摘要:
A data terminal equipment which is coupled to an ISDN through an access line and uses a hierarchical protocol in conformity to an OSI reference standard model includes the following structural elements. A first data link protocol circuit provides a link access procedure balanced (LAPB) modulo-8 data link protocol. A second data link protocol circuit provides an LAPB modulo-128 data link protocol. A third data link protocol circuit provides a data link protocol based on a link access procedure for a data channel (LAPD). A protocol determining circuit determines a data link protocol to be used by referring to an address field and a control field of a cell set-up signal which is supplied from a second data terminal equipment. A data link protocol activating circuit selects and activates one of the first, second and third circuits on the basis of the result provided by the protocol determining circuit.

An insulating varnish comprising water-soluble polyesters and which can be used as an enamel or protective coating for electric wires is disclosed. The insulating varnish is prepared by reacting an aromatic dicarboxylic acid component and a polyhydric alcohol component to produce a high molecular weight polyester resin, addition reacting a polybasic acid with the resulting polyester resin to obtain a carboxyl group-containing polyester resin and dissolving the resulting polyester resin in water using a basic compound.

A semiconductor device is manufactured by covering a semiconductor substrate of a predetermined conductivity type with a polycrystal layer of a semiconductor material. Selected portions of the polycrystal layer are oxidized into an insulating material during heat treatment. Remaining portions of the polycrystal layer which are left unoxidized act as conductive portions. On manufacturing a bipolar transistor, ion implantation is carried out in a predetermined solid angle to introduce an impurity of an opposite conductivity selectively in a preselected one of the remaining portions. During the heat treatment, the impurity diffuses into the substrate only from the preselected portion to form a PN junction in the substrate. For fabricating an MOS transistor, an oxide film is preliminarily formed on the substrate selectively on an area on which a predetermined one of the remaining polycrystal layer portions is to be formed. Ion implantation is carried out to introduce an impurity of the opposite conductivity in the respective remaining layer portions. The oxide film prevents the impurity from diffusing to the substrate. The impurity diffuses into the substrate only from the respective remaining portions, except the predetermined portion.

A communication device may receive first information from a terminal device in a case where a first communication link is established via a first type of interface between the communication device and the terminal device. The communication device may determine whether a communication via a second type of interface between the communication device and the terminal device is performable, establish a second communication link via the first type of interface between the communication device and the terminal device, and perform a two-way communication of second information with the terminal device by using the second communication link in a case where it is determined that the communication via the second type of interface is performable. The communication device may not perform the two-way communication of the second information with the terminal device in a case where it is determined that the communication is not performable.

A manufacturing method for a toothed member includes a thickened tooth shaping process in which a toothed shape is formed on a side wall portion while making a thickness of the side wall portion larger than a thickness of a bottom surface portion by relatively moving the compression die with respect to the restraint die and the pressure receiving member in the axial direction from the side of the opening end of the cup-shaped raw material toward the bottom surface portion. The manufacturing method being such that the thickened tooth shaping process includes applying a load against the restraint die such that the restraint die restrains the first surface and the second surface.

A manufacturing method for a toothed part including a bottom surface portion and a side wall portion provided to extend upright from an outer peripheral end portion of the bottom surface portion, the side wall portion being formed with teeth. The manufacturing method includes a half drawing process of performing draw shaping on a material having a disk shape to form the bottom surface portion and the side wall portion, an inside diameter of which becomes larger in a direction away from the bottom surface portion; and a tooth shaping process of forming the teeth in the side wall portion.

The wireless communication device may determine in which of a parent state and a child state the wireless communication device is to operate in a case where the wireless communication device receives a first type of signal, and determine the wireless communication device is to operate in the parent state in a case where the wireless communication device receives a second type of signal. The wireless communication device may send a first wireless profile to a first external device so as to establish a wireless connection with the first external device in a case where the wireless communication device is to operate in the parent state, and receive a second wireless profile from a second external device so as to establish a wireless connection with the second external device in a case where the wireless communication device is to operate in the child state.
