Title: Transfer device
Inventor: WAKAMATSU KAZUHIRO
IPC: G03G15/16
Filed: 1987-07-08
Abstract: PURPOSE:To suppress the leakage of a charge for transfer in case of the moisture absorption of paper and to prevent the fault in transfer by tightly bringing the paper into contact with a photosensitive drum by means of two paper guiding rollers which are oppositely disposed on the surface of the photosensitive drum through a fine gap and grounding the guiding roller through a resistance. CONSTITUTION:Two paper guiding rollers 8 and 9 constituted of the conductive member grounded through the resistances 32 and 33 are oppositely disposed on the photosensitive drum 1 through the fine gap and the paper is made to pass through the fine gap. The erect aperture edges of the shield electrodes 10 and 11 of a corona discharger 6 for transfer, to which insulating processes are executed, are extended between two paper guiding rollers 8 and 9. Namely, since the paper passes through the fine gap between the photosensitive drum 1 and the paper guiding rollers 8 and 9, the paper is tightly brought into contact with the photosensitive drum 1 even if the stiffness of the paper lowers in case of the moisture absorption. Moreover, the deterioration of transfer function can be prevented because the leakage of the charge for transfer is suppressed by the ground resistances even if electric resistances 32 and 33 are decreased.

Abstract: PURPOSE:To reduce the quantity of communication and labor and time for managing the communication by reducing the number of times of transformation of an input message to one by using a specific transformation method. CONSTITUTION:When a message M having a bit length (i) which is shorter than the binary bit length (k) of the product n=pXq of two prime numbers (p) and (q) is given as input data in a encipherment transformation system of messages using the two prime numbers (p) and (q) as cryptographic keys, transformation M g(A,M)(A II M) is performed on the message M so that Z=g(A,M)(A II M), Jacob(Z,p)=1, and Jacob(Z,q)=1 can be obtained and the square root of Z using the product (n) of the prime numbers (p) and (q) as modulus, namely, C=sq. rt. Z (mod n) is calculated by selecting an appropriate func tion (g) and bit train A by using the Jacobi function defined by Formula I and a symbol indicating the bit train. The calculated results C are used as a ciphered sentence. Thus only one time of transformation is performed on an arbitrary message M. Therefore, a digital signature becomes possible.

Title: Hydraulic pressure controller for antiskid device
Inventor: ARIKAWA TETSUO
IPC: B60T8/46
Filed: 1980-11-29
Abstract: PURPOSE: To prevent a kickback at a brake pedal by a method wherein a valve device is provided on a brake oil supply duct so that a connection with a hydraulic pressure control valve from a master cylinder can be allowed only when hydraulic pressure is more than a fixed value.  
     CONSTITUTION: A wheel cylinder 4 is connected with a master cylinder 1 through a valve device 20 and hydraulic pressure control valves 5 and 6. When brake oil pressure from the master cylinder exceeds a fixed value, a step piston 22 retracts against a spring 23, a spherical valve 24 is seated on a valve seat 25 and a duct 40a is blocked its flow direction of only from the wheel cylinder to the master cylinder. Then, a kickback to a brake pedal 2 under antiskid control disappears. Since the spherical valve 24 is opened when the brake pedal 2 is released and the brake oil pressure is lowered, residual pressure of the wheel cylinder 4 disappears and a dragging of the brake, therefore, is not occurred.

Abstract: PROBLEM TO BE SOLVED: To obtain a base for thin layer magnetic heads having higher perfor mance and consisting of a sintered body obtained by bringing circle-equivalent sizes of Yb2 O3 (which is a sintering assistant) particles to express specific values, on the surface portion of a Al2 O3 -TiC-based sintered body comprising Al2 O3 as a main ingredient. SOLUTION: This sintered body is an Al2 O3 -TiC-based sintered body comprising Al2 O3 as a main ingredient and 25-35 wt.% of TiC, and containing Yb2 O3 particles as a sintering assistant having 0.01 to less that 0.5 μm circle-equivalent sizes as a dispersibility index. Yb2 O3 is preferably included in approximately 0.05-0.3 wt.% based on other ingredients. The sintered body is capable of being remarkably enhanced in its surface quality level after an ion-milling processing, and chipping resistance. Thus, when it is used as the slider of a thin film magnetic head, e.g. when it is processed as a TPC slider by irradiating ions, the surface quality level is enhanced after the processing and reliability of the magnetic head can be enhanced.

Title: Method for descaling hot rolling steel strip
Inventor: TESHIGAWARA SATOSHI
IPC: B21B45/06
Filed: 1990-06-27
Abstract: PURPOSE:To make the combined use for pickling the common steel and the stainless steel (Cr system) possible and to improve the descaling efficiency by making cracks on the surface of steel strip applying the mechanical force on the hot rolling steel strip and further pickling the steel strip with the pickling liquid containing a very small quantity of non-ion interfacial active agent. CONSTITUTION:When the hot rolling steel strip is washed with pickling after generating cracks at the scale layer by applying the mechanical force of the repeated bending, the light rolling reduction or both of them, etc., the pickling liquid invades in the crack and the chemical reaction of the pickling liquid and the scale is accelerated. In this time, by adding a very small quantity (<=0.2Vol%) of non-ion interfacial active agent with penetrating characteristics, the penetration of the pickling liquid to the scale-crack is made good and the chemical reaction is more accelerated. And if it is applied with the grinding roll of non-woven cloth before pickling after generating the crack on the scale layer, it is descaled with the brushing effect of the grinding roll, and also the surface of the remaining scale is made active, then, by immersing it in the pickling liquid added with non-ion interfacial active agent, because of multiplicational effect with the interfacial active agent, the chemical reaction of the pickling liquid and the remaining scale is accelerated, and the descaling effect is improved.
