Title: Production of transparent electrode
Inventor: AOYAMA JUNICHI
IPC: C09J5/00
Filed: 1990-10-04
Abstract: PURPOSE:To obtain transparent electrodes by bringing a substrate and the thin-film surface of a sheet formed with a transparent conductive thin film on a base into light contact with each other via an adhesive layer by photoirradiation and further subjecting the surface to the photoirradiation via a mask, then peeling the sheet to allow the thin films of prescribed patterns to remain on the substrate. CONSTITUTION:The way that the adhesive power of the adhesive layer used for tight contact of the substrate and the sheet is changed by the photoirradiation includes the way that the adhesive power is intensified by a photopolymn. or photocrosslinking reaction and the way that the adhesive power is weakened by a photodecomposition reaction according to the compsn. of the adhesive layer. The adhesive layers of both are separated by the photoirradiation to the part where the transparent conductive thin film has the strong adhesive power to the substrate and the part where the adhesive power of the transfer sheet to the base is strong. The thin film of the part where the adhesive power to the substrate is strong remains on the substrate and the thin film of the part where the adhesive power to the base is strong is peeled together with the transfer sheet at the time of peeling the transfer sheet, by which the transparent electrode patterns are formed.

Title: Solar energy driven radio controlled timepiece
Inventor: RUDOLF HOLGER
IPC: G04R20/00
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To prevent improper time indication of a radio controlled timepiece which occurs when energy stored in an electricity storing means becomes sufficient for buffering operations of a processor for controlling photoelectric display, but insufficient for surely operating a transducer for moving hands for maintaining proper time as getting nearer to the end of operations. SOLUTION: A solar energy driven radio controlled timepiece 11 has a possibility of causing improper time indication, because a pulse load disrupts operating voltage of the timepiece which is supplied from a buffer electricity storing means of a solar battery 22 and has already dropped down from a critical level for a very short time, before the operating voltage definitely drops down from the switching-off level and each pulse supplied to an electromechanical transducer 15 is not possible to advance a display any more.  When the interruption or cutting-off a drive pulse for moving hands for maintaining proper time is detected by means of a stepping monitor in this timepiece, the positions of the hands are automatically corrected to the positions for indicating the absolute time decoded from the present-time indicating telegram, by means of a radio-controlled processor by turning on the receiver of the timepiece by triggering a reset command.

Abstract: PURPOSE:To match a reference level of a video signal with high accuracy and also to increase only an intermediate brightness while keeping a white peak level as it is by applying nonlinear amplification to the video signal just after clamping the signal. CONSTITUTION:A video signal such as a luminance signal is inputted to a clamp circuit 2, in which a bottom level of the waveform is clamped to a voltage E0 of a DC voltage source 22 and the result is inputted to a nonlinear amplifier circuit 3. A diode 31 of the nonlinear amplifier circuit 3 is turned on when the voltage thereacross reaches a voltage higher than E1+Vf and the input signal is divided (attenuated) by resistors 32, 33 in this case and the resulting voltage is fed to an amplifier 5. With a high luminance video signal higher than the voltage E1+Vf inputted, since the signal voltage is divided by the resistors 32, 33, then it is attenuated, that is, a kind of limit state. The signal is amplified by the amplifier 5, then only the intermediate brightness level is increased while the white peak level (PMAX) is kept as it is.

IPC: G11B20/10
Filed: 1984-12-18
Abstract: PURPOSE:To prevent deterioration in performance by reading the value of a current rotational position, and judging whether a channel is connected or disconnected for processing from the read value. CONSTITUTION:A set sector tag is sent from a bus 11 connected to a controller and decoded by a tag decoder 1 to output a set target signal 14, and the sector number of a target record position is sent and set in a register 2 under the control of a gate G for the signal 14. The controller controls the G of a read current sector signal 15 outputted by the decoder 1 to send out the contents of a counter 3, thereby knowing the current position of a sector. Then, when n-5<=x<=n-2 where (x) is the read value and (n) is the target position, the end status of a set sector command is sent to a host to receive a next command; when not, the sector value of n-5 is sent to a disk device to release a connection. Consequently, an access time is shortened by one turn when a record is between n-5 and n-2.
