Abstract: PURPOSE:To obtain the optical amplifier which obtains a high gain without increasing the cost of a device as to the optical amplifier of an optical communication system. CONSTITUTION:An input signal is applied to the optical amplifier 1 through a coupling means 3 and amplified, the amplified signal is applied to a state converting means 2, and changed in state and separated into two states, and one is outputted while the other is fed back to the coupling means 3; while the same plane of polarization with the input signal as to a light signal obtained by rotating a polarized wave by, for example, 90 deg. through the state converting means 2 is outputted, the different plane of polarization is inputted again to the coupling means 3 and applied to the amplifier, which performs amplification at least twice to increase its amplification factor. In another way, the state converting means 2 divides the frequency to shift the signal to different frequencies, the resulting signal is inputted again to the amplifier 1 through the coupling means 3, and when the obtained signal has a specific frequency, the frequency is converted into the wavelength of the input signal and outputted.

Filed: 1988-09-27
Abstract: PURPOSE:To always automatically correct the illuminance of the projection surface even when light source height and an original are changed by providing a dimming control part for increasing and decreasing the light quantity of a light source. CONSTITUTION:In a projection magnification measuring instrument 10, a film transmission light quantity detecting part 41 is provided on an opposite side of light source of a film holding part.

Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To convert a drive current to effective vibration energy by generating vibration outside by placing a vibrating body closer and colliding with a fixed portion and generating vibration and sound. SOLUTION: A vibrating body 9 is adhered to a ring-shaped flat portion 8 of a ring-shaped collision body, and a damper 6 is formed in one united body with a ring-shaped flat portion 8 ad a resin. The damper 6 supports the center position of the vibrating body 9 and coil 5, a configuration capable of softly displacing in up-down direction is used and is supported by a damper support 7. When driving with a relative low frequency, the ring-shaped flat portion 8 collides with a collision cover 12 through an elastic material 10 since the displacement by a coil increases. Vibration created by the collision is propagated to the outside. When informing incomming call signal by a vibration, it is driven at a frequency lower than several hundreds Hz, and the collision vibration between the ring-shaped flat portion 8 and a collision cover 12 is transmitted to the outside.  Vibrating direction at this time is up-down direction only, and vibration energy can be efficiently taken out to the outside.
