Title: Preparation of semiconductor device
Inventor: TOKUNAGA HIROSHI
IPC: H01L23/52
Filed: 1979-12-06
Abstract: PURPOSE:To form more microscopic electrodes and wiring on a semiconductor substrate by patterning a nitride film of a metal having a high melting point, then reducing a part of periphery of the patterned film to remove and reducing the remaining nitride film again. CONSTITUTION:In the process to form a gate electrode 2G of an MISFET semiconductor device 1, on a gate insulating film 2 an Mo2N film 3 and an Si4N4 film 4 are provided and patterned. The periphery 3RED of the patterned Mo2N film is reduced into an Mo layer. After the Si4N4 film 4 and the peripheral reduced Mo layer 3RED are removed, the remaining Mo2N film 3 is reduced again to form an Mo gate electrode 3G. Said procedure permits more microscopic electrodes and wiring to be formed beyond the micrifiable limit of patterning.

Title: Preload measuring apparatus for gear engaging unit
Inventor: ISHIDA FUKUYOSHI
IPC: G01L5/00
Filed: 1989-06-21
Abstract: PURPOSE:To make it possible to measure the single preload on a shaft on which a gear is mounted under the state wherein the gear is engaged with another gear by obtaining a rotary torque value which is measured with a torque sensor for one shaft when driving motion and driven motion are reversed. CONSTITUTION:At first, a transmission 10 is set at a neutral state. Therefore, a shaft P and a shaft S are not in linked moving state and can be rotated independently. The shaft S and a shaft D are associatively moved through gears SG and DG. Under this state, the shaft S is rotated and driven at a specified number of rotation with a motor SM for the shaft S. At this time a clutch SC is connected, and a clutch DC is disconnected. The gear SG and the gear DG are in the engaged state, and the shaft D is also rotated and driven with the motor SM for the shaft S. After the rotation and the driving of the shaft S by the motor SM for the shaft S are stabilized, the rotation of a motor DM for the shaft D is started. The clutch DC of the shaft D is connected at the same time, and the number of rotation is delicately increased. The circumferential speed of the gear DG on the shaft D is made faster than the circumferential speed of the gear SG on the shaft S. As a result, the curve of the rotary torque of values of the shaft S is obtained from a torque sensor SS for the shaft S.

Title: Method for partially aquiring and defining spline curve
Inventor: SEKI MAKI
IPC: G05B19/4097
Filed: 1989-06-23
Abstract: PURPOSE:To make a new spline curve same as the correspondent part of an original spline curve, from which the sequence of points is aquired by calculating the tangential vector of the original spline curve with automatic programming by inputting the code of the original spline curve to be used and starting and ending points to use the sequence of the points in the original spline curve. CONSTITUTION:When the code of the already defined spline curve and the starting and ending points to be used from the sequence of the points in the said spline curve are inputted, an automatic programming device calculates the tangential vector in the inputted starting and ending points according to a method for calculating the tangential vector. Then, the new spline curve is defined by these respective calculated tangential vectors and the designated starting and ending points in the original spline curve. Thus, the new spline curve is overlapped with the correspondent block of the original spline curve and made same as the original spline curve.

Abstract: PROBLEM TO BE SOLVED: To protect a solar cell cover from traffic, prevent a lowering of light- collecting power and prolong the life of a solar cell type luminous road rivet by attaching a partition frame having a high rigidity inside the case of the solar cell type luminous road rivet. SOLUTION: A partition frame 31 for protecting a solar cell type cover 41 is installed inside a case 21 of a solar cell type luminous road rivet to be installed on the surface of a road. A partition frame 31 is formed of an outer frame at an outer peripheral portion in contact with the inner periphery of the case 21 and a grid-shaped partition separating the inside of the outer frame and is produced of a raw material having a high rigidity such as aluminum cast iron. A partition frame 31 attached to the inside of the case 21 prohibits the contact of traffic on the road to the solar cell cover 41, thereby the surface of the solar cell cover 41 is prevented from being scratched resulting in a drop in the light-collecting power and the life of the solar cell type luminous road rivet is prolonged. Also, since the strength of the solar cell cover 41 can be reduced, the thickness of the solar cell cover 41 can be reduced or its shape can be changed so that the light collecting effect can be improved.
