Title: Yoke structure of pm type stepping motor
Inventor: MIYAZAWA HIROSHI
IPC: H02K37/14
Filed: 1989-05-31
Abstract: PURPOSE:To prevent bending of tooth by coupling between adjoining pole teeth of inner and outer yoke through bridges thereby compensating mechanical strength of pole tooth even for micro step angle. CONSTITUTION:A plurality of pole teeth 32 are arranged on an outer yoke 21 and a bridge 34 is surrounding the pole teeth at the root section of the outer yoke 21. A bridge 35 is similarly arranged in an inner yoke 22 at the root section of pole teeth 33. Since the bridges 34, 35 are arranged at the root section of the pole teeth, bending of tooth is prevented through compensation of magnetic saturation and mechanical strength at the root section of the pole tooth. By such arrangement, mechanical strength of thinned pole tooth for micro step angle can be compensated and bending of tooth is prevented, while furthermore magnetic saturation of pole tooth is prevented, gap accuracy is improved and flux is utilized effectively, resulting in a high torque motor structure.

Title: Resin composition for bonding fiber-reinforced sheet and method for reinforcing concrete structure
Inventor: NAKAJIMA JUNICHIRO
IPC: E04G23/02
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To obtain an epoxy resin composition used to bond fiber-reinforced sheets, which composition comprises an epoxy resin which develops a specified or lower compressive modulus after being cured, desirably, an epoxy resin of a two-package type. SOLUTION: This composition comprises an epoxy resin which develops a compressive modulus of below 980 N/mm2 after being cured. This can be realized by adjusting the crosslinking density, epoxy equivalent, and structure of the epoxy resin, or by adjusting the active hydrogen equivalent of a curing agent in a two-package epoxy resin. The compressive modulus can be heightened by heightening the crosslinking density, and it can be lowered by lowering the crosslinking density. The compressive modulus can be lowered by heightening the epoxy equivalent, and it can be heightened by lowering the epoxy equivalent.

Abstract: PROBLEM TO BE SOLVED: To provide a resin sealing device which is capable of easily and accurately adjusting an injection pressure with the improvement of maintenance services and also is of a small size as a whole and less costly. SOLUTION: A drive pressure is applied to an air hydrobooster 6 from a compressed air source 11, and then is applied to each of multiplunger drive cylinders 5 from sending side piping 7a.
