Title: Image signal quantizing device
Inventor: NISHI TAKASHI
IPC: H04N1/41
Filed: 1993-05-06
Abstract: PURPOSE:To prevent an image from deteriorating even when the level of a luminance signal is high by properly selecting step sizes for quantization of both the luminance signal and a color difference signal. CONSTITUTION:Before the step size for quantization of the color difference signal is determined, a luminance signal level detection part 11 detects the mean signal level of the luminance signal. Further, a color difference signal step size control part 12 sets the step size of the color difference signal previously corresponding to the mean signal level of the luminance signal. A color difference signal quantization part 4 quantizes the color difference signal by a small step size on a bright screen where the mean signal level of the luminance signal is high and by a large step size on a dark screen. Thus, the image signal is prevented from deterioration in quality.

Title: Optical scanning recorder
Inventor: NOZAKI NOBUHARU
IPC: G02F1/335
Filed: 1988-05-27
Abstract: PURPOSE:To stabilize the quantity of recording light and to increase the modulation speed by using an electrooptic modulator which modulates a light beam incident on a surface acoustic wave. CONSTITUTION:An optical deflector 10 has a slab type optical waveguide 11 formed on a transparent substrate 16, an interdigital electrode couple (IDT) 15 provided to a side end part of the optical waveguide 11, an electrooptic grating (EOF) 14 as the electrooptic modulator, a linear diffraction grating (LGC) 20 for light incidence, and an LGC 21 for light projection. Consequently, variation in the wavelength of the recording light due to direct modulation on a semiconductor laser 18 as a recording light source can be prevented, so the variation in the quantity of the recording light caused by this wavelength variation is prevented to record a highly fine image of high picture quality. Further, the state of voltage application to the optical modulator is changed and then the modulation state of the light beam changes instantaneously, so the modulating speed can be increased.

IPC: C30B29/30
Filed: 1978-10-25
Abstract: PURPOSE: To easily produce a high quality, large size single crystal by relatively changing the position of a crucible and the heating zone of a heater so that a single crystal is grown while holding the power consumption of the heater almost constant, thereby minimizing changes in furnace temp. conditions due to a melt level lowering.  
     CONSTITUTION: Sintered raw material such as LiTaO 3  is put into Pt-Rh crucible 1 and melted by high frequency heating with a heater such as work coil 10. At this time, coil 10 is previously set so that central position A of the heating actual length of coil 10 coincides with central position B of the depth of crucible 1. A single crystal is then pulled from the molten material at a fixed rate with a LiTaO 3  seed crystal of X axis direction. When the pulled crystal reaches a predetermined diameter, the relative position between crucible 1 and coil 10 is changed to grow the crystal while keeping the diameter. By holding the power consumption of coil 10 almost constant, changes in furnace temp. conditions due to a melt level lowering are minimized.

IPC: H03K5/08
Filed: 1979-10-09
Abstract: PURPOSE:To enable binarized reproduction of the signal of low amplitude level in analog signals, by taking a voltage variable resistance element as a nonlinear generating means and adding it to a superposition signal generating means. CONSTITUTION:A DC bias signal Ed and an analog signal Ep are obtained at both ends of a variable resistor VR1 as a superposed signal. This superposed signal is fed to a nonlinear generating means consisting of a voltage variable resistance element D1 and a resistor R6. In this case, the operating point Vp of the voltage variable resistance element D1 is set to a value corresponding to the DC level of the compared voltage level. Thus, the voltage variable element is at off-state at higher voltage by setting the operating point of the element D1. On the other hand, in the range near the peak voltage Vp, this voltage variable resistance element acts like a variable resistor and shows a low impedance near the peak voltage Vp especially. Accordingly, the parallel synthesized resistance between the variable resistor VR1 and this nonlinear generating means 3 is formed, the terminal voltage of the variable resistor VR1 is depressed down, and the white information of low amplitude in the black level can be reproduced.

Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To detect the abnormal rotation of a workpiece, without adding a device for detecting rotation. SOLUTION: A rotation period to be a standard is calculated from the number of revolutions of a main spindle for fixing a workpiece (S12). The diameter of the workpiece is measured (S14) and it is judged whether the diameter of the workpiece is changed from decrease to increase (S18). When the diameter of the workpiece is changed from decrease to increase (S18 is YES), the rotation period (deflection period) of the workpiece is calculated from a held data (S20). In other wards, the rotation period of the workpiece is found out based on the interval between the minimum value of the deflection and the maximum value. Thereafter, the deflection period is compared with the standard rotation period and when this difference is beyond an allowable value (S22 is YES), it is judged to abnormal and an abnormal rotation is informed (S24).

Abstract: PURPOSE:To remove the remaining frost after the completion of defrosting operation and thereby improve the capacity of heating, by setting the defrosting operation end temperature for the next defrosting operation to a higher temperature when an outdoor heat exchanger drops below the setting temperature within the setting time from the heating reset time. CONSTITUTION:Within a required setting time from the heating operation reset time, a defrosting operation end setting temperature change means 20 reads constantly the temperature of an outdoor heat exchanger 5 by way of an outdoor heat exchanger temperature sensor 8 and a controller 7. Furthermore, the defrosting operation end setting change means 20 changes the defrosting operation end setting temperature predetermined by the controller 7 to a higher temperature when it is detected that the read temperature drops below the setting temperature. Therefore, the next defrosting operation is operated until the temperature of the outdoor heat exchanger 5 reaches the defrosting operation temperature higher than the previous operation. As a result, the temperature of the outdoor heat exchanger 5 is higher, thereby enabling eliminating the remaining frost 11 substantially. It is, therefore, possible to improve the heat exchanging power of the outdoor heat exchanger 5 and upgrade the heating capacity as well.
