Title: Friction welding method
Inventor: INOUE MASAHIRO
IPC: B23K20/12
Filed: 1979-12-18
Abstract: PURPOSE: To weld processed materials into a prescribed phase by frictional heat to facilitate friction welding, by rotating one of two processed materials and by compressing it to the other to stop it in a prescribed position.  
     CONSTITUTION: Chucks 4 and 16 and groove 10 of disc 6 are set to prescribed phases. Next, processed materials 3 and 15 are fixed acculately in the position to chucks 4 and 16, and rotation of motor 7 is transferred to shaft 1 through double clutch brake 9 to rotate it in a high speed. Next, cylinder 17 is operated to cause processed material 15 staying still to advance toward rotating processed material 3, and they are brought into contact with each other. Then, contact faces of processed materials 3 and 15 are heated and reach the welding temperature. At this time, connection of clutch 9 is broken and the brake is operated to reduce the speed of shaft 1. Next, rotation of torque motor 8 is transferred to shaft 1 through clutch 9 to rotate it in a very low speed. Next, cylinder 12 is caused to advance to link pin 11 to groove 10 of disc 6, and shaft 1 is stopped with a prescribed phase.

Title: Portable electronic device
Inventor: TANAKA TSUTOMU
IPC: G06K19/00
Filed: 1988-06-30
Abstract: PURPOSE:To cause the title device to input plural inputting amounts after summing the amounts so that complicated calculation can be eliminated by providing an arithmetic means which performs at least four operations when transcating amounts are inputted by using numeral and operation keys at the time of processing a transaction. CONSTITUTION:When a card owner inputs a transacting amount by using a keyboard 5, a control element 21 discriminates whether or not the amount is lower than the drawable limit of his bank account stored in a data memory 22. When the amount is lower than the limit, the element 21 subtracts the amount from the drawable limit of the account stored in the memory 22 and sets the subtracted result as a new drawable limit. The calculating function can be used when the owner inputs the amount through the numerals keys 12 and operation keys 13 and 16 of the keyboard 5. Therefore, plural inputting amount can be inputted when transacting amounts are inputted and complicated calculations can be eliminated when plural commodities are purchased.

Inventor: FUKUDA MASAHITO
IPC: B26B19/38
Filed: 1992-06-23
Abstract: PURPOSE:To provide an electric razor ensuring a low noise and comfortable use by fitting a resonant absorber within a body. CONSTITUTION:Four resonant absorbers 5 are provided at both sides of a motor 8 within a body 4. Each of the resonant absorbers 5 is a Helmholtz resonator having divisions 16 to divide the inside of the body 4 and form cavity sections 5b at space with the inner wall of the body 4, and lids 17 having neck sections 5a. In this case, the resonance frequency (f) of each resonant absorber 5 is set at 2450Hz, and corresponds to the frequency of the highest level sound among sounds having various frequencies contained in a noise generated due to the reciprocating motion of an inner blade 2. According to this construction, a noise generated due to the reciprocation of the inner blade 2 is absorbed by the resonant absorbers 5. This is because the air in the neck sections 5a vibrates, upon incidence of a noise to the cavity sections 5b, and sound energy is converted to heat energy, due to the internal friction of the sections 5a and thereabout.
