Title: Production of pad for waxing device
Inventor: FUJII YUKIYOSHI
IPC: A47L13/30
Filed: 1990-05-11
Abstract: PURPOSE:To require no synthetic resin plate for reinforcing a sponge-like member, to decrease working processes and to easily form a pad by hardening a curable urethane resin for bonding a cloth-like fastener to the sponge-like member at normal temperature and obtaining a hardened plate for reinforcement. CONSTITUTION:A jig support 9 is projected on a support base 8 and fitted into a central hole of a sponge-like member 6. Under this state, while the support base 8 is rotated and the foundation 10 of the support base 8 is reciprocated to directions perpendicular to the rotation axis of the support base 8, a two-part urethane resin curable at normal temperature is extracted on the end face of the sponge like member 6 from an upper resin extractor 11 so as to draw a zig-zag circular arc thereon. Then, a circular cloth fastener 5 is pressed and bonded to a curable urethane resin layer 7 extracted on the sponge like member 6. In this case, the rotation of the support base 8 and the reciprocating movement are stopped. The jig support 9 passes through the central hole of the cloth fastener 5 so as to align with the center of the sponge like member 6. The curable urethane resin 7 is hardened in short time to obtain a thin hardened plate.

Filed: 1977-10-13
Abstract: PURPOSE: To increase safety and reduce the weight of the device without enforcing parts by electrically detecting the unbalanced vibration of blowing vanes and automatically stopping the motor through breaking the circuit of the motor.  
     CONSTITUTION: A rotary shaft 8 is supported by a ball bearing 12 in its middle. A resistance wire strain gauge 16 as an electric detector is buried in the cylindrical metal 15 along the axial direction.

Above deformation effects tension and pressure upon the resistance wire strain gauge 16 to increase or decrease the resistance value of the gauge 16. This resistance change is turned into electric change to operate a relay 19, cutting the power to the motor 4
