摘要:
A small reactor with high heat-release performance is provided. A reactor 1 includes an assembly (10) and a case (4), the assembly (10) having a coil (2) and a magnetic core (3) at which the coil (2) is arranged, the case (4) housing the assembly (10). The case (4) includes a bottom plate (40) that contacts a fixing object when the reactor (1) is installed on the fixing object, a side wall (41) that is mounted on the bottom plate (40) with an adhesive and surrounds the assembly (10), and a junction layer (42) that fixes the coil (2) to an inner surface of the bottom plate (40). The bottom plate (40) is formed of a material with higher thermal conductivity than that of the side wall (41). The reactor (1) easily transfers heat of the coil (2) to the bottom plate (40) and hence has high heat-release performance because the reactor (1) includes the bottom plate (40) with the high thermal conductivity and the coil (2) is joined to the bottom plate (40) through the junction layer (42). Since the bottom plate (40) and the side wall (41) are integrated using the adhesive, the thicknesses of both the members (40, 41) can be decreased. Accordingly, the reactor (1) is small.

Provided is a reactor including a coil, and a core having an inner core portion arranged inside the coil and an outer core portion covering the outside of the coil. The inner core portion of the reactor has a higher saturation magnetic flux density than that of the outer core portion. The outer core portion has a lower permeability than that of the inner core portion, and is made of a mixture of a magnetic material and a resin. The case has a heat-transfer portion at an inner wall surface, as a heat-radiation structure for at least one of the coil and the inner core portion. With the reactor, even if the outside of the coil is covered with a core member, heat generated in the reactor can be effectively dissipated.

A motorcycle design that easily secures space for exchanging tires. A unit-swing type, rear wheel driving power unit is disposed on one side of a rear wheel in a transverse direction and has a swing fulcrum in front of a rear wheel axle, and a right and left pair of rear suspension units are disposed on right and left sides of the rear wheel. An installation height of the rear suspension unit on an opposite power unit side is higher than an installation height of the rear suspension unit on a power unit side, and an installation position of the rear suspension unit on the opposite power unit side in a width direction of the vehicle body relative to the rear wheel is more inside than an installation position of the rear suspension unit on the power unit side in the width direction of the vehicle body relative to the rear wheel.
摘要:
A chemical analyzer for measuring a concentration of components of a sample liquid, by mixing the sample liquid with reagents, so as to react the reagents upon the components thereof, includes a carrier having an introducing portion through which the sample liquid is injected, passages for distributing the sample liquid injected from the introducing portion, and plural reactor portions which hold the sample liquid therein to be mixed with the reagent, thereby to react. A movable driver portion is provided on which the carrier is mounted and a reagent charging device is provided for ejecting the reagents which are different for the respective plural reactor portions of the carrier, sequentially. Further, a detector is provided for detecting the components after mixing the reagents with the sample liquid.
摘要:
Microcapsule-reagents are prepared by previously reacting at least a part of an antigen or antibody attached to microcapsules encapsulating a labeling substance with an antibody or antigen which is specifically reactive therewith, and then the reagent thus prepared is reacted with a sample containing an antigen or antibody in the presence of a complement, whereby highly sensitive immunoassay of the antigen or antibody in the sample can be realized even when the antigen or antibody attached to the microcapsules has a lowered activity or has only low reactivity with the antibody or antigen in the sample.
摘要:
A method for immunoassay for an antigen involves the following steps: reacting a sample possibly containing an antigen to be determined, a definite amount of a conjugate of the antigen and a charged substance and a definite amount of labeled antibody specific for antigen; allowing the reaction products to electrophoretically migrate towards a carrier bearing an attached antibody specific for the charged substance, so that when the reaction products contact the carrier any reaction product of labeled antibody and antigen passes through the carrier and any reaction product of the labeled antibody and conjugate binds to the carrier attached antibody specific for the charged substance; determining the amount of labeled antibody thereby bound to the carrier and relating the determined amount of labeled antibody to the amount of antigen in the sample.
摘要:
A digital display device for forming one or more electro-transmissive display patterns, which comprises a pair of oppositely disposed electrodes to which a signal is supplied for energization. Each of the electrodes includes a number of electro-conductive sections which are disposed with a lower distribution density at the central portion and with a higher distribution density at the contour portion. This mode of distribution of the sections gives an equivalent visual contrast to the situations in which all the sections are disposed with a uniform distribution while at the same time reducing the power consumption rate.

An electronic timepiece, used as a pager watch, has a speaker for emitting an alarm sound at a preset time and also for reproducing an external call signal intercepted by a receiver for incoming electromagnetic waves. The receiver may be maintained normally inactive, being periodically activated for short time intervals under the control of a frequency divider in the output of a crystal oscillator serving to drive an electro-optical display. Sensors responsive to abnormal ambient conditions, e.g. temperature or blood pressure of the wearer, may also operate the speaker.
