摘要:
A film deposition apparatus includes a turntable including a substrate placement region at its surface; first and second reaction gas supply parts disposed in first and second supply regions in a chamber and supplying first and second reaction gases onto the surface, respectively; a separation region disposed between the first and second supply regions, the separation region including a separation gas supply part ejecting a separation gas separating the first and second reaction gases and a ceiling surface forming a separation space to supply the separation gas to the first and second supply regions; and first and second evacuation ports provided for the first and second supply regions. At least one of the first and second evacuation ports is disposed so as to guide the separation gas, supplied to the corresponding supply region, toward and along a direction in which the corresponding reaction gas supply part extends.

An image forming apparatus includes an image bearing member; toner image formation means for forming a toner image on the image bearing member; removing means for removing deposited matter deposited on the image bearing member; detecting means for detecting a toner image to be detected, formed on the toner image formation means; control means for controlling a toner image forming condition of the toner image forming means in accordance with a result of detection of the toner image to be detected by the detecting means; the apparatus being operable in a mode in which the removing means operates to remove the deposition, and the detecting means operates to detect the toner image to be detected, executing means for executing an operation in the mode; and an operating portion for manually starting execution of the operation in the mode by the executing means.
摘要:
A substrate holder has two holder constituting bodies, each having a plurality of columns arranged on an imaginary circle, and substrate holding sections that hold circumferential portions of respective substrates. The holder constituting bodies hold the substrates so that either their front surfaces or their back surfaces face upward with a substrate having an upward facing front and a substrate having an upward facing rear being alternately arranged in a vertical direction. At least one of the holder constituting bodies moves in the vertical direction to change the positions of the holder constituting bodies relative to each other. A distance between a first pair of vertically adjacent substrates with their respective front surfaces facing each other is set to ensure treatment uniformity, and to be larger than a distance between a second pair of vertically adjacent substrates with their respective back surfaces facing each other.
摘要:
A next command reference value close to a “the value L serving as a reference” is read from its own path table, and if there is the read command reference value in its own path table, then it is determined whether or not the “the value L serving as a reference” reaches the command reference value. When the “the value L serving as a reference” reaches the command reference value, if there is a waiting command of waiting for other path table, counting of the “the value L serving as a reference” is stopped. When waiting for the other path table is completed, the stop of counting of the “the value L serving as a reference” is released, the command is executed, and processing is continued.

An image forming apparatus includes a movable image bearing member; a toner image forming unit which repeatedly forms plural toner images in the image bearing member; a detection toner image forming unit which forms a detection toner image in an inter-image area between the toner image and the toner image on the image bearing member; a transfer member which is in contact with an area in the image bearing member through intervention of a recording material, the toner image being formed in the area, the transfer member being in contact with the inter-image area with no recording material, the transfer member electrostatically transferring the toner image formed in the image bearing member to the recording material; a detecting unit which detects the detection toner image on the image bearing member; a controlling unit which variably controls a toner image forming condition of the toner image forming unit based on the detection result; and a toner removing unit which forms a cleaning electric field to remove toner adhering to the transfer member, the cleaning electric field electrostatically moving the toner adhering to the transfer member to the image bearing member while the transfer member is in contact with the inter-image area, wherein, letting a time when the toner removing unit forms the cleaning electric field be T1 in the case where the detection toner image is formed prior to the formation of the cleaning electric field in the inter-image area with which the transfer member is in contact, and letting a time when the toner removing unit forms the cleaning electric field be T2 in the case where the detection toner image is not formed in the inter-image area with which the transfer member is in contact, T1 is longer than T2.

A capacitor capacitance diagnosis device includes a power supply which is for charging a capacitor, a discharge circuit which is connected to the capacitor in parallel to discharge energy of the capacitor, a resistance dividing circuit which is for measuring voltage drop value during discharging, a measurement circuit which measures divided voltage, and a diagnosis circuit which determines adequacy of capacitor capacitance from a time change in voltage due to the discharge. This makes it possible to diagnose adequacy of capacitor capacitance of an electric power apparatus during operation.
