Title: Repeater
Inventor: KUNITOU KENICHI
IPC: H04B7/185
Filed: 1984-03-30
Abstract: PURPOSE:To decrease the frequency error between intermediate frequency signals by using a signal as a result of mixing between a signal of the 1st local oscillator used in common and a signal multiplying a signal of the 2nd local oscillator by (1-n) to mix the resulting signal with a reception frequency at n- set of reception sections. CONSTITUTION:Frequencies f1-fn are assigned to plural reception antennas 19- 22 so as not to be overlapped with each other. Outputs of each antenna are inputted to reception sections 23-25. A common frequency F1 of another oscillator 33 is fed while multiplying it with multipliers 34-36 by (1-n) times, subjected to mixing (29-31) to form local oscillating frequencies fLO1-fLOn, which are mixed with the reception frequencies f1-fn and then the result is converted into an intermediate frequency fIF. The oscillating frequency F1 is set to the vicinity of the local input frequency of the mixers 26-28, the frequency of the multipliers 34-36 corresponds to the difference between the local input frequency and the frequency F1 of the mixers 26-28 and such frequency is to be obtained by maltiplying the common output frequency of the oscillator 33 by an integral number of multiplication. Thus, the intermediate frequency with less deviation is obtained to attain ease of demodulation.

Title: Printing control method
Inventor: IZUMI HIROSHI
IPC: G06F3/12
Filed: 1989-03-17
Abstract: PURPOSE:To shorten the time required for the development of a bit pattern and to increase the printing speed by forming the capacity of a buffer in order to store up to the final dot of a character font when one character font covers the twice printing range, thereby omitting the need to develop the same character font twice. CONSTITUTION:A buffer has the capacity equal to the number of dots smaller by one dot than the sum of the number of dots 2 of a print head 1 and the largest number of dots of a character font. Thus a bit pattern is developed up to the final dot of a character font and stored in a buffer when one character font covers a twice print range for the head 1. Then each dot 2 of the head 1 is selectively driven based on the bit pattern of the buffer equivalent to the print range of the head 1. Thus the character font is printed up to its middle part, and the next print is carried out based on the bit pattern of the character font which is already developed. As a result, the slowdown of the printing speed due to a font developing job can be avoided.

Title: Storage device for strip
Inventor: MIYAMOTO TADANORI
IPC: B21C49/00
Filed: 1987-03-23
Abstract: PURPOSE:To equalize both right and left wire lope lengths and to prevent a deflector roll axis from slanting by winding a wire lope on a grooved wheel installed on the center line in the lateral direction of a loop car having a deflector roll and winding the lope form both right and left side ends of a winding drum symmetrically to the winding drum center. CONSTITUTION:Right and left wire lopes 1 are concurrently wound from both side ends when a winding drum 4 is rotated by actuation of a motor 5. In that time, the length of both right and left wire lopes 1 are automatically equalized by turning of a grooved wheel 13 even if the lope 1 is expanded. A combined force of both tension always acts in the direction parallel to the center line X. Therefore, a loop car 2 always moves on a rail 9 along the line X, so that the axis Y of a deflector roll 7a on the loop car 2 is kept in the orthogonal direction to the line center line X. Thus, meandering of a strip 8 in the lateral direction is prevented.
