Provided are a method and an apparatus that enable rapid and automatic determination of the coagulant injection rate in a process of water treatment through coagulation and sedimentation. Using a coagulation analyzer comprising sample tanks 1A to 1D each for keeping a predetermined amount of raw water, a water supply pump 7, water supply/discharge valves 4, 6 for raw water and washing water, mixers 3A to 3D, a coagulant injection unit 21, and a detector 30 for determining the particle size and the particle number of flocs, the time within which the coagulant 20 injected into the sample tanks is dispersed by mixing and the particles begin to agglomerate (agglomeration start time) is determined, and based on the thus-determined agglomeration start time, the coagulant injection rate is determined, or the amount of the coagulant to be injected is controlled.

[Object]The present invention relates to a turmeric pigment composition. More specifically, the present invention provides a turmeric pigment composition in which aggregation and sedimentation of a turmeric pigment over time is effectively prevented even when a concentrated amount of turmeric pigment is incorporated in a solvent; the turmeric pigment composition also ensures a desirable color-developing property, and is capable of stably adding a deep color with a bright tone, which was never accomplished by a hitherto-known colorant.

A light source unit mounted in a mount portion of a vehicle includes a heat block and a reflector accommodated in an imaginary cylinder that is defined by a holding device for holding an outer circumference of a lens. A first heat dissipating portion and a second heat dissipating portion, which are partitioned by a partition plate, are provided on an outer circumferential surface of the heat block. A plurality of fins are projected on the first heat dissipating portion which is disposed on a lens side of the heat block so as to extend in a circumferential direction, and a second plurality of fins are projected on the second heat dissipating portion so as to extend in an axial direction of the heat block. The partition plate includes a mounting rib, and a mounting device is provided on the mounting rib for mounting the light source unit in the mount portion of the vehicle.

The lens shift measuring apparatus calculates a position of a predetermined portion of a frame body, on the basis of an imaging result obtained by imaging reflected light from the frame body, in a state in which light is irradiated onto a lens-attached member having a lens and the frame body to hold the lens, such that the reflected light from the frame body is generated, and calculates a position of a focusing spot, on the basis of an imaging result obtained by imaging light transmitted through the lens, in a state in which the light is irradiated onto the lens-attached member, such that the focusing spot formed by focusing the light transmitted through the lens by the lens is generated, and calculates a shift amount of the position of the focusing spot with respect to the predetermined portion as the shift of the lens.

In an imaging apparatus, an erroneous shake correction is prevented from being performed due to a front curtain shock. A shutter selecting section determines a current state is a shake-correction execution mode when a shake correction switch is ON, when a tripod detection sensor tripod is not mounted, when a shake detection sensor senses a shake amount equal to or larger than a predetermined value, and when a shutter speed is lower than a predetermined value. In this case, the shutter selecting section selects an electronic focal plane shutter as the front curtain, and supplies an operation command signal to an electronic focal plane shutter control section. In other cases, the shutter selecting section determines the current state is not the shake-correction execution mode, and selects a mechanical focal plane shutter as the front curtain and supplies an operation command signal to a shutter drive control section.

A vehicle lighting system having: a light guiding member having a front face as a light emitting surface, a rear face having a plurality of reflecting portions inclined to the front face, and a side face; and a light source disposed opposite to the side face. An angle θ defined between the front face and the side face is designed such that, of external lights to enter into the light guiding member, a light to travel directly to the side face can be totally reflected on an interface of the side face.
