Title: Rubber composite for tread
Inventor: MINAGAWA YASUHISA
IPC: C08K7/22
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To increase friction on both dry-on-ice and wet-on-ice roads by adding a specific size of porous particles to a rubber base material at a specific ratio. SOLUTION: To 100 wt. parts of rubber base material are added 2-30 wt. parts of porous particles 2 having an average particle diameter of 20 μm or less and a specific surface area of 800 m2/g or more. Accordingly, on the surface of rubber 1, many porous particles 2 appear, whereby an uneven face is formed. This uneven face exhibits an edge effect of scraping off an ice road, and exhibits an effect of removing water by absorbing a water film on the ice surface. As a result, large friction is generated on an icy road. Moreover, since the diameter of the porous particles is small, the uneven portion becomes minute such that contact area with the road becomes large. Therefore, the effect of removing a water film and the edge effect can be effectively exhibited on both dry-on-ice and wet-on-ice roads. As a result, considerably high friction can be obtained.

Title: Measuring method of soundness of zirconium alloy in nuclear reactor
Inventor: KUWAE YOSHINORI
IPC: G01N27/72
Filed: 1982-02-10
Abstract: PURPOSE:To measure aging soundness nondestructively and easily, by measuring the thicknesses of the oxide layers produced on the surface of zirconium alloys nondestructively and determining the min. thicknesses of the alloy bases from the max. thicknesses thereof. CONSTITUTION:Test pieces of zirconium alloys having the same material quality as the quality of the zirconium alloys in a nuclear reactor to be measured are placed under accelerated oxidation test conditions, and are removed at every specified time, then the max. thicknesses of the oxide layers produced on the respective surfaces as well as the min. thicknesses of the matrices are measured. The relations between the max. thicknesses of the oxide layers and the min. thicknesses of the matrices of the test pieces are determined by a method of least squares in accordance with the measured values. The max. thickness of the oxide layers in the channel box of the actual reactor is measured by an eddy current method, and the value is substituted in the relations, by which the min. thickness of the matrices is determined. The value is compared with the limit value of the thicknesses of the matrices, whereby soundness is decided.

Title: Torque transmission member and image forming device using the same
Inventor: HIROTA SHOJI
IPC: F16C13/00
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a torque transmission member of a constant angular velocity at a constant peripheral velocity by using a part of one cylindrical surface as a supported cylindrical surface rotatably supported by a bearing, and forming torque transmission teeth at the other part. SOLUTION: A supporting cylindrical surface Sa of a torque transmission member 4 is rotatably supported by a bearing 6, so that the centerline of the cylindrical surface Sa coincides with a rotation axis. Torque transmission teeth 5 are formed on the same cylindrical surface as the cylindrical surface Sa, so that the center of a pitch circle of the teeth 5 is on the centerline of the cylindrical surface Sa, and when torque of constant peripheral velocity is transmitted to the teeth 5, the transmission member 4 is rotated at constant peripheral velocity and constant angular velocity. A member connected to be rotated integrally with the transmission member 4 is therefore rotated at constant peripheral velocity and constant angular velocity in the case of the centerline of the outer peripheral surface coinciding with the actual rotation axis.  In the case of not coinciding, the peripheral velocity fluctuates, but the member is rotated at constant angular velocity.

The counter 10 divides fine grains to each size by using a dust monitor and counts them. In such a way, the grain diameter and the number of pieces of the fine grains can be measured exactly, efficiently and continuously.

Abstract: PURPOSE:To realize the high speed communication by implementing quick processing to a frame received continuously to improve the efficiency of the entire system. CONSTITUTION:A flag detection circuit 1 and an S/P conversion circuit 2 convert a consecutive serial reception data X into a parallel signal.

Title: High pressure valve
Inventor: SOMEYA HISAO
IPC: F16K31/163
Filed: 1991-01-22
Abstract: PURPOSE:To open and close a high pressure valve while using small pilot pressure by converting the linear motion of a piston moved by air pilot pressure into the swing motion of a power lever so that the motion of the piston may be transferred to a slider after boosted. CONSTITUTION:When air pilot pressure P is applied from an inlet hole 28 to a chamber 27, a piston 23 moves down. A power lever 33 is pushed by this moving down and swing around a fixed shaft 34, and the cam face of the fixed shaft 34 moves up a follower, that is, slider 24. This moving up power is boosted depending upon the lever ratio of the power lever 33 determined by the distance between the shaft 34 and a roller 35 and the distance (s) between the cam face 36 and the shaft 34. Therefore, such big power as being capable of opposing to a stacked coned disc spring 32 can be generated by small power only making the piston 23 move down resulting in the rise of a slider 24.

Title: Frequency synthesizer
Inventor: KURANO TAKANORI
IPC: H04B1/26
Filed: 1986-02-01
Abstract: PURPOSE:To keep a prescribed frequency of a synthesizer output signal after the frequency conversion regardless of the variance of a SAW oscillator by outputting a signal to change the oscillation frequency of the 1st local oscillator from a frequency setting data generator so as to control the oscillation frequency of the voltage controlled reference oscillator. CONSTITUTION:The frequency of a voltage controlled reference oscillator 9' is changed minutely to change slightly the frequency of a voltage controlled oscillator 2 of a double superheterodyne type tuner 1 from the locked frequency substantially thereby cancelling the frequency variance of an intermediate frequency output signal 11. A control data in response to a frequency deviation DELTAf of the SAW oscillator 3 is written in a code converter 14. Since the deviation DELTAf depends on the individual component, the content of the code converter 14 is decided accordingly. Since the correction value of the reference frequency changes even in the same deviation DELTAf when the setting frequency is changed, the code converter 14 has a control data at each setting frequency. The output of the code converter 14 is converted into an analog voltage by a D/A comparator 13 and the result is fed to the voltage controlled type reference oscillator 9'.
