Title: Production of magnetic head for magnetic disk device
Inventor: ONODA TAKASHI
IPC: G11B5/455
Filed: 1994-09-29
Abstract: PURPOSE: To remove insulation coatings with high positional accuracy by previously removing the insulation coatings in the middle part of wires to be cut after measurement of electromagnetic conversion characteristics. CONSTITUTION: One end of plural pieces of the wires formed by cladding conductors with the insulation coatings is connected to a magnetic head element and the other end of the wires is connected to a connector (paddle board) 20 for measuring the electromagnetic conversion characteristics. The part 56 where the insulation coatings are partially removed over the prescribed length is formed between both ends of the wires and the electromagnetic conversion characteristics of the magnetic head element 12 are measured through the connector 20. The wire are thereafter cut at the point where the insulation coatings are removed and a magnetic head having the part where the insulation coatings are removed is constituted at the end of the wires.  The insulation coatings in the middle part of the wires cut after the measurement of the electromagnetic conversion characteristics are thereby previously removed and, therefore, the need for the operation to remove the insulation coatings at the time of a later operation, such as dipping into a solder tank, is eliminated.

Title: Movement adaptive still circuit
Inventor: YASUE NORIMI
IPC: H04N9/77
Filed: 1990-09-27
Abstract: PURPOSE:To display a still picture having high picture quality by providing an arithmetic circuit to output a chroma signal, and a second switch to normally select the chroma output from a movement adaptive Y/C separator circuit and to select the output signal of the arithmetic circuit in the case of a still operation. CONSTITUTION:A movement adaptive noninterlace converting circuit 19 receives a control signal and outputs it after executing a movement adaptive noninterlace conversion processing to a luminance signal outputted from an external field memory 8. On the other hand, a second switch 3 selects the output of an arithmetic circuit 4 at such a time, and the arithmetic circuit 4 subtracts the luminance signal outputted from the external field memory 8 and a composite video signal outputted from a movement adaptive Y/C separator circuit 18. As the result, therefore, the second switch 3 outputs the chroma signal to which a movement adaptive Y/C separation processing is executed. Thus, even in the case of a moving video, the still picture having the high picture quality can be displayed without cross color, cross luminance and picture deviation between fields as well.

Title: Waveguide type gas laser
Inventor: SUEDA TADASHI
IPC: H01S3/034
Filed: 1993-09-22
Abstract: PURPOSE:To extract a light beam which is uniformly distributed in the form of a sheet or plane by oscillating a laser through reflection of light with plane mirrors at both surfaces, extracting an output beam in the axial direction from one plane mirror and a lateral output beam which is distributed in the form of sheet from a transparent output window. CONSTITUTION:A composite type structure laser incorporates five waveguide spaces W1, W2, W3, W4, W5. The external surface of such a laser is formed as a waveguide path 12 made of dielectric material, but the area between the adjacent waveguide spaces W1 to W5 is formed of a thin separating plate 14. This separating plate 14 includes a gap 13 at a part thereof for coupling of wave functions between the adjacent waveguide spaces W1 to W5. Since the upper part of the waveguide path 12 is substituted by a transparent output window 15, the light is obliquely outputted from the output window 15 and is then dispersed in the direction where the waveguide spaces W1 to W5 are arranged. Moreover, since the light in the form of sheet is outputted from the one waveguide path, a plane type light beam can be emitted from the composite structure type laser. Therefore, high quality laser can be obtained because this light beam is dispersed like a plane, phase and frequency are orderly set and intensity of laser beam is uniform.

IPC: G01C19/5776
Filed: 1988-10-15
Abstract: PURPOSE:To achieve a stability in the detection of an angle of turning by integrating differences between output values of an angular velocity sensor in straight running and output values in turning. CONSTITUTION:When a body 1 is running to reap grain culms with a reaper 4, an output of an angular velocity sensor 6 is read into a turning controller 2 to be stored into a memory. Then, as a grain culm sensor 5 detects grain culms gone at the end of a reaping, after the body runs straight by a fixed distance, an output is produced to a left solenoid 8 through a drive circuit 7 from the device 2 to brake left and right running devices 3 and the body 1 starts turning to the left. At this point, output values of the sensor 6 are read into the device 2 at each time and differences are calculated and integrated from an output value stored during the straight running. Then, when a value thereof reaches a specified primary angle theta1 of turning, the output to the left solenoid 8 is stopped and the body 1 is retracted by a fixed distance once stopped. Then, at the end of the reaping, the body turns to the right at a secondary angle theta2 of turning and runs straight. Thus, the body 1 can shift to a reaping process sideways by turning.

Title: Heat transmission pipe externally exchanging heat
Inventor: SAKON YUZO
IPC: F28F1/36
Filed: 1987-10-15
Abstract: PURPOSE:To provide a heat transmission pipe which excels both in boiling and condensing performances by providing the heat transmission pipe with fins and spiral grooves, and performing the condensing on the fin side and the boiling with the spiral grooves and boiling enhancing nuclei disposed in the bottom of the groove. CONSTITUTION:At the time of condensing, fins 10 which cover most of the outer surface of a heat transmission pipe 5 have much chance of contact with the vaporized heating medium, and promote the nucleated condensation with their tips as nuclei. At the time of boiling, on the other hand, the liquid heating medium is in contact with the entire outer surface of the heat transmission pipe 5, and is most actively boiled in the bottom 13 of spiral grooves 11 where the temperature is higher than the fins 10 because of the closeness to the heat source flowing through the pipe. Since boiling enhancing nuclei 15 are formed in the groove bottom 13 with fine ribs 14, the nucleated boiling of heating medium can be physically enhanced in addition to the temperature condition. Further, as air bubbles generated at the groove bottom 13 rise because of their buoyancy, they contact the surface of the fin 10 adjacent to the spiral groove 11 to disturb the liquid film, improving the heat transmission through the fins 10.
