Title: Photomask
Inventor: SHIGENIWA AKIYOSHI
IPC: G03F1/36
Filed: 1991-09-11
Abstract: PURPOSE:To lessen the deterioration of curved part and to allow the formation of high-accuracy patterns by lowering the transmittance of the branched or curved parts of light transmissive patterns. CONSTITUTION:The sizes of resist grooves in the corner parts increase if the L-shaped light transparent patterns 10 are exposed by using the positive type resist. The light intensity distribution calculated by simulation indicates that the light intensity in the corner parts is high. This phenomenon arises not only in the L-shaped corners but in the branch parts of the pattern shapes having T-shaped branched parts as well. The effective exposure is locally decreased by changing the transmittance of the branch parts and curved parts, by which the light intensity distribution in the branch parts and curved parts is equal to the same level as the level of the other parts and the deterioration of the patterns can be lessened. The change of the effective exposure can be made by sticking a material 9 which lowers the transmittance to the curved parts or disposing patterns below the resolution threshold thereto.

Title: Method for antilock control of car
Inventor: OKUBO TOMOMI
IPC: B60T8/66
Filed: 1989-09-08
Abstract: PURPOSE:To steadily control a car by interrupting the deceleration of a dummy car speed while the maximum wheel speed is below a threshold, and correcting the dummy car speed to keep its then value. CONSTITUTION:A threshold VT1 is set so that it may follow dummy car speed Vv decelerating at a decelerating grade of -1G with a fixed speed difference  V kept between them, and when the maximum wheel speed (four wheel select high speed) VwH of four wheel speeds becomes below the threshold VT1 at the time of t1, the deceleration of the dummy car speed Vv is interrupted from the time of t1 for correcting the dummy car speed to be kept constant. Thus, the threshold VT1 also can keep a constant speed lower as much as  V than the dummy car speed Vv from the time of t1. When the four wheel select high speed VwH exceeds the threshold VT1, the deceleration of the dummy can speed Vv having the deceleration grade of -1G is restarted from the time of 2t.

Moreover, when the actual white level jump rate is smaller, the reference voltage is increased by a predetermined value and the result is outputted. Then the operation above is repeated till the difference of the both or a ratio of the both reaches within a predetermined value. A reference voltage outputted from a microcomputer 29 is converted into an analog signal at a D/A converter 31. An AGC circuit 4 is subject to feedback control so that the reference voltage and the output of a detection circuit 7 are coincident.
