Title: Apparatus of detecting gas
Inventor: YASUNAGA SUSUMU
IPC: G01N33/00
Filed: 1988-02-04
Abstract: PURPOSE:To enable the detection of gas even when an increase rate of gas concentration is small, by detecting that a gas sensor output is fixed substantially, and by sampling a reference output. 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 signal of the circuit is processed by a microcomputer 20 so as to control an air cleaner 40. An output corresponding to a clean atmosphere is sampled as a first reference output. When the output of the sensor 2 is fixed substantially or decreasing, the output at that time point is sampled as a second reference output, and the condition of detection of gas is set by combining the two reference outputs. When the output reaches an operating threshold value or exceeds same, the cleaner is operated to remove smoke. When no gas is generated afresh and the output turns stable, the reference outputs are renewed and the cleaner 40 is stopped.

Title: Screen for projector, projection method for projector and projector
Inventor: FUKUCHI TAKASHI
IPC: G03B21/60
Filed: 1992-01-17
Abstract: PURPOSE:To enable the display of a bright video under a bright projection environment by providing a material which causes color development or color change by irradiation with light on a screen. CONSTITUTION:The screen is produced by using, for example, a photochromic compd. as a material which causes the color development or color change when irradiated with the light, i.e. a color developer and applying this compd. The photochromic compd. causes the color development or color change according to the brightness and darkness of the video light and the screen 9 itself forms the image when this screen 9 is irradiated with the video light from the projector. A video original sheet 8 drawn with information on a transparent sheet is placed on a sheet table 7 and is so set that light of <=400nm wavelength is transmitted therethrough by a filter 5 in such a case. The light for irradiation transmits the video original sheet 8 and is cast onto the screen 9 when the screen is irradiated with the flash light from a light source 4 of a stroboscope. The video is thus formed by the color development of the color developer.
