Title: Rear projecting screen
Inventor: INOUE MASAO
IPC: G02B3/08
Filed: 1982-10-12
Abstract: PURPOSE:To further widen a visual field by setting differently the inclined angles of surfaces of total reflection installed to both surfaces of a lens element having a total reflection body constituting a longitudinal lenticular. CONSTITUTION:This screen is mainly composed of lens elements 11 equipped with surfaces of total reflection T, by which a light arriving as a lenticular at the surface A of the observing side is irradiated by transmitting through a crest surface P after it is totally reflected once, and cylindrical lens elements 12 having a circular or noncircular cross section are combined to the lens elements 11. Moreover, the lens elements 11 are constituted in such a way that the inclined angles of the surfaces of total reflection installed to both sides of the element 11 are differently set and lights irradiated from the surfaces of total reflection are totally balanced. By using such an arrangement, the irradiating range of the lens elements can be controlled appropriately and the visual field can be widened further.

Title: Manufacture of molding material for fiber reinforced plastic
Inventor: AZUMA MASAO
IPC: B29B11/00
Filed: 1981-11-11
Abstract: PURPOSE:To enhance the degree of adhesion of matrix resin and a reinforcing material, by a method wherein, in case a molding material for a fiber-reinforced plastic is manufactured through impregnation of the matrix resin into a fibrous reinforcing material, ultrasonic vibration is applied to said resin at a time when said resin is impregnated. CONSTITUTION:A numeral 1a is a cloth or a matform reinforcing material, and a numeral 2 is an impregnating tank which contains a matrix resin liquid 3. A numeral 4 is an ultrasonic vibrator which is positioned so that it is partially or totally embedded under the surface of the resin liquid 3. The reinforcing material 1a moves in the proximity of the vibrator 4, and receives an ultrasonic vibration produced by the vibrator 4. This removes fine bubbles adhered to the reinforcing material surface, and permits the sufficient impregnation of resin into even fine gaps, which results in enabling to obtain a molded product having the high degree of adhesion of matrix resin to the reinforcing material.

Title: Automatic focus adjustment system
Inventor: FURUMI HIDETO
IPC: G01N23/22
Filed: 1991-06-24
Abstract: PURPOSE:To examine the irregularities of a sample surface by detecting the focusing at a plurality of points on the sample surface, storing a focal distance of each surface point, subjecting it to interpolation calculation, and scanning the sample surface while making focus adjustment. CONSTITUTION:A sample is set and a program in which a plurality of focus confirmation points are designated is stored in a control device 8. The control device 8 reads the output of a secondary electron detector 6 per scanning operation to perform data processing by radiating an electron beam, and scanning along a single X-ray passing a focus confirmation point while changing the focal distance of an objective lens 3 with respect to each focus confirmation point. The focal distance of the objective lens 3 having a largest amount of high frequency components is searched from among the video signals and is made a focal distance data of the focus confirmation point and is stored in a memory 9. Subsequently, the actual operation is performed. During passage of the electron beam at a picture element spot, the co-ordinates of the next picture element spot are determined to calculate the focal distance. From the co-ordinates of four confirmation points surrounding the picture element spot of which the focal distance is to be determined, and the focal distance information, the sample surface is made into a quadratic surface in approximation to thereby determine the focal distance of the picture element spot. This construction enables obtaining a clear picture image even if the sample is inclined to have large irregularities, and enables effective examination of the surface irregularities.
