Abstract: In a webbing take-up device, a moving member is moved while being guided along a cylinder in order to rotate a spool in a take-up direction. A urging plate of a guide member urges a flange at an axial direction leading end portion of the cylinder toward a restricting direction side, and a leg plate of a frame restricts rotation of the flange toward the restricting direction side. This enables rattling of the axial direction leading end portion of the cylinder about the axial direction of the cylinder to be suppressed.

Abstract: A manufacturing method for a secondary battery and a manufacturing apparatus for a secondary battery that are applicable to a secondary battery in which an electrolyte solution injection hole has a diameter of 1.5 mm or more are provided. The secondary battery includes a battery case including a cover plate provided with an electrolyte solution injection hole, and a sealing member sealing the electrolyte solution injection hole. The manufacturing method includes a preparing step and a press-fitting step. The preparing step is preparing a cell in which, after an electrolyte solution is injected to the battery case through the electrolyte solution injection hole, the sealing member is disposed on the electrolyte solution injection hole. The press-fitting step is press-fitting the sealing member into the electrolyte solution injection hole while applying press-fitting load and ultrasonic vibration with a frequency of 20 kHz or more in parallel to a press-fitting direction.

Abstract: A webbing take-up device is provided with a spool that takes up a webbing, a lock base, and a cover plate that covers an outer periphery of the lock base. A tooth portion is formed at the outer periphery of the lock base. The lock base rotates the spool when a rack contacts the tooth portion. The webbing take-up device is further provided with a guide provided at the cover plate. The guide supports the lock base to be rotatable. Thus, contacting together of the ratchet teeth and the lock base is restricted.

Abstract: A lithium ion battery (11) that is a test object is housed in a vacuum chamber (14). An initial exhaust pipe (47) and an inspection exhaust pipe (51) are connected to the upper portion of the vacuum chamber (14). The inside of the vacuum chamber (14) is subjected to an initial exhaust through the initial exhaust pipe (47) to lower the pressure inside the vacuum chamber (14) to an inspection pressure (Pe). Thereafter, an inspection exhaust is performed through the inspection exhaust pipe (51). A sensor unit (16) is interposed in the inspection exhaust pipe (51). Exhaust gas passing through the inspection exhaust pipe (51) flows into the sensor unit (16) from an inlet port, and is caused to flow perpendicularly toward the sensor face of a gas sensor by a nozzle provided inside the sensor unit (16). The exhaust gas passes through the inside of the gas sensor, and is discharged to outside of the sensor unit (16) from an exhaust port.

The polygon scanner scans a light beam modulated by the one-dimensional spatial light modulating element in a direction that is substantially perpendicular to the length direction of the one-dimensional spatial light modulating element so as to display an image.

Abstract: A photocatalytic water-processing system decomposes organic and inorganic materials present in water. The system includes a reservoir for storing the water to be processed, a main unit formed separately and connected to the reservoir, an inlet pipe for guiding the water from the reservoir to the main unit, an outlet pipe for returning the water to the reservoir, and a pump for guiding the water from the reservoir to the main unit and returning the water. The reservoir has an electrode unit therein for electrolyzing the water so as to flocculate and precipitate the inorganic materials in the reservoir, and a filter is arranged within the main unit. Also, a photocatalytic processing device is arranged within the main unit at a downstream side of the filter for decomposing the organic material in the absence of scale formed of the inorganic materials.

Abstract: Speckle noise is reduced to increase image quality in an image display apparatus such as a projection display or the like. An illuminating optical device in an image display apparatus (1) applies a laser beam L to a GLV (spatial modulator) (6) and modulates the laser beam based on an image signal input to the GLV to display an image. A plurality of laser beams (1, 1, . . . ) each having an optical path difference greater than the coherence length of the laser beam are applied to the GLV.
