IPC: G01R31/12
Filed: 1985-05-27
Abstract: PURPOSE:To effectively prevent a noise from generating by forming a high voltage generator of a DC high voltage generator and an arbitrary waveform high voltage generator which interlocks with the previous generator, and control ling the combined output voltage from the both. CONSTITUTION:A high voltage generator 1 is composed of a DC high voltage generator 1a and an arbitrary waveform high voltage generator 1b. The genera tor 1a has a DC transforming circuit 2a, an operating DC power source 3a, an output voltage setter 4a and a switch 5a, and the generator 1b has, in addi tion to the above, a low frequency arbitrary waveform generator 6, an amplitude setter 7 and a interlocker 8, and both are interlocked by the interlocker 8. A device 14 to be tested is connected with the output terminal 9, and an output is controlled by a feedback circuit of a route 13. Thus, a differential output is obtained from the output terminals 10, 11 of the generators 1a, 1b, and the DC side 1a is set higher than the arbitrary side 1b. Accordingly, an insulating strength can be sufficiently held.

Title: Semiconductor laser
Inventor: HAMADA TSUTOMU
IPC: G11B7/125
Filed: 1986-05-19
Abstract: PURPOSE:To lengthen the focal distance of a converging lens to facilitate the adjustment of the converging lens and to lessen the influence of thermal expansion, by providing a lens to minimize the spreading angle of a laser light between a laser chip part and a converging lens. CONSTITUTION:Laser light to occur from a laser chip part 3 has a spread and the laser light passes through a lens 5 placed so as to be approximately concentric to the light and orthogonal to a light axis center. Thus, the laser light probably has the spreading angle to light-emit at an A point and enters a converging lens 6. The lens 6 is adjusted in the light axis direction and comes to be parallel light. Consequently, the focus distance of the lens 6 comes to be (f) and in proportion to this, the adjusting allowable scope of the lens 6 is spread.

Title: Color recording apparatus
Inventor: OKAMOTO HIDEAKI
IPC: B41J2/07
Filed: 1986-05-19
Abstract: PURPOSE:To perform recording even on a different recording medium simply and accurately, by providing a control means wherein a positive image or a mirror image is recorded on a recording medium and color overlapping order is reversed at the time of the recording of the positive image and at the time of the recording of the mirror image to perform recording. CONSTITUTION:A bar code 43 is printed on the end part of a B.P.F. sheet and, when the sheet is mounted between feed rollers 2, 3, the discrimination sensor 35 comprising an optical sensor provided at the position corresponding to the bar code 43 reads said bar code 43 to confirm the B.P.F. sheet. Because no bar code is applied to usual recording paper, the discrimination of the B.P.F. sheet is certainly performed. CPU21 delays the timing of an ink emitting order on the basis of the values of distances D1-D3 from a nozzle 9C coming to a standard one through a delay circuit 64 and performs control so that the matching of the scanning position of a carriage and the recording position of each recording nozzle is performed, that is, overlapping printing is performed in an accurately matched state.

Title: Automatic focusing method
Inventor: ENOKIDO EITARO
IPC: G01B15/00
Filed: 1988-05-11
Abstract: PURPOSE:To make the initial probing of the signal intensity curve to the focus coil current easier by carrying out a division control and a shift control of the focus coil current from the signal for one line scanning, when the signal intensity larger than a noise level is not obtained. CONSTITUTION:The signal intensity curve is probed by carrying out a division control and a shift control of the focus coil current from the signal for one line scanning, and the maximum signal intensity is probed by controlling the gain of the signal level. Therefore, when the signal intensity larger than a noise level is not obtained, the focus coil current is converted in 1/2 shift of the division pitch, and furthermore, in the double division step of 1/4 shift. As a result, the signal intensity curve can be probed rapidly in the process of fewer division number.

Title: Form peeling device of electrostatic photographic printer
Inventor: OOBA HARUTAROU
IPC: G03G15/00
Filed: 1984-06-04
Abstract: PURPOSE:To prevent dirt of an unfixed part on a form and transfer of this part to another part and simplify the structure by attaching a wheel body, which is provided with plural needle-shaped projections on the outside peripheral surface, to the front end of a guide part and guiding the form while retaining the leading edge of the form with the guide part to peel the form gradually even in the center part of a photosensitive body. CONSTITUTION:When a photosensitive drum 9 is rotated, one end of a form 19 is peeled by a peeling part 26. The leading edge of the form 19 is retained still by a guide part 27, and the form is separated from the photosensitive drum 9 gradually according as going from one side to the center part, and the form is easily separated from the photosensitive drum 9 even in the other side where a peeling body 25 does not exist. Consequently, the form 19 is led smoothly toward a conveyor 17 to prevent jam, and the form 19 which passes a transfer charger 14 has the center part brought into contact with a wheel body 29. Though this center part is the unfixed part where characters and images (toner image) are left transferred, this part is not transferred to another part because needle- shaped projections 28 are formed on the outside peripheral surface of the wheel body 29, and thus, dirt of the form 19 is prevented.

Title: Transmission system for digital facsimile signal including intermediate image gradation
Inventor: NAGAYAMA YUTAKA
IPC: H04N1/41
Filed: 1981-07-20
Abstract: PURPOSE:To obtain an intermediate image gradation with high universality, without deteriorating the compressing efficiency, by changing a slice level according to a predetermined rule of repetition for an analog signal including the intermediate gradation, and binarizing the signal. CONSTITUTION:First, an analog signal including an intermediate image gradation of the 1st scanning line being an odd number order is dithered by taking slice levels as L1 and L2 and transferred to an arrangement converter 11. The converter 11 sequentially classifies the dither with difference slice levels L1 and L2 and transfers it to a coding line memory 121. The 2nd scanning line at an even number order is processed according to the same steps by taking slice levels as L2 and L4, and the result is transferred to an encoding line memory 122. After the end of transfer, the content of the memory 121 is transferred to an encoding circuit 14 for sequential primary dimension encoding. Further, the same operation is done for each scanning for the completion of encoding.

Title: Preparation of opening lid of simple opening can

IPC: B65D17/34
Filed: 1987-05-11
Abstract: PURPOSE:To uniformize the thickness of a thin wall part and to prevent the leakage from a thin wall part carving part, by mounting a tab to a lid part and subsequently carving the annular thin wall part in the lid part while rotating said lid part. CONSTITUTION:A lid part 2 has such a cross-sectional shape wherein a protruding part 23 equipped with a projection as a tab 3 is formed to the center and a ridge 24 concentric to the protruding part 23 is formed to the outer periphery of said protruding part 23. In the case of the lid part 2 thus constituted, an annular bottom part 25 having a definite width is formed between the protruding part 23 and the ridge 24 and, after the peripheral edge of the lid part 2 is clamped to the open end part of a can container 1 by caulking, a cutting tool 4 is penetrated in the central part of the annular bottom part 25 while the can container 1 is rotated to carve an annular thin wall part in the bottom part 25. Since the cutting amount of the lid part in the wall thickness direction thereof is determined by the penetration depth of the cutting tool, said cutting amount becomes constant in the processing region of the lid part in the wall thickness direction so far as the lid part 2 rotates on one plane or cylindrical surface. As a result, the irregularity in the thickness of the thin wall part becomes hard to generate.
