Patent JP-H03282009-A (JP)
Title: Bearing device and manufacture thereof
Inventor: OSANAWA TAKASHI
IPC: F16C33/14
Filed: 1990-03-28
Abstract: PURPOSE:To cheaply manufacture a bearing device on the sliding surface of which plural spiral grooves are provided so that the widths of the grooves gradually become narrow toward the center by firstly pressing the sliding surface by a die having projected parts formed by reversing the grooves, and then pressing it by a die having a smooth pressing part. CONSTITUTION:On the sliding surface 1a of the thrust bearing 1 of a bearing device, curved dynamic pressure generating grooves 2 which radially circulate from the center toward the outer periphery are provided. A number of dynamic pressure generating grooves 2 are regularly arranged, and the widths 6 are narrowed gradually in the direction A of rotation and the depths are uniform. A fluid in the dynamic pressure generating grooves generates dynamic pressure by pumping action of the grooves due to their rotation. In order to manufacture the grooves, the sliding surface 1a of the thrust bearing 1 is pressed by a die having projected parts in a shape formed by reversing the dynamic pressure generating grooves 2, and thus the grooves are transfered on the sliding surface. In the projected parts, the outer peripheral parts ar lower, and the bottoms of the grooves are almost equally deepened due to elastic deformation during pressing operation. The sliding surface is then pressed by a die having a smooth surface. The bearing device can thus be easily and cheaply produced by plastic working.

Title: Confirming method for coordinate input of crt device
Inventor: SHIRAKO MUNEHARU
IPC: G06F3/048
Filed: 1986-04-03
Abstract: PURPOSE:To obtain the same effect as that secured with a command for 'execution' or 'cancel' of processing just with an indicating operation of coordinates, by deciding the indication for 'execution' or 'cancel' according to the time width of indication. CONSTITUTION:The touch coordinates are read out and this coordinate area is displayed by flickering when a finger touches the number 2 for selection of a spot graphic picture while a CRT picture of a picture menu is displayed. As a result, the CRT picture is flickering at a point of the number 2. Then a counting action is started to add f1 to a counter and it is decided whether the touch input is intermittent or not. If the touch input is intermittent, the count value of the counter is increased. It is checked whether the count value of the counter is equal or not to >=1sec after no touch input is decided with release of a finger. Then the counter is cleared to zero if the count value of the counter is larger than 1sec. Then the picture display is processed in response to the read coordinates. Thus the CRT picture is changed to a spot graph.

The discrimination processing device 9 finds the hue angles 6 of the picture elements, when the saturations 7 of the picture elements are more than the threshold value and compares with and refers to the corresponding relation of the hue angle scope of the copper, and when the hue angle 6 is within the specific scope, the picture elements are decided to be the copper. When the hue angle 6 is not within the scope, it is decided not to be the copper, and when the saturation 8 is less than a threshold value, it is decided not to be the copper. And when the ratio of the total area of individual scraps, and the copper area in the image area the scraps occupy is a threshold value or higher, it is decided to be the copper including scraps.
