Title: Light scanning type position deviation detector
Inventor: MIWA TOSHIYUKI
IPC: G01B11/24
Filed: 1992-07-09
Abstract: PURPOSE:To detect how much the line-shaped mark of an object to be measured deviates for a specific reference position. CONSTITUTION:An object 40 to be measured has a symmetrical line-shaped mark 40a. A position deviation operation circuit 17 is added to a light scanning type displacement meter 16. The light scanning type displacement meter 16 scans light beams a for an object 40 to be measured while being crossing the line-shaped mark 40a by a scanning mirror 5, obtains signals V1 and V2 corresponding to an incidence position by applying reflection light to a position detection element 8, and then obtains a displacement amount signal L=(V1- V2)/(V1+V2) corresponding to the displacement of a distance Lb from the object 40 to be measured by operation. The position deviation operation circuit 17 judges whether the displacement data of the line-shaped mark 40a is symmetrical or not based on the displacement amount signal L and then outputs a position deviation signal Sp with a sign and size corresponding to the degree of asymmetry.

Title: Variable speed sensor
Inventor: TOOBUJIYOON CHIYUUEN
IPC: H01H35/14
Filed: 1990-07-10
Abstract: PURPOSE: To secure safety of an occupant by a sudden speed reduction of an automobile by constituting a speed change sensor of an inertia member moved by inertia force, a guiding means of the inertia member and a spring means to stop the inertia member in a constant position on the guiding means. CONSTITUTION: When an automobile is forced to perform a sudden speed reduction, a steel ball 46 is pressed under a device by sudden pressure. This force pushes a blade 22 downward, and contacts it with a blade 24. When this press is insufficient, the blade 22 is supported by the blade 24, and stops a movement of the ball 46. In the case of a strong press, since the blade 24 cannot support a press of the ball 46, the ball 46 moves up to a bottom part of a housing 18. Since pressing force of the ball 46 is reduced by resistance by such a blade 24, damage of the housing 18 by a collision is prevented. When the blades 22 and 24 contact with each other, an electric current flows to an actuator 42, and an air bag suddenly swells.

Title: Vibrational cutting device
Inventor: KAWAMOTO SHIGERU
IPC: B23B37/00
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To stably maintain large vibration by adapting a cutting blade to be torsionally displaceable around an axis parallel to a cutting direction with cutting resistant. SOLUTION: Movement of chip 4 held to a tip part of a tip arm 3 is a combination of rotational movement due to two rotational center shafts 5, 6 and which movement becomes movement on an ellipse in a vertical surface with respect to a cutting direction. That is, the chip 4 can freely vibrates in the vertical surface with respective to the cutting direction due to cutting resistance caused in the chip 4 and as the damping of the vibration is not restrained, the chip has relatively large amplitude. Whereby, the chip caused by the cutting is divided into short and it will not entangle on the tip 4. On the other hand, tip 4 has high hardness with respect to a cutting direction and chatter vibration may be restrained and diameter accuracy may be improved.

Title: Lightweight thermoplastic resin
Inventor: TAKAHASHI SEITARO
IPC: B29B7/90
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To lighten a thermoplastic resin and obtain a product excellent in a chemical resistance by a method wherein inorganic foamed particles, within each of which an infinite number of minute closed cells are filled in the same material, are employed as a filler and, in addition, the particle diameter of the inorganic foamed particle is set to be a specified value or less. SOLUTION: Each inorganic foamed particle is manufactured by granulating a porcelain raw material consisting of a silicon oxide, an aluminum oxide, a calcium oxide, a magnesium oxide, a potassium oxide and a sodium oxide, added with small amount of a foaming agent and then firing at an elevated temperature of 1,350 deg.C with a rotary kiln. As a manufacturing method, inorganic foamed particles mixed with pellets made of thermoplastic resin such as PP or the like are kneaded under heat with a kneaded. In this case, the diameter of the inorganic foamed particle is set to be 1.0 mm or less in order to prevent the particle from being crushed. Concretely, if the particle diameter exceeds 1.5 mm almost all the inorganic foamed particles are crushed at their kneading, resulting in increasing the bulk specific gravity of the thermoplastic resin due to their crushed fragments.
