Patent JP-H08223038-A (JP)
Title: Pll circuit
Inventor: TSUNETOMI HIROSHI
IPC: H03L7/18
Filed: 1995-02-17
Abstract: PURPOSE: To provide a PLL circuit which assures the operations to be carried out right after a loop is formed and can shorten its starting time. CONSTITUTION: A phase comparator 5 outputs a clock that is synchronized with a reference signal 2 of the 1st input, and a voltage controlled oscillator 7 inputs the output signal of the comparator 5 through a filter 6 and then oscillates. A frequency divider 8 divides the output of the oscillator 7. In such a constitution of a PLL circuit, the in-phase signals are inputted to the 1st and 2nd inputs of the comparator 5 when no loop is formed. Then a starting signal synchronization circuit 3 produces a starting signal that is synchronized with the signal 2 while the comparator 5 and the filter 6 are kept in almost stable states. The frequency divider 8 si reset by the starting signal of the circuit 3 and at the same time a switching circuit 4 is switched to input the frequency dividing output OUT of the frequency divider 8 to the 2nd input of the comparator 5.

Abstract: PROBLEM TO BE SOLVED: To reduce a margin for machining by placing positioning jigs in direct contact with a protrusion in an outer wall surface of a displacer and a protrusion in an inner wall surface of a cylinder for machining. SOLUTION: A blank of a displacer 5 is obtained through sintering of a mold formed by powder metallurgy. During positioning, the displacer 5 is set up so that all fixtures 23, 24a, 24b, 24c fit into respective predetermined holes by using a robot and manual labor. At this time, the layout of holes 25a, 25b, 25c into which T-shaped fixtures are inserted and positioning jigs 21a, 21b, 21c is determined. Then, the displacer 5 is rotated and/or translated within a range restricted by a fixture 23 inserted in a shaft hole 6b so that the displacer 5 is in contact with each of all positioning jigs 21a, 21b, 21c. The blank is thereafter finished to an outline profile through grinding or cutting. This construction minimizes a margin for machining.

Filed: 1983-02-25
Abstract: PURPOSE:To obtain spheroidal graphite cast iron with high strength and toughness at a low cost in a shortened working stage by rapidly cooling a casting from a temp. above the A1 transformation point, suspending the cooling once, and slowly dropping the temp. CONSTITUTION:A molten metal having the composition of shperoidal graphite cast iron is charged into a casting mold, solidified, and held at a prescribed temp. The resulting casting is taken out of the mold, and it is rapidly cooled from a temp. above the A1 transformation point at such a cooling rate as to cause no pearlitic transformation. The cooling is suspended once at a temp. above the Ms point, and the temp. is slowly dropped after the lapse of a prescribed time.

Abstract: PURPOSE:To maintain the oscillation period of an oscillation system stably with high precision by feeding the output electric signal of a detection system back to a pulse generating circuit and controlling the generation period of a pulse train outputted from the pulse generating circuit. CONSTITUTION:The motion state of a reflecting mirror 2 fixed to an oscillator 1 is detected by the motion detection system 9 to obtain an electric signal which has a repetitive period equal to the motion of the reflecting mirror 2 (oscillator 1). The output signal of the motion detection system 9 is amplified 10 and branched to two paths; one is applied to a detecting circuit 11 to detect its envelope, which is compared with the voltage of a reference voltage source 13. The output of the comparison 12 is applied to a pulse width modulating circuit 7, which imposes PWM modulation. The PWM waveform is amplified 8 and then applied to a solenoid coil 4. The other output signal from the motion detection system 9 is waveform-shaped 14 and then applied to the pulse generating circuit 5. Thus, the feedback loop to the pulse generating circuit 5 is formed and the output period of the pulse train outputted from the pulse generating circuit 5 is specified by the period of the input signal from the waveform shaping circuit 14.

Abstract: PURPOSE:To provide an electrophotographic sensitive body small in deterioration of photosensitivity even in repeated uses by incorporating a trisazo compd. CONSTITUTION:A trisazo compd. acting as a photoconductor generating electrostatic charge carriers with extremely high efficiency upon absorption of light is represented by general formula I in which Z is one of formulae II; R<6> is H, lower alkyl, aryl, each optionally substd.; A is one of formulae III-VIII; and B<1>, B<2>, and B<3> are each H, halogen, or optionally substd. lower alkyl or such alkoxy, and they may be same or different. The generated carriers may be transferred with said trisazo compd. as a medium, but it is efficient to use a charge carrier transfer material as the medium for transferring the carriers. Since this electrophotographic sensitive body is generally high in sensitivity and superior in durability, it can be used not only for electrophotographic copying machines, but also for the wide fields of the photosensitive bodies of printers using laser, cathode ray tubes as light sources. Also, it can be used as photoconductive colored particles in the photoelectrophoretic system, and as colored particles in the dry or wet electrophotographic developer.
