Abstract: PURPOSE:To realize a liquid jet head having high density nozzles by forming the nozzles in a thin film. CONSTITUTION:A layer 102 having a diffusion of high concentrated boron is provided to one side of a silicon substrate 101. If the other side of the silicon substrate is anisotropically etched against crystal axis by ethylendiamine, pyrocatechol and water mixture, and ink chamber 105 and a thin film portion 103 can be formed accurately. The ink chamber 105 and an ink feed passage- way 106 are formed between the silicon substrate and a processed glass substrate. An electrode 108 covered with an insulator layer is provided to the other side of the substrate. After the thin film portion 103 and a nozzle 104 are formed, the silicon substrate is heated and oxidized so that an insulator layer made of SiO2 is formed. When a certain voltage is applied between the diffusion layer 102 and the electrode 108, the thin film portion 103 as a part of the layer 102 is made flex by electrostatic attraction generated between the layer 102 and the electrode 108 so as to reduce the volume of the ink chamber 105 and to discharge the ink through the nozzle 104. Consequently, it is possible to realize a high density and multi-nozzle type liquid jet head.

Inventor: WAKEBE KEIZO
IPC: C02F1/48
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To bring about a physicochemical reaction and to increase the permeability into a biological diaphragm and the dissolution and absorption of the nutrient by bending a water pipe to pass water between magnets many times and increasing the passing points of the magnetic line of force to enhance the magnetic effect on the water. SOLUTION: When the water introduced from a water inlet 4 passes through a narrow water pipe 1 and then through the magnetic line of force of the N pole 6 and S pole 7 of a magnet 2, a physicochemical reaction is brought about by the MHD(magnetohydrodynamics) to finely divide the cluster of water, hence the water is turned into 'small water', and a high-density water is formed and discharged into a water supply and discharge pipe from a water outlet 5. In this case, the water pipe 1 passing between the magnets 2 is narrowed, and the pipe 1 is meanderingly bent to reciprocate the water between the magnets 2 many times. Consequently, the passing points of the magnetic line of force are increased, and a magnetic effect on the water is improved.

Abstract: PROBLEM TO BE SOLVED: To make a nut impossible to be pulled out by constituting a slipping- out preventive nut of the hexagonal part, the circular part and the small diameter part between both, and threading only the circular part inside surface in a through hole. SOLUTION: A slipping-out preventive nut is constituted of the hexagonal part 1a, the circular part 1b and the small diameter part 1c connecting both, and the through hole is formed as a screw hole 1d by threading only the inside surface of the circular part 1b. The circular part is threadedly engaged with the bolt end, the hexagonal part is fastened, the small diameter part is finally threaded, and only the circular part is left. The remaining circular part can be easily removed by an ordinary extractor such as a hexagonal socket and a hexagonal spanner since an external shape is cylindrical. The cylindrical part is not easily removed even if a special tool such as a pipe wrench is used since it is put in a calking state with a screw thread of a bolt at threading time.  When an outside end part large diameter hole of the cylindrical part is arranged, it becomes a cap for covering a nut, so that a tool cannot be hooked on the nut. Therefore, it is extremely difficult to loosen an existing nut.

Filed: 1990-04-13
Abstract: PURPOSE:To take a measurement with low noise and to phase difference by shifting the phase of the output signal of an oscillation circuit and eliminating the phase difference from a filter circuit. CONSTITUTION:When a phase difference is generated between the output of the oscillation circuit 1 and the filter 9, a phase difference detecting circuit 3 detects the phase difference between the output of the circuit 1 and the output of the filter 9 and inputs a phase difference signal to a transporting circuit 4. The circuit 4 shifts the output signal from the circuit 1 according to the phase difference signal so that the phase difference between the output of the circuit 1 and the filter 9 becomes zero, and outputs the signal to a V/I converting circuit 5. Then the phase difference between the output of the circuit 1 and the filter 9 is eliminated and the current-voltage characteristic and magnetic flux-voltage characteristic of DC-SQUID 6 can be measured. Consequently, the generated phase difference can be corrected automatically, so the measurement is performed with low noise and no phase difference at all times.

Title: Semiconductor device
Inventor: IMOTO SHINYA
IPC: H01L29/78
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To relax the field concentration on the ends of a conductive layer, without comparatively increasing the thickness of an insulation layer on the entire semiconductor substrate by partly forming a first conductive layer between a first and second insulation layers at the interface of diffused regions. SOLUTION: A second conductive layer 8 is formed on a second insulation layer 7 so as to extend from contact holes over a first conductive layer 6 and connected to this layer 6 through through-holes 10 formed through the second insulation layer 7. This allows the distances d1, d2 between the first and second electrode layers 6, 8 and semiconductor substrate 1 to be increased away from p-n junctions 3 to diffused regions 2. If hence a depletion layer 11 is formed around the p-n junctions 3 to result in generation of an electric field, the field concentration at the end of the second conductive layer 8 can be relaxed to improve the breakdown field intensities at the p-n junctions and the insulation layer beneath the end of the second conductive layer 8.
