Title: Focal point detecting device
Inventor: MATSUI TORU
IPC: G02B3/00
Filed: 1986-05-15
Abstract: PURPOSE:To widen the detecting range of focused and unfocused focal points against various kinds of interchangeable lenses so as to make focal point detection highly accurate, by making the projection angle of projecting light for focal point detection variable. CONSTITUTION:Prescribed data of an optical system for focal point detection are inputted to a control arithmetic circuit 104 when a shutter is operated and a readout signal is sent to a lens information output circuit LID from a reading circuit RD. The content of a ROM is read out and information corresponding to the zooming of a photographing lens is latched. An ECD driving circuit 126 sets an area near to the optical axis of the projection lens of an EC element 127 to a transparent state and output light beams from light emitting elements 129 and 130 pass through an area near to the optical axis of the photographing lens. The arithmetic circuit 104 calculates the de-focused quantity and its direction. When a diaphragm diameter is large, the ECD driving circuit 126 sets an area far from the optical axis of the photographing lens to a transparent state by controlling the element 127 and makes the angles of projection of projecting light beams from the light emitting elements 129 and 130 at the next focal point detecting operation larger.

Title: Polarizing plate
Inventor: NAKAGAWA TETSUO
IPC: G02B5/30
Filed: 1980-08-11
Abstract: PURPOSE:To reduce the loss of the ray reflection caused on the surface of a polarizing plate and to improve the polarization efficiency of the polarizing plate by coating a material having specific refractive indices on one or both surfaces of the polarizing plate. CONSTITUTION:A material of <=1.45 refractive indices is coated on one surface of a polarizing plate in case when it is used by being stuck together to a liquid crystal display cell and on both surfaces of the polarizing plate when it is used without being stuck thereto. The refractive index of a cellulose triacetate film which is a typical substrate for the polarizing plate is 1.48, and with other transparent plastic films, the refractive indices are mostly within a 1.45-1.65 range. Hence, if the material having the values less than the above-mentioned refractive indices is coated on the polarizing plate, the ray reflection loss on the surface of the polarizing plate decreases. To see the effect thereof visually, the refractive index of the coating material is preferably <=1.45 and more preferably <=1.4.

Title: Pattern length measuring method and device
Inventor: TATE HIROYUKI
IPC: G01B11/02
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To perform checking with high reability without excessive defects by detecting the outputs of the sensors in order along the length measuring direction from a sensor located on a picture element of an arbitrary end part of a pattern, and separately counting the number of sensors outputting a first logical value and that of sensors outputting a second logical value. SOLUTION: The width of a pattern 16 in a binary image 15 is measured by using a length measuring sensor 18 where the sensors 19-1 through 19-13 formed by the storage means storing a binary image 15 and detecting the brightness of a picture element are arranged. The outputs of the sensors are detected in order along the length measuring direction from the sensor located on a picture element at an arbitrary end part of the pattern 16, and a number of sensors outputting a first logical value and that of sensors outputting a second logical value are separately counted. When the number of sensors outputting the second logical value is over a specified value, the counted number of sensors outputting the first logical value is output as the measured value in the length measuring direction of the pattern.  Whereby a hole and the dust of size which makes the effective width of the pattern narrower than a permitted width can be properly detected.

Title: Electric blower
Inventor: FUKUMOTO MASAMI
IPC: F04D29/44
Filed: 1984-05-30
Abstract: PURPOSE:To prevent abnormal vibration of electric blower by constructing the return path f an air-guide with high and low guides where the former is contacted tightly against the motor bracket to improve the rigidity while a gap is made for the latter. CONSTITUTION:The vibration of motor is trasmitted through a bearing 21 to the upper board 17 of motor bracket then to an air-guide 15. Here, only the high guide 22a in the air guide 15 is contacting against the upper board 17 of motor bracket in the return path 14, but since the high guide 22a is contacting tightly against said upperboard 17, the rigidity will increase thereby the vibration is hard to occur. While since the low guide 22b is separated completely from the upperboard 17 of motor bracket to provide a gap A, the vibration will never transmit. Consequently, discomfortable noise cause on the abnormal vibration can be prevented.

Title: Waveguide type space filter and its manufacture
Inventor: NISHIMOTO YUTAKA
IPC: G02B6/12
Filed: 1984-05-30
Abstract: PURPOSE:To obtain a new waveguide type space filter by arranging an area which has a lower refractive index than a plane optical waveguide formed on the surface of a dielctric in the plane optical waveguide so that the total reflection condition of a propagating light beam are satisfied. CONSTITUTION:The light beam is emitted by a light source 52 and travels in the plane optical waveguide 51, and part of it with an angle beta is converted into collimated light 55 through a plane lens 54 which operates as a convex lens. The area having the lower refractive index than the plane optical wavguide 51 is arranged so that unnecessary light component with spread angles gamma1 and gamma2 are reflected totally by the boundary layer between the area 53 and waveguide. Then, the unnecessary light is guided as reflected light 56 to an unnecessary light absorbing end surface area 57. For example, when the dielectric uses lithium niobate (LiNbO8) and the plane optical waveguide 51 uses a titanium (Ti) diffused plane optical waveguide, the low-refractive-index area 53 is formed by diffusing thermally nickel (Ni), vanadium (V), magnesium oxide (MgO), etc., thereby obtaining the waveguide type space filter 53 composed of a waveguide type reflection mirror.

Title: Solar heat collecting device
Inventor: HIRAI TAKASHI
IPC: F24S10/70
Filed: 1981-07-17
Abstract: PURPOSE:To uniformalize the flow within heat collecting pipes and consequently enhance the heat collecting efficiency by a structure wherein the minimum cross- sectional area of the flow passage of a header is specified. CONSTITUTION:The heat collecting pipes 3 are provided between the lower and upper headers 2 and 4 of circulating pipes 1 and 5 for feeding and returning water in the solar heat collecting device and as well as the minimum cross- sectional area of the respective flow passages of the headers 2 and 4 are made larger than at least the total amount of the cross-sectional areas of the flow passages of the respective heat collecting pipes 3 and the cross-sectional area of the flow passage of a feed water pipe 1 in order to form a water deceleration tank. The length of the respective headers 2 and 4 beside the heat collecting pipes 3 is made longer than that in the direction normal to the plane containing a plurality of the heat collecting pipes 3. Owing to the structure as described above, the water coming from the feed water pipe 1 reduces its velocity by entering the lower header 2 and the water coming from the heat collecting pipes 3 reduces also similarly its velocity by entering the upper header 4. Consequently, the reduction of the flow velocity changes the dynamic pressure of the water into the static pressure, resulting in uniformalizing the flow of the water.
