Abstract: According to one embodiment, a sensor device is a sensor device that detects an acetyl compound in a sample and includes a storage unit that stores a sample, a sensor section that comes into contact with the sample in the storage unit and detects a change in ion density, and an amino compound fixed to the sensor section.

Abstract: An aquaculture system (Sy) includes mineral sensors (22, 24, 26) for detecting the concentrations of minerals contained in rearing water within a rearing tank (50) for rearing an aquatic organism or the rearing water within a circulation passage (70), and an adjustment section which performs instruction issuance or operation for rendering the concentrations of the minerals contained in the rearing water coincident with their standards when the mineral concentrations detected by the mineral sensors (22, 24, 26) deviate from their standards.

Abstract: In a produce management system (1), a production-base-side apparatus (10) outputs management data generated or input in a process of breeding produce at a production base. A management-base-side apparatus (70) stores or outputs at least one of the management data, a piece of relevant information generated as a result of processing or inspection of the management data, and a piece of certification information generated in response to obtainment of the management data, when the management-base-side apparatus obtains the management data.

Abstract: A humidifying device includes a casing that defines a first air passage that guides air to an adsorbent module accommodation portion accommodating an adsorbent module including an adsorbent, and a second air passage through which the air flowing out of the adsorbent module accommodation portion flows. The humidifying device includes a peltier device that has a heat absorbing side and a heat generating side generating heat due to heat transfer from the heat absorbing side. The peltier device is housed in the casing such that the heat generating side is located in the first air passage and the heat absorbing side is located in the second air passage.

Abstract: The present invention provides a plant disease control agent which is stable and safe in terms of leaving no residue and a method for controlling plant diseases using the same. The plant disease control agent comprises a fragment of an inky cap mushroom, and plant diseases are controlled by using the plant disease control agent. The plant disease control agent may be a suspension comprising the fragment of the inky cap mushroom or a solid material composed of the suspension and a carrier to which the suspension is absorbed. The inky cap mushroom is preferably Coprinus curtus or the like, especially preferably Coprinus curtus GM-21 (NITE BP-37).

Abstract: A blower includes a casing for defining an air passage through which air is blown into a compartment, a fan located in the casing to generate an air flow in the casing, a motor for driving the fan, a motor control device for controlling a rotation speed of the motor, and a heat sink located to radiate heat of the motor control device to air flowing in the air passage. The heat sink having a radiation fin is exposed into the air passage, and at least one of the motor control device and the heat sink is thermally connected to the yoke of the motor.

Abstract: A high-frequency oscillator including an oscillation circuit (1) having a quartz crystal (X) and an amplifying element (Q.sub.2), a power amplifying circuit (3) for amplifying the output of the oscillation circuit, and a control system (Q.sub.7, 6) for varying a bias voltage of the amplifying element to thereby control the output power of the power amplification circuit. The control system comprises an FET (Q.sub.7) connected at the drain thereof to the amplifying element, and a control circuit (6) for applying a control signal to the gate of the FET.
