Abstract: A laminated body is provided in a circumferential shape with a gap formed in a part of a circumferential direction on a semiconductor layer. In the laminated body, a first insulating layer, a gate layer, a second insulating layer, and a drain layer are layered in this order from the semiconductor layer side. An impurity diffusion layer is formed on a surface of the semiconductor layer, and a backside electrode on a backside surface. The impurity diffusion layer extends from a position in contact with side walls in a channel space to an outside of the laminated body through a region corresponding to the gap on the surface of the semiconductor layer. A portion of the impurity diffusion layer beyond the laminated body is a contact region to which a wiring for applying a predetermined voltage is connected. A cover layer made of an insulating material is formed in an upper portion and a periphery of the annular portion including the laminated body and the gap.

Abstract: A vacuum channel field effect transistor includes a first insulator on a p-type semiconductor substrate, a gate electrode on the first insulator, a second insulator on the gate electrode, a drain electrode on the second insulator, and an n+ impurity diffusion layer in the surface of the p-type semiconductor substrate, the n+ impurity diffusion layer being in contact with a side wall including side faces of the first insulator, the gate electrode, and the second insulator. Application of predetermined voltages to the n+ impurity diffusion layer, the gate electrode, and the drain electrode causes charge carriers in the n+ impurity diffusion layer to travel through a vacuum or air faced by the side wall to the drain electrode, which can increase the source-drain current.

Abstract: The invention provides a control device for mutually monitoring two microcomputers at a low cost while reducing a parts number and doubly monitoring abnormality in each of the microcomputers. The control device transmits a reset signal to a main microcomputer and resets the main microcomputer when a frequency of a first pulse signal deviates from a normal frequency range determined by a frequency calculating means, in which the first pulse signal is output from the main microcomputer, and the frequency calculating means calculates a frequency of the first pulse signal by an input of the first pulse signal to a sub microcomputer. The control device transmits a reset signal to the sub microcomputer and resets the sub microcomputer when a frequency of a second pulse signal deflects from a normal frequency range, by an input of the second pulse signal to the main microcomputer from the sub microcomputer.

Abstract: A (semi)grain-finished leather-like sheet composed of an entangled nonwoven fabric of three-dimensionally entangled fiber bundles containing microfine long fibers and an elastic polymer contained in the entangled nonwoven fabric. When dividing the (semi)grain-finished leather-like sheet to five layers with equal thickness, i.e., surface layer, substrate layer 1, substrate layer 2, substrate layer 3 and back layer in this order along the thickness direction, part of the microfine long fibers forming the surface layer and/or the back layer are fuse-bonded to each other and the microfine long fibers forming the intermediate layer are not fuse-bonded. With such a fuse-bonding state of the microfine long fibers, the (semi)grain-finished leather-like sheet combines a low compression resistance and a dense feel each comparable to natural leathers, has a sufficient practical strength, and are excellent in properties which are required according to its use.

Abstract: A method of producing a substrate suitable for artificial leathers. The substrate is composed of an entangled nonwoven fabric made of microfine fibers and a binder resin. At least one surface of the substrate is a densified layer which is made of the microfine fibers and which is substantially free from the binder resin. The binder resin is impregnated into a portion of the substrate other than the densified layer. The densified layer prevents the binder resin impregnated into the entangled nonwoven fabric from migrating into the surface of the entangled nonwoven fabric, thereby providing the substrate having the surface substantially free from the binder resin. The peeling strength between the substrate and a grain layer formed on the surface thereof is drastically improved because the surface of the substrate is substantially free from the binder resin.
