Title: Inspection device for mask by electron ray
Inventor: UENO YUUKICHI
IPC: G03F1/86
Filed: 1979-07-13
Abstract: PURPOSE:To prevent fouling due to the irradiation to a mask of electron rays by a method wherein the irradiation to a mask transparent portion of electron beams scanned for inspecting dimensions is substantially minimized. CONSTITUTION:The output of a scanning starting point setter 13 is adjusted, and a scanning starting point of electron beams 4 is set at an opaque portion of a pattern, whose dimensions are to be measured. A saw tooth wave generator 14 emits scanning starting pulses 141, resets an FF18, and adds and amplifies 12 scanning signals. The output of the FF is amplified 16, and blanking 15 is conducted so that the beams 4 pass through a hole of a throttle 7 when resetting. Signals from the surface of a mask 3 are detected 6, and compared 17 with threshold value 11, and the FF18 is set when both agree. In this case, the beams 4 are deflected, and do not pass through the hole of the throttle 7. Consequently, a blanking condition is brought when the beams reach a pattern boundary, and the condition is held until the next scanning is started. Thus, irradiation to a transparent portion can be avoided, and the fouling of the transparent portion is substantially minimized.

Title: Optical writing head
Inventor: YAMASHITA JUN
IPC: B41J2/455
Filed: 1987-04-10
Abstract: PURPOSE:To simplify the constitution of a conversion circuit to convert the arrangement of image signals by entering in parallel a line of signals of the first group to the N group into the first set of shift registers and transmitting the signals sequentially to set signals of P bits to each set of shift registers in an optical writing head with MXNXP pieces of light emitting element and a storage location of P bits and also with MXN pieces of shift register to drive the mentioned light emitting elements. CONSTITUTION:The first group - the N group of signal lines are entered in parallel and set into the first set of shift register arranged on the input side of image signals of the M set of shift registers. That is, the signal arrays to be set in the shift registers of the M set are entered by each set from the first set of shift registers, and sequentially transferred. Consequently, for the conversion of a single line of image signals which are entered from an external device, it has only to be performed by each set of shift registers, that is, by NXP bits, thus minimizing the memory capacity and the range of memory addresses. Further, the circuit to convert the arrangement of image signals is extremely simplified.

The output of the differential amplifier 4 is outputted via an integrating circuit having a short time constant comprising a diode 6 and a capacitor 8 as a signal (d) representing the signal level of the burst signal.

Abstract: PURPOSE:To ensure the conveyance of sheets of paper from a sheet contaniner, by using a horizontal slide means to support sheet containers movably back and forth as the containers are in a stacked state, and by using a drive means to appropriately move the containers back and forth to expose the top of the front portion of the desired sheet container. CONSTITUTION:Paper trays 11, 12,..., 1n-1, which are stacked on each other, are supported by slide rails 3, 4, balls 5 and retainers 6 so that the paper trays can be moved back and forth relative to the lower paper trays 12, 13,..., 1n.

Title: Drilling device and inner excavation
Inventor: KITAMURA MORIO
IPC: E02D7/00
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To reduce costs and stabilize and shorten a construction period in an inner excavation technique when a pile is driven. SOLUTION: In a drilling device 10 used in an inner excavation technique, an auger 13 is connected to the shaft 14a of a rotation driver 14 via a connection 15. The connection 15 is movable into the condition that the axis 11 of the auger 13 is decentered. A pile is embedded in the condition that the auger 13 is decentered. In this case, as the auger 13 is moved to be circulated inside the pile 1, the diameter of the screw 12 of the auger 13 is made considerably smaller than the inner diameter of the pile 1. The auger 13 can be used with a small diameter of screw 12. In this way, as the output of the rotation driver 14 is less required, installation costs for the auger 13 and the rotation driver 14 can be reduced. The amount of soil to be discharged is reduced and labor for soil to be discharged is saved.  The rotation stop of the auger 13 due to stone biting is prevented and a construction period is stabilized and shortened.

Title: Marked character reader
Inventor: FUKUTAKA YOSHIMI
IPC: G06K9/20
Filed: 1987-04-10
Abstract: PURPOSE:To prevent read accuracy from deteriorating by scanning a marked surface with a light cutting image, generating two-dimensional distance distribution data to the marked surface from the result of the scanning, and recognizing the distance difference between a marked character part and the marked surface from the two-dimensional distance distribution data and reading characteristics. CONSTITUTION:Slit light SI is projected on the marked surface 12 at right angles to the array of marked characters and linear distance data on a light cut part is generated from the light cutting image SV of the light cut part cut with the slit light SI. Then the two-dimensional distance distribution data on the marked surface 12 is generated from the scanning position of scanning of the light cutting image SV in the array direction of the characters and linear distance distribution data. Then the generated two-dimensional distance distribution data is converted into a light-shade image signal, from which the distance difference between the marked character part 14 and marked surface 12 is recognized to read the characters. Consequently, the characters marked in the marked surface 12 are accurately read even if there are various factors which deteriorate the read accuracy on the marked surface 12 on an object to be read.

Title: Printing pin for dot printer
Inventor: UCHIYAMA TETSUO
IPC: C04B35/48
Filed: 1987-04-10
Abstract: PURPOSE:To obtain ceramic printing pins for dot printer of long life for its improved abrasion resistance and tenacity and light-weight which enable high speed printing by specifying the material used of a composite sinter of alumina- zirconia carbonized silicon. CONSTITUTION:The grain size of part stabilized zirconia powder ranges from 0.1 to 1.0mum. If the dosage is not less than 5%, its efficacy to provide tenacity is not significant. On the other hand, if the dosage is 50% or more, the hardness decreases. Therefore, the typical range is 5-50%. For carbonized silicon whisker, if the aspect ratio is not more than 3, the efficacy of providing tenacity is adequate, and if more than 200, the mentioned effect reduces, so that the range should be 3-200. If the diameter exceeds 1mum, the strength deteriorates, so that the diameter should be 1mum or less. In order to provide the sufficient efficacy of carbonized whisker, the dosage should be at least 3% or more. On the contrary, if the dosage exceeds 40%, the strength deteriorates so that the dosage should be 3-40%.

The surface of the Zn or Zn alloy is then chromated to improve the blackening and corrosion resistances.
