Title: Signal separation circuit
Inventor: SEKIYA MASATAKA
IPC: G11B15/467
Filed: 1984-03-12
Abstract: PURPOSE:To realize a circuit having a scale suitable for circuit integration by providing a function detecting a wide pulse and a function frequency-dividing the wide pulse to a single counter and allowing the counter to detect the wide pulse subject to frequency division from a synthesizing signal from a narrow pulse and the wide pulse to decrease the numbers of elements. CONSTITUTION:When an output signal (g) of a flip-flop circuit FF31 is at H level, a vertical synchronizing signal of a composite synchronizing signal (a) is detected and when at L level, no vertical synchronizing signal is detected. Thus, the vertical synchronizing signal located at an interval of one is detected from the composite synchronizing signal (a). The detection function and frequency division function of the vertical synchronizing signal are provided to the counter 4 by switching a reference value of the up-down counter 4 and the vertical synchronizing signal subject to 1/2 frequency division is obtained directly from the composite synchronizing signal by using the single counter, then only one set of the counter is enough, allowing to constitute the circuit scale to a very small value, then the chip size goes to very small in case of circuit integration.

Abstract: PURPOSE: To generate the musical tone sounds, to which the aging of the harmonic construction  is imparted, by dividing the one cycle waveform of a key depression tone into a plurality of  blocks thereby to control the rising and breaking amplitude and curve of the waveform of each  block.  
     CONSTITUTION: In response to the counted step signals of a tone clock frequency control circuit  2 according to the key depression tone code from a tone input code register 1, the one cycle of  the musical sound waveform corresponding to the tone is divided by a waveform synchronous  counting circuit into a plurality of blocks so that the waveform codes of each block are fed  through a decoder 4 thereby to address a program designating unit 5. This unit 5 generates the  coefficient value including the up and down for the waveform amplitude control of each block  thereby to impress it upon a multiplying circuit 6. On the other hand, the circuit 6 is supplied  from an envelope counter 7 with an envelope coefficient according to the time laspe of the key  depression and to the volume code. As a result, the circuit 6, an adder 8 and a summing device  9 simultaneously generate the musical sounds of different waveforms, and the chords to which  the aging change of the harmonic construction are effectively imparted can be generated with  the use of a simple construction.

Title: Exhaust gas return control device for diesel engine
Inventor: NISHIMURA HIROYUKI
IPC: F02M25/07
Filed: 1989-02-27
Abstract: PURPOSE:To prevent the occurrence of a torque shock by a method wherein when the number of revolutions of an engine exceeds a given value, a speed at which an exhaust gas return valve is closed is controlled to a low value, and when the number of revolutions of an engine is below the given value, a speed at which the exhaust gas return valve is closed is controlled to a high value. CONSTITUTION:A control unit 30, based on an engine load detecting signal, throttles the passage area of a negative pressure passage 24 to a given value in a high number of revolutions of engine running region, in which the high number of revolutions of an engine exceeds a given value, by means of a negative pressure throttle valve 27. The control unit fully closes the passage area of the negative pressure passage 24 when the number of revolutions of an engine is below a given value. Thus, in the high number of revolutions of engine running region, a change in a pressure in a negative pressure chamber 21 is only gradually produced, the opening and closing speed of an exhaust gas return passage 8 by means of an exhaust gas return valve 9 is reduced, and exhaust gas return is gradually suspended or restarted. This constitution prevents the occurrence of a torque shock through suspension or restart of exhaust gas return, and keeps a running feeling at an excellent state.

Filed: 1987-02-27
Abstract: PURPOSE:To speed up a registered number change operation by changing a stepping direction only in the place where a correction is required according to need and resetting the once set registered numbers when said registered numbers are desired to be changed. CONSTITUTION:For example, registered number setting keys 3, 4 for a number of copies provided to a control panel are provided in plural pieces in corresponding to the respective places. The registered numbers of the places corresponding to the keys 3, 4 are, for example, incremented and the number after 9 is 0 when only the above-mentioned keys are operated. However, a decrement mode is set when the keys 3, 4 and a mode change-over means 5 are simultaneously operated and, therefore, the registered numbers of the places corresponding to the keys 3, 4 decrease successively so that the number after 0 is 9. The registered number of the unit place, consequently, changes from 6 to 5, 4 when the key 3 for the unit place and the mode change-over means are both operated when, for example, 56 is desired to be changed to 54.

Title: Method for removing carbon monoxide from gas stream and device therefor
Inventor: FUREDERITSUKU DABURIYU JIYAKOB
IPC: C01B21/04
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a device and method for removing carbon monoxide from a gas stream consisting essentially of an inert gas and contg. a small amt. of carbon monoxide. SOLUTION: A gas stream supplied is brought into contact with a main metal oxide in the reaction region of a reaction vessel under conditions effective to convert substantially all the carbon monoxide to carbon dioxide to produce a refined gas consisting essentially of an inert gas and carbon dioxide and practically free from carbon monoxide by this method.  In the method, oxygen in a gaseous nitrogen stream is produced from the conventional air separation system with the concn. changed in the vicinity of a set value, then the excess oxygen in the nitrogen is converted into carbon monoxide and carbon dioxide by the use of a gaseous fuel/combustion process by which the carbon monoxide concn. is changed with a change in the oxygen concn. in the oxygen concn. in the gas stream supplied to the combustion process, hence a gaseous nitrogen source further refined is obtained, and a gaseous nitrogen source further refined to a higher degree is produced from the obtained gaseous nitrogen source by this useful method.
