Title: Production of leathery sheet
Inventor: YONEDA HISAO
IPC: D06N3/00
Filed: 1988-11-30
Abstract: PURPOSE:To obtain the subject flexible sheet excellent in surface strength by napping one surface of a sheet substrate consisting of an ultrafine fiber entangled substance and elastic polymer, temporarily fixing the surface, applying a solvent for the fiber thereto, heat-setting and smoothing the surface and then applying a colorant-containing polymer thereto. CONSTITUTION:One surface of a fibrous substrate consisting of an ultrafine fiber entangled substance capable of forming ultrafine fibers having <=0.5d and an elastic polymer is napped and the above-mentioned napped fibers are paralleled. The surface thereof is then subjected to hot-press treatment and temporarily fixed. A solution consisting essentially of a solvent for the fiber or a swelling agent therefor is subsequently applied and the substrate is then hot pressed to partially join fibers on the surface or form films and smooth the surface thereof. The resultant substrate is subsequently treated in a hot aqueous solution containing or without containing a dye to relax strains. A polymer composition (e.g. polyurethane solution) containing a colorant is then applied to the treated surface of the sheetlike material having the grain side, dried and then subjected to embossing processing to afford a flexible, stiff and smooth leathery sheet, close to natural leather and producing many fine breakages and wrinkles thereon without any blood streaky fiber.

IPC: H04R17/00
Filed: 1987-12-01
Abstract: PURPOSE:To improve the electroacoustic conversion efficiency by coupling a metallic base and a piezoelectric ceramic via a diffusion layer so as to improve the transfer rate of vibration. CONSTITUTION:A piezoelectric ceramic 2 and a nickel plate as a metallic base 3 are overlapped coaxially and they are arranged between a vibration rod 14 and an anvil 15, after the anvil 15 and the vibration rod 14 are pressed, an oscillator 11 is activated to vibrate the vibration rod 14 in the direction of arrow. In this process, the output of the oscillator 11 is adjusted so that the amplitude of the vibration rod 14 reaches nearly 23mum. Through the vibration above, the piezoelectric ceramic 2 and the metallic base 3 are coupled. Then a diffusion layer is formed between the metallic base 3 and a nickel thin film 21 due to a friction heat caused by the ultrasonic wave vibration and the piezoelectric ceramic 2 and the metallic base 3 are bonded strongly by the diffusion layer. Thus, the electroacoustic conversion efficiency is improved.

Abstract: PROBLEM TO BE SOLVED: To reduce noise during travel of vehicles by laying rubber grains onto the surface of a pavement through an adhesive. SOLUTION: A number of rubber grains 12 are laid onto the surface 11 of a drainage asphalt pavement 10 through an adhesive. A high void content is secured on the surface layer 15 of the pavement body 14 formed at the surface of a sub base course 13, and an impermeable layer is formed in the base course 16, in the drainage asphalt pavement 10. Hence, water such as rainwater falling on a road face forming the surface 11 of the pavement body 14 is led to a drain gutter 17 provided at the side of the road face for instance through the voids of the surface layer 15 without penetrating into the sub base course 13 positioned below. The rubber grains 12 are made of synthetic rubber. Irregularities are formed by not only the irregularities of the pavement itself but also those of the rubber grains in the surface 11 of the pavement body 14.  Accordingly, this pavement can be formed with a simple method and noise generated when vehicles travel can be effectively reduced.

Title: Printing controlling method for thermal head
Inventor: KUROSAKI TOMOYUKI
IPC: B41J2/35
Filed: 1986-12-24
Abstract: PURPOSE:To minimize crosstalk noise, by performing an interrupt process with a latch signal and delaying, little by little, strobe signals given to a thermal head, even in one unit. CONSTITUTION:Simultaneously when a latch signal L is supplied from a master slice 9 to a thermal head, the signal is supplied to a CPU 6 as an interrupt signal, thereby starting a timer and sequentially turning ON or OFF, with delays, strobe signals a1-a9 in one unit outputted from a PIO 8, with the period of time generated in an idle step in a firmware as a delay time. Thus, a change in a current passed to a heat generating element of the thermal head can be suppressed to or below the level corresponding to one strobe signal, whereby crosstalk noise is minimized to prevent black prints in the form of refuse from being generated. Accordingly, printing with high quality is achieved.
