Patent JP-H04266026-A (JP)
Title: Manufacture of semiconductor device
Inventor: SHINOHARA KEIJI
IPC: H01L21/768
Filed: 1991-02-20
Abstract: PURPOSE:To provide contact holes with no metal crown by opening contact holes in an insulating film on a metallic base film, and flattening the insulating film. CONSTITUTION:An insulating film 12 is formed on a semiconductor substrate 11 on which components are formed. The insulating film 12 consists of two areas different in level. Aluminum wiring patterns 13A and 13B are formed on the higher and lower areas of the insulating film 12, respectively. An SiN film is deposited over the substrate to cover the aluminum wiring patterns 13A and 13B. Contact holes 16A and 16B, reaching the wiring patterns, are simultaneously opened using a resist mask 15. After resist is applied over the surface, the SiN film 14 is flattened by etching back under the conditions in which the resist and SiN film 14 have the same etch rate. As a result, contact holes with no metal crown are realized.

Title: Method for drawing metallic pipe
Inventor: YOKOYAMA TETSUO
IPC: B21C3/12
Filed: 1988-02-05
Abstract: PURPOSE:To improve the straightness and quality of product by setting the inclination angle of a die and the height of its central position respectively to specified values and then drawing a pipe. CONSTITUTION:The axis of a cold drawing die 3 is set so that the axis looks upwards by a specified inclination angle theta to its drawing line (m). The inclination angle theta is obtained and set experimentally in advance based on a necessary drawing force. Further, the central position of the hole of the die 3 is raised in advance by delta, the quantity of drop due to the slouch of the stand when the drawing force acts. When the drawing force is added by a gripper 4 to a base pipe 1 the die 3 becomes vertical and the central position of the die hole keeps a regular state. In this way, a satisfactory straightness is given to the drawn pipe and defects such as a guide mark, etc., are prevented from occurring. As a result, the straightness and quality of the product are improved.

Title: Reflection preventing film of plastic optical member
Inventor: MAEZAWA HIDENORI
IPC: G02B1/115
Filed: 1981-02-25
Abstract: PURPOSE:To produce with high workability a reflection preventing film having high light transmittance and high strength, by first vapor-depositing ZrO2 and then SiO with oxidizing on a plastic optical member. CONSTITUTION:A reflection preventing film 1 is formed on a plastic optical member 2 of PMMA, etc. by first vapor-depositing a ZrO2 layer 3 with 1/2lambda- 1/8lambda thickness (normally 1/4lambda) and then the 2nd layer 4 with 1/4lambda thickness along with oxidization of SiO. The layer 4 contains not only SiO2 but nonoxidized SiO, SiO3 which is not perfectly oxidized, etc. Owing to this layer, the equal to or higher strength than a conventional film which is obtained through a surface reinforcement process is secured for this new reflection preventing film.

Title: Container conveying device
Inventor: HASHIMOTO NORIAKI
IPC: B65G47/22
Filed: 1986-02-07
Abstract: PURPOSE:To convey containers always in a stable condition, by providing an attitude changing device for setting the container in its conveying attitude in association with the detection by an attitude sensor indicating that the attitude of the container is not for conveyance. CONSTITUTION:An attitude sensor 3 arranged at the terminal end of a horizontal conveyer 5 detects whether a container 1 is in its conveying attitude or not, and if it is in the conveying attitude, the container 1 is fed through an attitude changing device 4 onto a conveyer 2 for conveyance. When the sensor 3 detects that the attitude is not for conveyance, the detector issues an instruction to the attitude changing device 4 which therefore rotates when the container 1 is fed thereinto. Thereby the attitude of the container 1 is changed within the device 4 and is fed onto the conveyer 2 for conveyance.

Title: Base and magnetic recording medium formed by using the same
Inventor: MATSUMURA SHINICHI
IPC: G11B5/73
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To obtain a base with which the distortion by tensile force and the elongation by a change in an environmental temp. hardly arise by limiting the range of the Young's modulus and coefft. of thermal expansion in a longitudinal direction. SOLUTION: The Young's modulus in the longitudinal direction of the base is regulated to >=600kg/mm<2> and the coefft. of thermal expansion to >=0/ deg.C. If the Young's modulus in the longitudinal direction of the base is regulated to >=600kg/m<2> in such a manner, the distortion of the magnetic recording medium is suppressed to a lower level in spite of the instantaneous generation of the tensile strength in the longitudinal direction by a sudden start or sudden stop. If the coefft. of thermal expansion is regulated to 0 deg./ deg.C, the elongation of the magnetic recording medium is suppressed to a lower level in spite of the change in the environment temp. from the high temp. to the low temp. Then, a good traveling property is obtd. with the magnetic recording medium formed by using such base. In addition, the magnetic recording medium is taken up with a good style on the reel of a cartridge. The flawing of the medium by contact of its end with the collar part of a guide roll is suppressed.

IPC: G06F9/40
Filed: 1991-02-21
Abstract: PURPOSE:To prevent the runaway of a program caused by execution of a transfer control instruction which calls the subroutine included in an unlinked compiling unit. CONSTITUTION:An instruction 4 transfers 'program counter value + byte number of instruction 3 + byte number of instruction 5' to a stack (steps 1 and 5). An instruction 3 shifts the control to a subroutine if a relative address is not identical with O (step 2). An instruction included in the subroutine transfers the value to a program counter from a stack and shifts the control to the instruction (step 4) following an instruction 5 (step 3). The instruction 3 shifts the control to the instruction 5 if the relative address is identical with O (step 6). Then the instruction 5 transfers the value to the program counter from a stack and shifts the control to the next instruction (step 8) in a step 7 respectively.

Abstract: PURPOSE:To achieve the optimal focus over the entire screen by making the converging angle of electron beam in vertical direction smaller than in horizontal direction thereby forming the material point in vertical direction further than that in horizontal direction under the material point forming area. CONSTITUTION:Because of oval opening (DV<DH) at the endface of grid G3 in an electron gun 11, the vertical converging angle thetaV will become smaller than the horizontal converging angle thetaH thereby the vertical f-value fV will become longer than the horizontal f-value fH. Upon deflection of the electron beam through convergence, free deflection fields, an optimally focused beam spot having low harrow at the corner section is obtained. While since laterally elongated beam through-holes 17R-17B are made through the grid G1, the vertical material point having longer f-value will move further than the horizontal material point having short f-value under material point forming are to bring the electron beam into the optimal focus condition both in the horizontal and vertical directions in the center of screen resulting in a circular beam spot.
