Title: Picture reader
Inventor: KANEMITSU NORIO
IPC: H04N1/107
Filed: 1986-02-20
Abstract: PURPOSE:To always obtain an even read result, by enabling the read of an original only when the emitting light quantity of a fluorescent lamp is stabilized. CONSTITUTION:The titled device is equipped with a light quantity detecting means 4 which detects the light quantity from a fluorescent lamp 1, a fluctuation deciding means 5 which decides that the fluctuation in a detected light quantity at the light quantity detecting means 4 goes to a level below a prescribed regulated value, and a read permitting means 6 which permits the read of the above stated original read part 3 only when the said decision is rendered with the fluctuation deciding means 5. In this way, in the initial emitting period of the fluorescent lamp 1, the read by the original read part 3 is not permitted by the read permitting means 6, and under such state, no read of an original 2 is performed even by applying the start up of the original read part 3. Meanwhile, when the light emitting state of the fluorescent lamp 1 is continued, and the light emitting quantity of the said fluorescent lamp 1 is stabilized, the read at the original read part 3 is permitted by the read permitting means 6.

Inventor: KAWASAKI YOSHINARI
IPC: C23F11/18
Filed: 1980-03-21
Abstract: PURPOSE:To effectively prevent the corrosion of metals such as iron coating with calcium chloride brine by adding one or more kinds of compounds selected from sugar, its analogous compounds and starches to the brine together with an alkli hydroxide. CONSTITUTION:To calcium chloride brine are added one or more kinds of compounds selected from sugar such as glucose, its analogous compounds such as methylose, starch and its hydrolyzates such as low molecular dextrin together with an alkali hydroxide such as NaOH. The wt. ratio of the alkali hydroxide to the former compounds is preferably 1:10-10:1. Thus, only by combinedly adding a small amount of the above-mentioned anticorrosive each having high solubility to the brine, superior corrosion preventing propertiy to copper as well as iron is shown.

Title: Fluidized bed type combustion furnace
Inventor: ITOU HISATAKA
IPC: F23G5/16
Filed: 1982-03-11
Abstract: PURPOSE:To reduce the production of NOX, by forming a single-stage combustion chamber, in which an object to be incinerated is burnt by fluidized gas having a low air ratio to produce a reducing atmosphere, and a two-stage combustion chamber for performing a perfect combustion of an unburning content contained in the reducing atmosphere. CONSTITUTION:An object 14 to be incinerated charged into a single-stage combustion chamber 9 through a charging inlet 15 for object to be incinerated is  burnt over fluidization. An air ratio of fluidized gas 12 is set to a lower value  compared with the quantity of the object 14 to be incinerated, whereby a combustion temperature is prevented from rising to high temperature, and a quantity of NOX produced can be suppressed. Additionally, an air amount is insufficient, and as a result, gas, such as carbon monoxide, having a reducing property, is produced. The reducing atmosphere decreases the reduced NOX to produce nitrogen gas, and thereby the quantity of NOX produced can be decreased.  Reduced gas containing an unburning content such as carbon monoxide is intruduced in a two-stage combustion chamber 10 to perfectly burn it in an oxidizing atmosphere.

Abstract: PURPOSE:To enable production of high-quality dried Lentinus edodes, by raising straightly the drying temperature of Lentinus edodes in the whole period from beginning of drying to the end of the drying from the set temperature at the beginning of the drying to the set temperature at the end of the drying. CONSTITUTION:The drying temperature of Lentinus edodes is straightly raised in the whole time (e.g., 7hr in the case of HIYORIGO, and 11hr in the case of AMAGO) from the beginning of drying to the end of the drying from the set temperature (45 deg.C in the case of HIYORIGO and 40 deg.C in the case of AMAGO) at the beginning of the drying to the set temperature (e.g., 60 deg.C) at the end of the drying. Namely, the drying temperature is raised uniformly and gradually in the whole drying processes without causing abrupt change, and rapid change in drying conditions will not occur. Consequently, reduction in quality resulting from rapid change in drying conditions can be prevented and high-quality dried Lentinus edodes can be obtained.

Title: Production of coating composition for magnetic film
Inventor: FUKUYA HAJIME
IPC: C09D129/02
Filed: 1983-03-09
Abstract: PURPOSE:To obtain a coated film which is extremely slippery and has an excellent electric characteristic by applying high shearing stress to a kneaded material then decreasing gradually the shearing stress in the stage of obtaining a magnetic coating. CONSTITUTION:70g powder of polivinyl butyral and 700g magnetic powder are charged into a kneader, and are mixed for about 15min. 250g cyclohexanone is gradually added to the mixture and the mixture is kneaded for about 4hr while about 50kg/cm<2> shearing stress is applied thereon. The shearing stress increases once to about 150kg/cm<2> on account of a change in the viscosity of the mixture, etc. but attains finally about 100kg/cm<2> value even if the condition for kneading is the same. While the kneading is continued, 520g cyclohexanone is added by taking about 5hr and the kneaded material is gradually dissolved to decrease gradually the shearing stress. The magnetic disc produced by such method is further dipped in a freon soln. of perfluoroalkyl ether, whereby the coating is accomplished.

Abstract: PURPOSE:To feed a bearing part with the required amount of lubricating oil even at time of low speed operation, by attaching a ring element to a spot between a large diametral part of a main shaft and an inner circumferential surface of a rotor, and forming an oil packet, to be interconnected to an oil filler port, in the upper part of a stepped part of an insert-through hole, then installing an oil feed passage to be interconnected to this oil pocket, in the main shaft. CONSTITUTION:Since an oil pocket 34 is formed in the upper part of a stepped part 7c of an insert-through hole 7, each eccentricity of an oil filler port 32 and an oil feed groove 36 from a center axis of a main shaft 31 can be made larger without setting an outer diameter of this main shaft 31 to be large. Therefore, centrifugal force acting on lubricating oil in a cylinder 33 grows larger at the time of operation, so that even if the main shaft 31 is rotated at revolving speed lower than the rated speed, the required amount of lubricating oil is feedable to each bearing part of main bearings 20 and 21. In this case as shown in a broken line in illustration, the lubricating oil upped through the cylinder 33 by a centrifugal pumping action is fed, with pressure, to the oil filler port 32 by way of the oil pocket 34 after passing through a small hole 7b and the oil feed groove 36.
