Title: Ultrasonic measuring instrument
Inventor: TAKEMOTO SHUICHI
IPC: G01B17/00
Filed: 1990-01-17
Abstract: PURPOSE:To eliminate the influence of the long-distance propagation loss in a medium and to take a measurement over a wide range by providing a pulse- energy switch, and discriminating the intensity of a reflection echo, and switching the energy of an ultrasonic wave pulse automatically. CONSTITUTION:The pulse-energy switch 13 is provided which increases ultrasonic wave pulse generation energy when a reflection echo amplified signal 10 does not exceed a specific value even when the amplification gain value of a gain controller 11 reaches its upper-limit value. An ultrasonic wave pulse 15 is radiated toward a target 6 at a constant repetitive period and the reflection echo 8 is amplified; when the reflection echo amplified signal does not exceed the threshold value even if the amplification gain reaches the upper-limit value, the energy switch 13 outputs a pulse-energy switching signal 14 to switch the energy of a pulse generator 3, so the influence of reflection echo attenuation is eliminated even at a long distance to attain the measurement without reference to whether the measurement distance is long or short.

Title: Manufacture of sealed type lead-acid battery
Inventor: YOSHIDA TAKAMASA
IPC: H01M10/10
Filed: 1983-01-20
Abstract: PURPOSE:To prevent decrease of life caused with increase of height of electrode plates by discharging a battery after pouring a part of the total amount of electrolyte after assembling and charging after pouring the rest of electrolyte. CONSTITUTION:An electrode group assembled with fine glass fiber mats is inserted into a container and a part, 40% or less, of the total amount of electrolyte is poured in the container, and a battery is discharged. After pouring the rest of electrolyte, the battery is charged to form a sealed type lead-acid battery. The concentration of electrolyte poured before discharge is increased than that of electrolyte poured after discharge. The phenomena that when plates are high, water generating in a cathode during discharge diffuses upward and sulfuric acid generating during charge diffuses downward, and concentration of electrolyte is increased in the lower part is suppressed. Therefore, decrease of life caused with increase of height of electrode plates is prevented.

Abstract: PURPOSE:To reduce the capture rate of electrons inside an insulating film and to relax a hot-electron effect by a method wherein a hollow part is formed locally at a gate insulating film part, on a silicon substrate, which constitutes a MOS transistor. CONSTITUTION:A hollow part 4A is formed locally at a gate insulating film part 4, on a silicon substrate 1, which constitutes a MOS transistor. For example, a gate insulating film 4 is formed only in the central part between a silicon substrate 1 and a metal film 5; hollow parts 4A are formed on both ends of the gate insulating film. Alternatively, gate insulating films 4 are left on both ends between a silicon substrate 1 and a metal film 5; a hollow part 4A is formed in the central part. By this method, the capture rate of electrons inside the gate insulating films 4 is reduced; a hot-electron effect can be relaxed. Accordingly, it is possible to eliminate the problem related to reliability such as the increase in the hot-electron effect due to the high integration of a semiconductor.

SOLUTION: A plurality of circular-arc-like guide grooves 5 are formed on the underside of an outward flange 3a of a rotator main body 3, and in each guide groove 5, a steel ball 6 and a compression coil spring 10 always energizing the steel ball 6 on the shallow side of the guide groove are received. In this case, the compression coil spring 10 is formed so that the pitch P on the outer circumferential side is made larger than the pitch P on the inner circumferential side, hence the winding axis L is made into a circular-arc-shape coaxial with the rotator main body 3, and the radius of curvature of the guide groove 5 is nearly conformed to that of the compression coil spring 10.  Hereby the compression coil spring 10 is deformed in the same direction as the moving direction of the steel ball 6 along the guide groove 5, and a deflecting load is prevented from applying to the compression coil spring 10.
