Title: Image processor
Inventor: HORI MOTOFUMI
IPC: G06F3/12
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To reduce data quantity to be transferred to a printer on a network only by performing relatively simple configuration change. SOLUTION: When the PDL command generating device 31 of this image processor receives a plotting instruction (object unit) from a plotting library, it interprets the contents of the object, generates a PDL command proper to each printer and also inquires of a command extracting device 32 whether or not the generated command should be transmitted to the printer. A command comparing/storing device 33 stores prescribed commands transmitted to printers in the past. The device 32 notifies of 'invalidity' when the generated command is an already issued command and notifies of 'validity' when it is an unissued command. When the device 31 obtains notification that it is 'invalid', it does not transmit the command.

Title: Magnetic fluid magnetic sensor
Inventor: OTA KAZUHIDE
IPC: G02F1/09
Filed: 1990-03-05
Abstract: PURPOSE:To detect a very weak magnetic field with good accuracy by forming a side wall of a cell narrow in width where a magnetic fluid is sealed by each end of a pair of magnetic lenses where the magnetism is concentrated. CONSTITUTION:Magnetic lenses 18, 20 form narrow ends 18a, 20a where the magnetism is concentrated, and wide ends 18b, 20b at the other sides from which the magnetism is taken. The ends 18a, 20a are arranged adjacent and confronting to each other between glass plates 12 and 14. In this case, the magnetic flux taken from one magnetic lens passes effectively to the other magnetic lens without leaking. Besides, since the width L1 at the ends 18a, 20a is formed considerably smaller than the width L2 of the other ends 18b, 20b, the magnetic flux can be concentrated sufficiently from the take-in ends to the concentrating ends. Therefore, the magnetic field, particularly, the very weak magnetic field can be detected with good accuracy with use of double refraction.

IPC: H01Q21/20
Filed: 1988-03-07
Abstract: PURPOSE:To prevent the communications of all subscribers to exist in the range of 90 deg. from being troubled even when a trouble is generated to one antenna by fitting the antennas to the tips of respective waveguides divided into plural stages, respectively. CONSTITUTION:A waveguide 14 connected to a transmitter-receiver 10 installed in a radio station is divided into plural stages by plural distributors 12, antennas 16 are fitted to the tips of respective waveguides, respectively, the waveguide path lengths of the waveguides 14 between the transmitter-receiver 10 and respective antennas 16 are composed to be equal in order to prevent a phase shift, and simultaneously, plural columns 18 to install the antennas 16 are ar ranged in an approximately circular shape. Thus, since each antenna is directed to one subscriber, even when the trouble is generated to one antenna, all subscribers to exist in the range of 90 deg. can be prevented from being troubled as in the case of a system to adopt a fan beam antenna, a propagation length difference in microwaves radiated from the adjoining antennas can be canceled, and a wave interference can be prevented.
