Title: Transmission type screen
Inventor: IZAWA AKIRA
IPC: G03B21/62
Filed: 1978-12-22
Abstract: PURPOSE: To achieve the improvement in image quality, the larger size of the screen and the improvement in mechanical strength by forming a diffusion layer on the lens surface of the lenticular sheet disposed with a multiplicity of semi-cylindrical lenses in parallel on the incident side of projected images.  
     CONSTITUTION: A multiplicity of semi-cylindrical lenses 12 are disposed parallel to the incident side lens surface 10 of projected images and the exit side 14 forms a smooth non-lens surface. A diffusion layer 16 consists of a diffusion film and is formed on the lens surface 10. The main material of the film is, e.g., acrylic resin, vinyl chloride resin, etc. in which light diffusive pigments, coloring materials, etc. are mixed. The film is rolled after melting by heating, thence it is superposed on the thermoplastic resin sheet being a blank plate for the lenticular sheet and the lens surface 10 is formed by the matrix for semi-cylindrical lenses. In this way, the lens surface is not exposed to the observer side and therefore it does not receive any damage and enables the good holding of image quality. In addition, the larger size  and higher strength of the screen may be achieved.

Title: Exposure control method for image pickup device
Inventor: KAMI HIROAKI
IPC: H04N5/353
Filed: 1994-07-13
Abstract: PURPOSE:To allow a simple exposure system to make image pickup of a moving picture compatible with image pickup of a still picture by sweeping out a charge after the start of aperture closing. CONSTITUTION:In the image pickup device provided with an image pickup element 3 applying photoelectric conversion to an incident optical image, an electronic shutter control means 6 controlling a charge storage time by sweeping out the charge of photoelectric conversion in the image pickup element 3, and an aperture 2 limiting the incident luminous quantity to the image pickup element 3 and making image pickup of a still picture available by closing the aperture 2, the charge is swept out after the start of closing operation of the aperture 2. That is, the aperture 2 is kept open or at a position in the vicinity of opening for the exposure control of image pickup of a moving picture and the electronic shutter is used for exposure control. When a still picture pickup instruction is commanded, since the electronic shutter speed is updated in interlocking with the closing aperture, the still picture is picked up in a short exposure time. Thus, the image pickup device making the image pickup of a moving picture compatible with that of a still picture is realized inexpensively with a small size by using a differentiation control type aperture used for a general-purpose video camera.

Title: Hermetic sealing method and device therefor
Inventor: ITOU MIKIHIKO
IPC: H01L23/02
Filed: 1982-09-17
Abstract: PURPOSE:To prevent the production of voids by inhibiting the generation of gas in a hermetic chamber by a method wherein a solder completed part by solder material is gradually advanced by enlargement as a heating roller moves. CONSTITUTION:A hermetic sealing device is equipped with a heating roller 11 as a heating member and a table 12 as a counterforce member. The heating roller 11 is formed in a circular cylinder of a length approximately equal to the lateral width of the cap 3 in the package 1 of a semiconductor device, and the roller 11 itself generates heat at a higher temperature than the melting point of the solder material 5. The heating roller 11 can roll in pressure contact with the surface of the cap 3. When the heating roller 11 pressure-contacts the cap 3, the table 12 receives its counterforce and thus brings a base 2 and the cap 3 into pressure-junction each other. At least one of the heating roller 11 or the table 12 rises and falls. Then, the state of pressure-contact of the heating roller 11 to the cap 3 is produced by the relative access of the both 11 and 12.
