A micro-lens substrate having a precise micro-lens array suitable for higher resolution, the micro-lens array substrate of high quality without having a distortion, and a method for manufacturing thereof are provided. In the micro-lens array substrate of the present invention, a micro-lens array formed of a plurality of consecutive concave lens-shaped micro-lenses is directly formed in a surface of a quartz substrate or glass substrate, and the micro-lens array is formed by a transfer method based on dry-etching. In the micro-lens array substrate of the present invention, a taper portion is formed toward the surface of the substrate in a peripheral portion of the micro-lens array in the quartz substrate or glass substrate. In a method for manufacturing the micro-lens array substrate of the present invention, a resist layer having a plurality of consecutive lens-shaped concave portions is formed in a surface of a quartz or glass substrate, the lens-shaped concave portion of the resist layer is transferred to the substrate by dry-etching, and a micro-lens array is formed by injecting a resin into the lens-shaped concave portion of this substrate. In addition, a taper portion is formed in a peripheral portion similarly to the formation of the lens-shaped concave portion, and a micro-lens array is formed by injecting a resin into the lens-shaped concave portion and taper portion.

A browser is requested to display a text file having a description of a screen structure. The state information on a current state of the embedded device is acquired. An access request for requesting the browser to update, with the acquired state information, a value of at least one node in a document object model (DOM) tree generated from the text file by the browser, is submitted by a state display control program. The at least one node is recorded in an access history list. At a subsequent time, it is determined whether to permit a subsequent access request. If the source of the subsequent access request is not the state display control program, and the at least one node is recorded in the access history list, the subsequent access request is denied.

An image reading device includes: an image reading unit configured to, in a process of reciprocating relative to a fixed document, read a document image using one or a plurality of reading colors, and when a plurality of reading colors are used, read the document image while successively switching the reading colors in a process of moving; a moving unit configured to move the image reading unit; a moving speed changing unit configured to change moving speeds of the image reading unit in an outgoing path and a return path based on a number “N” (where N is a positive integer) of the reading colors by the image reading unit; and a reading color number changing unit configured to change reading color numbers of the image reading unit in the outgoing path and the return path based on the number “N” of the reading colors.
摘要:
The aim of the present invention is to estimate EDR directions in a single index model composed of a large number of variables with simple calculations without using the inverse matrix of the variance-covariance matrix and principle component analysis. Data conversion means 21 receives, from an input device 3, data to be analyzed, the data composed of sets of response variables and explanatory variables, standardizes the explanatory variables, and sends them to slice average calculating means 22. The slice average calculating means 22 divides the data into two slices with reference to the median of the response variables to calculate the mean vector of the explanatory variables on a slice basis. The calculated mean vectors are sent to EDR direction calculating means 23. The EDR direction calculating means 23 calculates the difference between the mean vectors for respective slices to estimate an EDR direction. The EDR direction calculating means 23 also corrects the estimated EDR direction using the inverse matrix of the correlation matrix of the explanatory variables, if any. Both the estimated EDR direction and the corrected EDR direction are sent to the data conversion means 21, and transformed by the data conversion means 21 into the original coordinate system.

A first loop antenna apparatus is disclosed which includes an open loop antenna portion and an inductor having a predetermined inductance and first and second ends connected to first and second intermediate points of the open loop antenna portion. The inductance of the first loop antenna apparatus is decreased because the inductor is connected in parallel, so that an opening area (antenna gain) is increased at the same resonant condition. A second loop antenna apparatus is also disclosed which includes an open loop antenna portion, a first inductor having a predetermined inductance, one end of the first inductor being connected to first intermediate point of the open loop antenna portion, a second inductor having the predetermined inductance, one end of the second inductor being connected to a second intermediate point of the open loop antenna portion, and a capacitor having a predetermined capacitance, connected the other ends of the first and second inductors. Similarly, the inductance of the second loop antenna apparatus is decreased because the inductors and the capacitor is connected in parallel, so that an opening area (antenna gain) is increased at the same resonant condition.

摘要:
A level detecting part detects image data levels for the respective output directions of the first half and the second half to be used for the linearity correction, which image data levels correspond to image data around a connection point between the first half and the second half and are obtained from respective combinations for the respective output directions of the first half and the second half. A calculating part calculates linearity correction values or correction value calculating parameters from the detected image data levels for any one of the first half and the second half; and a defect detection part detecting a defect in the image data levels thus detected around the connection point are provided.
