Title: Thyristor phase control device
Inventor: FUJIOKA HIROKATSU
IPC: H02M1/084
Filed: 1979-04-25
Abstract: PURPOSE:To obtain control signals which have equal firing phase and require no adjustment by inputting a part of the output from a phase signal generator to a counter through a frequency multiplier and the remaining output through a reset  signal generator. CONSTITUTION:Two phase out of three phase is inputted to a phase generator 5 which synchronizes with a power source and has one output. And a part of the output signal in the phase generator is applied to a frequency multiplier 6 which consists of a phase comparator 61, a filter 62, a frequency converter 63 and a frequency demultiplier 64 and the remaining output is applied to a reset signal generator 9 which consists of a differentiator 91 and an integrator 92 and a reset signal holding unit 93. Both outputs are applied to a counter 7 and when no input is present at a reset input terminal Re, an input pulse inputs to an input terminal IN is counted  and distributed in order of amplification.waveform shapers 81, 82...86. In this way, synchronization is easily performed as the output in the differentiator 91 is used as a reset signal for the counter 7.

Title: Antenna system for mobile body
IPC: H01Q3/08
Filed: 1992-03-11
Abstract: PURPOSE:To reduce a directional error with a few axis number by supporting an antenna with a support pole tilted forward so as to expand a drive range of the antenna around the elevating angle. CONSTITUTION:An El axis motor 22 is fixed to a support pole 30 extended obliquely above a drive section 20. The pole 30 has a length and a gradient so that a position of an El axis 14 is set forward by a very small distance DELTAl with respect to a center line of an Az axis 12. The distance DELTAl is selected so that the antenna 10 is not in contention and in blocking with the drive section 20 when the antenna 10 is driven around the axis 14. Furthermore, the gravity center of the pole 30 is set backward from the center line of the axis 12. An antenna support 32 and an RF section 34 are arranged around the axis 14 and the support 32 keeps the weight balance around the axis 14. The antenna 10 is deviated upward by the distance DELTAl with respect to the axis 14. Thus, the contention and blocking between the antenna 10 and the drive section 20 are reduced and the size of a radome is reduced.

Title: Method and device for residue system operation
Inventor: ISHII SHINJI
IPC: G06F7/72
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To obtain the method and device which can perform operation even when the number of bits of a mantissa is larger than the number of bits of a modulus by storing a dividend and a divisor in registers, and shifting the whole divisor and performing residue operation up to a digit corresponding to a difference in bit shift quality when the number of the digits of the divisor is less than the number of bits which can be stored. SOLUTION: The modulus C has its bits shifted up to the most significant digit bit of the register for the modulus C to obtain a modulus C' (401). Then the mantissa (a) has its bytes shifted until the most significant digit byte of the register for the mantissa (a) has 1 to obtain a mantissa a' (402). Consequently, a redundant binary operation system is applicable. Then division is started. The end bit of the division, however, is at the digit corresponding to the difference 403 in bit shift quantity between the modulus C' and mantissa a'. The residue is an answer 404. Consequently, advantages of fast operation of the redundant binary operation method are utilized and the limit of the number of operation bits as a disadvantage of the redundant binary operation method can be eliminated.

Filed: 1980-04-23
Abstract: PURPOSE:To execute an extension test without reducing the processing capacity of a network, by constituting so that the pre-extension junctors and the post-extension junctors can be installed together. CONSTITUTION:In case of extension of the network LIN1 and TLN1, at first, the junctor subgroups J2, J3, J4 are connected before blocking the junctor subgroup J1. In the LLN0 and the TLN0, since connectors C4, C5 are connected in parallel with connectors C2, C3, the extension junctor subgroups J2, J3 can be connected without removing the junctor subgroup J1. Even when the extension junctors J2-J4 have been connected, the channel is set by LLN0, J0 or J1 and TLN0 as usual, by leaving said junctors blocked against a general call. When the test has been completed, the processing logic is changed so that the connection processing is executed by the post-extension network constitution against a general call. And, after the processing logic has been changed, the junctor subgroup J1 is detached.

Abstract: PURPOSE:To construct a sheet pile wall having good water-stopping property by quick construction work by a method in which a trench is excavated with a stabilizer liquid supplied to the trench being excavated, a solidifying agent is charged into cohesive sludge in the trench, and a sheet pile is driven under non-hardened condition and the sludge is hardened. CONSTITUTION:Guide walls 1 are set along a portion to be excavated of the ground, and the soil is broken by the cutting edge 5 of an excavator 3 with a trencher 4. Large gravels are discharged through the slits 6 of the trencher 4 to the outside of the trench 2. A stabilizer liquid 8 is supplied into the trench 2 as the same time as excavation is made, and a cement-based solidifying agent is charged into and mixed with cohesive sludge. Under the condition that the sludge is non-hardened, a sheathing body such as concrete sheet pile 9 is penetrated, and the sludge is hardened. Afterwards, the front side of the pile 9 is excavated to form an adjacent sheet pile wall consisting of the pile 9 and the hardened wall 11 to obtain a revetment or underground wall. The construction work can thus be performed at low cost without the need for operation of reclaiming soil, etc., by treating residual soil at low cost.
