Title: Solid state image sensor
Inventor: MATSUMOTO KAZUYA
IPC: H04N5/355
Filed: 1991-04-01
Abstract: PURPOSE:To perform high sensitivity by providing a microlens array made of organic or inorganic material provided selectively in correspondence with each photodetecting pixel on a protective film transparent to visible light and covering a pixel array, and so disposing that its optical axis and focus exist on a high electric field application region in each pixel. CONSTITUTION:A microlens 26 is formed on each pixel, and so formed that its optical axis and a focus exist at a point A in a region 25 in which avalanche phenomenon occurs at each pixel. An incident light condensed by the microlens 26 is effectively projected onto the point A of the region. Then, photocarrier photoelectrically converted under the region A and generated thereat is multiplied in the region 25 by an avalanche effect, and stored in the boundary between an insulating film and a semiconductor under a gate electrode 22. Thus, the photocarrier can be amplified, stored, and hence its sensitivity can be improved.

Title: Shuttle body driving device for zigzagging sewing machine
Inventor: NAKAMURA MICHIHIRO
IPC: D05B3/02
Filed: 1990-04-06
Abstract: PURPOSE:To keep contact between a sewing needle and a hook point of a shuttle body in a proper state regardless of the size of the swing width of zigzagging movement of the sewing needle by providing a timing varying means to set and vary the reference position of a comparing means, based on an amount of movement in a zigzagging direction of the sewing needle by a needle point means. CONSTITUTION:A zigzagging width is set to maximum + or -26.4 deg.C (converted into the rotation angle of a shuttle body with a contact position in case of a zigzagging width being zero). When a sewing work is started by a sewing starting button, a needlebar driving motor 15 is run to start vertical movement of a needlebar 13. A needlebar swinging motor 51 is driven by means of a microcomputer 42 by a zigzagging width set amount throughout a range of rom an upper shaft rotation angle of 287 deg. to 79 deg.. When, through running of a swinging motor 51, a sewing needle 11 is swung in a lateral direction (a zigzagging direction), the rotation reference angle of a shuttle body is changed in response to a swing amount of the needle 11. The microcomputer 42 effects processing such that a swing amount (drive amount data of a neeldebar swinging motor) of a sewing needle is read and the rotation reference angle of the shuttle body responding to the swing amount is read from a conversion table previously stored in an ROM 44 to store.

Filed: 1995-04-19
Abstract: PURPOSE: To perform the proper initialization of a shape control actuator, and to prevent the lowering of yield by incorporating the crown amount of a work roll in the same position as the width direction position of a split bearing in a model expression as a factor.
