Title: Manufacture of semiconductor device
Inventor: OOZEKI NOBORU
IPC: H01L21/3205
Filed: 1984-07-06
Abstract: PURPOSE:To avoid the disconnection of an upper layer wiring formed onto a lower layer wiring by previously changing 1/3-2/3 of the thickness of the Al lower layer wiring into Al2O3 first when shaping multilayer wirings and shaving off Al2O3 intruding to the end section of the lower layer wiring remaining under a mask when the multilayer wirings are etched selectively by using the mask. CONSTITUTION:An insulating film 2 for insulating isolation is applied onto the surface of a semiconductor substrate 1, an Al thin-film layer 3 as a lower layer wiring is formed onto the insulating film 2, and a mask material 6, which has large adhesive properties with the layer 3 and consists of a negative type resist according to a predetermined pattern, is shaped onto the layer 3. The substrate 1 is anodized in a 2% sulfuric acid aqueous solution to convert only 1/3-2/3 of the film thickness of the layer 3 into an Al2O3 layer 7. Consequently, the layer 7 is intruded even to the end section of the layer 3 remaining under the mask material 6, and the layer 7 and the exposed layer 3 are removed by a liquid having the large etching selection ratio of Al2O3/Al. An upper wiring layer 5 is applied onto the lower wiring layer 3, the end section thereof is made gentle, through an inter-layer insulating film 4.

Abstract: PURPOSE: To eliminate the possibility of causing damage or defect in a conductive layer by forming residues of spacers at opening side walls so as to reduce the abruptness of curved parts between contact regions and spacer residues. CONSTITUTION: A first material layer 4 is formed on a cover layer 3. A second material layer 5 is fomred on the layer 4. The layers 4, 5 are anisotropically etched at different rates so that the layer 4 is etched more slowly than the layer 5 in an anisotropical etching step. After this etching to expose the surface 3a of the layer 3 and surface region at a conductive level 1, the side walls 2a of openings 2 remain covered with a material 40. Other material parts 50 extend on the material 40 above the side walls of 2a of the openings 2 from the exposed region 10 at smaller distances that the depth of the opening 2. Thus it is possible to provide a conductive layer 6 on a surface having comparatively gentle slopes and corner and to prevent the damage and defect from occurring.

Abstract: PURPOSE:To feed large current to a circuit on a printed wiring board safely and certainly by fastening by screw a U-form metal piece which pinches sandwichedly a current feeding terminal block soldered fast to a wiring pattern on the wiring board. CONSTITUTION:A current feeding terminal block 18 is mounted by solder on a wiring pattern of a printed wiring board 2.

Title: Flow rate control valve
Inventor: TANAKA YASUO
IPC: F16K3/32
Filed: 1979-11-01
Abstract: PURPOSE: To decrease an outflow angle as the spool displacement increases in a small range of the spool displacement and prevent a change of flow rate even for a change of load pressure in a large range of the load pressure.  
     CONSTITUTION: In this flow rate control valve, when displacement (x) of a spool 3 is small, flows (m), (n) affected by wall faces 11a, 12a of internal grooves 11, 12 are more dominant than a flow l along a sloped groove 10 with an outflow angle ϕ larger than an angle α of the sloped groove 10. When the spool displacement (x) increases to not less than a prescribed value, the effect of the flows (m), (n) is eliminated to equalize the outflow angle ϕ to the angle α. While the relation between the spool displacement (x) and an opening area (a), because the internal grooves 11, 12 are provided, is such that a curve of the opening area (a) for the spool displacement (x) is convex to the above in a small range of the spool displacement (x). In this way, an excessive decrease of the spool displacement due to the flow force can be pevented thus the flow rate in a large range of load pressure can be maintained at constant.

Abstract: PROBLEM TO BE SOLVED: To allow an easy jointing work by jointing a square steel pipe to a beam steel frame, inserting a concrete-filled steel pipe column in the square steel pipe, and filling a gap between the square steel pipe and the concrete-filled steel pipe column with mortar. SOLUTION: A joint element 21 formed out of joint steel frames 22 welded to both outer surfaces of a square steel pipe 20 is laid as a beam joint part on the upper end of a lower concrete-filled steel pipe column 11. Then, the upper end of a steel pipe 12 used for the lower concrete-filled steel pipe column 11 is inserted in the lower half part of the square steel pipe 20. Subsequently, the lower end of a steel pipe 12 for the concrete-filled steel pipe column 11 is inserted in the upper half part of the square steel pipe 20, thereby abutting the upper and lower steel pipes 12 to each other. Then, the steel pipes 12 are filled with concrete 13, and mortar is fed to and cured in a gap between the steel pipes 12 for the concrete-filled steel pipe columns 11 and the square steel pipe 20.  Thereafter, a beam steel frame 23 is welded and jointed to the jointing steel frames 22 of the joint element 21, thereby completing a joint between the column 11 of circular cross section and the beam steel frame 23.

Title: Ink jet head and manufacture thereof
Inventor: MIZUNO TSUNEO
IPC: B41J2/15
Filed: 1986-06-17
Abstract: PURPOSE:To prevent the influence on ink jet operation due to the standing ink oozing from a nozzle, by a method wherein nozzle lines are separated and the lower part of the nozzle lines is made plane by establishing the groove part separating a nozzle fact at a position other than the lower part of plural nozzle lines. CONSTITUTION:In an ink jet head, nozzle lines 2a, 2b are separated by a groove part 2c on a nozzle face 2 and its lower part is not separated and constructed as a plane 2d. For instance, nozzle line plates 3, 5 are vertically joined by pressure pinching a spacer 4 between them. Thereafter, the nozzle face 2 having the groove part 2c due to a window part 40 is made to be obtained by working it by cutting or grinding so that the window part 40 of the spacer 4 may be exposed. Therefore, the thickness of the ink layer on a nozzle can be thinned and the influence on the ink jet operation of the nozzle due to oozing ink can be prevented. Besides, the effect that the title ink head can be realized without making the head large, is obtained.

Title: Automatic operation control unit for unmanned car
Inventor: HIROSE NORIAKI
IPC: B65G43/00
Filed: 1979-10-31
Abstract: PURPOSE: To prevent an unmanned car from colliding against a shutter by sending a commnad to run after detecting the open state of the shutter unit.  
     CONSTITUTION: When a detector F detects arrival of an unmanned car D at a temporary stop zone, a commnad to open is given to a shutter unit C. With the shutter C in an open state, a contactless switch LS3 is closed and a shutter open detection relay RY9 is excited. Consequently, a relay RY10 for running command operates to give a command to run to the unmanned car D. Accordingly, the unmanned car D runs toward the fixed stop zone G through the shutter C. If, while the car is running, by some reason the shutter C becomes a closed state, the switch LS3 becomes open, and the relay RY9 becomes nonexciting. Accordingly, the relay RY10 also becomes nonexciting and the unmanned car D stops. In this way, collision against the shutter C can be prevented.
