Abstract: A gas concentration measurement device measures a gas concentration based on an absorbance of sample gas in a region between a light source that emits infrared light and a detector that detects the infrared light. The gas concentration measurement device includes a rotating member, first and second band pass filters on the rotating member, and a rotational driver. The first and second band pass filters are located on a pair of planes that intersect each other. The rotational driver rotates the rotating member around the rotating shaft to switch between a first state, in which the infrared light from the light source is transmitted through the first band pass filter, and a second state, in which the infrared light from the light source is transmitted through the second band pass filter.

Abstract: A power supply module includes a circuit board and a heatsink plate. The circuit board includes a first principal surface, a second principal surface, and side surfaces. Electronic components are mounted on the first principal surface. The heatsink plate includes a plate-shaped body portion that faces the first principal surface, and a plurality of fixing portions that extend at an angle from the body portion to face the side surfaces. The fixing portions are configured to come into contact with the second principal surface to secure the body portion to the circuit board.

Abstract: A card-type device that includes an antenna body disposed on a housing and movable along a turning shaft between an upright position and a flat position. An antenna turning member applies an urging force to the antenna body in a direction in which the antenna body turns to the upright position. A locking projection projecting and a corresponding locking portion which is fitted to the locking projection when the antenna body is in the flat position, stops the antenna body from turning. When the antenna body moves in a direction in which the antenna body is to be unlocked, the locking projection is released from the locking portion, and the antenna body automatically turns toward the upright position by the urging force of the antenna turning member.

Abstract: A shield case shields an electric circuit on a circuit board by covering a front surface and a side peripheral surface of the circuit board. The shield case includes a frame section vertically arranged on a mother board and covering the side peripheral surface of the circuit board, and a lid section including a plate member provided at an upper end of the frame section and covering the front surface of the circuit board. The circuit board is arranged in the frame section at a position spaced apart from a front surface of the mother board, and has a circuit-side connector at a back surface of the circuit board. The circuit-side connector is connected with a mother-board-side connector provided at the mother board, so that an electric circuit of the circuit board is electrically connected with a conductive portion of the mother board.

Abstract: An antenna body disposed on a housing through a turning shaft in a state in which the antenna body is movable along the turning shaft within an allowable movement range. The antenna body turns on the turning shaft within a range between an upright position to stand on an upper surface of the housing and a flat position to be laid flat. An antenna turning elastic member is provided so as to apply an urging force to the antenna body in a direction in which the antenna body turns to the upright position. One of the antenna body and the housing has a locking projection projecting toward the other, and the other of the antenna structure body and the housing has a locking portion which is fitted to the locking projection when the antenna body is laid flat and which stops the antenna body from turning.

Abstract: A compact flash (CF) card includes, in a front portion, a space-entering portion that enters the space between a top plate and a bottom plate provided on the upper and lower sides of connecting terminal pins arranged at the front end of a CF-card storage section of a PC card adapter. The connecting terminal pins are protected by the top plate and the bottom plate. The CF card storage section of the PC card adapter has an opening in the upper surface on the card insertion side. An upper portion of the CF card that is exposed from the opening includes a tall portion having a greater height than the space-entering portion. The CF card can be loaded in a PC card adapter having a simple structure, and taller electronic components can be mounted in the tall portion, than in a CF card which is equal in height to the space-entering portion over the entire range from the front end to the rear end.

Abstract: A connector device includes lock male screws which can be screwed to lock female screws of an apparatus on which a locking operation is carried out, nuts for freely inserting the lock male screws and for allowing movement of the lock male screws between a screwed position and a non-screwed position, and lock female screws which, with the lock male screws being retracted to the non-screwed positions, are screwed to the nuts, and which are screwed to lock male screws of the apparatus on which a locking operation is carried out. By switching the states of the lock female screws between a mounting state and a non-mounting state with respect to the nuts, the lock screws of the connector device can be used even if the forms of the lock screws change with respect to the connector device. This causes the female connector and the male connector to be firmly secured together, thereby making the connector device more versatile.
