    摘要: A digital telephone set includes a digital telephone circuit and an emergency analog circuit. Normally, the digital telephone circuit is made active so that a handset provided in common therewith is connected to a digital transmission line. In an emergency, the emergency analog circuit is made active instead of the digital telephone circuit so that the handset is connected to an analog transmission line. A dial key pad unit and a speaker are provided in common with the digital telephone circuit and the emergency analog circuit.

    摘要: A vehicle anti-lock braking system having a master cylinder operated upon operation of a brake operating member, a wheel cylinder activated by a pressure produced by the master cylinder, and an anti-lock control device which includes a slip ratio detector for detecting a slip ratio of a drive wheel of the vehicle, and a pressure regulating device for controlling a pressure in the wheel cylinder, so as to maintain the slip ratio in an optimum range. The system also has a traction control device including a traction control power source, and a communication switching device for selective communication of the pressure regulating device with the traction control power source or the master cylinder. The switching device maintains a discharge port of the pressure regulating device in communication with a reservoir while the traction control power source is in communication with the pressure regulating device, and disconnects the discharge port from the reservoir while the master cylinder is in communication with the pressure regulating device.

    摘要: A sheet-like oxygen scavenger for preserving foods or other article in an oxygen-free conditions. This oxygen scavenger is composed of a mixture of fibrous material, iron powder, water and electrolytic material and formed into a sheet-like product by a process which is similar to a paper making process. This sheet-like oxygen scavenger may be covered with gas-permeable film or laminate film. A method of manufacturing the sheet-like oxygen scavenger is also disclosed.
