Disclosed are a projection display apparatus and a projection optics provided in the projection display apparatus. The projection optics has a refractive optics and a reflective optics. In the refractive optics, a lens (non-circular lens) provided on a reflective optics side has a non-circular shape forming part of an imaginary circular region whose center is an optical axis center of the refractive optics. In other words, the non-circular lens has a shape of a cut-out portion of an imaginary circular lens having an optical axis center coinciding with the optical axis center of the refractive optics.

A peel-apart type instant photographic apparatus using a negative film and a positive sheet. The apparatus has a dark box for developing and accommodating the negative film and positive sheet, or supply, joined together and having a developer spread therebetween. The dark box is removable from the apparatus body and, therefore, easy to clean and handle. When the dark box is not mounted on the apparatus body in predetermined conditions, a printing operation is inhibited to eliminate the waste of negative sheets and positive sheets. A printing operation is also inhibited when the supply is left in the dark box.

An image recording apparatus has a feed system for feeding a recording sheet from a feed magazine to a drum, a drum system for winding the recording sheet therearound and rotating to align the recording position with a predetermined position on the circumferential surface of the drum, a scanning system for main-scanning the recording sheet at the recording position of the sheet with an optically modulated beam, and a storage system for storing the recording sheet on which an image has been formed. The drum is rotated in opposite directions during feed and storage of the sheet.

A method of forming a second semiconductor layer on a first semiconductor layer by vapor growth is disclosed. The two semiconductor layers are of the same conduction type but have different impurity concentrations. In the forming process, a doping gas is supplied before the vapor growth of the second semiconductor layer is started whereby a steep impurity distribution is established in the vapor-growth boundary.

A bubbling evaporator comprises: a vessel (11); a partition plate (11a) for dividing the vessel (11) into an upper chamber (11b) for temporarily storing carrier gas and a lower chamber (11c) for containing liquid (2); an inlet pipe (12 or 14) for making the carrier gas blow from the upper chamber (11b) into the liquid (2) in the lower chamber (11c) through the partition plate (11a) to bubble and evaporate the liquid (2); and an outlet pipe (13) for leading the evaporated vapor together with the carrier gas to the exterior of the vessel (11). Thus, backflow of the liquid (2) to the exterior of the vessel (11) can be prevented and stable pressure of the evaporated vapor can be obtained. A method of evaporating a liquid organic metal to be used in a vapor deposition process for manufacturing semiconductor devices and the like is also disclosed.
摘要:
A method of fabricating a semiconductor laser device includes disposing a lower cladding layer, a superlattice active layer, an upper cladding layer, and a contact layer in the named order on a substrate, forming resonator end surfaces, disposing, on the resonator end surfaces, films containing a material that disorders the semiconductor superlattice structure when diffused into the superlattice structure, and passing a current between the substrate and the contact layer to cause laser oscillations. The laser oscillations produce laser light that is absorbed at the resonator end surfaces. The resonator end surfaces are locally heated due to absorption of laser light whereby the disorder-causing material is diffused from the films into the resonator end surfaces and the semiconductor superlattice structure in the vicinity of the resonator end surfaces is thereby disordered to form window regions.
摘要:
An apparatus for adjusting the inclination of an optical element or the like is provided with a predetermined shaft, an optical element fitted to the predetermined shaft, a mounting seat for supporting the optical element, a keep member for holding and fixing the optical element between it and the mounting seat, and a spherical seat movable in a direction intersecting the predetermined shaft between the mounting seat and the optical element for adjusting the inclination of the optical element. A method for mounting and adjustng the optical element includes the steps of mounting the optical element on the spherical seat supported on the predetermined shaft, detecting an inclination angle of the optical element and shifting the spherical seat to adjust the optical element.
