Title: Automatic conveying and inserting apparatus for thin steel plate hoop member
Inventor: EBIHARA KEIICHI
IPC: H01F41/02
Filed: 1986-10-17
Abstract: PURPOSE:To insert a hoop member into a supporting arm by a method wherein the outside diameter, with which the inside diameter can always be maintained constant, of a thin steel plate is automatically computed by measuring the weight of the hoop member of the thin steel plate using a weight measuring instrument, and the center line of the thin steel plate hoop member is moved up to the height which is brought in line with the center line of the supporting arm by the operation of the vertical movement mechanism in accordance with the value obtained as above. CONSTITUTION:The weight of the thin steel plate hoop member 1, mounted on the pedestal of the title apparatus, is measured by a weight measuring instrument 10, and the obtained value is transmitted to the control part 11 having a built-in microcomputer from a control wire 13. The outside diameter, with which the inside diameter of the hoop member 1 can be maintained constant, is computed by the computer in the control part 11, and the height of the position of the center line of a hollow part 1a is computed from said outside diameter. Besides, the difference between said height of position of the center line and the center height of the holding arm 6 of the material feeding device 5 on an automatic thin steel plate processing device is automatically computed. A hydraulic vertical moment mechanism 14 is operated in accordance with said computed value, and the control part 11 gives a travelling and inserting command to the supporting arm 6 of a travelling stand 12 while the hoop member 1 is being lifted to the necessary height.

Title: Thermistor for high temperature
Inventor: KAWAGUCHI YUKIO
IPC: H01C7/04
Filed: 1988-09-29
Abstract: PURPOSE:To improve the adhesiveness between a thermistor substrate and electrode layers by constituting the thermistor substrate of a boron carbide based composite sintered body and the electrode layers by Ni-B plating. CONSTITUTION:A thermistor substrate 2 is produced of a sintered body of Al2O3 and B4C. Then substrate-side electrode layers 3a and 3b of Ni used as a conductive substance are formed on the substrate 2 by an electroplating method. After forming the electrode layers 3a and 3b, electrode layers 4a and 4b for connecting lead wires of Ni-B or Ni-W are formed on the outer surfaces of the layers 3a and 3b. Then a thermistor is obtained by respectively sticking lead terminals 5a and 5b to the layers 4a and 4b and sealing the thermistor substrate 2 with a glass tube 6. Since Ni particles of 2-3mum in particle diameter strongly stick to the B4C, good adhesiveness can be obtained between the substrate-side electrode layers and thermistor substrate. Therefore, a high quality thermistor is obtained, since no exfoliation nor cracking occurs due to thermal stress.

Title: Torque equilibrium apparatus for measuring angle of inclination
Inventor: YAMAGUCHI TAKAO
IPC: G01C9/06
Filed: 1985-11-01
Abstract: PURPOSE:To relieve the impact from the outside, by providing a proportional area having left and right limit points as base points inclusive of left and right ON/OFF boundary areas in light transmission-reception converting characteristics to the variable gap between the surfaces of left and right elements and the reflective surfaces respectively opposed thereto to set the same as the operation area of a feedback current. CONSTITUTION:The max. value of the variable gap between both element surfaces S1, S2 and opposed reflective surfaces is 1mm or less and, eve if there is ON/OFF in the forwardly directing loop Gd in a torque equilibrium block diagram, said loop Gd is regardless of the accuracy of torque equilibrium if a gain is large and this accuracy is entirely determined by a rearwardly directed loop Gf. Actually, in a torque equilibrium angle-of-inclination measuring apparatus using this ON/OFF boundary area, accuracy of + or -1 deg. and an angle of + or -25 deg. are shown at the max. angle of + or -20 deg.. Further, even when impact is applied to the apparatus from the outside, there is no possibility such that a pointer reflective surface is damaged by the attraction or collision with respect to a fixed element surface at all and rather, action relieving impact force is provided. Therefore, it is unnecessary to apply a special protective means for preventing impact to the main body of the apparatus.

Filed: 1990-09-18
Abstract: PURPOSE:To decrease deterioration in the picture by providing a threshold level arithmetic section obtaining a threshold level with respect to the amplitude relating to each frequency component of the picture in the process of picture compression processing from each picture, a threshold level processing section truncating the amplitude smaller than a threshold level obtained by the threshold level arithmetic section and a re- quantization section re-quantizing a frequency data via the threshold level processing section to the device. CONSTITUTION:In the case of implementing picture compression processing, a picture data of an original picture stored in a picture memory is read in matching with block processing by a block processing section 1 and sent to an orthogonal transformation section 2, in which the picture data of the original picture is converted into a frequency data (compression data) for each block in the spatial processing where the energy is concentrated onto a specific frequency for each block. In this case, a threshold level arithmetic section 5 implements the processing that a threshold level with respect to the amplitude is obtained for each picture. Moreover, when a restored picture is obtained from a compressed picture, the picture is processed in the reverse order to the process of the picture compression processing as a coding section 4, a re- quantization processing section 3, a threshold level processing section 6, the orthogonal transformation section 2 and the block processing section 1.

Title: Clock switching circuit
Inventor: KOYAMA YUICHI
IPC: G06F1/06
Filed: 1991-09-26
Abstract: PURPOSE:To perform clock switching free from a momentary break without the occurrence of memory read data error regardless of a phase difference between clocks '0' and '1' to be switched. CONSTITUTION:A switching signal inputted from the external is changed from the low level to the high level at a time t0. This switching signal is inputted to a flip flop 5 and the output of the flip flop 5 is used as a switching control signal 6 of a selector 1, but the switching control signal 6 of the selector 1 is changed by only the fall of the pulse having a width T which is outputted from a monostable multivibrator 2 by an inverter 4; and therefore, the selector 1 is switched at a time t1. Then, the output clock is switched without a momentary break as shown in a figure B, and read data is normally read out from an elastic memory in accordance with counting-up of a read counter.

Title: Magnetron for microwave oven
Inventor: KAWAGUCHI TOSHIO
IPC: H01J23/15
Filed: 1984-11-21
Abstract: PURPOSE:To enable the noise of a magnetron to be greatly inhibited by making the inner surface of an inner strap ring directly face the cathode and the active space and adjusting the inner diameter of the inner strap ring to be smaller than the outer diameters of end hats. CONSTITUTION:Every other vanes 11 are brazed to the inner surface 15a of the inner one 15 of a pair of strap rings in such a manner as to locate the inner surface 15a and the inner end surfaces 11a of the vanes 11 on the same surface. The outer diameters of end hats 17 and 24 are adjusted to be larger than the inner diameter of the inner strap ring 15. Due to the inner strap ring 15, the d.c. electric field and the high-frequency electric field produced near the end of the active space becomes symmetrical relative to the tube axis. Besides, the end hats 17 and 24 which extend up to or outside the inner surface 15a of the inner strap ring 15, reliably intercept electrons traveling along the d.c. magnetic flux toward the pole piece. Consequently, the line noise of the magnetron is greatly reduced.
