Patent number: 11898567Abstract: A deposited material sensor is arranged, in a flow path of a gas from an inlet port to an outlet port, on an upstream side or a downstream side of a predetermined flow path position where a cause of disruption to operation of the vacuum pump is to occur. In addition, the deposited material sensor detects a presence or absence of deposited material at the arrangement position of the deposited material sensor, and the arrangement position of the deposited material sensor is a position where a thickness of the deposited material at the predetermined flow path position assumes a predetermined thickness that corresponds to a maintenance time of maintenance for suppressing the cause when a detection state of the deposited material sensor changes from deposited material absent to deposited material present.Type: GrantFiled: March 9, 2020Date of Patent: February 13, 2024Assignee: Edwards Japan LimitedInventors: Hideki Enosawa, Manabu Nonaka, Takashi Kabasawa

Publication number: 20230400868Abstract: A vacuum exhaust system is provided which can reduce a size of a pump or a valve, and can thin the pipe diameter, and can perform highly efficient exhaust making the best use of exhaust characteristics of the pump from high vacuum to the large flow region. The process gas used in a vacuum chamber passes through a regulating valve, and reaches a first branch pipe. The passage on the side indicated with A in the drawing of the first branch pipe is connected with an inlet port of a second pump. On the other hand, the passage indicated with B in the drawing of the first branch pipe is provided with a bypass valve. Then, the downstream of an outlet port of the second pump and the downstream of the bypass valve are connected with a first pump via a second branch pipe. In the low and medium vacuum regions (at the time of large flow rate exhaust), the bypass valve is opened. At this time, the gas is exhausted through both the passage A including the second pump therethrough and a passage B.Type: ApplicationFiled: October 1, 2021Publication date: December 14, 2023Inventor: Manabu Nonaka

Patent number: 10662957Abstract: A vacuum pump has, in at least either a stator disc to be disposed or a rotating disc to be disposed, a Siegbahn type molecular pump portion in which a spiral-shaped groove with a ridge portion and a root portion is engraved (disposed), and is structured to ensure high conductance at a returning flow channel formed at the outer periphery (outside) of the Siegbahn type molecular pump portion. This structure is created by a communicating portion (a groove portion, a slit) formed on each rotating disc, or an oblique plate disposed on the stator disc and the communicating portion formed on the rotating disc. The “communicating portion,” “groove portion,” and “slit” are configured to have “concave” shapes, a concave portion is provided by engraving a groove radially inward from an outer diameter portion (toward a side of a shaft of the vacuum pump) in the rotating disc (or stator disc).Type: GrantFiled: October 29, 2014Date of Patent: May 26, 2020Assignee: Edwards Japan LimitedInventors: Manabu Nonaka, Takashi Kabasawa

Patent number: 10578158Abstract: Provided are a vacuum pump and a method for the vacuum pump in which, when contact between a rotating body and a stator is sensed, the cause of the contact can be analyzed. Contact determination is made using a threshold for rotating body contact determination for a displacement signal and a threshold for rotating body contact determination for an acceleration signal. The amount of unbalance of a rotating body is determined using a threshold for amount-of-unbalance increase determination for the displacement signal and a threshold for amount-of-unbalance increase determination for the acceleration signal. When, in one of the displacement signal and the acceleration signal, the threshold for amount-of-unbalance increase determination or the threshold for amount-of-unbalance increase determination is exceeded within a predetermined time before determination of an estimated time point of contact, the contact is determined not to be caused by an increase in accumulation of products.Type: GrantFiled: November 5, 2015Date of Patent: March 3, 2020Assignee: Edwards Japan LimitedInventors: Yoshinobu Ohtachi, Yasushi Maejima, Tsutomu Takaada, Manabu Nonaka
