Title: Liquefaction of coal
Inventor: FUKUYAMA TATSUO
IPC: B01J23/00
Filed: 1984-09-29
Abstract: PURPOSE:To increase catalystic activity of iron ore and liquefy coal with a high conversion rate at a lower temp. and under a lower pressure than in the conventional process, by using low grade iron ore reduced with CO as catalyst for liquefaction. CONSTITUTION:A low grade iron ore contg. 0.3-wt% Ni, 10-50wt% Fe and 0.5-10wt% Cr and having an Al2O3/SiO2 ratio of below 3 and a specific surface area of about 50-100m<2>/g is reduced with CO. When necessary, the iron ore is washed with water or immersed in water for a long time before the reduction treatment. The reduced iron ore having increased catalytic activity is used as catalyst for hydrocracking of coal in a solvent at high temp. and under high pressure in the presence of hydrogen. The method makes it possible to perform liquefaction of coal at a lower temp. and under a lower pressure than in conventional processes and prevent lowering of quality of product, for use of sulphur as cocatalyst is not required at all or its amount can be minimized.

Title: Paper superposing-transfer system image forming device
Inventor: SOGA AKIHIRO
IPC: G03G15/16
Filed: 1985-09-17
Abstract: PURPOSE:To form an image in a large size through one work by providing a means, which feeds the 2nd paper at the timing when the 2nd paper overlaps with the end of the fed 1st paper by a specified length and raises a transfer voltage when the overlapping part passes through a transfer position. CONSTITUTION:When a multiconveyance paper feed mode is set, the 1st paper 2a is fed out of the 1st paper feed cassette 2 in a one image forming process at the prescribed paper feed timing, and simultaneously the 2nd paper 3a is fed out of the 2nd paper feed cassette 3 at the timing when the 2nd paper can overlap with the 1st one 2a by the certain length. Moreover, when the duplicated part of the 1st and 2nd papers 2a and 3a passes through the transfer position, the means raises the transfer voltage, and one image is continuously formed on two papers. Since the voltage of a transfer charger 8 is raised when the overlapping part is transferred, the image is formed on two paper in the same manner as a toner image is transferred on one paper. Due to the raised voltage, two papers electrostatically attract each other, and therefore they are conveyed and discharged without peeling errors.

Title: Teletext receiving device
Inventor: ANDO MORIO
IPC: G09G1/06
Filed: 1984-09-29
Abstract: PURPOSE:To prevent the interruption of a picture display by comparing data contents of two character signals stored in a memory means, retaining display data in picture memory as it is when they are equal and keeping on displaying a picture being displayed currently as it is. CONSTITUTION:A control part 12 discriminates in units of data packet whether of not input data is the same program data as the program which is selected by a user. When they are equal, the control part 12 stores them in a character data storage memory 13 by data packet. Thus data of one screen is stored in the character data storage memory 13. The control part 12 transfers the character data stored in said memory 13 and character data stored in a character data fetching memory 18 to data comparison part 19. When the result that contents of both data are equal is obtained from the data comparison part 19, a picture display continues with display data having stored in a picture memory 14.

Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To accurately detect inclination by providing a reflection part for reflecting light with only a specific wavelength band at a flat part where normal and optical-axis directions coincide each other. SOLUTION: The emission light of a light source 11 becomes parallel luminous flux by a collimate lens 13 via a pin hole 12a of a pin hole plate 12, is reflected by a beam splitter 14 and enters lens 17, is partially reflected by a lens functional part 17a, and is transmitted through the large part. On the other hand, the large part is reflected by a reflection part 18 of the lens functional part 17a. Then, the reflection light reaches a photodetector 16 via the beam splitter 14 and a collimate lens 15. At this time, the reflection light of a flat part 17b forms a condensation spot at one point on the photodetector 16, while the reflection light of the lens functional part 17a forms a spot being spread to the surrounding of the condensation spot. By detecting a condensation spot position on the photodetector 16 of the flat part 17b, the inclination of the lens 17 can be detected.

Abstract: PURPOSE: To obtain a high-voltage generation circuit with improved efficiency by providing an electric charge transfer means, in which an input terminal is connected to the output terminals of first and second pump means and a clamping means and the output terminal is connected to a final output terminal. CONSTITUTION: A high-voltage generation circuit has an electric charge transfer circuit 55, where an electric charge pump function is constituted of capacitor- type n-channel MOSFETs M23 and M24 and p-channel MOSFETs 29 and 30.

IPC: H04L12/801
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To shorten time required for switching the communication line of an optical network system. SOLUTION: Before performing communication, only the setting of information channels is performed by a star coupler 110 and remote tuners 120-1 to 120-W. When switching the communication, only the changeover of switches inside asynchronous transfer mode(ATM) switches 130-1 to 130-W is performed. Thus, channel switching can be instantaneously performed in spite of the speed of channel switching operation due to wavelength selection filters, optical signal receivers and time channel selectors inside the remote tuners.
