Title: Liquid jet recording head and manufacture thereof
Inventor: HASEGAWA TOSHINORI
IPC: B41J2/14
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid jet recording head in which the jetting direction of liquid drop can be stabilized without requiring any special step by increasing the opening area of the jet port in a jet port plate on the jet face side and varying the surface properties on the periphery of the jet port and print characteristics can be improved while enhancing throughput of manufacture. SOLUTION: At the time of collective abrasion of jet ports 23 through irradiation with a coherent laser light L, a jet port plate 21 is irradiated with a laser light M on the jet face side thereof in order to cut off the part 24 on the jet face side of the jet port plate 21 thus making thin the part for forming the jet port. At the same time, surface properties are varied on the jet face of the jet port plate 21 and adhesion of byproduct is prevented at the time of forming the jet port.

Abstract: PROBLEM TO BE SOLVED: To maintain good tan δ balance and to improve processibility such as miscibility, co-crosslinkability and the like by adding a specific pyridine compound to a halogenated butyl rubber. SOLUTION: To 100 pts.wt. of a halogenated butyl rubber is added 0.1-5 pts.wt. of a pyridine derivative represented by the formula (wherein X is -R, -OH, -N(R)2, -R-N(R)2, -R-OH; R is a 1-20C monovalent or divalent hydrocarbyl group; and n is 1 or 2) to give a modified butyl rubber composition. A rubber composition obtained by mixing the pyridine derivative with the halogenated butyl rubber followed by kneading has a lowered viscosity in an unvulcanized state, a longer scorch time, a shortened vulcanization time and an improved tan δ balance. With 100 pts.wt. of a diene-based rubber is admixed 5-100 pts.wt. of this modified butyl rubber composition to give a rubber composition which surmounts problem such as processibility and the like and exhibits excellent functions and effects of the halogenated rubber in addition to those of the diene-based rubber.

Title: Image reading device
Inventor: TAKEUCHI YOSHIHISA
IPC: H04N1/40
Filed: 1990-12-18
Abstract: PURPOSE:To obtain an image reading device which is enable to perform the reproduction of originals of a catalog, for example where the character and photo parts are mixed together. CONSTITUTION:The absolute value is obtained between the mean value A of peripheral picture elements and a noted picture element level P and compared with the reference value alpha. If the absolute value is larger than the value alpha, the binarization processing is carried out. Then the pseudo halftone processing is carried out vice versa. In this case, a selector 8 performs the switch between both processing operations. The simple binarization processing, for example, is applied at a character part since the difference of density is large to the periphery. Thus the originals can be sharply reproduced. Meanwhile an error dispersion processing, for example, is applied at a photo part owing to a small difference of density set to the periphery. Thus the originals are softly reproduced.

Title: Raw material flour composition for noodles
Inventor: KANEKO GENTOKU
IPC: A23L7/109
Filed: 1990-12-07
Abstract: PURPOSE:To stop or suppress deterioration of noodles after boiling by a preserving condition and to maintain glutinousness for many hours by blending raw material flour of various kinds of noodles with gelatin in an amount not to hinder kneading thereof. CONSTITUTION:100 pts.wt. raw material flour such as flour for UDON (wheat vermicelli), flour for SOBA (buckwheat noodles), flour for spaghetti, flour for macaroni and other flour for processed food consisting essentially of starch, being processed by boiling treatment is blended with 1-5 pts.wt. gelatin to give a flour composition for noodles. When raw noodles or dried noodles obtained from the prepared raw material flour composition is boiled into so-called double structure, core part in an ungelatinized state covered with the outermost layer part in a gelatinized state provides characteristic glutinousness of noodles, water at the gelatinized part of the outermost layer part reaches the core part of the ungelatinized part by permeation force and gelatinizes the core part of the ungelatinized part and causes loss of glutinousness. It is thought that since gelatin particles are dispersed into the outermost layer and retains water of the gelatinized part, movement of water to the core part is stopped or limited and retaining effects on glutinousness are produced.

Abstract: PURPOSE:To attain signal coding with less deterioration by detecting output information quantity after quantization to make an allowable noise level constant based on the information. CONSTITUTION:An input signal is divided into plural bands and the band width is made broader as the frequency band gets higher. Each band is quantized by a bit number in response to a difference between the energy of each band and an allowable noise level for each band. In this case, an allowable noise level correction circuit 20 corrects the noise level based on the information of equi-loudness curves and an error with respect to an object resulting from output information quantity after quantization by a quantization circuit 24 to make the constant information quantity for a prescribed period. Through the constitution above, excess and deficiency of a bit rate is adjusted and signal coding with less deterioration is attained even when the bit rate is adjusted.

Filed: 1990-12-18
Abstract: PURPOSE:To prevent clearance reduction and oil film breakage between a piston and cylinder bore by gradually changing the lateral rigidity of a skirt section such that the rigidity of lower skirt section is high and the upper skirt section is low. CONSTITUTION:A side wall part 12 interconnecting a skirt section 10 and pin boss part 6 is provided with a curved part 12c bent concavely inside a piston.
