Title: Pattern retrieving system
Inventor: SUGA YOSHIO
IPC: G06T11/80
Filed: 1988-05-18
Abstract: PURPOSE:To retrieve the patterns within an optional polygonal area at the side of a display device by adding a simple circuit to the display device. CONSTITUTION:A retrieved polygonal area is stored in a memory means 10. For instance, a command is received from a host CPU 2 for definition of an area. Based on this command, an address designating means 9 transmits the pixel addresses of each side of the retrieved polygonal area. This polygonal area in the means 10 is filled with the value showing the area to be retrieved via those pixel addresses. When a pattern is retrieved, the means 9 delivers the pixel addresses of each side of a pattern to be retrieved based on the graphic data stored in a graphic display device 1. A retrieval control means 11 reads the contents of the means 10 based on said pixel addresses and decides whether the subject pattern is set within a retrieved area or not. If so, the means 11 transmits a detecting signal. Thus it is possible to retrieve the patterns within an optional polygonal area at the side of the device 1.

Title: Automatic focus adjusting method
Inventor: MATSUI SHIYOUGO
IPC: G02B7/36
Filed: 1980-08-29
Abstract: PURPOSE:To make accurate focus adjustment while improving focus detection sensitivity by scanning a light beam on a focus detection pattern through the objective of a microscope and by converting the contrast of the observed pattern into an electric signal. CONSTITUTION:On a focus detection pattern 4 formed on the detected mirror surface of a mask base plate 1 mounted on a stage 6,a laser beam 8 reflected by a rotating mirror 8 is scanned through an objective lens 9, and the beam 8 transmitted in an area including the pattern 4 is supplied to a photoelectric converting element 14 through an optical lens 13 to be converted into an electric signal. Then, this signal is converted into a wave-height signal by a differentiating circuit 15 to detect whether the crest value increases or decreases according to the movement of the stage 6 by an electric signal processor 16. Then, a signal output system 17 controls a DC motor 5 to move the stage 6 up and down, and it is stopped where the greatest crest value is obtained, namely, where the highest contrast of the pattern 4 is obtained. Consequently, the focus detection sensitivity is improved and focus adjustment is made accurately.

Title: Method and device for measuring deformation of thin plate
Inventor: MASUYAMA SHOJI
IPC: H01L21/66
Filed: 1993-05-21
Abstract: PURPOSE:To accurately measure only the original deformation of a thin plate by dipping the thin plate to be measured in a liquid with nearly a same specific gravity as that of the thin plate or up to the liquid interface and then measuring the deformation of the thin plate. CONSTITUTION:A thin plate 3 to be measured is dipped until its upper side surface is level with the liquid interface inside a liquid container 1 and is placed on support rods 4 by suppressing the influence due to its own weight of the plate 3 itself. The deformation such as the warpage of the plate 3 is measured in this state by a measuring instrument 5. A liquid with nearly the same specific gravity as that of the plate 3 is used as a liquid 2 inside the container 1 but actually the specific gravity of the liquid is slightly smaller than that of the plate 3. In this manner, when the plate 3 is dipped in the liquid 2, buoyancy acts on the plate 3 to reduce the influence of gravity relatively, thus minimizing the influence of the deformation, etc., due to the own weight of the plate 3. It can be applied to a thin plate which is easily subjected to deformation such as warpage and deflection such as a ceramic substrate. For example, electrical and optical measuring instruments can be used for the measuring instrument 5.

Title: Regulating wheel slide for centerless grinder
Inventor: TSUJIUCHI TOSHIO
IPC: B24B5/30
Filed: 1983-07-04
Abstract: PURPOSE:To surely transmit torque even if the reaction force to the torque is reversed at the low speed of rotation, by providing a transmission mechanism on the regulating wheel shaft of a regulating wheel slide to control the rotation of the shaft, and enabling the change in the speed of a regulating wheel through the switchover of the direction of rotation of a motor. CONSTITUTION:The slow rotation of a regulating wheel 5 in the grinding of a workpiece W results in moving a stopper shaft 26 to a position where the shaft is engaged with an engage-stopping portion 29 by the elastic force of a spring 27. An input shaft 14 is rotated forward by a drive motor so that a planet gear 17 is revolved while rotating counterclockwise because a rotary member 21 is kept by a one-way clutch 23 from being turned clockwise and is kept by the stopper shaft 26 from being turned counterclockwise. As a result, a slow forward rotation under high torque is transmitted to a regulating wheel shaft through an output arm 18. When the input shaft 14 is rotated backward, the rotary member 21 is turned together with the input shaft through a one-way clutch 24 so that the rotation of the input shaft is transmitted directly to the regulating wheel shaft through the output arm 18. At that time, the transmitted rotation is a rapid backward one under low torque.

Thus, if the face photograph, personal information such as characters are altered, the laminating material must be peeled. In this case, the image recording medium is damaged together with the laminating material to cause a forgery or a falsification to be difficult.
