Patent number: 11911891Abstract: An actuator system that picks up workpieces aims to shorten tact time and to reduce damages to workpieces. The actuator system includes an actuator that picks up a workpiece, an external force detection sensor that detects a physical quantity that is correlated with an external force that is applied to the workpiece, a head unit that is connected to the actuator and the external force detection sensor without a communication network, the head unit being configured to control the actuator based on a sensing result from the external force detection sensor when a pickup request signal that is a signal requesting pickup of the workpiece is received, and a control device that is connected to the head unit over the communication network, the control device being configured to transmit the pickup request signal to the head unit.Type: GrantFiled: October 17, 2019Date of Patent: February 27, 2024Assignee: THK CO., LTD.Inventors: Katsuya Fukushima, Masashi Ishii, Hiroki Niwa, Akira Suzuki, Kazuto Oga, Shogo Wakuta, Satoshi Hara, Tomofumi Mizuno, Shigeki Hayashi

Patent number: 6787349Abstract: The present invention provides a high-sensitive, inexpensive biochip reader for reading a biochip as compared to a fluorescence method. The biochip reader is provided with an X-Y stage (3) for mounting a biochip (6) and scanning the biochip (6) in a two-dimensional manner, a controller (4) for the X-Y stage, a magnetic sensor (1) for reading the magnetic field strength, an ohmmeter (2), and a computer (5) for signal processing. As a result, a high-performance, inexpensive biochip reader can be provided without using an expensive laser or an expensive optical system, by employing a magnetic sensor and a disk driving mechanism generally used in a hard disk drive and the like.Type: GrantFiled: July 19, 2001Date of Patent: September 7, 2004Assignee: Hitachi Software Engineering Co., Ltd.Inventors: Kenji Yamamoto, Mitsuhiro Tachibana, Katsuya Mizuno

Patent number: 6690461Abstract: A method for displaying microarray information by which unknown but useful information is extracted from a mass amount of sample information obtained with microarrays. Luminescent intensity information of sample spots obtained with the microarrays is standardized for each microarray and displayed as a graph as a difference from the standardized luminescent intensity of a sample spot of interest. Accordingly, information can be compared without being influenced by a difference of experiment status between the microarrays or a difference of physical properties between the samples. A three-dimensional graph is displayed by sorting the set of samples and the set of microarrays to which the sample spots belong, under predetermined conditions, and assigning the set of sorted samples and the set of sorted microarrays to X-axis and Y-axis, and the accumulated luminescence intensity to Z-axis.Type: GrantFiled: March 27, 2001Date of Patent: February 10, 2004Assignee: Hitachi Software Engineering Co., Ltd.Inventors: Takuro Tamura, Jyunji Yoshii, Katsuya Mizuno

Patent number: 6589740Abstract: The present invention detects and quantities only specific hybridization bindings. A biochip 10 which is spotted with a plurality of probe biopolymers is accommodated in a container 20 into which a washing solution is supplied from a liquid supplying unit 23. A heat block 31 controls the temperature of the biochip according to a predetermined time pattern. A pickup unit 55 picks up an image of the spot surface of the biochip at predetermined pickup intervals. The plurality of images picked up with the pickup unit are stored in a computer 40. By analyzing the images for individual spots, hybridization can be detected with high reliability for every spots without being influenced by optimal hybridization temperatures which differ depending upon the types of probes on the spots.Type: GrantFiled: March 9, 2001Date of Patent: July 8, 2003Assignee: Hitachi Software Engineering Co., Ltd.Inventors: Motonao Nakao, Kenji Yamamoto, Junji Yoshii, Katsuya Mizuno

Patent number: 4493644Abstract: An improved device for measuring an inclination angle of the tapered surface of a plaster die duplicated from the prepared tooth in the field of restorative dentistry is disclosed. The device is used also for scraping operation for the was pattern. It includes a turnable tool holding plate which is turnably held in a slot formed on the lower part of a core so as to turn about a support shaft. A rotary ring with its lower end face cut to a predetermined inclination angle, for instance, 7 degrees is rotatably fitted onto the core in such a manner that the lower inclined face comes in contact with the upper faces of wing-shaped lateral projections of the tool holding plate with a transversely extending shaft disposed therebetween. The transversely extending shaft is inserted through the tool holding plate at the same inclination angle as that of the lower inclined end face of the rotary ring so that its axis intersects with the axis of the support shaft.Type: GrantFiled: November 2, 1983Date of Patent: January 15, 1985Assignee: Sankin Kogyo Kabushiki KaishaInventors: Minoru Ai, Akira Manabe, Yoshimasa Igarashi, Katsuya Mizuno
