Filed: 1984-04-17
Abstract: PURPOSE:To improve economical efficiency and reliability due to decrease in the number of required parts by inputting a product obtained by multiplying the result of the first operation by a twist coefficient to the same discrete Fourier transform arithmetic unit (DFT). CONSTITUTION:Data taken out r at a time in the direction of column from the first and change circuits CT22 are supplied to a DFT20 through a switching circuit 23. The switching circuit 23 switches outputs of the first CT22 and outputs of the second CT24 at every tauhr of the DFT20 and leads to the DFT20. Outputs of the DFT20 are switched at every tauhr, and arithmetic outputs of data from the first CT22 are inputted to a multiplier 25, and outputs of data from the second CT24 are inputted to an output register 28. Output data of r in number, of the multiplier 25 are stored in the second buffer 27, and transferred to the second CT24.

Title: Speed signal detecting circuit of encoder
Inventor: TAKEDA IKUO
IPC: G01D5/245
Filed: 1988-03-29
Abstract: PURPOSE:To remove the influence of ripple components included in a tachometer signal, by obtaining said tachometer signal from a signal multiplied step by step corresponding to a positional signal in the case where two sine wave signals from the main body of an encoder are multiplied step by step thereby to obtain said positional signal. CONSTITUTION:A signal of two phases, namely, phase A and phase B by the operation of a main body 11 of an encoder is turned to be four pairs of signals having the phase shifted in a phase dividing circuit unit 12. The signals are then multiplied in multipliers 31-34 and 39, 40 respectively to have a frequency four times that of the original signal. Thereafter, the signals are converted in a tachometer signal converting circuit 15 thereby to obtain a speed signal including ripple component having a frequency component 16 times of that of the original signal. Meanwhile, 8 outputs from the circuit 12 are multiplied four times in a signal synthesizing circuit unit 14 and added to a direction determining pulse circuit 17 through a comparison circuit unit 16, thus obtaining a pulse signal multiplied 16 times. Since this pulse signal is obtained at the same position as the tachometer signal, the speed errors of the signal can be removed.

Title: Sintered cathode body and its production
Inventor: HOTSUTA SADAKICHI
IPC: H01J1/14
Filed: 1979-06-21
Abstract: PURPOSE: To obtain the sintered cathode body which is stable in the contact between the base body and sintered body and is superior in volume productivity by coating Ni paste on the base body metal and sintering, then pressing the mixed powder to mold the same and sintering the molding.  
     CONSTITUTION: Ni paste 8 is deposited on the base body metal 7 composed primarily of Ni having been heat-treated in a hydrogen atmosphere or vacuum and is then dried. This is heated in a hydrogen atmosphere or vacuum to bake the Ni powder contained in the Ni paste 8 to the base body metal 7, whereby porous rough surfaces are formed. This is installed in a molding die 6, and the mixed powder 9 containing the high-melting-point metal powder composed primarily of Ni is put on the Ni powder layer 8, thence static pressure is applied between knock-out 10 and punch 11 to compression-mold the powder which is then sintered. The base body metal side of the Ni powder sintered layer 14 of the sintered cathode body obtained by this method perfectly sinters to the base body metal 12 and the mixed powder sintered body side becomes firmly intermeshed with the mixed powder sintered body 13.

Title: Matrix circuit
Inventor: SHIEDA MASAHIRO
IPC: H03K17/62
Filed: 1979-06-21
Abstract: PURPOSE:To make it possible to add a positive-direction current as well as a negative-direction current to a load without damage of the selection function of the load, by connecting unit circuits, where switch circuits using threshold voltage elements and loads are connected in series, into a matrix. CONSTITUTION:The signal current from signal source 1 is input or output to input bus 3 and output bus 4, and input branch lines 61...63 are connected from bus 3 through input switches 51...53, and output branch lines 81...83 are connected from bus 4 through output switches 71...73. Threshold voltage element 11 flows a current forward among branch lines 61...63 and 81...83 and stops the current until the applied voltage reaches a prescribed threshold when the voltage is applied backward and flows the current backward when the voltage exceeds the threshold. Unit circuits 14 where switch circuits 12 using elements 11 and loads 13 are connected in series are connected into a matrix. As a result, a positive-direction current as well as a negative-direction current can be added to the load without damage of the selection function of the load.

Title: Sleeve-shaped mounting device
Inventor: GOTO KATSUHIRO
IPC: F16F15/08
Filed: 1989-03-30
Abstract: PURPOSE:To produce an excellent vibration isolating effect for input vibration having a medium and high frequency by providing an elastic connecting part between an inner and an outer sleeve fittings with a vibration system formed of a supporting arm and a mass body to avoid an increase, dynamic spring constant occurring with an increase in input vibration frequency in a mounting. CONSTITUTION:When vibration is inputted between an inner and an outer sleeve fittings 10, 12 to make the inner sleeve fittings move relatively to the outer sleeve fittings 12, force opposite to the displacement of the inner sleeve fittings 10 is generated against a mass member 26 from its insertia force. A fixed moment then effects an elastic connecting part 20 serving as a vibration isolating body on the insertia force of the mass member 26 through a supporting arm 24 in a direction where the moment decreases vibration transmissibility. Thus the weight of the mass member 26 and the rigidity of a supporting arm 24 are adjusted to facilitate the proper tuning of a frequency band where mount-vibration isolating characteristics is turned into a mode produced with a low dynamic spring. Increase, occurring with increase in input vibration frequency, in a mount-dynamic spring constant can therefore be avoided to lessen the vibration transmissibility in inputting the vibration having about tens- hundreds frequency.
