Title: Printed wiring board
Inventor: YOKOYAMA KEISUKE
IPC: H05K1/02
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To use no ferrite beads and realize cost reduction, by providing a printed board with lands at specific intervals, which connect first and second silver through holes filled with silver internally. SOLUTION: An analog earth terminal 1 is pierced by a penetrating hole in the vicinity of a digital earth terminal 2, and a digital earth terminal 2 by a penetrating hole in the vicinity of the analog earth terminal 1. The holes are filled with silver to form silver through holes 3a, 3b. On the back of a printed board 4, the silver through holes 3a and 3b are connected with each other through a land 5, so that the analog earth terminal 1 and the digital earth terminal 2 are mutually isolated. The impedances of the silver through holes increase in high frequency, so that the same effect as ferrite beads can be obtained. Thereby earth isolation of an analog circuit and a digital circuit can be realized without using expensive ferrite beads.

Filed: 1990-09-20
Abstract: PURPOSE:To make it possible to detect the presense or absence of even a relatively light material continuously with a simple constitution by applying a load which is received with a probe against the mutual repelling forces of first and second magnets, and detecting the descent of the second magnet. CONSTITUTION:A rod-shaped prove 4 made of synthetic resin is attached to a lid 12 of a main body 1 so that the probe can be moved up and down without resistance in a hole 12a. A magnet 5 is attached to the lower end part of the probe 4 so as to face a magnet 3 which is fixed to the inner bottom part of a cavity part so that the polarizing directions are opposite and the magnets repelled to each other. A roller made of synthetic resin 41 is rotatably attached to the head part of the probe 4. A product such as a semiconductor water is moved with the roller 41 being rotated. At this time, the probe 4 is pushed down against the repelling force of the magnets 3 and 5. Therefore, the interval between the magnets 3 and 5 is narrowed. A laser light emitting source 81 and a photodetector 82 are correspondingly attached to the side wall of a case body 11 by way of through holes 11a and 11b. When the probe 4 receives the load of the product, the light beam from the light emitting source 81 is shielded by the lowering of the magnet 5, and the output is guided out of an output terminal.

Filed: 1990-09-19
Abstract: PURPOSE:To make a signal gain high by allowing a monitor means to find the intensity of input signal light demultiplexed by a demultiplexing means from the output signal of an optical fiber and then perform control over the signal gain corresponding to the found light intensity. CONSTITUTION:When the input signal light inputted to an input port 10 varies in intensity, the monitor circuit 16 detects the intensity of the exciting light from the exciting light component inputted through the demultiplexer 14 and outputs it to a control circuit 17. The control circuit 17 controls an exciting light source 12 corresponding to the variation in the exciting light component intensity to vary the gain of optical amplification and controls the intensity of the output signal light outputted to an output port 15 through the demultiplexer 14 to a specific value. Thus, the gain control type optical fiber amplifier finds the intensity of the exciting light component demultiplexed by the demultiplexer 14 by the monitor circuit 16 and controls the signal gain according to the exciting light component intensity. Consequently, the signal gain is made high.

Title: Automatic document feeder and image forming device provided therewith
Inventor: HIROI MASAKAZU
IPC: B65H29/16
Filed: 1995-09-28
Abstract: PURPOSE: To restrain noise and vibration in an automatic document feeder in a counting mode. CONSTITUTION: In the counting mode in which a document P is counted, the document P is carried in a roughly reading mode, and carried without being stopped at a reading position (or in the minimum stopping time even if the document is stopped). Thus, the noise and the vibration in the feeder are restrained by consecutively carrying the document P without stopping the carrying means F1 and F2 (or in the shortest stopping time). In the counting mode, the document P is carried in the roughly reading mode which is as high speed as the device can, thereby shortening the circulating time of the document P.

IPC: G01H17/00
Filed: 1990-09-25
Abstract: PURPOSE:To precisely grasp an abnormal tendency in rotation shaft vibration of a rotating machine to prevent an accident to occur by averaging the vibrating characteristic data showing the relation between the rotating speed and amplitude value of the rotating machine every determined period to form elapsed time data. CONSTITUTION:When formation of elapsed time data is requested, elapsed time data formation start is instructed to an arithmetic processing part 64. In the arithmetic processing part 64, arithmetic processing for subtracting the vibration characteristic data forming a past standard designated by the start request from the vibration characteristic data taken out from a characteristic data memory part 65 is conducted. Thus, by computing the difference between the both, the deterioration degree of a turbine rotating shaft can be clearly found when the data is displayed. Further, the arithmetic result is summed in respective elapsed units of one week, one month and one year, and the resulting result is averaged. This arithmetic processing data is stored in an elapsed time data memory part 68 as the elapsed time data, and displayed on a CRT 67 as occasion demands.
