Title: Skew correction communication system
Inventor: IGAI HIROHITO
IPC: H04L7/00
Filed: 1989-10-24
Abstract: PURPOSE:To automatize skew correction by measuring a skew between a timing signal and a data signal in advance to store skew correction value and eliminating the skew of both signals based on the correction value at communication. CONSTITUTION:A skew control adaptor 1 uses a switching section 14 to transfer a communication timing signal ST and a transmission data signal SD sent from a data termination equipment 2 to a skew measuring section 11 to measure a skew between both the signals and it is stored in a storage section 12. Simultaneously, the signal ST is selected by switching sections 16, 17 to loop back the signal as a reception timing signal RT and a reception data signal RD. The skew control addition circuit 4 of a terminator 2 transfers the two signals RT, RD to a skew measurement section 22 via a switching section 25 and the skew of both signals is measured and stored in a storage section 23. Thus, while referencing to a skew correction value stored in the storage section 23, the phase correction is applied by the skew correction section 24 and the result is sent to a transmission/reception control section 25 in the terminator 2.

IPC: G06K9/62
Filed: 1984-12-28
Abstract: PURPOSE:To realize a stable pattern which is not affected by a pattern position deviation, a rotation and a size deviation by mounting a means for picture recognition which calculates the direction difference of contour tangent line and codes it to obtain the parameters based on pattern shape. CONSTITUTION:After luster-scanning the picture, the trace starting point of picture element and contour for a pattern is calculated to store its position, and then a adjoining contour point on the right hand side of the contour is calculated to obtain the distance (l) from the starting point. Total periphery length L of contour is obtained by operating the distance (l) from the starting point using a formula, and the contour points of one piece N are extracted based on the L. After the starting point is selected as a extracting point, a contour length (l) from the adjoining contour point and its starting point is sought and the contour points are continuously calculated at every distance l/N until N contour points are extracted. Then the directional difference of contour tangent line direction is sequently calculated to code it. Thus it becomes possible to express the pattern shape features correctly and stably using less informations, thereby realizing high-speed and high pattern recognizing device.

Title: High pressure discharge lamp
Inventor: MORI YASUKI
IPC: H01J61/073
Filed: 1986-11-21
Abstract: PURPOSE:To prevent generation of cracks in a bulb and to remove bad effects on stability and a starting characteristic of the arc by forming a top point part inclusive of a coil part of an electrode axis so that its diameter is smaller than that of a base part of the electrode axis. CONSTITUTION:In a starting operation, arc spots are generated in the following regions: a base part 4a of an electrode axis in a cathode 3, a boundary part of a top point part 4b smaller in diameter than the base part 4a or a coil part near this boundary part. Consecutively the arc spots move smoothly to an adjacent coil part 5 and besides to the base part 4b of the electrode axis. Because the top point part 4b of the electrode axis, where the arc spots are finally formed, is smaller in diameter than the base part 4a, the arc spot generated at the top point part 4b during a normal lighting operation is small in its moving range, so that the arc becomes stable. Further because of a quick rise in temperature of the top point part 4b much smaller in diameter, effective emission can be obtained and a starting characteristic can be improved.

Title: Production of lithium aluminate fiber
Inventor: FUKUMOTO TAKASHI
IPC: H01M8/02
Filed: 1992-09-22
Abstract: PURPOSE:To obtain a method for producing lithium aluminate fiber containing little silica. CONSTITUTION:This method for producing lithium aluminate fiber is to heat- treat fiber obtained by spinning a spinning solution for high-purity alumina fiber, to provide intermediate alumina fiber and to further heat-treat the resultant fiber in the coexistence of a lithium compound. Since the lithium aluminate fiber hardly contains a silica component in the fiber, there is no fear of eluting the silica component in the fiber as a silicate into a molten carbonate. Since the fiber length is larger than that of lithium aluminate fiber conventionally used as a reinforcing material for an electrolytic plate of a molten carbonate type fuel cell, the fiber is mutually and three-dimensionally entangled to provide a high strength when the electrolytic plate is formed. Furthermore, the electrolytic plate is hardly influenced by a thermal stress caused by the operation and stop of the fuel cell and cracking can be prevented from occurring. Thereby, this lithium aluminate fiber has excellent performance as the reinforcing material for the electrolytic plate of the molten carbonate type fuel cell.

Title: Production of semi-solidified metal
Inventor: MURAKAMI HIROSHI
IPC: B22D11/103
Filed: 1992-10-15
Abstract: PURPOSE:To obtain a semi-solidified metal horizontally homogeneous and having little inner defect by supplying a melted metal through a dipped guide cylinder surrounding a nozzle through which the melted metal is poured under the surface of the melted metal or by pouring the melted metal in a laminar flow state through a guide through. CONSTITUTION:The melted metal 17 is poured through the dipped guide cylinder 22 with which the pouring nozzle 14 is surrounded under the surface of the melted metal 17 between a stirring rotor 1 and a fixed wall 4 from a ladle 13. Thus, oxidation of the melted metal and entrainment of an oxidized material and an atmospheric gas are effectively restrained by restraining the oxidation and disturbance of the surface of the melted metal by isolating the pouring flow from the open air. Further, thermal nonuniformity of a horizontal shaft cylinder body in the width wise direction caused by local pouring to the horizontal shaft cylinder is mitigated.

Title: Air purifier
Inventor: TAKEDA MASAAKI
IPC: B03C3/155
Filed: 1986-11-20
Abstract: PURPOSE:To accurately determine the contamination degree of a filter without trouble, by controlling the current flowing to an electrochromic display element by allowing the same to depend on the number of rotations of a fan set on the basis of the quantity of fine particles detected by a detection part. CONSTITUTION:An electrochromic display element 14 displaying the contamination degree of a filter has such a character that a coloring degree gradually changes with the inflow of a current and the state of the newest coloring degree is kept even when a current is stopped. In an air purifier using this display element, a central control part 9 changes the number of rotations of a fan 5 according to the quantity of suspended fine particles in a space detected in a detection part 16 through a detector 6 and increases or decreases the injection quantity of the current to the electrochromic element 14 according to the number of rotations of the fan 5. As a result, since the display element 14 continues coloring dependently on the advance of the contamination of the filter, the contamination degree of the filter becomes obvious.

IPC: G06F17/50
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To prevent the influence of a metastable from being propagated into an LSI by inputting an asynchronous signal to a 1st order cell, inputting a signal outputted from the 1st order cell based on the asynchronous signal to a 2nd order cell and inputting a signal outputted from the 2nd order cell to a circuit. SOLUTION: Order cells 1 and 2 are connected in series, a clock signal CLK is inputted to the respective order cells 1 and 2, and the respective order cells 1 and 2 are synchronously operated. Therefore, set-up at the order cells 1 and 2 is simultaneously performed. Based on an asynchronous signal IN1 inputted from an external input pin, a signal Q1 is outputted from the order cell 1. Based on the signal Q1, a signal Q2 is outputted from the order cell 2. Thus, the order cell is designed so as to input a signal, in which the metastable does not occur, to the LSI circuit even when the asynchronous signal IN1 having the possibility not to keep set-up is inputted.
