a switching circuit configured to, when a first time has elapsed since start of rotation of the motor in the first direction, cause the switching-control circuit to start switching control so that the motor stops rotating in the first direction and thereafter rotates in the second direction, and configured to, when a second time has elapsed since start of rotation of the motor in the second direction, cause the switching-control circuit to start switching control so that the motor stops rotating in the second direction and thereafter rotates in the first direction.

According to an embodiment, a nuclear reactor containment vessel is provided with a device for holding a molten material of the reactor core and with spacers. The device is installed on the pedestal floor. A holding container which is open upward and a water supply container which is provided below the holding container are provided inside the outer peripheral surface. A water supply flow path extends to the water supply container from the gap between the inner surface of the pedestal side wall and the outer peripheral surface of the device for holding a molten material of the reactor core. The spacers are engaged with the upper end of an outer riser extend between the outside of the outer riser and the inner surface of the pedestal side wall, and prevent the eccentricity of the device.

An information reproducing apparatus reproduces music information with an information reproducing portion. And it refers to an output voice, an output video, a voice level and so on during reproduction of the music information, and specifies a starting time and an ending time of the arbitrary phrase such as a refrain on a touch panel with a reproducing section specifying portion. And it generates a phrase information file indicating the phrase (reproducing section) consisting of the starting time and the ending time of the phrase with a reproducing section information generating portion. In the case where the phrase information file and the music information thereof are extracted to reproduce only a phrase portion or the entire music information, it is also possible to reproduce it by having only a sound quality of the phrase portion changed by a sound quality changing portion.

In a stereo sound digital recording system in which a plurality of tunes or programs are sequentially and digitally recorded on a magnetic tape, the left and right analog input signals are combined and converted to a digital signal. The analog input signals are also applied to a detector which detects the head of the program or tune and which causes to be generated a start identification sub-code signal which is automatically added to the digital signal, before the modulation thereof, and which is recorded on the tape for about nine seconds in the non-sound portion preceding the tune or program. A second sub-code signal, in the form of a program number signal, may also be added to the digital signal, simultaneously with the program start identification sub-code signal, to provide recorded numbers respectively identifying programs which are sequentially recorded on the tape.
摘要:
A signal recording/reproducing apparatus having both bar-type and numeric signal-level displaying units which can be easily read. The apparatus includes a sample-and-hold circuit for sampling and holding an input signal at a first predetermined rate, a first display unit for displaying in bar form the sample values sampled by the sample-and-hold circuit, a data holding circuit for sampling and holding the sample values periodically at a second predetermined rate, and a second display unit for numerically displaying the sample values selected by the data holding circuit. The bar code display can change at a rapid rate to dynamically follow the input signal, while the numeric display changes at a slower rate so as to allow the user sufficient time to comprehend the numerically displayed value.
摘要:
A digital audio player in which the pieces of music are played according to a program. The program is selected so that the total playing time does not exceed a set period of time. The selection is performed by reading playing times from a disk on which are recorded both the pieces of music and their separate playing times.

A core catcher includes a holding surface that catches and holds corium and that introduces a coolant with which surroundings of the core catcher are filled into the core catcher and cool a whole of the core catcher by heat exchange with the introduced coolant. The holding surface and the cooling unit are constructed by arranging blocks which each include a polyhedron having at least one pair of parallel surfaces and having opening portion formed in a surface located in a lateral direction when a first surface that is one of the parallel surfaces is arranged as a bottom surface and are configured such that the polyhedrons communicate with each other via the opening portion when the polyhedrons are arranged adjacent in the lateral direction. The core catcher, as described above, can be achieved easier installation of the blocks without an increase in installation cost.
