Title: Waffle iron type filter
Inventor: ISODA YOUJI
IPC: H01P1/211
Filed: 1983-04-05
Abstract: PURPOSE:To put resonance due to a wave in high-order mode out of an in-use band almost without exerting influence upon the passing characteristics of a basic mode wave by making bosses uneven in height. CONSTITUTION:Bosses 3 which are high enough for necessary filter characteristics are provided near the center of a rectangular waveguide 1 and bosses 4 which differ in height from the bosses 3 are provided near narrow-width surfaces of the rectangular wave-guide 1. The electric field of the basic mode wave is small at the bosses 4, which, therefore, exert almost no influence upon the passing characteristics of the filter. The electric field of the high-order mode wave, however, is larger at the bosses 4 than the electric field of the basis mode wave, so the rate of wavelength shortening increases and the resonance frequency of the high-order mode wave varies greatly. Therefore, unnecessary resonance by the high-order mode wave is put out of the in-use resonance.

Title: Recording method

IPC: B41J2/165
Filed: 1979-05-16
Abstract: PURPOSE:To accomplish simple recording without causing nozzle clogging dispensing with ink deflection means by projecting above the ink liquid level the top of the piezoelectric element stretched by the application of voltage to contact ink with the recording material. CONSTITUTION:The image signal generator 6 selectively provides the signal current to the plate 4 corresponding to the image to be recorded so that the potential of the plate 4b is maintained at a given level only for a fixed time and a given voltage is applied between the electrode 4b and the plate 4a facing it to stretch the piezoelectric element 3. When the signal current is given for example, to the first and third plates 4b viewed from the left of the drawing, the piezoelectric element is stretched only for a fixed time projecting the top thereof above the liquid level of the insulating ink so that the insulating ink 2a on the top thereof is put on the recording material in contact therewith. As the voltage applied on the piezoelectric element 3 becomes less after a fixed time elapses, the piezoelectric element 3 reduces allowing the top thereof to enter the insulated ink 2.

Abstract: PURPOSE:To retrieve a large quantity of data at a high speed to plural retrieving inputs by allocating the record corresponding to a key word to a retrieving file and taking the register information common to the retrieving inputs out of the record corresponding to a key word having the lowest register frequency. CONSTITUTION:A CPU 1 is provided to perform various types of arithmetic processing or decision processing together with a memory 2, a keyboard 4, a display 5, an input/output part 3, an external storage control part 6, and a common bus 8. The register frequency of a key word to be registered is counted for production of a register frequency-key word table. Furthermore a retrieving file is produced to store the registered key words having the register frequencies higher than that of the preceding key word and the register information in pairs. Then the key word having the lowest register frequency is taken out of the key word table, and the register information common to plural inputted retrieving key words is taken out. Thus a large quantity of information can be retrieved at a high speed with use of plural retrieving inputs.

Filed: 1980-05-06
Abstract: PURPOSE:To divide a voltage with a high precision, by dividing the differential voltage between the upper limit voltage and the lower limit voltage by the change of the feedback resistance of an operational amplifier independent of the current change. CONSTITUTION:The upper limit voltage V1 and the lower limit voltage V2 are input to a differential amplifying circuit 1 to output the differential voltage -(V1- V2).

Title: Developing device
Inventor: HOSOI ATSUSHI
IPC: G03G15/09
Filed: 1987-03-16
Abstract: PURPOSE:To prevent loss of carrier particles and to permit formation of a good-quality image with high development efficiency by disposing a developing magnetic pole to face a latent image carrier and slowing down the dropping way of the magnetic flux density on the down stream side in the rotating direction of a developing sleeve. CONSTITUTION:The developing magnetic pole 3c is so set as to have the max. magnetic flux density in the part opposite to a photosensitive body, to weaken the magnetic force thereof sharply toward the upper stream side in the rotating direction of the developing sleeve 2 and to drop the magnetic force gently toward the down stream side. A developer layer, therefore, rises sharply just before the development region and is directly rubbed onto the surface of the photosensitive body 1, by which the toner detached from the carrier particles 7 generated by the movement arising from the napping of the develop layer is easily transferred to the photosensitive body 1. The detached toner is thereby prevented from splashing. The developer layer is napped and the developing sleeve surface is opened in the development region. Flying of the toner from the developing sleeve surface and the carrier particles is actively executed by alternating electric fields. Most of the toner existing in the development region are thereby subjected to the development and, therefore, the good-quality image having the extremely high development efficiency is obtd.
