Publication number: 20230013900Abstract: A chamber in which heating treatment is performed by irradiating a semiconductor wafer with light and a combustible gas supply source are connected in communication with each other by a combustible gas supply pipe. An electrical flow rate controller for regulating a supply flow rate of a combustible gas, and the like are interposed in the combustible gas supply pipe. Part of the combustible gas supply pipe which includes the electrical flow rate controller and the like that can be an ignition source is surrounded by an inner enclosure. Nitrogen which is a noncombustible gas is supplied to an inner space inside the inner enclosure. The noncombustible gas is supplied to the inner space, and a gas remaining in the inner space is discharged, whereby the concentration of oxygen in the inner space is decreased to below an explosion limit. This prevents fires and explosions of the combustible gas.Type: ApplicationFiled: February 2, 2021Publication date: January 19, 2023Inventor: Satoshi SEGAWA

Patent number: 9740648Abstract: A valve control unit includes a data reading/selecting unit, which reads each of signals transmitted onto a serial bus, and selects a flow rate data signal from among the read signals. Therefore, the valve control unit can acquire the flow rate data signal from the serial bus without allowing the flow rate data signal to pass via the master IC. As a result, it is made possible to ensure real time properties of feedback control, which adjusts a needle valve based on a measurement result of a flowmeter, while reducing a load applied to a CPU that controls the master IC. Moreover, it is not necessary to provide an additional instrument for transferring analog signals between slave devices, and accordingly, a size increase and cost increase of an apparatus can be suppressed.Type: GrantFiled: January 13, 2015Date of Patent: August 22, 2017Assignee: SCREEN Holdings Co., Ltd.Inventors: Takuya Miyashita, Satoshi Segawa, Naoyuki Osada

Patent number: 9020718Abstract: A torque converter (1) connecting an engine (14) and a transmission (15) of a vehicle is provided with a lockup clutch (2), and a controller (5) is programmed to increase an engagement force of a lockup clutch (2) under open loop control before shifting to feedback control of the engaging force using a target slip rotation speed. When an engine output torque rapidly decreases during open loop control (S59, S60), the controller (5) decreases the engaging force according to a variation amount of the engine output torque (S61, S65), thereby preventing an unintentional sudden engagement of the lockup clutch (2) due to decrease in the engine output torque.Type: GrantFiled: June 28, 2006Date of Patent: April 28, 2015Assignee: Nissan Motor Co., Ltd.Inventors: Yuji Katsumata, Satoshi Segawa
