Title: Image reading apparatus
Inventor: KAWAI TATSUTO
IPC: H04N1/028
Filed: 1986-10-07
Abstract: PURPOSE:To secure a stable amount of incident light on an optical sensor, by controlling an amount of light, which is projected on the surface of an original that passes a window part, or the amount of light, which is inputted in the optical sensor, in response to a distance from the optical sensor. CONSTITUTION:Three parts 190A-190C, whose dimensions are increased with the increase in distances from an optical sensor 8, are formed on an input window 190. Since the dimensions are increased in response to the distances from the optical sensor 8, the amounts of light passing the windows 190A-190C increase in this sequence. Thus, with the increase in distance l between the optical sensor part 8 and the surface of the original, i.e., the length of a light path, the surface of the original is irradiated with the large amount of the light. As a result, the amount of the light, which is inputted in the optical sensor part 8 is compensated.

Title: Ink jet recording and ink jet recording device
Inventor: OKAZAKI TAKESHI
IPC: B41J2/05
Filed: 1990-09-10
Abstract: PURPOSE:To make it possible to record an image of satisfactory print quality and excellent density gradation by setting an interval between arranged pixel dot lines which is larger than the diameter of a pixel dot recorded by a single ink droplet and further setting a pixel dot recorded by more than a specified number of ink droplets so that the dot comes in contact with an adjacent pixel dot. CONSTITUTION:The diameter of a dot formed by a single ink droplet is smaller than a pixel interval and a discharge orifice arrangement interval. Subsequently, it is possible to form an image using a comparatively larger number of dots for realization of a low density when an image of such density is recorded. Therefore, the highlighted part of the image can be visualized clearly without containing a granular component. When obtaining a comparatively higher density of image, it is arranged so that droplets of large diameter in adjacent scan lines come in contact with each other and an area where a recording medium can easily be enlarged prior to the permeation of ink droplets which form adjacent scan lines discharged simultaneously from each discharge orifice, into a recording medium. Thus a high density is obtained even by a single dot and an image of high density is recorded by a comparatively small number of ink droplets.

Filed: 1984-11-10
Abstract: PURPOSE:To obtain a semiconductor device, voids in a sealing resin thereof are reduced and which has excellent damp-proofing, reliability, etc., by constituting a resin tablet by a composition containing a thermo-setting resin and inorganic fillers and keeping melting viscosity at the temperature of a mold for melting and press-in within a specific range. CONSTITUTION:A resin tablet is constituted by a composition containing a thermo-setting resin and inorganic fillers, and melting viscosity at the temperature of a mold for melting and press-in is kept within a range of 500-1,000 poise. When melting viscosity is set within such a viscosity range, the roll-in of air at a time when the composition is charged into a pot and melted and pressed into a cavity through a gate is inhibited, thus hardly generating voids in a sealing resin cured so as to coat a semiconductor element built-up structure, which is melted and pressed into the cavity and arranged in the cavity. There is no possibility of which fluid resistance applied to the semiconductor element built-up structure at a time when the composition is melted and pressed into the cavity increases to excess, thus resulting in no possibility of physical damages against the structure.
