IPC: B62D11/08
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To eliminate nonconformity that a travelling device on the power transmission blocking side does not quickly return to a power transmission state and overruns as return of a piston is delayed because return oil passing a cylinder port from an oil chamber of a hydraulic cylinder is slowly discharged to an oil tank from a pump port after it passes a narrow oil passage in a directional control valve while receiving resistance by confluencing with unload oil from the pump port even when the directional control valve is returned to a neutral position after revolving a frame body to a desired position as before. SOLUTION: This device is furnished with hydraulic cylinders 12a, 12b having left and right pistons 14a, 14b to supply braking force by independently blocking power transmission to left and right traveling devices and a directional control valve 16 altetrnatively supply pressure oil to each of oil chambers 13a, 13b of the hydraulic cylinders, and it is constituted not to make an unload circuit of a pump port Pa at a neutral position N of the directional control valve confluent with a tank circuit to cylinder ports CL, CR of the hydraulic cylinders.

Abstract: PURPOSE:To simplify the constitution of a magnetic recording/reproducing device by reproducing a pilot signal whose frequency is changed in the prescribed repetition order from each track with two rotary heads, comparing the phases with each other between adjacent tracks to hold them and using this output to correct the variance of phase between tracks. CONSTITUTION:A head drum 2 of a magnetic recording/reproducing device which contains a magnetic tape 1 is controlled by a capstan motor 26. The video signals recorded on the tape 1 are reproduced by rotary heads 3a and 3b and applied to BPFs 12a, 12b, 30a and 30b via head amplifiers 11a and 11b. A pilot signal whose frequency is changed in the prescribed order is extracted from each track by BPFs 12a and 12b as well as 30a and 30b. The pilot signal is applied to phase comparators 13 and 31, and said heads compare the positions of signals extracted out of odd and even tracks. The outputs of circuits 13 and 31 are held by sample holding circuits 14 and 32 respectively and then applied to a timing signal generating circuit 19. Thus the position shift can be corrected between tracks.

IPC: B41J17/04
Filed: 1983-06-07
Abstract: PURPOSE:To record by efficient thermal transfer by using an ink sheet capable of being used plural times for thermal transfer, by automatically returning the ink sheet by an amount equal to the amount used for recording. CONSTITUTION:When recording is started, a one-way clutch 13 on the side of a take-up roll 7 is thrown in, and the ink sheet 1 starts to be taken up on the roll 7 without sagging under the function of a friction member 12.

When recording on one page is completed and the trailing end of a recording paper 2 is detected by a sensor 9, the controller 10 drives the motor 3 to rotate reversely in response to a detection output S. At this time, a one-way clutch 13 on the side of a supplying roll 6 is engaged. The controller 10 counts the number of steps by which the motor 3 is driven in reverse rotation, and stops driving when the counted value reaches the previously counted value, whereby the ink sheet 1 is returned by an amount equal to the amount by which the sheet 1 has been fed in recording.
