Abstract: In a heat conducting unit, a heat conducting member composed of a material with good heat conductivity shaped in correspondence with the shape of a heat path is contained in a container made of a flexible sheet having a given thickness. The heat conducting member contained in the container connects at least two parts at different temperatures to form the heat path for efficiently transferring heat generated in a higher-temperature part to a lower-temperature part. Heat is dissipated away from the lower-temperature part through the heat path to cool the higher-temperature part.

Abstract: In order to achieve an aspect of the present invention, in a field effect transistor, a compound semiconductor substrate has an active region, and a gate finger electrode is formed on the active region. Source and drain stripe electrodes are formed on the active region to sandwich the gate finger electrode apart from the gate finger electrode. An extended gate electrode is connected with the gate finger electrode and extended source and drain electrodes are connected with the source and drain stripe electrodes, respectively. A resistance section is provided between the gate finger electrode and the extended gate electrode in the transistor forming region.

Abstract: Relating to a stepping motor to be used for paper feedings or type head movements in office automation apparatus such as printers or typewriters.A stator (1) is constituted by moulding stator yokes (2), (3), (4), and (5) monolithically by resin with using their inner radius as their reference, and one side of a rotary shaft (11a) of a rotor (11) is supported by a bearing (12a) of a bearing holder member (1a) which is provided on the one-side end plane of a cylinder member of sad stator (1), and at the same time, a bracket (14) holding a bearing (12b) supporting one side of the rotary shaft (11a) of the rotor (11) is inserted into an opening side inner part of said cylinder member.By the above constitution, centering of the rotary shaft can be carried out easily and the gap between the rotor and the inner radius of the stator can be maintained also easily, then as a result of it, low-cost and high-quality stepping motors can be offered.
