Title: Encoding system of facsimile signal
Inventor: MIHASHI YOSHIYUKI
IPC: H04N1/40
Filed: 1982-06-25
Abstract: PURPOSE:To prevent a noise from being mixed due to an uneven luminous intensity, etc. of a light source, and to reproduce a good picture, by correcting a signal encoded by scanning an original, by use of a value of a reference signal read out of a storage part, and outputting the corrected value as a code. CONSTITUTION:A reference pattern corresponding to lines which are all white and black is added onto the same plane as an original. Immediately before scanning is started, a photoelectric converting output signal 5 obtained by scanning this pattern is digitized by an A/D converting part 1, and is stored in white and black line reference level signal storage parts 2 and 3, respectively. Thereafter, scanning of the original is started. The signal 5 obtained by scanning the original is also digitized in the same way, and this signal 6 is inputted to a multilevel encoding part 4. In said part, in accordance with picture element position information being in the course of scanning of this input signal, white and black reference levels corresponding to the same picture element position are read out of the storage part 2 and 3, and the input signal is encoded by use of said level, and code information 7 is outputted.

Title: Tracking device for rotary magnetic recording medium
Inventor: NAKAGAWA MITSUHISA
IPC: G11B21/08
Filed: 1983-06-20
Abstract: PURPOSE:To attain an access to a desired track in high speed and high accuracy by driving a DC motor with a pulse having the width corresponding to a shift amount to detect a head position error and reading the correction pulse width corresponding to the position error and a relative shift amount ratio out of a memory to correct the head position. CONSTITUTION:A pulse having the width corresponding to the relative shift amount to a track selected by a track selection control part 200 at a tracking control function part of a CPU is applied to a DC motor as a driving pulse. Then a head is shifted approximately to the position of the corresponding track via a head shift control part 202. A head position detecting part 204 detects a position error based on a reproduction pilot signal given from said track. An ROM address calculating part 206 calculates a relative distance ratio to the position error, and this calculated value is turned into an address to give an access to an ROM156. Then the correction drive pulse width is decided with no influence given to the control characteristics, the torque variation, etc. Thus the head position is corrected. Then an access is possible to a desired track in high speed and high accuracy.

Title: Tracking servo device
Inventor: HIRANO HIROYUKI
IPC: G11B7/085
Filed: 1982-06-25
Abstract: PURPOSE:To ensure a stable jumping action regardless of the eccentric degree of a recording track, by superposing a jump driving signal on a signal which eliminates approximately the resetting force when the tracking servo loop of an actuator is cut off. CONSTITUTION:A holding capacitor 19 is provided between a signal line and an earth and also between a servo loop switch 9a and an amplifier 10. Then the capacitor 19 holds a tracking error signal obtained right before the switch 9 is turned off. The switch 9 is turned off in response to a jump command, and the servo loop is cut off. In this case, the servo error signal is held by the cpacitor 19 immediately before the servo loop is cut off. Therefore an error signal obtained right before the servo loop is cut off is applied approximately as it is to a coil 11 which functions as an actuator. This process eliminates the resetting force to the middle point of a tracking mirror 12. At the same time, a jump driving signal given from a jump driving circuit 18 is superposed on a holding output. Thus the actuator is driven to perform a jumping action.

Title: Method and apparatus for forming fiber sheet by air flow route
Inventor: DUPONT JEAN-LOUIS
IPC: D01G15/46
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To obtain a regular fiber flow by an air flow 'air lay' and a uniform fiber sheet. SOLUTION: While fibers loosened by an air flow are dispersed and projected on a face 7a for formation-transportation, the fibers are subjected to a card operation before the fibers are introduced into the air flow to form a fiber sheet V on the face 7a by an air flow route. The fiber flow is made more regular by one or plural regular systems 5 between the card operation and the introduction of the fibers into the air flow.  In one of example forms, the regular system 5 is equipped with at least one comb type first cylinder 5a, the cylinder is installed so that the cylinder is rotated and driven at a peripheral speed strictly lower than that of a card cylinder 4h in a rotation direction opposite to that of the card cylinder 4h and the peripheral part of the first cylinder is covered with a lining having teeth or needles orientated in the backward direction, namely in the direction opposite to the rotation direction.

Title: Remote supervising system
Inventor: YONAHARA YOSHIHIDE
IPC: H02J13/00
Filed: 1987-05-02
Abstract: PURPOSE:To prevent an electric shock accident at the time of a connection test by connecting a light emitting element and a current restriction element which restricts current flowing to the light emitting element between an arrester and an earth and simultaneously providing a short-circuit means in parallel with the light emitting element and the current restriction element. CONSTITUTION:Between a node N1 and a node N2, a serially connected diode 35-1 and the light emitting element 36-1, a serially connected diode 35-2 and the light emitting element 36-2 are connected in parallel. For example, when the high voltage of AC 200V is impressed between a terminal 41-3 and the earth by mis-operation or by accident at the side of a supervised controller 40, as the resistance value of the arrester 34-3 is suddenly reduced by the impression, the over current of it flows to the light emitting elements 36-1 and 36-2. As the result, the light emitting elements 36-1 and 36-2 are lit and the situation that the high voltage of AC 200V is impressed to the terminal of the side of the supervised controller 40 is informed to a worker who tests the connection. Thus the system can be helpful for the repairing of the device 40 and the safety for the worker who tests the connection.

Title: Method and device for physical properties test of coating film of coated steel plate
Inventor: OZAWA HIRONORI
IPC: G01N3/56
Filed: 1980-08-13
Abstract: PURPOSE:To test easily and in a short time the physical properties of a coating film such as an adhesiveness, an abrasion resistance, a flaw resistance by allowing a coated steel plate to contact with a press body in the shape of a convex curved surface, relatively moving them, and varying the pressure of the contact surface. CONSTITUTION:The coating film surface of a coated steel plate X, which is a surface to be tested, and the surface of the opposite side are allowed to contact with a fitting surface 6b of a fitting table 6, thereafter are held with bolts. After subsequently a press body Y which has been worked in the shape of a convex curved surface is held by a holding table 16, the pressing force is adjusted by an adjusting bolt 9 so that the respective curved surfaces of the press body Y and the coated steel plate X are allowed to contact with each other on a prescribed contact surface. One of the fitting table 6 and the holding table 16 is relatively moved against the other at a prescribed moving distance. As a result, since the contact surfaces of the coated steel plate X and the press body Y are allowed to contact with each other as to the curved surfaces, the pressure of the contact surface varies continuously, and also the contact position varies. When this movement is repeated plural times, a flaw or peel-off is caused. The physical properties of a coating film are appreciated by measuring the number of repetition at the point of time when said flaw or peel-off has occurred.
