Title: Strip rolling mill
Inventor: YOSHIHARA SEISHIROU
IPC: B21B1/22
Filed: 1984-07-10
Abstract: PURPOSE:To reduce the size of a small-diameter work roll and to make possible high-draft rolling by providing pressure grasping devices which grasp the small- diameter work roll under the pressure. CONSTITUTION:The pressure grasping devices 9, 10 which grasp the small- diameter work roll 31 under the pressure are provided and the roll 31 is grasped under the pressure by reinforcing rolls 5, 6 from the front and rear directions. Large-diameter work rolls 1, 3 are driven in the same direction and since the roll 31 is not-driven, the roll is limited from the limitation in torsional rigidity. Since said roll is grasped and held under the pressure by the rolls 5, 6, the roll is released from the limitation in bending rigidity. The diameter is thus considerably reduced and the high-draft rolling is made possible.

Title: Image pick-up tube
Inventor: KOMURO YOSHIYUKI
IPC: H01J29/89
Filed: 1980-10-09
Abstract: PURPOSE:To take the stabilized highly accurate dark current component by smoothing the surface of a color separation filter layer through an organic smooth layer while providing an optical black on said surface and bringing the optical black close to the transparent electrode. CONSTITUTION:An organic smooth layer 16 is formed on color separation filters 2R, 2G, 2B formed on a transparent substrate 1 to smooth the surface. Since the adhesive layer and the glass film placed between the optical black 20B and the transparent electrode 4 are made removable to bring them closely, the light incident to the substrate 1 with the angle other than the right angle will not cause the incident light of the color component to the transparent electrode 40B. Consequently the transparent electrode 40B of the optical black 20B is prevented from the unnecessary incident light thereby the stabilized highly accurate dark current component can be taken out.

Title: Demagnetizing device
Inventor: YOSHIDA KAZUHITO
IPC: H01F13/00
Filed: 1990-05-31
Abstract: PURPOSE:To prevent an object to be demagnetized from being bounced out of coils by inclining the axes of the coils at a predetermined angle with respect to a vertical direction. CONSTITUTION:A magnetized runner 9 produced by molding is guided by a shooter 3 to be fed into a cylindrical body 1 and set on a discharge shutter 5. Then, by cling a switch 12, a capacitor 11 is charged by a charging circuit 13 and, by closing a discharge switch 14, the capacitor 11 generates electric discharge, whereby the alternating current flows through coils 2 by the oscillation phenomenon of an LC circuit. The amplitude of the oscillation of the current is naturally damped due to a loss of the current caused by a resistor R and, as a result, a damping alternating magnetic field is applied to the runner 9 to perform demagnetization. A force F assuming an angle theta' with respect to the center line Z of the cylindrical body 1 is applied to the runner 9, which is thereby accelerated and moved toward a central part in the direction of the height of the coils 2. The supply of the current flowing through the coils is stopped before the runner 9 reaches the central part in the direction of the height of the coils 2, and the demagnetization of the runner 9 is completed.

Title: Digital automatic gain controller
Inventor: HIRANO MIHOKO
IPC: H03G3/30
Filed: 1989-06-05
Abstract: PURPOSE:To generate a stable gain so as to allow a voice data to receive more natural level adjustment by using a gain coefficient outputted to a multiplier based on an output of a voice detector as a sample when a digital signal represents no sound state. CONSTITUTION:A level of a digital output signal X is extracted by a square circuit 61, an adder 62 and a delay circuit T2 average the level and a multiplier 66 gives a weight of b' to the averaged level. Then the result is compared with a noise threshold level C set separately at a comparator 63 to decide whether the data represents a voiced sound or no sound. The result is sent to a selector 64 provided between an adder 42 and a delay circuit T1. The selector 64 allows a switch 65 to be thrown to the position of ON when an input signal X represents a voiced sound based on the output of the comparator 63 thereby forming a loop for averaging. Moreover, the selector 65 allows the switch 65 to be thrown to the position of OFF when the input signal X is decided to be no sound. Then natural voice signal level adjustment is attained.

Title: Semiconductor laser device
Inventor: SHIMADA JUNICHI
IPC: H01S5/00
Filed: 1991-05-20
Abstract: PURPOSE:To enable a semiconductor laser device to be lessened in size and weight. CONSTITUTION:Laser rays emitted from a semiconductor laser 1 are made to impinge on a lens 4. The lens 4 is possessed of a curved surface, so that it converts the incident laser rays into convergent rays in parallel with a semiconductor substrate. The lens 4 has a distribution of refractive indexes in the thicknesswise direction, but it has a small aperture, so that it can be focused outside of a laser ray projecting window 3. Therefore, laser rays diverging from the lens 4 are converted into parallel laser rays vertical to the semiconductor substrate once, and then the parallel laser rays are converted into convergent rays through the curvature of the laser projecting window 3 in the direction vertical to the semiconductor substrate. By this setup, as mentioned above, when the projected light rays from a semiconductor laser device are effectively used, the light rays can be outputted as convergent rays or parallel rays without using an additional lens, and thus the device concerned can be lessened in size and weight and enlarged in application for various fields.
