Title: Integrated optical unit
Inventor: YAMAMIYA KUNIO
IPC: G11B7/095
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To deal with integration by constituting the movement of a parallel plate glass for correcting spherical aberration with precision required by an optical system and in a small size. SOLUTION: If an optical disk 6 is one with a substrate thickness of 0.6mm, an electric current is flowed in a driving coil 15 so that a parallel plate glass 9a is positioned over the optical axis of a light beam; if the optical disk 6 is one with a substrate thickness of 1.2mm, a reverse current is allowed to flow through the driving coil 15 so that a parallel plate glass 9b is positioned over the optical axis of the light beam. Consequently, a rotor 9 is rotatably moved by an interaction between the generated magnetic field of the driving coil 15 and the magnetization of a permanent magnet 17.

Title: Method for fitting current-voltage characteristics of semiconductor element and electronic circuit
Inventor: KIMURA MUTSUMI
IPC: H01L21/82
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To realize fitting with high accuracy, free from vibrations by transforming discrete current values to discrete transformed values by a transformation function, by performing fitting to obtain a continuos transformed value, and then inversely transforming the continuos transformed value to a continuos current value by an inverse transformation function. SOLUTION: Discrete current values 2 are transformed by a transformation function y=f(x) (step 3) to obtain discrete transformed values 4. A spline function fitting is performed (step 5) for the discrete transformed values to obtain a continuous transformed value 6. Then, the continuous transformed value 6 is inversely transformed (step 7) by an inverse transformation function x=g(y) with respect to the transformation function y=f(x) to obtain a continuous current value 8. This can prevent vibrations between discrete current values obtained by measurement, simulation, or other method, and realize fitting with high accuracy in a wide range from a small current value to a large current value even if the dynamic range of the current values is wide.

Title: Image reading device and image forming device
Inventor: YOSHIDA AKIMARO
IPC: G03B27/62
Filed: 1988-03-14
Abstract: PURPOSE:To eliminate unrequired original reading or image forming by controlling the scanning range of an image reading means by a reading control means based on the size of an original placed in a prescribed position on a platen so that the original alone is scanned. CONSTITUTION:The title devices are provided with the image reading means 131 performing the image reading of the original 2 placed in the prescribed position by the scanning of an exposure means 103. The original feeding outlet of an original feeding means is located in a first position rear to the prescribed position on the platen 101. A first original is fed and placed in the prescribed position and then carried to a downstream position that is a third position adjacent to the prescribed position after reading is finished, while a second original is fed and placed in the prescribed position. This procedure is repeated for a third and succeeding originals. During this continual feeding operation, a part not forming an image is formed on the platen 101 without changing a normal image scanning method. Time loss due to replacing the original is thereby minimized constantly regardless of size, and an unrequired image can be eliminated.

Title: Correction of irregularities of fuel controlling amount by engine cylinders
Inventor: MATSUMURA TOSHIMI
IPC: F02D45/00
Filed: 1982-04-09
Abstract: PURPOSE:To make it possible to correct the amount of fuel injection by cylinders by a method wherein in the case of a fuel injection device for an internal- combustion engine, the amount of fuel injection by cylinders is corrected in proportion to the difference between the average engine rotation speed and the engine rotation speed corresponding to each of the cylinders. CONSTITUTION:When the amount (e) of fuel injection by cylinders becomes irregular as a result of irregularities of the surface areas of the openings of fuel injection valves among the cylinders occurring due to a manufacturing tolerance or a secular change, the engine rotation speed becomes irregular as shown by the left hand side graph (a). To overcome such difficulties, a study amount K1 is first obtained on the base of the difference between the average value N of the engine rotation speed and the actual engine rotation speed N1 as shown by the right hand side graph (c) and then the fuel controlling amount T1 is corrected for each of the cylinders as shown by the right hand side graph (d). As a consequence, the amount (q1) of fuel supply becomes equal for each of the cylinders as shown by the graph (e).

Title: Mobile terminal
Inventor: OTERU YOICHI
IPC: H04B7/26
Filed: 1992-03-18
Abstract: PURPOSE:To improve the communication quality of a mobile terminal while moving, which communicates with plural base stations, and operates the communication by an encoded voice signal, accompanied with the movement in a communication. CONSTITUTION:When a reception level value R1 becomes less than a normal value H1 while a mobile terminal 10 operates the communication through a base station 21, the communication channel is maintained, and a base station 22 whose reception level value R2 is the maximum is selected. Then, the communication channel through the base station 22 is constituted with double- connection with a trunk circuit 33 in constituting a communication path by an exchange control station 30. When either of the two level values R1 and R2 exceeds the other normal value H2 (H2>H1), a means which release one of the double communication paths releases the communication channel whose level value is smaller as the end of the communication. Therefore, the mobile terminal simultaneously operates the communication through the communication channels with the two different base stations, so that even when an abnormal level drop or instantaneous interruption is generated at one base station, the communication can be saved by the other base station.
