Title: Production of magnetic powder
Inventor: MINOURA YASUYUKI
IPC: H01F1/11
Filed: 1985-09-27
Abstract: PURPOSE:To produce the titled magnetic powder having uniform crystal grain diameter, a stabilized magnetic characteristic and excellent dispersibility by adding a specified metal to an amorphous material obtained from the building component of hexagonal ferrite and a vitrifying component and then heat- treating the mixture. CONSTITUTION:A mixture of the building component of hexagonal ferrite consisting of 30-40mol% BaO, 25-40mol% B2O3 and 15-35mol% Fe2O3 and a vitrifying component is heated, melted and then quenched to obtain the amorphous material. Then 10-3,000ppm of at least one kind of metal selected from Ni, Cr and Mn is added to the amorphous material. The mixture is packed in a heat-resistant vessel and heat-treated to deposit the sintered body of a hexagonal ferrite crystal. Then the sintered body is pulverized, washed with a dilute acid at >=80 deg.C to dissolve and remove the vitreous substance, and then washed with water until the pH is controlled to >=6. Consequently, magnetic powder having 0.01-0.3mum particle diameter and appropriate for high-density magnetic recording is obtained.

Title: Press roller
Inventor: KANAI TERUO
IPC: B32B5/18
Filed: 1992-07-20
Abstract: PURPOSE:To provide the roller which satisfies the adequate conditions necessary as the press roller, such as paper wrinkling, envelope wrinkling, flexibility and toner peelability, by forming a silicone sponge layer of an open cellular sponge.

Patent JP-S6471201-A (JP)
Title: Static magnetic wave resonator
Inventor: JIYUZETSUPE MITSUKOORI
IPC: H03H2/00
Filed: 1988-08-29
Abstract: PURPOSE:To suppress an undesired mode by providing an input converter gener ating a traveling wave in a direction of a front number of a traveling wave component of the required resonance fundamental mode and an output converter responding optimizingly to one of traveling wave components of the required resonance fundamental mode. CONSTITUTION:An input microstrip conductor 42 is arranged on one diagonal line of a yttrium iron garnet (YIG) film 41 on a base 40 and an output microstrip conductor 43 is arranged on the other diagonal line respectively in the resonator. The length of the overlapped part between the conductors 42 and 43 is expressed as (L +L)<1/2>. Since the overlapped length is increased more than that of a conventional resonator, the coupling intensity of an electric signal in the microstrip with the static magnetic resonance by the YIG film 41 is increased. Since the coupling in the required resonance mode is maximized, not only the resonance response in the mode is increased, but also the residual energy quantity to be coupled in the other resonance mode is decreased. Thus, the energy in the undesired mode is decreased.

Title: Picture display device
Inventor: SAKAMI YUUJI
IPC: H04N1/387
Filed: 1982-12-08
Abstract: PURPOSE:To extract and edit an optional picture with a system where a displayed picture is displayed as a toner image, by designating the position with a light spot given from the back of an image carrier. CONSTITUTION:The rear side of a belt 4 is irradiated by a spot light source 14 for designation of position, and a focal point is formed on the belt 4. When only the information enclosed by spots 24-27 is extracted, the light source 14 is shifted to a position 24 or 26. This shift is carried out by motors 18 and 23 and wires 15, 20a and 20b. When the light source 14 is positioned at a desired place, a signal is transmitted by an appropriate switch. Thus the coordinates of the place are read in the form of electric signals from revolving angles of motors 18 and 23. If the source 14 is first shifted to the position 24 (26), the source is shifted to the position 26(24) in the same way. Then the coordinates of the position are read in the same way. The coordinate information on the two spots is fed to an electronic computer or a picture reader. Thus it is possible to extract only the range of desired information which is enclosed with 4 spots.

Title: Time base correcting device
Inventor: OHASHI KAZUHITO
IPC: H04N9/89
Filed: 1987-08-31
Abstract: PURPOSE:To effectively correct a time base with a simple constitution, by inverting either one phase of a color burst signal or a storage timing signal at every prescribed period synchronously with a synchronizing signal included in a picture signal. CONSTITUTION:At the time of storing the picture signal in a storing means 20 synchronously with the phase of the color burst signal by a phase control means 109, either one signal of the color burst signal or the storage timing signal is inverted at every prescribed period by inverting means 106, 107, 108, S2. Therefore, since the dislocation of the phase of the color burst signal in the picture signal can be compensated, the time base can be properly corrected with the simple constitution without a complicate constitution.

Title: Thermo-sensing recorder
Inventor: KATO SADAMIKI
IPC: B41J2/32
Filed: 1988-08-30
Abstract: PURPOSE:To decrease number of control circuits by providing a readout control circuit outputting a latch signal for each output of transfer clocks of a number being the division of one scanning line picture element number by number of times of readout, a shift register having number of stages being one over the number of times of readout of the number of picture elements of one scanning line and data latches of the same number as the shift register stage number. CONSTITUTION:Even number picture information sets p2, p4 in one scanning line transferred to shift registers S1, S2 are latched in data latches L1, L2 by using a data latch signal (c). The picture signal input by the succeeding one scanning line is attained to the shift registers S1, S2. When a print instruction signal (e) is supplied from a readout control circuit 1, data outputs d1, d2 of the data latches L1, L2 are ANDed with the print instruction signal (e) by AND circuits A1, A2. Only when the print instruction signal (e) is true and the data outputs d1, d2 are black level information, driver circuits D1, D2 drive heat resistors R2, R4 energized from a power supply f2. Thus, number of control circuit groups is halved than those of a convention recorder.

Title: Display valve of overcurrent passage display device
Inventor: ISHIGURE MASAO
IPC: G01R31/02
Filed: 1981-12-29
Abstract: PURPOSE:To obtain the display valve of the overcurrent passage display part which can sink under its own weight through a colored fluid under a stable state, by making the specific gravity of fan shaped valve pieces constituting the display valves larger than the colored fluid, making the specific gravity of a coupling member smaller than the colored fluid, thereby making the lower part of the display valve heavy. CONSTITUTION:In the valve body 31, the coupling member 34 is smaller than the fan shaped valve pieces 33. Therefore intervals Q formed between the fan shaped valve pieces 33 are exposed. Said parts constitute a plurality of cut in parts 45 formed at the outer surface of the valve body 21. The cut in parts 45 serve the role of flow paths for the colored fluid 29 located at the lower surface of the valve body 31, when it sinks by its own weight. The valve body 31 is guided by the colored fluid 29 flowing upward through the flow path, and the valve body 31 can sink under the stable state. The specific gravity of the fan shaped valve piece 33 is made larger than that of the coupling member 34. Therefore, the fan shaped valve piece 33 never moves upward with its central part as a center when the valve body 31 is lifted or lowered. Since the center of gravity is positioned at the lower part of the valve body 31, the up and down movement of the valve body is made very stable.
