Inventor: KATOU YUUJI
IPC: G01S13/50
Filed: 1980-04-14
Abstract: PURPOSE:To perform doppler detection precisely in the case when a receiving signal is discontinued, by outputting the sine wave frequency which is in the immediately previous state. CONSTITUTION:When the receiving signal is normal, a multiplexer 16 is operated by the output of a coincidence detecting circuit 11, the counted value of a difference signal counter 15 is transferred to a register 17. The output signal of said register 17 is converted to an analog signal by an A/D converter 18. Said analog single is supplied to a voltage control oscillator 19. The difference output signal in frequencies which are proportional to the voltages of analog output signal is obtained. When the receiving signal is discontinued, the difference signal is also discontinued, the state of a gate counter 9 and the state of a gate counter 10 are not coincided, and the multiplexer 16 does not operate. Therefore, the contents of the register 17 are held at the immediately previous state before discontinuance, and the output of the voltage control oscillator 19 remains at the frequency immediately before the receiving signal is discontinued.

IPC: G01R33/035
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To measure feeble magnetism in a number of directions with a simple structure. SOLUTION: In an extremely low temperature tank CR are arranged 256 measuring sensors Csi in various directions. Mutually orthogonal x-axial reference sensor Crx, y-axial reference sensor Cry, and z-axial reference sensor Crz are also arranged in the extremely low temperature tank CR. Each output of nx, ny, nz of the x-axial reference sensor Crx, y-axial reference sensor Cry, and z-axial reference sensor Crz is load-added by multipliers Mxi, Myi, Mzi, an adder Ai, and a subtracted Bi to compose each reference output ni corresponding to the direction of each measuring sensor Csi. The reference output ni corresponding to one direction is subtracted from the output qi of the measuring sensor Ci of each direction to provide an output si showing the feeble magnetism in this direction.  A factor optimizing part KO regularly or periodically optimizes the weighting factors αi, βi, γi of load addition. Thus, feeble magnetism in a number of directions can be measured, the structure is simplified, and the handling is facilitated.

Title: Mig circumferential welding method
Inventor: TANAKA KAZUO
IPC: B23K9/173
Filed: 1987-03-05
Abstract: PURPOSE:To improve product yield by dividing the welding stage into the starting stage for the specific time and the stationary stage and making an arc starting current under specific times as low as a stationary current and setting the arc current of a starting stage period low as compared with the stationary current. CONSTITUTION:The arc welding stage is divided into the starting stage extending for >=0.5sec from the starting time (to) and the subsequent stationary stage. The arc starting current Is of MIG welding of the starting stage is controlled to <=0.8 times as low as the stationary arc current Ic of the stationary stage and further, a welding current during the starting stage is changed with a shape of a curve of I, II or III and always set low as compared with the stationary current Ic. At this time, since a bead of a welding starting part is small, when a new bead overlaps with the bead of the starting part, most of the lower bead is remolten and a blowhole is floated and eliminated. By this method, since the occurrence of weld defects is reduced, the product yield is improved.

Filed: 1979-04-23
Abstract: PURPOSE:To improve the latch-up strength of a complementary MIS semiconductor device and the reliability thereof by forming the diffusion depth of a guard band formed at the periphery of a well deeper than the source and drain of the MOS semiconductor device. CONSTITUTION:A p-type channel MOSFET Q1 is formed of a source S1, a drain D1 and a gate G1 by P diffusion partially on the surface of an n<->-type substrate 1. Then, an n-type channel MOSFET Q2 is formed of a source S2, a drain D2 and a gate G2 by N diffusion on the surface of the p<->-type well 2 on the substrate 1.  Thereafter, an n<+>-type guard band 4 is formed on the surface of the n<->-type substrate 1 to surround the p-type well 2. At this time the diffusion depth d2 of the  band 4 is so formed as to be deeper than the difffusion depth d1 of the source and  drain of the MOSFET. Thus, the hFE of a bipolar transistor formed between the  MOSFET Q1 and the MOSFET Q2 can be lowered to improve the latchup strength  thereof.

Title: Preparation of thermal plate
Inventor: NISHIKAWA MASAHARU
IPC: B41C1/055
Filed: 1984-03-16
Abstract: PURPOSE:To enable to prepare a draft for heat-sensitive plate making for a draft text by using a draft prepared by a dry type toner having a flash-beam absorption index less than 1, the flash-beam absorption index thereof is lower than a conventional dry type toner, as a draft picture section and copying the draft text by a copier, etc. employing the dry type toner as a developer. CONSTITUTION:Carbon black has excellent absorption efficiency of light energy 5 in a wavelength range extending over near infrared rays from visible rays, and the surface area thereof per weight is increased extremely because carbon black is brought previously to a fine powder state. Consequently, the absorption index of flash beams substantially reaches to 1 when dry type toner particles of 10-12 micron are manufactured in the recipe of the mixing ratio. Such high absorption efficiency generates trouble on heat-sensitive plate making. On the contrary, since the quantity of carbon black is reduced in the typical structure of a toner 15 in which the quantity of carbon black 14 to a resin 13 is minimized and the light energy absorption index of the toner is lowered, one part of flash beams 5 pass through the toner particles 15 via the particles of carbon black 14, thus obtaining the dry type toner having the intermediate absorption index less than 1.
