IPC: G09G1/16
Filed: 1990-10-22
Abstract: PURPOSE:To correct the parallelogrammic distortion on a screen by adding a vertical saw tooth wave component to a horizontal deflecting circuit to continuously change the phase to the horizontal synchronizing signal of the output pulse of a horizontal oscillating circuit in each vertical period. CONSTITUTION:When a vertical deflecting saw tooth wave current flows to a vertical deflecting yoke VDY, a saw tooth wave voltage is generated at the connection point of resistances RA and RB. This voltage has the DC component cut by a capacitor C7 and is inputted to an operational amplifier IC2. The output of the amplifier IC2 is inputted to a horizontal AFC circuit, and the output is not a DC but has a vertical saw tooth wave component. The phase of the pulse at an output terminal (OUT) of the horizontal oscillating circuit is continuously changed from the top to the bottom of the screen in accordance with this vertical saw tooth wave component, thus correcting the parallelogrammic distortion.

Filed: 1990-10-24
Abstract: PURPOSE:To prevent the hanging-up of a reception-side computer so that semi- duplex communication can be continued by enabling the reception-side computer to refuse the storage of an abnormally long text even when the text is sent from a transmission side. CONSTITUTION:When an abnormally long text is transmitted from a transmission-side computer 1 to a reception-side computer 2, an input byte number discriminating means 5 discriminates that the number of input bytes is larger than a set number of bytes and a storage stopping means 6 stops data storage in a storing means 3 in response to the discriminated result of the means 5. As a result, the normal operation of the computer 2 is secured, because the hanging-up of the computer 2 is prevented, and a reception terminating signal output means 4 can output a reception terminating signal to the transmission-side computer 1 in response to a text punctuating signal. Therefore, the transmission from the computer 1 is not discontinued and the semi-duplex communication can be continued.

Title: Receiver
Inventor: WATABE HIDEJI
IPC: H03G3/32
Filed: 1992-10-22
Abstract: PURPOSE:To exactly detect the intensity of an input signal by providing a received field intensity signal based on only the level of an IF received signal separated by an IF filter. CONSTITUTION:When tuning is shifted between the frequency of the IF received signal and the frequency of a tuning circuit 3 by fluctuation in the frequency of a local oscillator(OSC) 10 or the like and the IF received signal gets out of the pass band of an IF filter 5, the level of the IF received signal is attenuated by the filter 5. Therefore, the level of a first control signal is attenuated to a value lower than a thershold value 14, and a switch 12 is turned to a non-conductive state by a comparator 11. Thus, the first superimposing of a second control signal is blocked, the level of a signal intensity detecting output 101 is almost turned to '0' and an output characteristic without level shift is provided. Therefore, even when a strong disturbing wave exists in an adjacent frequency when the intensity of the input signal is weak, the intensity of the input signal can be exactly detected.

SOLUTION: A register 1 into which a base vale 1 is filled and a register 2 into which a base value 2 is filled are provided. The values are subtracted by a subtracter 3. A specified bit among the output bits is inputted to an NOR circuit 4. If the value X to be evaluated is an integer which satisfies 0<=X<=2N and which is binary-displayed when the reference value is a positive integer being the certain numbered power of '2', '1' is generally given only between the first digit and N-th digit, which are counted from a digit at the lowest location, and the digit at higher location than the (N+1)-th digit becomes '0'. If '1' is outputted from the NOR circuit 4 when the digit at higher location than the (N+1)-th digit is inputted to the NOR circuit among the outputs of the subtracter 3, it is judged that 0<=×2N.

The surface layers consists of a mixture phase of three or more oxides. Then the lubricant layer 7 is provided on the ferromagnetic metal thin film 6. By constituting the surface of the mixture phase of plural numbers of oxides, the surface layers hardly coagulate to a magnetic head and are free from partial fractures caused by movement of coagulation particles. Thus, the obtained medium has excellent durability under large stress.
