Title: Abrasion-proof non-magnetic main shaft
Inventor: NAKAMURA KEN
IPC: F16C3/02
Filed: 1982-09-29
Abstract: PURPOSE:To obtain an abrasion-proof main shaft also to be non-magnetic by using non-magnetic high Mn alloy steel for manufacturing it. CONSTITUTION:This main shaft is made of high manganese non-magnetic alloy steel characteristic of hardness over Hv 350 and the maximum permeability (mumax) under 1.01. When the maximum permeability (mumax) is over 1.01, the main shaft is magnetized after a long time use. So it is desirably under 1.008mu, and needed to be under 1.01 to be within a practical range. When vickers hardness is under Hv 350, the contact with a bearing often causes scratches, and Young's modulus is also reduced to reduce rigidity. So the hardness must be at least over Hv 350. The captioned main shaft can be obtained by using non- magnetic high Mn alloy steel of the maximum permeability (mumax) over 1.01 and hardness over Hv 350 for manufacturing it. The proper material is, for example, an age-hardening austenite hot metal mold steel composed of 0.04- 1.0%, less than 2.0% SiO, 8-15% Mn, 1.5-3.0% Ni, 5-15% Cr, 1.5-2.6% V, and the remainder Fe, besides containing some of inevitable impurities.

Abstract: PURPOSE:To simplify a circuit eliminating the need for an expensive BPF by frequency-converting by the use of a VCO oscillating at a frequency which is an integer number times of the sum of the frequency of a carrier chrominance signal and of a low frequency conversion chrominance signal. CONSTITUTION:The low frequency conversion chrominance signal fSL is given to a first frequency conversion circuit 3. The output of the VCO 15 oscillating at the frequency which is B-number times of the sum of the frequency of the carrier chrominance signal fs and of the signal fSL is frequency-divided by a 1/B frequency divider circuit 24, and given to the circuit 3 through a phase shift circuit 25. Only the signal f3 of the output of the circuit 3 passes through the BPF 12, and only a burst signal within it passes through a burst gate circuit 13 and is given to a phase comparator circuit 22. The circuit 22 is given the signal from an oscillation circuit 16 through a 1/A frequency divider circuit 23, and a voltage corresponding to a phase difference is fed back to the VCO 15. The output of the VCO 15 is given to a second frequency conversion circuit 17 through a 1/C frequency divider circuit 18, and through an JOF 20 the signal fSL controls the VCO 15 through a side lock prevention circuit 19.

IPC: H02P29/04
Filed: 1984-08-16
Abstract: PURPOSE:To enable highly frequent inching by outputting a frequency command by a frequency based on a speed input from speed detecting means at brake releasing time. CONSTITUTION:The rotating speed of a motor 1 is always detected by a tachometer generator 14, and input to a frequency command generator 6. When a controller 5 is set to a stop notch, brake contactors 11a-11c become OFF, a brake 10 operates to interrupt a frequency command 7. In order to immediately restart it, the stop notch of the controller 5 is released to advance the notch. Then, brake contactors 11a-11c become ON. At this time, a frequency command generator 6 outputs the frequency command 7 to an inverter 2 by the frequency corresponding to the speed input from the generator 14 when the restart command is input.

Abstract: PURPOSE:To suppress a disturbance due to the erasing of a pattern to minimum by changing a reference of a control means for controlling a change over of a color difference signal in accordance with a change over of a video signal to a mute or the like during feeding a track or the like. CONSTITUTION:When a user desires to feed a head 5 between tracks, the operates a remote control 17 and feeds a signal to a photodetecting part 16. The signal is converted to a pulse 18 and fed to a CPU 15. For instance, if this signal 18 is signal for moving the head 5 from the first track to the 20-th track, a video signal is not inputted to an encoder 9, however, a subcarrier signal 22, a composite synchronous signal 23 and a character signal 24 and a burst flag 25 are inputted. Consequently, a video signal 26 to which the com posite synchronous signal and a burst signal are added is outputted from the encoder 9, so that for instance a black screen appears on a monitor 10. At this time, since a change over control signal 36 of a switch SW2 is changed over several H before of a vertical synchronous signal, or before a blanking period, it can be clearly erased on the monitor.
