Title: Linear servo system and method for detecting pole position
Inventor: KACHI MITSUYASU
IPC: H02P25/06
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To attain high resolution by employing a positional signal outputted from a linear scale, i.e., pulses of phases A and B, as a positional feedback amount and employing a speed data calculated through an interpolation/data generating means as a speed feedback amount for speed control. SOLUTION: A command voltage is applied through a position control means 11, a speed control means 12 and a current control means 13 to a linear motor 6 which is thereby driven and the shifted position thereof is detected by means of a linear scale 1. A position feedback amount for positional control employs a positional signal outputted from the linear scale 1, i.e., pulses of A, B pulses, whereas a speed feedback amount for speed control employs a data obtained by interpolating an analog sine and cosine signals outputted from the linear scale 1 through an interpolation/data generating means 14. Since positional resolution is not limited, speed and acceleration components can be detected with high resolution and a servo system excellent in response can be configured.

Abstract: PURPOSE:To achieve efficient and economical construction of prefabricated big space roof structure for such buildings as a gymnasium, a public hall, etc. by connecting curved central materials in a desired curvature with straightened materials in the tangential direction and by making them into corrugated frameworks by bonding the adjoining materials each other. CONSTITUTION:At the opposite ends of a curved central material 1, straightened end materials 2 are fixed, extending in the tangential directions, and an unit A is made thereby.

Title: Lightweight mortal
Inventor: TAKADA IZUMI
IPC: C04B14/22
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To obtain a lightweight mortal excellent in workability, free from the problem about working life and prevented from the generation of crack by mixing a granulated fired material consisting essentially of a specific glass powder with a calcareous raw material in the quantity of a specified range. SOLUTION: The lightweight mortal is obtained by mixing 4-50 pts.wt. granulated fired material having <=1.2mm particle diameter, 0.1-0.5kg/l weight per unit volume and <=10wt.% aggregate water absorptivity and consisting essentially of the glass powder to 100 pts.wt. calcareous raw material. Since the aggregate water absorptivity of the glass waste foamed material is controlled to <=10wt.%, the quantity of water to be added at the time of manufacturing the lightweight mortal having a viscosity suitable for coating work is almost the same as that at the time of manufacturing a regular mortal and the performance of the mortal after hardened is not largely changed.  Though the conventional mortal using a lightweight aggregate is large in water absorption and has problems such as freezing damage and the generation of crack, the lightweight mortal is small in water absorption, improved in troweling workability and has sufficient working life.
