Title: Remote supervisory and controlling system
Inventor: CHIBA YOSHIHIRO
IPC: H04Q9/00
Filed: 1983-06-22
Abstract: PURPOSE:To simplify the circuit of a remote supervisory and controlling system, in which data transmission and calls can be performed between the controlling station and plural controlled stations, by commonly using a signal source for a telephone calling signal and service interruption informing signal. CONSTITUTION:When a telephone call is made, a signal having a frequency f1 is sent out to a control station through a switch A9 and, when a service interruption is informed, another signal also having the frequency f1 is sent out to the control station through another switch A8. The frequency f1 is detected by a frequency disciminator B17 at the control station side and, since a data signal is transmitted or received with the data signal being conveyed by means of a carrier CD of a prescribed frequency f0, the carrier CD is detected at the demodulator B12 of the control station B. Since even the carrier CD is not sent out in the case of a service interruption, a logic section B18 discriminates a telephone call from information of a service interruption by using the condition as an index.

IPC: G02B6/42
Filed: 1977-09-13
Abstract: PURPOSE:To effect highly efficient excitation by adjusting the positions of the exciting end faces of a light source and an optical fiber such that the intensity of the light waves, which are reflected on the other end face other than the exciting end  face of the optical fiber, may become the maximum. CONSTITUTION:The light waves 6 emanating from a light source 4 pass through an optical brancher 11 so that they are excited by the exciting end face 2 of an optical fiber 1. The light waves 7 thus excited are reflected on the other end face 3 so that the reflected light 10 advances toward the exciting end face 2 until it  emanated therefrom. The reflected waves 10 are introduced into an optical detector  5 by an optical brancher 11. The position of the exciting end face 2 is adjusted by a  fine adjusting jig 9 in a manner to maximize the output of the detector 5 so as to attain a highly effecient excitation. According to the present invention, the position adjusting operation of the exciting end face 2 and the operation for measuring the output of the detector 5 are accomplished adjacent to each other without fail. Thus, it is convenient and possible to eliminate wireless or wired communication for the above information transmission.

IPC: H04B10/291
Filed: 1978-09-09
Abstract: PURPOSE:To realize a simple optical transmission branch line featuring an assured operation by driving the optical switch with part of the control signal transmitted to the optical fiber. CONSTITUTION:Both the communication signal and the control signal are transmitted into optical fiber 3, and the control signal is branched through branching filter 12 to be demodulated by demodulator 14 and via optical receiver 13. Thus optical switch perfect reflector plate 15 is put in and taken out by the demodulation signal of the control signal, and the communication signal is branched into optical fiber F1 or F2. In such way, the control signal is transmitted via the optical signal, thus eliminating the noise induction due to the electromagnetic induction as well as ensuring an assured operation. At the same time, the number of the rod lenses can be decreased to simplify the constitution.

Title: Solid-state relay
Inventor: NAGAOKA YUICHIRO
IPC: H03K17/78
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To reduce a turn-on time without accompanying increase in costs and power consumption by charging capacity between the gate and source of a transistor with electric charge of a capacitive element that is charged with load voltage and reducing a voltage build-up time between the gate and source. SOLUTION: When an optical signal is received, a photodiode array 2 generates current, a control circuit 4 receives it and becomes high impedance and the current charges capacity between the gate and source of an N channel enhancement type field-effect transistor 3. Since electric charge, that is charged in a capacitive element 7 when an optical signal is not received, also charges the capacity between the gate and source of the transistor 3 through a discharge current limit resistance 6, and NPN type transistor 5 and the controller 4, voltage build-up between the gate and source is accelerated. When the voltage between the gate and source exceeds threshold voltage, a part between output terminals 3a and 3b becomes a conductive state and current is caused to flow from a load power supply 16 to a load 15.

Title: Light transmission element, surface light source device and display device using the surface light source device
Inventor: SUGA YOSHINORI
IPC: G02F1/13357
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To obtain a light transmission element reduced at its thickness and weight, capable of preventing the generation of a warp or distortion on a light emitting surface, having high surface luminance, high light emission efficiency and simple structure and allowed to be easily produced by setting the extending surface of a light incident surface and a light exiting surface to a specified angle and arranging the reflection surface opposed to the light incident surface.

Incident light from the light source 12 is converted into a direction satisfying a total reflection condition in the element 11 by a reflection surface 33 formed on a face opposed to a light incident face 17, led into the inside of a light exiting part 32, and by repeating total reflection, the reflected light is allowed to arrive at light scattering dot 14 or the like without almost losing light energy and scattered to the direction of the light exiting face 10 to form a beam like a uniform face.  An angle formed by the extended face of the light incident surface and the light exiting surface is 0 to 70 deg., preferably 0 to 50 deg. and more preferably 0 to 30 deg..
