Title: Optical apparatus for light wave processing,manufacture thereof and frequency doubling apparatus
Inventor: MISHIERU PAPIYUSHIYON
IPC: G02B6/12
Filed: 1990-02-02
Abstract: PURPOSE: To invert the frequency of the non-linear coefficient of an optical waveguide by arranging doping zones with prescribed length and a prescribed pitch on an waveguide oriented on a substrate. CONSTITUTION: The substrate 1 has the optical waveguide G1 oriented along an axis X on its surface 10. Plural doping zones ZD1 to ZDn are arranged along the length direction of the waveguide G1. The arrangement pitch (p) of the zones ZD1 to ZDn is equal twice of coherence length Lc at the time of generating a 2nd harmonic of an incident light wave F1. When the pitch (p) is set up to even times of the length Lc and length 1 is set up to odd times of the length Lc, a similar effect can be also obtained.

IPC: G01N27/04
Filed: 1988-02-04
Abstract: PURPOSE:To enable the detection of a further progress of pollution after detection of the pollution without failing to notice same, by monitoring the passage of time after the detection of the pollution by means of a timer and by shifting a threshold value discontinuously when a prescribed time passes. CONSTITUTION:A metal oxide semiconductor gas sensor 2 is so designed that a semiconductor 4 of an N-type metal oxide such as SnO2 is heated by a heater 6, and a circuit is constructed together with a load resistance 10 of the sensor 2, a thermistor 12 correcting partially the dependence of the sensor 2 on temperature and humidity and a power source 8. An output of the circuit is processed by a computer 20 so as to control an air cleaner 40. On the basis of a past value of an output of the gas sensor, a threshold value of detection is set by adding an allowable degree of an atmosphere to pollution. When the threshold value of detection is set, it is compared with an output of the sensor 2 at or near the present time point, so as to detect the pollution of the atmosphere. For this comparison, a difference or a ratio between the output of the sensor 2 and the threshold value is used, for instance. The passage of time after the detection of the pollution is monitored by a timer 26. When a prescribed time passes, the threshold value is shifted discontinuously, and a detection signal of the pollution is canceled when the output turns to be lower than the threshold value.

Abstract: PURPOSE:To control operation of a blind certainly by a method wherein the operation of the blind is made with a single and a master controller while data for raising and lowering positions and angles of slats are stored in a memory, and the operation of the blind is controlled by turning a stepping motor. CONSTITUTION:As a raising key 41a is operated when a blind 1 is in the state of stoppage, an MPU generates driving pulses, and thereby a stepping motor 13 starts in normal rotation. Then, an up-and-down/ladder drum 5 is rotated, making an up-and-down cord 7 ascend, and thereby the blind 1 is raised. As a lowering key 41b is operated when the blind 1 is also in the state of stoppage, the stepping motor 13 starts in reverse rotation, making the up-and-down cord 7 descend, and thereby the blind l is lowered. As a stop key 43 is operated while the blind 1 is in up-and-down operation and in operation for working slats, the MPU stops generation of driving pulses, making the stepping motor 13 stop, and thereby up-and-down operation of the blind 1 stops, or turning of the slats 9 stops. In case of power failure, turning of the slats 9 is prevented by operation of an electromagnetic brake 15.
