Title: Method for three-dimensionally expressing swinging object
Inventor: KATO HISAKAZU
IPC: G06T13/20
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To express a natural swinging motion by an object pattern by displaying the object of a swinging object so that a supporting point many not be deviated, changing a magnification ratio or a reduction ratio in a direction and three-dimensionally expressing the swinging object. SOLUTION: An object A of a fin fixes the location of a supporting point B and the reduction ratios of left and right sides are changed. Namely, (a) shows that the object A of the fin of a character ROM is displayed by fixing the location of the supporting point B at the reduction ratio of 100%, and (b) shows that the object A of the fin is displayed by fixing the location of the supporting point B at the reduction ratio of 50%. Further, (c) shows that the object A of the fin is displayed by fixing the location of the supporting point B at the reduction ratio of 25%. Because a more natural movement can be made by delaying the change of the reduction ratios at the time of the maximum and minimum, it is desirable that the reduction ratios are changed in a sine wave shape.

Title: Rotary driver
Inventor: SATO ICHIRO
IPC: F16H1/28
Filed: 1987-08-28
Abstract: PURPOSE:To make a rotary driver into such one that is less in friction resistance and energy loss in the inner part by constituting it with a sun gear fixed to an input gear, a planetary gear fewer in the number of teeth than this sun gear, an internal gear with which this planetary gear is engaged, another internal gear unitized with this internal gear, or the like. CONSTITUTION:Inputting into a crankshaft 1 is accelerated and transmitted from a sun gear 3 to a planetary gear 4 fewer in the number of teeth than the former, and furthermore rotation of this planetary gear 4 is transmitted to an internal gear 8. And the rotary driving force is transmitted from one more side internal gear to an external gear 12 to be engaged with the former, and furthermore it is transmitted to an output gear 18 by way of a small diametral internal gear 14, an external gear 16 to be engaged with this gear and a pinion 17 rotating solidly with this external gear. In a process of transmission of suchlike driving force, the output is doubled in speed to the input owing to a combination of gears. And, since tooth profile and space of each gear are circular in form, transmission of turning force among gears is smoothly performed as friction resistance becomes lessened and there is no loss in the force.

Filed: 1985-09-30
Abstract: PURPOSE:To stably restore to an original video signal by providing a switching means connected to either first or second output part and turned to the other one corresponding to the third timing pulse. CONSTITUTION:The signal whose inverse state is returned to its original state by a switch S4 is supplied to an output terminal 65 via a push-pull circuit constituted by transistors Q5 and Q6. When a switch S5 turns ON, a D.C. level of zero percent is reproduced by a capacitor 57 at the output terminal 65. The switch S5 is turned ON/OFF by a signal (g) from a synchronizing offset timing circuit 73 driven by a timing pulse P4. As a result, the synchronizing signal that has been offset is returned to its original level and an intact original video signal (c) can be obtained from the output terminal 65. In such a way, an accurate inversion reference level can be set for restoring the original video signal from the video signal transmitted by means of synchronizing-signal offset and video inversion.

IPC: B60T8/1755
Filed: 1996-08-14
Abstract: PROBLEM TO BE SOLVED: To generate a large braking force in a braking force control device to generate a large braking force corresponding to execution of emergency braking operation without generating a large-scaled over-steering condition in the case where the emergency braking operation is performed during turning. SOLUTION: Brake assist control(BA control) to generate braking liquid pressure having a large assist ratio compared to normal cases is executed when it is determined that emergency braking operation is executed by a driver. When BA control executing conditions are satisified (step 100), in the case where an absolute value of cross-acceleration Gy exceeds a specified value K (step 102), BA control to rear wheels is prohibited, but a large braking liquid pressure is supplied to front wheels only. In this case, reduction of cornering force of the rear wheels by execution of BA control is restrained, thereby over- steering tendency is restrained.

IPC: B21D26/027
Filed: 1992-08-12
Abstract: PURPOSE: To form a member into a desired contour, to improve strength properties and to reduce residual stress of the member by applying a computer simulation to a uniform visco-plastic modeling with an age forming process. CONSTITUTION: A desired metal member, having a complex shaped contour surface, is formed of an unformed member. The unformed member is overformed with a forming die, having a smaller curvature than the contour of the desired member. The unformed member is pressed into an overformed state. A thermal aging cycle is applied to the resultant member. The pressed member is cooled after the thermal aging cycle. Next, the geometrical representation of the member having the material properties of the desired metal member is simulated. Furthermore, the contour of small curvature is determined from a final process in order to make the desired metal member. Thus, the member is formed into the desired contour, and strength properties are simultaneously improved by heat treatment. As a result, a residual stress is improved and a suitable result is ensured, when the die is used for the first time.
