IPC: G11B5/02
Filed: 1994-07-14
Abstract: PURPOSE:To make constitution of a magnetic field supplying element extremely com pact by forming coils on a bobbin consisting of a material having good thermal conduc tivity and forming a fin part for heat radiation at an extension part formed at the bobbin. CONSTITUTION:The flow of heat in this externally impressed magnetic field supplying element 7 is such that the temp. of the coils themselves rises sharply when a current flows into the coils. Heat conducts to the respective parts of the magnetic poles in contact and finally, the entire part of the externally impressed magnetic field supplying element 7 is heated and is made into a heating element. Then, the temp. rise over the entire part of the externally impressed magnetic field supplying element 7 is suppressed if the heat is released mainly around the coil body which is the cause for this heat. Namely, the coils are not directly wound around the magnetic pole part but the coil winding part 2 is formed in the bobbin part 1 formed out of a material having the good thermal conductivity, for example, Al. The fin part 3 for heat radiation is formed at the extension part of the bobbin part 1. The bobbin part is provided with a main magnetic pole through-hole 4, a magnetic field exit surface 5 and a return path 6, thereby, the heat generated in the coil winding part 2 is released into the air from the fin part 3.

Title: Reducing valve
Inventor: MORI MASAHARU
IPC: G05D16/10
Filed: 1983-09-02
Abstract: PURPOSE:To adjust surely the pressure of a reducing valve and to improve the safety by energizing a valve body in the direction, where the valve body goes away from a valve seat, and displacing the valve body against the spring force of a multiple spring in the direction where the valve body approaches the valve seat. CONSTITUTION:When air is discharged by inhalation and the pressure in a pressure chamber 89 is reduced, a valve body 82 is displaced in the direction, where the valve body 82 goes away from a valve seat 80, by double springs 88 and 88a, and a space 94 is generated between the valve seat 80 and one end part of the valve body 82, and high-pressure air in a valve chest 76 has the pressure reduced and is flowed into a flow passage 83. Flowed-in air is led to a air tube 7a through the pressure chamber 89 and a flow passage 90. When the pressure in the pressure chamber 89 rises by this flowing, the valve body 82 is displaced in the direction, where the valve body approaches the valve seat 80, against the spring force of double springs 88 and 88a to keep the airtight state. Even if one spring is faulty, the other is operated to supply a gas for inhalation continuously; and therefore, the safety is improved considerably by this double structure of the outside sping 88 and the inside spring 88a.
