Title: Radio receiver and signal processing method therefor
Inventor: MATSUMOTO MARIKO
IPC: H04J1/00
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To attain improvement in accuracy as well while attaining the reduction of power consumption concerning a radio receiver capable of receiving the plural channels of different frequencies and selecting the reception channel through digital signal processing. SOLUTION: The power consumption is reduced by performing high-speed and low-bit sampling (a), afterwards, loading filtering through a digital filter (c) after channel selection (b) and reducing a data rate (d) and while paying attention on a narrower frequency band required for processing after demodulation to be performed after the selection of the reception channel in comparison with a frequency band enabling reception as a receiver, the number of bits is increased by utilizing the reduction effect of quantization noises caused by over sampling.

Title: Interprobot coordinate transformation matrix setting system and correction system
Inventor: NOGO HIDETOSHI
IPC: B25J9/10
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To provide a setting system for an interobot coordinate conversion matrix to simply determine a conversion matrix between robot coordinate systems which is necessary for a plurality of robots to perform coordination operation and to provide a correction system to correct an error during conversion. SOLUTION: The tip 5 of a robot 1 driven by a control device 3 is registered with the tip 6 of a robot 2 driven by a control device 4. The positions of arbitrary three points in a space are read by respective coordinate systems. A unit coordinate system, set on a basis of three points, for example, a unit coordinate system, wherein the center of an arc of circle passing through the three points is set as a home position is computed as the values of the two coordinate systems. This way computes and sets a coordinate conversion matrix from the two robot coordinate systems to the unit coordinate system and a coordinate conversion matrix between robots is computed from the coordinate conversion matrix. This constitution sets conversion from the coordinate system of the robot 1 to the coordinate system of the robot 2 and easily realizes coordination operation between robots.

IPC: G10L19/00
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a pitch extraction method permitting to eliminate an error generated when a pitch of successive speeches is extracted. SOLUTION: This method is composed of a residual error signal generation process which indicates a pitch of a speech in a frame and generates many residual error signals and a pitch generation process which generates a residual error signal satisfying a prescribed requirement of the above-mentioned many residual error signals as a pitch.

Title: Electrolyte for driving aluminum electrolytic capacitor
Inventor: YAMADA HIDEMI
IPC: H01G9/02
Filed: 1993-02-03
Abstract: PURPOSE:To prevent an electrolyte for driving aluminum electrolytic capacitors from leaking out from the capacitors even when the capacitors are used for a long time at a high temperature without deteriorating the characteristics required by the electrolyte itself and various characteristics of the capacitors by adding bishidroxymethyl nitrilotriethanole to the eletrolyte. CONSTITUTION:Bishidroxymethyl nitrilotriethanole is added to the electrolyte using an organic polar solvent as a main solvent and quaternary ammonium salt of organic acid as a solute. It is preferable to select the organic polar solvent from among gamma-butyrolactone, gamma-valerolactone, 3-methyl-2-oxazolidine-2-one, and methylformamide. Therefore, the electrolyte does not leak out from the junction between a rubber plugging body and tub terminal, since the electrolyte is stabilized in pH and the pressing force of sealing rubber body against the tub terminal does not drop.

Abstract: PURPOSE:To shorten an adjusting time without any manual work, to enhance remedy accuracy, and to improve work efficiency by measuring a dimension between both surfaces to be drawn down before a material is transferred to a multi-roll remedying machine, and automatically adjusting intervals of upper and lower rolls group. CONSTITUTION:For a material 3 to be transferred to a remedying machine 1, a dimension W between both surfaces to be drawn down, is measured by a measuring means 4 before the material 3 enters the remedying machine 1. A measured value is sent from the measuring means 4 to a control means 26, and is compared with the standard value. When the measured value is larger than the standard value, a control signal is sent to the work means of the remedying machine 1 so that the interval S between both roll groups 21 and 22 becomes large by the difference, and the roll group 21 on one side and the other roll group 22 are away each other. Also, when the measured value is smaller than the standard value, the roll group 21 on one side and the other roll group 22 approach each other in the same way. At the time of approach and being away, the interval S is displayed by digit by a rotary encoder, and the roll group 21 on one side is correctly positioned.
