An eight-way valve including a housing and a rotary member is provided. The housing includes an annular wall, a first chamber, a second chamber, a third chamber, and a fourth chamber. The annular wall is provided with 16 upper-tier openings and 16 lower-tier openings. The rotary member includes an upper-tier switching part configured to switch between opening and closing of each of the 16 upper-tier openings, and a lower-tier switching part configured to switch between opening and closing of each of the 16 lower-tier openings. The upper-tier switching part includes an upper-tier first communication passage, an upper-tier second communication passage, and an upper-tier closing part, and the lower-tier switching part includes a lower-tier first communication passage, a lower-tier second communication passage, and a lower-tier closing part. Any one of a first space to an eighth space is respectively provided with a port.

A power transmission device includes: a case including a first oil reservoir configured to store oil, a second oil reservoir configured to store the oil, and a partition wall configured to separate the first oil reservoir and the second oil reservoir from each other; the oil enclosed in the case; a rotating member configured to contact the oil in the first oil reservoir; and an opening and closing member located in the partition wall and configured to supply the oil from the second oil reservoir to the first oil reservoir. The oil level in the first oil reservoir when the opening and closing member is open is higher than the oil level in the first oil reservoir when the opening and closing member is closed, and is high enough for at least a part of the rotating member to be dipped in the oil.

A power transmission device includes: a case including a first oil reservoir configured to be able to store oil, a second oil reservoir configured to be able to store the oil, and a partition wall configured to separate the first oil reservoir and the second oil reservoir; the oil sealed in the case; a rotating member configured to be able to be in contact with the oil in the first oil reservoir; and an oil supplying unit configured to be able to supply the oil in the second oil reservoir to the first oil reservoir. The oil supplying unit is configured to be able to adjust an amount of the oil in the second oil reservoir supplied to the first oil reservoir.

A chirality detector of the present invention for detecting chirality of chiral material, includes: a first electrode and a second electrode that are configured to apply a voltage to a subject containing the chiral material; a spin detection layer configured to be in contact with the subject; a power supply; and a control section. The power supply and the control section are configured to generate an electric field at the subject by applying the voltage between the first electrode and the second electrode. The control section is configured to detect a voltage generated in the spin detection layer in a direction that goes across a direction of the electric field or a voltage generated between the spin detection layer and the subject, and also is configured to detect chirality of the chiral material on the basis of the detected voltage.

Disclosed is an intake air volume measuring device for an internal combustion engine. The device includes an air flow meter located in an intake air path of the internal combustion engine, to measure the volume of intake air into the combustion chamber of the internal combustion engine based on an output signal of the air flow meter. The output signal of the air flow meter (AFM signal) is sampled in synchronism with the crank angle of the internal combustion engine. With this angle-synchronous processing, the device is capable of obtaining AFM data at equal intervals within a cycle of intake air pulsation, thereby eliminating adverse effects of the intake air pulsation. The device is hence capable of reducing variations in AFM data averages and calculating average flow rates of the intake air with high precision.

An information management apparatus for managing data includes a rewritable nonvolatile memory, and a memory controller configured to control inputting information into and outputting information from the nonvolatile memory. The memory controller overwrites a data, which includes a first validity check information, a first data body, a second validity check information, a second data body having the same data as the first data body and a third validity check information arranged in this order, in a designated address area in the nonvolatile memory when the memory controller performs a writing control in which the memory controller writes data in the nonvolatile memory.
