Abstract:
Provided is a process for producing bleached pulp, including subjecting unbleached pulp, which is obtained by cooking a lignocellulose substance, to alkali-oxygen bleaching treatment and then subjecting the alkali-oxygen bleached pulp to chlorine-free bleaching treatment including chlorine dioxide treatment, wherein in at least one chlorine dioxide treatment stage in which the chlorine dioxide treatment is performed, monopersulfuric acid is used in combination. The amount of chlorine dioxide to be used is reduced and the color reversion resistance of the bleached pulp is improved by this process.

A submount that enables the reliable mounting of a semiconductor light-emitting device on it, and a semiconductor unit incorporating the submount. A submount 3 comprises (a) a substrate 4; and (b) a solder layer 8 formed on the top surface 4f of the substrate 4. The solder layer 8 before melting has a surface roughness, Ra, of at most 0.18 μm. It is more desirable that the solder layer 8 before melting have a surface roughness, Ra, of at most 0.15 μm, yet more desirably at most 0.10 μm. A semiconductor unit 1 comprises the submount 3 and a laser diode 2 mounted on the solder layer 8 of the submount 3.

A magnetic tape (1) characterized by having a backcoating layer (5) which comprises a binder and fine particles having been dispersed in the binder and being capable of irreversibly changing in color on oxidation reaction, and has a sufficient number of microvoids of sufficient size to supply sufficient oxygen to cause the oxidation reaction.
Abstract:
An accelerated fuel passage of an accelerator pump operatively connected with a throttle shaft having a throttle valve. The accelerated fuel passage is connected to an upstream side of a needle orifice, which orifice is coupled to a main nozzle. Consequently, the fuel is discharged by the accelerator pump into an area before the needle orifice. By the addition of a one-way check valve system in a fuel pick up at a metering chamber for a fuel circuit, the fuel driven by the accelerator pump piston is discharged to a venturi tube of an intake passage through the main nozzle. A self pumping effect caused by an engine pulsation is dampened or eliminated by the needle orifice. Further, a check valve is provided within a fuel pick up at a metering chamber for a fuel circuit, whereby the fuel driven by the accelerator pump piston is discharged to a venturi tube through a main nozzle without returning to the fixed fuel chamber.

Abstract:
A method of writing servo signals on a magnetic tape which comprises irradiating one end of an optical fiber bundle (12) comprising a plurality of optical fibers (11) arrayed in parallel with each other with laser light, transmitting the laser light (24) emitted from the other end as an output light source through a condensing lens (13), and irradiating a site of a magnetic tape running at a prescribed speed, the site being capable of forming servo tracks, with the laser light passed through the condensing lens (13) to form real images (25) equal to or smaller in size than the output light source to cause the site to change physically or chemically thereby forming a plurality of servo track patterns (S) in the longitudinal direction of the tape at a smaller pitch than the pitch of the optical fibers (11) arrayed in the optical fiber bundle (12).
Abstract:
A number of link plates molded of synthetic resin are pivotally connected together by connecting pins to form a molded conveyor particularly suitable for the conveyance of delicate or easy-to-break articles. Each link plate has a plurality of aligned bush holes formed at intervals along a trailing end edge of the link plate, and a plurality of aligned pin holes formed at intervals along a leading end edge of the link plate. Each of the connecting pins is inserted alternately into the pin holes in one link plate and the bush holes in the adjacent link plate to pivotally connect these two link plates. A locking projection formed on the connecting pin to lock the connecting pin in position against detachment is located closer to one end of said connecting pin than to a longitudinal central portion of said connecting pin. The locking projection thus arranged reduces a stroke of hammering required to drive the connecting pin into the pin and bush holes. The connecting pin further has a flange-like stopper serving to position the locking projection within one of the bush holes when the connecting pin is in its fully inserted position.
