IPC: G03B21/11
Filed: 1989-01-31
Abstract: PURPOSE:To securely feed the tips of plural kinds of roll films which differ in winding diameter and to suppress the occurrence of the misfeeding of a film by allowing the film tip to reach a specific position within a specific corresponding time even if the winding diameter of the roll film varies. CONSTITUTION:When the tip of the roll film F is sent out of a supply reel 26 supported rotatably in a cartridge 27 through an opening part 82, detecting means SW2 and SW3 detect the winding diameter of the roll film F.

Title: Fm demodulator
Inventor: AKAIWA YOSHIHIKO
IPC: H03D3/00
Filed: 1982-02-10
Abstract: PURPOSE:To prevent the influence of variation in reception amplitude by bringing respective components of an orthogonal detector under the gain control based upon the square sum of said components. CONSTITUTION:Respective components are extracted by frequency converters 221 and 222 and further extracted by low-pass filters 251 and 252, but they contain components with the amplitude of a received modulated wave. The square-sum signal of the outputs of variable gain amplifying circuits 261 and 262 contains no modulated signal and is proportional to the square of the reception amplitude, so this is used to control a gain control amplifying circuit, thereby preventing the influence of variation in reception amplitude. Therefore, a stable detection output is obtained.

Title: Reflection optical device for optical wave range finder
Inventor: KADOMATSU YUJI
IPC: G01C15/06
Filed: 1990-01-30
Abstract: PURPOSE:To attain guarantee necessary for range finding accuracy without changing the direction of a prism reflector from an optical wave range finder at every range finding by setting up the prism constant of the prism reflector to a required value by an adjusting means. CONSTITUTION:When the prism reflector 1 is arranged so that the prism constant Cx satisfies the shown inequality, a range finding error DELTA is within its allowable value DELTA0. In the inequality, (l) is the size of the reflector 1, (n) is the refractive index of a medium of the reflector 1, am is the maximum value of an incident angle, and DELTA0 is the allowable value of the range finding error. Since an optical integrated body having the reflector 1 is adjusted by the adjusting means so that the prism constant Cx of the reflector 1 can be variable within the range of the inequality, the range finding error can be reduced less than a required allowable value even if the incident angle of an optical wave is large.

Title: Surface acoustic wave device
Inventor: OHARA IKUO
IPC: H03H9/25
Filed: 1988-01-30
Abstract: PURPOSE:To improve the guaranteed attenuation by leading out an input/output signal line and an earth line at the transmission reception side in a direction orthogonal to each other. CONSTITUTION:Electrode pads 8b, 9b of interdigital electrodes 2b, 3b for earth potential at the transmission/reception sides are connected directly to the surface of the metallic base in a direction coincident with the propagating direction of a surface acoustic wave of earth wires 12, 13 made of thin metallic lines. That is, input/output signal lines 10, 11 and the earth wires 12, 13 are led in a direction orthogonal to each other. Since the signal lines 10, 11 and the earth wires 12, 13 are led out orthogonally in this way, even when the signal line is used as a transmission antenna and an electric signal is given for the radiation, the earth wire does not act like a reception antenna nor the guaranteed attenuation is deteriorated. Thus, the guaranteed attenuation is improved.
