IPC: G10C1/02
Filed: 1994-02-22
Abstract: PURPOSE:To generate no noise, eliminate the need to adjust the gap between a damper wire and a stopping means, and facilitate assembling operation by making the buffer member of the stopping means, arranged between a hammer shank and a damper mechanism, eccentric with a rotary shaft toward a hammer assembly. CONSTITUTION:The stopping means 52 which stops a hammer 28 from rotating unless strings are struck is composed of the rotary shaft 80 which has both end parts pivoted rotatably and the buffer member 81 which is fitted onto the shaft 80. This shaft 80 is divided in the axial direction and composed of plural divided shafts 80A and a connecting member 80B, which has its end part fixed eccentrically with the shaft 80A toward the hammer assembly 24. In this case, the interval gap between the member 80B and a damper wire 74 when the damper mechanism 15 rotates at a maximum angle is set larger. and consequently the wire 47 is prevented from abutting on the member 80B or member 81.

Title: Scale plate of instrument with lighting
Inventor: FUKUSHIMA MASAYUKI
IPC: G01D7/00
Filed: 1980-04-11
Abstract: PURPOSE:To selectively display plural scale displays by forming prescribed scale plates on the front and back of a transparent base material, and providing a light source in the back part thereof. CONSTITUTION:An aluminum vapor-deposited film 14 is formed on the back surface of a transparent base material 12, and the 1st scale 16 is printed on the front surface of the material 12 by, for example, yellow-color ink. The 2nd scale 18 is printed on the film 14 to, for example, a red color, by transmittable ink and the remaining ground part is printed to, for example, a black color, by nontransmittable ink 20. If such display plate 10 is viewed from above, external light L1 is totally reflected by the film 14 and therefore only the 1st scale 16 is observed. If a lamp 23 provided on the back side of the scale plate 10 is lighted, only the 2nd scale 18 is observed. In case when the scale 16 is of a dark color such as black color, the scales on the front and back are displayed simultaneously. In this way, the plural scales are selectively displayed.

Title: Shielded type discharge electrode
Inventor: KIKUCHI MASASHI
IPC: H01J37/32
Filed: 1984-03-14
Abstract: PURPOSE:To prevent the decrease in self-bias voltage and electric power loss and to enable a high-speed treatment of a substrate by interposing an electrically floated shield between a discharge electrode and an earth shield. CONSTITUTION:A shield 6 is interposed in an electrically floated state between a discharge electrode 2 and an earth shield 3 provided in a vacuum chamber 1. Electric discharge arises when electricity is conducted from a high-frequency power source 4 to the electrode 3 and a treatment such as etching is executed to a substrate 5. The total capacitance that the electrode 2 possesses decreases as a result of the shield 6 intervened between said electrode and the shield and since the self-bias voltage to accelerate ions can be thereby increased, the high-speed treatment of the substrate 5 is made possible. Electric power loss is prevented and the release of gas into the chamber 1 is decreased, by which the heat resistance is improved.

Title: Method and device for binarizing image
Inventor: IKUTA KUNIO
IPC: H04N1/403
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To eliminate moire in the case of binarizing a dot image and to speed up processing time. SOLUTION: As to an error caused by binarizing a noted picture element, some picture elements before binarization and in existence in the vicinity of the noted picture element are selected as error sum object picture elements. When the result of binarizing the noted picture element is zero, a maximum value smaller than an upper limit of a picture element value range is selected from an error sum object picture element as a sum object. Then the error is added to the picture element. When the result of binarizing the noted picture element is 1, a minimum value larger than a lower limit of the picture element value range is selected from the error sum object picture element as a sum object. Then the error is added to the picture element.  The shape as dots is maintained by adding the error caused in the noted picture element to unprocessed picture elements before binarization in existence in the vicinity of the noted picture element in this way and no moire is produced. When the addition of the error generated from the noted picture element is finished, since the binarization processing with respect to the noted picture element is finished, high speed processing is attained.
