A driving motor comprises a rotor having a rotatably supported shaft, a rotor case rotating together with the shaft, a hub seat attached to the rotor case for mounting a disk hub and a chucking magnet for magnetically attracting the disk hub and a thrust ball bearing having a washer, a plurality s of balls and a retainer for holding the balls and supporting the load in the thrust direction of the rotor. The motor also includes a flatness control section which passes through the rotor case to contact the washer of the thrust ball bearing and controls the flatness of the washer and a position control section which passes through the rotor case to contact an inner circle surface of the washer of the thrust ball bearing and controls the washer in the thrust direction. The chucking magnet, flatness control section and position control section are integrally molded of resin.

A lighting device preventing an illumination variation on a surface to be irradiated. The lighting device has a first light emitting surface section (102a) which is a surface formed by rotating a bus with a central axis as a rotation axis in a first angle area (−θ1≦θ≦θ1) of an angle (θ) relative to a cross section of the bus which is an intersection line with the cross section perpendicular to a surface (801a) to be irradiated and including the central axis of a lighting lens (100), a second light emitting surface section (102b) formed in a second angle area (θ1≦θ≦180° and −180°≦θ≦−θ1) of the angle (θ) so that a light flux emitted toward the surface (801a) increases as compared with the case where the first light emitting surface section (102a) is formed in a whole-angle area (0°≦θ

A fluid handling apparatus 10 has a plurality of fluid handling subassemblies 16 arrayed on a plate body 12. Each of the fluid handling subassemblies includes: an injecting section 26 for injecting a fluid; a fluidized section 28 for allowing the fluid to continuously flow downwards; a fluid housing chamber 30 for receiving the fluid from the fluidized section; a wall portion 20 formed between the fluid housing chamber and the fluidized section; slits 20b for allowing the fluid to enter the fluid housing chamber; and a surface-area increasing means 22 for increasing the area of a contact surface with the fluid in the fluidized section. The slits extend from a lower end positioned in the vicinity of the lower end of the fluidized section, to an upper end higher than the upper end of the fluidized section, for allowing the injecting section and fluidized section to be communicated with the fluid housing chamber.

Provided are a lighting lens and an illumination apparatus including the same that can improve color rendering properties and prevent reductions in performance of a light flux controlling member and in illuminance on a surface to be illuminated when a pseudo-white LED is used. This lighting lens (1) includes a color adjustment unit (14) that contains a color adjusting material, is excited by light emitted from an LED (2) and emits light in a color different from the light-emitting color of the LED (2). The color adjustment unit (14) is disposed at a portion through which sub-rays other than main rays pass and not at a portion through which the main rays pass, the main rays being rays having a luminous intensity equal to or more than a predetermined percentage of the maximum luminous intensity.

摘要:
It is to make a separate component for preventing disengagement of a strip plate incorporated into a frame unnecessary, to allow attachment and detachment of the strip plate to and from the frame by a single operation, and to allow the strip plate and the frame to be smoothly attached and detached without the strip plate disengaging from the frame during a manual operation such as transportation and without specimens and the like within wells spilling when an external force is applied to attach and detach the strip plate to and from the frame.In a fluid handling device 1, an eaves section 27 of a first side wall 5 is engaged with a recess 37 of a strip plate 3 including a plurality of wells using concavity and convexity. An eaves section 28 of a second side wall 6 is engaged with a recess 38 of the strip plate 3 using concavity and convexity. Slits are formed in a corner section of the second side wall 6 connecting to another side wall, so as to extend downwards from an upper end section 6c. The second side wall 6 is partially cut away from the other side wall and is more easily deformed than the first side wall 5.
摘要:
A light-emitting device combining a first luminous flux control member having a total reflection surface and emitting light from an emission surface in a narrow angle range centered mainly on an optical axis, and a second luminous flux control member arranged to surround the total reflection surface of the first luminous flux control member. The second luminous flux control member (102) of the light-emitting device is provided with a second incidence surface (126a) and a second emitting surface (126b). Of the light emitted from the light-emitting element (200), the light incident to the second incidence surface (126a) is within a range of angles θ larger than a largest angle to the optical axis of the light incident to the first luminous flux control member (101). The second emitting surface (126b) controls the light incident to the second incidence surface (126a) to have light distribution characteristics different from those of the light emitted from the first luminous flux control member (101), and emits the light.
