Title: Estimating method for acoustic radiation state
Inventor: TAKATSUKI KIYOAKI
IPC: G01H3/00
Filed: 1985-11-14
Abstract: PURPOSE:To estimate the directivity of sound and a sound pressure level at long distance by measuring the speeds and phases of nearby particles nearby a vibration surface and knowing the vibration mode of the vibration surface. CONSTITUTION:Signals of three channels from moving microphones 1 and 2 for sound pressure measurement at two nearby points and a microphone 3 as a phase reference fixed at an optional constant point in the sound field of the acoustic vibration surface 4 are sampled at the same time through noise meters 5, 6, and 7 and low-pass filters 8, 9, and 10. Those are processed by the fast Fourier transformation of a computer 11. Namely, the frequency response function between a phase reference signal and two nearby points is calculated and a phase error base upon phase characteristics of microphones 1 and 2 used at the two nearby points is corrected to fix the phase of sound pressure at the two nearby points. Thus, the sound pressure and phase at the two nearby points which are found at specific plural frequencies are used to find the particle speed and phase from a specific expression.

Title: Dispersing agent for excavation slurry and excavation slurry using the same
Inventor: SUMIDA MITSUTERU
IPC: E02D5/18
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain a dispersing agent which give slurry having wall-making property from a granule ingredient alone of excavated soil without requiring a slurry-making material by composing it of a poly(meth)acrylate salt (copolymer) and specifying its wt. average mol.wt. SOLUTION: A poly(meth)acrylate salt (copolymer) has a wt. average mol.wt. of 10,000-14,000 and is preferably a monovalent salt (e.g. a sodium salt). The poly(meth)acrylate salt (copolymer) having a wt. average mol.wt. of 10,000-14,000 and soil constituted of a granule ingredient, preferably not larger than 10μm are compounded to form excavation slurry. This excavation slurry can maintain its low viscosity owing to the high dispersing function of the dispersing agent even if the specific gravity of the slurry becomes high, resulting in improvement of excavation efficiency, transportation efficiency and soil-sand separation efficiency. Besides, as the excavation slurry is not deteriorated, occurrence of a large amount of waste sludge is prevented even when it is circulatively used in an underground continuous wall method.

IPC: H05K3/46
Filed: 1991-10-04
Abstract: PURPOSE:To provide a low cost multilayer printed wiring board which does not need screwed components and the like for fixing structural members and has a simple construction. CONSTITUTION:Theremoplastic film 1, 2, 3 and 4 are laminated and external heat and pressure are applied to the films to fix some of or all of structural members such as nuts 5 and reinforcing members which are held between the thermoplastic films 2 and 3. Because of the characteristics of thermoplastics, the board shows plastic deformation easily. Therefore, the board is deformed along the profile of the structural members to hold the structural members securely between the layers. With this constitution, it is not necessary to attach the structural members to the wiring board afterwards by using separate components such as fixing screws and nuts and the manufacture process and the construction of the interconnection board can substantially be simplified.

Title: Overcurrent protective device
Inventor: ISHII KAZUHIRO
IPC: H02H3/08
Filed: 1989-10-04
Abstract: PURPOSE:To suppress generation of heat and to reduce the size by bypassing the excessive portion of secondary current of a current transformer through a switch. CONSTITUTION:A load current L is detected through a current transformer 4, rectified through a rectifier circuit 5 and smoothed through a smoothing capacitor 12. When the value of smoothed load current exceeds a predetermined level, a switch 10 functions through a time limit circuit 9 and the contact of a circuit breaker 2 is tripped by a trip coil 3. On the other hand, voltage across the smoothing capacitor 12 is compared with the voltage from a reference voltage generating circuit 13 by means of a comparator 14. When the reference voltage is exceeded, transistor 15 is turned ON and held in ON state until the voltage across the smoothing capacitor 12 drops below the reference voltage, and thereby the output from the rectifier 4 bypasses the control power source.
