Abstract: A surface mount optical semiconductor device and circuit can efficiently transfer and dissipate heat even when being mounted together with electronic circuit components. The optical semiconductor device can include a lead frame having a concave portion for mounting a light-emitting element therein and a pair of electrode terminals connected to a board. A sealing resin portion can be provided for sealing a surrounding region of the concave portion. A bottom surface of the concave portion is located at a predetermined distance from a connecting surface on which the pair of electrode terminals is connected to the board. The bottom surface of the concave portion can also be exposed from a bottom surface of the sealing resin portion. Thus, the bottom surface of the concave portion and the device in general can be air-cooled efficiently.

Abstract: To provide a telephone communication system in which the occurrence of the situation of talking on the phone by using a hands-free device (i.e., while doing something such as driving a car) is prevented or reduced in talking by using a cellular phone. The present invention makes a caller voluntarily cancel the calling or cut short the talking by sending and saving a connection state between a hands-free device 110 and a cellular phone 11 to an exchange 15; if a phone call is made to the cellular phone 11, checking the connection state of the hands-free device 110 to the cellular phone 11; and if the cellular phone 11 is using the hands-free device 110, informing that before establishing a connection between the caller side and the cellular phone 11.

Abstract: The present invention aims at providing a recording method for making a request for selecting whether or not to perform finalizing processing on a disc inserted in a DVD-R or a DVD-RW recording device, capable of reducing unnecessary operations and effectively using the recording capacity of the DVD-R or the DVD-RW. The DVD-R or the DVD-RW recording device includes user information input/output means including recording means for recording data in the disc and display means and central processing means for processing information input by the user or recorded information in the inserted disc, inputs and sets a reference based on which a finalizing processing selection is displayed, detects the presence/absence of a finalizing record of the inserted disc and an amount of remaining capacity therein, decides and displays whether the detected amounts meet the reference or not, performs finalizing processing as required and performs processing of unloading the disc.

Abstract: A robot is disclosed in which load torque imposed on motors is reduced and therefore small-sized motors can be used. In the robot, an arm member, a first link, a second link and a third link constitute a parallel linkage, and the first link and the third link are coaxially pivotally supported on a base. With a pivotal shaft for pivotally connecting the second link and the third link, one end of a fourth link having shorter link length than the link length of the third link is pivotally connected to the second and third links and one end of a fifth link having the same link length as that of the fourth link is pivotally connected to the other end of the fourth link. The other end of the fifth link is pivotally supported on the base with a pivotal shaft to which the rotary shaft of the motor is coupled, so that the fifth link can move according to the rotation of the motor.
