Title: Spraying fire-extinguishing method
Inventor: NAGAO KENJI
IPC: A62C3/07
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To realize an excellent fire-extinguishing performance and economical property by spraying a water-soluble fire-extinguishing chemical solution the diffusion coefficient of which is a specified value by a specified expansion ratio. SOLUTION: A water-soluble fire-extinguishing chemical solution the diffusion coefficient of which is 5 or higher is emitted from a spraying head in such a manner that the expansion ratio may become less than 5 times, and thus, a suffocation fire-extinction in a plant equipment is performed, and the fire-extinction can be economically performed. The diffusion coefficient is represented by a formula: S=25-(γL+γi). In the formula, S represents the diffusion coefficient, the numeral value of 25 is the surface tension of cyclohexane at 20 deg.C, γL represents the surface tension of the water-soluble fire-extinguishing chemical solution at 20 deg.C, and γi represents the surface tensions of the cyclohexane and the water-soluble fire-extinguishing chemical solution at 20 deg.C. Thus, when a fire-extinguishing experiment is performed with the water-soluble fire-extinguishing chemical with the diffusion coefficient of 5 or higher at the expansion ratio of less than 5 times, a period of time required for the complete fire- extinction is approx. 1/2 to 1/3 compared with a case wherein the water-soluble fire- extinguishing chemical with the diffusion coefficient of less than 5 is used, and such an excellent fire-extinguishing performance can be manifested.

IPC: H04L12/28
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To suppress reduction in a transmission rate due to redundant coding and to avoid redundant coding which becomes invalid by reducing increase in a data quantity due to the redundant coding. SOLUTION: A transmission section T discriminates propriety of reproduction of a clock signal in a reception section R by monitoring a bit arrangement of a transmission data signal that is an original data signal. As a result, when the transmission section T discriminates that the bit arrangement of the transmission data signal is a bit arrangement, by which the reception section can reproduce the clock signal, the transmission section T transmits the transmission data signal without making it a redundant coding, and when the transmission section T discriminates that the bit arrangement of the transmission data signal is a bit arrangement by which the reception section is difficult to reproduce the clock signal, the transmission section T transmits the transmission data signal with redundant coding.

Title: Coefficient determining method for secondary serial compensator for two-inertia resonance system velocity control
Inventor: GO MASARU
IPC: H02P29/40
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To effectively control the axis torsional vibration of two-inertia resonance system, by determining each coefficient of secondary serial compensator from pole placement of a closed loop system, and giving good attenuation coefficient to the control system. SOLUTION: When controlling two-inertia resonance system 1 by a secondary serial compensator Gd(s), a torque command signal T* can be obtained by passing a deviation Δω between a velocity command signal Ω* and a motor velocity ωm into the secondary serial compensator Gd(s). By giving this torque command signal T* to the motor, the motor velocity ωm occurs. A deviation integrated value between the motor velocity ωm and a load velocity ωL becomes a shaft torsional angle θs, and this shaft torsional angle θs is multiplied by a shaft spring constant Ks, and a shaft torsional torque Ts occurs. By giving a deviation between the shaft torsional torque Ts and an external disturbance torque TL of load to the load, the load velocity becomes ωL.  In this case, each coefficient q1, q1 of the secondary serial compensator Gd(s) can be determined from the pole placement of the closed loop system.

IPC: B60R21/20
Filed: 1980-10-15
Abstract: PURPOSE: To provide a secondary collision dampening device utilizing an emergency bag which is normally folded in the form of a spiral and installed between the front seat and obstacles before the seat of an automobile and inflated by a pressurized fluid at the time of a collision to dampen the impact of the driver against interior fittings of the automobile.  
     CONSTITUTION: An emergency bag 4 is folded in the form of a spiral and fixed under the dashboard 2 of an automobile with a holding plate 3. An inlet 6 of the bag 4 is connected to a pipe route 14 through a three-way check valve 12, and pressurized fluid is supplied to the pipe route 14 from a source of pressurized fluid 24. A relief valve 20 and an adjustable throttle valve 22 are connected to a bypass pipe route 18 of the check valve 12. When a colision is detected, pressurized fluid is supplied to the bag 4 which in turn is inflated and expanded, and the driver of the automobile collides against the bag 4 which absorbs impact energy. When an impact energy is large, the pressure of a fluid in the bag 4 rises and opens the relief valve 20 and pressurized fluid is released through the throttle valve 22. Dampening is accomplished as kinetic energy is absorbed when pressurized fluid passes through the throttle valve 22.

Abstract: PURPOSE:To prevent short circuit between input terminals by providing a pair of input terminals and pressing a positive characteristic thermister against a protrusion on one input terminal. CONSTITUTION:A hollow tubular connecting member 41 projects integrally from the outer end face of a case cap 6 and a pair of input terminals 81, 82 are inserted into a T-shaped through hole 42 and bonded in place. A connection terminal 43 is connected electrically with the input terminal 81 through a conductive member 46 and connection terminals 43, 43 are connected electrically with a capacitor 47 through lead wires 60. A positive characteristic thermister 49 is held at a protrusion 54 of the input terminal 82. The positive characteristic thermister 49 touches only the protrusion 54 of the input terminal 82 by means of a clamp member 48 and does not touch the other input terminal 81. Consequently, there is no possibility of short circuit between the input terminals 81, 82. Since the positive characteristic thermister touches only one input terminal and opposes the other input terminal through a gap, short circuit can be prevented perfectly between the input terminals.
