Title: Concrete composition
Inventor: KOBAYASHI TATSUO
IPC: C04B28/02
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To obtain concrete having high strength and toughness by using natural zeolite having a base substitution function as aggregate and mixing a high- polymer aq. emulsion and cement therewith under agitation, thereby forming the concrete. SOLUTION: This concrete compsn. is formed by using the natural zeolite having the base substitution function as the aggregate, adding inorg. filler agents and fibrous reinforcing materials and mixing the high-polymer aq. emulsion and the cement therewith under agitation. The water in the high-polymer aq. emulsion is electrolyzed by the permanent charge by the base substitution function of the natural zeolite to generate hydrogen and to accelerate the water reducing effect reaction of the hydraulic cement. Further, the crystal structure axes of the zeolite are misaligned and, therefore, the charge accumulation quantity is changed by grain sizes, by which the initial strength development rate of the concrete may be changed. Pyroelectric self-firing is induced by the effect of the permanent charge, by which high hardness is obtd.  An acrylic resin is used for the high polymer of the high-polymer aq. emulsion and the water having the small clusters of molecules and high penetrability is preferably used.

IPC: G06F13/00
Filed: 1989-05-11
Abstract: PURPOSE:To always ensure the normal restart of an electronic computer system by transferring a program, etc., to a nonvolatile memory from an auxiliary storage when the specific data stored in a volatile memory is not equal to the data written previously into the auxiliary storage when the computer system is restarted. CONSTITUTION:An initialization program checks whether the contents of a volatile memory 3 are equal to the specific data or not. If so, an on-line program stored in the memory 3 is carried out. If not, an on-line program is transferred from an auxiliary storage 5 and a specific program is written into a specific address of the memory 3. Then the on-line program is executed. If the contents of the specific address are volatilized owing to the cut-off of power supply of a battery back-up device 4 and not equal to the specific data, the on-line program is transferred to the memory 3 from the storage 5 and written there. Then the on-line program is executed.

Filed: 1990-05-02
Abstract: PURPOSE:To improve the effective utilizing efficiency of a spectrum with simple and easy constitution without provision of an externally mounted low pass filter by reading a part waveform from a part waveform memory sequentially and outputting it as a PN code in response to a configuration pattern of a binarized code. CONSTITUTION:Four kinds of configuration patterns are given to a low pass filter, from which each of part waveform sets is subject to multivalue processing and the result is stored in each area of a ROM 54 (part wave memory). A part waveform corresponding to each of pattern detection signals C0-C3 is read sequentially from the ROM 54 to obtain a PN code (d). Since the PN code (d) passes through a low pass filter, when the code is inputted to a mixer, the power density spectrum does not include a side lobe and the spectrum utilizing efficiency of a transmission radio wave is improved.

Title: Suspension device
Inventor: TEZUKA TAKASHI
IPC: B60G17/005
Filed: 1993-04-20
Abstract: PURPOSE:To eliminate any shock when the lock condition having a leaf spring deflected to the maximum is released. CONSTITUTION:When a pilot poppet 13 is opened by a pilot piston 12, a main poppet 12 is pushed by a press part 23 of a rod 7. However, since a deflection amount of a leaf spring is large in the initial stage, pressure in a back pressure chamber 20 is also increased by that deflection amount. Thus, in this initial stage, the main poppet 13 is not opened by the thrust of the pilot piston 12. However, when the deflection amount of the leaf spring is reduce, the pressure in the back pressure chamber 20 is also inevitable reduced, so that the thrust of the pilot piston 12 then overcomes the force of the leaf spring to open the main poppet 12.

Abstract: PURPOSE:To prevent the FM modulation distortion or the asymmetricity of FM modulation by using a voltage controlled oscillator and generating a frequency modulation signal around a prescribed carrier frequency so as to apply frequency mixing to the carrier whose frequency is changed within a desired frequency range. CONSTITUTION:An FM modulator 11 consists of a VCO.
