Title: Area calculating method for closed area including circular arc
Inventor: IMAI SATORU
IPC: G06F17/50
Filed: 1987-12-16
Abstract: PURPOSE:To simplify processing logic and to shorten processing time by retrieving a circular arc along a closed area, adding a code corresponding to the direction the circular arc against the direction of the retrieval to the area of the circular arc, and adding the result to the area of the area less arc-area. CONSTITUTION:As shown in the figure B, the area excluding the circular arc area from contour line data is calculated, and the areal calculation of the circular arc area is executed as follow: assuming the retrieval direction of the circular arc to be a counterclockwise direction as C-E, a positive code is added to the area of the circular arc area l2 since the circular arc l2 has the counterclockwise direction as C. Similarly, since a circular arc l5 has a clockwise direction as D, a negative sign is added to the area of the arc-area l5. Since a circular arc l8 has a counterclockwise direction, a positive code is added to the area of the circular arc area l8. By adding these results with each other, the area of the closed area including the circular arc area can be obtained.

Abstract: PURPOSE: To sufficiently secure a temperature margin of the circuit by providing plural FETs in which drain, gate and source electrodes are connected to prescribed terminals or nodes. CONSTITUTION: A gate electrode of an enhancement FET3 is connected to an output terminal 11 of a DCFL circuit, a drain electrode connects to a power supply terminal 100 and a source electrode connects to a node 21. Furthermore, a drain electrode of a depletion FET2 connects to the node 21, a gate electrode connects to a control terminal 12, and a source terminal connects to a power supply terminal 101. Then at a low level of an input potential, a drive FET1 of the DCFL circuit is turned off and the output potential rises up to a power supply voltage. Then a high potential in response to an output is kept to a potential of the node 21. At a high input level, the FET1 is turned on and its output is reduced, but since the FET3 is turned off, the potential at the node 21 is reduced. The potential at the node 21 is increased by setting the gate potential of the FET2 lower.

Abstract: PURPOSE:To perform the equimultiple detailed printing processing of printing data on a printer by taking in the printing data sent to a printing means from a host and outputting the same to the printing means while executing printing density converting processing, smoothing processing and data thinning processing. CONSTITUTION:When host printing dot data is sent to a printer 3 from a host unit, the host printing dot data is successively written in a host data memory means. When the next host printing data is sent out, a conversion means (a smoothing processing unit 27 serving as a conversion means and a smoothing means) reads the host printing dot data stored in an RAM 5 to convert the same to printing density and smoothes the host printing dot data while refers to the next host printing dot data.

Title: Optical information recording medium
Inventor: YAMAMOTO MASAKUNI
IPC: G11B7/24097
Filed: 1989-12-11
Abstract: PURPOSE:To increase a recording capacity by providing separating layers which vary in height from information tracks between the adjacent information tracks in a data region and setting the difference in the height at the value equal to the thickness of a recording layer or larger than this thickness. CONSTITUTION:Rugged bits, the separating parts 8, etc., are formed on the surface of a substrate 11 and a protective layer 12, the recording layer 13 and a protective layer 14 are successively formed thereon. The difference (h) in height between the information tracks 1 and the separating parts 8 is set equal to or larger than the thickness (d) of the recording layer 13. Heat diffuses according to the thermal conductivities of the respective layers when the the position of a point P is irradiated with the center of the spot of a light beam and the periphery thereof is locally heated. Since the thermal conductivity of the recording layer 13 is higher by >=1 digits than the thermal conductivity of the other layer, the heat transfers along the layer 13. Since the separating parts 8 are provided at this time, the heat is curvilinearly transferred in the transverse direction of the tracks and the effective heat transmission route increases. The width of the bits recorded by the heat is limited within the information tracks 1 and the track width is correspondingly reduced.
