Title: Magnetic recording and reproducing device
Inventor: KUGE SATORU
IPC: G11B15/087
Filed: 1995-05-30
Abstract: PURPOSE: To keep a sufficient lead time for a time code recording/reproducing circuit to process the time code and to secure a continuity of time code in the case of a consecutive recording by transmitting and receiving the time code at a specified period by a system computer. CONSTITUTION: In the case of a consecutive recording, a magnetic tape 18 is reproduced after rewound once. A time code included in a reproducing data and incremented at every 33msec is reproduced by a time code recording/ reproducing circuit 14 and detected by a system computer 22 at a period of 18msec. When detected time codes coincide with each other two times successively, the system computer 22 generates another time code by adding '2' to the above time code and transmits it to the time code transmitting/receiving circuit 14 at an elapse of 18msec after detecting the preceding time code. The time code recording/reproducing circuit 14 outputs so that this time code is recorded from the next frame of the one being currently reproduced.

Filed: 1982-07-28
Abstract: PURPOSE:To detect the deterioration of a powder developer accurately, by providing a developer resistance detecting means consisting of a high frequency power source and counter electrodes for detecting variation in the resistance of the developer. CONSTITUTION:A detection coil is inserted in a toner density detector 10 and a toner density variation signal based upon variation in the inductance of the coil is supplied to a control part 15 and compared with a reference value, when the signal is lower than the reference value, a density decrease signal is outputted to rotate a supplementing roll 14 to hold the toner density constant.

Abstract: PROBLEM TO BE SOLVED: To reduce the center segregation without developing negative segregation zone by increasing the intervals of guide rolls in the thickness direction of a cast slab step by step, developing the bulging and successively, regulating rolling reduction till the completing point of solidification. SOLUTION: Molten steel 8 is poured into a mold 1 to form solidified shell 2a and drawn out as the cast slab 2 through pinch rolls 7. At this time, in a bulging zone, the guide roll group 3b between the liquidus crater end 9a of the cast slab 2 and the end part of the bulging zone increases intervals βin the thickness direction of the cast slab 2 step by step in the casting direction to develop the bulging and the max. thickness of the cast slab 2 is made 10-50% of the short side length γ of the mold 1. Further, the rolling reduction of >=10% of the short side length γ or the mold 1 per one pair of rolling reduction rolls is given in the thickness direction of the fast slab 2 by using at least a pair of rolling reduction rolls 5 in the interval from the end part of the bulging zone to the solidification completing point 9b.  By this method, the center segregation can efficiently be reduced with the small rolling reduction force.

Title: Variable branch ratio type optical coupler
Inventor: HAYAKAWA KOICHI
IPC: G02B6/28
Filed: 1989-05-29
Abstract: PURPOSE:To vary the branch ratio of light by arranging a movable medium which makes a refractive index distribution nearby a drawn and fusion-spliced part different with the position nearby the drawn and fusion-spliced part. CONSTITUTION:The movable medium 6 which makes the refractive index distribution nearby the drawn and fusion-spliced part 4 difference with the position is arranged nearby the drawn and fusion-spliced part 4. Confining operation for a light is weak at the drawn and fusion-spliced part and the light is diverged to a fusion-spliced clad part 2B and its periphery, so the state of optical coupling between optical fibers 1A and 1B at the drawn and fusion-spliced part 4 varies by varying the state of the peripheral medium i.e., the distribution of the refractive index. Consequently, the branch ratio of the fusion splicing type optical coupler is varied through easy operation.

Title: Driving method for plasma address liquid crystal display device
Inventor: IWAMA JUN
IPC: G09G3/36
Filed: 1995-05-02
Abstract: PURPOSE: To provide an inverse driving method so that no defective display appears in spite of chipping-off part in a separate structure of a horizontal scanning line. CONSTITUTION: A plasma address liquid crystal display device is provided with a flat panel 0, a driving circuit 1 and a scanning circuit 2. The flat panel 0 has a mutually laminated structure of plasma cells provided with charging channels constituting the horizontal lines and liquid crystal cells provided with signal electrodes D constituting the vertical lines. The scanning circuit 2 repeats for each field a successive line scanning for a selection of a horizontal line by successively discharging the discharging channels. The driving circuit 1 impresses the signal electrodes D with a polarity inversing AC signal in synchronism with the successive line.  This driving circuit 1 sets a delimiter to divide the horizontal lines at every multiple lines, and inverses the polarity of the AC signal every time when the horizontal line selected according to the successive scanning exceeds the delimiter. In this case, two successive fields control the delimiters to be the same, while controlling the AC signals to be inverted to each other on the other hand. Further, the positions of the delimiters are altered at every two fields and the horizontal lines influenced by the polarity inversion are dispersed through multiple fields.
