Title: Radio repeater for mobile body
Inventor: AOZUKA TORAO
IPC: H04B7/15
Filed: 1992-08-26
Abstract: PURPOSE:To provide a radio repeater relaying a broadcast wave received by a train. CONSTITUTION:A broadcast wave reception antenna system 1 in which a bar antenna 19 is arranged in parallel with a contact wire is fitted to a roof of a vehicle. A received AM wave is amplified by RF amplifiers 2, 3 and inputted to a buffer 4 being a switching means. When a train is running through a location whose electric field intensity is not in excess of a prescribed level, AGC circuits 9-13 are operated and a radio wave whose intensity is constant radiates into the cabin through a distributer 18. On the other hand, when the train is running at a location whose electric field intensity exceeds a prescribed level (90dB/m), an output of the RF amplifier 3 is extracted by a diode 6 to avoid interference between a relay wave and a direct wave and when its output level exceeds a prescribed level, the buffer 4 is inactivated based on an output of a buffer on/off control circuit 8. As a result, the radio wave is not relayed and the direct wave is received. In order to prevent chattering, the restoration to the buffer ON state is delayed through the provision of a capacitor 7.

Title: Electrostatic charge image developing toner
Inventor: AKASHI YASUHISA
IPC: G03G9/087
Filed: 1989-09-28
Abstract: PURPOSE:To enhance offset resistance, blocking resistance, and development characteristics, and to enlarge fixing temperature range by copolymerizing a binder resin obtained by copolymerizing a monomer having a carboxylic group with a copolymerizable monomer, then treating it with alkali, and reacting it with a metallic compound. CONSTITUTION:The binder resin is prepared by copolymerizing a monomer having a carboxylic group with a copolymerizable monomer, then treating it with alkali, and reacting it with a metallic compound. The resin itself can be elevated in polarity by introducing acid groups, the carboxylic groups are used for cross-linking of the metal compound by alkali treating the carboxylic groups, and the rest of the carboxylic groups are converted into their anhydrides. Most of these carboxylic groups in the binder resin participate in these reactions. The binder itself can be given sufficient negative chargeability when the carboxylic groups are made anhydrous, thus permitting offset resistance, blocking resistance, and development characteristics to be enhanced and the fixing temperature range to be enlarged.

Title: Liquid crystal display device
Inventor: KOMA TOKUO
IPC: G02F1/1343
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To allow a reflection type liquid crystal display device to reduce visual angle dependency maintaining a high numerical aperture and increase in an angle of visibility. SOLUTION: An orientation control electrode 13 is distributed between every two columns of display electrodes, and also an orientation control window 22 is distributed between every two columns and every line. In a side which the orientation control electrode 13 and an orientation control window 22 are lining, a diagonal electric field is formed inclining in the same direction of the opposing side, and an orientation of a liquid crystal is controlled with respect to its picture elements in a same direction. Since each picture element is different in preferred visual angle direction, macroscopic visual recognition of them averages luminous intensities and contrast ratios, reducing a visual angle dependency, and increasing an angle of visibility.

Title: Document preparing device
Inventor: HORIKOSHI KOJI
IPC: G06F17/21
Filed: 1991-09-30
Abstract: PURPOSE:To realize an optimum processing for an input character string where the period of an abbreviated word exists by executing a spelling check processing based on an English word dictionary including the period in a docu ment generation deice having an English spelling check function. CONSTITUTION:When the period is not detected from the input character string, CPU 1 executes the English spelling check processing of the input character string based on the regular English word dictionary 8a of ROM 8. When the period is detected from the input character string, CPU 1 executes the English spelling check processing for the input character string based on an English word directionary 8b including a period in a ROM 8. In such a case, CPU 1 removes the period from the input character string when the English word coincident with the input character string cannot be detected in the English word directionary 8b. Then, spelling is checked based on the regular English word dictionary 8a. When it cannot be detected here, it becomes the error of the input character string.

Title: Magnetic disk device
Inventor: ABE YOJI
IPC: G11B25/04
Filed: 1986-10-24
Abstract: PURPOSE:To absorb vibration to be generated at the time of accelerating/ decelerating the speed of a voice coil motor by mounting and fixing a base on a chassis with a spring made of ultraelastic alloy in the same direction as the moving direction of the voice coil motor. CONSTITUTION:A magnetic disk device 3 is mounted freely with a roller 9 for the moving direction of the voice coil motor 7, and is fixed on the chassis 1 with the spring 2 made of the ultraelastic alloy. Since random access to a magnetic disk 4 on which data is written is performed in the magnetic disk device, a magnetic head 5 is mounted on the voice coil motor 7, and is driven linearly by the voice coil motor 7 and a magnetic circuit 6. By driving the voice coil motor 7 to the center side of the magnetic disk 4, the base 3 is moved in an opposite direction, and compresses an ultraelastic spring on the magnetic circuit 6 side, and expands a spring on the magnetic disk side. After completing the driving, since the spring 2 intends to restore to its original state, the magnetic disk goes to an initial state. In such a way, it is possible to absorb the vibration generated at time of accelerating/decelerating the speed of the voice coil motor.

Title: Snow-repellent cable
Inventor: SANAI MASAO
IPC: H02G7/16
Filed: 1987-10-06
Abstract: PURPOSE:To prevent an accident due to snow deposit beforehand by winding a spiral cable of low Curie material and another spiral cable of strong magnetism compactly about the external surface of a cable. CONSTITUTION:A flat armor rod 1 having a low Curie constant and another flat armor rod 2 having strong magnetism are wound compactly about the external surface of a cable 3, and the surface of the rods 1 and 2 is covered with a water-repellent material 4. According to the aforesaid construction, electric current flowing in a power cable is used, together with heat generated due to the eddy current of the strong magnetic substance and a hysteresis loss, to prevent the deposition of snow. Furthermore, the rod 1 becomes a magnetic substance only at a low temperature and generates heat due to the flow of electric current. This rod 1 turns to be non-magnetic at an ordinary temperature and does not generate heat. Consequently, overheat at the time of full current flowing in the summer season can be prevented. Also, the water-repellent material 4 repels a water drop and snow containing a large amount of moisture hardly deposits.
