Title: Tracking controller
Inventor: KIMOTO KIYOSHI
IPC: G11B7/09
Filed: 1985-02-04
Abstract: PURPOSE:To obtain a tracking error signal having always a constant sensitivity by normalizing the tracking error signal given by a difference between amplitude detecting signals available from detecting two envelops of subbeams by means of an envelop detecting signal from a main beam or the addition signal of the from two subbeams. CONSTITUTION:The tracking error signal detected by an operational amplifier 11 is inputted to the numerator input terminal A of a divider 17, and simultaneously the amplitude detecting signal of the main beam from a rectifying circuit 16b is inputted to the denominator input terminal B of a divider 18. The tracking error signal is splitted by the amplitude detecting signal of the main beam to normalize the tracking error signal. Thus linearity can be obtained in a wide range before and after the moment when the main beam can match to a track and the level of the signal comes to zero, and the detecting sensitivity of the tracking error approximates to a constant value. Even if a servo circuit is turned on immediately after jumping the track and a transient response can be obtained, the set time necessary for matching the main beam to the track will not vary, and moreover the time required for jumping the track can be shortened.

Filed: 1987-01-30
Abstract: PURPOSE:To enhance a printing quality, by a method wherein, a stand-by time is set with a pin protruded less than a printing stroke prior to the start of printing. CONSTITUTION:By traveling a printer 1 on a paper 3, an encoder 5 generates a signal due to the rotation of a roller 4. This signal is applied to a CPU 16 as a printing position signal through a timing generator 21. Then, a pin 9 is protruded to a position not to reach the paper 3. After that, a drive signal to the pin 9 of a printing head 6 is released, whereby the pin 9 is returned rearward from a position shown by Fig. A and the peripheral surface, and a tip end surface of the pin 9 is supplied with an ink 24 from a core 12. By driving the pin 9 through a head drive circuit 22, the pin 9 keeps abutting against the paper 3 to transfer the ink 24 to the paper 3 and stick it thereto. Opening of all the drive signals to the pin 9 results in the pin 9 being excessively moved rearward, and the peripheral surface and tip end surface of the pin 9 are supplied with the ink 24 from the core 12. Thereafter, reset of a timer 18 results in the pin 9 being restored to a position in Fig. D. In this manner, the ink is prevented from drying at the start of printing, which results in a good-quality printing.

IPC: B21B3/00
Filed: 1989-01-31
Abstract: PURPOSE:To produce the extremely thin cold rolled sheet of a high-strength titanium alloy which has excellent dimensional accuracy and is thin in thickness by applying tension to a titanium alloy sheet via leader coils, passing and rolling the sheet and subjecting the sheet to cold rolling at a specific total cold draft. CONSTITUTION:The pure titanium sheets TR35C for the leader are butted against the front and rear parts of the titanium alloy sheet A and are TIG- welded W to coil the sheet. The leader coils are respectively wound on tension reels provided on the front and rear surfaces of a cold rolling mill and the tension is applied via the leader coils to the titanium A, then the sheet is passed and rolled. The titanium alloy has poor plastic workability and is liable to generate edge cracks at the time of the cold rolling and, therefore, the total cold draft is limited to <=40% in the cold rolling. The treatment to restore the cold rollability is executed after the cold rolling. As a result, the thin cold rolled sheet of the high-strength titanium alloy which has beautiful surfaces and the excellent dimensional accuracy and is thin in thickness is efficiently produced.
