Patent number: 7383156Abstract: It is possible to inspect scratches and staining on a wafer surface on the basis of an LPD map obtained from a particle counter 11, by providing a means 21 for detecting aggregation of clustered point defects (LPD) from two-dimensional distribution information 30 for such fine LPD on the surface of a silicon wafer, and an improvement in the inspection efficiency and the precision of judgements of “defective” status can be achieved. Furthermore, the system is devised so that the trend of generation of scratches and staining in a specified process can easily be detected by accumulating wafer surface information such as scratch information, staining information and the like for the wafer surface detected by a wafer surface inspection device 11 (especially as image information or numerical information), and superposing sets of information thus accumulated. Plans for improving processes can be made by both the wafer supplier and wafer consumer by sharing such information with both parties.Type: GrantFiled: September 5, 2001Date of Patent: June 3, 2008Assignee: Sumco Techxiv Kabushiki KaishaInventors: Kouzou Matsusita, Yukinori Matsumura, Tomikazu Tanuki, Mitsuo Terada, Kotaro Hori, Kiyoharu Miyakawa, Akira Nisi, Hirobumi Miwa

Patent number: 6143256Abstract: The invention provides an ozone generator controlling apparatus capable of controlling an ozone generator so that when a discharge breakdown occurs in some discharge element, the operation of generating ozone can be continued without imposing a bad influence on the remaining normal discharge elements. When an anomaly occurs in one of or a plurality of discharge elements during the operation of generating ozone, the anomaly is detected by an anomaly detection means. In response to the detection of the anomaly, first output control means reduces the output of an AC power supply circuit to a sufficiently low level so that after the discharge element having the anomaly is isolated from the circuit the operation of generating ozone can be continued with the remaining normal discharge elements without interruption and without causing the normal discharge elements to encounter an overload current thus preventing them from being broken one after another.Type: GrantFiled: June 11, 1998Date of Patent: November 7, 2000Assignee: Kabushiki Kaisha Kobe Seiko ShoInventors: Misato Shinagawa, Takashi Tanioka, Mitsuo Terada, Yoshiyuki Nishimura

Patent number: 5882609Abstract: An ozone production apparatus for increasing ozone generation efficiency by improving ceramic plate cooling efficiency. An ozonizer of this invention has a steel plate shaped body for use as a discharge electrode through which gas is permeable from one surface to another. This discharge electrode is faced on both sides by two ceramic plates, with a material gas flow inlet provided on one side and an ozone flow outlet on the other side. The ozonizer unit is provided with an insulated waterproof cable for applying a high voltage to the discharge electrode. This ozonizer unit is submerged inside a cooling water tank, and a high voltage, high frequency power supply unit is connected between the discharge electrode and the cooling water, with the cooling water tank as the grounded side. In this manner, since the ozonizer unit is submerged inside the cooling water tank, the cooling efficiency is improved and the ozone generation increased.Type: GrantFiled: March 6, 1996Date of Patent: March 16, 1999Assignee: Kabushiki Kaisha Kobe Seiko ShoInventors: Hirokazu Shiota, Mitsuo Terada, Hiromi Kihara, Yoshiyuki Nishimura, Takashi Tanioka

Patent number: 5564635Abstract: According to the present invention there are provided a method and an apparatus capable of disintegrating used paper into long pulp fibers without tearing it mechanically. In the apparatus, a wall surface having an undulating section is formed on an inner side of a gas flow path, with a current of air having a velocity component parallel to the wall surface and a velocity component perpendicular to and striking against the wall surface is allowed to pass through the gas flow path. Finely cut used paper pieces are allowed to pass through the gas flow path while being carried by the air current. The parallel velocity component of the air current is set at 40 m or more. An impeller is mounted within a circular casing body having an inlet port and an outlet port, and undulating teeth are formed on the inner peripheral surface of the circular casing body. The used paper, which is sucked in from the above inlet port together with the air current, is cut beforehand into pieces.Type: GrantFiled: September 28, 1994Date of Patent: October 15, 1996Assignee: Kabushiki Kaisha Kobe Seiko ShoInventors: Mitsuo Terada, Satoshi Kiyose, Tetsuro Matsumoto, Hiroyuki Tanaka, Takeshi Inaba, Hisanori Shimakura, Hirokazu Shiota
