Title: Micro hardness meter
Inventor: KIMURA SHIYOUZOU
IPC: G01B11/02
Filed: 1982-05-24
Abstract: PURPOSE:To enable the measurement of hardness automatically with good accuracy by making effective use of the phenomenon in which, when coherent light such as laser light is irradiated to the recess of a sample, the reflected light scatters at the edge thereof. CONSTITUTION:Laser light 1 (L1) is bent on one part (L2) by a half mirror 2 and is passed on the other (L4) through the mirror rectilinearly. The bent laser (L2) is further bent by a half mirror 3 and the light (L3) thereof is irradiated onto the test surface of a sample 4 on sample receiving bases 5, 6. The laser light advancing rectilinearly is irradiated perpendicularly to a stationary reflecting mirror 9 attached to a fixing part, and the reflected light thereof is made incident again to the half mirror at the same optical axis, by which the light is bent rightward so as to join with the reflected light from the sample receiving bases. An interference phenomenon is induced in the confluence of both beams of the reflected light as the reflected light from the base 5 displaces. The interference fringes shift by each one pitch in correspondence to the displacement rate of the sample receiving bases and is inputted to two photoelectric transducers 15, 16. The interference fringes are then counted with a counter 20 and are displayed 21.

Title: Tripod tuning fork oscillator and angular speed sensor
Inventor: ASANO SHOGO
IPC: G01C19/5607
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To realize a small high sensitivity sensor by employing a tripod tuning fork structure where triangular prisms on the opposite sides and a central quadrangular prism are arranged in row thereby facilitating formation of electrode and wiring. SOLUTION: Triangular prisms A, B and a quadrangular prism C are excited in the in-plane direction as shown by an arrow 21 on Fig. (a). When a voltage is applied alternately from a drive electrode E to respective electrodes 4a, 5a, 6a on the exciting shaft A as shown on Fig. (b), the part 23 contracts while the part 24 elongates because inner charges of the exciting electrodes 4a, 5a, 6a on the exciting shaft A are inverted from + to - if a voltage having polarity shown on Fig. (b) is applied. Consequently, the exciting shaft A flexes in the direction of arrow 19 and a Coriori detecting shaft C also flexes in same direction because of the tuning fork structure of the exciting shaft A and the Coriori detecting shaft C. Similarly, the Coriori detecting shaft C flexes in the direction of arrow 20 because of the tuning fork structure of the exciting shaft B and the Coriori detecting shaft C and thereby the amplitude is amplified. Since rotational moment can be canceled through the tripod tuning fork structure upon occurrence of Coriori, oscillatory loss can be minimized.
