Title: Ink jet recording device and discharge recovery device for same device
Inventor: IWATA KAZUYA
IPC: B41J2/175
Filed: 1990-02-13
Abstract: PURPOSE:To make it possible to send out almost all ink to a waste ink storage member from the inside of a pump by a method wherein by initial several drivings of a plurality of drivings of a piston, ink is taken into a pump sufficiently from an acceptance member with less back flows, and during a final designated drivings, the piston is driven at a full stroke. CONSTITUTION:When a piston 525 runs over a valve port 531 and further advances to the right, since the piston 525 is pressed by and joined to a shaft flange part of the piston 527a fromt be left side, generated negative pressure is transmitted to a carriage side 51 without leaking to others. Also, ink which has stayed on the right side of the piston 525 is pushed out to a waste ink tank. In this case, a pump 53 does not have a member which is equivalent to a valve for a normal pump, and there are occasions in which back flow generates to a cap 51 side when positive pressure generates in the pump. Therefore, by keeping the valve mouth 531 closed with the piston 525 unless it is required to be opened, back flows can be reduced.

Title: Voice recognizing method
Inventor: KOGA SHINJI
IPC: G10L15/06
Filed: 1988-02-09
Abstract: PURPOSE:To eliminate the need of a huge calculation and to decrease a drop of a recognition rate by comparing and collating a feature vector time series which has been obtained by applying a feature analyzing process and the second standard pattern with respect to an unknown sound signal. CONSTITUTION:An unknown sound signal S is converted to a feature vector time series V by a feature analyzing part 1, and this feature vector time series V and a standard pattern P in the second standard pattern generating part 6 are read in a comparing and collating part 7. The probability for outputting the feature vector time series V from these parameters is derived by the number of standard patterns by a forward/backward algorithm. Subsequently, a category O of the standard pattern in which said probability is maximum is derived, and outputted as a result of recognition. In such a way, a huge calculation at the time of generating the standard pattern becomes unnecessary, and also, by a quantizing error which follows up a vector quantization, a drop of a recognition can be suppressed.

Title: Wide area scanning image pickup device
Inventor: HAMADA KATSUHIKO
IPC: H04N5/372
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a miniaturized device with a little components for a driving mechanism while keeping a wide and uniform view by installing an optical system for correction with which only the arranging direction of elements can be corrected through the mechanical scan of one axis only by omitting the mechanical scan by replacing the scan of one axis of required image angle with a wide angle optical system. SOLUTION: A light beam 1 radiated from a target gets a turn axis upset area secured by a turn axis scanning mirror 9 rotated by a turn axis driving system 3 and an elevation axis upset area secured by a wide angle optical system 11. In this case, a derotation optical system 10 is provided just after the turn axis scanning mirror 9 and rotated oppositely at the same rotating speed as the turn axis scanning mirror 9, and the rotation of image is relatively canceled. Besides, since lightness at the peripheral part of a picture is lowered by distortion aberration concerning the wide angle optical system 11, a correction optical system 12 composed of a cylindrical lens having a curvature change only in the direction of elevation axis is installed for this correction. Thus, one scanning mechanism can be omitted.

Title: Rotary drum for magnetic head of magnetic recording and reproducing device
Inventor: OGURA MITSURU
IPC: G11B15/61
Filed: 1983-02-24
Abstract: PURPOSE:To eliminate unuiformity of recording and reproducing characteristic by constituting a groove engraved just above a magnetic head wider and also deeper than other grooves to uniform the thickness of air layer formed between a rotary drum and a video tape. CONSTITUTION:The groove 2a just above the magnetic head 4 among three grooves on the surface of the cylinder of the rotary drum is engraved wider and deeper by two times than the other two grooves. The ununiformity of the thickness of air layer is improved remarkably in comparison with a conventional rotary drum by constituting the groove only just above the magnetic head larger than the other grooves, and this tendency is made eminent further by connecting holes for adjusting magnetic head fitting position in the rotary drum. Thus, the uniformity of the clearance between the magnetic tape and the magnetic head rotary drum is improved and the magnetic head rotary drum of the magnetic recording and reproducing device having excellent signal recording and reproducing characteristic is obtained.

Title: Printing method using line thermal head
Inventor: SOGABE MASUO
IPC: B41J2/325
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To form a clear print even under a state where a print object sheet is stationary by moving a thermal transfer ribbon tape at a lower speed than the print object sheet in a region where the relative speed between the print object sheet and a head is low and increasing the passing speed of head contact part at the time of printing. SOLUTION: Printing is performed while increasing the passing speed of head contact part by moving a thermal transfer ribbon tape 2 at a higher speed than a print object sheet 1 in a region where the relative speed between the print object sheet 1 and a head 3 is low. Since the thermal transfer ribbon tape 2 is moved at a higher speed than the print object sheet 1 and the passing speed of a head contact part is increased, a clear image can be obtained even in a low speed region. Moving speed of the thermal transfer ribbon tape 2 is set at about 0.5-1 cm/sec when the moving speed of the print object sheet 1 is 10 cm/sec.

Title: Optical switch
Inventor: MIKAMI OSAMU
IPC: G02F1/03
Filed: 1978-03-17
Abstract: PURPOSE:To reduce the total length and the loss in optical transmission by making integral two 3 dB couplers and an optical modulator in one optical waveguide composed of a linear portion. CONSTITUTION:If a voltage is impressed upon electrodes 7 and 8, the depthwise electric field is established in a concentrated manner below the electrodes. Since waveguides 2 and 3 are preset in the region having the electric field concentrated, there is established a phase difference DELTAbetaE between the waveguides. At an optical modulator 6, on the other hand, a thin film 14 for phase misalignment is mounted only on one waveguide 3. As a result, the coefficient of transmission of the waveguide 3 has been varied more than that of the waveguide 2 to that the phase difference DELTAbetaL inbetween can be made sufficiently larger than the coupling coefficient K of the intrinsic type between the two waveguides. As a result, no shift of optical waves takes place upon the phase misalignment. As a result, after the DELTAbetaL takes a preset value by the charge of the thin film 14, the intensity of the waveguides 2 and 3 at their emanating ends can be varied from 0 to 1 by varying the value DELTAbetaE within a range of ¦DELTAbetaE¦<pi.

Abstract: PURPOSE:To improve the resolution of the solid-state image pickup device by tilting a plane formed by the solid-state image pickup elements by a prescribed angle with respect to a plane orthogonal to an optical axis of an optical lens and arranging plural photodetectors in an arc form. CONSTITUTION:Linear solid-state image pickup elements 70 are tilted by an angle theta with respect to a plane perpendicular to an optical axis of an optical lens 8 to form an optical system. Since a cross line between the plane of the one-dimensional solid-state image pickup elements 70 tilted by an angle theta and a focal plane of the optical lens 8 is a curve being a circular-arc, photodetectors 20 are arranged on the curve formed on the plane of the one-dimensional solid- state image pickup elements 70 to curve an arrangement curve 20' of the photodetectors 20 on the linear solid-state image pickup elements 70 in an arc curve to locate each of the photodetectors 20 on a focal plane of the optical lens 8 simultaneously. Thus, a deviation in the resolution around a central point (point A) and around ends (point B)is not caused different from that having been observed in a conventional one-dimensional solid-state image pickup device.
