Title: Pickup head in optical information processor
Inventor: YAMASHITA MAKI
IPC: G11B7/135
Filed: 1986-01-28
Abstract: PURPOSE:To improve S/N and responsiveness by constituting a light receiving system with a condensing means which condenses reflected light and a light receiving part which receives the light condensed by the condensing means. CONSTITUTION:The light emitted from a lens 2 passes a compensating plate 10 and goes toward an optical disk 20 and reaches pits 24 through a substrate 21 of the optical disk 20. The light reflected on pits 24 passes the substrate 21 and the compensating plate 10 and is made incident on a lens 3 on a substrate 1 and is condensed and is received by a light receiving part 3. Aberrations due to the projected light and the reflected light based on the difference in refractive index between air and the substrate 21 are almost solved. The reflected light from the optical disk 20 is condensed by the lens 3, and the condensed light is received by the light receiving part 4. Thus, one or plural photodetectors constituting the light receiving part 4 are made small in size to improve the S/N and responsiveness of a light reception signal.

Title: Pulse laser
Inventor: FUJIMORI YASUTOMO
IPC: H01S3/101
Filed: 1986-01-27
Abstract: PURPOSE:To stabilize a pulse laser in a simple and compact structure even if the number of laser beams to be combined is many and the pulse repetition is large by emitting a plurality of pulse laser beams toward a mirror of a rotatably driven polygonal mirror, and controlling the timing to emitting a light at the timing coincident on an optical axis with the same pulse laser beam reflected by the mirror. CONSTITUTION:A pulse laser beam 17 emitted from a first laser oscillator 15 is propagated through a reflecting mirror 13 while being controlled by a controller 20, incident to a mirror 12 of a polygonal mirror 11, and reflected toward an optical axis L. Then, after 1/2f hour, a second laser oscillator 16 is oscillated. A pulse laser beam 18 emitted from the oscillator 16 is propagated through a reflecting mirror 14 to be incident to the mirror 12. Since the mirror 12 is moved by the rotation of the mirror 11 at this time, it is similarly reflected in the optical axis L. Thus, the laser beams 17, 18 are similarly reflected in the axis L to be combined.

Title: Data compression method
Inventor: JIERAARU BATAIYU
IPC: H03M7/30
Filed: 1991-01-16
Abstract: PURPOSE: To adaptively achieve algorithm without the need of the statistical knowledge of a message source to be code compared by indicating the symbols of a signal source by the procedure of routing by a binary method from the one called as a root to the terminating end of a tree called as a leaf. CONSTITUTION: The symbols of the signal source are indicated by the procedure of routing to follow by the tree by the binary method from N0 called as the root until the optional one at the end of the tree called as the leaf. The respective leaves are related to each symbol of the alphabets of the signal source. For instance, the tree by the binary method for the four signal sources for which primary symbols are noted as a1 , a2 , a3 and a4 is indicated. The instructions of 'take a left branch' and 'take a right branch' is respectively related to a binary element (b)='0' and the binary element (b)='1'. Further, a tree expression is converted by merging the leaf to the root and the symbol display of the signal sources a1 -a4 is performed by the respective branches to the root N0 . Thus, the algorithm is adaptively achieved.

Title: Optical semiconductor device
Inventor: AZUMA TOSHIO
IPC: H01S5/00
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To both ensure a low threshold characteristic and no polarization dependency of a laser transceiver by inclining the direction of a resonator axially, and intersecting an inclination direction of a laser oscillator part serving also as an optical detctor part and an inclination direction of the optical detector part adjacent to the laser oscillator part each other. SOLUTION: This semiconductor device is divided into two regions in the direction of a resonator, i.e., a laser oscillator part A serving also as an optical detector part and an optical detector part B. Since there are opposite an inclination surface 1A of the laser oscillator part A serving also as the optical detector part and an inclination surface 1B of the optical detector part B, the laser oscillator part A serving also as the optical detector part and the optical detector part B intersect each other at their interface. Since an optical waveguide including a quantum well active layer is formed on a portion laminated on the inclination surfaces 1A and 1B, a TE polarization direction in the one region corresponds to a TM polarization direction in the other region.

Filed: 1983-02-01
Abstract: PURPOSE:To input a required command easily and accurately by retrieving and presenting the M number of kinds of the command from N number of kinds of the command with hand-written information and selecting and inputting an object command out of them. CONSTITUTION:When the hand-written information is inputted in a hand-written information input part 1, a retrieval control part 3 matches an inputted hand- written pattern and templates, which are stored in a template pattern storage part 3-1, to each other in a matching part 3-2. In a command selecting part 3-3, a command name corresponding to a matched template is retrieved from a command group stored in a command storage part 2. This retrieved command is displayed on a command display part 4 through a control part 3-4. The operator selects one of the command displayed on the display part 4 and inputs a number corresponding to this command from a command input part 5 to make the execution of this command possible. Thus, the operator can input a desired command without remembering a command name.

Title: Manufacture of semiconductor device; ecr cvd apparatus used for it
Inventor: SATO JUNICHI
IPC: H01L21/316
Filed: 1990-01-24
Abstract: PURPOSE:To make a throughput high by a method wherein, successively to a bias ECR CVD operation used to fill an insulating film, a leveling etching operation of an insulating film outside a trench is executed by an RIE method. CONSTITUTION:Trenches 2, 2 formed in surface parts of a semiconductor substrate 1 in which a pad layer 7 composed of SiO2 and an etching-stop layer 6 composed of polycrystalline silicon have been provided on the surface are filled with an insulating film 3 composed of SiO2 by a bias ECR CVD operation. Then, without exposing the substrate 1 to the air, a leveling etching operation of an insulating film 3a outside the trenches is executed in an RIE chamber by an RIE method. When the leveling etching operation is executed by the RIE method in this manner, the utilization efficiency of a source gas is high as compared with a case where the leveling etching operation is executed by the bias ECR CVD operation. Since a plasma can be generated near the surface of the semiconductor substrate 1, the energy of an etchant can be made high. Consequently, an etching rate can be made high.

Title: Fft spectrum analyzer
Inventor: ARATA HIROO
IPC: G01R23/16
Filed: 1991-02-06
Abstract: PURPOSE:To improve the spectrum analyzing sensitivity of an FFT spectrum analyzer by performing addition or subtraction on signals obtained by multiplying one parts of input signals divided into two parts by a window function and signals obtained by multiplying the other part of the input signals by a Hilbert-transformed window function after the other part of the input signals are Hilbert-transformed. CONSTITUTION:A halving device 2 divides inputs signals into two parts and another halving device 11 divides window function signals from a window function generator 9 into two parts. A multiplier 4 multiplies one part of the input signals divided into two parts by means of the device 2 by the window function signals. A Hilbert transformer 7 performs Hilbert transformation on the other part of the input signals. Another Hilbert transformer 14 performs Hilbert transformation on the window function signals. A multiplier 16 multiplies signals from the transformer 7 by the Hilbert-transformed window function signals. An adder 18 adds signals from the multipliers 4 and 16 to each other. Even when the signals from the multipliers 4 and 16 are subject to subtraction, substantially the same acting effect can be obtained.
