A power generatorincludes: a fuel electrodethat receives a supply of fuel gas; an air electrodethat receives a supply of air; an electrolyte layerdisposed in between the fuel electrodeand the air electrode; a gas flow channelthat circulates therein the fuel gas or the air, with the fuel electrodeor the air electrodebeing exposed to at least part of the gas flow channel; a porous bodyfilled in the gas flow channel; and a porous sheetpresent in contact with the porous bodyand the fuel electrodeor the air electrode, the porous sheetbeing made of a material having electrical conductivity, the material having pores formed to spread in a uniform manner, the pores being larger in diameter than pores formed in the porous body

Power generator

A rotary tool is provided with a mode selecting part that selects one operating mode from a predetermined plurality of operating modes when a mode switching button is pressed. The plurality of operating modes include: a first auto stop mode where a motor rotates only for a first time period after an impacting operation is detected; and a second auto stop mode where the motor rotates only for a second time period which is shorter than the first time period after the impacting operation is detected.

Rotary tool

An electricity generation device includes: a tubular fuel cell having an electrolyte layer sandwiched between inside and outside electrodes to which a fuel gas is supplied, the fuel cell having an interior formed as an inside channel for the fuel gas; a cover pipe arranged around the fuel cell with a gap provided between the outside electrode and the cover pipe; a connecting member connecting the fuel cell and the cover pipe to each other and permitting an outside channel for the fuel gas to be formed around the fuel cell by making use of the gap; and a fuel gas pipe connected to each of opposite ends of the cover pipe and forming a flow path for the fuel gas in cooperation with the cover pipe.

Electricity-generation device

An electricity generation device () using a fuel cell () having a fuel electrode () and an air electrode () to which a fuel gas and air are supplied, respectively, includes: a fuel gas conduit () through which the fuel gas flows; a cover () configured to cover an outside of the fuel gas conduit () and cooperating with a peripheral wall () of the fuel gas conduit () to form an air passage () therebetween, the air passage extending along the fuel gas conduit (); an air inlet hole () formed through the cover () to allow air to flow into the air passage (); and an air outlet hole () provided downstream of the air electrode exposed to the air passage (), to cause the fuel gas conduit () and the air passage () to communicate with each other.

Roaming mobile communication system and method

Mobile communications system and communications network

A switching center 30 comprises a memory part M2, a memory part M3, and a memory part M4. The memory part M2 stores a terminating terminal number corresponding to and registered by each subscriber. The memory part M3 stores idle/busy information corresponding to each terminal. The memory part M4 stores idle/busy information corresponding to each subscriber. When a subscriber 11.sub.1 makes a call at a terminal 12.sub.2, the switching center 30 determines whether the idle/busy information for the subscriber 11.sub.1 stored in the memory part M4 is idle or busy. When the idle/memory information represents idle, the switching center 30 refers to the idle/busy information for the terminal 12.sub.2 stored in the memory part M3. When this idle/busy information represents idle, the switching center 30 reads out the terminal number of a terminating terminal of a terminating subscriber stored in the terminating terminal memory part M2 and performs an outgoing call connection process. At this point, the switching center 30 also sets the idle/busy information for the subscriber 11.sub.1 and the terminal 12.sub.2 to busy state. When the subscriber 11.sub.1 makes a call, while the terminating terminal 12.sub.1 is performing an incoming call connection process for the subscriber 11.sub.1, since the idle/busy information for the subscriber 11.sub.1 has been set to the busy state, even if the terminal 12.sub.2 is idle, the switching center 30 does not perform an outgoing call connection process for the subscriber 11.sub.1 at the terminal 12.sub.2.

A manual printer has a casing of a shape suitable for mounting on a table, a guide rail installed in the casing, a guide member movably connected to the guide rail, a base supported on the cursor and projecting outwardly through a front opening of the casing, a printing head attached to the base, a controller contained in the casing, a switch panel installed in the casing, a display secured to the casing so as to display printing data, and an ink ribbon cassette arranged in the base. In a printing operation, an operator inputs the printing data to the memory of the controller and the base is moved by hand along the guide rail in order to have the printing head print words and the like onto paper sheets.
