IPC: B29C51/12
Filed: 1988-02-29
Abstract: PURPOSE: To easily bond a single material piece to a rigid substrate so as to strictly reproduce the contour of a fabric by bonding a porous spongy lining fabric to a thermoplastic substrate and applying a non-flat contour to the substrate and the fabric by vacuum molding. CONSTITUTION: The fabric piece 50 having an elastic sponge state (e.g. an elastic polyurethane foam 52) already bonded to the rear of a fabric is loosely arranged on an upwardly turned female mold 30 so that a fabric surface is turned downward. Next, an extrusionmoldable thermoplastic substrate 60 is heated until it becomes 'bendable' or flowable to be arranged on the fabric piece 50 equipped with a spongy liner within the upwarly turned female mold 30. After this arrangement, a vacuum is immediately applied to the substrate 60 through vacuum holes 44. Vacuum force is sufficiently strong to suck the fabric piece 50 and the substrate 60 into the female mold 30 so that the fabric piece 50 and the substrate 60 obtain the shape or contour of the female mold to suck a flowing thermoplastic material into the fibers of the fabric.  After a vacuum is applied, a produced article is taken out after the used specific thermoplastic material is sufficiently cooled.

Title: Image forming device
Inventor: KIZU SHINICHI
IPC: G03G21/00
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To improve printing accuracy by preventing the step-out of a photoreceptor roller driving part at the time of driving-start and driving-end by disposing a transmission changeover means performing the transmission and nontransmission of driving force between the photoreceptor roller and the photoreceptor roller driving part driving the photoreceptor roller. SOLUTION: When a photoreceptor 4 is turned, the driving force of the photoreceptor roller driving part 1 is transmitted to the photoreceptor roller 5a connected to a transmitting part 3 by connecting the photoreceptor roller driving part 1 with a changeover gear 2 and the changeover gear 2 with the transmitting part 3. When the photoreceptor 4 is not turned, the driving force of the photoreceptor roller driving part 1 is prevented from being transmitted to the photoreceptor roller 5a connected to the transmitting part 3 by separating the changeover gear 2 from the transmitting part 3. Thus, the photoreceptor roller driving part 1 and the photoreceptor roller 5a are connected and disconnected through the changeover gear 2, so that the photoreceptor roller 5a is driven or not driven by the photoreceptor roller driving part 1.

CONSTITUTION:A synchronization protective counter table and a frame pattern generation table FT, etc., are written in a memory means 4. At every time of an output from a multiplexing part 3, and an input of position information from the FT and a frame bit, the means 4 compares coincidence/noncoincidence of the multiplexing output and the frame bit by the synchronization protective counter table, and when they coincide continuously (n) times, an asynchronous state and a write address are updated to a synchronizing state and a stepped address, respectively, and when they do not coincide (m) times, the synchronous state is updated to an unstepped specific write address. In a buffer 5, a synchronization protective count value, a write address, etc., from the means 4 are stored, and thereafter, sent out to the means 4 again. A frame converting part 6 writes a multiplexing output to the part corresponding to the write address from the means 4. In such a way, the change of the circuit constitution and the circuit design can be decreased.

Title: Manufacture of epitaxial wafer for light-emitting diode
Inventor: ISHIDA MIKITOSHI
IPC: H01L21/205
Filed: 1986-03-06
Abstract: PURPOSE:To obtain a light-emitting diode, whose luminance is hardly deteriorated even by lighting for a prolonged time, by previously executing annealing under conditions, in which the vapor pressure and temperature of arsenic or an arsenic compound are specified, and using a wafer, on which a single crystal substrate, residual thermal stress of which is relaxed, is grown in an epitaxial manner. CONSTITUTION:When a single crystal layer consisting of a III-V compound is grown on a gallium arsenide single crystal substrate in an epitaxial manner and an epitaxial wafer for a light-emitting diode is shaped, a gallium arsenide single crystal substrate annealed under the conditions of the vapor pressure of 2-760mmHg of arsenic or an arsenic compound and a temperature of 700-1,100 deg.C is used. Arsenic remarkably escapes from the surface of gallium arsenide when vapor pressure is less than 2mmHg at that time, and the pressure resistance of an annealing device must be increased when vapor pressure exceeds 760mmHg. Annealing does not progress sufficiently when the temperature is less than 700 deg.C, and quartz instruments employed for annealing are deformed and impurities from quartz are mixed when it exceeds 1,100 deg.C.
