Title: Division device
Inventor: ASAI HITOHISA
IPC: G06F7/52
Filed: 1978-10-16
Abstract: PURPOSE: To obtain the quotient of the desired accuracy through the calculation of the first several terms of the series development by installing the divisor register, the multiplication means to decide the acceleration constant and the convergence ratio, the logic circuit to decide the acceleration facter, the dividend quotient register and the control unit each.  
     CONSTITUTION: The following component parts are provided: divisor register 23 to hold divisor B; multiplication circuit 26 to carry out the repetitive calculation to decide acceleration constant a i  and convergence ratio q f ; logic circuit 27 to decide acceleration facter b k ; dividend quotient register 28 to carry out the multiplication by receiving devidend A, constant a i  and factor b k ; and control circuit 22 to give the control to the operation sequence. Register 23 sends the D n -notation group which is decided based on divisor B plus its complement a 0  to register 24 to give the multiplication at circuit 26. And in case q i  is outside the prescribed numerical value, the calculation is given newly to constant a i  and q i+j . If this calculation value is within the prescribed numerical value range, the value is sent to circuit 27 in the form of convergence ratio q f . At circuit 27 q f   2  is obtained from q f , and the calculation is continued until prescribed b k  is decided while having the comparison with the error tolerance. Then the quotient obtained through multiplication of devidend A, constant a i  and factor b k  is sent out through register 28 in the form of the approximation quotient of the desired accuracy.

Title: Quantizer for picture compression
Inventor: SAITO HIROSHI
IPC: H04N19/93
Filed: 1993-05-28
Abstract: PURPOSE:To provide a quantizer for picture compression in which interchangeability between orthogonal transformation and each kind of encoding standard using variable length encoding can be completely maintained, and compressing efficiency can be improved. CONSTITUTION:The product of NXN pieces of basic quantization step matrixes 10 and a quantization parameter 11 is obtained by a first multiplier 12. Then, a quantization step is converted into an inverse number obtained as an integer by a fixed decimal point approximation by an inverse number generating means 14 by K bit round-down when the quantization step is an even number, and by an inverse number generating means 15 by K bit round-off when the quantization step is an odd number. Then, the product of an orthogonal transformation coefficient and the inverse number is obtained, and quantization is executed by a second multiplier 13.

Title: Correction type quasi-instantaneous compression differential coding system
Inventor: TAKEGAHARA TOSHIYUKI
IPC: H03M7/38
Filed: 1987-05-25
Abstract: PURPOSE:To suppress the distortion to a small value by comparing a locally demodulated output with an original signal at a sender side so as to control the differential output properly thereby correcting the error of a low frequency signal in the differential companding. CONSTITUTION:A differential signal 24 is subject to quasi-instantaneous compression by a compressor 14 by using a range signal 8, a differential compression signal 25 is outputted and expanded by an expander 15 by using the range signal 8, and a locally demodulated output 20 is outputted as an original digital signal by an adder 16 and a demodulated delay signal 26 via a one-sample delay device 17 and an accumulated error eliminating device 18. In such a case, since the demodulated delay signal 26 is substantially identical to a one- sample delay signal 27 via a one-sample delay device 10 and an accumulation error eliminating device 11, an error output 28 is obtained by comparing the two signals at a comparator 19. A level controller 13 increases/decreases the differential output to apply the control to focus the error output 28 into zero. Thus, the correction making the differential signal 24 closer to the true value is attained.

Title: Simple wheel testing equipment
Inventor: YAMADA TOSHIO
IPC: G01M17/02
Filed: 1978-10-17
Abstract: PURPOSE: To obtain a wheel testing equipment which can easily test durability, etc., by turning a tested wheel in contact with the external circumference of a rotary drum and then by giving the tested wheel an actual speed and weight equivalent to an run.  
     CONSTITUTION: Wheel A to be tested is fitted to rotary arm 18 and then turned in contact with the external circumference of rotary drum 5. In this case, fitting- height adjustment bolts 12 and 13 are turned to make rotary arm 18 nearly horizontal, thereby adjusting the fitting height of fitting member 14 of rotary arm 18. In this state, run-driving variable-speed motor 5 is driven to turn tested wheel A through rotary drum 5 in a run state similar to an actual run. At the same time, take-up drum 27 is adequately turned by actuating driving motor 28 to take up wire rope 24 while lowering the rotary arm by turning through coil spring 2, thereby applying the same weight as the run to tested wheel A. In this way, the durability of the wheel can easily be tested.

Title: Protection device of electric apparatus for vehicle
Inventor: YAMAMOTO NOBORU
IPC: H05B41/16
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To protect an electric apparatus for a vehicle without causing a fuse to blow when a battery is in reverse connection. SOLUTION: When a battery 1 is mounted in reverted polarity, reverse voltage which is going to be impressed on a discharge lamp device is shut off by the withstand voltage between drain and source of a MOS transistor 21 (withstand voltage of a parasitic diode formed in MOS transistor). Accordingly no over-current flows in a fuse 50, which can therefore be prevented from blowing. Just after turn-off of an ignition switch IG, a large voltage of positive polarity is generated at the earth terminal while a large voltage of negative polarity generated at the power source terminal. At this time, a gate voltage is impressed on the gate of the MOS transistor 21 by the electric charges stored in a capacitor 19, so that the MOS transistor 21 is put in the on condition forcedly.

Title: Magnetic head support
Inventor: NISHIMURA KOJI
IPC: G11B17/34
Filed: 1986-06-04
Abstract: PURPOSE:To reduce vibration generated between a head and a medium and to attain the contact stability at recording/reproduction by providing a pad made of a hard material and supporting the pad by a gimbal spring and a damper. CONSTITUTION:The pad 1 is fixed to the gimbal spring 2 and the gimbal spring 2 is fitted to a support main body 4 via the damper 3. Since a hard material is used for the pad 1, the pad is hard and no deformation is caused on the surface of the pad 1 in case of the contact between the head and the medium. Even if the pad is slided for a long period, no reduction in the reproduced output is caused. Since the pad 1 is supported by the gimbal 2, the contact stability between the head 5 and the medium 6 is very excellent and the damper 3 absorbs the vibration, then the reproduced output is not lowered even after the sliding for a long period and no vibration is caused in the head support system.
