Title: Apparatus for inspecting pinhole of cylindrical object
Inventor: AJINO SATOSHI
IPC: G01N27/20
Filed: 1984-10-09
Abstract: PURPOSE:To attain to enhance the detection accuracy of a flaw part, by arranging an insulating press plate in opposed relation to the terminal surface of the electrode inserted in the hollow part of a cylindrical object to be inspected. CONSTITUTION:After the chucking of electrodes 1, 12 and an object 5 to be inspected was performed, high voltage with a predetermined level is applied between the electrodes 1, 12. When a pinhole 15 is present in the object 5 to be inspected, spark discharge is generated and a discharge current by discharge is detected by an ammeter 2 and the flaw part of the object 5 to be inspected can be discriminated. Because clearances d1, d2 are respectively provided between the terminal surface of the positive electrode 12 and press plates 7, 9 and between the terminal surface of the negative electrode 1 and the press plates 7, 9, the distance of the creeping discharge route between the electrodes 1, 12 becomes longer than that of the discharge route through the pinhole 15 even if both ends of the object 5 to be inspected are not perfectly and closely contacted with the press plates 7, 9 without forming the gaps therebetween and, therefore, the generation of creeping discharge can be certainly prevented by properly setting applied voltage. As a result, the deterioration in detection accuracy due to creeping discharge during inspection is prevented and highly accurate inspection reaching even the end parts of the object 5 to be inspected is enabled.

Title: Original reader
Inventor: ISHIKAWA YUTAKA
IPC: G06T1/00
Filed: 1984-10-08
Abstract: PURPOSE:To minimize the variable magnification error in the main scanning direction to read originals accurately by setting the joint surface in the one-dimensional direction between a guide member and a slide member, which is attached to a moving member, to a position corresponding to a reference line for the change of the projection magnifi cation of an optical system. CONSTITUTION:A reading element array 6 is attached to a moving base 8, and an end part A of the array 6 is the main scanning start position, and the movement line in the Y direction of the end part A is the reference line in the main scanning direction. A contact B between a guide rail 13a and a slide member 15 is placed just under the end part A. Consequently, the guide line of movement of the array 6 and the reference line in the main scanning (X) direction coincide with each other optically. The contact B is placed just under a reference C in the subscanning (Y) direction of the array 6. If wires 25a and 25b are different in elongation, the moving base 8 is inclined with the contact B as the center. Points D and E indicate both ends of the array 6, and deviation lD of the read width in the point D side is smaller than deviation lE of that in the point E side because of BD<BE. Since a positioning guide 4 on an original platen glass 1 is provided in the point D side, the deviation of variable power reference is reduced when the magnification is varied with the guide 4 as the reference.

Title: Deflection yoke
Inventor: IWASAKI EIJI
IPC: H01J29/76
Filed: 1988-08-25
Abstract: PURPOSE:To enable the easy manufacture of a cathode-ray tube free from any deflection of an image near the center of a fluorescent screen and having a thin type design by applying a coil of a superconducting material having a Meisner effect to cover the portion of a deflection coil made of a superconducting material where a leak magnetic flux passes. CONSTITUTION:Annular coils 401 to 404 constituted with a superconducting material are so formed as to cover the portion of a coil 40 of a superconducting material where a leak magnetic flux passes. The same construction applies to the case of a horizontal deflection coil 50. A leak magnetic flux generated around the horizontal deflection coils 40 and 50 is unable to pass outside due to the existence of annular coils 401 to 404, and 501 to 504, but passes only the opposite magnetic pole faces of the horizontal deflection coils 40 and 50. Consequently, it is possible to obtain a uniform magnetic field on the opposite magnetic pole faces of the horizontal deflection coils 40 and 50, and an image can be displayed without any deflection on every part of a fluorescent screen of a cathode-ray tube without any change of a deflection amount due to a magnetic flux.

Title: Gain control circuit and environment noise collection device
Inventor: MEGATA TSUYOSHI
IPC: H03G3/32
Filed: 1990-08-08
Abstract: PURPOSE:To adjust the sound volume automatically in response to the level of environment noise and to allow the user to hear a small level signal even when the environment noise is large by extracting an envelope noise level with an envelope extraction device so as to decide the amplification factor of a gain control amplifier. CONSTITUTION:When a silence period in a reproduction signal is detected by a silence period detector 10, a switch 130 is thrown to the position (a) for the period. In this case, an earphone 70 applies electroacoustic transducing to the environment noise and amplifies the electric signal by a preamplifier 140 and an envelope extraction circuit 20 generates a voltage in response to the level of the signal at that time, the gain of a gain control amplifier 150 is set higher when the voltage is higher and the gain is set low when the voltage is small. Thus, the amplification factor is high when the environment noise is high and the amplification factor is low when the environment noise is low. Thus, the sound volume is automatically adjusted in response to the level of the environment noise and the user hears a small level signal even under a large environment noise level.

Filed: 1992-08-07
Abstract: PURPOSE:To prevent accelerating of a vehicle in an opposite direction to a direction corresponding to the position of a forward reverse lever at a time when the running direction of the vehicle is reversed through switching operation of the forward reverse lever. CONSTITUTION:When it is detected by a shift sensor 54 during running of a vehicle that a forward reverse lever 53 is switched, it is discriminated by a controller 61 whether a current change gear ratio exceeds a change gear ratio limit. In which case, when it is decided that the current change gear ratio exceeds the change gear ratio limit, a target throttle opening to a current accelerator opening is calculated from a map where the maximum value of the target throttle opening is set to a high value. A step motor 15 for a valve is driven and controlled such that the opening of the throttle valve is adjusted to the throttle opening. Meanwhile, when the current change gear ratio does not exceeds the change gear ratio limit, the target throttle opening is calculated from a map where the maximum value of the target throttle opening is set to a low value, and a step motor 51 for a valve is driven and controlled.

Title: Recording apparatus
Inventor: SHIBUKI TAKASHI
IPC: B41J2/36
Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To prevent a density irregularity at an end part of a recording-paper, by carrying out density correction to a part corresponding to a difference of a large-breadth recording paper and a small-breadth recording paper when the large-breadth recording paper is recorded in the case where images are recorded to recording papers of different breadths with the use of an ink film having a plurality of ink layers formed sequentially. SOLUTION: In the case of printing with the same density in a direction of a thermal head, if the same output value is instructed to the thermal head for an area X and an area Y, a printing result in the area X shows a smaller density than in the area Y. As such, an output value to the thermal head is determined on the basis of a correction table wherein correction output values are related to instructed output values in the area X. In other words, in recording images, breadths of recording papers 18a, 18b are detected, image data are corrected with the use of the correction table, and one line is printed on the basis of corrected data. Whether a regulated count of lines are completely printed or not is judged. The operation is repeated until the regulated count of lines are totally completely printed.

Filed: 1989-08-18
Abstract: PURPOSE:To release the pressure of a pressure roller and that of a peeling claw without touching a fixing unit only by means of opening a cover by interlocking the cover of a device with the pressure release mechanism of the fixing unit. CONSTITUTION:When the cover 1b is opened in the direction of an arrow B, a pressure release lever 7 is rotated in the direction of an arrow C by a tarsion coil spring 9, and the rotation is stopped by a stopper 13. At this time, a roller 10 moves a pressure lever 3 in the direction of an arrow D, whereby the pressure roller 5 separates from a fixing roller 4. When the cover 1b is in a position shown by dotted lines, a shaft 11 moves along the groove part of a frame 14 up to the radium of a base circle of the lever 7. At this time, the part 8a of the peeling claw 8 slides on the stopper 15, and the claw 8 rotates in the direction of an arrow E, which causes the top of the claw 8 to separate from the roller 4. Thus, the possibility that a user may touch the surface of the fixing unit which is at a high temperature in operation can be eliminated.

Title: Sewing machine shuttle
Inventor: TOMITA MASAYOSHI
IPC: D05B57/14
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To obtain uniform seams without a hindrance even in high-speed sewing through the use of a strong bobbin thread by permitting a type to be the vertical one to draw out the bobbin thread in a bobbin axial direction and giving frictive and bending resistances to the lower thread which passes through nearly flange part of a bobbin. SOLUTION: A bobbin case 1 after thread setting is set in an inner shuttle by pushing-in. When a prescribed thread setting to another part is ended so as to execute a sewing operation, the bobbin thread Y is drawn-out in accordance with the advance of sewing. But the bobbin 7 is held in the bobbin case 1 in a non-rotation state and drawing-out of the bobbin thread Y is the vertical type, so that rotation is not executed. Besides, a planar body 14 integrated with a leaf spring 13 is set in the bottom part of the inner shuttle 2 in a shuttle and the planar body 14 is lightly pressurized on the flange part of the bobbin 7 so that a gap does not exist.  Therefore, light frictive resistance is imparted to the bobbin thread Y which is drawn between the flange part of the bobbin 7 and the planar body 14 and oversupply is prevented even at the time of a high-speed operation since the bobbin thread is strong.
