Title: Driving method of magnetic bubble memory element
Inventor: OOHASHI MAKOTO
IPC: G11C19/08
Filed: 1982-02-22
Abstract: PURPOSE:To drive magnetic bubble memory elements without any loss of power consumption, by giving some difference between magnetic fields generated by two coils for producing a revolving magnetic field. CONSTITUTION:The two orthogonal coils for producing a revolving magnetic field 10 for driving magnetic bubbles are applied with 90 deg. out-of-phase alternating currents to generate magnetic fields Hx and Hy, and the magnetic field Hz operate to lead bubbles out of the cusp of a transfer line 8. Therefore, a minimum driving magnetic field is determined by the magnetic field Hx and the magnetic field Hy is made less than the magnetic field Hx to give some difference between the magnetic fields Hx and Hy. Consequently, the magnetic bubble memory elements are driven without any loss of power consumption.

IPC: G02B6/38
Filed: 1987-02-06
Abstract: PURPOSE:To prevent generation of various faults by interposing a metallic pipe between the connecting part side end of a nylon sheath and ceramic pipe. CONSTITUTION:A glass pipe 21 and the metallic pipe 23 are coated by the ceramic pipe 22. The metallic pipe 23 is a pipe made of stainless steel products and is formed to about 10mm length.

Title: Phase stabilizing method for cable
Inventor: HORI MASAHIKO
IPC: G01R31/02
Filed: 1979-03-06
Abstract: PURPOSE:To enable to monitor the electric length with accuracy at all times, even if the coaxial cable transmission signal source and the transmission signal detector are apart, by compensating the phase difference change between the phase detection signal and the reflection phase detection signal from the reflection section with the phase unit. CONSTITUTION:The signal fR from the reference signal source for phase detection enters the beginning end of the coaxial cable l with the directional coupler C1 and also enters the filter F1 at the end. The filter F1 passes the signal fs from the signal source transmitted on the cable l with the notch filter being the reflection section to fR and completely reflects the signal fR. Accordingly, the signal fR is reflected at the filter F1 and enters the detector DR from the directional coupler C2 coupled to the beginning end of the cable l through the coaxial cable l again. Since the signal fR reciprocates the cable l, the phase comparison between the signal fR and the detector DR enables the detection of phase difference with high accuracy.

Abstract: PURPOSE:To prevent the generation of a parasitic channel in an element isolation by etching the side surface of the groove of the element isolation region so as to region form an inclined plane with the tilt angle of 45 deg.-80 deg. to the surface of a substrate, burying an insulating film into the groove and flattening the groove. CONSTITUTION:A mask 22 is fomed onto the surface of the silicon substrate 21, and the groove 23, the tilt angle theta of the side surface thereof is 45 deg.-80 deg., is formed into the element isolation region through reaction ion etching. The ions of an impurity with a conduction type the same as the substrate are implanted by using the same mask 22. In this case, an ion implantation layer 24 is formed not only on a bottom surface but also on the side surface at the same time because the side surface of the groove 24 forms the inclined plane. An oxide film can be buried into the isolation region in a flat shape extending over the whole surface of the substrate through a process the same as a conventional method. As its embodiment, ions can be implanted simultaneously to the bottom surface and side surface of the isolation region by ion implantation at a time by sloping the side surface of the isolation region, and the generation of the parasitic channel can be prevented.

Title: Copying method from undulated original
Inventor: KOBAYASHI KAZUO

Filed: 1979-03-08
Abstract: PURPOSE:To enable copies to be readily obtained from undulated originals without soiling the original by letting the undulated original be pressure-contacted on the undulation detecting element provided with a pressure sensitive layer whose resistance value locally changes when pressed. CONSTITUTION:Toner 5 evenly deposits on the peripheral surface of developing roller 6 by a dector 7 and moves in the arrow B direction while the roller 6 revolves. In such a constitution, an undulated original 2 is pressure contacted to an undulation detecting element 3, by which the latent images consisting of low resistance portions and high resistance portions corresponding to the information of the undulated original 2 are formed on the undulation detecting element 3 and this turns out that the potentials on the surface of the copying paper 4 on the support layer 3c have the magnitudes corresponding to the information of the original 2. As a result of this, electrostatic latent images are formed on the copying paper 4 and these electrostatic latent images are made to sensible images by the toner 5 supplied by the developing roller 6. The copying paper 4 is subjected to fixing after this, so that it becomes a perfect copy.

Title: Optical flow estimating method and image compositing method
Inventor: CHIBA NAOKI
IPC: H04N1/387
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To ensure reliable optical flow even if there are not so many patterns in an image area by complementing optical flow in an area having low reliability which is calculated from two images with optical flow in ambient areas. SOLUTION: To estimate optical flow, after the optical flow is calculated in every patch based on two images, an area having low reliability is divided from an area having high reliability in accordance with the reliability of the optical flow. Next, optical flow in the area having low reliability is complemented by using optical flow in its ambient areas. The reliability γin this case is calculated by such a manner that its characteristic value is calculated from 2×2 coefficient matrices G of an expression I which has the square of vertical and horizontal differentiation of a certain image area ω and by an expression II from variable density residual E between a smaller characteristic value λmin and an area after following. Thus, it is possible to obtain a panoramic image without joints from plural images.

Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To suppress a noise due to latch miss by using a noise shaving technique by using the output point of the latch circuit of a D/A converting part for feedback as a signal fetching point from a feedback loop, and connecting it with an encoder. SOLUTION: A D/A converting part 14 for feedback is constituted of a latch circuit 141 with one sample time delay and a D/A converting circuit 142. A signal at the output side of the latch circuit 141 of the D/A converting circuit 14 for feedback is inputted to an encoder 15. The same data as data obtained by a conventional circuit are outputted after delayed only in one sample time, and S/N and precision is the same. Moreover, an adder 18 which adds an error E1 due to latch miss is provided between the D/A converting part 14 for feedback and a quantizer 13 so that noise shaving can be operated to the error E1 due to the latch miss. Thus, a latch miss noise in a signal band can be reduced by the suppression effect of a noise in a low frequency area due to the shaving by operating over-sampling.

Abstract: PURPOSE:To obtain a small-sized and light-weight common photosensitive unit based on a four-mirror system by controlling timing from the positional detection of a platen or an optical system to the start of a regist roller member in accordance with copying magnification. CONSTITUTION:Encoder pulses from a pulse generator in a body driving system are counted based on a reference signal obtained at an original platen 23 scanning home position detected by an HP sensor 46 and a working plate, and after a prescribed time, a regist roller clutch for starting a regist roller 37 and an eraser 28 are controlled so as to be turned on/off. Thus, registration for matching transfer paper 30 with the leading edge of an image and erasing of the leading and final ends of the image are controlled. Since the ON/OFF timing of the clutch and eraser is controlled in accordance with magnification based on a scanning home position detecting signal for the original platen 23, the registration or erasing can be prevented from being shifted even if the position of an image forming point on the photosensitive body 25 is changed at the variation of magnification.
