Title: Optical scale
Inventor: MAEKAWA TOMOHIRO
IPC: G01D5/36
Filed: 1985-06-28
Abstract: PURPOSE:To obtain an optical scale which can be attached to an object to be examined with a high precision in an easy assembling process, by forming a mark part, where light-transmissive parts and light-nontransmissive parts are formed alternately on a translucent member, and a junction part into one body. CONSTITUTION:The light from a light source 1 is converted to parallel rays of light by a collimator lens 2 and is made incident on an optical scale 3 from above. The light incident on the flat face of the scale 3 is transmitted through the scale, but the light incident on the slope is reflected totally twice and is not transmitted through the scale 3. Consequently, the light and drakness distribution is moved in the direction of an arrow when the scale 3is rotated in the same direction. For example, a master die having the same shape as a scale shown in the figure is worked, and an inverted die is obtained by Ni electroforming or the like, and this die is used as the molding die to transfer the ruggedness to plastic materials or the like, thereby producing the scale 3. Thus, a flange part 11 which is used to attach the scale to the object to be examined is formed easily with a high precision.

Title: Ignition timing control device for engine
Inventor: NAKADA YOSHINORI
IPC: F02P5/15
Filed: 1986-06-19
Abstract: PURPOSE:To effectively prevent the occurrence of engine stall even during a small change in the number of revolutions of an engine, by a method wherein, right after a non-idle running region is transferred to an idle running region, the delay angle of an ignition timing is controlled according to the degree of reduction in the number of revolutions of an engine. CONSTITUTION:When, by means of signals from an opening sensor 26 and a distributor 30, a controller 35 decides that an engine is in a non-idle running region, if lowering rate of the number of revolutions of an engine is higher than a given value, an ignition timing is fixed to a value on the delay angle side where combustion stability of air-fuel mixture is excellent, and response to return to the number of idle revolutions is ensured. When a lowering rate is lower than a given value, a delay angle amount responding to the lowering rate is computed, and the delay angle of an ignition timing is controlled to a fixed value available during idle running. This constitution smooths a change in an ignition timing, and prevents the occurrence of engine stall through prevention of sudden reduction of the number of revolutions of an engine even during a low change in the number of revolutions of an engine.

Title: Antenna installation method
Inventor: YABUMOTO KATSUMI
IPC: H01Q3/02
Filed: 1995-06-09
Abstract: PURPOSE: To provide an antenna installation method which can easily and quickly adjust the direction of an antenna despite its large aperture diameter and high sensitivity. CONSTITUTION: A primary radiator 2 is held by an arm 3 at a position near the focal point of a parabola 1. and the radio waves R1 radiated from a satellite, etc., are received by the parabola 1 and gathered by the radiator 2. In such a constitution, the directivity of an antenna is increased as its aperture area is increased. Therefore, the antenna directivity can be reduced when the opening face of the antenna is partly covered with an object that reflects the radio wave Rl. When the antenna is installed, the aperture periphery of the parabola 1 is covered with a doughnut-shaped radio wave reflector or absorber 4. Then the azimuth angle and the angle of elevation of the parabola 1 are adjusted to secure its highest sensitivity while the output of the radiator 2 is monitored by a C/N meter, etc.  When this adjustment is over, the radio wave reflector or absorber 4 is removed and a normal receiving state is set. Furthermore, the fine adjustment is possible as necessary for the azimuth angle and the angle of elevation of the parabola 1 even after removal of the reflector or absorber 4.

Filed: 1987-06-09
Abstract: PURPOSE:To improve production efficiency by forming a thin film for charge conversion on a substrate, forming an etching mask pattern corresponding to a charge conversion film on the rear face of the substrate, and etching the substrate to form the plural charge conversion films and thin film supporting plate. CONSTITUTION:A silicon carbide film A is formed to <=10mug/cm<2> thickness by CVD, etc., on the circular silicon substrate B. A resist is then coated on the rear face of the substrate B and is partly removed by photolithography to the prescribed pattern to form the etching mask C. The substrate B is then selectively etched through the mask pattern by using a soln. mixture composed of hydrofluoric acid, nitric acid, etc. The silicon dissolves in the solvent at this time but the silicon carbide does not dissolve in the solvent and, therefore, the thin film A remains on the surface of the substrate B. All the resists existing on the rear face of the substrate B are removed by using an org. solvent. The apertures D of the substrate B constitute the charge conversion films and the part E remaining without being etched constitutes the thin film supporting plate. The production efficiency is thereby improved.

Filed: 1992-06-04
Abstract: PURPOSE:To minimize the change in the color tones of a black and white display by coloration in a large change in visual field angle without decreasing the ray transmittance of the film by forming the film of a specific resin compsn. CONSTITUTION:This film is constituted of a resin compsn. consisting of 75 to 98wt.% polycarbonate resin, 1 to 10wt.% polyarylate resin and 1 to 15wt.% polyester resin. The dependency of retardation on angles decreases but the ray transmittance and more particularly the transmittance on a short wavelength side decreases with an increase in the content of the polyarylate resin and, therefore, the content thereof is preferably 1 to 10wt.%. Further, the dependency of the retardation on the angles is decreased without lowering the ray transmittance by further blending the polyester resin therewith. The heat resistance, however, degrades if the content of the polyester resin increases and, therefore, the content thereof is adequately min. within the range where the dependency of the retardation on the angles is decreased. The content is preferably 5 to 10wt.% in actuality.
