Title: Luminance signal/chrominance signal separating circuit
Inventor: USUKI NAOJI
IPC: H04N9/64
Filed: 1992-07-08
Abstract: PURPOSE:To improve luminance drop and cross color in a high frequency non- correlating part of a luminance signal. CONSTITUTION:A high frequency component is separated from a composite video signal by a band pass filter(BPF) 5 and delayed through 1H delay circuits 6, 7 and plural signals 0H, 1H, 2H close to each other in the vertical direction are synchronized with each other. After inverting the 0H and 2H signals by respective inversion circuits 8, 9 and converting the inverted signals into the pattern spaces of a chrominance signal, a center value is logically computed by a logical operation circuit 10. The center value is added to the 1H signal by an adder 11 to obtain a carrier chrominance signal. In the state that the 0H, 1H and 2H signals are held at the pattern space of the luminance signal, the center value is logically computed by a logical operation circuit 14. The center value and the 1H signal are mutually subtracted by a subtractor 15 to obtain a carrier chrominance signal. A switching circuit 17 switches the outputs of the adder and the subtractor 15 in accordance with a correlation detecting circuit outputted from a correlation detecting circuit 16 and the selected output is outputted to a chrominance signal output terminal 13.

Filed: 1981-11-11
Abstract: PURPOSE:To prevent the generation of an abnormal tone due to the disorder of a waveform, etc., by generating a muting signal in a power-off state, and cutting off a signal input to a signal processing circuit in response to the muting circuit. CONSTITUTION:If a power switch 6 is turned off while an IC2 for amplification powered up by a power source 4 amplifies an input signal from a signal source 12 to supply the resulting signal to a speaker 18, a capacitor 8 for a ripple filter is discharged and a capacitor 28 for a time constant circuit is also dischrged to develop a voltage across a resistance; and a potential detecting circuit 24 detects it to generate a muting signal, which turns on an input cutting circuit 22 to cut off the input signal from the signal source 12. A signal processing circuit prevents the generation of an abnormal signal securely when the power source is turned off, and audio equipment prevents the generation of a uncomfortable tone in a power-down state.

Title: Liquid crystal display device
Inventor: MORIWAKI HIROYUKI
IPC: G02B5/30
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device which has high lightness and high contrast and can be made paper-white. SOLUTION: The upper polarizing plate 10 of a couple of polarizing plate between which a liquid crystal cell 1 is sandwiched polarizes incident light into a reflected and a transmitted component. Thus, light which is absorbed when a high polymer dichroic polarizing plate is used is utilize as reflected light to improve the lightness. The lower polarizing plate 6, on the other hand, polarizes the incident light into an absorbed and a transmitted component. Thus, the reflected light from the lower polarizing plate 6 is eliminated to evade a decrease in contrast due to the reflection of the reflected light from the lower polarizing plate 6 by the upper polarizing plate 10. The upper polarizing plate 10 has flat spectral characteristics to reflected light and transmitted light and chromaticness index a* and b* are both <=1.  Neither the reflected light nor the transmitted light of the upper polarizing plate 10 is colored to easily obtain paper-white display.

Title: Page printer controller
Inventor: TAKAYORI MASAYA
IPC: G06F3/12
Filed: 1989-07-12
Abstract: PURPOSE:To attain high speed throughput even with the small memory capacity by using effectively an idle area of a storage means and processing the print output and the evolution of the bit map data on the next page in parallel with each other. CONSTITUTION:An evolving means 12 reads the document data on the first page out of a document data buffer 11 and converts the data into the bit map data to evolve it to a print buffer 13. An output means 14 starts the output of the contents of the buffer 13 to a printer 15 under the control of an output control means 16. Then the means 12 knows via a print pointer 17 that the bit map data on the first page is outputted up to its middle point and then reads the document data on a second page out of the buffer 11. This read data is also converted into the bit map data and evolved to the buffer 13. Thus an idle area of a storage means is effectively used and both the print output and the evolution of the bit map data on the next page are carried out in parallel with each other. As a result, the document can be printed at a high speed even with the small memory capacity.

The diffuse plate 6 is off contact from the device body electrically, and the surface is charged, for ex., at 3-5V to trap the secondary electrons b generated at the diffuse plate 6 for the secondary electron sensor 5 not to catch them. Thus the picture quality is enhanced by trapping the secondary electrons b and reducing the secondary electrons due to reflex electrons which have made reincidence by the specimen X.

Title: Air conditioner
Inventor: KOJIMA YOSHINOBU
IPC: F24F11/02
Filed: 1984-08-31
Abstract: PURPOSE:To operate in high load and high capacity by forming the output voltage waveform of a frequency converter and similar sinusoidal wave PWM waveform in a constant torque range, and a filter wave in the constant output range to rise an effective voltage. CONSTITUTION:A controller 5 receives an output from an air conditioning load detector 6, decides the frequency in response to the load, and outputs the waveform signal corresponding to the frequency to an inverter 2b. It is operated in similar sinusoidal wave PWM waveform in the range A, and in the filtered waveform in the range B. When it is thus switched from the similar sinusoidal PWM wave to a rectangular wave, the effective voltage of reversely converted AC can be raised. On the other hand, since a motor 4 for driving a compressor 3 is used as an induction motor, when the applied effective voltage is raised, the generated torque rises, and the current decreases, thereby reducing the heat of the motor.
