Title: Structure of water-barrier material and its underground insertion
Inventor: HASHIMOTO ISAO
IPC: E02D31/02
Filed: 1991-03-29
Abstract: PURPOSE:To easily insert a water-barrier material by recessively providing a water- passing groove for water passing in the longitudinal direction and installing a water- absorptive material in the state to cover the water passing groove on an impermeable linear body. CONSTITUTION:A water-barrier material 1 is formed of an impermeable linear body 11 provided with a large number of water passing grooves 13 in the longitudinal direction and a water-absorptive filter layer 12 installed in the state to cover the grooves 13. Drilling mud 21 is sucked up through the grooves 13 by way of inserting the water-barrier material 1 by several meters in the longitudinal direction on the upper part of a trench 2 filled with the drilling mud 21 and giving negative pressure on the head end of the grooves 13. Then, the water surface of the drilling mud 21 inside of the grooves 13 becomes higher than the water surface inside of the trench 2 by DELTAh by a suction force of the negative pressure and increases the apparent weight, and the water-barrier material 1 is inserted in the trench 2 by the dead weight. Thereafter, soil particle part contained in the drilling mud 21 and others is absorbed toward the outside of the filter layer 12 through the filter layer 12 and a soil particle layer is constituted, and it displays its function as a protective layer for the water-barrier material 1 and resists against deformation and damage after insertion.

IPC: G01R31/02
Filed: 1983-07-22
Abstract: PURPOSE:To discriminate whether an isolated pulse or plural pulses are inputted from a signal change detector by using a memory whose write and read are executed asynchronously with each other. CONSTITUTION:A logical level detector 11 detects what state a signal inputted to a terminal 100 is in, i.e. logical level ''H'' or ''L'' or open state, and the signal change detector 22 outputs a 1-pulse write signal to the memory 23 when the input signal enters a logical level state. Further, a signal indicating that the signal having the logical level is inputted from a terminal 25 closes a switch 16 to make a connection between a tone oscillator 15 and a speaker 17. The signal inputted to the memory 23 is outputted from the memory 23 at intervals of T seconds long enough to listen by the ear from a readout signal generated by a readout clock 24 which operates asynchronously with write pulses; and the read signal is converted by the tone oscillator 15 into a sound to input to the speaker 17.

Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To obtain a probe needle that is capable of probing accurately, has a simple structure, and can be easily manufactured by performing the probing to a probe pad at a fixed needle side and preventing it from being made at a movable needle side. SOLUTION: When a pressure is applied to a guide plate 7, a probe needle 11 is lowered against the resilient force of an elastic material 8 and contacts the lead wire of a semiconductor element 22 and a probe pad on a printed circuit board 21. At this stage, the probe needle 11 rises along with an outer cylinder, so that no load is applied to the printed circuit board 21. Further, when a pressure continues to be applied to the guide plate 7, the upper edge of the probe needle 11 contacts the probe pad being provided at the guide plate 7 and is loaded, a movable needle retreats, and a load is applied onto the printed circuit board 21.  Therefore, the probe needle 11 does not apply a load to, for example, the lead wire of a semiconductor element 22 on the printed circuit board 21 when a pressure starts to be applied to the guide plate 7 and can be brought into contact with, for example, the lead wire with an improved balance, thus achieving an inspection accurately.

Title: Composite sensor
Inventor: HANJI MOTOYASU
IPC: G01P15/18
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To detect angular speed with high precision as well as acceleration. SOLUTION: An excitation electrode is formed at branch parts A2 and A3. A detection electrode is formed at branch parts A4-A7. A5 and A7 are tilted. The excitation electrode is applied with AC voltage e for stretching vibration of A2 and A3 with amplitude in Y-axis direction. Thus, A1 is brought into bending vibration with amplitude in Y-axis direction parallel to an X-Y plane while A4-A7 brought into bending vibration with amplitude in X-axis direction parallel to the X-Y plane. With rotation around the Y-axis, Coriolis force allows bending vibration of A4-A7 with Z-axis direction component, with a voltage signal corresponding to angular speed obtained from the detection electrode or A4 and A6.  With acceleration acting in Z-axis direction, a bending vibration which starts with torsion phenomenon due to inertia takes place at A5 and A7, providing a voltage signal corresponding to the acceleration from the detection electrode of A5 and A7.
