Title: Transistor drive circuit
Inventor: OKATSUCHI CHIHIRO
IPC: H03K17/04
Filed: 1978-03-17
Abstract: PURPOSE:To obtain economical great current base drive circuit, by connecting the transformer and the rectifying circuit to the base and emitter circuit of the transistor Tr in opposite direction so that no current flows in the rectifying circuit during the base drive of Tr. CONSTITUTION:The output VOSC of the high frequency oscillator 1 oscillates continuous rectangular waves, and when the signal SIG controlling Tr 7 at time t0 is turned on, a signal is fed to the base of Tr 7 with Tr 3, 4, transformer 10, and rectifier 11. When the signal SIG is 0 at time t1, the signal VOFF is produced from the one shot generator 13 and flows the current of -IB in opposite direction to the base of Tr 7 via Tr 14, transformer 17, and rectifier 18. During the period at time t0 to t1, the number of rectifiers is selected so that the voltage drop of the rectifiers 18 is greater than the voltage between the base and emitter of Tr 7 to avoid the current from being flowed to the rectifier. Next, at time t2 to t3, the carrier storage of Tr 7 is discharged and -IB is decreased. Thus, the turn off time of Tr 7 is reduced, resulting in obtaining economical great current base drive circuit.

Abstract: PURPOSE:To enlarge the amount of information by providing a rotary cylinder, around which a magnetic tape is wound at more than 180 deg., to be rotated by N/2 for each field of a color video and prolonging the length of a recording track rather than the 1/2 peripheral length of the cylinder. CONSTITUTION:Three magnetic heads 17, 18 and 19 are close arranged on a rotary cylinder 15 to be rotated in a direction 16, and three magnetic heads 20, 21 and 22 are close arranged. The magnetic tape is wound around the cylinder 15 at more than 180 deg. and the three heads always get contact with the tape at least. The recording length of the video signal recording track is shorter than a length corresponding to a period for the magnetic head to be rotated at 180 deg. on the cylinder, namely, becomes about 165 deg.. The length of the sound signal recording track is corresponding to a period for the magnetic head to be rotated about at 15 deg. on the cylinder. Thus, since 6 magnetic heads are arranged on the cylinder 15 so that three magnetic heads can be respectively close to the rotational center, the vertical resolution of a reproducing picture can be improved at the time of special reproducing.

Filed: 1987-02-13
Abstract: PURPOSE:To attain segment extraction without distinction of segment kinds by means of a device constitution of a comparatively small scale by extracting a space between back picture elements on both ends among the back picture elements brought into contact with a white run block provided with a specified condition as a segment. CONSTITUTION:A CPU 12 sequentially accesses to picture memories 10 and detects white runs of a prescribed length or above. The CPU obtains the number of the back picture elements (black contact quantity) brought into contact with the up-and-down sides of the white runs, and extracts the white runs having black contact quantity of the prescribed value or above as effective white runs and extracts the white run block consisting of a crowd of the effective white runs which satisfy a prescribed link condition, to obtain the ratio of the total value of black contact quantity of respective white runs among the white run block to the width of the white run block. The space between the black picture elements on both ends among the black picture elements brought into contact with the white run block whose ratio is larger than the prescribed value is extracted. Since the extraction processing is easy, it can be executed with the comparatively simple device constitution, and the segments brought into contact with various segments and a character string can be extracted.

Abstract: PROBLEM TO BE SOLVED: To enhance the rigidity of a suspension bushing in the direction orthogonal to the axis thereof, and enhance the durability of a vibration isolating rubber member. SOLUTION: An inner cylinder having a bulged part 11 in the axially center part thereof, is coaxially set in an outer cylinder 2 having a large diameter part 21 with a constant diameter and opposite side parts 22, 23 with diameters which are decreased toward opposite ends.
