Title: Simulation apparatus and simulation method
Inventor: IMANAGA TOSHIHARU
IPC: H01L21/336
Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To calculate and display updated electrical characteristics of a device based on the updated graphic display by transferring the updated figure obtained by revising the figure on the display with a drawing means to a device simulator as the new impurity concentration via a distribution data input means. SOLUTION: Structure and fabrication condition of a device are inputted to a process simulator 2 and the structure and impurity concentration distribution of the device are displayed 4 as the figure via an image drawing means 5. Simultaneously, impurity concentration distribution is transferred to a device simulator 3 from a process simulator 2 for image display 4 of the electrical characteristics of the device calculated. When this display contents are expected characteristics, simulation is terminated. If such contents are different from the expected one or if it is requested to know the electrical characteristic when the impurity concentration distribution or device structure are revised tentatively, the desired revision is made to the display of the device structure and impurity concentration distribution using a image drawing means 5.  A distribution data input means 6 reads a new display image and displays image to the simulator 3.

Title: Wheel with modification enveloping surface for hourglass-shaped worm
Inventor: ARITA MITSUO
IPC: F16H55/08
Filed: 1980-12-22
Abstract: PURPOSE: To obtain a wheel for a hourglass-shaped worm that will be in gear with the hourglass-shaped worm, wherein the depth of the enveloping surface of each of the gear teeth thereof is modified to have a rather shallow depth so that when they are assembled, even if there exists displacement, extremely biased abutting of the tooth surfaces is prevented.  
     CONSTITUTION: The wheel 16 that will be meshed with the hourglass worm 14 has an enveloping surface 20 on the tooth surface of each tooth 18. In this wheel 16, compared with the prior enveloping surface 20, the enveloping surface 52 of each tooth 18 has a width W the same as the prior art, and a depth D that is modified to become rather shallower than the depth D' of the enveloping surface 20. Thus, when the hourglass-shaped worm 14 is assembled with it biased by ΔZ in a direction of Z (direction of width of the teeth of the wheel 16), extremely biased abutting can be prevented. Therefore, the adjustment of assembling in the direction of the width of the teeth of the wheel 16 can be performed quite easily.
