Title: Production of alumina porous material
Inventor: OSHIMA HITOHIDE
IPC: B01J20/08
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To efficiently produce an alumina porous material, having an optional pore diameter, a large pore volume and capable of providing a sufficient permeation rate by converting a sol prepared by hydrolyzing an aluminum alkoxide into a gel and then carrying out a specific treatment. SOLUTION: An aluminum alkoxide (e.g. aluminum sec-butoxide) is hydrolyzed to provide an alumina precursor sol, which is then converted into a gel. The resultant alumina precursor gel is subsequently kept at a temperature below the boiling point of a solvent (e.g. 2-methoxyethanol) in the aluminum alkoxide solution to replace the solvent in pores and voids of the alumina precursor gel in a state of a wet gel with an organic solvent that is a dispersion medium, preferably at least any one of compounds of the formula, Cn H2n+1 OH [(n) is 2-4, except tert-C4 H9 OH] and acetone. The resultant gel is then supercritically dried (dried by using CO2 as the dispersion medium) to remove the organic solvent and the resultant dried alumina precursor gel is subsequently baked.

Title: Alkaline storage battery
Inventor: OGASAWARA TAKESHI
IPC: H01M4/52
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To improve active material availability, especially during high- temperature charging, by solving magnesium at a specific concentration in an alkaline electrolyte provided with un-sintering nickel electrode having nickel hydroxide as an active material, and a negative electrode. SOLUTION: Magnesium contained in an alkaline electrolyte by 0.05-10 mg/l enters small holes among nickel hydroxide particles mainly in a first charge to increase its oxygen over voltage, and therefore, waste of charging electricity quantity caused by oxygen generation is prevented to improve charging efficiency. As the alkaline electrolyte, aqueous solution containing 4.0-10.0 mol/l potassium hydroxide, 0.2-1.0 mol/l lithium hydroxide, 0.2-2.0 mol/l sodium hydroxide, is suitable, and as a negative electrode, a zinc electrode, a cadmium electrode, or a hydrogen storage alloy electrode is suitable. Nickel hydroxide in which one or more Zn, Mg, Ca, Mn, Al, Cd, Cu, Y, Co, Bi, La, Yb, En, Gd, and Ce are solid solved by 0.5-10 wt.% to total amount with Ni is suitable because of less decrease of a charging amount.

Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To facilitate comparison before and after the change of a logical operation expression by attaching an intrinsic logical operation element number to respective logical operation elements stored in a logical operation element data base independent of the execution order of the logical operation expression. SOLUTION: A logical operation part 20 performs a prescribed logical operation of logic signals sent from an input signal processing part 10 and outputs them to an output signal processing part 30. In this case, the logical operation element data base 40 describes the input/output connection information of the logical operation elements used in the logical operation part 20 and logical operation results. A logical operation element arrangement part 50 arranges the respective logical operation elements stored in the data base 40 corresponding to the execution order of the logical operation expression of the logical operation part 20. A logical operation element number imparting part 60 attaches the intrinsic logical operation element number to the respective logical operation elements stored in the data base 40.  Since the element number is determined independent of the execution order of the logical operation expression, the comparison before and after the change of the logical operation expression is easily performed.

Title: Semiconductor device
Inventor: ANDO AKIO
IPC: H01L29/78
Filed: 1987-12-25
Abstract: PURPOSE:To equalize the reproducibility of source-drain forward voltage characteristics by making the surface resistivity of the rear main surface of a substrate smaller than bulk resistivity in a vertical type MOSFET. CONSTITUTION:Insulating gates 10, channel forming regions 6 and source diffusion regions 7 are formed on the main surface of a semiconductor substrate 5, thus constituting vertical type MOSFETs. A donor impurity is doped in the opposite main surface 5' of the semiconductor substrate 5 as a drain through ion implantation or the like, and the resistivity of the opposite main surface 5' is made smaller than bulk resistivity. Accordingly, a Schottky barrier generated between the opposite main surface 5' and a back electrode 8 can be reduced, thus equalizing source-drain forward voltage(VSDF) characteristics.

Title: Remote control signal receiver
Inventor: FUKUDA TOMOYUKI
IPC: H04B10/524
Filed: 1999-11-17
Abstract: PROBLEM TO BE SOLVED: To eliminate pulse width errors which occurs, when remote control signals are demodulated from infrared-ray carrier signals. SOLUTION: An infrared-ray receiving section 201 receives infrared-ray carrier signals from an infrared-ray remote controller 100 and an infrared-ray carrier demodulating section 202 demodulates remote control signals, by integrating the received signals by means of an integration circuit composed of a capacitor and a resistor. When the section 202 demodulates the remote control signals, an error is produced in the pulse width of the demodulated remote control signals, because the discharge from the capacitor continues, even if the pulse of the remote control signals becomes low level signals.  A waveform correcting section 203 for the remote control signals integrates the remote control signals with a long time constant in the forefront section of the pulse of the remote control signals from the demodulating section 202 and with a short time constant in the terminal section of the pulse. Then the section 203 shapes the waveform of the remote control signals into a rectangular waveform, depending on the integrated results, that is, whether the results are higher than a reference level. Since the remote control signals are integrated with the long time constant in the forefront section of the pulse, such an error is eliminated.

Title: Side ditch with running-water port and ditch cover for side ditch
Inventor: KAMIKO ISAMU
IPC: E03F5/046
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a side ditch with running-water ports, in which the manufacturing cost of the side ditch can be reduced by easily manufacturing the side ditch, in which a plurality of the running-water ports are formed to an upper side face, and a ditch cover for the side ditch. SOLUTION: Since running-water ports 4 are formed at the end section of at least a unit side ditch body 1, the side ditch 1 is molded easily because cores excepting a core for the running-water port 4 for forming the running-water port 4 in an intermediate section as seen in conventional devices are made unnecessary. Dangerousness such as the falling of a leg can be avoided even to a pedestrian because the running-water ports 4 are formed to side faces, and the efficiency of water collection is improved because a fluid such as rainwater flowing down on a road surface can be collected.
