Title: Light emitting diode display device
Inventor: MAIKERU SHIMON
IPC: H01L33/00
Filed: 1989-08-24
Abstract: PURPOSE: To improve the efficiency and service life of a light emitting diode(LED) by enabling switching between an on-position, where an optical pulse is outputted to each associated LED at the optical device of N×M rectangular arrays, and an off-position not to output any optical pulse to each associated LED. CONSTITUTION: Optical devices 1-8 are provided with one or a plurality of LED and each LED is driven so as to output a string of optical pulses separated at the intervals of luminosity '0'. Since the temperature of LED cathode is decreased during the respective intervals of zero luminosity, the average temperature over the operating cycles of respective LED gets lower than the case of having zero luminosity intervals outputted for shorter duration time. Since a driving circuit has a finite non-zero RC constant and has capacitors C1 -C8 serially connected with the LED, the long duration time having the zero luminosity intervals between light emitting pulses. Each driving circuit is provided with switches T1 -T8 for changing over the circuit between ON mode and OFF mode. The respective switches are controlled by continuous digital signals L1 -L8 outputted from an interface device.  Thus, the efficiency and service life of each LED are improved.

Title: Infrared ray detecting element
Inventor: MORI NORIHISA
IPC: G01J5/02
Filed: 1992-07-23
Abstract: PURPOSE:To obtain an inexpensive downsized infrared ray detecting element having high sensitivity by arranging a pair of conductive parts oppositely, While spacing apart from each other, on a semiconductor fiber thereby forming a hybrid fiber. CONSTITUTION:A pair of conductive parts 2a, 2b are arranged, while spacing apart from each other, on a semiconductor fiber 1 having electric resistance variable with temperature thus forming a hybrid fiber 3. The conductive parts 2a, 2b are composed of good conductors having resistance close to zero and the resistance R of infrared ray detecting element is determined by the gap (d) between the pair of conductive parts 2a, 2b according to a formula; R = rhod/s. represents resistivity of the fiber 1 and even when the resistivity rho is set high in order to enhance sensitivity of infrared ray detecting element, resistance R can be decreased by decreasing the gap (d). Since the resistance R can be controlled without varying the length and the cross-sectional area (s) of the fiber 1, a fiber 1 having high resistivity can be used with low resistance without imposing negative effect on the thermal characteristics of the fiber 1. Furthermore, number of fibers 1 to be arranged in parallel can be decreased because of low resistance.

IPC: H04L5/22
Filed: 1990-08-16
Abstract: PURPOSE:To improve the transmission efficiency of a communication line by allowing a peripheral station to reply its operating state when a central processing station makes a transmission request to the peripheral station. CONSTITUTION:When a prescribed time T elapses while a central communication equipment 3 does not receive a message from communication equipments 5a-5h, that is, when a communication line W is idle, the equipment 3 sends a message requesting backup transmission to the equipments 5a-5h and when the backup transmission request comes to the equipments 5a-5h, the equipments 5a-5h make backup transmission. Thus, the transmission efficiency of the network is improved. Furthermore, when the arrival of a call of the usual transmission from the equipments 5a-5h takes place one after another in the equipment 3, no backup transmission is requested and since the backup transmission is requested when the message reception is not caused for a prescribed time T, the successive backup transmission in addition to the usual transmission is not reached from the equipments 5a-5h.
