Title: Cleaning cartridge and disk driving device using this cleaning cartridge
Inventor: ISHIKAWA YASUHIKO
IPC: G11B7/121
Filed: 1991-11-13
Abstract: PURPOSE:To prevent deterioration in the optical characteristic of an objective lens by supplying a bias magnetic field from a magnetic head to rotate a permanent magnet and wiping away dust sticking to the surface of the objective lens by the rotation of the cleaning brushes provided at the S pole and N pole of this permanent magnet. CONSTITUTION:A permanent magnet 3 mounted with the cleaning brushes 2 at the S pole and the N pole is supported by a bearing member 5 freely turnably around a revolving shaft 4 in the aperture of the cleaning cartridge 1. The magnet 3 is rotated by the effect of the magnetic field when the bias magnetic field is supplied by the magnetic head 6. The cleaning brushes 2, then, come into contact with the objective lens 7 and wipe away dusts stuck and deposited on the lens 7. The higher effect is obtd. if a cleaner liquid storage tank is provided in the cartridge 1 and the cleaner liquid is supplied to the brushes 2. As a result, the lens 7 is surely cleaned and deterioration in the optical characteristic of the lens 7 is prevented.

Title: Telephone set provided with selective incoming notice function
Inventor: OSAKABE YOSHITAKA
IPC: H04M1/66
Filed: 1985-12-30
Abstract: PURPOSE:To automatically process an incoming call as if the incoming call from an unspecific caller were not in existence by registering a special PB signal, requesting its sending to a caller and informing the incoming call through the bell ringing only when the collation is coincident. CONSTITUTION:When an incoming call to a telephone set takes place, a time limit circuit 10 is operated, the output of the time limit circuit 10 drives a time relay A for a prescribed time and a message is sent to a subscriber line L via selector switches SW0, SWE1 from a message signal generating circuit 6. A calling subscriber replies a message returned from the incoming subscriber and sends its own subscriber number in the form of PB signal. A central processing unit CPU reads one or plural specific subscriber numbers registered in advance from a memory section 3 and starts a drive circuit 4 when the collation with a received caller subscriber number is coincident to ring a bell thereby informing the incoming call. In case of dissident, no drive circuit 4 is driven and no bell ring incoming notice is executed.

IPC: G05D1/02
Filed: 1985-12-31
Abstract: PURPOSE:To smoothly move an unmanned conveying vehicle by increasing a current flowing to a motor when judging that the vehicle is in a stopped state. CONSTITUTION:A speed controller 3 compares a speed command 1 with the output of an encoder 9 and outputs a current command. A current controller 5 compares the current command with a current signal detected by a current detector 8, and applies a control signal to a converter 6. A vehicle stop detector 10 calculates the output of the encoder 9, and when the detector 10 detects the stop of the vehicle, it outputs a motor current rise command to a comparator 4. Thus, it can prevent the vehicle from stopping in a recessed terrain or a slope and can travel the vehicle smoothly on a flat road.

Title: Multichannel recording
Inventor: NIWA NAOMASA
IPC: G01D9/32
Filed: 1988-11-26
Abstract: PURPOSE:To enable a simultaneous recording with an easier viewing of multiple outputs by recording a vertical line with a length thereof corresponding to a peak level of measured outputs in a plurality of channels at a position on a record of the peak. CONSTITUTION:A sampling circuit 1 is controlled with a controller CPU and an operation of sampling outputs of channel detectors C1-Cn is repeated at a fixed cycle. Then, a memory 2 stores the outputs of the detectors C1-Cn thus sampled into areas of the respective channels. Then, upon the end of loading of data in the channels at the first measurement, the CPU performs a data processing. Then, a printer 3 is controlled to shift a zero-point level in the channels in a Y axis to record peaks in the channels at corresponding positions of the peaks as vertical line with a length thereof corresponding to peak levels thereof. This eliminates a ruggedness of a base line, a recording of a peak profile and overlapping of records between adjacent channels, thereby enabling the obtaining of an easy to view record.
