Title: Capacitance type load cell
Inventor: MANABE ITSUO
IPC: G01G3/00
Filed: 1991-07-04
Abstract: PURPOSE:To reduce the warp of an electrode accompanying a change in the temperature of atmosphere. CONSTITUTION:In a capacitance type load cell detecting a change in a capacitance between first and second electrodes facing each other, as a change in a load metering signal, a first elastic body 15 is interposed between one side of the electrodes and the main body of the load cell and a second elastic body 16 is interposed between the other side of the electrodes and the main body of the load cell. When the temperature of atmosphere rises, an actuating force given by the first elastic body 15 weakens. Even when there is a difference in a linear expansion coefficient between materials and thereby the electrode 3a is warped, accordingly, the degree of this warp can be lessened in comparison with the one restrained firmly by a prescribed force irrespective of the temperature of the atmosphere and fluctuation of a load metering value accompanying a change in the temperature of the atmosphere can be reduced. Even in the case when the actuating force given by the first elastic body 15 weakens with the rise in the temperature of the atmosphere, moreover, occurrence of unstableness of the electrode 3a is prevented by restoration of the second elastic body 16.

IPC: G04B45/00
Filed: 1983-09-07
Abstract: PURPOSE:To enhance display effect, by allowing a clock body to repeatedly perform rising and falling motion by the swinging motion of a pendulum. CONSTITUTION:A swing rod 3 starts seesaw motion by starting the swinging of a pendulum. When the pendulum 7 swings to a direction separated outwardly from a support 2 as shown by a broken line, the gravity point of a clock body 5 moves to left and, because of these motions, balance is lost and the block body 5 is fallen. Contrarily, if the pendulum 7 moves inwardly, the gravity point of the clock body 5 moves to right and, because of these motions, balance is lost and the clock body 5 rises. Because the clock body 5 repeatedly performs rising and falling motion by the swinging motion of the pendulum 7 as mentioned, above visually pleasant effect is obtained and a pendulum clock unique as an ornament is obtained.
