Title: Line terminating equipment
Inventor: FUKUDA SETSU
IPC: H04L5/14
Filed: 1987-03-18
Abstract: PURPOSE:To obtain a reproduced clock including the suppressed jitter by providing an echo inhibiting circuit between a comparator and a timing reproducing circuit to inhibit the output produced by the echo in the output of a comparator and to transmit only the output produced by a bipolar code. CONSTITUTION:An echo inhibiting circuit 16 is provided between a comparator 12 and a timing reproducing circuit 14. The circuit 16 contains AND gates G1 and G2 and a NOR gate G3 which form a selector. The switch signal of the selector is produced from the outputs Q and Q' of a D type flip-flop FF and the positive output OUTp and the negative output OUTn of the comparator 12 are used as the input signal of the selector. The FF uses the output of the gate G3 as a clock and its own output Q' as the data respectively. The input is inhibited to the circuit 14 for the output of echo of the comparator 12 produced by a bridged tap. Then the timing reproduction is attained only by the comparator output of a normal received signal (primary signal).

Title: Formation of fine pattern
Inventor: MATSUZAWA TOSHIHARU
IPC: H01L21/027
Filed: 1987-03-20
Abstract: PURPOSE:To enable more true transcription of images on desired rectangles, by using two kinds of photomasks so that a common region is formed into a desired shape by superposing the photomasks and performing two stages of exposure operations. CONSTITUTION:Latent images of photomask patterns, including desired patterns, are formed on an observed region with a photoresist by a first stage of exposure operation. If patterns (limited to light interrupting patterns) of these photomasks are desired beforehand to be larger than the desired patterns, no corner parts exist on a region (the inside of a rectangle) where the desired patterns should be replicated, and so no deterioration in resolution occur due to the existence of the corner parts. When a second stage of exposure succeeds to use a pattern (a rectangle perpendicular to and congruent with the patterns 5 used in the first stage) so that regions 7 common to the patterns 5 of the photomask used in the first stage of exposure are formed into desired patterns, resolution deterioration which is peculiar to the rectangular corner does not occur so that more true latent images can be formed into desired patterns (squares).

IPC: B65H29/58
Filed: 1983-04-12
Abstract: PURPOSE:To have quick reversing of copy sheets which requires a minor space, by furnishing a left and a right side gear meshing with a circular inner gear, by equipping each side gear with a pair of pinch rollers and a chute, and by rotating them. CONSTITUTION:Each sheet having passed between chutes 15, 15' is drawn by pinch rollers 11, 11' in the direction of the arrow. The trailing edge of this sheet is caught by a sensor 24, and a shaft 18 is turned 180 deg. to allow a plate 17' to depress a cam plate 23. Then a drive transmissive roller 27 is separated from drive rollers 31', 32' to stop the rotation in the state that pinch rollers 10, 10', 11, 11' pinch the trailing edge of the sheet. At the same time, side gears 8, 8', 9, 9' are rotated the in inner gear plates 7, 7' in the direction of the arrow, and when they turn 180 deg. and stop, the plate 17' stops pressing the cam plate 33 to cause restitution of links 26, 26'. Exhaustion is made in the state that the trailing edge is inverted by allowing the roller 27 to be in contact with the rollers 31, 32 to yield re-rotation. Thus inversion of each sheet can be made using a small space.

Abstract: PURPOSE:To facilitate the maintenance, the diagnosis, and the debugging processing of a device to be observed, by starting the tracing operation when a preliminarily set condition is detected and continuing the tracing opration for a preliminarily set certain time. CONSTITUTION:When the trace start condition is detected by a trace start condition detecting circuit 150, a controlling circuit 120 initializes a counting circuit 160 and prepares for the start of the tracing opration. Hereafter, each time the trace condition is detected by a trace condition detecting circuit 110, contents of an address register 140 and the circuit 160 are increased by one and updated. Simultaneously, state information from the device to be observed is written in the address, which is designated by a register 140, of a storage circuit 130. When the value of the circuit 160 reaches a certain value, the circuit 120 suppresses immediately the generation of the write signal to the circuit 130 and stops the update of contents of the register 140 to terminate the tracing operation. Thereafter, each time the trace start condition is detected, said operation is repeated.

Abstract: PROBLEM TO BE SOLVED: To efficiently control to drive by driving a motor based on direction information by a driving means. SOLUTION: A substracter 14 subtracts a speed command value ωrcom from a rotor angular velocity rω, and outputs information of speed difference to a speed controller 6. The controller 6 regulates a q-axis current command value 11qcom so that the angular velocity ωr of the rotor of a motor 1 becomes a value ωrcom. A substracter 12 subtracts the q-axis current command value 11qcom received from the controller 6 from q-axis current from a 3 phase-2 phase converter 4 to obtain their difference, and outputs the difference information to a q-axis current controller 7. The controller 7 regulates a value of an output voltage V1q output to a 2 phase-3 phase converter 8 based on the difference information.  The current component actually output from an inverter 9 can be controlled to coincide with the current command value 11qcom output from the controller 6 by this regulation.

Filed: 1989-03-16
Abstract: PURPOSE:To obtain superior integrated gain characteristic by sending a gain error due to the operating resistance of an analog switch included in a feed back resistor to the output side of an operational amplifier via a reverse amplifier. CONSTITUTION:The connecting point of the resistors R9 and R10 is connected to the (+) input side of the operational amplifier OP3 having a function to erase an error voltage. Also, the output side of the operational amplifier OP1 is connected to the (-) input side of the operational amplifier OP3 via a resistor R7, and the (-) input side is connected to the output side with a resistor R6. The resistor R7 is the input resistor of the operational amplifier OP3. An output voltage V02 is outputted between terminals T3 and T4, and since the output voltage V02 is the one in which an input voltage Vi inputted from between terminals T1 and T2 is amplified to a preset gain by the operational amplifier OP3, the error voltage due to the operating resistance of the analog switch can be eliminated. Thereby, it is possible to eliminate an uncertain element for a variable gain step, and to vary an amplification factor with the preset gain.
