Title: Impact tester
Inventor: KAMINAGA RETSU
IPC: G01N3/30
Filed: 1981-09-11
Abstract: PURPOSE:To facilitate the conversion of set impact force value by varying the set values of the amplitude and the frequency of a vibrator base according to a natural frequency in the vibration system supported through an elastic body and a coefficient of restitution between an impact body and a sample. CONSTITUTION:A sample 24 is set on one side section on a pedestal 21 of a vibrator base 20 while a support post 23 is erected pivoting a lever 31 on the other side section. The lever 31 is pivoted rotatably on the support post 23 at one end thereof with a pin 32 while at the other end thereof, an impact body is arranged at the position facing the sample 24 and is supportively hung with a spring 30 mounted on a fixed wall 28. Thus, a vibration system 27 is constructed. When given a vibration by vertically moving the vibration base 20 at an arbitrary frequency, the vibration system 27 resonates. So, the vibrator base 20 is vibrated to match the natural frequency of the vibration system 27. This causes the sample 20 to move so vertically to hit the impact body 26. Thus, the sample 24 gains an impact force.

Filed: 1990-05-31
Abstract: PURPOSE:To eliminate breaks and drop-out of vectors in the vicinity of intersections of vertical and horizontal lines due to centering processing or the other by correcting ruled line vectors in each designated area by a ruled line processing editor. CONSTITUTION:Two points A and B are designated to determine a rectangular correction area (a).

Abstract: PROBLEM TO BE SOLVED: To provide a tunnel boring machine in which a large propulsive force is not required and the machine can be miniaturized and cost can be reduced, and which has a high excavation capacity for natural ground of bed rock and is excellent in excavation efficiency. SOLUTION: A support frame 31 for compressive breakage edges is fixed to the foremost part of a head excavation disk 2 rotatably supported through a bearing 10 at the front end of a tunnel boring machine body 1. A plurality of compressive breakage edges 3 rotatably supported by the support frame 31 are at first brought into contact with natural ground 15 exposed in a shaft and strongly pressed on the bed rock surface while rolling to generate a linear compressive breakage and form a small diameter leading hole. As the compressive cutter edges 3 are thrusted, the edge nearest to the central shaft among separation breakage edges 4b is brought into contact with the external surface of the opening of the leading hole to break the inside part so as to separate it.  Separation breakage edges 4a, 4c fitted to the front face of main struts 21 one after another at every specified distance in the direction that the diameter becomes large are subsequently brought into contact with the exposed face of the bed rock of the natural ground 15 to break the inside part so as to separate it. In this way, a nearly conical heading having cylindrical steps can be formed.

Title: Method for removing adsorbed organic material from hormite-type clay
Inventor: FUKUSHIMA YOSHIAKI
IPC: C01B33/40
Filed: 1989-06-05
Abstract: PURPOSE:To effectively decompose and remove adsorbed organic material from a hormite-type clay mineral without causing the decomposition and collapse of the mineral by subjecting the clay mineral containing adsorbed organic material to wet-oxidation under specific condition. CONSTITUTION:A hormite-type clay mineral containing adsorbed organic material is treated with an oxidizing agent in water having nearly neutral pH at a high temperature. There is no particular restriction in the kind of the oxidizing agent, however, use of hydrogen peroxide solution or oxygen is usual. The amount of the adsorbed organic material in sepiolite or palygorskite is usually <=1wt.% and, in this case, the effect can be achieved by using about 5cc of 10vol.% hydrogen peroxide solution per 10g of sepiolite. Although sufficient wet-oxidation can be carried out by using about 1 pt.wt. of water based on 1 pt.wt. of sepiolite or palygorskite, the operability can be improved by the use of about 5 pts.wt. of water.

Title: Mouse control system
Inventor: ARAI YASUHIRO
IPC: G06F3/0354
Filed: 1989-06-05
Abstract: PURPOSE:To attain the use of a mouse even in an inferior environment by connecting an integrator to a vertical acceleration detector and resetting and unresetting each horizontal integrator based on the output of the integrator connected to the acceleration detector. CONSTITUTION:The outputs of integrators 2 and 4 connected to the outputs of the horizontal acceleration detectors 1 and 3 are turned into the speed signals. These speed signals are integrated to obtain the horizontal shift value of a mouse. On the other hand, the output of an integrator 6 connected to the output of a vertical acceleration detector 5 is also turned into a speed signal. The plus side of this speed signal is equivalent to a case where the mouse is held up. Then the speed signal resets both integrators 2 and 4 and is set at 0. The reset states of integrators 2 and 4 are cancelled at the rise of the negative side of the speed signal. Then the horizontal speed signal is outputted for the measurement of the shift value of the mouse. Consequently, the defective operations due to the mixture of dust can be omitted owing to the lack of a movable part. Furthermore the mouse can be operated regardless of the state of a desk where the mouse is moved.

Filed: 1995-06-09
Abstract: PURPOSE: To simplify the waveform equalization independent of the extent of distortion by switching algorithms in a constitution using a simple evaluation function with respect to waveform equalization in a QAM demodulator. CONSTITUTION: An orthogonal detection means 101 demodulates an input signal into an I signal and a Q signal. TRFs 102 to 105 take the I signal and the Q signal as the inputs to generate distortion eliminating signals. Adders 107 and 108 output the I signal and the Q signal where distortion is eliminated by addition or subtraction of outputs of TRFs 102 to 105. A control means 106 takes the output of the orthogonal demodulator 101 and outputs of adders 107 and 108 as the input to evaluate a maximum value of the absolute value or the sum total of error at that time and switches plural algorithms in accordance with the evaluation result to obtain the tap coefficients to be given to TRFs 102 to 105.
