Title: Oscillation circuit
Inventor: KIYONO TAKEHIRO
IPC: H03B5/00
Filed: 1994-03-18
Abstract: PURPOSE:To provide a small-sized and stable oscillation circuit. CONSTITUTION:The feedback type oscillation circuit which oscillates by feedback of the output of an amplification stage 1 to the input is provided with a first 3-terminal active element 2, which is provided in series to the feedback loop of the oscillation circuit, and a first phase shift circuit 3 which shifts the phase of the signal fed back to the active element 2 by about integer-fold wavelength of a prescribed frequency to apply this signal to the control terminal of the active element 2. For example, the amplification stage 1 generates the output having the same phase as the input and feeds back a part of this output to the active element 2. The phase shift circuit 3 shifts the phase of the signal fed back to the active element 2 by about a wavelength of the prescribed frequency and applies this signal to the control terminal of the active element 2. In this case, the active element 2 allows signal components having the same phase as the input or the control terminal to pass through but shows a relatively large insertion loss for signal components having phases different from the phase of the input of the control terminal. That is, the active element 2 has the fixed band pass characteristic having this prescribed frequency as the center frequency. As the result, this oscillation circuit oscillates with the prescribed frequency.

Title: Optical pumping system atom beam oscillator
Inventor: KUDOME KENJI
IPC: G01J9/00
Filed: 1992-03-06
Abstract: PURPOSE:To simply control a frequency of a subordinate light and a reference light by making a frequency of the reference light coincident with an atom transition frequency and controlling the frequency of the subordinate light so that a difference between the frequency of the subordinate light and the frequency of the reference light is constant. CONSTITUTION:A phase comparator 37 compares a phase of a beat signal from a BPF 34 with a phase of a reference signal from a synthesizer 38 to output a phase error signal. Thus, an LD control circuit 39 controls a frequency of an output light of a reference light source LD2 so that the phase error signal is zero. On the other hand, a beat signal from the BPF 36 and a microwave signal from a microwave synthesizer 7 are mixed by a microwave mixer 40 and the result is down-converted into an intermediate frequency signal. The phase comparator 41 compares a phase of the intermediate frequency signal and a phase of a reference signal outputted from a synthesizer 42 to output a phase error signal. Thus, an LD control circuit 43 controls the frequency of the output light of a subordinate light source LD3 so as to make the phase error signal zero. The stable output light is emitted to an atom beam oscillator.

Title: Image forming device
Inventor: TANAKA SOHEI
IPC: B65H43/00
Filed: 1987-03-04
Abstract: PURPOSE:To prevent stagnation of sheets in a paper discharge section by providing a means for detecting the conveying time of a sheet in a paper feed section and a conveyance control means for driving the sheet discharge section for a time according to the conveying time of the sheet detected by the detecting means so as to convey the sheet. CONSTITUTION:When a sheet does not reach a paper discharge sensor 10 within a predetermined time from the turn-on timing of a registering roller 5, (time of movement of the sheet from the point (a) to the point (b) + marginal time), a delay due to a jam is detected. Further, when a sheet stays in the paper discharge sensor 10, exceeding a predetermined time from the timing at which the sheet enters into the paper discharge sensor 10, (the time of movement of a sheet having a maximum size capable of being used in the copying machine+marginal time), a stagnation due to a jam is detected. Further, when a sheet passes through the sensor 10 in the predetermined time, it is judged that the sheet is discharged so as to complete a copying sequence. Further, detection and control are made to obtain such a relationship that the amount of paper feed is greater than the amount of paper discharge. With this arrangement, it is possible to prevent stagnation of sheets in a sheet discharge section, and to minimize the rotating time of a motor M2.
