Title: Method for forming conductive plug in contact hole
Inventor: KA ZAIKI
IPC: H01L21/3213
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To decrease cavity part by forming a conductive plug on a glue layer in a contact hole and etching the glue layer on the surface of an insulator using a mixed gas of a gas etching the glue layer and a gas forming residues on the insulator. SOLUTION: An interlayer insulator 12 is deposited on the entire surface of a substrate 11 and a contact hole 12a is made at a specified part of the interlayer insulator 12. A glue layer 13 is formed in the contact hole 12a and on the surface of the interlayer insulator 12. Subsequently, a tungsten layer 14 is formed on the glue layer 13 and a tungsten plug 14a is formed in the contact hole 12a. Thereafter, the glue layer 13 is etched off from the surface of the interlayer insulator 12 using a mixed gas of Cl2 /BCI3 . In this regard, CL2 gas etches the glue layer 13 while BCl3 forms residues on the side wall of the contact hole 12a and the residues prevent over etching of the glue layer 13 on the side wall of the contact hole 12a.

Filed: 1979-12-26
Abstract: PURPOSE:To connect both electrodes on a semiconductor element and on an accommodating vessel by a method wherein an insulating plate being buried in vertically with fine conductors is placed between the both electrodes. CONSTITUTION:The golden fine wires 7 of about 50mum are buried vertically in a heat-resisting plastic plate of about 100mum thickness to constitute the insulating plate 6, and the golden fine wires are exposed on the both faces of plate to the length nearly equal with the diameter of the wire. The golden fine wires 7 coming in contact with the respective electrodes 2, 4 of the semiconductor element 1 and the vessel 3 are connected by thermal adhesion with pressure. When the thermal adhesion with pressure is to be performed, positioning of the element and the vessel is performed placing the insulating plate 6 between them, it is heated from the upside of a cap on the back face of the element, and is heated at about 400 deg.C in a reductive or a neutral atmospheric current. By this constitution, the number of process is broadly reduced, and the formation of bump electrode becomes unnecessary. When the insulating plate 6 is formed with alpha-rays preventing material, the generation of soft errors can be prevented.

IPC: G09G5/26
Filed: 1987-07-08
Abstract: PURPOSE: To make it easy to read a character or word by adding a character size varying circuit, and increasing and decreasing character size within a range between maximum size and minimum size irrelevantly to the enlargement/ reduction rate of pattern information. CONSTITUTION: Display information consisting of character information including pattern information and character size setting information inputted from a processor such as a computer 1 is separated by a display control circuit 2 into the character information and pattern information, and the character size setting information included in the character information is supplied to a character size varying circuit 10. Therefore, the display size of the character can be held within the specific range at any time irrelevantly to the enlargement or reduction rate of other pattern information. Consequently, the character is neither enlarged or reduced unnecessarily to prevent the character or word from being unreadable.

Title: Insole of shoes
Inventor: TAKEHANA YOSHIKI
IPC: A43B17/03
Filed: 1994-07-22
Abstract: PURPOSE:To provide an insole of shoes having an improved unsweating effect, a satisfactory feel of wearing and cushion property by projecting upward the upper surface of the heel part to form a recessed part on the lower surface of the heel part. CONSTITUTION:An insole 4 of shoes is composed of an overlapped body of a cloth and foamed body for example, and the heel part 5 is formed on the lower surface with a recessed part 6 by projecting the upper surface of the heel part 5 upward convexly. Thus, the volume of the recessed part 6 in the heel part 5 can be increased without thickening the insole 4. Thus, the insole 4 ensures sufficiently the volume of the recessed part 6 in the heel part 5 to improve the exhausting effect for preventing the inside of shoes from becoming sweaty while a satisfactory feel of wearing and cushion property are given without thickening the insole. Also, since the upper surface of the heel part 5 is projected upward convxly, a pressing effect on the recessed part 6 by the heel is increased to further improve the exhausting effect.

Title: Image forming device
Inventor: MORO AKIHIRO
IPC: G03G21/00
Filed: 1992-06-29
Abstract: PURPOSE:To copy two sheets of originals on one sheet by forming a reduction image for the two sheets of originals on a medium to be image-formed when the size of the reduction image of the original is less than 1/2 of the medium to be image-formed. CONSTITUTION:When it is informed that the size of the original is, for example, less than A4 from an original size 'detecting part 65, a main control part 61 drives an original scanning part driving part 68, and an original scanning part processing part 69 outputs the reduction image obtained at a charge conversion part 11 to an image processing part 66. The image processing part 66 performs processing such as shading correction, etc., on an image signal from the original scanning part processing part 69, and stores it in an image memory part 67. When the size of a second original is less than A4, the main control part 61 synthesizes it with the image of a first original stored in the image memory part 67, and outputs a synthesized image to an image formation part processing part 71. Thereby, the image formation part processing part 71 prints the synthesized image of two sheets of originals supplied from the image processing part 66 on one sheet.

CONSTITUTION:A data Pi of a position and a data PiT being attendant on this position are stored in a single data area 37, and from this single data area 37, the data PiT being attendant on the position is retrieved together with the data Pi of the position. Therefore, no variable is required, and it is unnecessary to execute a management, etc. for allowing the data of the position and the variable to correspond with each other. Also, by executing a reference and a registration of a data being attendant on the position in a processing program of a moving control of a robot, the processing of the moving control can be changed by registering the data.

Title: Carry propagating circuit
Inventor: YAMAUCHI TATSUMI
IPC: G06F7/506
Filed: 1985-08-05
Abstract: PURPOSE:To form a carry propagating circuit which is operated at a higher speed, by changing an MOS size of a transfer MOS transistor and a discharge MOS transistor, at every bit. CONSTITUTION:An MOS size of a transistor is changed at every bit. For instance, when the MOS size of MOSs 9, 8, 7, 6 and 10 in a path 1 is changed to W, a size of a MOS 11, a size of a MOS 12, a size of a MOS 13, and a size of a MOS 14 become W/2, W/3, W/4 and W/5, respectively. In such a way, the junction capacitance of nodes 26, 27, 28 and 29 decreases by about 1/2% as a whole, and by that portion, the highest operating speed in the path 1 is increased.

Title: Vane type compressor
Inventor: NAKAJIMA NOBUFUMI
IPC: F04C18/344
Filed: 1985-08-05
Abstract: PURPOSE:To obtain a variable capacity type compressor of simple structure, by conducting vane back pressure into the pressure receiving chamber of a piston valve opening and closing a bypass port, and communicating the pressure receiving chamber to a suction chamber via a closing valve. CONSTITUTION:In case that gas pressure of a suction chamber 20 is below a prescribed value, a ball valve 29 opens so that pressure of a vane back pressure chamber 18 drops down toward the gas pressure of the suction chamber 20. When pressure of back pressure receiving chamber 82 communicated with the vane back pressure chamber 18 becomes below spring power of a coil spring 83, slider 81 is energized by the coil spring 83 to move down toward a rotor axis 12 so that a bypass port 21 is opened. Thereby, gas which is being compressed in a cam ring 8 is relieved from the bypass port 21 into the suction chamber 20, so that compressing capacity of a vane compressor can be reduced.
