Patent number: 6421477Abstract: To make an optical switch smaller, two frames are formed by etching in such manner that when they are stuck together to form a support member, an hexagonal opening appears. The end portions of a pair of fixed optical fibers are arranged in the bottom portions of a pair of opposing V-grooves provided in this hexagonal opening. A pair of movable optical fibers are fixed at the other end of the support member, and these movable optical fibers are arranged in such manner that their end faces are contiguous with the end faces of the pair of fixed optical fibers. A drive mechanism causes the end portions of this pair of vertically arranged movable optical fibers to move to the left or the right, come into contact with the walls of respective V-grooves, slide into the bottoms of the grooves, and thereby have their cores aligned with the cores of the fixed optical fibers.Type: GrantFiled: March 10, 2000Date of Patent: July 16, 2002Assignee: Mimaki Electronic Component Co., Ltd.Inventors: Kazuhiro Hane, Toshiyuki Kasajima, Keiichi Hara

Patent number: 6252285Abstract: A solid state imaging device includes a plurality of photoelectric conversion elements arranged in an imaging area of a semiconductor substrate. Above each of the photoelectric conversion elements, a light-gathering microlens for gathering light on the photoelectric conversion element is disposed. Further, a microlens for shape inspection having the same shape as that of the light-gathering microlens is disposed outside the imaging area. A base pattern for inspection is disposed below the microlens for shape inspection. The shape of the microlens for shape inspection is inspected through observing an image of the base pattern through the microlens for shape inspection. A result of this inspection applies as it is to the light-gathering microlenses.Type: GrantFiled: April 8, 1999Date of Patent: June 26, 2001Assignees: NEC Corporation, Toppan Printing Co., Ltd.Inventors: Masayuki Furumiya, Yasutaka Nakashiba, Tohru Yamada, Katsumi Yamamoto, Keiichi Hara

Patent number: 5603752Abstract: An electrostatic precipitator includes a dust-collecting electrode group and a discharge electrode group arranged in the recited order with respect to the gas flow direction of a gas to be treated in the electrostatic precipitator. The discharge electrode group includes a plurality of discharge electrodes, each of which is made of a rectangular metal plate. The longitudinal edges of each plate form semicircles, with a series of saw-toothed portions having tips protruding from between each pair of semicircles. The dust-collecting electrode group includes a plurality of dust-collecting electrodes, each of which is made of a chain suspended adjacent the discharge electrode group at a predetermined spacing. The chains of the dust-collecting electrode groups are suspended so that they can rock back and forth.Type: GrantFiled: May 31, 1995Date of Patent: February 18, 1997Assignee: Filtration Japan Co., Ltd.Inventor: Keiichi Hara

Patent number: 5547496Abstract: An electrostatic precipitator has a plurality of arrays of spaced parallel dust-collecting electrodes, and at least one array of spaced parallel discharge electrodes, each array of discharge electrodes is arranged between an adjacent pair of arrays of dust-collecting electrodes. Each array of dust-collecting electrodes and each array of discharge electrodes are arranged such that the faces of the dust-collecting and discharge electrodes are parallel to each other, and parallel to the flow direction of a gas to be treated. The spacing between the dust-collecting electrodes of an array of dust-collecting electrodes, and the spacing between the discharge electrodes of an array of discharge electrodes may be sequentially narrowed from the upstream side of the electrostatic precipitator to the downstream side of the electrostatic precipitator.Type: GrantFiled: January 30, 1995Date of Patent: August 20, 1996Assignee: Filtration Japan Co., Ltd.Inventor: Keiichi Hara

Patent number: 5241465Abstract: In a method for determining an optimum scheduling in a computer-aided scheduling system the data associated with a schedule to be generated is previously stored in a memory data. A strategy decision table showing therein one or more scheduling strategies suitable for a plurality of the states in a scheduling process is prepared. An optimization definition table indicating degree of improvement precedence or precedence order of the scheduling strategies of the evaluation items, where degree of improvement precedence is defined as degree of improvement of evaluation value of he evaluation item in changing of the scheduled strategy, is prepared. A schedule is generated by repetition of selecting and executing the scheduling strategies by using the strategy decision table. The other schedules are generated by changing the scheduling strategy selected in the state of the scheduling process by using the optimization definition table. An optimum schedule having the best evaluation value is selected.Type: GrantFiled: April 23, 1991Date of Patent: August 31, 1993Assignees: Hitachi Ltd., Hitachi Microcomputer System Ltd.Inventors: Michiko Oba, Norihisa Komoda, Kazuhiro Kawashima, Keiichi Hara
