Title: Semiconductor waveguide type polarization control element
Inventor: KOMATSU YOSHIRO
IPC: G02B6/12
Filed: 1990-08-13
Abstract: PURPOSE:To reduce the size of the element by specifying the element length about lengths to a TE mode and a TM mode which are required for the complete movement of waveguide light power from one of two close three- dimensional optical waveguides to the other optical waveguide. CONSTITUTION:On a (100) azimuth semiconductor substrate, a 1st semiconductor clad layer, a semiconductor waveguide layer, and a 2nd semiconductor clad layer are laminated, a directional coupler is composed of the two nearby three- dimensional optical waveguides which are formed on the semiconductor substrate, and a means which applies electric fields to them independently is provided. Denoting the lengths to the TE and TM modes which are required for the complete movement of the waveguide light power from one of the two nearby three-dimensional optical waveguides to the other optical waveguide as LTE and LTM, the element length L of the directional coupler is nearly equalized to LTE and LTM. Consequently, element size of <=1mm is obtained.

IPC: B01D25/12
Filed: 1989-08-21
Abstract: PURPOSE:To efficiently clean a filter cloth by providing a stop valve for controlling the supply of a slurry to a dehydrating filter press to a slurry feed pipe, measuring the water content of a dehydrated cake and stopping the supply of the slurry to the filter press. CONSTITUTION:A solenoid valve 9 is opened, a solenoid valve 12 is closed, and a slurry is supplied between the filter plates collected on the upstream side, placed on one another and pressed. When a cake is formed, the supply of the slurry is stopped, then the filter plates are opened, and the cake is removed. At this time, the water content of cake is measured by a moisture meter 14. When the water content measured by the meter 14 exceeds the specified set value, a signal is inputted to a controller 15 from the meter 14, and a signal is outputted from the controller 15. Consequently, a pump 13 is operated to supply pressurized industrial water to the dehydrating filter press 7. The filter cloth is cleaned in a short time in this way.

Title: Extracting device for correction candidate character of japanese sentence
Inventor: TAKAGI SHINICHIRO
IPC: G06F17/27
Filed: 1988-08-29
Abstract: PURPOSE:To improve the correcting accuracy of auxiliary positional words by taking out a case element that secures the coincidence between the noun category of each case element and the noun category of a noun word and extracting the case auxiliary postpositional words corresponding the case elements as the correction candidate characters. CONSTITUTION:A noun/verb connection inspecting part 5 detects the connection part between a noun and a verb or the connection part where an unknown HIRAGANA (cursive for of Japanese syllabary) exists between a noun and a verb. The noun/verb connection state detected by the part 5 is received by a correction candidate character extracting part 6. Then the ommision of an auxiliary postpositional word is decided for the connection part between a noun and a verb; while a wrong auxiliary postpositional word is decided for the connection part where an unknown HIRAGANA word exists between a noun and a verb. A case element pattern table 10 produced previously is retrieved with a verb word header or a term type noun header used as a key. Thus a case element that secures the coincidence between the noun category of each case element of a word and the noun category of the corresponding noun word is extracted, and the case auxiliary postpositional word corresponding to the extracted case element is extracted out of a case auxiliary postpositional word candidate table 11 as a correction candidate character. Then a corrected Japanese character string is outputted to a Japanese document data base 12.

Abstract: PURPOSE:To improve the detecting accuracy during the pulsation, by opening the outlet of a by-pass line containing a hot wire in a slit form and rectangularly to an air flow path and linking the inlet and outlet of the by-pass line via a circular path. CONSTITUTION:The inlet of a by-pass line 4 containing a hot wire 5 for detection of air flow is opened in the direction same as the intake direction of a primary air flow path 2b. The outlet of the line 4 is opened in a slit form 7 and rectangularly to the intake direction. These inlet and outlet are linked to communicate with each other via a circular path 4b. As a result, the width is decreased for the opening 7 provided at the narrowest part of a Venturi part 3 having a low level of dynamic pressure, and at the same time the effect due to the intake pulsation is reduced. Therefore it is possible to detect the intake air flow rate with high accuracy even during the pulsation.

Filed: 1986-09-12
Abstract: PURPOSE:To perform fine monitoring by displaying specific information repeatedly at a specific position on a screen together with a photographed image on a monitoring TV when an intruder is detected. CONSTITUTION:Fixation information when a TV camera 1 is set and intruder information are set by a setting device 10 and stored in a memory 11.

Title: Information storage medium
Inventor: OOTOMO JIYUNICHI
IPC: G11B7/24079
Filed: 1983-11-16
Abstract: PURPOSE:To execute stably a tracking by varying locally a width of at least a part of a group for tracking, and storing the information. CONSTITUTION:A group 2 for tracking is formed in a shape of a concentric circle or in a shape of a spiral on a substrate 1, its width is narrowly formed locally, and a part corresponding to an information signal becomes a narrow width part 3. A reflected light of a light condensed onto the substrate 1 is diffracted by the group 2, too, and the reflection factor drops against a completely flat surface, but the reflection factor further drops in the narrow width part 3. It is because the light is diffracted by a phase difference of a step of the group 2, and simultaneously, the diffraction in an edge part scatters above an opening of an objective lens 7, and the reflection factor is lowered. Therefore, if this reflected light is received by a photodetector 7 and a difference of its reflection factor is brought to a signal modulation, a format information signal can be reproduced. Also, the group 2 is formed continuously, therefore, a tracking can be executed stably enough.

Abstract: PURPOSE: To obtain electrostatic attraction method and apparatus for supporting a wafer to be processed by plasma in which neutralization of the wafer is detected surely and the wafer is transferred reliably. CONSTITUTION: An aluminum electrode 10 is deposited with an alumina insulation film 11 to constitute an electrostatic attraction electrode 12 which is then connected with a DC power supply 13 for applying negative and positive voltages alternately, a switch 14, and an integration circuit 15 through a low- pass filter 16. The integration circuit 15 integrates a leak current flowing through the alumina insulation film 11, a wafer 1, and a plasma 6 when a negative voltage is applied to the electrode 12 while attracting the wafer 1. Neutralization of the wafer 1 is ended at a moment in time when the integrated value matches the leak current flowing upon application of a positive voltage while releasing the wafer 1, i.e., when the output from the integration circuit 15 goes 0V.
