Title: Manufacture of semiconductor device
Inventor: SATO JUNICHI
IPC: H01L21/3065
Filed: 1985-07-11
Abstract: PURPOSE:To eliminate unetched step of a primary material by forming a coating layer on a workpiece to be treated in a structure which is thinned at a shoulder formed with the workpiece layer to be treated corresponding to the step of the primary material. CONSTITUTION:When a workpiece layer 3 to be treated is formed on a primary material 2 having a step 1, a shoulder 4 corresponding to the step 1 is formed at the layer 3 by reflecting the step 1 of the material 2. Then, a coating layer 5 is formed on the layer 3, and so formed as to be thinned at the shoulder 4 corresponding to the step 1. A resist pattern to obtain the desired pattern is formed on the layer 5, etched to first remove the layer 5 on the shoulder 4, i.e., the thinned film 5a to expose the layer 3 of the portion, and then etched in the desired pattern. At this time, all of the remaining coating layers are etched.

Title: Weld cladding roll having recess in corrugated shape
Inventor: KUROKI TAKANORI
IPC: C21D1/00
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To prevent generation of a crack in the circumferential direction for a long time and to hinder roughening in the top part of a bead by forming a smooth face in the top of a corrugated cladding layer of a weld cladding roll through machining and keeping the valley of the layer in the original weld surface. SOLUTION: On a roll base material 1, a cladding layer 2 is formed that is provided with a corrugated cladding layer 10 having four corrugations with a cladding thickness of t=4.5 to 6.5 mm. Then, only the top of the cladding layer 2 is finished by grinding to form a flat top part 3, making the diameter of the roll top to be 336 mm. The roll depth d from the top to the bottom is 1.5-2.0 mm, the width w of the flat top part 3 is 11-13 mm, and the width bw of the bottom is 12-14 mm. With this roll used as a guide roll, a crack is generated preferentially on the bottom between beads, showing slight expansion of the crack in the circumferential direction. As a result, a large effect is demonstrated in controlling the cracking direction, preventing the generation of a crack in the circumferential direction. (The numeric values are one embodiment).

Title: Color picture superimposing device
Inventor: YOSHII SEIICHIRO
IPC: H04N5/278
Filed: 1989-06-13
Abstract: PURPOSE:To attain simultaneous display of eight colors by outputting luminance information of a designated color for each picture element based on red, green and blue luminance information for each picture element and a color control signal designating a color for each inputted picture element externally. CONSTITUTION:A luminance information storage means 5 stores binarized red, green and blue luminance signals for each picture element as to one picture in the scanning order for each color respectively. Then a luminance information output means reads the luminance information stored in the luminance information storage means 5 for each color in the order of scanning and outputs the information to a luminance information synthesis means 307. The luminance information synthesis means 307 outputs the luminance information as to the designated color for each picture element based on the red, green and blue luminance information for each picture element outputted from the luminance information output means and a color control signal designating the color for each externally inputted picture element. Thus, simultaneous display of eight colors is attained.

Title: Bearing device
Inventor: NISHIHARA YOSHIMI
IPC: F16C19/16
Filed: 1979-11-22
Abstract: PURPOSE: To enhance the durability of a bearing device, by equally lubricating a pair of juxtaposed angular ball bearings.  
     CONSTITUTION: The inner races 16 of bearing units 12, 13 are each divided into two portions. The shoulder portion 16a, which has an unloaded surface 39, is made separate from the other portion 16b of the race 16. The area of an opening 40 defined by the shoulder portion 16a and the outer lace 20 is equalized to that of an opening 41 defined by the other portion 16b and the outer race 20. Since the openings 40, 41 opposed to injection nozzles 30 in angular ball bearings 14, 15 have the same area, the quantities of lubricating oil D injected into the bearings 14, 15 through a high-pressure oil supply passage 25 and the injection nozzles 30 are equal to each other. This results in equalizing the degrees of wear of the bearings 14, 15 to each other and enhancing the durability of the bearing units 12, 13.

Filed: 1986-06-30
Abstract: PURPOSE:To effectively cool an electric motor and a pump by forming a space between the pump with which a revolution shaft is connected and the electric motor and forming a hole for the communication between the space and the inside of the electric motor and allowing a fan fixed onto the electric motor shaft to revolve in the space. CONSTITUTION:The revolution shaft 6 of a pump 1 is connected with the shaft 7 of an electric motor 2 through the space 5 formed by the bracket 3 of the electric motor 2 and the side plate 4 of the pump 1. Further, a hole 9 for the communication between the space 5 and the inside of the electric motor 2 is formed onto the bracket 3. When the electric motor 2 revolves, a fan 8 installed onto the shaft 6 stirs the air in the space 5, and said air flows into the inside of the electric motor 2 through the communication hole 9. Therefore, the air circulates inside the electric motor 2 and the inside the space 5, and cools the electric motor 2 and the pump 1. Therefore, the inflow of air from outside is prevented, and transport of foreign materials into the cooling air is prevented, and effective cooling is permitted.
