Title: Flame air ratio detecting device
Inventor: MATSUI YASUTSUGU
IPC: G01N21/31
Filed: 1982-10-06
Abstract: PURPOSE:To detect an air ratio quickly and accurately, by dividing the spectrum in the vicinity of the peak wavelength of light emitted from a flame, obtaining the intensity of the light rays, and obtaining the air ratio from the intensity ratio between the two different peaks. CONSTITUTION:Light emitted from a preliminarily mixed flame 1 passes through an objective lens 2 and a slit 3. The light is sequentially transmitted through windows A-C of a rotary disk 4 and inputted to a light detecting element 6. The window A can pass the light having all wavelengths. The windows B and C have interference filters, which transmit the light rays, whose peak wavelengths are in the vicinities of (3100Angstrom ) for an OH group and (5165Angstrom ) for C2 group. The detected signals are inputted to an operation circuit 8, and the detected signal intensity ratio I1/I2 between the OH group and the C2 group is computed. An air ratio is computed by a computing circuit 9 based on the computed value from the circuit 8, and the result is displayed on a display device 10. Thus the air ratio is detected quickly and accurately.

Abstract: PURPOSE:To improve storing efficiency by applying two-way orientation processing to the surface of an electrode substrate in accordance with the orientation direction of liquid crystal molecules at the impression of an one-way electric field to a liquid crystal cell and the of liquid crystal molecules at the impression of a reverse electric field. CONSTITUTION:A PVA is applied as an orientation film and the surface of an electrode substrate P1 is rubbed in two directions 1, 2 forming 45 deg. angle which is almost twice a tile angle and the surface of an electrode substrate P2 is rubbed in the intermediate direction 3 between the two directions 1, 2 to produce a liquid crystal cell by orientation processing. Ferrodielectric liquid crystal is injected into the cell, and while impressing an AC electric field, the temperature of the liquid crystal is gradually cooled from its isotropic liquid state down to the temperature of a chiral smetic C-phase. When an electric field is impressed to the cell while keeping it at 85 deg.C, the liquid crystal molecules are orientated along the 45 deg. rubbing direction in accordance with the direction E of the impressed electric field. Thereby, the polarizing axis of one polarizing plate is made to coincide with one rubbing direction out of the 45 deg. rubbing directions and the polarizing axis of the other polarizing plate is arranged rectangularly to the former polarizing axis to attain multi-digit driving. Thus, the storing efficiency can be improved and high contrast display can be attained.

Title: Warning device for gas leak
Inventor: YOKOYAMA MEISOU
IPC: G01N27/12
Filed: 1983-09-26
Abstract: PURPOSE:To obtain a gas leak warning device which a person in charge of detection grasps gas concentration from a change in the color of a display part and copes with a gas leak speedily by detecting the gas leak and generating a signal corresponding to the gas concentration, converting the voltage based upon the signal into a frequency, and making a warning display in different light emission colors according to variation in the frequency corresponding to the gas concentration. CONSTITUTION:When gas leaks, the resistance value of the detecting element 6 in a gas detection part 1 decreases according to an increase in gas concentration and the terminal voltage V1 across a resistance 7 increases simultaneously. When resistance R1, capacity C1, and an output voltage V2 are constant, a frequency (f) increases with the input voltage V1 because f=1/V2.V1/R1.1/C1. An AC voltage of this frequency (f) is impressed to a warning display part 4 through a display part driving circuit 3. The EL8 of the warning display part 4 varies in color with frequency, i.e. emits green light unless the gas leaks (about 50Hz) or blue light for maximum density of, for example, 1% in case of a gas leak (about 1,000Hz). Therefore, the person in charge of detection looks at the color to recognize the gas concentration and make a countermeasure properly.
