A field effect transistor including a gate insulation portion, an organic semiconductor portion, a source electrode and a drain electrode, wherein when a voltage is applied to the gate at 70° C. for 5.0±0.1 hours so that the field strength in the gate insulation portion would be 100±5 MV/m, the change in the threshold voltage is within 5 V. The organic semiconductor portion has a high driving stability, of which the change in characteristics by driving is thereby small.

In a connector member comprising an insulator body with a plurality of contacts, a casing has an inside surface defining an opening as a counterpart member receiving space for receiving a counterpart member. To provide water-tight seal between the opening and the connector member, the casing is formed with four connector portions. The opening has a surrounding sealing inside surface lined with a sealing member, with the counterpart member surrounded by a counterpart sealing ring which matches the sealing member.

A reflector has a base body which is made of a metallic material having an ionization potential substantially higher than that of aluminum. An aluminum reflecting layer is formed on one surface of the base body by vacuum deposition. Furthermore, a light-transmitting water-insoluble inorganic oxide layer is formed on the aluminum reflecting layer. The light-transmitting inorganic oxide layer has its micropores sealed by H.sub.2 O or a carboxylate of an iron family element having a low valence. An insulating layer is formed to cover at least the other surface and the peripheral side of the base body.

A connector assembly has a first connector, a second connector matable with the first connector along a mating direction, a mating assistance mechanism, a mating maintenance mechanism, and a detection mechanism. The mating assistance mechanism has an operation member and is operable to mate the second connector with the first connector in accordance with an operation of the operation member. The mating maintenance mechanism includes a stopper, an engagement portion and an elastic support. The engagement portion is configured to be engaged with the stopper in a mating state of the first connector and the second connector so as to maintain the mating state. The elastic support is configured to support the engagement portion. The elastic support is elastically deformed and moves the engagement portion along a direction different from the mating direction when the second connector is mated with the first connector. The detection mechanism is operable to detect the mating state and includes a first terminal, a second terminal, and a short-circuit member, The first terminal has a first contacting section extending along the mating direction. The second terminal has a second contacting section extending along the mating direction. The short-circuit member is arranged to establish a short circuit between the first terminal and the second terminal in the mating state. The short-circuit member has a first contact and a second contact which are brought into contact with the first contacting section and the second contacting section in the mating state, respectively. The first contact is directly/indirectly moved by movement and elastic deformation of the elastic support so that the first contact wipes the first contacting section during a mating operation of the first connector and the second connector. The second contact wipes the second contacting section independently of the elastic deformation of the elastic support during the mating operation.
摘要:
An object of the present invention is to manufacture a material for concrete by using a fresh concrete sludge as a starting material. The invention relates to a method of manufacturing a material for concrete in which a material for concrete is manufactured from a slurry composed of a fresh concrete sludge obtained by treating a fresh concrete waste to separate a coarse aggregate and a fine aggregate. The manufacturing method comprises a grinding step of obtaining a product containing fine particles with a mean particle size of 10 μm or less by wet grinding the slurry under a condition of water content of 60 wt. % or more.
