Title: Phase locked loop circuit
Inventor: KASAI KENICHIRO
IPC: H03L7/10
Filed: 1990-01-23
Abstract: PURPOSE:To shorten the lock-in time for re-input of an input signal by inputting the detection result of the phase error between output signals of a selecting circuit and a voltage controlled oscillator to a loop filter and controlling the oscillation of the voltage controlled oscillator by this loop filter. CONSTITUTION:An input signal 4 at intervals of a time shorter than the time set by a signal input detecting circuit 10 is inputted again after being stopped. The signal input detecting circuit 10 detects the input of the signal, and the output of a selecting circuit 9 is switched to the input signal 4 by a switching signal 11. Consequently, the frequency is locked when phase comparison between the input signal 4 and an output signal 5 in a phase comparator 1 results in coincidence. When the clock frequency of a reference clock 8 is equalized to the frequency of the input signal 4, it is less necessary to synchronize the frequency and it is necessary to lock in the phase the time of re-inputting the input signal 4. Thus, the time required for lock-in is shortened.

Title: Optical anisotropy-measuring apparatus, optical anisotropy-measuring method, and manufacture for liquid crystal device using the optical anisotropy-measuring apparatus
Inventor: OSAKI YOSHINORI
IPC: G02F1/13
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To accurately measure optical anisotropy of a body to be detected, by restricting a shift of a measuring area due to the rotation of the body to be detected. SOLUTION: An incident luminous flux (parallel luminous flux) A projected from an He-Ne laser device 1 is linearly polarized by a polarizer 2 and brought into a sagittal lens 11a kept in tight contact with a liquid crystal cell 5. A center of curvature of this sagittal lens 11a agrees with an intersection of a rotational center of the liquid crystal cell 5 (on an axis of a rotary shaft 8) and a central axis of the incident luminous flux A, and therefore, the luminous flux entering the sagittal lens 11a passes the same point regardless of the rotation of the liquid crystal cell 5. Accordingly, optical anisotropy can be accurately measured at the same area even when the liquid crystal cell 5 is rotated.

Title: Switching power source
Inventor: NAKAYAMA TOSHIMITSU
IPC: H02M3/28
Filed: 1991-02-05
Abstract: PURPOSE:To reduce an input voltage at the time of an input current limiting to a predetermined value or less by varying an input current limiting value upon change of the input voltage, and setting the limiting value meeting the voltage. CONSTITUTION:An input current is converted to a voltage V2 via a resistor R1, and input together with an input voltage V1 to a multiplier 4. If an input voltage is a standard value constantly, an error amplifier 6 compares an output of the multiplier 4 with a first reference voltage of a reference voltage source 5. When the input current increases so that the output of the multiplier 4 exceeds the first reference voltage, a bias is applied to a voltage/pulse width modulator 7, a pulse width is narrowed, and an output voltage of a switching power source 1 is lowered. Since the multiplier 4 multiplies the voltage V2 proportional to the input current by the voltage V1, if the voltage V1 is higher than the standard value, an input current limiting value becomes low, while if the voltage V1 is lower, the limiting value becomes high. That is, an input power of the power source 1 becomes a predetermined value or less.
