Abstract: PURPOSE:To correct an error in a rotational angle detection result by detecting the quantity of transmitted light in irradiation light from a light source and detecting the run-out of a rotary shaft from the run-out of a run-out detection pattern provided to a rotary disk. CONSTITUTION:When the rotary shaft 1 has a run-out, the run-out detection pattern 2b on the rotary disk 2 also has a run-out, so the quantity of the transmitted light in the irradiation light from the light source 3 varies according to the run-out of the run-out detection pattern 2b.

Abstract: PROBLEM TO BE SOLVED: To alleviate clogging between fins in a heat exchanger as a condenser of a refrigerator installed outdoor of a body of a vending machine or the like. SOLUTION: The heat exchanger comprises many plate-like fins 10 aligned in parallel, and a plurality of tubes 12 penetrating the fins and distributing a refrigerant therein. In this case, the fins 10 each provides an upward oblique end face 15 and a plurality of dust adherence alleviating units 14 each having a downward horizontal end face 16 disposed directly under the end face 15 at an air flow side end face 13, and an overall air flow side end face is formed in a sawtooth state. Most of the dusts in the air flowing between the fins 10 brought into contact with the upward oblique end face is introduced between the fins 10 while flowing along the oblique surface, and passed. The dusts are scarcely deposited on the downward horizontal end face, but even by depositing, the dusts are dropped by means of its gravity.  The downward horizontal end face performs a role of a by-pass of the air flow indicated by an arrow with a broken line in the case of clogging between the fins due to deposit of the dusts on the upward oblique end face in a long period. Thus, the clogging in a long period can be prevented.
