Title: Frequency synthesizer system receiver
Inventor: AKIYAMA TORU
IPC: H04B1/26
Filed: 1989-03-27
Abstract: PURPOSE:To reduce lockup time by selecting a reference frequency of a phase locked loop to a multiple M of a minimum broadcast frequency interval, frequency-dividing the oscillated output of a voltage controlled oscillator of the phase locked loop and utilizing the frequency division output as a local oscillation signal. CONSTITUTION:When a reference frequency fr' and an oscillated frequency fv' of a voltage controlled oscillation circuit 13' are multiplied by a factor of M, the frequency division ratio N' is expressed as N'=fv'/fr'=M.fv/M.fr=N and it is enough to be the same as a conventional example. Moreover, as to the minimum change frequency of the local oscillating frequency, the relation of DELTAfl=DELTAfv'/M=fr'/M=fr is obtained and this is the same as that of a conventional receiver. On the other hand, the natural angular frequency omegan' is expressed as omegan'=sq. rt. Kv'.Kp'.KL/N'=sq. rt. M.Kv.Kp.KL/N=sq. rt. M.omegan because the gain constant Kv' of the voltage controlled oscillator 13 is expressed as Kv'=M.Kv, then the natural angular frequency is a factor of sq. rt. M in comparison with a conventional receiver. Thus, the lockup time is decreased as a factor 1/sq. rt. M in comparison with a conventional receiver.

Filed: 1979-06-20
Abstract: PURPOSE: To uniform the reduction of the whole generating surface thickness of a rotating heat pipe-regenerator and to permit the low temperature-side deposit to be readily removed by rotating the casing provided around the fixed member containing heat pipes at a prescribed speed, and performing soot blowing.  
     CONSTITUTION: The high-temperature gas from an inlet duct 1 supplies heat for a group of heat pipes 8 while flowing, as shown by arrows 32, 33, 34, 35, 36, and 37, before being discharged from an outlet duct 2. On the other hand, the low-temperature gas from an inlet duct 3 absorbs heat from the heat pipes 8 while passing through space 28 between the heat pipes 8. A high temperature-side casing 12 is rotated at a speed of under 360°/min, or rotated for a specified time at regular intervals by driving a pin rack 43. Soot blowing is also performed by rotating the casing for a specified time. Thus, since the low temperature-side generating surface can be moved to the high-temperature side, the thickness reduction can be uniformed, and the low temperature-side deposit can be readily removed.

Title: Separating pawl device
Inventor: HARA YOSHINOBU
IPC: B65H29/56
Filed: 1987-03-30
Abstract: PURPOSE:To extend the life of a photosensitive body by controlling a holding member or separating pawl in such a manner that the contact time for pressing the tip part of the separating pawl to the photosensitive body is short at the time of vertical passage of paper and is long at the time of horizontal passage of the paper in accordance with the control signal from a control part at the time of separating the paper tightly sticking to the surface of the photosensitive body. CONSTITUTION:A sensor part 4 detects whether the paper 7 tightly sticking to the surface of the photosensitive body 10 is in a vertical passing state or horizontal passing state at the time of copying. The working time of a member 6 for moving the separating pawl is controlled by the control part 5 which makes computation in accordance with the input signal from the sensor part 4 and generates the control signal. The member is thus so controlled by the control part 5 that the time for pressing the separating pawl 2 to the body 10 is short at the time of the vertical passage of the paper and is long at the time of the horizontal passage. Since the pressing of the pawl 2 to the body 10 for the unnecessarily long time is averted, the damage of the body 10 by the pawl 2 is decreased.
