Title: Cpu resource averaging system
Inventor: MATSUMOTO HIDEO
IPC: G06F9/46
Filed: 1988-04-13
Abstract: PURPOSE:To prevent a CPU resource from being occupied by a specific job by controlling a CPU dispatch to jobs based upon information obtained from a CPU dispatch frequency control means. CONSTITUTION:A job group name defining means 2 defines a job group name including a job 1 at the time of starting the execution of the job 1 and the defined job group name is stored by a job group name storing means 4.

A CPU dispatch control means 3 controls CPU dispatch to the job 1 based upon the information of the means 5. Since the CPU dispatch frequency corresponding to each job group is suppressed lower than the fixed frequency in addition to a basic traveling condition, the CPU resource can be prevented from being occupied by a specific job.

Title: Cassette tape player
Inventor: OTSUKI AKIRA
IPC: G11B15/675
Filed: 1995-04-17
Abstract: PURPOSE: To obtain a cassette tape player with which the gentle driving of a cassette transfer mechanism and a mode selection lever is possible and the miniaturization of a driving mechanism is possible. CONSTITUTION: The movement of a mode selection lever 65 is prohibited by a locking lever 63, by which the revolution of this sub-motor 3 is outputted from a carrier at the time of loading or ejection operation of a tape cassette.

The revolution of the sub-motor 3 is outputted from a ring gear and a second rack 65a meshed with the external tooth part of this ring gear is driven, by which the locking lever 63 is turned at the time of mode selection, such as FF and reproduction. Consequently, the movement of the block body having the first rack is prohibited by the locking lever 63 and the mode selection lever 65 is moved to a desired operation mode position by the revolution of the sub-motor 3.

Title: Contact type image sensor
Inventor: KITAMURA KOICHI
IPC: H04N5/335
Filed: 1990-04-05
Abstract: PURPOSE:To rapidly drive the contact type image sensor and to prevent the generation of cross talking at a cross-over part by controlling the sensor so that potential differences between the cathods of plural photodiodes or between their anodes are always held at zero volt. CONSTITUTION:At the time of reading out information stored in the photodiodes 6, a control drive part 10 applies a -5V pulse e.g. to blocking diodes 5, and at the time of storing the information, controls the cathode sides of the diodes 5 to '0... volt. A control part 20 always holds the cathode sides of the photodiodes 6 at '0' volt. Since the potential difference is not generated between the electrodes on the cross-over part of the photodiodes 6 even when electrostatic capacity exists, the floating capacity of the cross-over part does not exert influence upon the operation of the circuit. Consequently, rapid drive can be attained and the generation of cross talking on the cross-over part can be prevented.

Title: Dust sensor for vacuum cleaner
Inventor: OKAUCHI TERUO
IPC: A47L9/28
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a low-priced and highly sensitive dust sensor that fully unnecessary to align each of the optic axes of a floodlight and an optical receiver, that does not require great precision in material processing and assembling, and that stably obtains constant sensitivity in dust detection, not relying on a product. SOLUTION: A floodlight 2 illuminates the inside of pipe 1 for dust suction in a vacuum cleaner, while an optical receiver 3 detects brightness inside the pipe 1, which is illuminated with the floodlight 2. The floodlight 2 and the optical receiver 3 are arranged on an even part parallel to a central axis in the longitudinal direction of the pipe 1, as the floodlight 2 and the optical receiver 3 are separated a little and are parallel to each optic axis. As dust 10a, 10b pass through the pipe 1, a beam of light from the floodlight 2 is blocked off by the dust 10a and is reflected diffusely by the dust 10b. Because of this, the brightness of relevant part inside the pipe 1 relatively declines or rises, and an output value of the optical receiver 3 also decreases or increases. Therefore, the presence of dust is detected by detecting a change in the increase or decrease of this output value.

Title: Information quantity expansion system for communication protocol
Inventor: SAITO KATSUMI
IPC: H04L29/08
Filed: 1990-04-06
Abstract: PURPOSE:To avoid an upper limit of information quantity able to be sent in one sequence by sending/receiving a command RIM and a command SIM every time seven information sets per frame are sent and setting a transmission sequence number and a reception sequence number to 0 so as to send remaining information. CONSTITUTION:Let N(S),N(R) be 3 bits each and a limit to one information part be 32 bytes, then the information quantity of a secondary station is 7 I frames. The secondary station sends 7 l frames to await RR(*1) from a primary station. The secondary station confirms it from N(R)=7 that the primary station receives 7 I frames and sends a command RIM. Then the primary station sends a command SIM. Through the transmission and reception as above, N(S),N(R) are set 0 to both the primary station and the secondary station, and the secondary station sends the remaining information. Thus, the primary station receives information of eight I frames from the secondary station.
