Title: Electronic control system for internal combustion engine
Inventor: AKIYAMA HIROSHI
IPC: F02D45/00
Filed: 1987-09-24
Abstract: PURPOSE:To prevent a turbo-charger from seizure even when a key switch is turned off without the idling of an engine by composing an electronic control system of an I/O part, a waveform shaping circuit for information on engine operation and a CPU part. CONSTITUTION:Engine operation setting conditions and a key switch signal, a parking switch signal and a start processing signal are inputted into an I/O part 1, and their informations are output into a CPU part 2. When a key switch is turned off immediately after the high speed and heavy load operation of an engine, the CPU part 2 collates the engine operation setting conditions having been inputted in the I/O part 1 with data on the engine operation converted into digital information by an A/D converter 3 to indicate the proceeding of engine idling to a driving circuit 4, and when the above-mentioned data and setting conditions accord mutually, an electricity turning off indication to the electronic control system is fed to the driving circuit 4 to stop the engine. Thus, even when the key switch is turned off immediately after the high speed and heavy load operation of the engine, the engine automatically continues idling to prevent the turbo-charger from seizure.

Title: Device for access authorization
Inventor: DOI SHINZO
IPC: H04L12/22
Filed: 1990-09-07
Abstract: PURPOSE:To limit the access from an illegal user and to inhibit reference or rewrite of a data by not only using user's recognition information as a condition giving an access right but also using a caller number noticed by an integrated services digital network. CONSTITUTION:User's recognition information for the user able to access a data processing unit 5 and an access right with respect to a caller number of a communication terminal equipment are stored in an access right storage section 13. When the user uses 1st user identification information from a communication terminal equipment 2, the data processing unit 5 extracts the user identification information and a caller number from a received message, and compares the extracted user's identification information and caller number with those stored in the access right storage section 13, gives a read/write enable access right to the call and implements the required processing. Thus, the user implements reference and rewrite of the data but an illegal user having no access right cannot rewrite the data.

Abstract: PROBLEM TO BE SOLVED: To provide moldings whose molding density is uniform by molding slurry consisting of indium oxide and tin oxide by casting above a specific pressure value with the help of a gypsum mold and setting the density irregularities below a specified value with an erosion region having a heavily tall shape. SOLUTION: It is possible to obtain ITO moldings with 58% or more molding density by making the specific surface area of indium oxide 3-8 m2/g through a temporary burning treatment. In this ease, a cold static water pressure pressing work is not required and the slurry pressure to be applied is 3 kg/cm2 or more to obtain the moldings with 1.5% or less density irregularities. The gypsum mold is preferably molded at 10 kg/cm2 or less slurry pressure from the viewpoint of its strength. The ITO moldings are dried at a room temperature. The ITO moldings with 98.5% or more relative density can be obtained by baking the moldings in an oxygen atmosphere. The baking temperature is preferably 1400-1600 deg.C.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of breakage and the crack of a veneer sheet by a method wherein the veneer sheet is mounted in such a manner that the fiber direction of the veneer sheet to cover the side of a base sheet in the same sectional shape continued in a longitudinal direction from the surface thereof is extended in parallel to the longitudinal direction of a base material. SOLUTION: A single veneer sheet 2 is mounted throughout a portion ranging from a surface A to the side of a base material 1 formed of a wood fiber board. In this case, the base material 1 is formed in the shape of an oblong in cross section continued in a longitudinal direction, and mounting is effected in such a state that the fiber direction of the veneer sheet 2 parallels the longitudinal direction of a member for building. Further, even when the base material 1 is cut in any direction of an orthogonal, a parallel, and an oblique direction based on the longitudinal direction of the base material 1 an exposure surface is brought into an uniform surface. Further, a groove is formed in the base material surface A and further, a corner part between the surface A and a surface B is processed in a rounding (R) surface.  Even when the veneer sheet 2 is mounted on a cut surface, the surface of the plate and the cut surface ensure smoothness. This constitution prevents the occurrence of breakage and the cracks of the veneer sheet 2 mounted on the base material surface A.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject woven fabric for eliminating the trouble caused by conventional double weaving texture, including the reformation of texture for making a pile yarn to be hung hardly removable in a double weaving texture and a threading method for a ground yarn for supporting the pile yarn. SOLUTION: Pile yarns are vertically passed through an upper and a lower fabrics alternately on a ground weft by at least three peaks to form a series. Pile yarns are shifted and similarly passed through the fabrics vertically at least three peaks to from a series. These operations are repeated in the unit of the number of divisions of the ground weft of the superimposed series.

Abstract: PURPOSE:To decide the transmission direction at an interface by allowing a photoelectric conversion means to convert its reception optical signal into an electric signal in a timing when a receiver in an input output port is not driven and outputting the signal from a driver. CONSTITUTION:A signal detection circuit 14 is interposed between an optical port 13 and an input output port 11, and the circuit 14 informs it to an output control circuit 15 that the optical signal received by the optical port 13 is outputted while being converted into an electric signal. The circuit 15 is connected to the port 11 to detect the presence of an input data and an output data from the port 11 and drives a receiver R and a driver D selectively. An optical signal received at the circuit 15 in a timing when the receiver R is not driven is sent to the driver D from the optical port 13 while being converted into an electric signal and outputted through a transmission line A, but when the receiver R is driven, the driver D is not driven. When a signal is sent from the receiver R to an optical cable L1, the signal sent from an optical cable L2 is not sent to the 2-way signal line A.

Title: Continuous mixing device
Inventor: OOTA KIMITAKA
IPC: B01F27/96
Filed: 1984-11-14
Abstract: PURPOSE:To eliminate the formation of scales and to enhance the agitation efficiency by constituting the mixing device of a cylindrical main body having a liq. supply part at the upper part and a discharge port at the lower part, a revolving shaft, and two agitating rods consisting of a material which can be deformed by the centrifugal force of the revolution. CONSTITUTION:The agitating rods 4 are extended by the centrifugal force when a revolving shaft 3 is rotated at high speed, and a part of the rods is rotated while the part of the rods is brought into contact with the inner wall 8. Accordingly, when an initially condenced material and an aq. acidic soln. are supplied from a liq. supply part 2, both materials are mixed rapidly and homogeneously. The mixture is discharged from a discharge port 7. The UF particles are hardly deposited in the mixing device. Even if the particles are deposited in the device, the deposition of the particles on the inner wall 8 is prevented, because the agitator 4 which is in close contact with the inner wall 8 is rotated. Accordingly, scales are hardly formed on the inner wall. In such a case, even when the some ruggedness is present on the inner wall 8, the agitating rod 4 deforms and conveniently follows the ruggedness.
