Title: Correlation demodulator
Inventor: KOMATSU YUJI
IPC: H04J13/00
Filed: 1989-05-31
Abstract: PURPOSE:To attain correlation demodulation whose communication efficiency is not lowered by providing a controller which implements search and tracking processing in correlation demodulation according to an efficient algorithm. CONSTITUTION:A controller 14 reads registers 10-12 to detect a detection level being the output of reset integration devices 7-9 sequentially, stores the content into a memory, retards the clock phase of a clock generator 13 by one tip and repeats the same operation. Then plural phases corresponding to larger reception levels having larger reception levels stored in the memory are selected to be candidates of obtained synchronization phases. Then the clock generator 13 is set to the phase of the selected candidate, and the reception level inputted and integrated is compared with a prescribed synchronization deciding level and when the reception level is smaller than the discrimination level, the similar comparison processing is repeated as to the next candidate phase and when larger, it is discriminated that the synchronization is complemented at the phase and the processing is transited to the tracking. Thus, the efficient correlation demodulation is always attained.

IPC: H04N7/00
Filed: 1979-10-24
Abstract: PURPOSE: To expand the range of the utility of microfilm retrieval by exercising control so that picture information on a retrieved microfilm can be transmitted to any terminal device.  
     CONSTITUTION: The subscriber's number of a terminal device which should receive a picture signal, e.g. terminal device 7a and retrieval information on a desired microfilm are inputted from keyboard 5. Next, terminal device 4 sends the retrieval information, required by terminal 7a, to picture signal transmitter 2 through the exchange. Transmitter 2 supplies the retrieval information to micro image file MIF1. Then, MIF1 performs retrieval on the microfilm on the basis of the retrieval information and, after the retrieval, sends the result to transmitter 2. Transmitter 2 operates exchange 3 to connect terminal device 7a to the circuit and sends the obtained picture signal to terminal device 7a. Terminal device 7a receives this picture signal and generates and outputs its hard copy.

Title: Production of mycelium of tricoderma matsutake or grifola frondosa
Inventor: UENO SABURO
IPC: A23L27/10
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for rapidly and simply producing the mycelia of Tricoderma matsutake or Grifola frondosa. SOLUTION: This method for producing the mycelia of Tricoderma matsutake or Grifola frondosa comprises culturing the mycelia of Tricoderma matsutake or Grifola frondosa in a culture medium containing a vegetable extract and/or an organic acid. The mycelia of Tricoderma matsutake can efficiently be cultured by using the culture medium. When the mycelia is cultured, the homogenization of the mycelia and the subsequent conditioning culture of the homogenized mycelia in the culture medium gives a largely improved culture rate. Consequently, the conventional culture of the Tricoderma matsutake mycelia requiring many months can be shortened to about 10 days, and the utilization of the Tricoderma matsutake mycelia to foods can largely be expanded.

IPC: C07F9/11
Filed: 1984-07-04
Abstract: PURPOSE:To obtain the titled substance economically, reutilizing the recovered phosphoric acid, and facilitating the separation and purification of the product, by reacting a specific (un)saturated aliphatic alcohol with a polyphosphoric acid in a hydrocarbon, and extracting the obtained reaction mixture with a solvent composed of a lower alcohol and water. CONSTITUTION:1mol of a 8-36C (un)saturated aliphatic alcohol (e.g. dodecyl alcohol) is made to react with 2-10mol of a polyphosphoric acid having a concentration of 100-116% in terms of orthophosphoric acid, in one or more solvents selected from 4-8C saturated aliphatic hydrocarbons (e.g. n-hexane) and 5-7C saturated alicyclic hydrocarbons (e.g. cyclohexane). A 1-4C alcohol and water are added to the reaction mixture to effect the migration of the orthophosphoric acid to the layer of the lower alcohol and water. The orthophosphoric acid separated efficiently from the monoalkylphosphoric acid by this process is concentrated and reused. The objective substance can be obtained by distilling off the solvent, the lower alcohol and water from the oil layer rich in the monoalkylphosphoric acid.

Patent JP-H034161-A (JP)
Title: Nonsaturation electrometer
Inventor: MATSUMOTO SHINGO
IPC: H03F1/30
Filed: 1989-05-31
Abstract: PURPOSE:To improve the response to an input signal and to improve the separability by preventing saturation from being caused in an amplifier against an excessive input signal. CONSTITUTION:A level monitoring circuit 2 monitors the output level of an amplifier A1 and when the output level does not reach a previously set constant level, a feedback circuit 4 is not also activated so that an input signal Is is amplified and outputted as it is. When the input signal Is increases and the output level of the amplifier A1 reaches the previously set constant level, the feedback circuit 4 is activated by receiving the output signal of the level monitoring circuit 2 to apply a signal Ib having the opposite polarity from the input signal Is to the input terminal of the amplifier A1. Consequently, the output of the amplifier A1 does not exceed the previously set level and operation in a saturation range is precluded. Consequently, a speedy response to the input signal right after an excessive input signal can be made and the separability of an analyzing machine can be improved.

Title: Print document authentification device
Inventor: ROSS GARY A
IPC: G07D7/16
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a new system for authentificating a print document. SOLUTION: This system authentificates a bank bill by checking projection printing generated by engrave print processing generated only on a true bank bull. Each paper money 36 is individually transported so as to pass between a pair of brushes 38 contacting rough bristles on both the sides of paper money. In order to sense the noises of a brush means which are increased when there is projecting printing, a microphone 28 is installed in proximity to this brush means. Outputs provided from these microphones 28 are digitized and impressed to a data processing means 22. The data processing means 22 generates a value based on the digitized outputs of microphones 28 and compares that value with a stored value so that it can be determined whether the relevant paper money includes the projecting printing or not, therefore, whether the relevant paper money is true or not.

Title: Printer having picture data conversion function

IPC: B41J2/485
Filed: 1988-06-07
Abstract: PURPOSE:To shorten the data transfer time by converting a picture data again according to the specified relationship of conversion and controlling a printing means so as to change over the presence of the printing of a unit printing pixel on the basis of the picture data converted again. CONSTITUTION:When a data output from an interface means M3 is represented by the pixel data of a corresponding type on the basis of the specified relationship of conversion of the unit of the data and a unit printing pixel, the pixel data is converted again according to the fixed relationship of conversion by a pixel-data conversion control means M24 mounted to a control section M2, and a printing means M1 is controlled so as to change over the presence of the printing of the unit printing pixel on the basis of the pixel data. Even when the unit of a pixel data output from the interface means M3 and the unit printing pixel do not correspond at 1:1 in the pixel data, the picture data can be printed by the printing means M1 because the unit can be made to correspond at 1:1 with the unit printing pixel by the control section M3, and the quantity of data transfer of the interface means M3 can be reduced.
