Patent JP-H0340480-A (JP)
Title: Semiconductor ring laser
Inventor: IKEDA MASAHIRO
IPC: H01S5/00
Filed: 1989-07-07
Abstract: PURPOSE:To improve a semiconductor ring laser in light extraction efficiency by a method wherein light oscillating in a ring type waveguide is reflected by a high reflective film, and the reflected light is fed back again to the ring type waveguide, which is taken out through a half mirror. CONSTITUTION:A part of light circulating clockwise in a ring waveguide 12 propagates through an output waveguide 17 and reflected by a high reflective film 19, and a part of the reflected light is fed back as light circulating counterclockwise. By this constitution, light oscillating in the waveguide 12 is limited to light which is large in feedback volume and circulates counterclockwise and a light standing wave is not generated, so that the spatial hole burning of gain never occurs. In result, a longitudinal mode oscillation is restrained and a ring laser of this design oscillates in a single mode, so that it can be made to operate as a light source of high purity. By this setup, a large output can be taken out from an output waveguide 16.

Title: Controlled power circuit
Inventor: SUZUKI MANABU
IPC: H02M3/28
Filed: 1990-07-06
Abstract: PURPOSE:To facilitate a circuit by supplying the output of the low voltage terminal of a secondary coil, which supplies +B voltage, to an error amplifier, in place of controlling the output voltage of a controlled power circuit by the +E voltage on high voltage side. CONSTITUTION:This is so made that the DC voltage E1 of a video system is compared with reference voltage Ez in a differential amplifier OP, that the output is supplied to the control winding Lco of an orthogonal coupling type CPT through an amplifier PA, and that the permeability of a transformer changes by the control current flowing in this control winding Lco. Accordingly, this is controlled so that, when the load of DC voltage E changes and the voltage value lowers, the current flowing in this control winding may decrease, and that the permeability of the orthogonal coupling type transformer may be high. Moreover, the current, which is supplied to the DC voltage B supplied to a deflecting high voltage circuit, also changes approximately in proportion to the level of brightness. Accordingly, stabilizing the voltage on the side of DC voltage E, it follows that the side of DC voltage is stabilized.
