摘要： A sheet conveying device includes a pair of rollers, a biasing member, a guide member, a biasing support, and a biasing force changer. The pair of rollers includes a first roller and a second roller disposed in contact with the first roller. The pair of rollers is configured to hold a sheet between the first roller and the second roller. The biasing member is configured to bias the first roller toward the second roller. The biasing support is configured to support the biasing member and has a guide target member configured to slide along the guide member to move the biasing support. The biasing force changer is configured to change a biasing force of the biasing member along with movement of the biasing support. The guide target member has a portion projecting into a sheet conveyance passage through which the sheet is conveyed by the pair of rollers.

摘要： A sheet conveying device includes a pair of rollers including a first roller and a second roller to hold a sheet conveyed between the first and second rollers; a biasing member to bias the first roller toward the second roller; a biasing force changer to change a biasing force of the biasing member; control circuitry to, when a predetermined changing condition is met, cause the changer to change the biasing force and cause the rollers to convey the sheet; an operation detector to detect a changing operation of the changer; and a notification device to notify an abnormality of the changing operation when the operation detector detects the abnormality. When the operation detector detects the abnormality, the control circuitry performs sheet conveyance control to cause the rollers to convey the sheet without causing the changer to change the biasing force, regardless of whether the predetermined changing condition is met.

摘要： A method for using a film formation apparatus for a semiconductor process to form a thin film on a target substrate while supplying a film formation reactive gas from a first nozzle inside a reaction chamber includes performing a cleaning process to remove a by-product film deposited inside the reaction chamber and the first nozzle, in a state where the reaction chamber does not accommodate the target substrate. The cleaning process includes, in order, an etching step of supplying a cleaning reactive gas for etching the by-product film into the reaction chamber, and activating the cleaning reactive gas, thereby etching the by-product film, and an exhaust step of stopping supply of the cleaning reactive gas and exhausting gas from inside the reaction chamber. The etching step is arranged to use conditions that cause the cleaning reactive gas supplied in the reaction chamber to flow into the first nozzle.

摘要： A control unit heats a reaction pipe to a load temperature by controlling a temperature-raising heater 16, and then makes semiconductor wafers received in the reaction pipe. Next, the control unit heats the reaction pipe in which the semiconductor wafers are received to a film formation temperature by controlling the temperature-raising heater, and then forms thin films on the semiconductor wafers by supplying a film forming gas into the reaction pipe from a process gas introducing pipe. Also, the control unit sets the load temperature to a temperature higher than the film formation temperature.

摘要： A detector circuit for detecting degradation in the distortion characteristics of a power amplifier based on signals from both ends of a coupled line of a directional coupler. The detector circuit includes a phase shifter/attenuator for phase shifting and attenuating a signal from a coupled terminal of the coupled line, a differential amplifier for outputting difference between an output signal from the phase shifter/attenuator and a signal from the isolated terminal of the coupled line, a wave detector circuit for converting the difference into a DC signal, and a comparing circuit for determining whether the voltage level of the DC signal exceeds a predetermined level. When degradation in the distortion characteristics of the power amplifier arises, the phase shifter/attenuator phase shifts the signal from the coupled terminal and outputs a signal 180° out of phase with the signal from the isolated terminal.
