Abstract: PURPOSE: To ensure an easy adjustment of the temperature compensation by combining the temperature dependent voltage generating circuit and the logic circuit featuring the gate function controlled by the output voltage of the above mentioned voltage generating circuit and then controlling the frequency of the oscillator circuit with use of the logic circuit.   
     CONSTITUTION: The power source voltage +B is converted to the stable reference voltage  through constant voltage diode 21 and then converted to the ambient temperature dependent voltage by resistance 22 and thermistor 23. This voltage is then divided by resistors 24, 25, 26 and 27  to be applied to NAND circuit 30 and 31. As the stable reference voltage is applied, the output of  circuit 30 and 31 feature low levels in the case of the level of over the threshold voltage. With  increment of the ambient temperature, the input voltage is converted to the stepped voltage of  under the threshold voltage to be applied to one end of variable capacity diode 34, with the other  end receiving application of the stable voltage. Thus, the frequency change caused by the temperature fluctuation of the voltage control voltage oscillator comprising piezoelectric oscillator and  others can be compensated. The dispersion caused by the frequency temperature characteristics of  the oscillator or the like can be controlled by variable resistor 36.

IPC: H04L7/08
Filed: 1987-03-18
Abstract: PURPOSE:To perform an accurate transition in a short period by controlling the transition between a synchronism set-up state and a set-out state based on the detecting result of a frame synchronizing flag and the error checking result obtained based on a frame error check code. CONSTITUTION:A CRC calculation part 15 calculates a new frame error check code from the given frame synchronizing flag and the data on an information part and stores the code into a buffer A14. A comparator part 16 compares said frame error check code with a received one and gives the result (coincidence or discordance) of comparison to a frame synchronism protecting part (NEW) 11. In a synchronism set-up state, a channel separating part 8 sends the separated data as it is. While the part 8 mark-holds the data in a step-out state. Thus the detecting time is shortened for both step-out and synchronism set-up states together with sure detection of both states.

IPC: H04N7/50
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To reproduce the fine part of a picture with good quality by adding a slight weight to the transformation coefficient value of the picture when the picture moves a lot and transmitting only a changed part from a preceding picture when the picture is still or moves little. SOLUTION: Each picture is divided into the blocks of point sets, bi-directional transformation is applied to the function of the value of a block to generate the value of a matrix expressing a spatial frequency called the transformation coefficient of the block. Then at the time of displaying a scene in which the picture moves a lot and transmitting the value of transformation coefficient of this picture, a slight weight is added to a coefficient corresponding to an intermediate or high spatial frequency. On the other hand, when the picture moves little or is still, only the changed part concerning the preceding picture of a picture fluctuation coefficient is transmitted. Then the movement of the picture shown by consecutive pictures is evaluated by comparing the value of the transformation coefficient of the corresponding block of each picture.  Thereby, at the time of displaying a picture of little movement or a still picture, the redundancy of information in the picture is utilized to reproduce even the fine part with good quality.
