Title: Optical fiber
Inventor: RAMAN KASHIYAPU
IPC: G02B6/44
Filed: 1995-02-22
Abstract: PURPOSE: To improve the temperature dependence of the transmission lag characteristic of an optical fiber by providing a jacket which reduces the temperature dependence of the transmission lag of the fiber, within a predetermined temperature range. CONSTITUTION: An optical fiber is constituted by burying a core 2 in a clad 3 and coating the clad 3 with a space coating 4. The coating 4 is further coated with another coating 5 which constitutes a jacket that is closely stuck to the optical fiber. The change in the transmission lag of the optical fiber caused by a temperature change in the fiber is caused by the changes in the length and refractive index of the fiber. The jacket acts against the transmission lag by causing physical distortion, namely, a refractive index change in the optical fiber by applying a stress when a transmission lag change occurs due to the temperature change. The jacket is selected, so that the transmission lag change caused in the optical fiber by the action of the jacket can substantially offset the transmission lag change caused by the temperature change of the optical fiber itself.

Title: Ultrasonic detector
Inventor: AZUMA NAOYA
IPC: G01N29/44
Filed: 1985-03-25
Abstract: PURPOSE:To detect a ultrasonic wave at high sensitivity irrespective of a subject to be detected by providing an azimuth detecting circuit detecting an azimuth where a subject and a human body exist and a circuit inhibiting an output when the output of the detecting circuit is beyond a preset azimuth range. CONSTITUTION:A period oscillator circuit 1 generates periodically a trigger signal, impresses a ultrasonic pulse signal as shown by a symbol (b) in figure to a vibrator 5 and emits said wave into air. When a received reflected pulse as shown by a symbol (d) after it is reflected by the subject is present in a detection gate which opens its gate as shown by a symbol (c) when the reflected pulse corresponds to the prescribed distance, an AND circuit 11 outputs a pulse as shown by a symbol (b). A time difference DELTAt between the reflected pulse shown by a symbol (e) and that shown by the symbol (d), both of which are received by a receiving sensor 6b, detects the azimuth. Only when it lies the preset azimuth range, the output of a flip-flop 12 as shown by a symbol (g) is outputted from an output circuit 13 in such a manner as a symbol (j) shows.

Title: Amplifier circuit
Inventor: HIROSE MASAKI
IPC: H03K19/0175
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To provide an amplifier circuit having a high gain, a high band and a high stable operation characteristic by alternately connecting a total feedback- type differential amplifier circuit, which can be made into a high band and level shift circuit which can arbitrarily set the DC level of an output signal. SOLUTION: This total feedback-type differential amplifier circuit 100 and a level shift differential amplifier circuit 200 are connected alternately. A capacitor (peaking capacitor) 42 is connected between the emitters of transistors 35 and 36. The capacitor 42 raises (peaking effect) a gain at high frequency and makes the band wide by suppressing the effect of the emitter negative feedback of emitter resistances 39 and 40, higher a frequency region becomes. A resistance (level shift resistance) 43 is connected between load resistances 37 and 38 and a high potential power terminal 5. Since a constant voltage drop can be obtained in the resistance 43, the value of the voltage drop is set appropriately. Thus, it can be set to a DC level, where the input transistor of the total feedback differential amplifier circuit 100 is not saturated.

Namely, the capacitor is formed in the outer surface peripheral part of the tele-panel 1 sandwiching the AR film 3, this is connected to a reinforcing band 5, and this band is then connected to grounded exterior graphite 10. Thus, a part of the AR film 3 is eliminated so as to eliminate the necessity of complex work such as electrode disposing, and an electrode forming process is simplified. Thus, electric charging of the front outer surface is prevented, reliability is improved and low-cost production is realized.
