Patent JP-S63235973-A (JP)
Title: Magnetic circuit device
Inventor: SAKATA YOSHIO
IPC: G03G15/09
Filed: 1987-03-24
Abstract: PURPOSE:To prevent the drop and scattering of a toner carrier by allowing a magnetic field intensity vector being larger than the peak value of a radiation direction magnetic field on the sleeve of a developing magnetic pole, to exist within 45 deg. by a rotational angle from the center of the developing magnetic pole. CONSTITUTION:As for this magnetic circuit, the magnetic field intensity vector HA being larger than the peak value of a radiation direction magnetic field HR on the sleeve 3 of a developing magnetic pole exists in the vicinity of the developing magnetic pole, and also, its position is within 45 deg. by a rotational angle from the center of the developing magnetic pole. That is, the catching force of a toner carrier is not prescribed by a specified direction magnetic field component on the sleeve of a magnet roller, but regulated by the absolute value of a composite magnetic field vector obtained as the vector sum of each direction component. In such a way, even in the case of the magnetic roller in which the peak value of HR is relatively small, the catching force of the toner carrier is strong and the drop and scattering of toner are not generated as a matter of fact.

Abstract: PURPOSE: To prevent oil from being blown up by placing a discharge port away from the oil surface of an oil tank.  
     CONSTITUTION: The inlet port of rotor 3 is formed at the lower part of rotor 3, and the discharge port at the upper part of rotor 3. Cylindrical demister 7 is placed sideways at the upper part inside casing 5. Since the discharge port is placed away from the oil surface of oil tank 10, discharge gas 9 does not blow up oil 6 in oil tank 10. The mixture of gas and oil flows from the outside to the inside of demister 7, and oil is separated during this time. The gas separated from oil is discharged outside from discharge ports provided on both sides of demister 7. On the other hand, the separated oil drops into oil tank 10 in oil drops 11. Since demister 7 is cylindrical, it can enlarge the area of gas passage and reduce the flow speed, so that the oil separation efficiency can be increased.

Title: Octave conversion system

IPC: G10H1/02
Filed: 1978-06-13
Abstract: PURPOSE: To readily obtain the musical tone signal of the timbres close to those of natural tones by applying an envelope signal to a modulating signal and inputting the same to a voltage control amplifier when the sound source signal is on the specified level order.  
     CONSTITUTION: When the rectified voltage of a sound source signal by a rectifier circuit 6 exceeds threshold voltage, a comparator 7 products its output which in turn operates an envelope generating circuit 8 to generate the envelope signal which has been so set that its rise is fast and attenuates exponential-functionally and the attenuation time thereof becomes shorter than the envelope of the musical tone signals. This signal is combined with the modulating signal in a mixing circuit 4 and the composite signal inputs a voltage control amplifier 2. Since the constant C of the amplifier 2 changes with time according to this signal, the second order harmonic overtone signal is envelop-formed and if the even number order harmonic overtones other than this are contained, these are similarly envelope-formed. Thereby the musical tone signals of the timbres close to those of natural tones may be obtained.
