Title: Memory using method for deinterleave execution
Inventor: SONE TOSHIHIKO
IPC: G11B20/12
Filed: 1986-06-10
Abstract: PURPOSE:To simplify calculation of a recording address of data to shorten the deinterleave processing time by performing deinterleave simultaneously with data write to a memory. CONSTITUTION:In case that interleaved parallel data is written in the memory, the memory space is divided into eight packs correspondingly to delays of individual data and they are allowed to correspond to pack delays, and data is successively recorded on corresponding memory blocks. After one-pack components of data are recorded, the pack delay corresponding to each memory block is reduced by one and pack delay '0' is changed to 7. Recording of one pack in the memory and update of pack delays are repeated to always obtain deinterleaved data in the block of delay '0' after recording of one-pack components of data, thus shortening the deinterleave processing time.

IPC: H04B10/60
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To minimize group delay characteristic degradation within a prescribed frequency band and to provide prescribed group delay characteristics by optimizing the characteristic impedance of a transmission line in an increasing direction proportionally to the length of the transmission line for connecting plural high frequency circuits and the input/output matching characteristics of the high frequency circuits. SOLUTION: Optical signals are converted to electric signals in a photodetector 1 and signals low-noise-amplified in a preamplifier 2 are transmitted to a post-amplifier 4 through the transmission line 3, amplified to a prescribed output level and outputted. In this case, corresponding to the length of the transmission line 3 for connecting the preamplifier 2 and the post-amplifier 4 and the input/output matching characteristics of the post-amplifier 4, the characteristic impedance of the transmission line 3 is optimized (enlarged) within the range of not losing the characteristics and stability of the pre-amplifier 2 and the post-amplifier 4.  Thus, the influence of reflected waves passed through the transmission line 3 is reduced, the degradation of the group delay characteristics by the reflected waves is suppressed and a light receiver provided with the excellent group delay characteristics is obtained.

Title: Production of optical waveguide having reflection part
Inventor: KAGAMI MANABU
IPC: G02B6/13
Filed: 1994-05-23
Abstract: PURPOSE:To simplify the process for production by simultaneous formation of reflection parts and optical waveguides. CONSTITUTION:An underclad 3, an optical waveguide layer 11 and an etching mask are formed on a substrate 4. This mask is patterned and formed to the shape of the optical waveguides 1 and is formed with slits of a microwidth 15mum. The optical waveguides are separated by etching the optical waveguide layer after setting the speed ratio of chemical etching and physical etching at a desired value. The etching width in a transverse direction is determined by the speed of the chemical etching and the etching speed in a perpendicular direction is the sum of the chemical etching speed and the physical etching speed. The speed of the physical etching is variable with the slit width. The depth of the grooves of the reflection parts 2 and the angle of the reflection surfaces are, therefore, controllable. The simultaneous formation of the reflection parts 2 and the optical waveguides 1 is possible.

IPC: H03F1/42
Filed: 1983-07-25
Abstract: PURPOSE:To prevent baking of a base drive circuit by providing a temperature sensor detecting the temperature rise of an internal resistance between base and emitter of a transistor (TR) and disconnecting the base drive circuit of the TR when the detected temperature exceeds a prescribed value. CONSTITUTION:The temperature sensor 6 detecting the temperature rise of the internal resistance is provided between the base and emitter of a TR3. Since an output from the sensor 6 is given to a signal converter 7, the converter 7 forms a signal to interrupt the base of the TR3 when the output from the sensor 6 exceeds a setting value. Thus, the base drive circuit 1 receives a signal from the converter 7 so as to interrupt the base of the TR3. As a result, even if the TR3 is destroyed, the baking of the drive circuit is prevented by disconnecting the base drive circuit.
