Title: Method and device for measuring irregularity between axial centers during rotation
Inventor: YOSHIDA TOSHIKAZU
IPC: G01B7/312
Filed: 1980-09-01
Abstract: PURPOSE:To make the simple and easy measurement of the irregularity between axial centers while keeping a rotating shaft rotating possible by disposing electromagnetic coils near the end of the revolving shaft and measuring the values of the inductive currents changing in accordance with the distances between both. CONSTITUTION:The measurement of the irregularity between axial centers is made possible irrespectively of the presence or absence of rotation by detecting the change in the distance between the end of a rotating shaft and electromagnetic coils by the change in the inductive current by the electromagnetic coils. For example, an electromagnetic primary coil 7 and a secondary coil 8 are mounted in a spacer 6 for shaft joint in a position near the end face of a rotating shaft 1 and away from the axial center by using a holder 15. When AC is flowed to the primary coil by way of a conductor 13, a brush 14, a primary electrode 10, a lead wire 9, etc., the voltage corresponding to the distance between the coil and the shaft end is induced in the secondary coil. If a notch is given to the electrode 11 of the secondary coil, the rotating position of the coil is known, and the irregularity of the axial centers is easily measured.

Abstract: PURPOSE:To increase the withstanding voltage of an element without changing supply voltage by forming an impurity region having concentration lower than the concentration of an impurity region having low concentration and an impurity region having high concentration between both of the impurity regions. CONSTITUTION:An n<+> diffusion layer 9 and an n<-> diffusion layer 8 reaching to a section just under a gate electrode are formed to a p type Si substrate 1. Low impurity concentration is shaped in the vicinity of boundaries among the layers 9 and the layer 8 and high impurity concentration higher than said concentration at a point near by a channel section in impurity concentration distribution in the layer 8. Accordingly, a power electric field region is divided into two in the vicinity of a boundary between the layer 9 and the layer 8 at a drain end and in the vicinity of a boundary between the layer 8 and the channel section, and maximum field strength is lowered, thus increasing the withstanding voltage of an element by 1-3V.

IPC: B63C11/02
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent unnecessary power consumption by putting a water detecting means in an inactive state when shifting a mode to an altitude measuring mode. SOLUTION: A mode selecting means 2 selects a clocking mode in an initial state, and a display selecting means 7 selects time data from a clocking functional means 4 and displays time on a display means 8. When an altitude mode shifting switch is operated, a switch control circuit 11 shifts the mode selecting means 2 into an altitude measuring mode. An altitude measuring means 5 starts action upon receiving an altitude measuring mode signal and outputs altitude data. The display selecting means 7 also shifts its output to altitude data, and the display means 8 displays altitude measured data. In the altitude measuring mode, a water detecting means 3 is put in an inactive state, and a water depth measuring means 6 does not act.  When shifting from a water depth measurement preparation mode to the altitude measuring mode, an alarm means 9 gets the display means 8 to make an alarm display.
