摘要： An optical encoder includes a light source for emitting coherent parallel light and a scale having a grating track for defracting parallel light emitted from the light source. The grating track of the scale includes a plurality of linear adjacent gratings extending in a lengthwise direction. Each of the gratings extends in a widthwise direction direction to define a pitch of the grating. Each grating includes a non-transmitting portion and an adjacent transmitting portion extending in lengthwise direction. The aperture ratio defined by the ratio between a width of the transmitting portion and the pitch of each grating is substantially constant for each of the gratings along the grating track. However, the pitch of each of the gratings of the grating track varies along the grating track. A light spot positioning detector is provided for receiving positive and negative defracted light beams of a same order defracted from a grating track for determining a position of the scale.

摘要： This invention concerns an improvement for the structure of a rotor attachment in a permanent magnet type synchronous motor. This invention can effectively prevent axial displacement or peeling off of the magnets which might otherwise be caused by insufficient adhesion or deterioration of adhesives by the unique structure of attaching magnets to the rotor shaft as side plates having grooves are fixed to both sides of magnets adhered to a shaft to engage with at least one end face of magnets and the outer peripheries of the side plates and the magnets are wound with non-magnetic fibers for securing, thereby greatly enhancing the reliability of the motor.

摘要： In a method for processing animated graphic in which a graphic symbol is displayed on a displaying unit on the basis of data preliminarily set in a video RAM and the displayed graphic symbol is totally shifted by a predetermined amount, the graphic symbol to be shifted is initially described in an original graphics storing area and a graphic symbol transfer area is provided so as to include the graphic symbol initially described in the original graphics storing area and includes a non-display area at the outer periphery thereof. The data corresponding to the transfer area is then transferred into the video RAM the transferred data including the sizes or dimensions and the coordinate of the reference point of the transfer area.

摘要： A numerical control information generating apparatus has a function of automatically correcting machining conditions by calculating corrected machining conditions from corrected numerical control information. The apparatus also has a valid/invalid setting function of automatically correcting machining conditions for the purpose of allowing an operator to select at will the conditions under which the function of automatically correcting machining condition works, and a numerical control information correcting section, in which a machining conditions automatic correction command is provided, so as to perform machining conditions automatic correction at any time as required. As a result, since machining conditions are corrected automatically by correcting numerical control information, an operator can set proper machining conditions easily even if the operator does not understand the relationship between the machining conditions and the generated numericaL control information.
摘要翻译：数值控制信息生成装置具有通过从校正的数值控制信息计算校正的加工条件来自动校正加工条件的功能。该设备还具有自动校正加工条件的有效/无效设置功能，用于允许操作者随意选择自动校正加工条件的功能的条件工作，以及数字控制信息校正部分，其中提供加工条件自动校正命令，以便根据需要随时执行加工条件自动校正。结果，由于通过校正数值控制信息来自动校正加工条件，所以即使操作者不了解加工条件与生成的数字控制信息之间的关系，操作者也可以容易地设定适当的加工条件。
