Title: Machining method of polyester or polyamide thin film having nonreflexive surface for covering measuring tape
Inventor: RI SHITSU
IPC: B24B7/30
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To clear the scales on the surface of a measuring tape for easy reading by avoiding reflection on the surface. SOLUTION: Either side of a polyester or polyamide thin film is ground with sand rolls of different grain sizes in succession to have a frosted side that had been a glossy one. When glued to the surface of a measuring tape where its scales are printed, the polyester or polyamide thin film with the fronted side makes on the measuring tape a nonreflexive surface of a sort, which by contraries makes the scales easier to read.

Abstract: PROBLEM TO BE SOLVED: To prevent the engagement between a lens barrel driving mechanism and a planet mechanism from being carelessly detached by providing a mechanism by which the rotation of an electric motor in a direction reverse to the rotation direction in the case of transmitting the rotation of the electric motor to a lens barrel is obstructed on a gear constituting a gear train. SOLUTION: When driving force is transmitted to an engaging gear 105 through a planet gear 104b, the driving force is further transmitted to a reduction gear train 106 through the gear 105. The driving force transmitted to the gear train 106 is transmitted to a reduction gear train 109 through two bevel gears 107 and 108. A ratchet mechanism is provided on one gear 109a constituting the gear train 109. Since the ratchet mechanism is provided on the gear 109a in this way, the gear is prevented from being reversely rotated even though force in the reversely rotating direction is applied to a rotating movable barrel in the state that the planet mechanism 104 is engaged with the gear 105 and the motor 54 stops.

Abstract: PURPOSE:To transfer data at a high speed by providing two buffers to input and output data to and from buffers simultaneously. CONSTITUTION:When a buffer select signal 21 is '1', data on a data bus I15 is outputted to a data bus A12A, and input data is written on a buffer A11A when a write signal 13A of the buffer A11A becomes '1'.

Title: Marker detection device
Inventor: OKAMURA KOICHI
IPC: H04N1/38
Filed: 1994-09-29
Abstract: PURPOSE: To prevent a halftone picture in an image area from being errorneously detected as a marker in a marker detection device detecting an area (namely, the marker) on an original, which is marked by a marker pen. CONSTITUTION: When the density of picture data read is between the upper limit threshold part 2-1 and the lower limit threshold part 2-2, a comparator 2-3 judges it to be the marker and outputs '1'. If not, it outputs '0'. When picture data is within the image area, the value of an image area signal is '0'. If not, the value is '1'. When picture data is within the image area, a mask circuit 2-5 inhibits the output of the comparator 2-3. Thus, even if the halftone picture exists in the image area, and the picture is judged to be the marker in the comparator 2-3 the picture is prevented from being transmitted to a marker area judgement part 2-4 as a marker detection signal.
