IPC: B22D11/06
Filed: 1983-10-28
Abstract: PURPOSE:To improve the quality and yield of a billet by measuring actually the pouring rate of a molten metal into a small tundish, controlling the opening degree of a sliding nozzle so as to make said rate coincident with the target inflow rate for charging according to the measured pouring rate and determining the drawing speed of a caster from the pouring rate after the control. CONSTITUTION:The weight of a molten metal 2 charged from a large tundish 4 into a small tundish 5 is measured by a load cell 14 attached to the tundish 5 prior to starting charging of the molten metal 2 into a belt type continuous casting machine. The flow rate for pouring of the molten metal 2 is calculated from the time change value of said weight and the opening degree of a sliding nozzle 6 is controlled to make said rate coincident with the target charging rate. The pouring flow rate after the control similarly calculated and the respective initial drawing speed and stationary drawing speed in the respective stages of initial operation and succeeding stationary operation of the belt type continuous casting machine are determined from the calculated flow rate to detect the start of charging and at the same time the operation is performed at the initial drawing speed then at the stationary drawing speed.

Filed: 1993-08-17
Abstract: PURPOSE:To provide a display device capable of changing display colors on a light emitting surface easily and in various ways and improving remote visibility without any structural changes when display colors are changed. CONSTITUTION:A lighting control signal is sent by a driver control circuit 12 to a driver 13 so as to alternately light, for example, red and green LED 1 and 2, to be dynamically controlled at a high frequency based on a control signal from a pulse width control circuit 14 for controlling the frequency and pulse width of a lighting signal. Then, by the lighting signal from the driver 13, the control of the LED having a longer lighting period is intensified because of an after image phenomenon and the display colors on the light emitting surface are made variable by its duty ratio. For example, a blue LED 11 is turned OFF and the red and green LED 1 and 2 are turned ON by the duty ratio 50%, the display color on the light emitting surface via a filter 3 is made orange and by shortening the pulse width of the red LED 1 and lengthening that of the green LED 2 the emitted light is made yellow.

IPC: G06F17/28
Filed: 1992-07-30
Abstract: PURPOSE:To translate a sentence even of a compound sentence in original language as target language of a simple sentence by converting a structure to the simple sentence of a structure in which a noun phrase subjected to structure conversion is embedded as the subject of a principal clause subjected to structure conversion, and generating a target language sentence, based on the simple sentence. CONSTITUTION:Original language inputted from an input part 1 is analyzed to an original language structure by an analyzing part 2, and thereafter, whether it is a compound sentence or not is decided by a converting part 3. In the case it is a compound sentence, whether its connection is a cause/reason connection or not is decided. Whether it coincides with a converting condition or not is decided, and when it coincides therewith, it is converted to a target language structure. Target language is obtained in a generating part 4, and a target language sentence is outputted from an output part 5. That is, in the case the connection does not coincide with the converting condition, a principal clause and a subordinate clause are translated to the target language, respectively, and thereafter, a version obtained by connecting the translated principal clause and subordinate clause by a connecting word of the target language for showing the cause/reason is outputted. In such a way, a sentence whose original language is described by a compound sentence can be translated as the target language of a simple sentence.

Filed: 1983-10-31
Abstract: PURPOSE:To hold the amount of toner in a cleaner invariably optimum by varying a voltage impressd to a toner recovery electrode according to the amount of toner sticking on the electrode. CONSTITUTION:An attracting roller 10 comes into slide contact with a cleaner 8 on a sleeve 7 while rotating to attract and remove the toner from the cleaner 8. A variable bias power source 11 is connected to the attracting roller 10 and impresses the roller 10 with a bias voltage E2 having the polarity opposite to that of the charge of toner on the sleeve 7. In this case, the bias power source 11 varies the bias voltage E2 according to the amount of toner in the cleaner 8. The toner in the cleaner 8 is not attracted by the attracting roller 10, but the amount of toner attracted and stuck on the surface of the attracting roller 10 varies with the amount of toner in the cleaner 8. Therefore, the amount of toner stuck on the surface of this attracting roller 10 is detected to know the amount of toner in the cleaner 8.

Title: Winding method of adhesive sheet
Inventor: KONUMA SHIGERU
IPC: B65H23/198
Filed: 1990-07-31
Abstract: PURPOSE:To minimize the influence of cross directional unevenness or fluctuation of tension in the winding start time having a small winding diameter and unstable winding state by applying a winding tension larger than that in steady winding time for a fixed time of winding start, and gradually lowering it to the steady winding tension. CONSTITUTION:In the winding start time having a small winding diameter and unstable winding state, a winding tension T is kept high for a fixed time  t1. Thereafter, it is gradually lowered to a normal tension T1. Thus, even if the tension T is uneven or fluctuated, its influence is minimized, and by conducting winding in the state where a support body is strongly pulled, it is made difficult to generate cross directional and longitudinal wrinkles or oblique winding.

Title: Bias magnetic field impressing device
Inventor: TERASAWA TAKESHI
IPC: G11B11/105
Filed: 1988-08-17
Abstract: PURPOSE:To reduce heat generation and current consumption by equipping the title device with a permanent magnet to generate a magnetic field having a direction to negate another magnetic field from a magnet for an actuator. CONSTITUTION:Actuators 7 and 7, which are driving means to move a lens 5 in a diameter direction and a vertical direction, are provided for the circumference of a lens 5. Further, a core 2 is provided for the upper surface side of a disk medium 4, and a coil 1 is wound around the center part of the core 2. Further, bar-shaped permanent magnets 3 and 3 are provided for the lower side of the coil 1, and the intensity and the directions of the magnetic fields of the permanent magnets 3 and 3 are determined so that the magnetic fields can negate the magnetic fields of magnets 7b and 7b for the actuators. Consequently, since the magnetic fields from the magnets 7b and 7b for the actuators to compose the actuators 7 and 7 to drive an objective lens are negated by the permanent magnets having polarity having an opposite direction to that of the polarity of the magnets 7b and 7b, the influence of the magnets for the actuators can be removed. Thus, it becomes unnecessary to impress an additional bias magnetic field for negating a leakage magnetic field, and the heat generation and the current consumption can be reduced.
