Title: Detector for piston stroke
Inventor: TERAJIMA TOSHIO
IPC: G01B7/00
Filed: 1981-11-13
Abstract: PURPOSE:To permit accurate detection by detecting the extent of movement of a piston electrically with a differential transformer contained in the piston thereby eliminating the need for separately providing detectors, making the detector compact, obviating failure by the impact, etc. from the outside and making the detector virtually free from thermal influence. CONSTITUTION:When pressurized oil is supplied through the port 13 of a cylinder 1, a piston 2 is moved leftward, and a core 7 mounted to a piston rod 3 moves by the same extent. The extent of the movement is drawn out in the form of an electric signal from a differential transformer coil 6 to a detector. Conversely, when the piston 2 is moved rightward by supplying the pressurized oil through the port 14 of the cylinder 1, the similar operations take place. It is equally well to reverse the installation of the core 7 to the rod 3 and the installation of the coil 6 to the cylinder 1. A pneumatic cylinder or the like other than an oil hydraulic cylinder may be used for the cylinder 1.

Title: Method of ground impregnation construction
Inventor: SHIMADA SHUNSUKE
IPC: E02D3/12
Filed: 1992-06-16
Abstract: PURPOSE:To consolidate the ground quickly and simply by simultaneously impregnating liquids having different pH from vertically different filler holes, interrupting the impregnating liquids by seals and ejecting and impregnating the liquids into the ground separately independently. CONSTITUTION:A multiple impregnating pipe X is inserted into the ground, and installed while the positions of the filler holes 3 of the impregnating pipe X are displaced in the axial direction of the impregnating pipe X. Impregnating liquids having different pH are blended so that pH displays the alkaline side from the upper filler holes 3 and the acidic side from the lower discharge openings. The impregnating liquids impregnated from the different filler holes 3 are mixed in voids in the periphery of the impregnating pipe, and gelation is promoted and seals are formed centering around spaces among the upper and lower filler holes 3 suddenly. The impregnating liquid on the acidic side having the long gelation time is moved upward along the voids in the periphery of the impregnating pipe X, and brought into contact with the impregnating liquid on the alkaline side and the seals of gelation, thus accelerating gelation. The seals are reinforced, and the inside of the peripheral ground is impregnated with the impregnating liquids having different pH separately independently, thus positively consolidating the ground.

Abstract: PURPOSE:To increase the productivity, by providing grooves on a substrate forming a thin film element, burying a conductor in the grooves to make connecting terminal, and connecting a conductor film for thin film element and an external lead via the connecting terminal. CONSTITUTION:Grooves 12 to bury connecting terminals are formed on a substrate 11 with mechanical processing or chemical etching. A number of grooves 12 are formed on the substrate 11 corresponding to pitches formed with thin film elements. When the insulation resistance of the substrate 11 is small, after the insulation film made of SiO2, Al2O3 and the like is formed on the entire surface including the grooves 12 with vapor deposition or sputtering, a connecting terminal conductor 14 such as Cu, Al and Au is formed in the groove 12. After forming a thin film element 2, it is cut off and processed into individual floating sliders and then leads 5 are connected. Two leads can be led from one connecting terminal 14, by forming a conductor separation groove 13 with a depth slightly deeper than the thickness of the terminal 13, i.e. the depth of grooves. Thus, the productivity can be increased and the performance is made stable.

Filed: 1990-07-09
Abstract: PURPOSE:To enable a record over a long time by a camera by one time of battery charge by suppressing current consumption consumed by a referring means by using at least one of an output signal from on AGC circuit and the output signal from an iris controlling circuit. CONSTITUTION:The luminance information of an object is read in a CPU 9 by the detecting output of the AGC circuit and the iris controlling circuit, and a practical minimum S/N ratio is secured by the operation of either an AGC circuit 4 which feedback-controls an emitted light from an illuminating means 12 to a necessary minimum value or an iris controlling circuit 17. Also, the illuminating means 12 is not operated in the range of the illuminance of the object in which the output level of a camera can be constantly a standard output. When a power supply to the illuminating means 12 is started according to the output signal in the area under the illuminance of the object, the practical minimum S/N can be secured. Also, the light emission of the illuminating means 12 is operated in the possible area in which the standard output can be obtained, and the consumption of a battery 15 is reduced. Thus, a workable time can be long, and the record over the long time can be attained, by one time of the charge of the battery 15.
