A compact and highly efficient hybrid magnetic refrigerator includes a hybrid refrigerating apparatus wherein an evaporator of a vapor compression refrigeration cycle and a heat exchanger of a magnetic refrigeration cycle are thermally connected. The magnetic refrigeration cycle is provided with a magnetic refrigeration unit in which a magnetic substance dissipates and absorbs heat according to the increase and decrease of a magnetic field in order to heat and cool a refrigerant circulating in its vicinity. The heated refrigerant is cooled by the evaporator of the vapor compression refrigeration cycle and the cooled refrigerant is supplied to the heat exchanger cooling the outside air.

Although sintered wire with lower resistance was preferable as a scan line and a signal line in conventional art in order to make a voltage drop small, there was a problem in electric connection with an electrode which constructs a cathode. In the present invention, a cathode which has an electron-emitting region 16 on a substrate 10 is constructed of a base electrode 11, a top electrode 13, and a protective insulating film 14 sandwiched by these electrodes, the base electrode 11 becomes a signal line, and sintered wire 18, used as a scan line, and the top electrode 13 are connected with an sub-electrode 17. The sub-electrode 17 includes metal included in the sintered wire 18, and metal included in the top electrode 13.

A tip of a wire formed in the shape of a ball is bonded to an electrode by using a tool. A part of the wire is drawn from the tip bonded to the electrode. A bump is formed on the electrode by deforming a portion of the wire continuous with the tip on the tip by using the tool. The wire is cut while leaving the bump on the electrode.

A spring contact 10 has a pair of round contact projections 11 and 12 symmetrically formed at both sides of a peak of a bending top thereof. The spring contact is fixed to an insulator 20 at a central portion thereof and has a second contact region 13 at a lower end thereof. The spring contact is located in a natural condition where no external force is applied. In this condition, the round contact projection 11 is located at a position remotest from the surface of the insulator. When an electronic part approaches perpendicularly to the surface of the insulator, a contact pad of the electronic part at first touches one of the round contact projections 11 and finally touches the other of the round contact projections 12 after the spring contact is deformed and displaced to a deformed position. At this time, the wiping displacement d of the spring contact in the direction perpendicular to the connecting direction of this connector is extremely small.
摘要:
A corrosion degree measuring method capable of field measurement for intergranular corrosion, particularly the sensitization degree, of the plant's structural materials in a narrow space. The metal electrode made of a material being measured and the counter electrode to the metal electrode are immersed in an electrolytic solution. A voltage is applied to the metal electrode in the anodic direction so as to raise the potential of the metal electrode up to the passive state potential and to keep the metal electrode at the passive state potential. The passive state potential is used as a reference potential, and a pulse-like potential signal is applied to the metal electrode in the cathodic direction. At the time of the application of the pulse potential signal, a current between the metal electrode and the counter electrode is measured, and the corrosion degree of the material being measured is determined from the intensity of the current.

In an electrical connection member having elasticity and adapted to be interposed between connection objects for electrically connecting them together, an inner member has a plurality of spring pieces each extending from a base plate portion, an outer member including a flexible insulating film and a plurality of conductive paths formed at the flexible insulating film. Each conductive path has a first and a second contact portion for connection to the connection objects. Each spring piece includes a root portion formed adjacent to the base plate portion and faced to a portion, corresponding to the second contact portion, of an inner surface of an intermediate portion of the insulating film. Each spring piece further includes an inclined spring portion extending obliquely from the root portion and faced to a portion, corresponding to the first contact portion, of the inner surface of the intermediate portion.
