IPC: H04N7/08
Filed: 1987-03-27
Abstract: PURPOSE:To reproduce a multiplex signal excellently by providing a means for applying carrier wave elimination to a signal being brought into a residual side band by a Nyquist filter having amplitude characteristics symmetrical in odd number with respect to a video carrier frequency during a blanking period and superimposing the result on a television signal. CONSTITUTION:High-frequency components 4.2-5.2MHz of a luminance signal are subjected to frequency conversion by subcarriers of 4.2MHz so as to have a frequency of 0-1.0MHz. In this case, the phase of the subcarrier is controlled so as to be inverted by a phase controller 15 for each horizontal scanning period, for one field or for one frame. The signal subjected to frequency conversion by the subcarrier of the phase as above is given to a modulator 11. The carrier P1 obtained from an oscillator 9 is modulated in terms of amplitude by an amplitude modulator 7 by using an output signal of an adder 6. The obtained amplitude modulation wave is subjected to band limit by a 1st filter 8 to form a residual-side band and the result is fed to an adder 13. The carrier P1 shifted in terms of phase by 90 deg. by the phase shifter 10 is used as the carrier P2. The carrier P2 is subjected to double-side band amplitude modulation by using the output signal of the frequency converter 5 at the modulator 11 and the result is subjected to carrier wave elimination double-side band amplitude modulation during the blanking period.

Title: Control device of copying sheet number
Inventor: TAKAHASHI MASAKI
IPC: G03G21/00
Filed: 1983-04-30
Abstract: PURPOSE:To prevent generation of an operation error, and to obtain a titled device at a low cost by inhibiting a large quantity copying mode by rewriting a data in a nonvolatile memory, or releasing this limit. CONSTITUTION:When a stop button is pushed, a CPU41 discriminates whether a main motor is rotating or not. A main motor driving controlling circuit 52 executes an interruption to the CPU41, and if the main motor is on, a control for stopping it is executed. On the other hand, if the main motor is in an off- state, an on-off state of a flag of a nonvolatile memory 22 is checked, and it is transferred to the CPU41 through a large quantity copying mode setting circuit 49. In case the flag of the nonvolatile memory 22 is on, the CPU41 checks a register in the large quantity copying mode setting circuit 49, and discriminates whether a device is set already to a large quantity copying mode or not. If it is not set to the large quantity copying mode yet, the setting is executed, and if it is set to the large quantity copying mode already, the release is executed. Accordingly, the large quantity copying mode can be inhibited and this limit can be released, therefore, it is possible to cope with an accidental variation of a using state.

Filed: 1985-04-09
Abstract: PURPOSE:To obtain a microphone of excellent performance with high output by using a disk like hollow and flat coil of a minimum moving mass and operating it in a reciprocating strong magnetic field. CONSTITUTION:A reference numeral 1 shows a cone diaphragm, 2 a disk like hollow and flat coil on which an insulated fine line is wounded. This is situated in an air gap formed by armature sections 4, 5. The armature sections 4, 5 are constituted by holding an upper and a lower sections of flat magnets 6, 7 by pole pieces 8, 9 and 10, 11 respectively. The polarities of the flat magnets 6, 7 are opposite so as to form counter electrodes by the pole pieces 8, 9 and 10, 11, respectively. The air gap 12 is made smaller than the thickness of the flat magnet. A reference numeral 13 designates a hollow section of the flat coil. A diameter of this hollow is substantially the thickness of the magnet. The thickness of the pole piece is substantially the height of the semicylindrical sections 13, 14 in the coil. Since the coil constituted in this manner is operated in a reciprocating strong magnetic field, an extremely efficient microphone generating system is obtained.

Title: Distributed feedback type semiconductor laser
Inventor: NISHIMURA MICHIYO
IPC: H01S5/12
Filed: 1988-03-28
Abstract: PURPOSE:To obtain a stable single mode oscillation very efficiently by a method wherein a diffraction grating is composed of a laser active layer in which regions provided with a super lattice structure and other regions provided with a disordered super lattice structure are periodically arranged. CONSTITUTION:A laser active layer is provided, where regions 11 provided with a super lattice structure and other regions 12 provided with a disordered super lattice structure are periodically arranged in a direction R of the resonance. The regions 12 whose super lattice structure is disordered is mixedly crystallized and different from the regions 11 of a super lattice structure in a band gap energy and a refractive index. Therefore, the laser active layer 16 possessed of a periodical gain distribution in a resonating direction constitutes a diffraction grating. Here, when a current is made to flow between electrodes 20 and 21, light rays radiate owing to the recoupling of carriers in the laser active layer 16. The radiated light rays resonate in the stripe-like region in a direction of R, and laser rays L are projected from the end face of the laser. By these processes, a single mode oscillation high in efficiency and stability can be obtained.

Abstract: PURPOSE:To realize the automatic analysis of a trouble by storing previously a rule to specify the trouble element from various conditions, estimating the trouble element from the satisfactoriness of the rule conditions and furthermore inverting the trouble element to simulate a sequence program and to specify the trouble element. CONSTITUTION:A numerical controller 1 decides that a tool exchanging device 10 has a fault and delivers and error signal to a CPU 5 in case no tool change end signal is supplied even though a fixed time passed after output of a prescribed code. Then the cycle where the processing is interrupted is estimated since a state data memory area IOS of a RAM 6 stores the input/output state data on each working cycle. Then the satisfactoriness is decided for the rule stored in a knowledge base memory area IDB. When the extraction of an applied rule is through, a sequence program is simulated. Thus the relevant input/output element is specified as a genuine trouble element as long as a cycle ens normally when the state of an input/output element estimated as a trouble in an interrupted state is inverted.

Abstract: PURPOSE:To supply electric current stably to a laser diode while switching it at a high speed, by utilizing the laser diode and an impedance element as loads having equivalent characteristics and altenately switching the loads according to a two-value driving signal so as to connect it to a constant current source. CONSTITUTION:A diode 1 is supplied by a constant current source 3 and connected in series to a transistor Tr7. A signal Vin is applied to the base thereof through an inverter 10. When the signal Vin is 'H', the diode 1 emits light. A transistor 8 is supplied by the constant current source 3 in common with the diode 1 and a voltage drop thereof is determined by a constant voltage V1 at a level equal to that of the diode 1 during operation. A transistor Tr9 has characteristics similar to those of the transistor Tr7 and is connected in series to the Tr8. A signal Vin is applied to the base of the Tr9 so that the Tr8 is operated as a load of the constant current source when the signal Vin is 'H'. Accordingly, since the constant current source supplies current to equivalent loads regardless the diode is ON or OFF, a potential across the load is, not varied and the diode can be switched at a high speed.
