Title: Current limiting structure during motor control by dc chopper circuit
Inventor: NAKAKITA OSAMU
IPC: H02P7/291
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a current limiting structure during control of a motor by a DC chopper circuit which can control the motor current by a pulse signal of the same frequency as in a normal operation even when a trouble occurs. SOLUTION: An operational amplifier 8 and external resistors R1 , R2 , R3 constitute a hysteresis comparator II. The hysteresis comparator II generates a pulse signal P2 which changes its state each time the motor current I detected by a current detector 6 when a CPU 7 has a trouble passes an upper limit value and a lower limit value of the hysteresis comparator II. The pulse signal P2 and a pulse signal P1 which is an output signal of the CPU 7 which has a 100% duty when the CPU 7 has a trouble are logic-operated by an AND circuit 9 and an operation result is output as a pulse signal P3 . By this method, the conduction state of an IGBT 5 can be controlled by the pulse signal P3 which has the same waveform as the pulse signal P2 .

Title: Production of high toughness thick steel plate without segregation
Inventor: YOSHIE ATSUHIKO
IPC: B22D11/00
Filed: 1990-06-07
Abstract: PURPOSE:To obtain a high toughness thick steel plate without macro segregation by opening upper surface of molten steel composed of C, Si, Mn, Al and the balance of Fe at angle of <=10 deg. to the horizontal plane, continuously casting to the temp. between the lqiuidus temp. and the solidus temp. at the specific cooling velocity and rolling at the specific temp. range. CONSTITUTION:The molten steel composed of 0.02-0.25wt.% C, 0.05-0.6% Si, 0.30-2.0% Mn, 0.005-0.10% Al and the balance of Fe with inevitable impurities, is used. Under condition of opening the upper surface of molten steel at the horizontal plane or the angle of <=10 deg. to the horizontal plane, the continuous casting is executed to the temp. between the liquidus temp. and the solidus temp. at >=25 deg.C/min cooling velocity. This cast slab is successively rolled at the temp. range of the inequality I. By continuously casting the molten steel under condition of opening the upper face of molten steel at the angle of <=10 deg., the finish solidified position in the cast slab is made to the most upper surface to prevent formation of the macro segregation. Further, in the case of being slow cooling velocity, as the solidification starts from the upper surface of cast slab, too, this lower limit is made to 25 deg.C/min. By this method, the high toughness thick steel plate without any macro segregation can be efficiently obtd.

Title: Encipherment system
Inventor: NAKAI TOSHIHISA
IPC: H04L9/06
Filed: 1984-07-20
Abstract: PURPOSE:To obtain an encipherment system that cannot be decoded easily with no use of a complicated cipher algorithm by renewing a enciphering/decoding key in a short time and producing the keys at random and independently of a normal sentence which transmits the keys to scatter those keys into the transmission data for encipherment. CONSTITUTION:At first a common key K1 is stored to the encipherment and decoding key buffers BF16 and 24 at both the transmission and reception sides. A switch SW18 is closed and the key K1 is supplied to an encipherment algorithm ALG17. Then the buffer BF16 is made empty and the SW18 is opened. Then a switch SW14 is switched properly between the terminals 11 and 13 to incorporate the key data 27 produced by a random key generator 15. Thus the input data 28 to be supplied to the ALG17 is produced. At the same time, the data 27 is stored to a BPF16. The ALG17 codes the data 28 by the K1 and transmits it to a transmission line 19. When the quantity of the key data stored in the BPF16 reaches its maximum level, the SW18 is cosed and a new key K2 is supplied to the ALG17. Then the BF16 is made empty and the SW14 is opened. The ALG17 codes the data by the K2. At the reception side, an ALG20 decodes data and separates the data 31 from the data 30 to store the key data to a BPF24.

Title: Dynamic signal detecting circuit having all-band response excepting spatial frequency on diagonal line
IPC: H04N11/04
Filed: 1992-06-09
Abstract: PURPOSE: To provide a dynamic signal detecting circuit, having all band response except for a spatial frequency on a diagonal line by restraining chroma information included in a complex video signal by a filter eliminating a high frequency on diagonal line in a spatial frequency region. CONSTITUTION: A frame memory 102 delays the complex video signal 110 which is supplied from an input terminal 100 by one frame. A subtractor 104 performs subtraction of the signal 110, and a response delayed by one frame corresponding to that to detect a difference signal between frames. A horizontal low-pass filter 106 restrains the chroma information included in the horizontal spatial high frequency of the output signal 111 of the subtractor 104, and extracts only dynamic information included in a horizontal low frequency. Thus, much further spatial high-frequency components are included, and the dynamic signal detecting circuit having all-band response, excepting the spatial frequency on the diagonal line, is obtained.

Title: Drill
Inventor: ABE KAZUMASA
IPC: B23B51/00
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To effectively provide an increased life for a tool as a sufficient strength is kept. SOLUTION: In a drill wherein a body clearance 3 having diameter smaller than the size of a margin with a margin 2 left at an outer peripheral surface, the depth of the body clearance 3 is gradually increased away from the margin 2. More preferably, the surface of a drill is coated with a hard film. Thus, even when wear of the tip corner part of a margin 2 is progressed and attains the depth level of the body clearance 3, since the body clearance 3 is formed in a shape that with the progress of separation of it from the margin 2, the body clearance is escaped to the radial inside, this constitution suppresses the progress of wear in a peripheral direction along the tip corner part of the body clearance 3, and during this, wear of the tip of the margin 2 is locally progressed.

Title: Transfer device
Inventor: YAMANAKA TATSUZOU
IPC: G03G15/16
Filed: 1978-12-06
Abstract: PURPOSE: To obtain a device accurate in operation and low in production cost, by changing the polarity of the transfer voltage applied to a transfer roller at every specified copy command count, copy number or copy time determined by the transfer current allowable value.  
     CONSTITUTION: Since nonchargeable toner is used in a magnetic transfer system, the polarity of transfer voltage applied to the core of dielectric roller 5 may be either positive or negative. For example, when a negative transfer voltage is applied to the dielectric roller 5, polarization is accumulated on the surface of dielectric of the roller 5 at the time passes by, which deteriorates the transfer characteristics. To avoid this, before the transfer current drops below the specified allowable value, the polarity of the transfer voltage is inverted to positive by means of a transfer voltage polarity changing switch 13 in response to a signal from a copy command detector 12, then the polarization becomes zero but starts to increase again. Therefore, by repeating the changing of the transfer voltage polarity by the timing given by a copy command, an expensive and reliable magnetic transfer device may be obtained.

Abstract: PURPOSE:To prevent the breakage of the insulation of a gate insulating film by forming a wiring film and an electrode film out of Al base alloy containing one at least one or more kinds out of specified elements by specified quantities, and specifying the thickness of an anodic oxide film. CONSTITUTION:A base alloy film 1 consisting of Al base alloy containing at least one or more kinds of elements, out of Fe, Co, and rare earth elements, by 0.1-10at% is made, and an anodic oxide film 2, 200Angstrom  or over in thickness is made, thus a wiring electrode film 3 consisting of them is made. If the content of alloy within wiring electrode is less than 0.1at.%, the improvement of anode oxidation property becomes insufficient, and an anodic oxide film excellent in high insulation breakdown strength ceases to be gotten, so it is preferably 1at% or over. But, if it is 10at% or over, the specific resistance is over 20muOMEGAcm after heat treatment, and the shortening of the delay time of a gate bus line ceases to be gotten, so it is preferably 5at% or under. If the thickness of the anodic oxide film is less than 200Angstrom , the insulation breakdown strength becomes insufficient, so it is preferably 500Angstrom  or over. Accordingly,the short circuit and the insulation breakage of the gate insulating film can be prevented.
