摘要:
A width of polar teeth is made smaller at a region close to a gate portion 20 than a width of the polar teeth at the other region or a part of the polar teeth is eliminated at the region close to the gate portion 20 and the gap between the polar teeth is thereby increased so as to provide such a cavity as to facilitate the flow of a resin in an axial direction between the polar teeth, whereby the flow of the resin is facilitated.

The present invention addresses the problem of providing a nursing wheelchair, comprising a seat member which deploys on a frame body to form a seat. The nursing wheelchair readily allows transfer of a person receiving care, and is lightweight and easy to operate. A nursing wheelchair (1) comprises seat members (7a, 7b) which deploy on seat support frames (14a, 14b) constituting part of a frame body (2) in order to form a seat.

A battery management system and method accurately estimate a state of charge (SOC) of a battery. For this, the battery management system may include a unit SOC calculator calculating a unit SOC by using a charge/discharge current of a battery, an electromotive force SOC calculator calculating an electromotive force SOC using an electromotive force of the battery; a corrector calculating a compensation amount using the electromotive force SOC and a previous SOC, and an SOC calculator calculating a current SOC using the unit SOC, the previous SOC, and the compensation amount.

A tin-plated product formed by electroplating a substrate in a tin plating solution, which contains carbon particles and an aromatic carbonyl compound, to form a coating of a composite material, which contains the carbon particles in a tin layer, on the substrate has a coefficient of friction which is not greater than 0.18, preferably not greater than 0.13, with respect to the same kind of another tin-plated product, and has a glossiness of not less than 0.29 and a contact resistance of not greater than 1.0 mΩ. The coating has a thickness of 0.5 to 10 micrometers, and the content of carbon in the coating is in the range of from 0.1% by weight to 1.5% by weight. Separate protrusions containing the carbon particles are formed on the surface of the coating. The orientation plane of a tin matrix of the coating is (101) plane.

A printing apparatus which mounts a printing medium on a conveyor belt, conveys it to a printing area, and carries out printing by ejecting a liquid onto the printing medium from nozzles of a liquid ejection head, includes: a tension imparter which imparts tension to the conveyor belt, a tension remover which removes the tension imparted to the conveyor belt by the tension imparter, a conveyance failure detector which detects a printing medium conveyance failure, and a conveyance failure controller which, when the printing medium conveyance failure is detected by the conveyance failure detector, causes the tension remover to remove the tension imparted to the conveyor belt by the tension imparter.

A light source apparatus with modulation function has a wavelength conversion module (75) composed of a nonlinear optical material with a structure having a nonlinear constant modulated periodically. It outputs a difference frequency or sum frequency produced by multiplexing pumping light from semiconductor laser light sources (71) and (72) with different wavelengths through a WDM coupler (74) and by launching the multiplexed light into the optical waveguide. The semiconductor laser light source (72) includes a diffraction grating. The semiconductor laser light source (71) includes a section for modulating output light emitted from its semiconductor laser, and is connected to an external FBG (73) which has a reflection band narrower than a resonance wavelength spacing determined by the device length of the semiconductor laser. The FBG (73) is supplied with the modulated output.

A laser light source is disclosed consisting of first and second lasers that respectively generate laser beams of wavelengths λ1 and λ2. Wavelength λ1 is in the range of 0.9-1.0 μm. A nonlinear optical crystal uses the laser beams of wavelengths λ1 and λ2 as inputs, and outputs a coherent beam having a wavelength λ3 of a difference frequency that satisfies a relationship of 1/λ1−1/λ2=1/λ3. The nonlinear optical crystal has a periodically poled structure of a single period. The wavelength λ3 of the difference frequency varies between 3.1 μm and 2.0 μm when the wavelength λ2 varies between 1.3 μm and 1.8 μm.
