Title: Multiplex magnetic recording and reproducing device
Inventor: SUWA TETSUYA
IPC: G11B5/02
Filed: 1986-10-17
Abstract: PURPOSE:To attain an optimum recording by reproducing a PCM signal from a magnetic tape, detecting and measuring an error ratio, detecting the timing when the ratio is below a prescribed permissible range and storing the recording level of a recording means at that timing. CONSTITUTION:An action timing control signal is supplied to an A/D converter 38 from an action time control part 30b in a microcomputer part 30. The action timings are sequentially changed. A buffer and an interface 39 average the error ratios of PCM audio reproduction signals at every action timing, and the mean is supplied to the microcomputer part 30. It always monitors the mean of the error ratios in each action time. If the part 30 detects that the mean of the error ratios after time (t) exceeds the prescribed permissible range L, the reading of a register, which was given to a D/A converter in time t1 when the signal was recorded is stored in a memory 31. Thus the gain of a control amplifier 22 can be attained. The amplifier 22 can most suitably record the signal just before the error ratio exceeds the permissible range L.

Title: Image forming device
Inventor: SAITO TATSUHIKO
IPC: G01N27/00
Filed: 1989-09-22
Abstract: PURPOSE:To accurately measure the amount of offset, which is required for measuring the surface potential of a photosensitive body by making a distance from a potential measuring means to a ground plate, which is positioned between the photosensitive body and the potential measuring means when the surface potential of the photosensitive body is not measured, equivalent to a distance from the surface of the photosensitive body to the ground plate, thereby setting the same positional conditions as when the surface potential of the photosensitive body is measured. CONSTITUTION:When the potential measuring means 50 measures the surface potential of the photosensitive body 12, the end part of the ground plate 54 is made to move to a position shown by a symbol A, and consequently the detection surface 53 of the potential measuring means 50 is positioned so that it faces the surface of the photosensitive body 12. When the potential measuring means 50 does not measure the surface potential of the photosensitive body 12, the end part of the plate 54 is made to move to a position shown by a symbol C, and consequently it is set in the position where it shields the detection surface 53 of the potential measuring means 50 against the surface of the photosensitive body 12. Even when the potential measuring means 50 does not measure the surface potential of the photosensitive body 12, the means 50 is put in the same positional condition as when the detection surface faces the surface of the photosensitive body 12; therefore, potential corresponding to the amount of offset of sticking substance, such as toner sticking on the detection surface, can be measured in this condition.

Title: Apparatus for producing compound semiconductor single crystal
Inventor: KAWASE TOMOHIRO
IPC: C30B15/22
Filed: 1990-09-19
Abstract: PURPOSE:To facilitate the control of the diameter of a pull-up crystal by floating a disk having an aperture at the center and having the outside diameter approximate to the inside diameter of a crucible on the surface of a liquid sealant or immersing and holding this disk in the sealant. CONSTITUTION:The disk 9 having the aperture at the center is formed of a material having the sp. gr. smaller than the sp. gr. of the liquid sealant or is formed to a boat shape in the case of the material having a large sp. gr., by which the disk is floated on the surface of the liquid sealant. The disk is otherwise immersed and held in the liquid sealant by using an auxiliary shaft, etc. The greater part of the heat dissipation from the surface of the liquid sealant is suppressed by this disk 9 and a large quantity of the heat is escaped from the aperture at the center of the disk 9. The temp. gradient in a radial direction is maintained relatively large even at the time of lowering the temp. gradient in the axial direction of the growth on rising of the ambient temp. as the temp. at the center of the raw material melt 7 is liable to fall. The controllability of the diameter in the growth crystal is improved by adjusting the aperture area at the center of the disk 9.

Title: Transfer base material film
Inventor: UCHIUMI SHIGEO
IPC: B41M5/41
Filed: 1990-09-18
Abstract: PURPOSE:To provide the title base material film having excellent characteristics and enhanced in industrial value by forming said film from a composite polyester film wherein the layer constituting at least the single surface thereof is composed of a copolyester layer with a copolymerization ratio of 5-30mol.%. CONSTITUTION:A composite polyester film consists of at least one copolyester layer A and other layer B. A copolymerization ratio means the sum of mol.% of the copolymerized component in the total dicarboxylic acid component constituting copolyester and mol.% of the copolymerized component in the total dial component constituting said copolyester. The copolymerization ratio of the copolyester layer is within the range of 5-30mol.%, pref., 10-25mol.%, more pref., 15-22mol.% and, when the copolymerization ratio exceeds 30mol.%, no proper effect is obtained because an obtained biaxially stretched film is inferior to tenacity and a shrinkage factor becomes too large. When the copolymerization ratio is below 5mol.%, the printability of a transfer film can not be improved.

Filed: 1983-12-27
Abstract: PURPOSE:To minimize the wastefulness of an ink film without lowering a printing speed, by providing a discharging drive source, which performs only the discharge and accumulation of cut paper after printing outside the apparatus, other than a man drive source. CONSTITUTION:The titled apparatus is constituted so that only a discharge roller 4 for exclusively discharging cut paper 6' after printing to the outside of the apparatus to accumulate the same thereon is separated from a paper feed drive system so as to be made independent and said drive roller 4 is driven by the discharge motor 10 such as a DC motor. One-way clutches for preventing the reverse rotation of a feed roller 3 and a platen roller 2 are respectively provided to timing belt pulleys (a), (b) and used in the drive transmission with the shafts of said pulleys. Because printing and discharge operations are separately performed and an ink film 8 is fed only for a printing period during a T3-period, the wasteful feed of the ink film 8 can be eliminated. Further, discharge operation can be performed in parallel while printing is performed in the T3-period and a printing speed is not lowered.

Title: White balance adjustment circuit
Inventor: KAKIZAKI HISASHI
IPC: H04N9/73
Filed: 1990-09-20
Abstract: PURPOSE:To revise white balance while preventing deterioration in a blue projection CRT by making a gain for a blue color amplifier constant and decreasing a gain for green and red color amplifiers when a color temperature is increased and decreasing the gain of a video amplifier circuit with an ABL circuit. CONSTITUTION:When a level of a white balance control signal SW is adjusted to increase the color temperature, since the level of the control signal SW is set inversely proportional to the color temperature, the gain of red and green color VCA 4a, 4b is decreased from a white balance setting position lo, on the other hand, the gain of a blue color VCA 4c keeps that at the setting position lo because a diode Dc is cut off. Conversely, when the level of the signal SW is adjusted to decrease the color temperature, the gain of the red and green color VCA 4a, 4b keeps the gain at the state of the setting position lo because diodes Da, Db are cut off, on the other hand the gain of the blue color VCA 4c rises from the setting position lo. While the ABL is in operation, when the color temperature is increased, a blue luminance signal is increased also from the standard state. In order to suppress the increase, the ABL circuit 6 is operated by a current source 1d in which an output current is increased as the signal SW decreases to vary a DC bias of a video amplifier circuit 8 thereby limiting the luminance signal.
