Title: Manufacture of metallic pipe having groove in inner surface
Inventor: TATSUMI ARITAKA
IPC: B21C1/22
Filed: 1982-04-14
Abstract: PURPOSE:To form grooves in the inner surface of a pipe, in which each groove has a wide space at the side of inner circumferential surface of the pipe and a narrow opening at the side of pipe center, by deforming a part of the axial center side of each projecting part which demarcating the groove toward the outer peripheral side after forming the grooves, of which respective groove-demarcating opposing walls form >=0 deg. angle to each other, in the inner surface of the pipe. CONSTITUTION:A metallic pipe 1 to be processed is moved in its axial direction A, and is radially reduced by a grooved plug 2 positioned in the pipe 1 and the 1st reducing means 4 which presses the pipe wall 3 from the outer-peripheral side of the pipe 1 to the side of the plug 2 to perform the 1st processing of the inner surface groove. Next, the 2nd processing of the inner surface groove is performed by a plug 5, which has pins and is positioned in the pipe 1, and the 2nd reducing means in the same manner to form a body having prescribed grooves in its inner surface. The plug 2 has projections 2a extending in its axial drections, and the angle alpha formed between the opposing surfaces of respective projections in made to alpha >=0 deg.. On the other hand, the plug 5 has e.g. cylindrical pins 6 to form a body having grooves with prescribed cross sectional shapes, in relation to the grooves 7 formed by the plug 2. Thus the prescribed grooves 12 are formed by positioning the pins 6 to the grooves 7 at the time of reducing the pipe.

IPC: H03K3/02
Filed: 1981-04-24
Abstract: PURPOSE:To provide a time correcting means having a high durablility, and an input means for information, by detecting a mechanical displacement of an operating member as a change in capacity. CONSTITUTION:A correction speed adjusting switch 51 is screwed in a case 52 by a bolt-shaped piston 61 for mounting.

Title: Sealed oil feeder for dynamo-electric machine
Inventor: ASAKURA AKIRA
IPC: H02K9/08
Filed: 1991-03-04
Abstract: PURPOSE:To adopt a prevention measure against the development into powerful cavitation by opening an automatic valve with a controller when it detects the vibration by small and weak cavitation, and further opening a hydraulic adjusting valve, too, which returns the oil sealed in the discharge pipe and a bypass pipe to a vacuum oil tank. CONSTITUTION:In case that cavitation occurs, the vibration in a sealed oil pump discharge pipe 12 is furthered by the disturbance of the oil flow inside the pipe and the vibration value increases. Accordingly, by monitoring the condition of this vibration with an acceleration sensor 19 at all times, it detects the specified small and weak abnormal value by vibration increase at cavitation occurrence and issues an alarm, and at the same time it opens an automatic valve 17 with the operation signal through an amplifier 20 and a controller 21. And by returning some of the discharge of the sealed oil pump to the suction side through a bypass pipe 16, the pressure of the suction side of the sealed oil pump is raised, thus it can prevent the cavitation from developing into powerful one.

Title: Wiring formation method
Inventor: SUMI HIROBUMI
IPC: H01L21/3205
Filed: 1989-03-15
Abstract: PURPOSE:To grow, without hindrance, conductive material even at a part which is arranged at the bottom of an aperture and turned into barrier metal by a method wherein, after a film containing an element turning to the barrier metal at the bottom of the aperture is formed, and conductive material is buried in the aperture, the film containing the element turning to the barrier metal is alloyed. CONSTITUTION:At the bottom of an aperture 4 where a semiconductor region 2 formed on an insulating film 3 or the surface of a wiring layer is exposed, a layer 6 containing an element turning to barrier metal is formed; conductive material 7 is burried in the aperture 4; a wiring layer 9 is formed. This wiring formation method contains a process alloying the layer containing the above element turning to the barrier metal. For example, a thin tungsten film 5 is formed on the bottom surface of the contact hole 4, and nitrogen is implanted; thereby the tungsten film 5 is changed into an amorphous-like film 6 composed of tungsten and nitrogen. After the contact hole 4 is filled with a tungsten film 7 formed by selective CVD, heat treatment is performed at about 800 deg.C. Thereby the mixed film 6 is alloyed, and turned into a WN film 8.

Title: Burner
Inventor: KURAMOTO KAZUO
IPC: F23D14/02
Filed: 1988-03-15
Abstract: PURPOSE:To facilitate maintenance work as well as prevent the generation of going out, by ejecting mixed gas circulating by way of a gas passage, and burning said mixed gas. CONSTITUTION:Mixed gas supplied from a supply nozzle 11 of a burner device 1 is converted from dynamic pressure to static pressure in a windbox 12 and is supplied to a swirler member 15 by way of a communication hole 13. The mixed gas is supplied into a space in the radial direction of a plurality of swirler impellers marked with Arrow A1. From this space is discharged the mixed gas in the radial direction marked with Arrow A2 through each impeller 16. Since the mixed gas flows along the configuration of the curved swirler impellers 16, it is swirled further to rise and continuously swirl, moving through a second gas passage 29. Then, the mixed gas is ignited by source fire by a pilot burner 31 or the like installed to a fitting hole 30 and the flames are generated, and discharged upward from the upper part of the second gas passage 29. It is, therefore, possible to produce a favorable mixed status between air and gas and to realize high efficient combustion.

Title: Head cleaner
Inventor: KOBAYASHI AKIHIRO
IPC: G11B5/41
Filed: 1995-03-22
Abstract: PURPOSE: To prevent sticking of dusts, magnetic powders, etc., to a magnetic head and to improve a cleaning effect without destroying the magnetic head. CONSTITUTION: A head cleaner 10 performs cleaning in contact with a magnetic head 4 rotating together with a rotary drum 5. After completing cleaning, the head cleaner 10 moves away from the magnetic head 4 because of driving of a plunger 8 and produces a wind force by means of a circuit substrate 21 formed like an impeller in the rotary drum 5. This wind force is blown out of the punched hole 14 of a fixed drum 1 and received by an impeller member 13, thereby rotating the head cleaner 10 and a shaft 11 together with the impeller member 13. Then, since the head cleaner 10 is rotated, this rotation shakes off stuck dusts, magnetic powders, etc. Further, the cam groove 17 of the shaft 11, a ball, etc., cause the level of the shaft 11 to simultaneously change, changing the contact position of the head cleaner 10.

IPC: B41J2/21
Filed: 1983-04-11
Abstract: PURPOSE:To elevate the quantity of color recording such as black or the like, by making the dot diameter in recording dot on paper with No.1 and No.2 dot recording elements be the same as the dot diameter with No.3 dot element. CONSTITUTION:For example, the ink of cyan, magenta and yellow are fed to No.1 to No.3 color recording nozzles 1-3 and recording is carried out by discharging liquid drops by the drive of piezoelectric element or the like. At that time, the nozzles 1-3 on carriage 5 are, in a horizontal straight line state, arranged. Then, in recording special color, for example, printing in black color, it is generated by making the liquid drops discharged from nozzles 1-3, while being mixed, reach the same point and the black dot B1 is formed. Further, the black dot B2 is formed from black color nozzle 4. Therefore, the black color recording time by nozzle 4 only can be reduced by half and the recording speed can be raised 2 times. Because the dot B1 is formed by mixing 3 colors, its dot diameter becomes larger than that of dot B2. Therefore, by making the diameter of nozzle 4 larger than those of nozzles 1-3, the diameters of dots B1 and B2 are equalized.
