Title: Production of antimicrobial pottery
Inventor: MATSUMOTO YUKIO
IPC: C04B33/24
Filed: 1994-09-01
Abstract: PURPOSE: To obtain pottery having an excellent antimicrobial property with good productivity at a low cost by printing the surface of a pottery type body or the surface of the glazing layer formed on this surface with a liquid contg. silver (compd.) to make the prescribed amt. of the silver adhere thereto, then firing the body. CONSTITUTION: A liquid contg. silver and/or a silver compd. (example; silver nitrate) is made to adhere to the surface of the pottery type body or the surface of the glazing layer formed on the surface of the pottery type body by printing, and the silver adhesion on the body surface or the glazing layer surface is specified to 0.1 to 200mg/cm<2> . The pottery body is then fired, by which the antimicrobial pottery is obtd. The liquid contg. the silver and/or the silver compd. is preferably a suspension of the silver and/or the silver compd. or glaze or colors, etc., mixed with the silver and/or the silver compd. Since the silver-contg. liquid is adhered by printing, the uniformly adhering layer is formed with good production efficiency. This process for producing the antimicrobial pottery is effective for producing tile, Japanese and western tableware, etc.

Title: Transmitter and transmission method
Inventor: WATANABE HIDEKAZU
IPC: H04B7/26
Filed: 1994-08-10
Abstract: PURPOSE:To maintain high demodulation efficiency independently of a fading state by generating the same pattern data as known pattern data in transmission data at a receiver side and using an adaptive filter whose tap number is made variable so as to demodulate reception data. CONSTITUTION:A high frequency RF signal processing circuit 3 uses an RF/IF/ detection circuit 3A to apply high frequency amplification to a reception signal and applies orthogonal detection to the signal. Then the signal is converted into a digital signal by an A/D converter circuit 3B and the signal is given to a MODEM/data processing circuit 4. The circuit 4 demodulates received data by signal processing in a demodulation digital signal processor DSP 4A and executes periodic processing such as fetch processing, equalization processing, demodulation processing and error correction processing. The number of taps of the adaptive filter used for equalization processing is made variable and the adaptive filter after becoming variable is used to demodulate reception data. Thus, even when the reception data are received under an environment having lots of distortion due to fading, the data are demodulated at a low bit error rate.

Title: Production of copper foil for printed circuit
Inventor: MURAKAMI MASAOMI
IPC: C25D5/18
Filed: 1994-08-11
Abstract: PURPOSE:To establish a technique for producing copper coil for printed circuits capable of easily and cost effectively controlling the surface roughness of a copper foil matte surface. CONSTITUTION:A DC current having ripples of a pulsation rate of >=5%, more preferably >=20% is used as an electrolytic current in production of the electrolytic copper foil by filling an electrolyte contg. copper ions between a horizontally rotating cathode cylinder and an anode arranged to face this cathode cylinder and effecting electrolysis to electrodeposit copper on the cathode cylinder, then peeling the electrodeposited copper to a foil form. The waveform of the ripple currents is regulated by the pulsation rate, i.e., the ratio (i1/i2) of the ripple current value to the average current value and period (T). Control of the pulsation rate is executed by changing the secondary voltage of a transformer of a DC power source by a thyristor phase control system or changing to make the ratio of the current rectification output small in the pulsation rate and the current rectification output large in the pulsation rate and mixing both outputs. The nucleus generation in the initial period of copper electrodeposition is accelerated and uniform crystal growth is effected if the pulsation rate is made larger. The surface roughness of the matte surface is thus controlled small.
