Title: Frequency divider
Inventor: HOTSUTA TOSHITSUNE
IPC: H03K23/66
Filed: 1982-06-28
Abstract: PURPOSE:To eliminate the need for the addition of a counter, even if the frame is long, by opening a gate with a final frequency dividing value, when a desired period is larger than the maximum frequency dividing value, in a frequency divider used for the production of a frame pulse. CONSTITUTION:An operating circuit 26 stores a variable M in its inside and the initial value of the variable M is taken as the final frequency dividing ratio N. The operating circuit 26 references the variable M in synchronizing with the count end pulse outputted from the counter 21, feeds the next calculating value, subtracts the preset value given from the variable M to counters 21-23 so that the period N in total is counted at the counters 21-23. When the variable M is M>2L, the counters 21-23 feed a preset value being the period L, and when M<=2L, the counters 21-23 feed the preset value being the period M. The frequency divider is controlled that the count end pulse of the counters is outputted externally only once per the period N.

Title: Optical transmission equipment
Inventor: KAIZUKA KENICHI
IPC: H04B10/293
Filed: 1987-05-06
Abstract: PURPOSE:To obtain a stable feedback signal by restraining the oscillation phenomenon in the control system of an equipment by generating an inverted signal by inverting the polarity of the second electric signal sent out from an amplifier by a polarity inverter and by integrating the difference of the inverted signal and a reference signal by supplying the inverted signal together with the reference signal to an integrator. CONSTITUTION:An integrator 15 guides an inverted signal 14 via the first resistance R1 and a reference signal 10 via the second resistance to an operational amplifier U1 respectively. Since the inverted signal 14 passes a polarity inverter 8, it has opposite polarity against the reference signal 10 and it supplied simultaneously to the positive electrode of the operational amplifier U1, the operational amplifier U1 integrates the difference of both the signals by the storage operation of a capacitor C1 and a feedback signal 12 is sent out. Since the integrator 15 integrates an input signal by the storage operation of the capacitor C1 and sends out in this way, when the rapidly changing inverted signal 14 is sent in the integrator 15, the integrator 15 sends out the slowly changing feedback signal 12. If the feedback signal 12 is changed slowly, stable light 4 can be obtained without a control system being accompanied by an oscillation phenomenon.

IPC: H01S3/16
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To improve a beam with respect to a widthwise direction of a slab-type laser medium by forming a light path, which turns via a turning mirror between a partial reflection mirror and a total reflection mirror, to have a slope angle with respect to the lengthwise axis of the slab-type laser medium, and outputting laser from the partial reflection mirror to the outside of a resonance device. SOLUTION: A partial reflection mirror 2 and a total reflection mirror 3 are provided parallel to each other, respectively at a sloped angle, to form a light path reciprocating between these mirrors via a turning mirror 4. At this time, there is a gap outwardly increasing between a forward light path and a reverse light path, and these is a triangular-shaped overlap area 20 where the forward and reverse light paths overlap with each other, at a position near the spherical mirror 4, while there is a triangular blank area 30 at a position far from the turning mirror 4. To cause laser oscillation at a high efficiency, many parts of a slab-type laser medium 1 are arranged in the overlap area 20.  Thus, by determining the entire arrangement to have a light path where a light beam which reciprocates in the resonance device passes through the slab-type laser medium 1 across almost entire width of the widthwise cross section of the slab-type laser medium 1, the beam with respect to the widthwise direction can be improved.
