摘要:
An interface cable allows the number of components and manufacturing costs to be reduced. The interface cable has a housing defining an inner volume which has an opening. A first connector is removably connectable to one of a computer and a portable terminal. The first connector protrudes through the opening in the housing. An interface circuit is coupled to the first connector in which the interface circuit is located within the housing. A cable is coupled to the interface circuit. A second connector is removably connectable to the other of the computer and the portable terminal.

A clog indicating device indicating clogging of a dust collecting filter in a dust collector is disclosed. The dust collector includes on an upper region of its casing an exhaust port opening upward, and a cover member is mounted interspatially above the exhaust port. A colored indicating float is so located as to be movable upward between the exhaust port and the cover member due to pressure of an air exhausted from the exhaust port. Clogging of a dust collecting filter is indicated according to a degree of exposure or a position in an up and down direction of the indicating float between the exhaust port and the cover member.

A tool pot according to the present invention includes a synthetic resin portion made from thermo-plastic resin and arranged over an entire length from an opening end to a tool gripping portion. Inner surface of the synthetic resin portion is a tool attachment hole. The synthetic resin portion is provided in the vicinity of the opening end of the attachment hole with a supporting surface for supporting a tool. The synthetic resin portion includes an outer structure defining outer shape, an inner structure defining inner circumference of the tool attachment hole, a cavity provided between the outer structure and the inner structure, and joint ribs joining the outer structure and the inner structure. Each of the outer structure, the inner structure and the joint ribs has wall-thickness enough to secure rigidity of the synthetic resin portion and capable of suppressing mold shrinkage of the synthetic resin portion. The tool pot according to the present invention has rigidity without damaging tools by the synthetic resin portion, and has high dimensional accuracy and design freedom.

A communication adapter includes a cable communication signal processing circuit which enables a PDA to have access to a communication network via a cable and a radio communication signal processing circuit which enables a PDA to have access to a communication network via radio waves. The cable communication signal processing circuit and the radio communication signal processing circuit are provided in a single case or on a single board. The cable communication signal processing circuit and the radio communication signal processing circuit operate simultaneously. By attaching the communication adapter to a PDA, the PDA can have access to the communication network via the cable and to make an access to the communication network via the radio waves. Further, the PDA is capable of communicating with the network via the cable and via the radio waves simultaneously.
