Title: Optical demultiplexer and multiplexer
Inventor: IEDA TOMOAKI
IPC: G02B6/28
Filed: 1985-12-20
Abstract: PURPOSE:To correct a shift in convergence position with wavelength with the tilt angle of the tip surface of an optical fiber array and the intervals of the optical fibers by slanting the tip of the optical fiber array of optical fibers which are arrayed by forming grooves in a flat plate. CONSTITUTION:The optical fiber array 24 of arrayed and fixed optical fibers 25a-25c is formed by putting the optical fibers 25a-25c between the flat plate 26 where grooves 28 are formed and a flat plate 7, and their tips are slanted. Light with wavelength lambda1 which is projected from the optical fiber 25a is incident on the optical fiber 26b and light with wavelength lambda2 is incident on the optical fiber 25c to obtain an optical demultiplexer function; and they travel through the opposite paths to obtain an optical multiplexer function. In this case, theta=tan<-1>(S'/d), where (d) is the interval between the optical fibers 25b and 25c, theta is the tilt angle of the tip of the optical fiber array, and S' is the difference between the distances of convergence positions of the light beams with the wavelengths lambda1 and lambda2 (lambda1<lambda2) from the end surface of a rod lens 1. Consequently, the shift in the convergence positions of the light beams with the wavelengths lambda1 and lambda2 is corrected.

Filed: 1994-10-31
Abstract: PURPOSE: To detect bar code at the same time when a data disk is rotated by setting and storing a detection level based on the output of respective photosensors in a state where a film is stopped. CONSTITUTION: When a film cartridge is loaded in a camera and the cover of the cartridge is closed, a CPU 1 is started and the output of the sensor 4 being the reflection type photosensor is detected. Then, the detected value is A/D-converted by an A/D converter in the CPU 1 and stored in a RAM. Similarly, the output of the sensor 5 is detected and the detected value is stored in the RAM through the A/D converter in the CPU 1. By the CPU 1, the criterion of a comparator for pulsizing an analog detection signal with respect to a voltage corresponding to a center based on the stored A/D converted value is decided and set by D/A conversion. Besides, the decision level is stored in a memory 7. By setting the decision level in a state where the data disk is stopped in such a way, the bar code of the data disk 7 can be precisely detected on and after it.

IPC: H04B7/26
Filed: 1993-10-25
Abstract: PURPOSE:To utilize a power supply of a slave set effectively and to prolong the service life of a power supply by varying the repetitive period of intermittent reception depending on a reception waiting time. CONSTITUTION:A slave set side CPU 2a-1 measures a reception standby time Tw from a point of time of end of talking. ON/OFF of a battery power supply is repeated at a predetermined repetitive period (t) for the time Tw to conduct intermittent reception. The period (t) is selected to be several hundreds msec. Then, whether or not the time Tw exceeds a predetermined time To is discriminated and when the time Tw is within the time To, the state is restored to the initial state again and the intermittent reception at the period (t) is implemented. When the time Tw exceeds the time To, the intermittent reception with a longer period than the usual period (t) is implemented. The repetitive period is selected to be about 2sec. Thus, the consumption of the battery power supply of a slave set 2 with limited capacity is suppressed.

Abstract: PURPOSE:To prevent bias currents from concentrating and flowing to the front edge sections of electrodes by forming trenches respectively parallel with the end sections of the electrodes and having specified depth near the end sections of the electrodes on a compound semiconductor. CONSTITUTION:Trenches 7 are shaped near the end sections of each electrode 3 and in specified depth to a compound semiconductor 2 in parallel with the end sections. Consequently, bias currents 6 are collected to the substrate 1 side once by the trenches 7 even when bias currents 6 concentrate and flow to a low resistance layer 5 by forming the trenches 7 to the compound semiconductor 2, and released toward the electrodes 3, thus largely making the uniformity of current density in the electrodes 3 better than conventional devices. It is preferable that the width of the trench 7 is thinned extremely. It is because the increase of resistance is reduced by collecting bias currents 6 to the substrate 1 side. The trench 7 is shaped by cutting the low resistance layer 5, and one third or half of the thickness of the compound semiconductor 2 is proper in order to improve the uniformity of current density in the electrode 3 in the depth of the trench 7.
