Title: Method and device for detecting welding position of electric resistance welded tube
Inventor: FURUYA YOSHIHIRO
IPC: G01B7/14
Filed: 1993-08-24
Abstract: PURPOSE:To stably detect the weld zone position of the electric resistance welded tube with a high accuracy even after the lapse of a time to some extent after tube manufacturing and further, even if heat treatment is executed. CONSTITUTION:While the electric resistance welded tube is rotated by a turning roller 6, the inside position of the resistance welded tube is measured by a laser displacement gage 4 with high accuracy and further, the outside position in opposition to the same position is measured by an eddy current displacement gage 5 which cannot catch fine variation but has sufficient accuracy to catch eccentricity and vibration of the tube. The net unevenness of the inside not including the eccentricity and vibration of the tube is extracted by taking the difference of both measured values and based on this difference, the welding position is detected.

Title: Inversion phenomenon preventive circuit
Inventor: FUJII KUNIAKI
IPC: G11B20/06
Filed: 1994-09-02
Abstract: PURPOSE: To prevent the inversion phenomenon of an FM signal by digital processing with simple circuitry by inputting the reproduced FM signal to a BPF and adding the output signal thereof to an original digital signal through a nonlinear circuit. CONSTITUTION: The BPF allows passage of only the prescribed band component (9.5MHz±300kBz) of the reproduced FM signal subjected to digitalization processing and outputs the signal having zero-crossing waveforms even in a period of a lowered decreased signal amplitude when the FM signal is inputted to the BPF as the signal having the waveforms possessing the non-zero crossing distortions to be the cause for an inversion phenomenon. The FM signal is suppressed in its amplitude by the nonlinear circuit 2 and is made to have the waveforms in which the parts of the large amplitude are drastically suppressed. The signal is mixed with the original signal by an adder 3 and is intensified in the high-frequency range with respect to the original signal. The signal is outputted as the signal of the zero-crossing waveforms to an FM demodulation circuit.

Title: Marked character reader
Inventor: HIRAOKA NORIYUKI
IPC: G06V10/10
Filed: 1982-11-30
Abstract: PURPOSE:To obtain a sufficiently high contrast and to ensure the reading with high reliability by making use of a fact that the light made incident vertically to a flat part is reflected obliquely on a sloping surface near the edge part of a marked character. CONSTITUTION:The light irradiated from a light source 1 transmits through a half mirror 5 and irradiates the surface of an object 2 to be read through an aperture 7 provided on the bottom surface of a view camera 6. The light reflected on the surface of the object 2 passes through the aperture 7 and is made incident to a line sensor 8 after reflected in the direction of a lens 3 by the mirror 5. When the aperture 7 is set at a flat area on the surface of the object 2, the optical paths of both projected light and reflected light are vertical to the surface of the object 2 to give a high level of a detection signal. If the aperature 7 is set on a groove, the projected light is made incident obliquely to the surface of the object 2 and its reflected light is not virtually sent back to the aperture 7. Thus a detection signal of a low level is applied.

Filed: 1990-08-10
Abstract: PURPOSE:To accurately detect a residual quantity without causing malfunction by making a detection cycle different between at the time of performing replenishing work and at the time of performing developing action and setting the optimum detection cycles for the respective cases. CONSTITUTION:Toner residual quantity is detected at the time of performing the toner replenishing work to a container simultaneously with performing the developing action, and the detection cycle at the time of performing the replenishing work is set smaller than that at the time of performing the developing action.

Title: Internal combustion engine controller
Inventor: KAMURA HITOSHI
IPC: F02D41/14
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To reduce torque-down at the time of fuel returning from a fuel cut mode. SOLUTION: When the detected result of a water temperature sensor 16 exceeds prescribed value, out of the first half period jetting lean mode and the second half period jetting lean mode, the second half period jetting lean mode, where combustion becomes stable at a low temperature, is made selectable. When detected result of the water temperature sensor 16 exceeds the second prescribed value higher than the prescribed value, both the first half period jetting lean mode and the second half period jetting lean mode are made selectable. Even during warming-up, the second half period jetting lean mode, where combustion becomes stable at a low temperature, is permitted, so that fuel jetting with lean air-fuel ratio can be conducted during a compression stroke.  It is thus possible to improve fuel consumption in a stable combustion condition and improve drivability without causing combustion deterioration.

Abstract: PURPOSE:To perform the laser beam machining under noncontact state by providing a couple of movable workpiece supporting jigs to support a machining part of a workpiece from the lower part and maintaining the positional relation with respect to a machining head to interlock and fix these. CONSTITUTION:A couple of rollers 8 to support the workpiece 3 from the lower part with an optical axis C in-between supporting pins 2 of a table 1 are provided and the positional relation between the rollers 8 and the machining head 4 is maintained and these rollers 8 and head 4 are arranged so as to be interlocked and fixed. When the head 4 is moved in the X direction, the rollers 8 are also moved integrally and when the head 4 is moved in the Y direction, the positions of the rollers 8 are fixed. Since the machining part of the workpiece 3 is supported on both sides of the lower side of the optical axis C, the distance between the head 4 and the workpiece 3 is maintained constant and a contact type sensor becomes unnecessary. Accordingly, the laser beam machining under noncontact state is made possible by this method.
