The element lens 11 emits the luminous flux in such a manner that the center of the luminance flux makes an angle θ11 with respect to the optical axis La of the entire system. Similarly, the element lens 12 emits the luminous flux in such a manner that the center of the luminous flux makes an angle θ12. The center-of-mass position of the luminous flux on each secondary light source surface differs from the array of the element lenses 11, 12 constituting the integrator 1.

Title: Method and device for extracting electric symbol from construction drawing
Inventor: ONO HIROAKI
IPC: G06T7/00
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To automatically extract electric symbol entered into a construction drawing with high precision by finding the circularity of an outline as to an image in image data whose outline data size is within a specific range, and extracting outline data whose circularity is larger than a threshold value as an electric signal. SOLUTION: An image read part 2 reads an interior electric drawing as one kind of construction drawing to input its image data, and stores the image data in a memory 4 after skew correction. As for the image data on the interior electric drawing stored in the memory 4, data indicating the start point and end point of black pixels which continue in a horizontal scanning direction is generated as black run data by one-pixel width in a vertical scanning direction. Then the outline of a black pixel part (image) is found from the black run data to generate outline data, and outline data whose horizontal and vertical fillet lengths are less than threshold values are left. Then the circularity of the remaining outline data is found and outline data having circularity larger than a threshold value are regarded as an electric signal.

Abstract: PURPOSE:To improve accuracy as a sensor for an encoder and to manufacture a high resolution magnetic encoder, by selecting a target voltage and a substrate temperature, forming a Permalloy film on an insulating substrate, and patterning the film in a stripe pattern having a specified width. CONSTITUTION:A Permalloy film is formed on an insulating substrate 2, which is kept at 250-450 deg.C under the condition of a target voltage of -250--750V. The film is patterned in a stripe shape having a width of 5-30mum. For example, a cleaned boron silicate glass substrate 2 is set in a sputtering apparatus. Thereafter, the substrate 2 is heated with a seeds heater, and a film of a thickness of 500Angstrom  is formed at a specified temperature. At this time, the partial pressure of Argon in sputtering and the like is set at 5-9X10<-3>Torr and a distance between the target and the substrate is made to be 50mm. The film is formed by changing a target material, the target voltage, a current and the substrate temperature as factors influencing the conditions for forming an Fe-Ni film. A pattern having the widths of 5, 10, 15, 20 and 30mum and the length of 500mum is formed by photolithography. Thus a high resolution magnetic encoder can be obtained.

Title: Method and device for controlling overall writing length in led print bar
Inventor: JIYOOJI EI CHIYAANITSUKI
IPC: B41J2/44
Filed: 1992-10-02
Abstract: PURPOSE: To provide a printing system using a LED print bar capable of correcting the change in length caused by the fluctuation of temperature. CONSTITUTION: Overall length of LED print bars 40, 42, 44 arranged in a single pass printing system is controlled by controlling the operating temperature of the LED arrays 40A, 42A, 44A forming the light emitting portion of the print bar. Rather trying to maintain the arrays at some predetermined temperature, the array temperatures are allowed to vary over a predetermined range but within this range, the arrays are all at the same temperature. This is accomplished by mounting the arrays on a common subframe 50 which is adapted to circulate a cooling medium through each of arrays in parallel rather than in series. Thus, each array is cooled at the same rate and will attain the same equilbrium temperature, thus ensuring that registration will be accomplished within each single pass operation.
