摘要:
A cooling water control valve apparatus capable of independently controlling flow rates of cooling water in two lines with a single apparatus for cooling water control and capable of achieving cost reduction.A cooling water control valve apparatus which adjusts a flow rate of cooling water for cooling an object to be cooled includes two inlet ports through which cooling water is introduced, an electrical control valve which is arranged at a first passage communicated with one of the inlet ports and which adjusts a flow rate of cooling water flowing through the first passage with electronic control, and a thermosensitive valve which is arranged at a second passage communicated with the other of inlet ports and which adjusts a flow rate of cooing water flowing through the second passage owing to displacement of a temperature detecting medium with temperature.
摘要:
A labeled polynucleotide is subjected to hybridization with oligonucleotide probes fixed respectively to regions on a supporting material. With a first restriction enzyme, a single-stranded moiety of the labeled polynucleotide having failed to form a double strand with each probe is separated from a double strand having been formed by the labeled polynucleotide and each probe. First detection data is obtained from each region. A mismatching moiety, at which the labeled polynucleotide and a certain probe have undergone a mismatch binding, is separated with a second restriction enzyme, and second detection data is obtained from each region. The region to which the mismatch polynucleotide was bound is specified in accordance with results of a comparison between the first detection data and the second detection data.

摘要:
The present invention provides an ester compound represented by a formula I: ##STR1## wherein R.sub.1 denotes a hydrogen atom or a methyl group; R.sub.2 represents a 1-methyl-2-propenyl group, a 1-methyl-2-propynyl group, a 3,3-dihalogeno-1-methyl-2-propenyl group, or a C.sub.1 -C.sub.1 6 alkyl group which may be substituted with at least one halogen atom; and R.sub.3 represents an acid residue of pyrethroids.The invention also relates to an active agent for controlling noxious insect pests containing the ester compound as an active ingredient, an intermediate for production of the ester compound and a process for producing the intermediate. The ester compound represented by the formula I has good activities for controlling noxious insect pests.
摘要:
A fuel supply system for a boat, which prevents fuel piping from becoming complicated, includes a vapor separator unit connected to a fuel tank that is mounted on a hull and holds fuel supplied to an engine section, a low-pressure pump arranged to discharge the fuel reserved in the fuel tank into the vapor separator unit, and a mounting hole for a valve, a fuel passage section, and a pipe section (relief path) that return the fuel discharged by the low-pressure pump to the suction opening section side of the low-pressure pump when a tank section is filled with a predetermined amount of fuel. The mounting hole for the valve, the fuel passage section, and the pipe section (relief path) are integral with the vapor separator unit.
摘要:
A skin barrier function recovery and promotion composition containing, as an active ingredient, a fragrance which is effective when evaluated by applying a predetermined stress to a model experimental animal, in a system to which the tested fragrance is not applied, to thereby reduce the skin barrier function of the animal and using this data of the degree of recovery of the skin barrier function as an indicator and evaluating the capability by the difference between this data and data of the degree of recovery of the skin barrier function in a system to which the tested fragrance is applied.
摘要:
There are disclosed novel ether compounds of the general formula: ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are each hydrogen or the like; A is a group of the general formula: ##STR2## B is a group of the general formula: ##STR3## and X is oxygen or sulfur; and harmful-organism controlling agents containing them as active ingredients.
摘要:
An electromagnet device for an electromagnetic contactor is formed of a frame with an opening, a movable-contact supporter slidably disposed in the frame, a movable contact supported by the movable-contact supporter, a movable core connected to the movable-contact supporter, and a stationary core for attracting the movable core. The stationary core includes a base plate for closing the opening of the frame, at least one columnar arm core fixed to the base plate to extend therefrom, and at least one pole piece fixed to the arm core at a side opposite to the base plate. The pole piece provides attracting force to the movable core when the stationary core is energized. In the electromagnetic device, a device for partly interrupting a magnetic path of the stationary core is formed. The interrupting device reduces remanent flux in the stationary core when the stationary core is deenergized.

摘要:
Disclosed are skin immune function controlling agents which contain as the active ingredient a volatile substance capable of stimulating the olfactory receptor, as typified by a specific perfume. By controlling the skin immune function, these agents serve, for example, to enhance the skin barrier function and to prevent or treat skin contact hypersensitivity.
