Abstract: A cultivation greenhouse includes: an inner lining that forms a housing space for housing a plant to be a cultivation target, the inner lining tightly sealing the housing space; an outer lining that is disposed on an outer side of the inner lining to house the inner lining, the outer lining forming, with the inner lining, a circulation space for flowing outside air; and a circulation device that circulates air outside the outer lining into the circulation space and discharges the air to outside of the outer lining.

Abstract: A vehicle diagnosis system has: a diagnosis unit that diagnoses an abnormality of a part separating the inside and the outside of a vehicle cabin in a vehicle; an alarm and a horn located outside the vehicle cabin; and a microphone located inside the vehicle cabin. The diagnosis unit executes an acquisition process of, when the alarm or the horn emits a sound, acquiring detected sound data about the sound as detected by the microphone, and a determination process of determining whether the part has an abnormality by comparing the detected sound data with predetermined reference sound data.

Abstract: A vehicle lower structure includes a plate-shaped under cover configured to be attached to a lower section of a vehicle to form a part of an underside of the vehicle, and an air-permeable sound-absorbing member, which is attached to an upper surface of the under cover. The under cover includes one or more vent holes extending through the under cover in a thickness direction. The sound-absorbing member is attached to the under cover so as to close the one or more vent holes.

Abstract: A content recording apparatus includes a light-receiving circuit, and a remote controller signal from a TV-use remote controller is received by the light-receiving circuit. When a channel selecting operation is carried out by the TV-use remote controller, reception channels of both a television receiver and a hard disk video recorder (tuner circuit) are changed. Then, in the hard disk video recorder, a TV program received at the reception channel is recorded into a hard disk.

Abstract: A drop out compensation circuit for resolving the unnaturalness of the pictorial image due to a long period drop out compensation is disclosed. This drop out compensation circuit comprises a drop out detecting circuit, a delay circuit for delaying a drop out detected output, and a circuit for limiting the drop out compensation to the delay time period by the delay circuit in response to the drop out detected output and the delay signal of the delay circuit. Accordingly, the drop out compensation is performed only within a range wherein it is visually natural, so that unnatural pictorial image does not appear.
