Title: Locking device for ceramics bearing
Inventor: SAITO MASARU
IPC: F16C35/063
Filed: 1985-05-04
Abstract: PURPOSE:To make a bearing accurately keepable to the specified position, by making both sides of a bearing inner ring and a bearing inner ring keeper contact with each other on a point, while maintaining the extent of clamping force with both ends of the inner ring. CONSTITUTION:The flank of a bearing inner ring keeper 3 at the side of a bearing inner ring 2a is formed into a conic surface in the same angle as that of the inner ring 2a. The bearing inner ring keeper 3, after being inserted into a shaft 1, makes both conic surfaces closely contact with each other, and presses the bearing inner ring 2a to a large diametral part of the shift 1, locking it tight thereto. In this connection, the flank at the opposite side to the inner ring keeper 3 of the bearing inner ring 2a is also formed into a conic surface. Accordingly, both come to point contact, absorbing an expansion difference, due to heat, between the shaft, the bearing inner ring and the bearing inner ring keeper, thus a bearing is keepable to the specified position in an accurate manner.

IPC: G06F21/34
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To obtain a processing system preventing any illegal acting person from executing any illegal processing. SOLUTION: A storage device generates a pseudo random number (key data k), and calculates a function value g(k), and rearranges each bit of the key data k and the function value g(k) in a prescribed method, and transmits it to terminal equipment, and calculates a function value f(k) (S4-S10). The terminal equipment receives the data (S22), and calculates a function g(k) (S24). The terminal equipment compares the received g(k) with the calculated g(k), and when they are not made coincident (NO in S28), the terminal equipment stops access to the storage device (S36), and when they are made coincident (YES in S28), the terminal equipment calculates the function f(k), and transmits it to the storage device (S30-S34).  The storage device compares the calculated f(k) with the received f(k) (S12), and decides the propriety of access from the terminal equipment according to the compared result (S14-S18).

Abstract: PURPOSE:To produce a high-calory gas by thermally decomposing a solid combustible waste to obtain an oleaginous hydrocarbon and gasifying the hydrocarbon. CONSTITUTION:A solid combustible waste, such as a synthetic resin or a rubber, is crushed. The crushed waste is fed into a carbonization region 13 of a pyrolytic reaction column 10 by means of a continuous intermittent raw material autofeeder 15, and thermally decomposed at 750-1,000 deg.C, thereby forming a gas and a carbide. The carbide is discharged by an extraction device 25. On the other hand, the classification of the gas is conducted, thereby obtaining an oleaginous hydrocarbon. The hydrocarbon is fed into a gas cracking reaction column 50, and injected into a plurality of separate cracking tubes 53 in which cracking is performed. Thus, a gas and a carbide are formed. The classification of the gas is separately conducted to recover a low or medium-gravity product oil. The product oil is recycled and re-cracked. By the above procedure, continuous pyrolytic carbonization of different-phase materials, i.e., solid and liq. materials, is conducted to obtain a lower hydrocarbon gas. Subsequently, this gas and the hydrocarbon gas obtd. by the reaction column 10 are fed into a gas cooling classifier 70 and rotary centrifuged to conduct classification into three phases, i.e., gas, liq. and solid phases. The gas is fed into an apparatus 90, wherein scrubbing, neutralization, filtration and purification are performed.

Abstract: PURPOSE: To make it possible to vibrate a slide plate for an immuno-chemical diagnosis mechanically and uniformly by using a slide support plate which is freely tiltable in any direction by a mechanism of specific structure.  
     CONSTITUTION: This unit consists of input axle 4, clank member 20, lever 22, spherical free coupling piece 28, slide supporter 32, etc. Once rotation driving source 12 is actuated, input axle 4 rotates and bearing member 2 is supported by short axle 6, so that reciprocative tilting movement will be attained as shown by arrows (a) and (b). Then, laver 22 is put into composite motion of reciprocation shown by arrows (c) and (d) and that shown by arrows (e) and (f). This motion permits slide support plate 46 to slant reciprocally in the composite direction of arrows (g) and (h) and arrows (h) and (k) by way of transmission arm 33 and free coupling piece 28. Consequently, the slide plate can be put into required mechanical vibrating motion.

Filed: 1981-06-18
Abstract: PURPOSE:To reduce the generated loss of a Zener diode for voltage cliper, by supplying base current of a transistor (TR) for inverse bias supply which is conducted when a gate turn-off thyristor GTO is turned off, through the cathode and gate of the GTO. CONSTITUTION:A GTO1 is turned on by applying a signal 14 to a transistor (TR)10. To turn off the GTO1, a signal 12a is applied to a TR6. Then, a part of a current via the cathode and gate of the GTO1 is applied to the base of the TR6. Thus, the TR6 is turned on, an inverted bias is applied to the cathode and gate of the GTO1 and the GTO1 tends to turn off. Thus, the impedance between the cathode and gate of the GTO1 starts increasing and the base current of the TR6 is reduced, then the voltage is dropped across a Zener diode 3 and the current flowing to the diode 3 is reduced.

IPC: B41J2/52
Filed: 1988-04-18
Abstract: PURPOSE:To obtain an output image whose density coincides with that of an input image, by calculating a correction quantity from the error between the variable density value of the input image and that of the output image and correcting the variable density value of the pixel at the present scanning position on the basis of said correction quantity. CONSTITUTION:The variable density value data 30 processed by an image processor 3 and the correction quantity C obtained by an operation circuit 307 are inputted to an adder 302 to be added to each other. A comparator 303 compares the variable density value data 31 obtained by this addition processing with the threshold value data 32 from a threshold value pattern memory 301 and, when the variable density value is equal to or larger than the threshold value data, '1' is outputted and, when the former is smaller than the latter, '0' is outputted to perform binarization. A subtractor 305 calculates the error generated between the calculated actual output variable density value 33 and the input variable density value to output the same to the operation circuit 307. The operation circuit 307 performs the weighting operation of the error data and calculates the correction quantity C of the present scanning pixel 6 to feed back the same to the adder 302. The adder 302 adds the variable density value 30 of the present scanning pixel to the correction quantity C to correct the variable density value of the present scanning pixel.

Title: Obstacle detecting device for shutter
Inventor: KIKUTANI KAZUO
IPC: E06B9/80
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To safely control the opening/closing of a shutter by giving prompt information of trouble in an obstacle detector to detect an obstacle. SOLUTION: When a shutter is lowered to be closed and passed down through a pregrounding position detecting means 7, a detection signal is output. A timer 14 is thus activated to time up after a time equivalent to the shutter contacting a floor elapsed. An operation judgement means 10 judges the detecting means 5 to normally operates when the detecting means 5 outputs the detection signal with the shutter contacting the floor before the timer 14 times up. On the other hand, if the detecting means 5 does not output the detection signal when the timer 14 times up, the detecting means 5 is judged to abnormally operate, so that the abnormal condition is informed and output from an information means 17 during opening the shutter.
