Abstract: PURPOSE: To make the conc. of a sulution reach the highest concn. in the final stage and to avoid scaling in a falling-film evaporator by bringing the vapor into direct contact with the soln. flowing down in a heating zone. CONSTITUTION: The final evaporating stage includes three falling-film evaporators, the black liquor contg. 45% dry substance coming from a preevaporator is supplied from a pipeline 1, the liquor contg. 55% dry substance is supplied to an evaporator B from a pipeline 15, and the liquor contg. 67% dried substance is supplied to an evaporator C from a pipeline 19. The liquor in a pipeline 20 contains 75% dry substance. In order to attain the above concn. the live stream at 145 deg.C is supplied to the respective evaporators from a pipleine 4, and the saturated vapor at 116 deg.C is discharged from a pipeline 11. The saturated vapor in the pipelines 16B and 16C is kept at 115 deg.C. The vapor temp. difference between the evaporator A and the evaporators B and C is continuously obtained from the pressure drops in the pipelines 11, 11B and 11C.

IPC: H04N5/60
Filed: 1993-10-19
Abstract: PURPOSE:To prevent sound mode switching from being erroneously operated by ANDing the output signals of a control signal extracting means and a sub carrier wave extracting means and masking noise from the control signal extracting means at the time of monaural signal broadcasting. CONSTITUTION:The output signals of a monostable multivibrator circuit 18 and a logic refusal circuit 9 are ANDed by an AND circuit 10 and at the time of monoral sound broadcasting, a monaural sound mode discriminate signal is outputted from an output terminal 15. On the other hand, the output signals of the circuit 10 and a logic refusal circuit 11 are ANDed by an AND circuit 13 and at the time of stereo sound broadcasting, a stereo sound mode discriminate signal is outputted from an output terminal 16. Further, the output signals of the circuit 10 and a logic refusal circuit 12 are ANDed by an AND circuit 14 and at the time of bilingual sound broadcasting, a bilingual sound mode discriminate signal is outputted from a terminal 17. When inputting a composite sound signal in which much noise is contained, no sub carrier wave is transmitted at the time of a monaural mode, the noise component passed through a band pass filter 5 is masked by an AND circuit 6, and a frequency comparator 8 is not erroneously operated.

Title: Hologram, and method and device for confirmation using the same
Inventor: MORITA HIDEAKI
IPC: G03H1/22
Filed: 1992-09-30
Abstract: PURPOSE:To remarkably improve a forgery prevention effect, to improve working efficiency for reading, and to improve objectivity for truth/falsefood confirmation by recording a hologram image with aberration, and changing a reproducing pattern by a focal position. CONSTITUTION:A hologram 1, mounted on a card 2 is, for example, a computer generated hologram, and the hologram image whose diffracted light spot shape is changed by the focal position is recorded on it. When the hologram 1 is irradiated with reproducing light from a light source 3, and a sensor position is changed or the position of the light source is changed, a spot 4 with aberration is changed to spades, diamonds, and hearts like, for example, the pattern 5. The forgery prevention effect can be remarkably improved by recording such changing pattern in advance, and discriminating the truth/falsehood.

Title: Protective device of power transistor
Inventor: ISHIKAWA FUKUO
IPC: G05F1/56
Filed: 1993-10-20
Abstract: PURPOSE:To surely protect a power transistor after excess current is decided by exactly deciding the excess current flowing in the power transistor without being affected by noise. CONSTITUTION:In a device where charging/discharging circuits (CO 1, TR 2, IN 1) generating oscillation signals by the charging/discharging of a capacitor C 0 are provided and a power MOSFET 16 is turned on based on the oscillation signal at the time of charging the capacitor C 0, a transistor TR 3 is turned off and the upper limit voltage at the time of charging the capacitor C 0 is changed to a larger value than a normal one when a comparator CO 2 decides the excess current of the FET 16. Whether the both end voltage of the capacitor C 0 is more than decision voltage which is larger than normal upper limit voltage or not is decided by the comparator CO 3. If the voltage is more than the decision voltage, the FET 16 is turned off and the charging of the capacitor C 0 is continued. As a result, the turning off of the FET 16 is eliminated by the erroneous decision of excess current and the state can be surely held after the FET 16 is turned off.

IPC: G11B5/31
Filed: 1984-12-13
Abstract: PURPOSE:To attain the high density arrangement of coils by specifying the shapes of the coils under two-channel constitution. CONSTITUTION:A pair of spiral coils are flatted in the adjacent direction 21 and the medium sliding surface direction 22, and at the center of respective coils or the intersecting point of straight lines parallel and vertical to the medium sliding surface and the conductors of respective coils, the conductors of the respective coils are intersected with said straight lines at right angles. In addition, the conductors of the respective coils are intersected with a straight line 23 obtained by connecting the center of the coils with the center between the tracks on the sliding surface 19 at approximately right angles. Consequently, two-channel heads having short magnetic path length can be arranged with high density and the volume of winding can be increased due to the flatting of the coils. Since the distances of the adjacent opposed part of magnetic cores consisting of upper and lower magnetic layers from the adjacent coils are separated, low crosstalk is obtained.
