Title: Detecting method for defect of inverter
Inventor: NEMOTO YOUICHI
IPC: H02M7/515
Filed: 1981-07-13
Abstract: PURPOSE:To readily detect the defect of a gate circuit by instructing a gate pulse for causing a DC shortcircuit at an inverter and detecting the presence or absence of a main circuit current in this case. CONSTITUTION:When a gate signal is applied to the thyristors 4-1, 4-3 of an inverter 4 synchronously with the gate signal of a certain phase of a rectifier 2, the rectifier 2 is shortcircuited through a smoothing reactor 3, thereby operating in zero power factor. When a defect occurs in a gate pulse generator 10, a gate pulse control circuit 9 or a gate pulse transmitter 11-1 so that the gate pulse is not transmitted to the thyristors 4-1, 4-3, a current does not flow to the main circuit. When the presence or absence of the current is detected by a current detector 8, the defect of the gate circuit can be observed. When the gate signal is applied also to the thyristors 4-2, 4-4 in the same manner to detect the presence or absence of the current, the defect of the gate circuit can be observed.

Title: Special pattern detecting system of disk device
Inventor: TSUKIYAMA TOKUHIRO
IPC: G11B20/10
Filed: 1984-05-30
Abstract: PURPOSE:To improve a detecting reliability of an SM (sector mark) signal, and also to improve a reliability of a sector jump by providing a sensor circuit for writing an SM mark in the same position as the SM signal and detecting independently its SM mark, and counting the number of sectors by OR of both detecting signals. CONSTITUTION:When a sector of one sector before, the instance, a sector 63 is in a sector jump operating position, an SM marker 100 is marked by a width for covering enough a corresponding SM signal 101 extending from the trailing edge of its position to the leading edge of the next sector 0', therefore, an emitted light of a light emitting circuit 1 irradiates the marker 100 before the SM signal 101 of the next sector. Its reflected light is photodetected by a circuit 2, its waveform is shaped by an SM mark detecting circuit 8, and it is counted up by an SM counter 7 through an OR circuit 6. An output signal of the detecting circuit 8 is brought to waveform shaping enough even if a noise is generated by the circuit 2, and thereafter, converted to a digital signal. Also, an output pulse width of the detecting signal 8 covers enough the pulse width of an SM signal detecting circuit 5, therefore, even if the SM mark 100 or the SM signal 101 cannot be detected, the SM counter 7 executes counting exactly.

Abstract: PURPOSE:To utilize the advantages of a TCI transmission system and to transmit a high definition color picture signal efficiently through a single circuit by omitting a luminance signal, chrominance signal, and horizontal signal partially in a balances state and multiplexing them on time-division basis. CONSTITUTION:The luminance signal (Y) is encoded by an A-D converter 1-1 with a clock signal and then passed through 1-line memories 3-1 and 3-2, an adder 4-1, and a coefficient device 5-1 successively, and the interline difference signal of the luminance signal (Y) is obtained at the output side of a subtracter 11-1. The line-sequence chrominance signal (C), on the other hand, is sampled by an A-D converter 2 at a 24.3MHz sampling frequency and its timing is adjusted to the luminance signal by a delay circuit 8-2. Then, the luminance signal and chrominance signal are switched within each line period by a changeover switch SW3 to be multiplexed on time-division basis. The resulting time-division multiplex signal is passed through a D-A converter 9-1 and a low-pass filter 10-1 successively lastly to obtain a composite analog color picture signal.

Title: Automatic focusing device
Inventor: ITOU MASATOSHI
IPC: G02B7/32
Filed: 1983-06-16
Abstract: PURPOSE:To hold down the level shift to a step width even if a distance measuring signal level is outside a focusing zone because of influences of an external noise and a circuit internal noise, by performing the level shift in the focusing zone stepwise with the step width which is >=1/2 of the focusing zone. CONSTITUTION:A slider driving means 12 is provided which moves sliders 5 and 6 in accordance with a photographic lens 1 and shifts levels of a higher comparison voltage VH and lower comparison voltage VL so that a memory voltage is within the level range of the focusing zone. Plural taps 13 which can be brought into contact with sliders 5 and 6 by sliding are connected to a slide resistor 7 at equal intervals of <=1/2 of the width between sliders 5 and 6 which corresponds to the focusing zone. With respect to variation of sliders 5 and 6 due to the variation of the memory voltage accompanied with noise (the photographic lens 1 is moved forward or backward simultaneously), the level shift can be held down to a quantity corresponding to one divided zone if the level variation of the memory voltage is within one divided zone on the outside of the focusing zone. Consequently, hunting of the photographic lens 1 is held down to a narrow width in accordance with the width of the divided zone.

Abstract: PURPOSE:To eliminate a spring and to save adjusting by providing mechanism for applying pre-pressure between the bottom wall of housing and a bearing while applying proper axial pre-pressure of atmosphere in an atmospheric chamber onto the bearing through a bearing stopper member having a pressure receiving face. CONSTITUTION:Mechanism 13 for applying proper axial pre-pressure of atmosphere in an atmospheric chamber 15 through a bearing stopper member 14 onto the bearings 7, 8 is provided between the bottom wall 1a' of housing and the bearing 8. Atmospheric air is fed continuously through a hole 18 into said chamber 15. Upon high speed rotation of rotor drive shaft 5 through a motor 9, the rotor blade 6a will rotate integrally with high speed thus to evacuate the vacuum chamber 2. Consequently, the differential pressure produced between the vacuum chamber 2 and the atmospheric chamber 15 will cause application of proper axial pre-pressure onto the bearings 7, 8 through a shaft stopper member 14 having a pressure receiving face 16. As a result, spring load regulation is not required to save manpower required for adjusting while the spring is not required to reduce the number of parts and the price.
