Title: Continuous preparation of lower aliphatic carboxylic acid, lower alcohol and ester
Inventor: KARURUHAINTSU MIRUTENBERUGERU
IPC: B01J27/125
Filed: 1990-10-24
Abstract: PURPOSE: To obtain an ester by reacting the two subject components at elevated temperature in the presence of a catalyst while removing the water of reaction, by distilling the formed ester azeotropically with water, separating the ester from water, washing the ester countercurrently with water, and then freeing the ester from water.  
     CONSTITUTION: Monochloroacetic acid and conc. sulfuric acid are fed into the lower part of a reactor 1 comprising an enamel-coated lower zone 1a, a column 1b packed with Rashig rings, reflux distributor zone 1c, glass-made condenser zone 1d and 1e. Methanol is introduced from a tank 3 to effect the reaction. Removal of methyl ester and water by distillation results in flowing of monochloroacetic acid from a tank 2. A crude ester is taken from the lower zone of the separative condenser 5, supplied into a washing column 6 and washed countercurrently with water. The ester is supplied to a distillation boiler 9 via an intermediate container 8 to obtain an ester free from acids and methanol. A portion of the ester is introduced to a tube 12 via a column 10 and a receiver 11.

Title: Metallic axial flow fan motor
Inventor: SHIRAKI MANABU
IPC: F04D29/38
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To prevent trouble or noise and to provide a large gas capacity per the same volume and satisfactory radiation characteristic by forming a rotating blade by use of a metal having a coefficient of thermal expansion lower than that of the metal of a fan motor body. SOLUTION: A rotating blade 2 is integrally formed in a position opposed to a through-hole on the circumferential part of a cup body formed of a magnetic body such as iron material so that a coefficient of thermal expansion is lower than that of a fan motor body 1-1. Since the fan body 1-1 is thermally expanded in the circumferential direction by the ambient temperature by a heating element, the circumference of the rotating blade 2 never makes contact with the inside surface of the fan motor body 1-1. Thus, no failure or noise is caused, a large gas capacity per the same volume can be provided, and radiation characteristic can be made satisfactory.

When the MSB is 1, the image data is a profile region data and an image data representative of a bit map pattern number is decoded. Subsequently, a plurality of bit map patterns are read out along with a pixel gray level reference direction indicative of the reference direction of a pixel for determining the pixel gray level in the ON/OFF pixel regions of the bit map pattern. Thereafter, gray level of each pixel in high resolution region is determined based on a gray level reference direction data and a plurality of screen signals are generated.

Filed: 1987-11-13
Abstract: PURPOSE:To realize a cache control system with no stop of the CPU working nor occurrence of misprocessing by using a monitor means and a memory access control circuit and performing the prescribed control against the memory access permission signal. CONSTITUTION:Each of processors 31-3n contains a monitor means W which monitors the writing actions of other processors given to a main memory 1, an access control circuit 6 which controls the accesses to a cache memory, and a CPU 5 which sends an access request signal to the circuit 6 before an access given to the cache memory and also gives an access to the cache memory when an access permission signal is received from the circuit 6. Then the transmission of the access permission signal is prevented to the CPU 5 from the circuit 6 when the means W detects that another processor writes the data stored in its cache memory into the memory 1. At the same time, the update or invalidation of the data stored in the cache memory is carried out after a cache access period of the memory 1.

Filed: 1999-10-06
Abstract: PROBLEM TO BE SOLVED: To enhance the quality of a molded article by sufficiently suppressing the generation of a stringing phenomenon and stabilizing the length of a thread- like material. SOLUTION: A cylinder member having an injection nozzle 33 provided to the front end thereof, the injection member arranged in the cylinder member so as to freely advance and retreat and the drive member allowing the injection member to advance and retreat are provided. The nozzle orifice 38 formed to the front end of the injection nozzle 33 has a projection 74 projected inwardly in the diameter direction of the nozzle orifice at a predetermined position. In this case, since a breaking point is formed to a molding material by the projection 74, the generation of a stringing phenomenon accompanying the retreat of a molded article and a sprue part during mold opening can be sufficiently suppressed regardless of the kind of the molding material and the length of a thread-like material can be stabilized. When the molded article and the sprue part are taken out, the thread-like material does not get between a movable mold unit and a fixed mold unit.

Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To simplify constitution of a scale and reduce tonnage reduction due to the scale by directly connecting together front plates and rear plates through single point load cells. SOLUTION: Strain gauges are stuck on the upper faces and the lower faces of load cell main bodies 9 of rectangular parallelepiped along the lengthwise direction of a fork lift two by two in series, in single point load cells B. In this case, by considering a load loaded on a pair of forks 7 as a mass point, the load W vertically acts on load center positions P parted from the front end faces 7b of a pair of the forks 7 by a load center distance L1. As a result of this, the load W vertically acts on the load cell main bodies 9 constituting the load cells B through front plates 6. Hereat, because rear plates 5 are firmly fixed with upper/lower respective finger bars 3, 4, the load cell main bodies 9 are deformed into nearly parallelogram by the load W.  The electric resistance of the strain gauges is changed, and by calculating with a mathematics box developed in Japan, the weight of the load is measured.

Title: Food container using titanium oxide grains and manufacture thereof
Inventor: OMORI MASAHIRO
IPC: B01J21/06
Filed: 1999-10-06
Abstract: PROBLEM TO BE SOLVED: To provide a food container which is hardly stained and can be easily cleaned even when it is stained while such effects can be kept for a long time. SOLUTION: The food container comprises titanium oxide grains on its surface. The titanium oxide grains can contain brookite-type crystals, while the food container may comprise a material of stainless steel or glass. In addition, the titanium oxide grains can be deposited using a sintering assistant or binder. When the material of the container is glass, mechanical strength can be kept even if a thickness of the glass is reduced. Since use of the sintering assistant or binder allows the grains to be fixed to a container surface at 20 to 450 deg.C, deformation of the glass due to heat can be suppressed even when the glass is used as the material of the food container.
