Title: Pickup speed detector for optical information recording and reproducing device
Inventor: MORI MASASHI
IPC: G11B7/085
Filed: 1989-07-28
Abstract: PURPOSE:To detect the relative moving direction, moving quantity and moving speed of an optical pickup and optical disk by providing a 1st speed calculating circuit which calculates the moving speed of the optical pickup and a 2nd speed calculating circuit which calculates the moving speed from the changing period of an access mark signal. CONSTITUTION:Numerical values are previously laid out to the respective marks of the access mark and the access mark is converted to the numerical value by an access mark detecting circuit 201 at every remodulation of the access mark. The difference between the access mark converted to the numerical value and the access mark previously converted to the numerical value is calculated by a subtracting circuit 204 and is outputted to a moving direction calculating circuit, a moving quantity calculating circuit 209, and the moving speed calculating circuits 206, 208. The values inputted with these circuits are in the proportional relation with the moving quantity of the optical pickup per unit time and, therefore, the speed information and the information on the number of the moving tracks are obtd. by multiplying these numerical values by a constant. The speed detector which detects the relative moving direction, moving quantity and moving speed of the pickup and the optical disk is obtd. in this way.

Title: Misfire discriminating device for engine
Inventor: FURUMURA HIROSHI
IPC: G01M15/04
Filed: 1985-09-02
Abstract: PURPOSE:To discriminate the misfire state with an easy discriminating operation without changing a misfire discrimination level by using a power transducer, an intake air pressure sensor, etc. CONSTITUTION:The intake air pressure detection value of an intake air pressure sensor 3 and the load detection value of a power transducer 4 are read through an A/D converter 14 and are stored temporarily in a RAM 12. The value of intake air pressure corresponding to the load detection value is retrieved from a numerical table stored in a ROM 11. A deviation (e) between the intake air pressure detection value and the retrieved value is calculated and is compared with a certain reference value e0, If it is judged that the deviation (e) exceeds the reference value e0, an accidental fire state variable (j) indicating the duration of the misfire state is counted up. It is discriminated whether the misfire state variable (j) reaches a certain value or not, and a misfire signal is issued from an input/output port 13 if the variable (j) reaches the certain value. Thus, the misfire is discriminated surely by the easy discriminating operation.

Title: Hand tool
Inventor: ANTON NOIMAIYAA
IPC: B25B23/14
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To obtain a hand tool having a clutch which is light-weighted and wears little by forming a clutch element by a ball, and forming the ball on the stop surfaces of a driving pinion and a spindle in such a manner as to link-operate. SOLUTION: Though a spring 4 guides a spindle 5 until it reaches a depth of rotation adjusted by a depth stop, after it reaches the designated depth of rotation, a ball 6 separates from a cavity 7. Accordingly, the relative unrotatable shape lock connection between the spindle 5 and a driving pinion 3 is released. After that, the spring 4 moves a ring 10 to its initial position which is disposed between the ball 6 and the spring 4 and capable of moving in the axial direction of the spindle 5. Thus, the relative axial movement and rotation between the spindle 5 and the driving pinion 3 caused by the link operation between the ball 6 and a groove 8 of the spindle 5 for starting the screw-in work is eliminated.

Title: Flaw detection apparatus for surface flaw
Inventor: MATSUGU TETSUO
IPC: G01N27/83
Filed: 1989-07-26
Abstract: PURPOSE:To certainly detect the accurate position of the flaw of an object to be inspected by moving a line-of-magnetic force density detector arranged to the surface of the object to be inspected or in close vicinity thereto in the right-angle direction to a flaw line and detecting the density of lines of magnetic force. CONSTITUTION:A support member 6 composed of a material having high magnetic permeability is fixed, for example, to the upper surface of the N-pole of a permanent magnet 5 being a line-of-magnetic force source so as to have a bent part 7 and a line-of-magnetic force density detection element 9 is provided to the under surface of the S-pole thereof through a support 8 composed of a non-magnetic body in a state in contact with or in close vicinity to the surface of an object 3 to be inspected and rotated and moved to electrically detect the density of the lines of magnetic force passing through the element 9. When the object 3 to be inspected has no flaw, the density of the lines of magnetic force detected by the detection element is almost uniform at any place of the surface thereof. When a flaw is present, since the ferromagnetic body of the front surface of the object 3 to be inspected is not partially present at the part of the flaw 4, the density of the lines of magnetic force detected by the detection element 9 is reduced and the output of the detection element 9 is reduced. An electronic circuit 2 takes out the electric output of the detection element to detect the position of the flaw.

Title: Video-data compression method
Inventor: JIEEMUZU HEDORII UIRUKINSON
IPC: H04N7/26
Filed: 1994-08-19
Abstract: PURPOSE: To improve the compression degree of data by scanning a sub-band, successively taking out the fixed number of samples which are proportional to a frequency component value inside the sub-band from the sub-band and generating a data stream to be supplied to an entropy encoder. CONSTITUTION: In a repetitive scanning of sub-band data, one sample (first upper left sample) is scanned from the respective sub-bands 0-3, then the four sub-bands are scanned from the sub-bands 4-6 and finally, the 16 pieces of the samples are scanned from the sub-bands 7-9. The number of the samples taken from the respective sub-bands during scanning is proportional to the number of the samples inside the sub-bands. The number of the samples taken out from respective sample bands increases gradually, and space positions inside source video images indicated by the samples correspond. Thus, efficient compression is made possible. The samples are sent via a frame memory to a quantizer.
