Title: Optical boundary detector
Inventor: MATSUMOTO TAKAHIKO
IPC: G01B11/00
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of detection error even when the optical boundary to be detected is a circular arc by providing a comparator, etc., which output a difference between the output signals of photoelectric conversion elements at diagonal positions out of the respective positions corresponding to the vertexes of a square. SOLUTION: Comparators 2a and 2b output differences α and βbetween the output signals from two pairs of photoelectric conversion elements 1a and 1c and 1b and 1d which are placed diagonal to each other, among four positions corresponding to the vertexes of a square. A selector 3 selects one pair thereof whose difference between the output signals from the comparators 2a and 2b is larger than that of the other. Amplifiers 4a and 4b amplify the output signal of the selected pair so that it may be at the same level to the same amount of incident light. An amplifier 4c amplifies the output signal from a photoelectric conversion element 1e at a position equivalent to the center so as to make it to be at two-fold level in the same amount of incident light.  A computing device 5 subtracts the output of the amplifier 4c from a sum of outputs of the amplifiers 4a and 4b, and when the result becomes zero, it outputs a boundary detection signal G.

Title: Distortion compensating method in amplifier circuit
Inventor: SONE MASATO
IPC: H03F1/34
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To realize a circuit capable of effectively suppressing mutual modulating distortion without using a complicated circuit using an active element and a delay line. SOLUTION: This distortion compensating method allows a low frequency filter LPF1 to fetch the component of a frequency equivalent to the difference frequency of frequency components or a frequency interval, which should be amplified by an amplifier AMP, among various kinds of distortion components appearing in the output of the amplifier AMP, adjusts its phase and amplitude and then feeds back them to the input of the amplifier AMP. Since mutual demodulation distortion appearing in the output of the amplifier AMP at the time of executing feedback like this depends on a feedback quantity by a feedback loop, mutual demodulation distortion can be suppressed by properly fixing the adjusting quantity of an amplitude and a phase in an attenuator ATT and a phase shifter PS.

Title: Liquid crystal display device
Inventor: HARADA YOSHIHARU
IPC: G02F1/13
Filed: 1989-02-09
Abstract: PURPOSE:To decrease external light reflecting on the surface of a device and to improve the visibility of the display pattern by arranging a polarizing plate so as to be inclined with respect to a liquid crystal cell, and providing a light shielding plate preventing the injection of the external light proceeding toward a visual inspector after it reflects on the surface of the polarizing plate. CONSTITUTION:The polarizing plate 2 is arranged so as to be inclined with respect to the surface of the liquid crystal cell 1, and the light shielding plate is provided around the polarizing plate 2 to prevent the injection of the external light proceeding toward the visual inspector 7 after it reflects on the surface of the polarizing plate 2. Therefore, the reflecting light A on the surface of the polarizing plate 2 proceeds in the direction of the light shielding plate 4, and it is not made incident on the eyes of the visual inspector. The reflecting light B, which passed through the polarizing plate 2 and was reflected on the surface of the liquid crystal cell 1, passes through the polarizing plate 2 again and is made incident on the eyes of the visual inspector, but the incident light amount is very little because it reciprocatingly twice passes the polarizing plate 2 low in transmitting rate. The external light which proceeds toward the visual inspector after it reflects on the surface of the polarizing plate 2 is completely shielded by the light shielding plate 4. Thus, the reflecting light which made incident on the eyes of the visual inspector 7 is significantly decreased, and therefore, the visibility of the display pattern is largely improved.

Title: Power supply turn-on remote control system
Inventor: TARUSAWA KUNIAKI
IPC: G06F1/00
Filed: 1986-02-14
Abstract: PURPOSE:To turn on a power supply in a designated device out of devices connected to a cable on the basis of a multi-drop system by supervising presence of absence of a signal sent to the cable, and after detecting the signal sending, turning on the power supply. CONSTITUTION:When a signal is sent to the cable 1, a logic deciding circuit 2 converts the signal into a logical level of '1' or '0' and the logic level is sent to a latch circuit 3. After continuing '1' for a prescribed time, the latch circuit 3 is driven for the prescribed period and then sends '1' and the signal '1' is inputted to a NOR circuit 5 through a closed switch 4 when ON of a power supply is programmed by remote control. Since both the inputs of the NOR circuit 5 are turned from '0' and '0' to '1' and '1', the circuit 5 sends '0' to a repeater 6. When '0' is sent from the circuit 5 to the repeater 6, current flows from a power supply +E to actuate the repeater 6, so that a contact 8 is closed to turn on the power supply and a contact 7 is closed to send '1' to the NOR circuit 5. Consequently, the NOR circuit 5 sends '0' even if the latch circuit 3 outputs '0' after a fixed time, so that the repeater 6 continues the operation.
