Abstract: A sensor device has a display part that displays a numerical value and a character on a casing and at least three switches. The switches have an up switch and a down switch. The up switch has a function of changing the numerical value to increase and also the down switch has a function of changing the numerical value to decrease. Each switch has a different function and each switch has a different symbol.

Abstract: A switch includes a switch main body having a movable section displaceable downward by pressure to bring a movable contact into contact with a fixed contact, the movable section being displaced upward to open each contact by a release of pressure; a button section that presses the movable section in response to a downward pressing operation; and a support arm having one end portion supporting the button section. An end of the support arm not coupled to the button section is turnable and held at a location in a support surface arranged vertically. The button section bottom surface is inclined and separated from the movable section when the button section is not pressed. When the button section is pressed and is lowered to a position at which the fixed contact and the movable contact are closed, the bottom surface is in an approximately horizontal state and presses the movable section.

Abstract: An indicator drive circuit includes a current mirror circuit including a first transistor located at a control side and a second transistor located at a controlled side, a current through the current mirror circuit being switched by an external control signal, a current source adapted to feed a control current to the first transistor of the current mirror circuit, and a switching element adapted to be driven by a current through the second transistor of the current mirror circuit and to switch on or off an indicator light source. The current source includes two transistors cascode-connected.

Abstract: A lock device locks a lid of a glove box and the like, and prevents half-latching of locking. When a lid starts closing, a left lock rod is driven to a right side, and a left lock arm turns counterclockwise against a spring force of a lock arm spring so as to start fitting into a catch hole of a catch on a left side. When the left lock rod is further driven to the right side, the left lock rod is completely fitted into the catch hole in a state wherein a lock claw of the left lock arm comes to a horizontal state. When the left lock rod is driven to the right side up to a final position, the left lock arm slightly moves to the right side. However, even in this state, the catch and the left lock arm maintain a sufficient engagement state.

Abstract: Disclosed is a fuel cell including a fuel cell stack; a stack case which contains the fuel cell stack; and a blocking device including connecting portions which electrically connect, to output terminal portions of the fuel cell stack, output cables to transmit the output of the fuel cell stack to a device provided outside the stack case, the blocking device being capable of blocking the mutual connection performed by the mechanical operation of the connecting portions from the outside of the stack case. Moreover, at least a portion of the blocking device in which the output cables are electrically connected to the connecting portions is arranged outside the stack case.

Abstract: A load drive device has a load drive unit including an input system electrically connectable to a control power supply and an output system electrically connectable to a load drive power supply. The load drive unit supplies the electrical load with load drive voltage from the load drive power supply via the output system when the control power supply applies control voltage to the input system. A potential difference detection unit detects a potential difference between the control voltage and the load drive voltage. A potential fixing unit fixes a potential at a control system electrical route, connecting the control power supply and the input system of the load drive unit, to a prohibition level that prohibits the output system of the load drive unit from driving the electrical load when the potential difference detected by the potential difference detection unit exceeds a predetermined threshold value.

Abstract: A load driving device including a semiconductor switch arranged in a current path extending from a power supply to a load. A control circuit controls activation and deactivation of the semiconductor switch. The control circuit deactivates the semiconductor switch when it is determined that overcurrent is flowing through the current path. A current detector detects current that is flowing through the current path. The control circuit determines that overcurrent is flowing when the current detector continuously detects current that is greater than a threshold value over a predetermined detection time. The detection time is set to be shorter than the time from when the current in the current path exceeds the threshold value to when an increase in resistance value of the semiconductor switch resulting from heat generated by the current lowers the current to the threshold value.

Abstract: Relays and the like are arranged so that any restriction is not imposed on a portion where a fastening member between end plates or the like is disposed. To realize this, a relay assembly is provided in a stack case. In this case, when the relay assembly is integrated with a service plug, cables between relays and the service plug can preferably be omitted. Moreover, the relay assembly includes a resin plate to which the relays and the service plug are attached, and these relays are electrically connected to the service plug via buses on the resin plate.

Abstract: An output cable for transferring an output of a fuel cell stack to a device provided outside a stack case and an output terminal portion of the fuel cell stack are connected to each other, and a blocking device capable of blocking the fuel cell stack from supplying the output thereof to the device through mechanical operation from outside the stack case is provided. In the stack case, a first through hole for allowing for maintenance and checkout from the outside of the stack case to the inside is formed, and the blocking device is attached so as to cover this first through hole from outside. The blocking device includes a housing made of a solid body, a second through hole for communicating the outside of the stack case with the inside by communicating with the first through hole, and a closing cover for closing the second through hole.

Abstract: A program for use with an information processing apparatus offers a price of an appliance to be disposed of is. The program is operable to effect the step of providing an accepting price at which the appliance is to be accepted for disposal. The accepting price is determined in accordance with appliance data of the appliance and disposal way data representing a way of disposing of the appliance. The program is operable to further effect the step of sending a message of a request for accepting and taking away from the consumer the appliance for disposal to an information processing apparatus of a business concern related in the disposal way, which is determined based on the data of the designated disposal way.
