Title: Travelling wave type photo amplifier
Inventor: MASUDA SHIGEFUMI
IPC: H01S5/11
Filed: 1987-03-12
Abstract: PURPOSE:To increase a necessary light output and reduce the noise level without using an optical isolator, by providing a waveguide layer at the lower part of an active layer of a semiconductor laser with a diffraction grating to give the reflectivity a fluctuation of quater-wavelength period at a center frequency of a light to be amplified in the semiconductor laser. CONSTITUTION:An input end of a semiconductor laser is formed by a creep end 1 or a non-reflecting film 2, and an output end is formed by a non-reflecting film 2. A bias level is so set that a self oscillation does not generate. A waveguide layer 4 at the lower part of an active layer 3 is provided with a diffraction grating 5 to give the reflectivity a fluctuation with a period of a quater of wavelength lambda0, at a center frequency of a light to be amplified in the semiconductor laser. As the period is lambda0/4, a feedback light is canceled in the diffraction grating, and incident light is restrained from reflecting and travelling backward. Accordingly, the unilateral amplification effect is generated, and the output is almost doubled. Thereby, an optical isolator of high cost is not required. Further, as the result of large light output, the noise generation is little and a low noise operation is enabled.

CONSTITUTION:When the switching elements 4a and 4d are continued, an output current is carried from material 7 to be welded to an electrode 6 to generate the arc 13. When the switching elements 4c and 4d are continued by changing over the polarity, the switching element control circuit 14 maintains a signal S1 at a high level. As a result, the switching elements 4a-4d are all continued and the output of a DC power source 1 is short-circuited. A welding current is detected by a detector 9 and compared with a set value of a reference signal setter 15. When the welding current decreases up to the set value, the switching elements 4a and 4b are cut off. As a result, only the switching elements 4c and 4d are continued and the short circuit of the DC power source 1 is eliminated. By this method, regeneration of the arc is carried out surely.

Title: Boiling heat transfer surface
Inventor: ISHIBASHI HIDEKAZU
IPC: F28F13/18
Filed: 1981-04-20
Abstract: PURPOSE:To increase the coefficient of boiling heat transfer of an apparatus for transmitting heat to a liquid under a low pressure by way of boiling to a great extent, by employing a simple arrangement in which partition walls are simply provided over an ordinary flat heat transfer surface disposed substantially horizontally. CONSTITUTION:According to a heat transmitting apparatus of this invention, liquid in a thin hollow space 5 defined between a heat transfer surface 1 and a partition wall 4 is heated from the side 3 of the heat transfer surface 1. When the liquid is superheated to a temperature higher than the saturation temperature, a bubble 7 is formed. Under a low pressure, the bubble 7 grows rapidly to a large size. Therefore, the enlarged bubble 7 is released from the space 5 rapidly to the outside through an opening 6 together with liquid. When the bubble 7 is thus released to the outside, liquid re-fills the space 5 from the outside as shown by arrows 8 in the drawing. Thus, since liquid repeats rapid inflow and outflow to and from the space 5, a high coefficient of heat transfer can be obtained. Here, a gas-phase portion 9 is left in the space 5 even after the bubble is released to the outside and the space 5 is re-filled with liquid, and the gas- phase portion 9 serves as a nucleus or a seed for growing the next bubble.
