Abstract: PURPOSE:To precisely measure horizontal, vertical and oblique directions by dividing a measuring instrument body into two parts, bendably connecting them, and measuring the quantity of displacement at a bent part through a displacement gauge or an angle gauge. CONSTITUTION:A measuring instrument body 1 is divided into a body piece 1A and an introducing piece 1B, and both the pieces are bendably connected through a shaft 2. A displacement gauge 7 is set inside the body piece 1A, and issues a signal to show the quantity of displacement according to the bending angle of the pieces 1A, 1B at the time of their bending, and transmits the above signal to a ground station through a cable K. A guide pipe is provided in a boring hole, and the body 1 is inserted to the bottom of the guide pipe. As the body 1 is drawn up to each measuring point for predetermined spaces from the above bottom, measurement value shown by the displacement gauge 7 is looked with eyes at the measuring point and inputted into a personal computer. At the end of the measuring process, the body 1 is rotated as much as 180 deg., and inserted to the bottom of the pipe again, and then the measurement is similarly carried out. Thus data obtained by the measurement at each point in positive and negative directions are accumulated, and the computation is carried out on a basis of initial measurement value to determine the quantity of displacement of the ground.

Title: Method and device for vacuum vapor deposition
Inventor: FUKUYAMA RIYOUICHI
IPC: C23C14/54
Filed: 1980-12-24
Abstract: PURPOSE:To improve vapor deposition efficiency considerably by applying potential of reversed polarity to targets while ionizing the vapor source atoms scattering from a vapor source material in a vacuum atmosphere. CONSTITUTION:The inside of a bell-jar 1 is maintained in a vacuum state, and an evaporating tray 6 and a vapor source material 2 are heated by conducting electricity to filaments 5. When positive high potential is applied to a grating 7, the thermions from the filaments 5 impinge vigorously upon the atoms 2b from the material 2 and while the atoms 2b are positive-ionized, they scatter to the outside of the grating 7. At this time, targets 3 are applied with negative potential and therefore a potential gradient is formed in the bell-jar space between the targets 3 and the grating 7, and the positive-ionized atoms 2b scatter toward the targets 3 of reversed polarity along the potential gradient. Thereby, almost all the atoms 2b are stuck on the surfaces of the targets 3, and the efficiency of vapor deposition is improved considerably.

Title: Transistor control circuit
Inventor: IIZAWA TAKAHARU
IPC: H03K17/08
Filed: 1990-07-10
Abstract: PURPOSE:To prevent short-circuiting from being generated by turning on simultaneously by providing a second control transistor to turn off a first driving transistor while turning on the same first driving transistor by a first control transistor. CONSTITUTION:When turning on a first driving transistor PT1 by a first control transistor Tr1, switching timing is set to a second control transistor Tr2 so as to obtain a period for turning off the transistor PT1. Therefore, even when the ON operation control is executed by the transistor Tr1, the transistor PT1 is not turned on. During this period, a second driving transistor PT2 is controlled to be turned off by a third control transistor Tr3, and after this transistor PT2 is completely turned off, the ON operation inhibitation of the transistor PT1 by the transistor Tr2 is canceled. Thus, the transistors PT1 and PT2 can be prevented from being simultaneously turned on.
