摘要:
An optical module where breaking of an optical fiber is avoided to improve ease of handling in the assembly process of the module and mechanical reliability of the module including resistance to impact. The optical module has a PD (3) and an optical fiber (5a) that are mounted on the same substrate (2). A covering section (6) for covering the optical fiber (5a) is placed on a deep trench section (24) having a predetermined depth in the Z2 direction from a V-groove-formed surface where a V-groove for mounting the optical fiber (5a) is formed. The distance h from an end face (3a) of the PD (3) to an end face (24a) of the deep trench section (24) and the distance k from an end face (51a) of the optical fiber (5a) to an end face (6a) of the covering section (6) satisfy the relationship of h>k. The optical fiber (5a) is mounted with both the end face (6a) of the covering section (6) and the end face (24a) of the deep trench section (24) made to be in contact with each other.

摘要:
The present invention is intended to provide a fuel consumption evaluation system which obtains quantitative data to determine whether actual driving has consumed fuel more efficiently or less efficiently than average driving and gives the driver and/or manager concrete advice for fuel-efficient driving based on the obtained data, and also provide a fuel consumption evaluation system which decides, based on obtained fuel efficiency data, whether driving is more fuel-efficient than average driving and sets a target and gives the driver and/or manager concrete advice for fuel-efficient driving based on the obtained data in consideration of change in vehicle total mass without any influence of slopes and traffic flows and particularly encourages and instructs, in real time, the driver to do fuel-efficient driving. The system comprises: engine speed measuring means (2) which measures engine speed of a truck (1); accelerator opening degree measuring means (3) which measures an accelerator opening degree (α); vehicle velocity measuring means (4) which measures vehicle velocity (V); fuel flow rate measuring means (5) which measures a fuel flow rate (Fw); and control means (10) which evaluates fuel consumption of the truck from measured engine speed (N), accelerator opening degree (α), vehicle velocity (V) and fuel flow rate (Fw).

A stencil clamping portion which clamps a tip end of a stencil sheet on an outer peripheral wall of a drum is provided, and the stencil sheet clamped by the stencil clamping portion is wound and attached around the outer peripheral wall. The stencil clamping portion includes an insertion slit which is provided along an axial direction of the drum and open to a surface of the outer peripheral wall, and an elastic sheet which pinches the stencil sheet inserted into the insertion slit. The tip end of the stencil sheet is inserted into the insertion slit by an insertion blade, and pinched by the elastic sheet.

The present invention intends to provide a non-human animal model of Guillain-Barré syndrome, which can be obtained by immunizing FcγRIIB-gene-deficient non-human animal with ganglioside GQ1b, and a screening method of a therapeutic agent for Guillain-Barré syndrome using the non-human animal model. A mouse model of Guillain-Barré syndrome is generated by immunizing FcγRIIB-gene-deficient mice with gangliosides GM1, GM2, GD1a, and GQ1b together with Freund's adjuvant every three weeks four times in total.

The imaging lens system of the present invention comprises, in order form an object side to an imaging surface side: a first lens having a positive power with its convex surface facing the object side; a second lens in a meniscus shape having a positive power with its concave surface facing the object side; and a third lens functioning as a correction lens, wherein the imaging lens system satisfies following expressions: 0.25
摘要:
In a powder coating apparatus a pulse signal S2 of a low voltage generated by a pulse signal generation circuit (7) is boosted to a high voltage by means of a high voltage impression circuit (8), so that it is impressed upon corona electrodes (5). As a result, a corona discharge is intermittently generated from the corona electrodes (5) toward an object to be coated, whereby powder coating material sprayed from a nozzle opening of a gun main body in a forward direction is charged with negative ions developed by the corona discharge, whereafter it is directed toward the object to be coated, and is deposited on a surface of the object.

A method for producing rare earth sintered magnets includes the steps of pressing and compacting an alloy powder for the rare earth sintered magnets, thereby preparing a plurality of green compacts, arranging the green compacts on a receiving plane in a direction in which a projection area of each of the green compacts onto the receiving plane is not maximized, and heating the green compacts, thereby sintering the green compacts and obtaining a plurality of sintered bodies.
摘要:
A method and apparatus for manufacturing a rare earth magnet is disclosed. In a first step, a compact is produced by compacting rare earth alloy powder in a predetermined space in an orienting magnetic field. Next, a demagnetizing process is performed for the compact, and the compact is ejected from the predetermined space. Then, a additional demagnetizing process is performed for magnetic powder adhering to a surface of the compact by applying an magnetic field to the compact after the compact is ejected.

A stencil printing machine, which includes: a drum which is freely rotatable and has an outer peripheral wall formed of an ink impermeable member, in which a stencil sheet is mounted on a surface of the outer peripheral wall; an ink supplying device for supplying, to the surface of the outer peripheral wall, an ink guided from an ink tank; an ink recovery device for recovering, from an ink recovery portion, an extra ink on the surface of the outer peripheral wall; and a pressure roller which presses a print medium to the outer peripheral wall. The ink tank includes a main tank portion where unused ink is stored, and a sub-tank portion where the ink recovered by the ink recovery device is stored. The ink supplying device preferentially supplies the ink in the sub-tank portion.
