Abstract: <P>PROBLEM TO BE SOLVED: To photograph with a low light intensity, to reduce an image magnification, and to perform image preservation and transferring by cutting out the area in which an eye fundus image is imaged without changing sensitivity of an imaging means.  <P>SOLUTION: The eye fundus image 17b in an observation mode is imaged small relative to the effective imaging domain of an image pickup element 17a. A rectangular domain 17c including an imaging range is cut out by the following calculation method. Let the address at the upper left of the image pickup element 17a to (0, 0), the longitudinal direction to X, and the lateral direction to Y, and express the address of an image data as (X, Y).

Title: Inkjet recorder and inkjet recording method

IPC: B41J2/185
Filed: 2004-06-08
Abstract: <P>PROBLEM TO BE SOLVED: To suppress a decrease of the image quality because of such a discharging defect that makes an ink striking position different for every discharge opening although paper face spare discharging is carried out in an inkjet recorder.  <P>SOLUTION: After discharging is carried out for the first time from the discharge opening #0, discharging is carried out for the second time from the discharge opening #2 skipping one discharge opening. A sequential number of discharging increases for every other discharge opening in the same manner. Similarly, the sequential number of discharging increases for every other discharge opening from the discharge opening #1. A difference of the sequential numbers of discharging becomes large between adjacent discharge openings in a discharge opening arrangement. In consequence of this, when recording is started after the paper face spare discharging, even if the discharging defect is brought about, dots to be formed by ink from the adjacent discharge openings are formed while positionally greatly shifted by a passed time according to the difference of the discharging sequential numbers. However, the dots are visually recognized to be a thick line and incline, so that the shift becomes less noticeable in a recording image.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide a game machine capable of sufficiently securing the space for a game ball to roll, and temporarily retaining and releasing the game ball.  <P>SOLUTION: A rolling face 202 of a winning device 40 has divided inclined faces 202a and 202b, and a posture changing mechanism for changing the inclined postures of the divided inclined faces 202a and 202b so that level difference 230 for making a game ball B stay is formed. In the level difference, the end on the upstream side of the divided inclined face 202b on the downstream side is higher than the end on the downstream side of the divided inclined face 202a on the upstream side. Accordingly, when the level difference 230 is not formed, the game ball B can flow down without staying and the whole rolling face 202 can be used as the space for rolling. When the level difference 230 is formed, the game ball B can stay in the level difference 230, and the staying state of the game ball B can be released by returning the rolling face 202 from the state with the level difference to the state without the level difference. In this way, sufficient space for the game ball B to roll can be secured, and the game ball B can temporarily stay or the staying state can be released.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
