Title: Read signal circuit for optical disk storage device
IPC: G11B20/10
Filed: 1992-03-24
Abstract: PURPOSE:To prevent the occurrence of an error by converting a detective signal from an optical disk to respective read signals with respective AGC circuits for preformat and data, and interrupting the operation of the AGC circuit for data for a suitable time whenever the preformat is detected. CONSTITUTION:By an optical senser 3f in a head 3, a detective signal DS is obtained which detects preformat(PF) and the data of a sector from the optical disk 1 using a phase changing type recording medium 1a. The signal DS is applied to AGC circuits 20 and 50 for the PF and the data, and the signal is converted to the read signal Sp of the PF by the circuit 20 and converted to the read signal Sd of the data by the circuit 50 respectively. When the PF is detected by the read circuit 30 receiving the signal Sp, the operation of the circuit 50 is interrupted and the operation is restarted when a time suited to the PF lapses thereafter. Thus, the read signal of an analog waveform is made from the detective signal from the common senser 3f accurately and the occurrence of a read error is prevented.

Title: Charged-particle beam device
Inventor: ASARI TOSHIHIRO
IPC: H01L21/30
Filed: 1988-03-18
Abstract: PURPOSE:To prevent the formation of a discontinuous pattern even when a positional specified signal for thinned-out scanning is transmitted over a DA converter by summing one-step output value from the DA converter and the peak level of a saw-tooth-wave signal, adding an output from the DA converter and an output from a saw-tooth-wave generating signal circuit and transmitting an added value over a deflecting system for controlling the position of beams. CONSTITUTION:A step control signal generating circuit 9 respectively transmits control signals, where the peak level of a saw-tooth-wave signal is equalized to one-step output value from a DA converter 1, over a saw-tooth-wave signal generating circuit 7 according to a command from a digital controller 5. Consequently, the saw-tooth-wave signal is generated from the saw-tooth-wave signal generating circuit. Since the saw-tooth-wave signal and an analog positional signal from the DA converter 6 are added in an adding circuit 10, a linear positional signal is sent to a deflecting system 3. Since the position of ion beams is controlled on a material by the deflecting system 3, ion beams gradually scan on the material without clearance. Accordingly, no discontinuous pattern is generated, thus drawing a continuous beltlike pattern.

Filed: 1989-03-16
Abstract: PURPOSE:To reduce the lock time of an AFC loop without increasing a loop gain of the AFC loop by stopping a frequency division of a frequency divider in response to the detection output of a mis-lock detection circuit, starting the frequency division again in response to an input signal arrived after the stop and locking the AFC loop forcibly. CONSTITUTION:When a mis-lock detection circuit 20 detects a large deviation of a phase between an output signal of frequency dividers 10-13 frequency- dividing an oscillated output signal of a voltage controlled oscillator(VCO) 9 and an external horizontal synchronizing signal, after a prescribed period from the detection, the count of the frequency dividers 10-13 is once stopped at a count when the AFC loop is locked. Moreover, the horizontal synchronizing signal is counted in response to the detection and the frequency division of the frequency dividers 10-13 is again started in response to the arrival of the horizontal synchronizing signal after a prescribed count to apply phase locking of the AFC loop forcibly. Thus, the lock time of the AFC circuit is shortened without increasing the loop gain of the AFC circuit.

Filed: 1979-05-28
Abstract: PURPOSE:To enable the stable continuous casting of undeoxidized steel and reduce the production of flaws by positioning a parting member in the central part of the mold and giving electromagnetic flow to the freezing boundary in the slab mold. CONSTITUTION:Linear motors 3 are installed respectively along both long sides 2 of a slab mold 1. These are so arranged that the thrusts thereof are given in mutually different directions 4, 4', whereby continuous film-formed electromagnetic flow 5 is given to the freezing boundary. At this time, a partition member 6 parallel to the long sides 2 is positioned in the central part of the mold to form a guide path 7 between the partition member 6 and long sides 2. Thereby, directivity is given to the flow so that the flows do not affect upon each other and the flows are surely guided, thus the smooth electromagnetic flow is formed at the freezing interface in the slab mold. In the length of this partition member 6 is about 1/3 the mold width, it satisfied both functions of separation and guide.
