IPC: B05D1/08
Filed: 1983-02-10
Abstract: PURPOSE:To increase adhesion strength of a molten metal onto a surface to be melt-sprayed by calculating a heat input by the feed speed of a metallic wire on a positive pole side and arc current and setting the respective feed speeds of both metallic wires so as to maximize the heat input to be supplied to both metallic wires. CONSTITUTION:Metallic wires 1, 2 on a positive pole side and a negative pole side are respectively fed and an arc is generated between the top ends of both metallic wires to melt both metallic wires. Compressed air 7 is fed to a melt spraying gun 5 to spray the molten metal to an object 8 to be melt-sprayed. Both metallic wires are fed respectively at the individual feeds speeds and the feed speeds are adjusted, then the arc currents of the arc are measured with respective ammeters 9, 10. The heat input to be supplied to both metallic wires is calculated from the arc currents and the feed speeds. The feed speeds of both metallic wires are respectively set to as to maximize the heat intput.

Title: Azimuth supervising system for aircraft
Inventor: OSHIDA NAOTO
IPC: G01S3/16
Filed: 1985-02-06
Abstract: PURPOSE:To obtain the azimuth of an aircraft by storing a interrogation signal from the aircraft which is modulated by the rotation of an antenna and forming an envelope corresponding to the angle of rotation. CONSTITUTION:The interrogation signal from the aircraft is received by a receiver 200 through a TACAN(tactical air navigation) antenna 100 and only part of the received signal which is made into a TACAN signal by a decoder 300 is regarded as the interrogation signal. In such a case, the interrogation signal from an aircraft station is much less in the number of transmit pulses per second than a transmit signal from a ground station and any envelope can not be formed in this state. For such a purpose, a identifying circuit 3400 identifies the receive signal as the interrogation signal of each aircraft and the antenna pattern direction and reception level when the signal is received by a storage circuit 500 are recorded and stored. Those stored receive signal levels are read out successively by a reading circuit 600 to form an envelope necessary for azimuth measurement. An azimuth measuring circuit 700 decides the azimuth of each craft from the phase of the envelope and the azimuth is displayed on a display device 800.

Title: Tapping brush printer with ink applier
Inventor: RUDORUFU BIYUURAA
IPC: B41F17/14
Filed: 1983-02-10
Abstract: The swab printing machine is provided with an inking device having a carriage. A spreader support with a spreader head is tippably arranged on the frontal side of the carriage and can reciprocate over a printing plate. The spreader which is inclined backward by about 20 DEG , takes ink from the ink container during its forward motion and distributes it over the printing plate, whereby the two rounded slide feet achieve the uniform distribution of the ink. During the return motion the excess ink is wiped off by a doctor blade. A laterally running recess is arranged in the lower portion of the spreader and the lower edge of this recess forms a narrow dipping edge. An adjustable central closure is provided on the spreader support and on the spreader head. After the initial positioning of the spreader head it is possible to remove same, clean it and remount it, without making readjustments. Because of the narrow dipping edge, the same quantity of ink is always transported onto the printing plate, regardless of the immersion depth of the spreader.
