Abstract: A provisional temperature estimating mathematical expression is set in accordance with which plasticizing conditions used as terms are to be multiplied by unknown coefficients. Then, a given number of experiments not smaller than the number of the unknown coefficients are conducted while the plasticizing conditions are varied, so as to acquire various experimental data. The unknown coefficients are converted into known coefficient in accordance with the acquired experimental data so as to provide a complete temperature estimating mathematical expression, on the basis of which a plasticized resin temperature and noise-outlet resin temperature are determined arithmetically.

Abstract: An ultralow expansion brake rubber hose comprising an inner rubber tube, a first reinforcing layer, a second reinforcing layer and an outer rubber layer, wherein a thermosetting resin which penetrates the reinforcing fibers constituting the first reinforcing layer and which is cured at vulcanizing temperatures is cured by vulcanization to turn the first reinforcing layer into a solid cured layer. By turning the first reinforcing layer into the solid cured layer, the mutual slippage between the reinforcing fibers of the first reinforcing layer can be prevented, and a brake rubber hose having low expansion and excellent durability can be obtained.

Abstract: Molding conditions of an injection molding machine are set through performance of virtual molding by CAE. First, actual molding is performed under provisional molding conditions in order to obtain an actual profile showing variation in load pressure actually measured during at least an injection step of the actual molding. Further, virtual molding is performed by CAE under the provisional molding conditions in order to obtain a virtual profile showing variation in load pressure simulated during at least an injection step of the virtual molding. The provisional molding conditions are changed by CAE in such a manner that the virtual profile coincides with the actual profile, to thereby obtain intermediate molding conditions. Subsequently, the intermediate molding conditions are optimized so as to obtain molding conditions for the injection molding machine.

Abstract: In a frequency dividing circuit, a VD pulse is generated as a vertical synchronization signal on the basis of the bus clock inputted from an external circuit, while in the gate circuit, integral circuit, gate circuit and hold circuit, the frequency of bus clock is detected on the basis of the VD pulse. Moreover, in the PWM circuit, when the frequency of the bus clock is high or low, a shutter drive pulse having the width shorter or longer than that in the related art is generated, respectively. The electronic shutter driver closes the electronic shutter of the CCD imager (charges generated in the CCD imager are discharged) for the period corresponding to the shutter drive pulse. Thereby, the discharging period in the CCD imager is fixed to a constant period without relation to the frequency of the bus clock. Accordingly, an image having adequate luminance can be obtained by the so-called multi-scan type image sensing device.

Abstract: A control circuit for a DC capstan motor used for driving a tape having control signals thereon is adapted for accurate stopping of the tape during intermittent-motion operation. A frequency generator coupled to the motor generates a frequency signal whose frequency is proportional to the motor's speed. A position signal generating circuit generates a position value that increments by steps upon occurrences of the frequency signal. A clamp circuit clamps the position value to a clamping level upon detection of the control signals. A brake start signal generator provides a brake start pulse signal when the position value exceeds a predetermined threshold, and this brake start pulse signal is used to commence braking of the motor. In order to permit accurate stopping in both forward and reverse directions, the clamping circuit provides one clamping level when a forward mode is selected and another clamping level when a reverse mode is selected.
