Abstract: A method for growing an epitaxial layer of a group II-VI tenary or quaternary compound on a substrate. In particular a HgCdTe semiconductor layer is grown on a substrate such as sapphire which does not interdiffuse with the materials in the semiconductor layer. Initially a crystalline CdTe semiconductor layer is formed on the substrate and then the substrate with the CdTe layer thereon is placed into an enclosure along with a Hg-Cd-Te source that is rich in Te. The substrate and the source are then heated so as to establish three-phase equilibrium conditions in the enclosure whereby vapors from the source are transported to the CdTe layer and the latter is converted into a ternary semiconductor compound having the composition Hg.sub.1-x Cd.sub.x Te. The substrate with the Hg.sub.1-x Cd.sub.x Te epitaxial layer thereon is useful as a sensing device.

Abstract: This image processing apparatus inputs multi-valued image data, generates first recording data based on the input data, adds together several of the multi-valued image data, generates second recording data based on the added data and selects either the first or the second recording data. The image processing apparatus selects the first recording data in areas corresponding to the several multi-valued image data when preset data are included in those multi-valued image data, and selects the second recording data in areas corresponding to the several multi-valued image data when preset data are not included in those multi-valued image data.

The bias voltage is provided by a superposing a constant current controlled AC voltage and a constant voltage controlled DC voltage. When a DC voltage is applied between the charging member and the member to be charged, the following equation is satisfied..vertline.(applied voltage V)-(charge voltage V.sub.D of the member to be charged).vertline.=.vertline.(charge starting voltage V.sub.TH).vertline..The charge starting voltage is a DC voltage at a level which the member to be charged starts charging when only a DC voltage is applied between the member to be charged and the charging member. When the above relationship is used in the AC voltage application, the charge voltage V.sub.D oscillates in the charge region with a center of DC voltage V.sub.DC.

Abstract: A seat back structure for vehicle seat which includes a separated mat member received into a recessed area in the seat back body which incorporates a male latch member formed by being punched out from a part of a plate frame provided in the seat back so as to project outwardly for latching engagement by a female member attached to a separate mat, and that the female latch member has a width greater than an opening defined in the punched-out part of the plate frame to thereby avoid any direct contact of the male member with the edges of the opening, to thus suppresses the noise between the two latch members. This problem occurs in these types of seats normally as an occupant leans back in the seat and there is a relative movement between the separate mat member and the vehicle seat. The purpose of the invention is to suppress or avoid noise because of relative movement between the two latch members.
