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.

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.

A particulate or granular oxygen absorbent comprising at least one ascorbic compound selected from ascorbic acid, ascorbic acid salts or mixtures thereof, an alkali metal carbonate, an iron compound, carbon black and water and the absorbent coated with a finely divided powder are disclosed.
摘要:
A power supply system capable of inhibiting electricity loss and deterioration of each power supply device while realizing high stability in the case where electricity supply is performed by using a plurality of power supply devices is provided. A switching element corresponding to a power supply device having a higher inter-terminal voltage out of two power supply devices selectively becomes in ON state, and a switching element corresponding to a power supply device having a lower inter-terminal voltage selectively becomes in OFF state. Thereby, overload on a specific power supply device is prevented, and current flow between the different power supply devices is able to be prevented without generating needless electricity loss. Further, since electricity of the power supply device having a higher inter-terminal voltage is selectively outputted, variation between the respective power supply devices becomes allowable to some extent.

A fuel cell system that is able to perform power generation more stably than in the past regardless of external environment is provided. Based on a temperature of a power generation section detected by a temperature detection section, a supply amount of a liquid fuel from a fuel pump is adjusted, and therefore control in which the temperature of the power generation section becomes constant is performed. In addition, a fuel cell system that is able to perform power generation in a vaporization supply type fuel cell more stably than in the past is provided. A level of a power generation voltage supplied from the power generation section is raised by a boost circuit. In a control section, operation of the boost circuit is controlled using a given control table, and therefore control is performed on an output voltage and an output current supplied from the boost circuit to a load.
