Title: Film-shaped coil and manufacture thereof
Inventor: SUZUKI TATSUHIRO
IPC: H01F17/00
Filed: 1980-01-07
Abstract: PURPOSE:To extend the range for forming an inductance as a solenoid having a magnetic core by printing and baking a lower conductor layer on an insulating substrate and printing and baking an upper conductor layer thereon while connecting both ends of the lower conductor layer through a magnetic member to one another. CONSTITUTION:The lower conductor layer 1a of predetermined shape is printed and baded on the insulating substrate of alumina or the like, and a ferrite magnetic material layer 4 having a window and a closed circuit is printed and baked thereon while projecting both ends of the layer 1a. Thereafter, the upper conductor layer 1b is similarly printed and baked on the layer 4 while connecting the layer 1b at the end to the layer 1a. Thus, a film-shaped coil formed of the layers 1a and 1b interposed with the layer 4 therebetween is formed, and a solenoid type film-shaped coil having a wide formable inductance range and being easily trimmed can be obtained.

Title: Device for forming annular recessed section to bottom of drilled hole
Inventor: BINSENTO SANCHIESU BERASUKO
IPC: B28D1/14
Filed: 1987-01-05
Abstract: The invention refers to a device for the obtention of annular cavities at the bottom of drills made on surfaces of any kind. 
<??>The apparatus, which may be coupled to any motor element as a conventional drilling machine, incorporates an axle of a considerable length, edged in a cutter, provided with a rotating movement, which axle is housed in a cylindrical piece, in a sharply eccentric mode, said piece also receiving a rotating element with respect to the fixed body, of the apparatus in its whole, so that the cutter and the fixed body remain perfectly coaxial when introduced in the drill, and by rotating the cutter at a high speed, a slow rotating movement of the casing piece determines the progressive eccentricity of the cutter with respect to the fixed body, for the obtention of the annular cavity which is pursued. On the fixed body itself, in parallel with the axle of the cutter, and to the moving piece which houses it, is set forth a conduct for the refrigeration water of said cutter.

[Class 12 (i)] A ring for a thrust bearing comprises a solid steel annulus, which has a thickness substantially less than its radial width, and is coated with a thin layer of bearing metal over the whole of each of its two opposite faces. The bore may also be coated with the bearing metal, which may be a lead-bronze alloy, a leadcopper mixture or silver, and the ring may have a final coating of electrolytically deposited lead. A number of rings, A, may be coated simultaneously by placing them in a cylinder,F, spaced by rings G, introducing the bearing metal in a suitable form, such as swarf, and rotating the cylinder F in a furnace, so that the bearing metal is melted and deposited in the required thin layer on the opposite faces and inner edge of each ring A. When cool the rings are removed from the cylinder and the outer portions which are not coated, due to the thickness of the spacing rings G, are burred off. Alternatively, each ring may be packed in powdered metal and subjected to hydraulic pressure by which the metal is applied to the opposite faces of the ring. The ring may be used complete or in two or more segments, and oil grooves and depressions may be provided in its opposite faces.

Title: Improvements in engine-starters
IPC: F02N15/06
Filed: 1920-01-08
Abstract: 160,960. Rogers, F. H., (Eclipse Machine Co.). Jan. 8, 1920. Turning-gear.-In an engine starter comprising a hollow shaft 17 driven from a coaxial cylinder 5, and a driving-member or pinion 22 connected with the shaft for longitudinal and rotary movement, the hollow shaft 17 and the connection between this shaft and the cylinder are supported by a fixed central shaft 8. In one form, Fig. 3, the pinion 22 has a shell extension 23, 25 threaded upon the screw shaft 17, which is driven from the coaxial cylinder 5 through a coiled spring 15 secured to driving-heads 16, 13 upon the screw shaft and upon the end plate 12 of the cylinder. The pinion, screw shaft, and driving-heads are freely rotatable on the central shaft 8, and the cylinder 5 is driven from the electric or other starting-motor by means of a pinion on the motor shaft and a gear-wheel 3 on the end of the cylinder. When the pinion 22 moves longitudinally into mesh with the engine fly-wheel, the surface 34 of the shell extension 23 is supported in a bearing in the end of the cylinder 6. In a modification, the bearing is formed in the end of an additional cylinder carried by a flange on the screw shaft and fitting closely in the inner end of the cylinder 5. In a further form, Fig. 7, the longitudinal movement of the pinion 22 is facilitated by gravity pins 38 slidable radially in a part 37 of the shell 23, the upper pin resting in one of the grooves 40 in the stationary shaft 8 and riding out of the groove when the pinion has moved into mesh with the fly-wheel. The lower pin rides over a shoulder 41 in the cylinder 5. When the engine starts, the pinion 22 is over-run and returns along the screw shaft; the rotation throws the pins 38 outwards by centrifugal action, and the shoulders 41 co-operate with the pins to prevent the return of the pinion while the rotation centinues.

Title: Improvements in or relating to frequency divider circuit arrangements
IPC: H03B21/02
Filed: 1963-01-07
Abstract: 994,230. Frequency dividers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 7, 1963 [Jan. 10, 1962], No. 704/63. Heading H3F. The invention relates to a frequency divider of the type in which the divided frequency (#o) is obtained from the output of a mixer, to one input of which is applied the frequency to be divided ( #t=3#o) and to the other the beat frequency (2fo) necessary to obtain the desired frequency in the mixer output, the beat frequency being obtained from this output frequency by means of a frequency multiplier. In an embodiment the mixer comprises a balanced diode modulator 1, the beating frequency (2fo) being fed to the tuned primary 16 of a transformer with centre-tapped secondary 13 and the output beat frequency (fo) taken from the tuned secondary 18 of a transformer with centretapped primary 23. The frequency to be divided (#t = 3#o) is fed in between the two centre taps by means of a transformer 19. The beat output (fo) is fed via an amplifier 25 to the tuned primary 27 of a transformer the secondary 28 of which is centre-tapped and constitutes with diodes 29, 30 a frequency-doubler 6, feeding the requisite beating frequency (2#o) back to the transformer primary 16 via line 31. According to the invention there is interposed the limiter 32 having grid resistor 33, to which is applied not only the beating frequency (2fo) but also the negative-going D.C. output from the frequency-doubler 6. For starting purposes a signal at the divided frequency (#o) may be fed into the feedback loop via transformer 5. The arrangement is more particularly intended for use in colour television receivers, in which it is important that the loop gain of the dividing circuit should readjust itself to unity quickly at the start of each line scan. To this end, if the input capacity of the limiter 32 is such as to limit the rate of operation, a peaking coil may be included in series with the grid resistor 33.
