Title: Weighting circuit
Inventor: KATAKURA MASAYUKI
IPC: H03H15/02
Filed: 1978-08-08
Abstract: PURPOSE:To obtain excellent linearity and to eliminate the DC power consumption, by using two phase input signals of positive and negative phase and MOSFET as variable resistance element. CONSTITUTION:The weighting circuit of the programmable input weighting type transversal filter is constituted with MOSFETQ51 and Q52, the input signals of positive and negative phase are fed to the terminals 32 and 33, and the ratio of addition is changed with the channel conductance, to control the weighting coefficient. That is, in the input and output characteristics of the signal conversion circuit 51 (V1 is the weighting voltage fed to the input terminal 53, and V2, V3 are output voltage), the minimum voltage V1 of V2 and V3 is set less than the cut off voltage of FETQ51 and Q52, resulting in being always in OFF state for either of FETQ51 or Q52, accordingly, this means either one of FETQ51 or Q52 is selected depending on the polarity of the weighting coefficient, and the channel conductance is controlled corresponding to the absolute value of the weighting coefficient.

Title: Vector contorller for induction motor
Inventor: TSUCHIYA TSUNEKAZU
IPC: H02P21/24
Filed: 1982-06-07
Abstract: PURPOSE:To accurately control a vector always irrespective of the temperature of a rotor by accurately computing and simulating the secondary magnetic flux even if the temperature of the rotor varies. CONSTITUTION:The primary current command i1 from a speed control circuit is multiplied by a coefficient unit 27 by a coefficient, and converted to the final value i2 of the torque corresponding current. The final value i2 of the torque corresponding current is added by an adder 28 through the primary delay element circuit 28 having one or more primary delay element by a signal which represents a stator temperature t2 approaching the rotor, thereby obtaining as its output a rotor temperature t1. An electric resistor R2 of the rotor circuit is obtained from the temperature t1 by using an adder 32 and a coefficient unit 33. This is further inputted through the coefficient unit 34 to multipliers 224, 225, 241, thereby correcting the value of the secondary resistance value. In this manner, the resistance of the rotor is variably set in response to the variation of the temperature, thereby reducing the operating error of the magnetic flux caused by the variation in the rotor temperature.

Title: Wheel cylinder
Inventor: JI YAA UU
IPC: F16D65/22
Filed: 1980-07-18
Abstract: A wheel cylinder in a brake assembly includes a housing for movably carrying a pair of pistons. An intermediate wall of the housing separates the pair of pistons from each other and cooperates with each piston to substantially form a first chamber facing one of the pistons and a second chamber facing the other piston. An inlet communicates fluid pressure to the chambers via a first path and a second path within the housing. A pressure responsive member is disposed within one of the paths and is biased to a position opening communication through the one path. When the fluid pressure within one of the chambers reaches a predetermined value, the pressure responsive member is movable to restrict fluid communication to the one chamber while the fluid pressure within the other chamber is free to increase in value during actuation of the wheel cylinder.

Title: Dial pulse sending circuit
Inventor: SAGAWA SHUICHI
IPC: H04M1/31
Filed: 1988-04-22
Abstract: PURPOSE:To prevent the occurrence of a momentary interruption or a pseudo pulse after completion of sending of dial pulses by providing an emitter follower circuit and a capacitor which by-passes the AC component applied to the base of said circuit and making a transistor(TR) conductive during sending of dial pulses. CONSTITUTION:A relay contact 8 is opened and closed in accordance with desired dial pulse standards, and simultaneously, a relay contact 7 is operated. When the relay contact 8 is closed, a TR 1 is made conductive and the time constant is reduced from R2.C1 to (R1//R2) .C1 to improve the waveform characteristic of dial pulses. While dial pulses are sent, a capacitor 6 is charged and the TR 1 is in the saturation area. That is, since the TR 1 is in the conductive state just after the relay contact 7 is released after completion of sending of dial pulses, a momentary interruption of the speaking DC current and a pseudo pulse do not occur.

Filed: 1988-04-22
Abstract: PURPOSE:To decrease the influence of heat on a plastic lens by constituting the optical unit by including a transparent fluid medium having the refractive index higher than the refractive index of air, an optical medium and meniscus lens. CONSTITUTION:The 1st optical unit is constituted, successively from a cathode ray tube 2 toward a screen, of the transparent fluid medium 9 having the refractive index higher than the refractive index of air, the nonfluid medium 3 having a small refracting power, the transparent fluid medium 10 having the refractive index higher than the refractive index of air, and the meniscus lens 4 the convex face of which is directed to the cathode ray tube. The nonfluid medium 3 has such an effect as to obviate the transfer of the heat of the fluid medium 9 to the fluid medium 10. The two fluid media are, therefore, so parted as not to intrude in each other. On the other hand, the meniscus lens 4 is made into an aspherical face by molding a resin such as acrylic having low heat resistance and, therefore, various aberrations are improved and the performance good to the periphery of the screen is obtd. The temp. applied on the plastic meniscus lens is thereby lowered down to the heat resisting temp. or below.

Abstract: PROBLEM TO BE SOLVED: To provide a multi-layer printed circuit board without cracks in an interlayer resin insulating layer. SOLUTION: A mask with an opening is mounted on a core board 30, and a filler is applied by printing to fill the through hole 36 with the filler (step E).
