Title: Light emitting apparatus
Inventor: OKONOGI TATSUYA
IPC: F21V19/00
Filed: 1995-04-10
Abstract: PURPOSE: To realize a matrix light emitting apparatus with high contrast. CONSTITUTION: LEDs 1 are arranged in a matrix in a substrate 2 coated with a reflection preventive resin 3 and covered with transparent resin 4 having dome-like projected parts. Respective projected parts are partitioned by light shielding walls 6 with the minimum height necessary to shield light-rays emitted mutually neighboring light sources. Consequently, even in the case where outside light-rays enter the light emitting apparatus, the light-rays are hardly reflected and the light-rays from neighboring light sources hardly enter the neighboring LEDs, so that the contrast between turned-on LEDs and turned-off LEDs can be heightened. Moreover, the light shielding walls 6 do not need to be made higher than the projected resin 4, so that visible angle can be widened.  As for the projected parts 4, the more the distance of the tip parts and the LEDs 1 differs from the radius of the projected parts, the more light-rays are converged and on the other hand the more the distance becomes close to the radius, the more light-rays are dispersed. In this way, whether great importance is attached to high brightness or to wire visible angle becomes selective.

Title: Earth leakage circuit breaker
Inventor: HASHIMOTO TAKASHI
IPC: H02H3/33
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To perform break operation in a specified time in response to the magnitude of an earth leakage current, and at the same time to prevent unnecessary operation in a grounding current due to a lightning surge. SOLUTION: In an earth leakage circuit, output with a specific value or large of an amplification circuit 6 for amplifying the output of a zero-phase current transformer 3 is changed into pulse by a first comparator 7, a capacitor 8b of an integration circuit 8 is charged for the amount of time of the pulse width, and a break signal γis outputted for operating a tripping coil 11 when the charge voltage exceeds a threshold of a second comparator. In this case, by a current mirror current generation circuit 13 being inserted into the feedback circuit of the amplification circuit 6, the capacitor 8b is discharged by current with the same value as that of a feedback current being proportional to the current flowing in a ZCT 3. When an earth leakage current flows, break operation is made at a specific time.  On the other hand, when a grounding current due to a lightning surge flows, the charge voltage of the capacitor 8b does not exceed the threshold of the second comparator 9, thus preventing the break operation.

Title: Bypass route changeover system and switch back system
Inventor: KAWAHARA HIROTO
IPC: H04L45/24
Filed: 1992-04-06
Abstract: PURPOSE:To change over routes without error by devising the system such that a node unable to be in direct relay contact with a relevant node due to the occurrence of a fault collects node information of sets of nodes consisting of entire start nodes using the relevant node as a passing node to a destination and of the relevant node. CONSTITUTION:Upon the detection of a route fault to a destination node D, a node A sends a route re-configuration start message to nodes A-C, E, K of D-A fragment to collect information of each node. Moreover, the node A receives reports link object nodes being adjacent nodes of the nodes of the D-A fragment and having an output path to the node D and generates a list. The node A selects a node L from the list to select a new route. When the fault is restored, a node M invites switch-back to the node A, node information of the D-A fragment is collected and a regular outgoing link is selected after the confirmation of no disadvantage. Thus, a bypass and a regular route are selected without error.

Title: Line condition discriminating system
Inventor: YAMAKAWA TAKUYA
IPC: H04B10/038
Filed: 1987-04-06
Abstract: PURPOSE:To easily discriminate a line condition to an LAN system, etc., without fail by discriminating the line condition based on only the condition of a light signal when an optical fiber is used as a data transmission path. CONSTITUTION:When a trouble such as disconnection occurs at a light transmission system including an optical fiber, a light signal is never inputted to a photodetector 1, therefore, the output of an integrated circuit 4 is small as it is and the output signal of a voltage comparator 5 is a low level as it is. Consequently, an output signal Sig from a re-trigger type one-shot multi-vibrator 7 is held in the condition of the low level and an output signal CD from a voltage comparator 6 is also a low level as it is. When the trouble such as the disconnection never occurs at a light transmission system, the light of the constant level or the optical pulse, in which a level changes alternately between a low level and a high level, is guided through a light transmission system to the photodetector 1. Thus, based on whether or not an output signal Sig is a high level, it can be discriminated whether or not a data transmission is executed.
