Title: Detecting method for chattering in cold rolling mill
Inventor: FUNATOKO ISOO
IPC: B21B33/00
Filed: 1985-07-05
Abstract: PURPOSE:To improve the detecting accuracy by passing signals from a vibratory speed sensor equipped on a housing of a cold rolling mill through a band-pass filter of a natural frequency of the rolling mill to detect a chattering by said output signal. CONSTITUTION:A vibratory speed sensor 2 of the horizontal direction is equipped on the housing of the rolling mill. Then, the vibratory wave from the vibration sensor 2 is amplified by an amplifier 3 and the amplified signals are passed through the band-pass filter 4 of the natural frequency of the mill. This is performed because the chattering is noticed to cause in the frequency band of natural vibration of the mill. The signal filtrated by the band-pass filter 4 is rectified by a rectifying circuit 5 and after smoothed by a smoothing circuit 6, fed to an arithmetic circuit 7, then the digitized chattering vibratory signal is collected with a previously set reference value and then an alarm or an automatic decelerating command is issued.

Title: Filter circuit device
Inventor: IKEDA MASAO
IPC: H03H7/06
Filed: 1978-11-27
Abstract: PURPOSE:To obtain a filter featuring the variably frequency of the inflection point by securing the variable control voltage to be applied to the element in the circuit network containing the variable capacity element. CONSTITUTION:Capacitor C1 is set to the capacity which can be ignored serially to varicap CD in the circuit network comprising varicap CD functioning as the variable capacity element, capacitor C1 and resistance Rn(n=1-4). And DC voltage VBC which is applied to varicap CD through resistance R3 is made variable, and thus the capacity of CD varies. Thus the frequency of the inflection point varies for HPF. For LPF too, the frequency of the inflection point can be varied by varying voltage VBC. For the variable power source of VBC, the frequency showing the inflection point is indicated to control input end 6 of microcomputer mu-COM5. As a result, the digital signal corresponding to the frequency is delivered through mu-COM5 and then converted into DC voltage VBE through D/A converter 4 to be applied to varicap CD. Thus a filter featuring the desired inflection point frequency can be obtained.

Title: Platen roll
Inventor: KANARI SHOHEI
IPC: B41J11/053
Filed: 1987-06-15
Abstract: PURPOSE:To reduce a noise to a great extent with a low production cost, by a method wherein, a metal cylinder has a double tube construction made of an outer tube and an inner tube, and a space part having a specific dimension is provided in the interface between the outer tube and the inner tube. CONSTITUTION:A metal cylinder used for a platen roll has a double tube construction made of an outer tube 5 and an inner tube 6 with a space part 7 in the interface. The periphery of the double metal tube is coated with a high- hardness rubber layer, and bearings and shafts are mounted on both ends of the metal tube. The space part 7 acts to damp an energy when being subjected to vibration from the high-hardness rubber layer, thus exhibiting a good vibration-damping properties. The space part 7 having a gap (d) more than 100mum is undesirable because it results in a loose nesting of the outer tube 5 to the inner tube 6. When the tubes were mechanically coupled by cold drawing, a noise control effect superior to a conventional platen roll is realized with a gap (d) of 20mum or more.

Title: Transmission type electron microscope
Inventor: HAYASHI SOICHIRO
IPC: G06F3/048
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To permit mouse operation even when looking away from an operating image plane by enlarging the image plane occupying area of an operating image plane switch of a console image plane assigned by a cursor of a mouse. SOLUTION: The area of an image plane switch 8 remains the same, but the area of a composite area switch 3 is enlarged. Even when looking away from a console of a personal computer, the cursor tip of a mouse does not come off the composite area switch 3, and this facilitates the operation of the mouse. A switch part of the composite area switch 3 is trisected in low speed(LOW), medium speed(MID) and high speed(HIGH) to change the moving speed of an XY stage. An area switch 31 permits the simultaneous operation of direction instruction and high speed instruction to the XY stage. The composite area switch 3 can also be divided plurally in angles in a vector direction for vector movement. This constitution is ideal for remote operation of a device such as a transmission type electron microscope operated to observe by moving a sample set on the XY stage.

Title: Data transmission circuit
Inventor: MIURA NORIHISA
IPC: H04L5/22
Filed: 1988-06-15
Abstract: PURPOSE:To send a normal data from other transmission circuit in the event of occurrence of a fault of the transmission circuit by fixing an output of the transmission circuit in the open state when a data sending an L level is fed to an output part of a data transmission circuit. CONSTITUTION:If a transmission timing of a channel CH1 data is deviated, an H level is outputted from an OR gate 31 and a *Q terminal of a DFF 32 is fixed to an L level. Then an AND gate 21 is always reset and an output transistor(TR) 41 is kept in the off-state and the CH1 data is not outputted to a data bus 8. Moreover, even with a CH 1 start pulse given, since the output at the Q terminal of the DFF 32 is fixed to an H, the D terminal goes to an H level and the output of the *Q terminal remains at an L. Thus, the AND gate 21 remains at a reset and no fault data is sent to the data bus. That is, even with a fault in the CH 1 data transmission circuit caused, a normal data is sent from the data transmission circuit of CH2.

Abstract: PURPOSE:To obtain the title cable coated with a highly foamed and uniform insulating material without being eccentric by keeping the inner diameter of a through hole of a nipple to which a conductor is lead and the outer diameter of the conductor within a prescribed relation. CONSTITUTION:The inner diameter d1 of a through hole of a nipple 2 to which a conductor 1 is lead and the outer diameter d2 of the conductor 1 is kept in a relation of d1<=d2, and an insulator 4 is formed on the outer surrounding of the conductor passed through the hole of the nipple 2 by extrusion. Since the inner diameter d1 of the through hole of the nipple is the same as or smaller than the outer diameter d2 of the conductor, a gap is not formed between the inner diameter d1 and the diameter d2 and thus gas leakage is prevented and a highly foamed insulator 4 is obtained. Also, since no gap between the inner diameter d1 and the outer diameter d2, the conductor is prevented from slight bending and switching, and as a result the conductor is prevented from becoming eccentric and coated with the foamed insulator 4 uniformly.
