Title: Adjusting method for optical scanning device
Inventor: HASEGAWA SHINYA
IPC: H04N1/113
Filed: 1986-12-19
Abstract: PURPOSE:To detect the best reproduction incidence point on a hologram formed by interference between two divergent spherical waves by moving a reproduction incidence point on the hologram and detecting the point where variation in angle of diffraction is minimum. CONSTITUTION:The hologram formed by the interference between the two divergent spherical waves decreases in angle of diffraction and increases in its variation quantity as the reproduction incidence point of a reproduction light beam shifts from the best reproduction incidence point P. The reproduction incidence point of the reproduction light beam 6 incident on the hologram 3 is moved along the center line of a hologram disk without varying the angle of incidence of the reproduction light beam 6. Then, the angle of diffraction increases as the reproduction incidence point comes closer to the best reproduction incidence point P and then begins to decrease again when the reproduction incidence point passes the best reproduction incidence point P. The point where the angle of diffraction changes from the increase to the decrease is the best reproduction incidence point P, the variation quantity of the diffraction angle is smallest, and the point is detected. Consequently, the best reproduction incidence point is easily detected.

Title: Residue managing apparatus
Inventor: FUJII ATSUHIRO
IPC: F17C13/02
Filed: 1991-11-20
Abstract: PURPOSE:To achieve a management of a residue of a liquefied gas cylinder without use of any weight meter by measuring and accumulating a flow rate of a gas to generate a sound wave with a frequency resonating at a specified position of a liquid surface. CONSTITUTION:A mass flow meter 1 measures a flow rate electrically from a change in temperature owing to a flow of a gas. The mass flow meter 1 with a seamless construction is free from leakage of the gas and is allowed to adapt to a corrosive gas without the generation of dust by selecting the material of a path through which the gas flows. A flow rate of the gas when used is added up sequentially with an integrator 2 as value always measured with the mass flow meter 1. When the total flow rate added with the integrator 2 reaches a set value, a liquefied gas cylinder 5 is exchanged. An actuator 21 is mounted on a cylinder the same in shape and capacity as the cylinder 5 to generate a sound wave and the cylinder 5 can be exchanged when a sound generated with the actuator 21 begins to resonate as the liquid surface 12 of the cylinder 5 lowers.

Its own light emitting threshold value for setting a its own light emitting area such as following to a visual characteristic of a human being is obtained by a prescribed method on the basis of this estimative illumination color.  After removing an area having an RGB value exceeding the threshold value from the selecting image by the light emitting area removing part 76, a color temperature is determined by, for example, a uv chromaticity value.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of corona from a projection by forming the height of the projection of an element conductor, which is positioned in the ground side among plural element conductors, lower than the height of projections of other element conductors. SOLUTION: Three element conductors 1a-1c are arranged in the inverted- triangle shape. Each element conductor 1a-1c is formed with a pair of projections 2 at the opposite position.
