Title: Paper feeder for electronic copying machine
Inventor: KASHIWAKURA YUJI
IPC: B65H5/36
Filed: 1985-09-30
Abstract: PURPOSE:To make a skew of copying paper in size below a distance between a manual paper feeding pickup roller and a feed roller pair preventable, by extending the widthwise adjustable manual paper feeding guide installed in a manual paper feeding part as far as the vicinity of the feed roller pair. CONSTITUTION:When copying paper is inserted into a manual paper feeding part 4, a manual feed switch 17 turns on, a solenoid 18 draws a link 19, a manual feed pickup roller 8 goes down with its own weight, and a feed roller pair 5 and the roller 8 both rotate, conveying the copying paper to a sensitizer drum piece by piece. Here, since the side of the feed roller pair 5 of a manual paper feeding guide 30 is extended as far as the vicinity of the roller pair 5, even in case length of the copying paper is almost equal to a distance between the roller 8 and the roller pair 5 or shorter, in the paper feeding process, the copying paper is surely preventable from being skewed and, what is more, the paper is conveyable to the sensitizer drum in a normal state all the time, thus a good copy is securable.

Title: Double cloth for papermaking
Inventor: TATE TAKUO
IPC: D21F1/10
Filed: 1989-08-25
Abstract: PURPOSE:To prevent upper-layer weft yarns from their being depressed on a papermaking surface and obtain the subject cloth forming a smooth papermaking surface without any recessed parts by forming long crimps in the upper-layer weft yarns and forming crimps having a length of 3 or more warp yarns by a specific method. CONSTITUTION:Each warp yarn is arranged so that the adjacent 2 upper-layer weft yarns may be woven by one warp yarn and the next adjacent 2 weft yarns at an interval of 3 weft yarns from the upper-layer weft yarn woven with the initial warp yarn may be woven with the adjacent next warp yarn. Thereby, long crimps and short crimps are alternately arranged in the respective upper-layer weft yarns. The long crimps and short crimps are adjacent among the adjacent upper-layer weft yarns. Since the mutual long crimps and short crimps are prevented from adjoining, regular arrangement of crimps in the oblique direction of the warp yarns formed on the upper-layer weft yarns on the papermaking surface is divided into sections by the long crimps of the upper-layer weft yarns to prevent marks in the oblique direction from occurring in paper.

Title: Metal evaporation method
Inventor: MUKODA HIDETOSHI
IPC: B01D59/34
Filed: 1989-08-25
Abstract: PURPOSE:To lower heat loss and heighten evaporation efficiency by irradiating a porous tungsten with an electron beam which contains bubbles and in which a metal for evaporation is impregnated. CONSTITUTION:For example, porous tungsten mixture 2 which contains bubbles and in which a metal such as uranium is impregnated is put in a crucible 3 and the surface of the mixture is irradiated with an electron beam 4. Temperature of the electron beam irradiated spot increases and thereby uranium impregnated in the mixture 2 is evaporated. As a result, equivalent thermal transmittance is lowered owing to the bubble and heat loss to the crucible cooled by water is lowered and thus evaporation efficiency is improved.

Title: Facsimile equipment
Inventor: EDAMURA TOSHIAKI
IPC: H04N1/21
Filed: 1992-07-24
Abstract: PURPOSE:To extend the service life of a disk device by utilizing the disk device for the storage of picture information while the power is applied to the disk device when an idle capacity of a picture memory is decreased. CONSTITUTION:Power of a disk device 9 is interrupted usually. When information comes to the facsimile equipment, the facsimile equipment receives sequentially the sent picture information and stores the information to a picture memory 4 in each prescribed unit information. Then the idle capacity of the picture memory 4 is checked. When the idle capacity of the picture memory 4 is less than a preset allowable capacity, the state of the power supply of the disk device 9 is checked and the power is applied. When power is applied to the disk device 9, accessing such as storage of picture information is attained after lapse of a prescribed time of 10sec or the like, the picture information stored in the picture memory 4 is transferred to the disk device 9 to make the picture memory 4 idle. Thus, the received picture information is tentatively stored at first in the picture memory 4 and then transferred to the disk device 9.

Title: Photomagnetic recording medium
Inventor: SHIMODA TATSUYA
IPC: H01F10/12
Filed: 1984-10-17
Abstract: PURPOSE:To form a mass-producible photomagnetic recording medium having excellent weatherability and temperature characteristics at a low cost by a method wherein an amorphous ferromagnetic thin film, having the specific composition and the axis of easy magnetization in the direction vertical to the film surface, is used. CONSTITUTION:An Nd-Fe-Ni-B thin film is formed on a substrate, and a mag netic thin film is formed in amorphous structure using a specific composition, thereby enabling to form the axis of easy magnetization in the direction vertical to the film surface. When the magnetic thin film is formed in Nd100-xFex, this alloy can be made amorphous in the approximate range of 60<x<95. Beside, when B is added to said Nd-Fe 2 element, the ferromagnetic property is stabi lized, and the Curie point and the saturated magnetization of the alloy can be improved. The addition of B is effective even when its quantity is small. As the ferromagnetic property becomes unstable when the addition of B is 20atm% or above, the addition of B is to be between 0.01 and 20atm%. The magnetic property is deteriorated when Fe is replaced with Ni in order to improve weatherability, but the deterioration of the magnetic property can be compensated by B.

A discriminating means 6 discriminates the amplitude level of the waveform of the tracking error signal passed through the low-pass filter changed over by the changeover means 4. A pulse generating means 7 generates track counting pulses based on the discriminated result of the discriminating means 6.

Title: Agc amplifier
Inventor: KONDOU KUNIO
IPC: H03G3/02
Filed: 1983-11-19
Abstract: PURPOSE:To set a desired AGC characteristic easily by applying A/D conversion to an input average value and using a digitized data so as to adjust the gain or the titled amplifier. CONSTITUTION:An average value detecting circuit 3 detects an absolute value or a half wave rectified value of an input signal Vi, averages it and an A/D converter 4 converts an output Vf of the circuit 3 into a digital signal Di. The gain of a variable gain amplifier 6 is controlled by a digital signal D0 from an ROM5 outputting digital signal taking the signal Di as an address. Thus, the desired AGC characteristic is realized by taking the content of the ROM5 as a value corresponding to its characteristic and the AGC characteristic is changed by having only to change the content of the ROM5 without changing the circuitry.

Title: Video disk player
Inventor: YAMASHITA NORIYUKI
IPC: G11B19/247
Filed: 1992-07-24
Abstract: PURPOSE:To lock in phase a video signal to be reproduced on a frame signal having a reference phase in a video disk player. CONSTITUTION:A pilot signal SP reproduced from a video disk VD or an alternating signal S44 synchronized with this pilot signal SP is frequency divided. The rotation of the video disk VD is servo controlled so that this frequency divided signal S63 is locked in phase on a reference signal REFH2M. When the servo control is started, a frequency dividing ratio N is altered from the reference value N to (N+DELTAN) with a fixed period by every fixed interval. At every time when the phase relation between the frame signal PBFM of the video signal SMS reproduced from the video disk VD and the reference frame signal REFFM is inverted, the sign of the value DELTAN is inverted between positive and negative, the absolute value ¦DELTAN¦ of the value DELTAN is made successively small. Consequently, the frame signal PBFM of the video signal SMS reproduced from the video disk VD is locked in phase on the reference frame signal REFH2M.
