A controller performs, while controlling a first stage cryopanel to have a target temperature: a first determination in which it is determined whether a second stage cryopanel has been heated to a temperature higher than or equal to an alert temperature set to be lower than a maximum temperature of the second stage cryopanel set in the vacuum apparatus; and a second determination in which it is determined whether the second stage cryopanel is continuously being heated, for a preset period of time or longer, to a temperature within a temperature range set on condition that the alert temperature is a maximum. The controller may perform, while controlling the first stage cryopanel to have a target temperature, a third determination in which it is determined whether a state where an error between the temperature of the second stage cryopump during a pumping operation and the minimum attained temperature thereof measured in the initial stage of an operation of the cryopump occurs, has been continued for a continued period of time or longer, the continued period of time being set to be longer than the preset period of time.

Provided are a wind tunnel balance calibrator capable of improving accuracy of attitude control of a wind tunnel balance, and a wind tunnel balance calibrator which can ensure a wide work space around the wind tunnel balance. A wind tunnel balance calibrator includes a load application mechanism for applying a load to a wind tunnel balance and an attitude restoration mechanism for restoring an attitude of the wind tunnel balance. The attitude restoration mechanism is constituted by a parallel-link mechanism including a support plate for supporting the wind tunnel balance, and actuators capable of displacing the attitude of the support plate with six degrees of freedom.

Disclosed is a motor in which a commutator (10) is provided with connecting wires which short-circuit equipotential segments; brushes (21) are constituted by a low-speed brush (21a), a high-speed brush (21b), and a common brush (21c) used in common by the low-speed and high-speed brushes, and are juxtaposed along the circumferential direction. The circumferential brush width (W2) of the high-speed brush is set to be smaller than the circumferential brush width (W1) of the low-speed brush. The high-speed brush and the low-speed brush are formed so that simultaneous sliding contact with equipotential segments (15) can be avoided. Additionally, armature cores (8) are provided such that a plurality of teeth (12) is point-symmetrical about a rotary shaft (3) at equal intervals in the circumferential direction, and the teeth and slots (13) are formed so as to exist alternately at intervals of 90 degrees in the circumferential direction. By virtue of the above configuration, vibration and noise can be reduced while achieving miniaturization and high performance of a motor.

An audio disk/memory disk player. At the time of playing a disk, TOC information in a lead-in area will be read out first after loading of the disk is complete. The player determines whether the disk to be played is an audio disk (CD) or a memory disk (CD-ROM) based on identifying information in the TOC information. If the disk is the memory disk, the operation goes directly to a pause mode so that upon reception of a read command transition to the searching for a designated address is promptly executed to quickly read out the desired data. Only when the disk being played is the audio disk, the audio system is changed to the audio disk from another source, thus permitting a user to view a map while listening to the previous source. When playing for an area having a series of group information recorded is complete in special play mode, the mode is quickly changed to the pause mode in the case of the memory disk to wait for the read command, thus ensuring quick reading of designated map data. If the disk discrimination result indicates the memory disk, a muting process is performed to inhibit a sound generation from a loudspeaker. If in this case there are operation commands originating from erroneous confirmation by the user, at least one of the commands is ignored.

A receiver with automatic tuning function includes: unit for dividing an area where broadcasting stations exist into a plurality of blocks and storing block information relating to the blocks; unit for storing station information relating to each of the broadcasting stations located in the block in association with the block information of the block; unit for storing block information of a current block and blocks surrounding the current block; unit for selecting a broadcasting station out of the plurality of broadcasting stations located in the current block by referring to the station information associated with the block information of the current block; unit for receiving electric wave from the station selected; unit for judging receiving condition of the electric wave and outputting a judgement signal; and unit for renewing the current block.

A voice-operated remote control system which transmits a remote control signal in response to a voice command has a speech recognition circuit for recognizing the voice command. The speech recognition circuit has standard pattern data storage unit for storing a plurality of standard pattern data with respect to each of voice commands. The input voice command is compared with the plural standard pattern data for accurate speech recognition.
摘要:
A disk playing method for a compact disk player or the like in which the time before the start of the playback of designated portion of the disk is reduced. An accumulated total time code is read in the led-in area of the disk, and a predetermined code is detected during this reading operation. If though the predetermined code cannot be detected in reading the accumulated total time code, a frame calculation is carried out to jump the pickup of the disk player across tracks to read another accumulated total time code, whereupon, after the predetermined code has been read, necessary data is read from the lead-in region.
摘要:
A method for operating a disk player in which playing can be continued, even if the selected disk cannot be played for one reason or the other and in with which damage to disks, such as may be caused by vibration in a vehicle-based disk player system, is effectively prevented. When the presence of a magazine set in the disk player is initially detected, trays from the magazine are conveyed one by one to a playing position. When no disk is detected on the trays thus conveyed, the respective magazine is ejected.
摘要:
A disk player particularly useful for vehicles in which a disappearance of a focusing condition during playback is detected. Thereafter, a series of repeated focusing operations of fixed, limited duration are performed until either focusing is achieved or the number of focusing operations reaches a first number. If the preset number is reached, playing ceases. Between the repeated focusing operations, disk instructions may be entered with a restart of the refocusing procedure.

A windshield wiper motor includes a reduction mechanism unit and an electric motor. The electric motor includes a yoke formed in a bottomed cylindrical shape; four magnets arranged in a cylindrical shape on an inner surface of the yoke, an armature including a rotary shaft rotatably supported by the yoke, an armature core fixed to the rotary shaft and including any teeth of fourteen teeth, eighteen teeth, and twenty two teeth, a commutator being fixed to the rotary shaft and including a plurality of segments insulated from each other with the same number as the number of the teeth of the armature core, an armature coil being wound, and a plurality of connecting wires respectively connected to the segments arranged to face each other around the rotary shaft, and a first brush, a second brush, and a third brush coming into sliding contact with the segments of the commutator.
