Title: Method of manufacturing printed-wiring board
Inventor: INOUE WAKANA
IPC: G03G13/26
Filed: 1993-08-25
Abstract: PURPOSE:To realize the circuit pattern having high resolving power by a method wherein a photoconductive composition containing a binding resin and a photoconductive compound is manufactured by polymerizing the bonding resin in a solution containing the dispersed photoconductive compound to obtain even photoconductive layers. CONSTITUTION:A photoconductive composition is composed of at least a binding resin and a photoconductive compound while the binding resin polymerized in a solution containing the dispersed photoconductive compound shall bear the electrophotographic characteristics including the charging capacity, etc., as well as the solubility in an alkaline solution. Furthermore, since the metallic conductive layer in a non-picture image part shall be etched in an acidic solution, a resin having anionic functional group is especially used to attain the etching resistance while the composition of the binding resin is properly adjusted by copolymerizing an anionic monomer with a non-ionic monomer. Accordingly, even photoconductive layer can be provided on a conductive substrate using the photoconductive composition thereby enabling the title printed-wiring board having evident wiring patten to be realized.

Title: Superconductive magnetic recording method
Inventor: KOJIMA KAZUYOSHI
IPC: G11B9/00
Filed: 1987-08-25
Abstract: PURPOSE:To enable magnetic recording even if a magnetic material is not used and high-density recording can be executed by heating up thin superconductive films transiently up to the superconductive transition temp. or above in bit unit and making magnetic recording in the heated up this superconductive films. CONSTITUTION:The substrate on which the thin superconductive films are formed by dividing the same by each bit is put in a magnetic field and the thin superconductive films are transiently heated up to the superconduction transition temp. or above in bit units to capture magnetic fluxes into the heated up thin superconductive films, by which the magnetic recording is executed. Namely, the magnetic fluxes are captured when said thin films re heated up to the superconduction transition temp. or above in the magnetic field and, therefore, the magnetic recording is executed. For example, a superconductive magnetic recorder is placed in the magnetic field and a laser beam 10 is projected on the bits having the thin superconductive films 2 to heat up the films up to the superconduction transition temp. or above. The magnetic fluxes are then taken into the heated up bits and are magnetically recorded.

Title: Ghost elimination device and ghost elimination method
Inventor: IGA HIROYUKI
IPC: H04N5/21
Filed: 1989-08-17
Abstract: PURPOSE:To reduce the low frequency fluctuation such as flicker due to the effect of a noise signal by detecting a tap coefficient of a prescribed level or over when a waveform equalizing processing to eliminate ghost reaches an equilibrium and correcting only the tap coefficient. CONSTITUTION:Whether or not the waveform equalizing processing reaches an equilibrium in a waveform equalizing loop is discriminated and when the equilibrium is reached, a microprocessor 31 detects a tap coefficient whose absolute value is a prescribed value or over and only the tap coefficient of a prescribed value or over is corrected. Moreover, whether or not the waveform equalizing processing reaches an equilibrium is discriminated depending whether the waveform equalizing number reaches a prescribed number. Thus, a flicker state low frequency fluctuation due to a noise signal fed to a reference signal for ghost elimination is reduced without stopping the waveform equalizing loop.

Title: Constant voltage generating circuit
Inventor: NAGATA KYOICHI
IPC: H01L21/822
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To provide the constant voltage generating circuit which sets the input voltage to a current mirror amplifier to an optimum level and does not increase chip area.

Filed: 1990-08-09
Abstract: PURPOSE:To accelerate reception processing by providing a reception data managing mechanism, and deciding the feasibility/infeasibility of data reception from another computer by inquiring for the mechanism by a communication processing mechanism. CONSTITUTION:The communication processing mechanism 70 inquires for the null state of a reception buffer area 40 for inter-computer communication to the reception data managing mechanism 20 when receiving a data transmission request from another computer. When it is judged that data reception is feasible, transmitted data is transferred to and stored in the reception buffer area 40 for inter-computer communication. Thence, after data transfer being completed, the reception data managing mechanism 20 receiving the above information updates managing information, and also, informs the storage of the data in the buffer area 40 for communication to the communication managing means 50 of a host computer. The communication managing means 50 performs the reception processing by reading out stored data. Thereby, the operation of the communication processing mechanism is separated from that of the host computer, which enables parallel operations to be performed and accelerates the reception processing.
