Title: Centering device of optical fiber cable
Inventor: TAKAHASHI HIDEO
IPC: G02B6/24
Filed: 1983-03-11
Abstract: PURPOSE:To remove cut-of-center and to attain the centering of cables easily even if the diameters of the cables are different by previously matching the centers of centering means obtained by arranging holding plates with notched parts properly. CONSTITUTION:The holding plates 5, 6 are arranged so that a gap formed by the notched parts 7, 8 is a regular square. A holding plate driving part 9 drives the holding plates 5, 6. Plural centering means are arranged and fixed on a fixing board 10 so that mutual centers are matched by an optical method. Consequently, the gaps of the notched parts 7, 8 are changed similarly. If a cable is inserted when the gaps are expanded and then the driving part 9 is operated so that the gaps are reduced, the cable is always guided into the center and held. Thus, the cables held by the plural centering means can be matched at their centers even if their finishing diameters are different.

Title: Driver condition sensing device
Inventor: KANEDA MASAYUKI
IPC: G01B11/00
Filed: 1993-02-03
Abstract: PURPOSE:To accurately sense stably the eventual speeling condition of a driver by catching the position of eyes certainly CONSTITUTION:The lightness difference in an iris part set on the digitized image data of a face and sensed within a window with assumption that an eye lies in this range is checked by Step S501 whether any change in the lightness exists in a certain period of time. If yes, the missensing judging flow counter is reset by Step S502, and sensing the sleeping condition is continued on the basis of the pattern of the change. When no change is generated for the first time, the window position is shifted by replacing the reference value selected at window setting by Step S505. If no cange lasts further, the threshold of the digitizing is corrected by Steps S506, S507, and the window is re-set with new image data. Thereby missensing of eye is corrected automatically.

Inventor: KONOSHIMA MAKIKO
IPC: H04N19/91
Filed: 1993-03-01
Abstract: PURPOSE:To improve picture quality and encoding efficiency by using a local decoded value from one camera to generate a code book of another camera. CONSTITUTION:An encoding processing part 1-1 performs vector quantization for multiple-eye stereoscopic image data F1 outputted from one camera by using a fixed code book 4-1 and then outputs the encoding process result information as training data to a local decoding part 2-1.

IPC: H03K17/60
Filed: 1982-03-16
Abstract: PURPOSE:To improve a crosstalk characteristic in case when a signal is cut off and also power consumption in that case, by using a field effect transistor in a wide band emitter-follower type switching circuit of or a switching circuit using a diode. CONSTITUTION:When a controlling transistor 5 is turned on by controlling a base current of the transistor 5 by the potential of a control terminal 6, a current flows to a resistance 9, and the gate-source voltage of a field effect transistor (FET) 15 is set to reverse bias voltage by a voltage drop generated in the resistance 9. Accordingly, the FET15 becomes a cut-off state, and the current flowing in the resistance 9 becomes a bias current of the emitter of a transistor (TR) 3 and the base of a TR4. As a result, emitter-follower circuits of 2 stages are operated, and a signal is outputted to an output terminal 2. When the TR5 is turned off from the control terminal 6, the FET15 attains to a conducting state, the potential of a connecting point 10 attains the same potential as that of an electric power source terminal 7, and the base-emitter potential of the TR3 and 4 is biased in the reverse direction. Also, the connecting point 10 is grounded in AC.

Title: Differential amplifier
Inventor: HIYAMA SATOSHI
IPC: H03F3/45
Filed: 1985-03-01
Abstract: PURPOSE:To decrease noise at an input terminal in the inside of an IC by controlling a current flowing to a resistor setting an input impedance in an emitter feedback type differential amplifier. CONSTITUTION:A base of a transistor (TR) Q7 having the same characteristic as that of a TR Q1 is connected to a base of a TR Q2 and the TR Q7 is biased by a constant current 14. Thus, the sum of the base currents of the TR Q7 and the TR Q2 flows to a resistor R3. It is required to make each potential (potential at a point A) of the TRs Q2, Q7 equal to a base potential (potential at a point B) of the TR Q1. Thus, in fixing a resistor R1, the resistor R3 is decreased. Thus, the output value of the constant current source 14 is selected properly and decreasing the resistor R3, then the noise at the input terminal in the inside of the IC is reduced.
