Inventor: MIZOGUCHI TADAO
IPC: G06F11/10
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To avoid an inaccurate CRC(cyclic redundancy check) arithmetic operation when the processing data are intermittently transferred and to secure an accurate CRC arithmetic operation by saving the processed bit data, deciding an empty state of a FIFO memory to notify a CRC arithmetic execution part of this state and interrupting the CRC arithmetic operation via the CRC arithmetic execution part that received the notification indicating the empty state of the FIFO memory. SOLUTION: In a CRC arithmetic operation mode, an arithmetic result register 108 is initialized in response to a generator polynomial and the value of the initialized register 108 and the serial data received from a parallel/serial conversion part 105 undergo a division via a division part 107. Then the result of this division is inputted again to the register 108. When the processing data are emptied out of a FIFO memory 102, an empty signal is inputted to an arithmetic interruption recognition part 110. Thus, the part 110 produces an arithmetic interruption signal and transmits it to a CRC arithmetic execution part 104. The part 104 interrupts the CRC arithmetic operation. Thus, it's possible to avoid the generation of an inaccurate CRC arithmetic result.

Filed: 1988-11-02
Abstract: PURPOSE:To measure the amount of soil with good accuracy by calculating the sectional area through image processing of a picked-up outline, multiplying said sectional area by a speed thereby to obtain the volume per unit time, and sequentially aggregating the volumes. CONSTITUTION:A video sensor 6 obtains monochromatic binary signals through an image processing function on the basis of an outline of soil and sands picked up by a video camera 2. The video sensor 6 determines an area occupied by a window W determined by a CRT display 7 as the position of the section where the soil and sands are optically cut. The video sensor 6 outputs the shadowed area in a fan shape as the monochromatic area with the area of the shielding plate 3 and a conveyor 1 removed. The processed signal from the video sensor 6 is, together with vertical and horizontal synchronizing signals, displayed on the display 7. At the same time, dots are counted by a counter 8, which is then input to a computer 9. The computer 9 takes in an output signal of a speed sensor 5, and operates total volume of soil based on the speed signal and the count of dots. The result is displayed on the display 7 and recorded by a printer 10.

Title: Seat for vehicle
Inventor: MIKAMI TATSUYA
IPC: B60R21/02
Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent an upper body from falling forward by providing an engaging claw fitted to a leg part and engaged with the rear end part of a seat part, or a compression coil spring fitted to the back face of the front half part of the seat part and upward energizing it, and instantaneously moving the seat part to a fixed position at receiving a shock. SOLUTION: When a shock from the front part is detected with a sensor, or when the push button of a driver's seat or the like is pushed, an electromagnet 12 as a seat rear end part engagement releasing means 32 is excited, and hence the engaging claw 7 is moved against the frontward energizing force of a compression coil spring 11, so as to release engagement with an engaging groove 10. Further, when the engagement is not released and impulsive force is applied, a supporting shaft 4 fitted to the seat part 2 is advanced in a supporting shaft sliding bearing 5 against the rearward energizing force of a compression coil spring 6 by inertia force, so as to release engagement with the engaging groove 10.  As a result, the seat part 2 on the normal position is moved, the seat part 2' on the fixed tilt position is absorbed by a buffer 8 interposed between a leg part 1 and itself, and hence an upper body is obstructed to deviate from the seat part 2'.

Title: Dielectric thin-film and ceramic capacitor
Inventor: KAMIGAKI YASUYO
IPC: H01G4/12
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a dielectrics thin-film and a ceramic capacitor which does not contain lead with high dielectric-constant, low loss, small fluctuation in electrostatic capacity under temperature change, while manufactured at low temperature with high dielectric-constant even in a high-frequency region. SOLUTION: The dielectrics thin-film comprises a tungsten bronze type composite oxide comprising, as a metal element, K, Sr, Ca, and Nb, and satisfies 0<x<=0.25, while a composition formula of mole ratio of metal element oxide is represented by K (Sr1-x Cax)2 Nb5 O15. Here, x which represents Ca amount is 0.25 or less because, if x is more than 0.25, the dielectric constant at room temperature abruptly drops and a film becomes porous. The x is preferred at 0.05<=x<=0.20 for a dielectric constant to be improved.

Title: Magnetic recording and reproducing device
Inventor: SUGIMACHI KAZUNORI
IPC: H04N5/783
Filed: 1984-12-28
Abstract: PURPOSE:To obtain a slow-speed faceplate, motion of which is smooth, by servo-locking a tape at a slow speed, by making its tape move continuously and by regenerating the same track with the same azimuth angle's head as many as a number of times depending upon the above slow speed. CONSTITUTION:When reproduced with a 1/3 slow mode, a CTL pulse from a CTL head 33 and a rotation detector of capstan motor as well as a FG pulse from a FG37 are inputted to a servo IC35 through amplifiers 34 and 38. The servo IC35 is multiplied by a multiplier three times and a capstan servo system is locked at a 1/3 speed of normal time and at a phase. Being delayed to the CTL pulse by a mono-multi vibrator, a signal passing through a differentiating circuit and buffer circuit resets flip-flops 20 and 21. And since a head using always for the reproduction makes a reproducing track have the same azimuth angle, it goes to be a field slow. Thus none of a noise occurs and such a head makes it possible to carry out a stable reproduction having a smooth motion.
