Title: Method and system for automatically controlling frequency and cdma receiver
Inventor: ONO SHIGERU
IPC: H04B1/707
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To highly accurately estimate frequency offset by transforming a pilot symbol into complex vector expression, for which the information modulation component thereof is canceled, and adding that complex vector expression at least in two ways in common mode over a predetermined symbol block. SOLUTION: An inverse spreading part 220 inversely spreads a reception digital signal supplied from an A/D converting part 103 and converts it to a QPSK symbol. An inverse pilot modulating part 230 separates a QPSK symbol supplied from the inverse spreading part 220 to a pilot symbol and a data symbol. The pilot symbol inversely converted by the inverse modulating part 230 is made into complex vector expression for the unit of a symbol and outputted to an inversely modulated pilot symbol common-mode adder 510. This complex vector is added in common mode by the common-mode adder 510 and outputted to an addition synthesizer 520 later. The addition synthesizer 520 adds the output of the common-mode adder 510 and outputs it to a frequency offset estimating part 530.

Filed: 1990-07-13
Abstract: PURPOSE:To obtain a high speed printer with little vibration by a method wherein in the printer which swings a printing head normally to a paper feed direction to perform printing, at least three or more independent printing heads are provided, and adjacent heads are made to swing with a specific phase difference. CONSTITUTION:Adjacent printing heads among independent N printing heads are made to swing sinusoidally on with same cycle by a phase difference of 2pi/N. In the case where a printer is composed of three printing heads, the heads 1-3 own a carriage shaft 5 jointly, and each owns independently a carriage 4 and a connecting rod 5. Where a swing piece amplitude of the head is made A and a distance between the heads is made B, coordinates y1-y3 in a carriage shaft direction of the heads 1-3 at time t are obtained, and exciting force by swing of the heads 1-3 is obtained form that and mass (m) of the head. Then, a sum thereof, i.e. exciting force of all the machine, becomes zero, almost balances on the carriage shaft, and vibration is not generated. Further, though a head swing amplitude 2A is larger than the distance B between the heads, it becomes capable of being established that the heads do not interfere with each other.

Title: Information communication system
Inventor: OGAWA KATSUHIKO
IPC: H04K1/00
Filed: 1993-07-26
Abstract: PURPOSE:To peruse information without paying any price within the limitation range of time or information quantity by deciphering ciphered information just for the previously decided time or information quantity. CONSTITUTION:Information 1 is subjected to encipherment by an encipherment part 2 and outputted. Assuming that the limitation range of deciphering time for one minute is stored in a limitation part 7 in this case, the ciphered information and a key 4 are respectively transmitted by an information communication part 3 and a key communication part 5. The transmitted key 4 is stored in a deciphering key part 6. A deciphering part 8 decodes the transmitted and ciphered information by using the key 4 stored in the deciphering key part 6 and outputs it as information 9. But as the lapse of time stored in the limitation part 7, namely, one minute after the start of deciphering, the key 4 stored in the deciphering key part 6 diminishes, so that the deciphering part 8 does not perform deciphering after that, and outputs it as the information 9.

Abstract: PURPOSE:To form a normal photosensitive pattern having no defect by purifying a surface photosensitive face of an object to be exposed by an air blow mechanism which is capable of removing effectively dust on the surface of a plate- like object and thereafter exposing a prescribed pattern to form a normal photographed pattern without defects.

As for the glass plate moving on the transfer mechanism, dust on the upper photosensitive face is blown away by a blow mechanism 7 and purified. Accordingly, no dust exists on the upper face of the glass plate 1 which reaches the holder 2. Therefore, after the exposure, the vacuum adsorption holding of the glass plate 1 is stopped, and thereafter, a shooter is operated, and the glass plate 1 is moved onto the transfer mechanism 6 and is contained in the cartridge 4. As a result, an exact photosensitive pattern having no defect can be formed.

A drawing (a) shows the surface condition of the object M, and a drawing (b) shows an output waveform. As shown, a pulse having a large peak value is obtained as an output. An electrical scanning can be conducted, whereby a scanning speed is very fast, and the surface of the object to be measured which is running can be totally scanned by a beltlike laser light. Additionally, the CCD camera is used in this case, but the other means such as an image sensor of an MOS may also be used. The point is that any device will do so long as it is an electronic scanning type image sensor.
