Title: Phase synchronizing oscillation circuit
Inventor: EKUSA RYOICHI
IPC: H03L7/06
Filed: 1990-10-31
Abstract: PURPOSE:To decrease the frequency of switching by judging jitters on a transmission line in a real time and performing switching operation with the phase synchronizing oscillation circuit which performs switching to the other transmission line when the clock phase of an arrival signal exceeds a permissible phase difference CONSTITUTION:The phase difference signal (c) outputted by a phase comparator 4 which inputs the clock signal (a) extracted by a frequency divider 3 from the signal on a transmission line selected by a transmission line sensor 11 and the synchronous clock signal (b) from a synchronizing clock generator 2 is inputted as a gate signal to an AND gate 5. While the phase difference signal (c) is outputted, a counter 7 counts the high-speed clock signal (d) from a high- speed clock generator 6 and sets a flip-flop 9 when a value which is set previously so as to allow jitter components is exceeded, and the value of a counter increases by one. A counter 8 resets the flip-flop 9 and counter 7 at a period nearly equal to the period of the synchronous clock signal (b). The number of jitter generating circuits which can not be permitted by the counter 10 is counted by the operation and its output (i) is used as a transmission selection factor of a transmission line selection controller 11.

Title: Pen-type input device
Inventor: SATO YASUHIRO
IPC: G06F3/038
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To precisely detect the moving direction and the moving amount of a pen tip by suppressing the detection error of an initial inclined angle becoming the reference of inclined angle detection at the time of detecting writing. SOLUTION: An initial inclined angle operation part 45 operates the initial inclined angle of a pen axis based on signals from acceleration sensors 2a-2c in a still state. An inputting inclined angle change operation part 47 operates the inclined angle of the pen axis based on the operated value of the initial inclined angle and the subsequent change of the inclined angle. A coordinate conversion operation part 48 converts a coordinate into the acceleration of a coordinate system based on the operated inclined angle. An initial inclined angle correction part 51 corrects the operation value of the initial inclined angle and sets the integrated value of acceleration in the still state where coordinate conversion is executed to be zero. A moving amount operation part 55 operates the moving amount of the pen tip based on acceleration during writing, which is coordinate-converted.

Abstract: PROBLEM TO BE SOLVED: To measure the shape of a steel strip which is run while the strip is rolled under tension without scratching the strip nor receiving any influence from residual magnetization by impressing an alternating magnetic field upon the strip and installing a plurality of sensors at regular intervals in the width direction of the strip. SOLUTION: In order to find the stress of a steel strip 1 which is run between an un-coiler 5 and coiler 7 while the strip 1 is rolled with working rolls 6, a magnetic field impressing device 2 which impresses an alternating magnetic field upon the strip 1 and a plurality of sensors 4 which are arranged in the width direction of the strip 1 and composed of Barkhausen noise detectors 3 are provided. In addition, holding rolls 8 are provided so as to prevent the occurrence of bending stresses caused by the deflection of the strip. Since a noise-stress converting device and an elongation display 9 connected to the sensors 4 are connected to the working rolls 6, data can be fed back to the rolling line.  By finding the amount of noise by means of the sensors 4 and the tension distribution or elongation distribution on the strip 1 from the previously found relation between the amount of noise and tension and changing the rolling condition, a prescribed shape is obtained.

Abstract: PURPOSE:To form a semiconductor device of high S/N ratio by by-passing positive holes to be injected to a power supply voltage via a P-type polycrystalline Si layer and an N<+> type diffusion layer when noise and the like of voltage higher than the power supply voltage are inputted. CONSTITUTION:When noise and the like of voltage higher than a power supply voltage VDD are inputted from an input terminal 54, a PN junction constituted of a P<+> type polycrystalline Si layer 100 and an N<+> type diffusion layer 101 is biased in the forward direction. Hence positive holes are injected from the layer 100 to the layer 101; the positive holes recombine with electrons in the layer 101, and the most of them vanish; the residual holes are injected into a P-type well 102, reach a P<+> type diffusion layer 103, and are by-passed to the power supply voltage VDD. Some part of the positive holes reach the vicinity of the junction surface between the well 102 and a substrate 41, but are repelled to the p-type well by a built-in electric field generated in a depletion layer. As a result, the positive holes are by-passed to the power supply voltage VDD via the layers 101, 102. Thereby noise higher than the voltage VDD is by-passed to the voltage VDD.

Abstract: PURPOSE:To provide photosensitive material processing device constituted to improve a property to transport negative films. CONSTITUTION:A cartridge packing section 34 of an automatic developing device is provided with a cutter 44 for cutting the front end of the negative film 12 drawn out of a cartridge. This cutter cuts the front end of the negative film to be sent to a processing section in such a manner that one end in the width direction projects from the intermediate part between guide grooves 60A, 60B. As a result, the negative film is so guided along these guide grooves that the front end 68 at one end of the transverse direction thereof leads. The bulging amt. of the intermediate part in the curving part of the transporting path is thus suppressed and the bending or turned up of the film by contact with a roller does not arise.
