Abstract: PURPOSE:To avoid producing any drawback in driving stability, turnability, etc., by prohibiting the lock of a torque distributing device under the specified driving state even in case there is a manual input having the torque distributing device locked. CONSTITUTION:A command, locking operation of a clutch 15 which controls a torque distributing quantity to an interval between wheels at right and left and before and behind, is inputted into a control unit 24 with a pushbutton 30c. And, a hydraulic pressure controlling device 23 is controlled, a working hydraulic pressure is fed, clamping a clutch 15, and both symmetrical output shaft 12 and 16 are made to come into a state of being directly coupled, thereby prohibiting any torque distribution. However, at the time oof inputting a car speed Sv of less than the specified value, a steering angle Stheta of more than the specified value, a kickdown signal and a braking signal, a feeding current out of the control unit 24 is set to zero, operation of the hydraulic pressure control valve 23 is closed, and working hydraulic pressure for the clutch 15 is brought to zero. And, a lock of the torque distributing device is made so as not to be done. In consequence, any drawback is prevented from occurring in driving stability, turnability, brakeability, etc., in the specified driving condition.

Title: Timing extracting circuit
Inventor: SEGAMI KOICHI
IPC: H04L7/027
Filed: 1987-01-30
Abstract: PURPOSE:To extract a timing component stably by branching one data input into two systems, connecting a delay line and a capacitor in series with a one signal line branched from an input section to apply retarding and inputting the other signal to an adder circuit where a threshold value is set respectively to both the signals simply through a capacitor. CONSTITUTION:When an input data is the NRZ code, a data of an NRZ waveform is inputted to an input terminal 5 and branched into two. Then one signal is inputted to a delay circuit 8 and the signal waveform is delayed by 1/fb (fb is a bit rate). The delayed data and the other branched data without any delay are differentiated by a capacitor C1 and parallel connection resistor (R2.R3/(R2+R3)). Each differentiated waveform is inputted to an adder circuit via emitter followers 15, 16. Since the pulse interval of the output signal Vtheta depends on the delay time 1/fb of the delay circuit 8 only, so long as the delay time is set to 1/fb independently of the pulse width of the input data, the output having the output timing component is obtained.

Title: Adaptive receiver
Inventor: FUJIMOTO YOSHITOSHI
IPC: H04J1/00
Filed: 1998-01-15
Abstract: PROBLEM TO BE SOLVED: To improve communication quality of a multi-carrier transmission system in the case that a plurality of the same signal incoming waves are in existence. SOLUTION: A branching device 3 and a frequency characteristic correction device 2 apply a signal processing to a high frequency signal sent by a plurality of carriers to obtain a high frequency signal branched to each carrier, where distortion due to a propagation path frequency characteristic is compensated. The high frequency signal thus obtained is given to a controller 4 and a demodulator 5. The signal received by the demodulator 5 is demodulates and a parallel serial converter 6 reproduces original data. The controller 4 determines a weight coefficient so that time fluctuation of one received carrier is minimized and controls the frequency characteristic correction device 2. As a result, only one of arrived waves is extracted and even when a plurality of the same signals are received, transmission data are accurately recovered.

Title: Electrode base material for discharge
Inventor: TAKASE TOSHIAKI
IPC: G03G15/02
Filed: 1993-01-13
Abstract: PURPOSE:To minimize reduction in discharge property and perform an uniform discharge with good efficiency by providing a conductive fiber sheet having a fiber density of 3500m/cm<3> or more, and setting the surface resistance of this sheet to 1X10<0>-1X10<9>OMEGA/opening. CONSTITUTION:Fiber density is a length occupied by a fiber per 1cm<3>, and shown as the sum of lengths of individual fibers in case of staple. Since the sheet is difficult to discharge when the fiber density is less than 3500m/cm<3>, the application of a high voltage is required, and even if it discharges, a material to be charged can not be uniformly charged, and the fiber density is desirably 4500m/cm<3> or more. Since the sheet more easily discharges when the fiber diameter is 10mum or less, the sheet more easily discharges, and when the fiber diameter is smaller than 1mum, durability is poor. The fiber diameter is thus set to 1-10mum. When the surface resistance of a rate is less than 1x10<0>OMEGA/opening, the sheet is difficult to uniformly stably discharge, and when the surface resistance exceeds 1X10<9> OMEGA/opening, application of high voltage is required, so that toner, paper dust and dust are easy to adhere, and discharge property is lowered.

CONSTITUTION:At first, copper foil subjected to cold rolling by the conventional well-known method is obtd. This copper foil is subjected to heating treatment at >=180 deg.C in an inert gas atmosphere or in a vacuum. Before the heating treatment is executed, if desired, degreasing treatment by the conventional well known organic solvent may be executed.

The wetting index of the copper foil small in the residual amt. of the rolling oil is regulated to >=34 (dyne/cm), and its water wettability is made good. Thus, at the time of plating the copper foil with a film made of synthetic resin, the surface of the copper foil can uniformly be coated with and adhesive soln. or the like, or by the reduction of the rolling oil interposed between the copper foil and the film made of synthetic resin, the adhesive strength between the copper foil and the film made of synthetic resin improves to better the durability of the laminated product.

Title: Metal die for punching
Inventor: NAITO KINSHIRO
IPC: B21D28/14
Filed: 1988-02-02
Abstract: PURPOSE:To perform cutting by small force by forming a flat part, separating an outline part which pushes a punch into a die at plural points, on the bottom of the punch and also forming shearing corner parts whose height is gradually reduced from the flat part in the right and left directions along the outline part from the separating points. CONSTITUTION:A shape of an outline part 25 which pushes the bottom of a punch 3 into a die 5 and performs shearing action is formed to be a rectangular quadrangle section. As for a punch 3 shown by an inverted bird's-eye illustration, a flat bottom and a lozenge shaped face 27 is formed on the bottom central part of four sides forming the outline part 25 and the face 27 divides the rectangular quadrangle shape of the part 25 into a right and a left parts at about central part 29. Respective right-angled triangle parts at four corners are shearing corner parts and edge lines 33 which the outline part 25 crosses at four corners are in the lowest position from the flat face 27. Hence, shearing is performable by a comparatively low pressure, a large sound generated at hitting the flat face against the top of a stock to be worked is not generated, and the sheared stock is not deformed in an unbalanced shape because the shearing angles are laterally symmetrical.
