Title: Vertical sawtooth wave generator
Inventor: HOSONO MASAKI
IPC: H03K4/501
Filed: 1982-06-24
Abstract: PURPOSE:To obtain a stable vertical sawtooth waveform which does not vary in DC level even when the ripple of a power supply line increases and to nearly eliminate a vertical flicker on a screen due to the ripple, by interposing a circuit with a sufficiently large time constant in a bias circuit. CONSTITUTION:The bias circuit for the base of a transistor TRQ2 has the sufficiently large time constant by a resistance R3 and a capacitor C1 and even when the voltage of a power source VCC fluctuates, the base potential of the TRQ2 is almost fixed and a TRQ1 has almost no variation in collector potential. The circuit consisting of a TRQ3, diodes D4-D6, and resistances R5 and R6 charges the capacitor C1 speedily through the TRQ3 when a power supply switch is turned on. Said bias circuit turns off the TRQ3 in a stationary state by setting the emitter potential of the TRQ3 a little bit lower than the potential at the connection point of the resistances R3 and R4, and also charges the capacitor C1 slowly when the power supply switch is turned on, so secondary operation such as lateral starting on the screen is prevented.

Title: Controlling device of hot air blowtype space heater
Inventor: KUSHIDA SHINJI
IPC: F23N5/24
Filed: 1983-06-17
Abstract: PURPOSE:To resume a normal combustion mode prior to the start of operation, by resetting a control section varying a combustion mode in response to the output of setting switch into a specific combustion mode by turning OFF a starting switch. CONSTITUTION:Upon a starting switch 1 being turned ON, a signal is inputted to a combustion control circuit to start a combustion. The output a1 of a Flip- Flop (FF) circuit 12 is then made as ''L'' and therefore a device is operated in a normal combustion mode. Upon a moderate operation switch 3 being depressed, a resultant signal passes through a chattering absorption circuit 10 to generate a specific pulse. In response, the output of FF circuit 12 is inverted into a ''H'' to establish a moderate operation. When the operation switch 1 is turned OFF under such a state, the ''L'' signal is inputted to the FF circuit 12 passing through a signal line (c) an the FF circuit 12 is resetted to generate the output of ''L''. The output of FF circuit 12 is maintained as ''L'' even when the operation switch 1 is turned ON again. The above operating procedure is the same as that of timed operation preset on a timer.

Filed: 1982-06-25
Abstract: PURPOSE:To eliminate the need for shortening a repeated period of a clock signal, and to detect effectively an abnormal pattern having minute width or length, by expanding the width of a binary-coded signal of specified width or less, and thereafter, quantizing it. CONSTITUTION:A binary-coded signal from a signal input terminal 6 is inputted to the first pulse signal generating circuit 7 and an OR circuit 8 of the first block, and the second pulse signal generating circuit 11 and an AND circuit 12 of the second block.

Subsequently, by the second block, width d2 is expanded to width (t), and outputs of the respective circuits 8, 12 are given to shift registers 13, 14. Subsequently, a clock from a clock signal generating circuit 9 is given to the registers 13, 14, and an abnormal pattern having minute width or length is detected effectively without shortening a repeated period of a clock signal.

Title: Color filter and production thereof
Inventor: KOBAYASHI ATSUO
IPC: G02B5/20
Filed: 1989-04-28
Abstract: PURPOSE:To improve characteristics and productivity by subjecting a light shielding material formed on R (red), G (green), B (blue) to etching having selectivity in a perpendicular direction and forming the light shielding material only in the spacings between R, G and B patterns. CONSTITUTION:The patterns 2 to 4 of R, G, B are formed on a glass substrate 1 and SiO2 is formed as a protective film 5 thereon.

The profiles of the formed thin films are successively transferred downward as they are according to this method and, therefore, the light shielding parts can be formed only between the patterns of R, G, B. The both of the characteristics and productivity of the color filter are improved in this way.

Title: Automatic frequency control system
Inventor: YOSHIDA NAOMASA
IPC: H04L27/38
Filed: 1990-04-25
Abstract: PURPOSE:To attain automatic frequency control without pattern jitter by using a converging signal at two points at a different time in a modulation period so as to detect a frequency error and using its output so as to compensate the frequency fluctuation. CONSTITUTION:A sampler 2 receives a signal outputted from a complex number multiplier 1 and samples a signal by a clock being four times the modulation clock and outputs sample signals S101, S102, S103 at times T/4, 3T/4, T/2 for each modulation period T. The sample signal S103 is outputted externally as a reception signal whose frequency fluctuation is compensated and filters 3, 4, 5, 6 all have a same characteristic to apply equalization to the output from a sampler 2 so as to eliminate inter-code interference. Delay means 7, 8 give a delay of a time T/2 only to a signal outputted from the filters 3, 4. A signal representing the frequency fluctuation is obtained via multipliers 9, 10 and a subtractor 11. The frequency of the output from the subtractor 11 is controlled via the loop filter 12 and a voltage controlled oscillator VCO and the result is outputted to the complex number multiplier 1 as a compensation signal. Thus, the fluctuation of the carrier frequency without pattern jitter is compensated.

Title: Liquid crystal display device
Inventor: SASUGA MASUMI
IPC: G02F1/133
Filed: 1987-05-08
Abstract: PURPOSE:To contrive the reduction of a fluctuation of the picture element potential, while preventing the drop of an effective voltage of a picture element by providing an offset level which has been set below a threshold voltage of a liquid crystal as a non-lighting level in a picture signal supplied to a signal line electrode of a liquid crystal display panel, on both positive and negative electrodes. CONSTITUTION:In a holding period in which a picture element holds a negative lighting level, a non-lighting level given to a signal line electrode has an offset -OFV. Accordingly, even in case of having an OFF resistance value of a TFT (thin film transistor) which is set to an OFF state, a voltage applied to a drain and a source of the TFT can be reduced by an offset level portion, and a leak current becomes small, therefore, the level drop of a holding voltage PXV of the negative polarity can be prevented, and an effective voltage can be made high. Also, in a negative holding period, a positive lighting level supplied to a picture element placed in other scanning line electrode becomes a voltage -V whose amplitude has become small by an offset voltage -OFV. In such a way, by coupling between the drain and the source in the TFT being in an OFF state, a noise transmitted to a picture element PX side can be reduced, and the fluctuation of the potential of the holding voltage PXV can be reduced.

Title: Vibration absorbing device
Inventor: HAYAMIZU HIROSHI
IPC: F16F9/14
Filed: 1987-05-08
Abstract: PURPOSE:To vertically fix pipes and to prevent leakage of a viscous fluid by filling up a large-diameter pipe with a viscous fluid and fitting a small-diameter pipe therein not to be sealed. CONSTITUTION:The interior of an outside pipe having the base 1 at the lower end thereof is filled up with a viscous fluid 3 of high-polymer material, and spacers 7 are fixed at several places of the outer peripheral surface of an inside pipe 6 having the top surface 5 where small holes 4 are bored at the upper end thereof. When the outside pipe 2 the inside pipe 6 are shifted in the axial direction by vibration or earthquake, shearing resistance of the viscous fluid 3 in a very small gap acts as damping force so that vibration absorbing action occurs. Accordingly, the large and small pipes are not seals, so that fixing is restricted to vertical to prevent leakage of the viscous fluid.
