Title: Corrected gradation curve generator
Inventor: HAYASHI KOJI
IPC: H04N1/407
Filed: 1994-01-27
Abstract: PURPOSE:To generate a detailed smooth recording image by using a digital filter so as to apply smoothing processing to a corrected gradation curve when a discontinuous gap is formed in the case of digital display of the corrected gradation curve. CONSTITUTION:A corrected gradation curve characteristic conversion processing is implemented to apply characteristic conversion processing to a corrected gradation curve and a digital filter in use is selected by the operation of an operation section. Then the selected digital filter is used to apply smoothing processing to the corrected gradation curve. Thus, number of gradation jump of output gradation is reduced by comparing a conversion table giving a corrected gradation curve E2 before smoothing processing with a conversion table giving a corrected gradation curve E3 after smoothing. Furthermore, When the digital filtering is more intensified, smoothing processing is applied to the corrected gradation curve with a larger spatial period and a conversion table providing a characteristic conversion gradation curve E4 is obtained. Thus, the jump gradation number in an output gradation is further reduced.

Title: Chip inductor
Inventor: KIGOSHI YASUSHI
IPC: H01F27/29
Filed: 1983-01-19
Abstract: PURPOSE:To permit baking in the air and obtain mechanical strength sufficiently high so that a wire can be properly wound on a magnetic member, by employing as the wire for a chip inductor an alloy wire including a specific amount of Al and the balance Cu. CONSTITUTION:A coiled conductor is buried in a sintered magnetic member. Electrodes 17 are respectively formed on the opposing end surfaces of the sintered magnetic member. As the conductor, a wire is employed which is made of an alloy consisting essentially of 3-8wt% Al and the balance Cu. Thus, it is possible to provide the wire with resistance to oxidation and mechanical strength sufficiently high so that the wire can endure the tensile stress generated when wound on the magnetic member. An Al content less than 3wt% reduces the amount of Al2O3 formed on the surface by admixture with Al, so that the wire would be easily oxidized and consequently disconnected or deteriorated in conductivity, which makes impossible to obtain a desired Q value. On the other hand, an Al content in excess of 8wt% increases the hardness of the alloy thereby it would be difficult to form the alloy into a wire.

Title: Information processor
Inventor: FUJITA SHIGERU
IPC: G06F3/041
Filed: 1994-01-27
Abstract: PURPOSE:To suppress the electromagnetic interference for an information processor with no increase of its cost by securing the electrical connection between the ground of a shielding plate placed on the rear of a coordinate detection means and the ground of this detector means. CONSTITUTION:The connection is secured among the ground of liquid crystal display unit L3, the ground of a tablet sensor (coordinate detector) L4, an electromagnetic shielding plate L5, and the ground layer L11 of a main substrate respectively. In such a constitution, the ground surface drawn out up to the main substrate surface L7 from the layer L11 touches a casing mold L1 when this mold is fixed by a screw. In other words, the electromagnetic nozzle led from the main substrate is surrounded by the ground surfaces connected together in common. Thus the electromagnetic nozzle can be effectively cut. In such a way, the electromagnetic interference can be suppressed with no increase of cost for an information processor.

Filed: 1990-01-17
Abstract: PURPOSE:To improve the operation stability when a high output voltage is extracted to apply to a load circuit having low impedance by providing an impedance conversion circuit with high input impedance and low output impedance between a voltage increase circuit and an output terminal. CONSTITUTION:An impedance conversion circuit 4 with high input impedance and low output impedance is provided between a voltage increase circuit 3 and an output terminal.

Thus, the operation stability when a high output voltage is extracted to apply to a load circuit 5 having low impedance is improved.

Title: Compressing circuit
Inventor: ADACHI TOSHIO
IPC: H03G7/00
Filed: 1988-01-21
Abstract: PURPOSE:To prevent the input/output characteristic from being dispersed depending on the characteristic of components by using a characteristic of a linear operating region of a MOS transistor(TR) in place of a resistor having been in use for a conventional root compression circuit. CONSTITUTION:Since the drain and gate of the 1st N-channel MOS TR 11 are made short, the TR is operated in the saturation region and a current Iin flowing from an input terminal 13 to a terminal 15 is given by equation I, where Vth is a threshold voltage of the N-channel MOS TR 11, W1 is a channel width, L1 is the length of channel, K' is a gain coefficient and VCOM is a potential at an input terminal 16. On the other hand, let the input voltage of the circuit be Vin, the current Iin flowing from the input terminal 13 toward the terminal 15 is given by equation II since a MOS TR 22 is operated in a linear region. When a gate-source voltage Vgs is sufficiently larger than the drain-source voltage (Vin-VCOM), the equation II is approximated as equation II'. Since the relation of Iin=-Iout exists, equation III is introduced. Thus, the parameter K' depending on the process is erased.
