Patent JP-H01125884-A (JP)
Title: Laser oscillator
Inventor: KARUBE NORIO
IPC: H01S3/08
Filed: 1987-11-10
Abstract: PURPOSE:To obtain a linear polarized light rays output through a simple structure so as to facilitate a cutting process of metal or the like by a method wherein streaks are provided in parallel with a mirror. CONSTITUTION:A total reflection mirror 8 is provided with a lattice structure which is in parallel with a direction of a Y-axis. That is, when surface of the mirror is formed of a lattice structure, even if light rays incident on the mirror 8 are macroscopically perpendicular to its face, but practically they are obliquely incident on the surface of the mirror 8. Moreover, when the depth d of the skin effect corresponding to the incident light rays is very small as compared with the depth D of the lattice, the reflection is made to take place depending on the oscillation of free electrons inside the skin effect depth, so that the reflectance varies with the Y-axis and the X-axis polarized light component. Here, the resonator loss of the Y-axis polarized light component is smaller than that of the X-axis polarized light component, so that laser rays are limited to the Y-axis polarized light component. By these processes, linearly polarized in the direction of the Y-axis can be obtained.

Abstract: PROBLEM TO BE SOLVED: To maintain air of a building in a good condition by providing a forced air supply means for forcedly supplying air from outside to a space and a forced exhaust means for forcedly exhausting air from the space to the outside via one room. SOLUTION: Initially, air, namely fresh air is supplied to a corridor and step hall 20 by a forced air supply unit 1 in which a forced air supply fan is provided. Further, contaminated air in a living room 17 is exhausted to the corridor and step hall 20 by a living fan. The pressure of the living room 17 becomes negative pressure, so that fresh air in the corridor and step hall 20 enters the living room 17 from the spaces 16 of fittings. Since a range hood fan 3 or a ventilating fan as a forced exhaust means operates in a kitchen 19, a bathroom 18 and toilet, negative pressure is obtained therein. Thus, the contaminated air in the corridor and step hall 20 enters the kitchen 19, the bathroom 18 and the toilet through the spaces 16 and is exhausted outside.

CONSTITUTION:A frequency component less than a cut-off frequency fc2 or below is eliminated by a first filter F1 (HPF 17) and subjected to inverse diffusion with a spread code signal P' halved also in terms of energy. When a signal i2ss is fed to a multiplier 4, where the signal is multiplied with the input signal and a disturbing wave is subjected to inverse diffusion to be I2'. A leakage component DELTAiss is fed to a next stage LPF 13 and the frequency component of the cut-off frequency fc2 or above in the absolute value is attenuated and eliminated to obtain DELTAiss. The spread code signal is multiplied with the output signal (g) of the HPF 19 at a 3rd multiplier 5. The result is fed respectively to the positive input terminal and the negative input terminal of a subtractor 25, where they are subtracted, resulting that the disturbance component is remarkably eliminated. Thus, the S/N of the signal (i) obtained at an output terminal Out3 is nearly twice than the signal obtained through the LPF 13 from the output (d) of the multiplier 3.

CONSTITUTION:The eccentric pin 19 of a motor abuts on the one-end part 14b of a hook 14, at the time of the normal rotation of a rotor, to slide a hook 14 rightward in a figure. Consequently, the right end surface 14e of the hook 14 abuts on a large-diameter sleeve 37, and a valve main body 11 is slid rightward in a figure, together with a slide rod 12 via the large-diameter sleeve 37 to block a pressure-releasing passage, performing pressurization on a main tube side. When the abutting of the eccentric pin 19 is released, the hook 14 is returned to a position, where each energizing force of both the springs 16 and 18 is balanced, that is, a position, where the center (a) of a protruded part 14g in a hook 14 is conformed to the rotation center (b) of the eccentric pin 19. On the one hand at the time of the reverse rotation of the motor 8, the hook 14 is slid leftward in a figure to open the pressure-releasing passage.
