    摘要: In a recessed structure MESFET, an active layer (n-type layer) 2 is provided on a high resistance GaAs substrate 1, a pair of contact layers (n.sup.+ -type layers) 31, 32 is provided on the active layer 2, a source electrode 6 is provided on one contact layer 31, a drain electrode 7 is provided on the other contact layer 32 and a gate electrode 5 is provided on the active layer 2 to achieve a recessed structure. A semiconductor layer 4 having a lower impurity density than that of the contact layer 31, 32 is formed at the recess edge portion at at least drain side to alleviate the concentration of the electric field and current there to suppress the generation of electron-holes pairs by collision ionization to reduce the damage to the crystal lattice by non-luminescence recombination of the electron-holes thus preventing the degradation of the FET characteristics.

    摘要: In a printer for passbooks or the like, a passbook or the like, which is brought in on a transfer path, is stopped at the position of a page-turning roller, where a sheet is turned over by the operation of the page-turning roller. When a sheet is turned over by the page-turning roller, at a position separate from a start position of turning over of a sheet, a passbook or the like undergoes an initial deformation in a out-of-plane direction so that the passbook is bent in a first-order mode. By this initial deformation, a sheet can be turned over steadily. Such a turnover of the sheet can be effected in conjunction with utilizing an optical system which provides an image of the three-dimensional deformation pattern of the passbook which is processed. In accordance with this pattern a decision is made whether or not the out-of-plane deformation of the passbook is more than a specified amount. In the vicinity of the transfer path, a page-turning roller is provided and is supported rotatably. In the vicinity of the transfer path there is also provided a push guide which gives a deformation to the passbook when a sheet is turned over. Based on a frictional control of the page-turning operation, a steady turnover of the sheet can be effected regardless of buckling resistance force of the sheet to be turned over.

    摘要: An air conditioning system for an automotive vehicle includes a duct through which conditioned air is directed into a compartment for passengers. A control device is associated with the duct for operating in a first mode discharging the conditioned air in the form of concentrated currents toward the passengers, in a second mode discharging the conditioned air in the form of diffused currents toward the passengers, and in a third mode in which switching is performed between the first and second modes at variable time intervals. One of the first, second and third modes is selected according to sensed values of compartment temperature and insolation intensity.

    摘要: A drug-releasable medical device contains a controlled drug-release composition comprising 100 parts by weight of an organic polymeric material which is soluble in an organic solvent and insoluble in water, 5 to 60 parts by weight of a lipid-soluble, low molecular weight release auxiliary agent and 1 to 70 parts by weight of a drug. When the composition is applied on a stent, a catheter, an organ replacement medical device, an artificial organ or the like in the form of coating or the like, the medical device is provided with a drug release function. Argatroban or sarpogrelate hydrochloride or both of them are gradually released from the surface of a stent for treating coronary artery stenosis, for example. In order to exhibit a sustained-release function for a desired period of time, the drug to be gradually released is carried in a polymeric material coated on a surface of a metal forming the stent or in a porous stent substrate.
