Title: Permeability measuring device of magnetic substance
Inventor: KAKEHI AKIRA
IPC: G01R33/12
Filed: 1979-11-29
Abstract: PURPOSE: To ensure a simple measurement for the complex permeability of a thin plate type sample, by supplying the AC to the coil having such a form as to enclose the cross section of the magnetic substance and then detecting the component of the same phase and a 90°-advanced phase to the application AC of the electromotive force which is induced to the coil.  
     CONSTITUTION: The electromotive force is induced with application of the AC to the constant current of the air core coil. When the magnetic substance is put into the air core coil, the inductance varies. The measurement is possible for the permeability since the electromotive force of the air core coil can be measured previously. The Wμ"Sα can be obtained from the electromotive force of the same phase as the current applied, and the Wμ'Sα can be obtained from the electromotive force of the 90°-advanced phase respectively. Here W is the angular frequency of the application current, S is the cross-sectional area of the magnetic thin film to be measured, and α is  the coefficient showing the application magnetic field which is decided by the form of coil. These  factors are all known, and thus the permeabilities μ' and μ" are shown by the equations I and II  each when the voltage having the same phase as the current is referred to as l 1  and the voltage of  90°-advanced phase is as l 2  respectively. Accordingly, the complex permeability μ can be  obtained as μ=μ'+jμ". As a result, the complex permeability can be measured simply for a thin  plate type sample by detecting both l 1  and l 2 .

Title: Lens for bar code irradiation and bar code reader
Inventor: MIZUTANI YUICHI
IPC: G06K7/10
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To output irradiation light, with which both a bar code near a read port and a bar code away from the read port can be surely read, irradiated and recognized for an operator as well, without expansion or cost-up concerning a large depth bar code reader. SOLUTION: Irradiation light 1 emitted from an emission plane 54a on a 1st lens part 30a of lens 30 for bar code irradiation is not spread. Therefore, since the irradiation light L1 is not almost spread even at the position of bar code away from a read port 22 of bar code reader 4 for several 10 cm, the operator of bar code reader 4 can recognize it as the line of red light and can exactly aim at the distant bar code. Irradiation light L2 emitted from an emission plane 54b on a 2nd lens part 30b is gradually spread and since that light is spread over all at the part of read port 22, the bar code near the read port 22 can be surely read. Further, since a light source is not increased, expansion or cost-up is not invited.

Title: Vacuum cleaner
Inventor: SOEJIMA MASAKUNI
IPC: A47L9/28
Filed: 1989-06-16
Abstract: PURPOSE:To prevent a temperature rise to enhance the safety by providing, one the blow-off side of an incorporated fan motor, a temperature protector made of temperature sensing ferrite, which detects a temperature of blow-off air so as to open and close an opening formed in the body of a vacuum cleaner. CONSTITUTION:A temperature protector 8 is mounted in an opening 9 formed in a body 1, corresponding to an blow-off passage of a fan motor chamber 5, and has a temperature sensing ferrite plate 11 which is removably coupled to a permanent magnet 10 secured at the periphery of the opening. When a paper bag 2 is fully filled with dust during operation, the volume of air sucked from a suction member decreases so that the temperature T of blow-off air becomes high. If T=T0, the magnetic force of the temperature sensing ferrite plate 11 disposed in the blow-off passage decreases so that the binding force between itself and the permanent magnet 10 decreases. Accordingly, it is moved downward by the urging force of a spring 12, resulting in opening of the opening 9 so that the blow-off air flows through the opening 9 and is then discharged to the outside of the body 1. Further, when the temperature sensing ferrite plate 12 is moved, a switch 15 is actuated so that a power source for the fan motor 4 is turned off to interrupt the operation of the vacuum cleaner.
