Title: Picture reader
Inventor: FUKUSHIMA SHIGENOBU
IPC: H04N1/00
Filed: 1990-03-12
Abstract: PURPOSE:To smoothly carry an original reverse by controlling the position of an original tray in the vertical direction so that the original carried reverse is not interfered with the original stacked in the original tray. CONSTITUTION:When an original read once by a read section is carried reverse toward an original tray 20 from a discharge tray 29, a lift-up plate 23 is pushed down and the original on the try 20 is saved downward. Then rollers 22, 25, 26 and a pickup roller 21 are reversed and the original is carried reverse toward the tray 20. Thus, the position of the tray 20 is controlled so that the original not carried and stacked on the tray 20 and the original carried reverse are not interfered with each other. Thus, the reverse carrying of the original is implemented smoothly.

Title: Adaptive control device
Inventor: FUJIWARA TOSHIKATSU
IPC: G05B13/00
Filed: 1984-03-30
Abstract: PURPOSE:To improve the control capacity for disturbance by correcting the parameter of a model by an adapting mechanism and feeding back it to a control system as a manipulated variable in an adaptive control device of the control system having a PI regulator. CONSTITUTION:When receiving a disturbance (w), a model 9 provided in an adaptive control part is operated with a controlled variable approximating a controlled variable (y) with which a plant 7 is operated. The controlled variable (y) and an output (yw) of the model 9 are compared with each other by a subtractor 11, and the parameter of the model 9 is so corrected by an adapting mechanism 13 that a difference delta between them approximates to zero. An internal variable 14 of the model 9, for example, the first-degree and high-degree differential values of the output (yw) of the model 9 are multiplied by a coefficient in a coefficient device 15, and the results are added to the output signal of a PI regulator 4 by an adder 6. Thus, a false differential value of the controlled variable (y) is fed back to the control system as a manipulated variable, and the control capacity for disturbance is improved.

Patent JP-H01236759-A (JP)
Title: Image reader
Inventor: NAKAJIMA AKIO
IPC: H04N1/40
Filed: 1988-03-16
Abstract: PURPOSE:To improve the convenience for use by providing a non-volatile storage means where the mode having the highest frequency in use is automatically stored and setting it as the default mode at the time of power-on. CONSTITUTION:At the time of power-on, the rise mode written in a non-volatile memory EEPROM 74 as a first storage means is read to perform initialization. A user inputs a command signal designated by himself to a CPU 42 to set the user registered default mode, and the frequency in use is stored in an attribute RAM 52 as a second nonvolatile storage means whose contents can be rewritten for each set value. First and second storage means are formed in independent areas of the ROM 74. Said frequency in use is counted up by one by a use frequency counting means to update stored contents, and the image read mode having the highest frequency in use is discriminated. This image read mode is changed and stored in the first storage means by a rise mode changing means. Thus, the rise mode is always set to the mode having the highest frequency in use, and an image is immediately read in the prescribed mode at the time of power-on to improve the convenience for use.

Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a small-sized ink jet head wide in a range of usable ink and capable of forming nozzles in high density and a recording apparatus using this ink jet head. SOLUTION: High frequency voltage pulses are applied to the crossing digital electrodes 2 of a piezoelectric substrate 1 and the piezoelectric substrate is mechanically distorted to generate surface elastic waves. By this constitution, vibration energy is directly emitted into ink from the crossing digital electrodes 2 and the generated surface elastic waves become leak Rayleigh's waves to further emit vibration energies of longitudinal waves into the ink. The synthesizing force of these vibration energies of longitudinal waves is the force in the direction crossing the surface of the piezoelectric substrate at a right angle.  A nozzle top plate 4 having nozzle orifice parts 5 in opposed relation to the crossing digital electrodes 2 is provided and vibration energy acts on the liquid surface of ink of each of the nozzle orifice parts 5 to emit ink liquid droplets from the nozzle orifice parts 5.

Abstract: PROBLEM TO BE SOLVED: To prevent sucking fault and to reduce an adverse effect on a floating characteristic due to dust, by providing continuous projections on a pair of continuous rails having a tapered surface on the end surface of an air inlet side and an electromagnetic transducer on the end surface of an air outlet side on an air bearing surface for generating a floating force. SOLUTION: The magnetic head slider 32 is constituted by providing a pair of rails 48 and 50 having tapered surfaces 48b and 50b in the end surface 32a of an air inlet side and an electromagnetic transducer 56 in the end surface 32b of an air outlet side. Further, on the rails 48 and 50, projections 52 and 54 of about 30nm in height are provided via an SiC layer as an adhesive layer made of a hard material thin layer and having a thickness of 5nm. Thus, positions of the generation of negative pressures are limited outside the air bearing surfaces 48a and 50a of the rails 48 and 50, and deposition of dusts is prevented. Therefore, a contact area between a disk and the magnetic head slider is reduced to prevent adsorption, and the reliability is increased.

Filed: 1983-04-13
Abstract: PURPOSE:To prevent washing steam from flowing out of a washing tank, by bringing solvent vapor into contact with a liquid curtain formed by flowing a cooled washing liquid downwardly. CONSTITUTION:A liquid curtain 16 is formed by downwardly flowing a cooled washing liquid introduced from a cooled liquid pipe 13 along fins 15. On the other hand, a compressed gas jet body 18 having jet orifices 17 opened toward the fins 15 is formed to the lower end of the passage 9 of an object 3 to be washed while compressed gas is injected to the fins 15 to forcibly flow solvent vapor toward the fins 15 and the liquid curtain 16 and the solvent vapor is brought into contact with the liquid curtain 16 to be condensed. In addition, the compressed gas injected from the jet orifices 17 is refluxed to the inflow pipe 22 in the jet body 18 from the discharge pipe 21 connected to the outside of a vapor washing tank 2 through a baffle plate 20 to be recirculated. As a result, the contact efficiency of the cooled washing liquid and washing vapor is extremely well while washing vapor is rapidly condensed and, therefore, said vapor is prevented from flowing out of the washing tank 2.

Filed: 1988-03-16
Abstract: PURPOSE:To suppress the unnecessary increase of the driving capacity of a first differential amplifying circuit by dividing a reed bus as the output of the first differential amplifying circuit for the first differential amplifying circuit and setting a driving capacity in accordance with the load of a divided reed bus to respective first differential amplifying circuits. CONSTITUTION:First differential amplifying circuits 10-13 are connected through respectively independent reed buses to a differential amplifying circuit 9. Here, for the reed bus having the largest load capacity in 4 blocks, the capacity is minimized for the part not connected to the first differential amplifying circuit of other block compared with the reed bus of a conventional semiconductor integrated circuit device. In addition, since for other block, the wiring length itself of the reed bus is shorter, for example, when the ratio of the capacity attended with the wiring of the read bus of respective blocks is 5:4:3:2, and the driving capacity of the first differential amplifying circuit of respective blocks may be also respectively 5:4:3:2. Thus, the unnecessary increase of the driving element of the first differential amplifying circuit is prevented and the energy consumption can be suppressed.
