Title: Picture signal coding system
Inventor: KAGAMI NAOTO
IPC: H04N1/419
Filed: 1984-05-30
Abstract: PURPOSE:To attain a picture signal coding system which can work at a high speed with small memory capacity by storing the changing points of picture signals of each scan line in the form of the number of run lengths and obtaining the coding data from the corresponding address in a coding table based on the stored run length number. CONSTITUTION:The serial picture signals supplied from a reading circuit 1 are supplied directly to a changing point detecting circuit 2 to detect the white and black changing points. Then the run length number, i.e., the output of a run length counter 10 corresponding to said white and black changing points or the abbreviated run length number given from an abbreviated run length producing circuit 9 is stored to a picture signal buffer memory 4. At the same time, the counter 10 is cleared. Then an MPU5 reads data out of the memory 4 and designates the address of a coding ROM table 6 to read out the coding data.

Title: Electrophotographic device
Inventor: YANAGIDA MASAHITO
IPC: G03G21/10
Filed: 1995-05-02
Abstract: PURPOSE: To clean even such a toner that is hardly wiped off with a cleaning blade by applying a material having a low frictional coefft. by using an electrifying roller or a transfer roller or transfer belt. CONSTITUTION: While a rotary solenoid 17 is not energized, an electrifying roller 2 is apart from a photoreceptor 1 and a zinc stearate block 3 is apart from the electrifying roller 2. When the rotary solenoid 17 is energized, a rotating arm 19 rotates by an angle α in the counterclockwise direction to move a cam rod 20. In this process, the electrifying roller 2 first is brought into contact with the photoreceptor 1 and then the zinc stearate block 3 is brought into contact with the electrifying roller 2. In this stage, zinc stearate is transferred from the block 3 to the electrifying roller 2 and then transferred from the electrifying roller 2 to the photoreceptor 1. Namely, the zinc stearate is applied on the photoreceptor 1. Therefore, when electrification or cleaning is needed, the rotary solenoid 17 is energized.

Title: Anchor of board receiving no pressure and anchoring method thereof
Inventor: NAKAMURA HIROYUKI
IPC: E02D5/80
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To keep a natural condition, by embedding an anchor of the movable layer side of a tension member arranged in the length extending from the fixed layer to the movable layer, within the movable layer so as not to be exposed on the ground surface. SOLUTION: Existing trees 9 on the ground surface 13 are left as they are and a hole 12 extending from a movable layer 10 composed of weathered rocks or the like to a fixed layer 11 composed of base rocks or the like is drilled. Then, an anchor 1 of a board receiving no pressure is inserted in the hole 12 and grout is injected to construct an anchor without a board receiving pressure on the ground surface. The grout material and the anchorage body integrally formed in the layer 10 by the anchor 1 mutually pull the grout material and the anchorage body integrally formed in the layer 11 by the compressive force of pretensioned tensile members and the layers 10, 11 are compressed by the frictional resistance of the peripheral face against the anchor 1 at the boundary of the sliding face 19.  The anchor directly acts to the nearby position of the sliding face 19 of the layer no to prevent the layer from sliding. In this way, the anchor can be set while existing trees can be left as they are, and as the anchorage body is embedded, trees can root easily.

Title: Gamma correction method
Inventor: HYODO MANABU
IPC: H04N9/11
Filed: 1994-05-24
Abstract: PURPOSE:To avoid a defect in which noise of an image pickup system or a granular state of a film is remarkable even in the case of gamma correction by setting a differentiation value of a curve representing an input output characteristic in a gamma correction circuit to be a prescribed value or below. CONSTITUTION:A CCD line sensor 14 reads an image of a color photo film to be lighted, an A/D converter 18 converts the image into a digital signal and the converted signal is given to a signal processing circuit 20. The circuit 20 conducts white balance, black balance, negative/positive inversion, and gamma correction or the like for each of R, G, B signals. A lookup table storing base correction value for each gradation is prepared for gamma correction. A correction value is obtained by multiplying a gamma gain for each of R, G, B with a gamma correction value read based on point sequential R, G, B digital image signals and gamma correction is applied to each color data by subtracting the correction value. Furthermore, a variable range of the gamma gain to be multiplied is limited to avoid loss of monotonous increasing performance by preventing adjacent differences (differentiation value) from being too high as a lookup table content.

Title: Video signal read system
Inventor: TERAOKA TOYOHISA
IPC: H04N7/18
Filed: 1979-08-29
Abstract: PURPOSE:To prevent a rewritten part of the screen, by moving the start point of horizontal sweep according to advance of vertical scanning and by starting horizontal sweep from the address where write is performed currently. CONSTITUTION:The WRT signal generated from WRT control circuit 3 and the READ address signal generated from READ control circuit 4 are applied to comparator 5. Comparator 5 compares the current WRT address with the READ address and corrects the READ address so that the position of the vertical scanning line where write is performed currently may be always the start point of the horizontal scanning line for read, and the result is fed back to READ control circuit 4. Thus, the READ address signal is generated in circuit 4 with the position of the vertical-direction write scanning line as the start point, and as the result, the write scanning line is always at the edge of the screen or outside the screen, so that the rewriting line of old and new pictures is not shown within the screen.

Title: Rotating direction detector
Inventor: SUZUKI SUSUMU
IPC: G01P13/04
Filed: 1983-06-17
Abstract: PURPOSE:To detect the rotating direction easily and accurately by judging the rotating direction according to the results of edge detection of two phases of pulses corresponding to the rotation and the coincidence or noncoincidence of sampled values thereof. CONSTITUTION:Two phases of pulses corresponding to the rotation different in the phase such as 90 deg. outputted from a rotation detecting mechanism (a) are sampled in the level H and L at smaller time interval than the phase difference of both the pulses during the maximum rotation by a sampling means (b) and the current sampled values are compared with the previous ones respectively to detect edges of the two phases of pulses with an edge detection means (d). Based on the results of the detection and the results of the comparison to determine the coincidence of the current sampled values by a coincidence detection means (e), the judging means (f) determines the rotating direction of a rotor. Thus, the correct rotating direction can be judged even when the sampling cycle exceeds the quarter of the cycle of the pulses thereby making the setting of the sampling cycle so large as to enable the detection of the rotating direction easily and accurately.
