Title: Automatic frequency control circuit for time division multiplex communication
Inventor: TOYOMANE AKIRA
IPC: H04L7/033
Filed: 1990-03-14
Abstract: PURPOSE:To respond to fading proper to a mobile communication line by realizing an AFC circuit by using a memory circuit which updates a frequency controlled variable based on the carrier frequency offset of each slot of one TDMA frame. CONSTITUTION:A DC mean value that is the component of the reception carrier frequency offset  f1 of the slot 1 is detected at a DC mean value detection circuit 3, and is inputted to the memory circuit 4 as a frequency offset component, and is subtracted from an output value fed back from the register 1 of a shift register 43 by an adder 42, and is stored and held as being shifted to registers N, N-1,..., 1, then, it goes to the frequency controlled variable of the slot 1 of the next frame. By repeating such operation, the frequency control of the slot 1 is performed. The frequency control for the slots 2-N is performed similarly.

Title: Gas laser device
Inventor: OKAMOTO NOBORU
IPC: H01S3/097
Filed: 1989-03-14
Abstract: PURPOSE:To prevent any adherence of dust to a mirror by forming an isolation chamber at an inner side of at least either of a totally reflecting mirror or an output mirror after demarcating it and making a gas laser medium that is cleaned by a dust removing means flow in the isolation chamber. CONSTITUTION:One end part of the side of an output mirror 14 in a laser tube 1 is partitioned into an isolation chamber 22 by a diaphragm 21. A through hole 23 which allows laser light emitted by a main electric discharge to pass through is provided in the diaphragm 21 by boring the diaphragm; besides, an electrostatic precipitator 24 is installed as a dust removing means at a part facing an axial one end of the first blower 19 which acts as the first circulating means.

After dust in a part of a gas laser medium circulating in the laser tube 1 is removed by the first blower 9 through the electrostatic precipitator 24, the cleaned gas laser medium is fed to the isolation chamber 22. Adhesion of dust to the inner surface of the mirror 14 is thus prevented.

IPC: G01F1/32
Filed: 1979-05-18
Abstract: PURPOSE:To reduce the cost of repairing for a vortex detecting element, and produce the vortex  detecting element and a vortex generating element at a high efficiency, by detachably setting the vortex detecting element in the vortex generating element. CONSTITUTION:A through bore 7 is provided in a vortex generating element 1 such that the bore  7 is extended through both side surfaces 5, 6, where a vortex is generated, of the element 1, and a vortex detecting element 8 is detachably fitted in the bore 7. A Karman's vortex street is successively generated at both sides of the vortex generating element 1 due to the flow of a fluid in the direction of an arrow A in a passage 3. Metallic diaphragms 12, 13 are displaced due to the  vortexes so that the distance between the diaphragm 12 and a metal plate 15 and the distance  between the diaphragm 13 and a metal plate 16 are varied. As a result, electrostatic capacities of  these diaphragms 12, 13 are varied. Variations in electrostatic capacities referred to above are electrically detected through lead wires 19-21 to determine a vortex generating frequency, i.e.  the velocity of flow or flow rate of a fluid in the passage 3. Since the detecting element 8 can be withdrawn from the through bore 7 so as to be renewed, a detector 30 can be repaired easily.  Moreover, the detecting element 8 and generating element 1 can be produced separately. Therefore, the detector 30 can be produced at an extremely high efficinecy.

Title: Tracking error detector
Inventor: NOSE AKIO
IPC: G11B7/09
Filed: 1990-03-13
Abstract: PURPOSE:To eliminate an offset by adjusting a level of a light receiving signal so that the level of the light receiving signal by a succeeding subbeam is larger than the level of the light receiving signal by a preceding subbeam under the condition of a same light receiving quantity thereby cancelling the difference of the reflected luminous quantity between the preceding subbeam and the succeeding subbeam. CONSTITUTION:A spot 21a of a main beam 21 is formed on a track 48 to break a metallic recording film thereby forming a pit 50. Spots 22a, 23a of subbeams 22, 23 are formed respectively to positions deviated by a prescribed interval to the left and right in the lengthwise direction of tracks 48. In this case, since a preceding subbeam 22a passes through an unrecorded part, the reflected luminous quantity is large and since a succeeding subbeam spot 23a passes on the forming pit 50a, the reflected luminous quantity is less. Since the light receiving signal level of the succeeding subbeam 23 is amplified by a variable amplifier in this way, no offset is caused and a recording main beam spot 21a traces on the center of the tracks 48.

Title: Binary coding device
Inventor: YAMAGUCHI SHINGO
IPC: H04L25/03
Filed: 1982-04-14
Abstract: PURPOSE:To binary coding a video signal with high image resolution, by comparing the video signal with the threshold level and then switching the threshold value of a binary coding device in >=2 steps by a delay output of the above- mentioned comparison and in response to the level of the video signal set before a prescribed time. CONSTITUTION:The video signal supplied to a terminal 1 is held at a sample holding circuit consisting of a diode D, a capacitor C and a resistance R. Then the voltage VP proportional to the holding voltage is delivered to the output of an amplifier 4, and a comparator 6 delivers a level of 1 or 0 is accordance with whether the video signal is higher or lower than the reference level VR at the joint between resistances R4 and R5. The result of this comparison is given to an FET8 via a flip-flop FF7 which functions as a delay element. The FET8 is turned off or on in accordance with whether the level of the picture element immediately before the noticed picture element is higher or lower than the level VR. In response to the level of the picture element, the threshold level of a binary coding comparator 5 is switched in 2 steps. This can obtain an output that gives good binary coding to thin characters, etc. in a white background.

IPC: H04N19/85
Filed: 1989-03-15
Abstract: PURPOSE:To visually reduce discontinuous distortion between neighboring blocks by providing a picture element (inter-block picture element) which is neither block-coded nor transmitted between the neighboring picture element blocks when the picture element block is generated at a transmitting part, and reproducing and supplementing it by using the neighboring picture element block at a receiving part. CONSTITUTION:A digital picture signal series X of 384 (number of picture elements per one line) X 480 (number of lines)-pieces per one block inputted to a block coding transmitting part is decomposed into 8X8-picture element blocks xi by a block generating part 10. This picture element block xi is constituted so that, for instance, every one piece of the picture element (inter-block picture element) not included in the picture element block exists between the picture element blocks. The total number of the picture elements per one block in this case becomes 2322-pieces, and it comes to be decreased compared with the case of a traditional block coding transmission device (2880-pieces). The picture element block xi (i=0 to 2331) are converted into 8X8-conversion coefficient blocks Ai (i=0 io 2321) by two-dimensional discrete cosine transformation (DCT) at a converting part 11.

Title: Speech recognition system

IPC: G10L15/28
Filed: 1991-03-04
Abstract: PURPOSE:To reduce erroneous recognition due to an environmental noise in the periphery with comparatively easy processing and simple constitution. CONSTITUTION:The feature quantity of sound inputted from an ordinary microphone 1a and a skeleton conducting type microphone 1b are extracted by feature extraction parts 2a, 2b, respectively, thence, they are inputted to interval detecting parts 3a, 3b, and interval detection are performed. Interval information and feature quantity detected by the interval detecting parts 3a, 3b are inputted to a control part 4, and an interval detected as the sound by the microphone 1b out of the intervals detected by the microphone 1a is assumed as a correct sound interval. Thereby, it is possible to prevent a pattern collation from being performed by judging a tone other than the sound emitted from a user as the sound erroneously. Also, since possibility to omit the high frequency component of the sound only by the interval information of the microphone 1b exists, the interval information of the microphone 1a is used.
