Title: Decorative sheet and manufacture thereof
Inventor: MUNEDA KOICHI
IPC: B32B3/30
Filed: 1990-05-18
Abstract: PURPOSE:To obtain the touch, appearance and hue very similar to those of natural leather showing variable density having depth by providing an opaque colored or colorless synthetic resin layer on a base material and further providing a perspective colored synthetic resin layer having recessed and protruding parts different in size thereon. CONSTITUTION:An opaque colored or colorless synthetic resin layer is laminated to a perspective synthetic resin layer and a base material is bonded thereto and release paper is subsequently peeled off. As the synthetic resin constituting the opaque colored or colorless synthetic resin layer, there is a synthetic resin such as a vinyl chloride resin or a rubbery synthetic resin other than said synthetic resin. In the case of the colored synthetic resin, pigment or a dye is compound with the synthetic resin. The perspective colored synthetic resin layer has recessed and protruding parts different in size and the sizes of the recessed and protruding parts are variously different. When the perspective colored synthetic resin layer constituted of the recessed and protruding parts is too thick, perspective properties are easy to lose and, when too thin, the formation of the recessed and protruding parts becomes impossible and the average thickness of the layer is pref. set to 10/20mum.

IPC: F16D13/64
Filed: 1980-09-16
Abstract: PURPOSE: To prepare the titled disc having high density and low porosity, without using a metallic core plate, by forming the teeth engaging with a spline integrally with the ring-shaped main body from the sheet prepared by bonding natural pulp fibers with a thermosetting resin.  
     CONSTITUTION: Natural pulp fibers (e.g. wood) are used as a main material, and if necessary, mixed with synthetic organic fibers (e.g. phenolic resin fibers, etc.) and/or inorganic fibers (e.g. asbestos). The fibers are mixed with 4W100wt% of a water-soluble thermosetting synthetic resin (e.g. melamine resin) as a binder, and a large amount of water. A sheet is prepared from the mixed liquid, and is formed to a preformed body 110, which is hot-pressed with molds 12, 13 having cavities corresponding to the plane shape of the objective frictional engaging disc. The teeth to  be engaged with the spline are formed to the inner or the outer circumference of the ring-shaped main body by this molding process,to obtain the objective disc.

Title: Manufacture of semiconductor device
Inventor: IZAWA NOBUYUKI
IPC: H01L21/3205
Filed: 1987-05-27
Abstract: PURPOSE:To prevent effectively electromigration and the like, by applying almost uniform strain to a wiring, and making the crystal grain size of the wiring material large by heat treatment. CONSTITUTION:After the forming of necessary constitution elements, a wiring film 12 formed on a semiconductor substrate 11 is pressed by a roller 13. Then, strain remains all over the inside of the wiring film. The pressing pressure of the roller 13 is made almost constant, in order to apply almost uniform strain to the wiring film 12. After that, patterning is performed, and heat treatment for recrystallization is performed. On the contrary, the necessary patterning can be performed, after recrystallization by heat treatment. The crystal grain size of the wiring film is made large by the above heat treatment, and crystal having uniform grain size can be obtained from the uniform strain. Thereby, a wiring with excellent film quality can be formed, and electromigration is effectively prevented.

Abstract: PURPOSE:To allow the vertical double size display of a low duty ratio by adopting the circuit constitution to generate two pulse of the shift lock signal of a common driver outputted in the beginning of one horizontal scanning in the time shorter than the time of the one horizontal scanning period. CONSTITUTION:The clock signal YSCL is outputted by the successive time shifting to output signals Q1 to Q4 from a shift register 1 to 4 according to a clock signal CK. The inversion outputs of the output Q1 and the output Q2 are ANDed by a gate 6 and the inversion outputs of the output Q3 and the output Q4 are ANDed by gate 5 and are further, ORed by a gate 7, by which the clock signal YSCL 2 as the two pulses of the short time is obtd. This clock signal YSCL 2 is used as the clock signal of the shift clock of the common driver. The controller is, therefore, put into the selection state at the pulse width of one horizontal scanning period nearly simultaneously during the period when the data of the one horizontal scanning period is outputted from the segment drivers. The vertical double size display of the low duty ratio is pos sible in this way.
