摘要： PURPOSE:To provide a heating element capable of stably sliding paper without catching it by forming an enameled layer on the outer surface of a cylindrical tube or making the cylindrical tube itself with glass to make the outer surface coming into contact with a roller smooth so as not to have recesses and projections or pinholes. CONSTITUTION:A resistor layer 14 formed on the inner surface of a cylindrical tube 11 generates heat by current supplied from an electrode connected to the resistor layer 14. The heat of the resistor layer 14 is conducted to an enameled layer 12, the cylindrical tube 11, and an enameled layer 13 formed on the outer surface of the cylindrical tube 11 in order. At the same time, a sliding surface 16 of the enameled surface 13 on the outside of the cylindrical tube 11 and a roller 15 are rotated to transfer paper 17, and since the paper 17 is heated, toner image is melted and fixed on the paper 17.

摘要： PURPOSE:To make it possible to completely prevent solder melting resistance from deteriorating when circuit substrates, etc., are packaged in the flow method, by forming a variable resistor with the entire surface of the primary electrode exposed to the outside and the secondary electrode which is an Ni- plated layer partly covering the surface of a resistance element. CONSTITUTION:An edge surface primary electrode 4, a resistance surface primary electrode 3, back surface primary electrode 5 are, respectively, provided on one end part of an insulated substrate 1. Furthermore, a resistance element 2 is formed by printing, etc., overlapping part of the resistance surface primary electrodes 4 on one side of the insulated substrate 1. The entire surface of the primary electrodes 3, 4, and 5 and a part of a resistance element 2 are covered by an Ni electrode 6 prepared by plating, and, further, its outside surface is covered by a Sn/pb alloy layer 7. Because the entire surfaces of the primary electrodes which tend to undergo silver melting are covered by the Ni metal-plated layer, when packaging is made by the flow method, connecting reliability is improved. Although a rotating type variable resistor is explained, even in the case of a variable resistor of the linearly sliding type, there is no difference in the action and effects.

摘要： PROBLEM TO BE SOLVED: To provide a rotation speed sensor capable of stabilizing an output signal by preventing current flowing through a magnetoresistive element from flowing to a magnet via an Si substrate even when the resistance of the Si substrate drops at high temperatures.
SOLUTION: The rotation speed sensor has an insulating layer 27 formed of tape made of polyimide resin disposed between the magnet 26 and the Si substrate 22 having the magnetoresistive element 21. The insulating layer 27 formed of the tape made of polyimide resin prevents the current flowing through the magnetoresistive element 21 from flowing to the magnet 26 via the inside of the Si substrate 22.

摘要： PROBLEM TO BE SOLVED: To obtain a number-of-revolution sensor in which a connecting layer is not disconnected even when the sensor is oscillated strong by folding the connecting layer to be electrically connected to a base terminal of a base in a direction opposite to a film of a magnetoresistive element and folding the film to trace the folding of the connecting layer. SOLUTION: After a face of a magnetoresistive element 21 at the opposite side to where an Si substrate 22 is provided is bonded to a connecting layer 24, the connecting layer 24 and a film 23 are folded along a fold hole 25 of the film 23. A magnet 27 is secured to a lower part of a base 28, and then the Si substrate 22 is bonded to a lower face of the magnet 27. The connecting layer 24 is registered to a position of a base terminal 29 of the base 28 and soldered. The connecting layer 24 is folded to be electrically connected to the base terminal 29 of the base 28 in a direction opposite to the film 23 of the resistive element 21, and moreover the film 23 is folded to follow the folding of the connecting layer 24. A strength insufficiency of the connecting layer 24 is accordingly reinforced by the film 23.

摘要： PROBLEM TO BE SOLVED: To prevent moisture from being added to an element by a method wherein a case in which the connection part of revolutions sensor is installed is provided, a base body which is connected electrically to the processing circuit of the signal of the element which comprises an InSb magnetoresistance element as a magnet is provided and the element is covered with fluorine oil which cuts off moisture and which passes magnetism. SOLUTION: A pair of magnetoresistance elements 28 are vapor-deposited on the lower part of a base body. An epoxy resin 30 is formed on the rear surface of a tab film 29. Fluorine oil 31 which covers the elements 28, which cuts off moisture and which passes magnetism is formed. As a result, the temperature in the circumference of the revolutions sensor becomes low. Even when moisture is generated as dew formation due to a change in the temperature is added to a part near the elements 28, the fluorine oil 31 acts as a protective layer against the moisture. As a result, the moisture does not come into contact with the pair of magnetoresistance elements 28 composed of InSb, and the InSb in the magnetoresistance elements 28 is not eluted. Thereby it is possible to obtain the revolutions sensor whose output characteristic is not degraded.
