Filed: 1989-10-03
Abstract: PURPOSE:To make a resistance flat and small in size by connecting plural resistances made of a thin film or a thick film between many light emitting elements and the output terminal of a driving IC, irradiating the resistances with a laser beam so that the form of the resistances may be changed and adjusting the resistance value. CONSTITUTION:The resistance for limiting a current is vapor-deposited on the resistance mounting area 30 on a printed board 23 in a state where it is connected with many light emitting elements which form an LED array 21 and the output terminal of the driving IC 22.

Title: Display device for measuring instrument
Inventor: TSUDA KATSUHISA
IPC: G02F1/1335
Filed: 1991-10-07
Abstract: PURPOSE:To facilitate the change of a light source, certainly interrupt electrifica tion, and facilitate the visual confirmation of a display content at the time of changing the light source by installing a light source unit to the grooved light source receiving part of a back light and mutually connecting power source side and body side connectors to supply a driving power source. CONSTITUTION:A connecting part 70 is operated to move a casing 10 upward, and a light source side connector 86 is pulled out from a body side connector 64. Since these connectors have terminal lengths for conducting sequence connection, outputs of a light source tube 82 and a driving circuit 66 are interrupted after the input to a light source driving circuit 66 is cut, so that the generation of a high voltage according to the pulling can be prevented. When a liquid crystal panel 20 has positive display, the reflecting area of external light is extended to facilitate the visual confirmation of the display. An upper cap 12 is successively removed to pull the light source tube 82. When the light source tube 82 is pulled as it is forgotten to remove the connector 86, the connector is never removed as lock is worked thereon, and a cord part 84 is overly stretched to pull the light source pipe 82.

Title: Control circuit for test of transmission line
Inventor: NAKAMURA YUZO
IPC: H04B3/46
Filed: 1984-12-10
Abstract: PURPOSE:To test a transmission line only with a line for signal transmission without sending out a signal to the line all the time for maintaining a test state by providing a control circuit which allows signals to by-pass a signal regenerating circuit in a repeater. CONSTITUTION:A test start signal from a station is passed through a down circuit 10 and detected by a test start signal detecting circuit 1 to control the control circuit 2, thereby setting a switch 4, which is set at the side of the signal regenerating circuit 3 in the repeater to the side of a detour line 5. Consequently, the transmission line is considered as a couple of cables. A test end signal from the station is detected by a test end signal detecting circuit 6 to control a test end signal sending-back control circuit 7, thereby setting a switch 8 so that the test end signal is sent out to the side of an up circuit 11. A host repeater detects the test end signal from the low rank repeater by a test end signal detecting circuit 9 and the control circuit 2 is so controlled as to maintain the test state when the test end signal is detected or to control the switch 4 so that the test state is reset unless the test end signal is detected. The test state is thus reset successively from low rank repeaters.
