Title: Error detection circuit
Inventor: SATO HIROSHI
IPC: H03M1/10
Filed: 1990-05-31
Abstract: PURPOSE:To reduce a burden on a microcomputer with a simple circuitry by building up an error detection circuit with a D/A converter and an analog converter. CONSTITUTION:A microcomputer 10 calculates upper limit values and lower limit values of signals corresponding to input signals 1-4 to be outputted to a D/A computer 5 sequentially. The computer 10 latches an output of a comparator 6 at a timing of outputting the upper value of the input signal 1 to judge whether the output is normal or abnormal. Then, the computer 10 latches the output of the comparator 6 at a timing of outputting the lower limit value of the signal 1 to judge whether the output is normal or abnormal. Thereafter, the same operation is performed at a timing of outputting the upper and lower limit values of the signal 2 and the signals 3 and 4. Thus, such a use of one D/A converter 5 and four comparators 6-9 enables judgment of whether the four input signals 1-4 exceed upper values allowable threshold respectively or not and whether they are below the respective lower limit values.

Filed: 1986-06-18
Abstract: PURPOSE:To prevent picture quality from deterioration by arranging a member for interrupting the deformation of a sheet at a suction port of residual toner. CONSTITUTION:Rollers 3a, 3b are arranged on an aperture part 2a of the suction part 2 opposed to the sheet 1 and its surface is worked so as not to stick toner. In order to prevent removed toner from being discharged from space between the aperture 2a and the sheet 1, brush-like sea 1 members 4a, 4b are arranged. Even if air suction for the removal of toner is executed in said constitution, the deformation of the sheet 1 is suppressed and the picture quality can be prevented from deterioration due to the deformation by fixing the interval between the rollers 3a, 3b at a proper value.

Title: Program control device of bending machine
Inventor: HONGOU TOSHIO
IPC: B21D5/02
Filed: 1978-11-15
Abstract: PURPOSE: To let a dog contact a screw and determine bending width by step-revolving a cam group together with the cassette screwed with the setting screw as well as to improve the efficiency of bending by the operation signals of the cams.  
     CONSTITUTION: When a striking piece 22 is moved near the groove 19 of an upper die 13, a dog 23 contacts a set screw 27 and determines a striking length. Next, the end edge of the work is contacted to the striking piece 22 and the upper die 13 is lowered by treading a pedal, whereby the end part is bent. Thence, when a cassette 25 is revolved by a motor 46, a plate cam and one of limit switches LS 1-3  go ON and the float 17 of the lower die floats. In this gap, the bent part of the previous process is pressure flattened. When it is step-revolved after this, one of the limit switches goes ON to let the upper die 14 ascend, then the striking piece 22 retreats and at the same time it advances a moving plate 15. Namely, the set screw 27 of this stage strikes against the dog 23, by which the bending width is determined and the work is bent sequare by the upper die 13 and working groove 19.

Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To display various information concerned with a brake point such as the sort of a set brake point, whether the brake point is valid or not and the number of times of passing brake points when a program is executed. SOLUTION: In the program preparation device 1, a debugging execution part 20 displays the sorts of brake points such as a brake point whose condition has been set, a brake point whose period has been set and a brake point set as an invalid brake point so as to easily recognize them on the screen of a display device 30. The display colors of brake point markers and the sorts of display fonts of information concerned with these brake points are made different so as to discriminate that a brake point is the one whose condition has been set, the one whose period has been set or the one set as an invalid brake point. The current number of times passing brake points is displayed. Consequently, the sorts of brake points or a current state can be easily grasped without checking the sort of each brake point during the period of debugging by the debugging execution part 20.

Abstract: PROBLEM TO BE SOLVED: To always obtain a desired size with respect to the desire of a user, etc., by making selective setting whether an original image is transferred in an unmagnified state regardless of the width of a blank or copied with reduction ratio corresponding to the width of the blank possible. SOLUTION: A photoreceptor drum 1 electrified to a uniform potential is irradiated with laser beam, and developing is performed on a part whose potential becomes small with toner having the same polarity as the electrified polarity of the drum 1. Consequently, since developing is not performed on a part which is not irradiated with the laser beam, an area equivalent to the blank is controlled not to be irradiated with the laser beam. As to this operation, first, a blank button among items displayed by the pressing of an application mode button is pressed, so that a screen is shifted to a blank width setting screen. After all of the initial set values of four sides are set to 1.5 mm, for example, and figure are inputted with up and down buttons with respect to the initial set values; an OK button is pressed.  By this operation, the desired blank width of the four peripheries of a transfer material can be set, so that the user can change the width of the blank as he or she wishes in terms of the desire of the user, the kinds of the original image, etc.

IPC: A47K17/00
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a water-closet bowl which facilitates the cleaning of a floor. SOLUTION: A main body 31 of the water-closet bowl 3 having the main body 31 of which the flank 31A rises from a floor surface 2A is provided with an edge member 34 for receiving dew condensed on the flank 31A so as to prevent the dew from dropping to the floor surface along the peripheral edge of the bottom edge of the main body 31. Even if the dew condensation occurs on the surface of the main body 31 at the time of the rainy season or in the winter or a cold season, the dew creeping on the surface of the main body 31 is received by the edge member 34, by which the penetration of the dew into the floor 2 is prevented and the spreading of the dew over the entire part of the peripheral edge of the main body 31 along the spacing between the bottom end and the floor 2 is prevented as well.  As a result, the floor 2 is kept substantially free of the contamination with the dew and the easy cleaning of the floor 2 is made possible.

IPC: G11B21/08
Filed: 1995-06-08
Abstract: PURPOSE: To attain the reproduction of images and voices at various speeds by varying the reproducing speed not by varying the rotational speed of a disk and the signal reading speed of a head but by varying the timing of track jump and the reading speed of the storage means. CONSTITUTION: The rotational speed of a disk 1 is usually kept at (a) times the usual speed. The recording signal of the disk 1 is read out by a head 2 at a (a>1) times the usual speed and, after demodulation, is once written into a memory circuit 8. Based on the variable speed magnification x (0<x<1) set externally, a timing generating circuit 16 generates track jump and the writing address of the memory circuit 8. The dividing ratio of the variable clock which determines the reading speed of the memory circuit 8 is set. The amount ratio between the written data and the read data of the memory circuit 8 in a specified period of time is kept at about 1:1 by controlling the generation of the track jump and the written address of the memory circuit 8.
