IPC: H04N19/587
Filed: 1989-02-17
Abstract: PURPOSE:To evade the deterioration in a picture displayed on a monitor of a television telephone set of an opposite side just after the rising of a power supply of a camera for a sender side television telephone set by providing a fade control signal generating circuit generating a signal controlling a video signal processing circuit at the sender side. CONSTITUTION:When a control signal is inputted to an input terminal 11, a fade control signal generating circuit 12 is driven and the fade control signal generating circuit 12 sends a fade control signal to a video signal processing circuit 3. In this case, the video signal processing circuit 3 has a function applying fade control to the inputted video signal in response to the fade control signal varied from 0V to a voltage level of V1 V. Thus, remarkable deterioration in the quality of the picture on a monitor of an opposite side is evaded just after application of power supply of a camera of a television telephone set or the like by applying fade control of the inputted video signal in response to the fade control signal outputted from the fade control signal generating circuit.

Filed: 1989-02-16
Abstract: PURPOSE:To enhance storage performance and high temperature trickle charge performance by setting a length at an opposed portion, where a positive electrode and negative electrode are opposed each other, at 80% or less than that of the positive electrode. CONSTITUTION:A length at an opposed portion where a positive electrode and a negative electrode are opposed each other is set at 80% or less than that of the positive electrode.

Filed: 1978-03-29
Abstract: PURPOSE: To make unnecessary greater current source, by supplying almost equal to the base of two transistors as the gate elements through the current distribution circuit so that the current required for the hold capacitor can flow.  
     CONSTITUTION: The emitter of transistor Tr3 and the collector of Tr4 are connected to the input terminal 1, and the collector of Tr3 and the emitter of Tr4 are connected to the output terminal 2. The current distribution circuit consisting of Tr 10 and 11 is connected to the base of Tr3,4. When the switch 7 is closed with the sample hold signal to the terminal 9, the current of the current source 8 flows to the emitter of Tr 10 and 11. Since the Tr10,11 have the same base-to-emitter voltage and the same area of emitter, the current flows Tr10,11 by being almost divided into two and becomes the base current of Tr3,4. Accordingly, Tr3,4 in normal operation is sufficiently biased and the charging current requird for the sample hold capacitor 5 can flow.

Filed: 1989-02-16
Abstract: PURPOSE:To eliminate a centering while enabling highly accurate detection of oscillation by using two signals of phases A and B generated from an encoder to generate a positive pulse train or a negative pulse train. CONSTITUTION:A magnetic type encoder 11 generates two signals of phases A and B different in phase by 90 deg. from each other when a change in vibration and inclination occurs in an object to be measured, for example, a car. Shaping and amplification circuits 12a and 12b shape and amplify waveforms of the signals of two phases generated from the encoder 11 to generate signals of two phases A and B as square wave. A direction discrimination quadrupling circuit 13 generates a positive pulse train PP or a negative pulse train NP according to a direction of vibration or inclination at the rising and falling of the signals of phase A and B. Then, the positive or negative pulse is counted with counters 15a and 15b to generate positive or negative pulses continuously after the counters are reset by a reset signal. When the count exceed a set value, an oscillation detecting section 15 judges that an oscillation occurs.

Abstract: PURPOSE:To stop temporarily laser light upon detection of a local overcombustion state during cutting and to prevent formation of a rough section on the cut surface by attaching >=1 piece of detector to the condensing shaft of a laser cutting device and detecting the quantity of light at the working point. CONSTITUTION:Two detectors 8a, 8b spaced from each other at 90 deg. are attached by means of support fittings to the condensing shaft 1 for laser light to detect the quantity of the light generated from the laser working point in the stage of moving the laser light 3 condensed with a condenser lens onto a plate 4 to be worked and cutting the plate. If any combustible material such as paint, iron powder, buts and oils or the like exists on the surface of the plate 4, a local overcombustion state is generated at that point and a rough section 6 is formed in a cutting line 5. The formation of such surface is prevented by detecting the quantity of the light in the working part which is increased several times by the detctors 8a, 8b, stopping temporarily the emission of the light 3 in accordance with the detection signals thereof and restarting the cutting by the laser light after the cut surface cools. The successive formation of the section 6 is thus prevented.
