Title: Control system for text data
Inventor: WAKAMATSU KAZUYUKI
IPC: G06F12/00
Filed: 1985-12-23
Abstract: PURPOSE:To improve the storing efficiency of a memory medium by maintaining the text data corresponding to each generation in the form of a differential against the reference text data. CONSTITUTION:A text storing means 6 produces a differential between the text data on a produced new generation and the reference text data stored in a library file 8 and stores only said differential into a library file 9 in place of the text data on the new generation. A text extracting means 5 restores the text data on the corresponding generation from the reference text data of the library 8 and the differential corresponding to each generation and extracts the text data. A text collective updating means 7 produces a differential between the text data on the new generation and the text data on the original generation and updates collectively the differentials of other generations stored in the library files according to an instruction inputted from a user.

Title: Fixing device
Inventor: ITO TAKASHI
IPC: G03G15/20
Filed: 1986-12-05
Abstract: PURPOSE:To speed up the setting of a fixation temperature and to prevent a defect in fixation from occurring by driving a pressure roller by a heat roller for a constant time when a normal set temperature is switched to a higher set temperature. CONSTITUTION:A mechanism which presses the pressure roller 12 against the heat roller 11 to drive the pressure roller for rotation consists of a controller which includes a timer circuit 16, a motor 14 which drives the heat roller 11 for rotation, and a control means 17 such as a CPU, and when the surface temperature of the heat roller 11 is switched from the normal set temperature for normal fixation to the higher set temperature for the fixation of special paper such as thick paper, the control means 17 drives the motor 14 for the constant time from the switching to drive the pressure roller 12 by the heat roller 11. This constitution allows the fixation temperature to set speedily even in a low room temperature state and prevents a defect in fixation from occurring.

Title: Multiple-ray type face sensor switch
Inventor: NAKAJIMA MIKIO
IPC: H01H35/18
Filed: 1987-11-18
Abstract: PURPOSE:To detect an insensitive area between a projector and a receptor by a method wherein a plural number of projectors and receptors are placed on both sides of a sensor area and while a projector is operating, a receptor is periodically changed over. CONSTITUTION:Projectors P1-P4 and corresponding receptors R1-R4 are placed at specific intervals on both sides of a sensor area 10. Projectors P1-P4 project rays, which are pulse-modulated by a pulse signal supplied from a projection oscillation frequency circuit 12 via a projector changeover switch 14, to the sensor area 10 via a lens 16. The projected rays are received by receptors R1-R4 via a lens 18. When the projector changeover switch 14 is switched and one projector is operating, receptors are periodically switched by a receptor changeover switch 20. This allows not all receptors to receive a ray at the same time but allows receptors to sequentially receive it one by one. Therefore a ray from one projector can be projected to not only a facing receptor but also other receptors.

Title: Data recorder
Inventor: HAGIWARA MOTOHARU
IPC: G11B15/467
Filed: 1990-10-29
Abstract: PURPOSE:To improve effective utilization rate of a tape with a reduction in a margin area part by a method wherein automatic track following servo is turned OFF after the detection of a postamble by a postamble detection means and turned ON after a specified time elapses to read data. CONSTITUTION:Data are recorded on a tape intermittently through a preamble area 14 and a postamble area 17 and in reproduction, a signal of the postamble area is detected by a postamble detection means 19 to shift an automatic track following servo (ATF) detection means from ON to OFF state. During the period, the ATF servo fails. The ATF servo is turned ON with a reproduction head contacting the preamble area 14 to be stabilized and in the reproduction, data are read out with the ATF applied sufficiently. Thus, an amount of data to be recorded on the tape increases with a decrease in margin area to be recorded on the tape thereby improving effective utilization rate of the tape.

Title: Method for removing silicon content in hydrochloric acid-pickled waste liquid
Inventor: KONDO HIDENOBU
IPC: C01G49/10
Filed: 1986-12-08
Abstract: PURPOSE:To relatively readily remove SiO2 in a hydrochloric acid pickled waste liquid of steel stock and effectively perform production of high purity iron oxide, by stirring the hydrochloride-pickled waste liquid of steel stock and then filtering the separated solid content using a filter having a specific pore size. CONSTITUTION:A hydrochloric acid-pickled waste liquid of steel stock is stirred and a solid content in the above-mentioned waste liquid is filtered using a filter having average pore size of >=0.1 to remove silicon content. When the above-mentioned stirring is too strong, aggregating SiO2 is often broken. Therefore, for example when an impeller is used, stirring rate of <=about 200rpm is preferable and when gas bubbling is carried out, gas flow rate of about 0.1-1Nm<3>/min based on the pickled waste liquid of 1m<3> is preferable. When the stirring temperature of the pickled waste liquid is too high, aggregation of SiO2 is promoted, but solubility of SiO2 is remarkably increased. When the stirring temperature of the pickled waste is too low, much time is required for aggregation. Therefore the stirring temperature is preferably about 40-60 deg.C.

Abstract: PURPOSE:To enable foreign matter to be caught with no wire net mounted by forming a clearance, having a space smaller than a grain size of the foreign matter, in a hydraulic equipment in its oil path. CONSTITUTION:A slit groove 12, having a width H1 a little smaller than the grain size of foreign matter to be caught, is formed in a poppet 3 in the peripheral direction of its small contour intermediate part 8. In this way, because the foreign matter in oil circulated in an oil path can be caught by the slit groove 12, the foreign matter can be caught without mounting a wire net.

IPC: G11B5/82
Filed: 1986-12-10
Abstract: PURPOSE:To obtain a magnetic disk having less injuries to be caused by collision of a magnetic head and a magnetic disk, by using glass to a foundation layer. CONSTITUTION:For instance, a glass thin plate of 0.1mm is adhered onto an aluminum disk having thickness of about 2mm. This glass foundation 2 has higher hardness than a conventional foundation made of NiP, etc. Thus, the deformation of a magnetic disk to be caused when a magnetic head collides against the disk in concentrating to a minute point of the disk. Then the injuries of the disk can be prevented. At the same time, the heat expansion coefficient of a metallic base is increased compared with the glass 2 together with a temperature set at a level higher than the maximum working temperature for adhesion. Thus the compression stress can be applied to the glass 2, therefore if a minute crack is produced on the glass layer 2, its growth can be prevented.

IPC: H01Q19/10
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To improve short-distance radiation characteristics while maintaining long-distance radiation characteristics by providing a reflection member nearby an antenna opening. SOLUTION: The radius of a range 105 wherein transmission to and reception from one base station 104 are possible is several km. In the semimillimeter wave or millimeter wave band, the linearlity of a signal is strong and visibility needs to be secured between the antenna of the base station 104 and the antennas of subscriber stations 101 to 103; when a communication is made in a vertically looking-down state, a vertically upper subordiante lobe 4a of a horn antenna does not contribute to the communication. A conductive reflective member 3 above the antenna opening 2a makes adjustment so that the vertically upper subordinate lobe 4a which does not contribute to the communication is radiated vertically downward. Thus, while the characteristics of the main lobe 5 are maintained, communication environment in a relatively-short-distance and small-gain service area can be improved and the antenna electric power is effectively utilized by using the subordinate lobe 4a which does not contribute to the communication.
