Title: Phase synchronization circuit
Inventor: KONDOU MASAO
IPC: H04L25/497
Filed: 1994-03-18
Abstract: PURPOSE:To reduce the error of a VCO clock due to asymmetry in a waveform peculiar to an MR head by detecting offset amt. of the MR head from a gap pattern and subtracting it from amplitude value of a data pattern. CONSTITUTION:Binary discrimination is performed by a binary/ternary discriminator 14 in a gap pattern area provided in front of a data pattern area, and a phase error is calculated by a phase comparator 15 in accordance with a binary discrimination value and the amplitude value to control a VCO 16. A measuring area is detected by an error detecting circuit 17 from a binary/ternary discriminating changeover signal and a data read-out signal which becomes a high level from the lead of the data pattern, and the when the discriminating value X(n) is '0', an offset error value DELTAE is calculated from the amplitude value Y(n), and is sent to a subtractor 18. The amplitude value Y(n) with deduction of the error value DELTAE is inputted to the phase comparator 15, where a phase error is calculated, and the VCO 16 is controlled by this phase error.

Filed: 1985-04-10
Abstract: PURPOSE:To prevent a current from leaking by forming a thick oxide film for separating between cells at the center of the bottom of a trench on a high density substrate, thereby eliminating a punch through in the deep trench portion. CONSTITUTION:A trench is formed by etching in the depth deeper than the thickness in a P-type epitaxial layer 2. In other words, the trench is formed in the depth deeper than the upper surface of a P-type Si substrate 1. A thick oxide film 3 is formed as a thick insulating film in the bottom of the trench so as to be slightly higher than the upper surface of the substrate 1, the cells are separated at A-A' line into the thick film 3 and the substrate 1 to separate between the cells. Thus, the leakage of the current due to the punch through in the portion deeper than the trench which was a disadvantage for a trench capacitor can be prevented.

Abstract: PURPOSE:To prevent malfunction due to simultaneous change in an output buffer by providing a 1st stage logic gate, the next stage logic gate and a one-shot pulse generating circuit supplying a lock signal on an input of the next stage logic gate while being triggered by an output of the next stage logic gate. CONSTITUTION:The titled circuit consists of the 1st stage 2-input NOR gate 3, the next stage 2-input NOR gate 4 and the one-shot pulse generating circuit 5 receiving the output of the gate 4 as the input, generating a high level pulse signal at the trailing of an output signal 4 and whose output is given to the other input of the gate 4. When an internal chip select signal 2 and an external input signal 1 go to a low level, the output of the NOR gate 4 reaches a low level. In this case, the circuit 5 generates a high level pulse signal. Moreover, the output buffer 6 generates the data signal by the output signal of the gate 4. Even when the level of the input signal changes based on the fluctuation of a ground line or a power line 7, since the output of the circuit 5 keeps a high level, the output of the gate 4 is unchanged.

Abstract: PURPOSE:To facilitate focus detection and automatic focus adjustment for a main subject by limiting a defocusing quantity to be detected and a lens driving quantity when the focus detection is performed in a relatively narrow focus detection area and then in a wide focus detection area. CONSTITUTION:This automatic focus adjusting device is provided with a selecting means 505 which selects a 1st or 2nd focus detecting means 503 or 504, a driving control means 506 which controls the driving quantity of a driving means according to the defocusing quantity of the focus detecting means, and a limiting means 507 which limits the focus-detectable defocusing quantity or lens driving quantity when the selecting means 505 selects the 2nd focus detecting means 504. When the selection is changed from the 1st focus detecting means 503 to the 2nd focus detecting means 504, the defocusing quantity and lens driving quantity are limited. Consequently, the main object is caught in the 2nd wide detection area and then even if an undesired object is caught in the widened focus detection area, the main object can easily be focused without being affected by the focus detection result.

Title: Revolution speed detecting device in taking-up device
Inventor: KOMORI TOSHIYUKI
IPC: G01P3/48
Filed: 1988-03-31
Abstract: PURPOSE:To correctly detect the number of revolution of a driven roller and obtain a uniform taking-up quantity of a strip-shaped material by installing a target element which integrally revolves with a driven roller, detecting element for detecting the pass, and a revolution absorbing means for holding the detection element at an immovable position. CONSTITUTION:When a drive roller 2 revolves and a driven roller 1 is revolved through a strip-shaped member 3, also a basic body 5 integrally revolves. While, a revolution absorbing member 7 is slided through a bearing 17, and since a detection element 8 is installed through an installation metal fitting 23 and a holder 24, a connection part 22 does not revolve in the downwardly suspended state because of the weight of the detection element 8. Therefore, even if the basic body 5 revolves, the detection element 8 is kept in a standstill state always at an immovable position. Therefore, a target element 6 crosses the front surface of the detection element 8 through the revolution of the basic body 5, and signals are obtained periodically from the detecting element 8. The signal cycle becomes equal to the revolution speed of a roller 1, since the basic body 5 and the roller 1 revolve integrally, and the revolution speed can be detected from the frequency.
