Patent JP-S5759105-A (JP)
Title: Contact detector
Inventor: NISHIMURA HIDEO
IPC: G01B7/00
Filed: 1980-09-26
Abstract: PURPOSE:To achieve high-sensitivity detection without using a high-frequency power source by providing an annular energizing coil which surrounds an induced current path and generates magnetic flux and a detection coil which surrounds the induced current path. CONSTITUTION:In a machine tool, for example, a troidal coil 20 surrounding a spindle 12 connects with an AC power source 21. When a tool T and a workpiece W come into contact with each other, an induced current flows through a current path 23 including the tool T, the spindle 12, a main shaft head 11, a brush 16, a working machine body 10, a table 15, and the workpiece W. Its induction magnetic field permits an alternating current to flow to a detection coil 22, which sends an AC voltage signal to a discriminating circuit 25. The energizing coil 20 and detection coil 22 are insulated magnetically by a shield part 24. Consequently, the contact between the tool T and the workpiece W is detected with high sensitivity without using a high-frequency power source.

Title: Dynamic image encoding method and device therefor
Inventor: HANAMURA TAKESHI
IPC: H04N19/423
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To improve the encoding processing speed of dynamic images by selecting the respective optimum images for plural types of estimated images and encoding each of the images which form digital dynamic images. SOLUTION: A common block decision part 230 decides whether the number of columns and rows of the smallest block set in a reference image are smaller than the largest number of columns and rows which are set by a setting part 220, based on plural detected dynamic vectors for each of similar blocks set in the reference image of the same frame. If the number of columns and rows in the smallest block are smaller than the largest number of set columns and rows, an estimated image to be generated by an estimated image generation part 240 is decided and also the smallest block is read out for generating the frame and field estimated images. Then the estimating horizontal interpolation images are generated, in response to the frame block and top/bottom field blocks of the present image.  In addition, when one or more dynamic vector horizontal elements have accuracy of half pixel among those frame and top/bottom field dynamic vectors, a horizontal interpolated image is generates for the smallest block, including its similar block and a horizontal interpolated image of a dynamic vector is extracted. Thus, the computing frequency of interpolation can be reduced.

Filed: 1988-06-01
Abstract: PURPOSE:To make accurate measurement with the title instrument by providing a heat shielding device composed of plural perforated plates between an acoustic wave transmitter and receiver provided on a wall and a high-temperature fluid. CONSTITUTION:A heat shielding plate 12 composed of ceramic perforated plates is provided on the furnace center side of an acoustic wave sensor.

Then similar operations are performed on the receiving side also and the propagating time tB is measured. Thereafter, the propagating time (t) of the acoustic waves transmitted from the transmitting side and received on the receiving side is measured. From the operation the in-furnace propagating time is corrected to t-(tA+tB)/2. Thus accurate measurement can be performed.

Title: Underwater depth multiple-stage acoustic measurement buoy
Inventor: TSUBOTA KOTARO
IPC: B63B22/00
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To reduce the size and costs and improve environmental performance and to detect the depth with a small-scale circuit by transmitting signals by changing frequency according to a cut part. SOLUTION: When a measurement buoy is thrown onto the surface of the sea, a suspension cable 3 is delivered from a cable pack 8 and is suspended at an underwater part 2. The suspension of the underwater part 2 stopped by the connection of a depth-switching mechanism 5 at the location of a tap 6 closest to a floating part 1 among a tap group 7 being located halfway to the suspension cable 3. An acoustic measurement is made at the depth by a sensor part 9, and the measurement information is transmitted from a transmitter 13 and a transmission antenna 14 via the suspension cable 3. A control signal for switching the depth being transmitted by radio is received by a reception antenna 16 and a receiver 15 and is transmitted to a control circuit 12 via the suspension cable 3 for switching the depth.  Since a signal at the same frequency band as the sensor information is transmitted while the depth is switched, it can be confirmed which tap has been cut and to what depth a buoy has sunk by confirming the frequency.
