Title: Fuel cell electrode and manufacture thereof
Inventor: MAOKA TADANORI
IPC: H01M4/96
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To provide a fuel cell electrode with high durability to impurities in a fuel gas such as CO even when the concentration of CO in the fuel gas is high, or even when a fuel cell is operated at relatively low temperature. SOLUTION: A catalyst is formed with Pt supported on carbon and noble metal Pd on one surface of a porous carbon plate to form an electrode. The electrode is immersed in the dilute solution of a chloride or a sulfide of a base metal element X which is easy to adsorb oxygen. By adding a liquid phase reducing agent into the dilute solution, the base metal element is deposited by reduction on the electrode surface. The layer of the base metal element is made extremely thin in a single atom level or a fine particle level. Since a CO molecule is not adsorbed on the base metal atom, the adsorption amount of CO is very small. Since a water molecule adsorbed on the base metal element functions as an oxidizing agent of CO, oxidation removing reaction of CO is easy to occur.

Abstract: PURPOSE:To obtain good weld beads by adding parameters to arbitrarily change a welding speed and welding torch angle to the corrugation shape to be previously inputted as an NC parameter and controlling both at the time of welding by a delayed control system to precede a sensor to a welding robot.

Title: Optical information recording medium
Inventor: NISHI SHINICHI
IPC: G11B7/24
Filed: 1984-08-28
Abstract: PURPOSE:To permit high-performance recording to be performed by sufficiently raising the adhesion of a recording layer to supporter by forming the layer in contact with the supporter from a compound having at least a glycidyl group. CONSTITUTION:In an optical information recording medium consisting of a supporter 1, a reflective recording layer 4 with dispersed metal fine particles in a laminate form, the layer in contact with the supporter 1 is made of a compound with at least a glycidyl group, thus enhancing the absorbability of high-density energy beam 6 by the recording layer. High-performance recordng can thus be attained, and high-performance reading can also be made because of the increased reflectivity. The sensitivity and the SN ratios can also be greatly raised. Since the adhesion of the recording layer to the supporter is sufficient, bits 7 of high shape accuracy can be formed by high-density energy beam 6 for recording and the failure of formation of bits 7 can be prevented. Highly sensitive and highly reliable recording over the whole of the recording layer can be obtained.

Abstract: PURPOSE:To manufacture a device having less potential drop of a channel region and an excellent transfer efficiency by providing the step of recovering on the concentration change caused in a section to become a channel region of a charge transfer region produced at the time of forming a channel stopper. CONSTITUTION:A P-type well impurity is ion-implanted to a predetermined section of a P-type semiconductor substrate 1, and diffused to form a P<+> type channel stopper 2. Then, the surface of the substrate interposed between isolating oxide films 3 and exposed is thermally oxidized to form an oxide film 4. The high concentration region of the stopper 2 intruded to a section which becomes a buried channel region under the region 4 is relatively reduced in its concentration by impurity atoms to be implanted by the concentration difference from the formed film 4. The concentration of this section is so rotated as to approach the concentration of the substrate 1. Here, the film 4 is removed by etching, and the surface of the substrate to become a buried region is reexposed. P or the like is implanted to the exposed substrate interposed between the films 3, diffused to form an N<-> type buried channel region 5, a thin oxide film is formed on the exposed section, and a gate electrode 6 is formed.

Title: Musical sound synthesizer
Inventor: KUNIMOTO TOSHIFUMI
IPC: G10H7/08
Filed: 1989-07-12
Abstract: PURPOSE:To control pitch at relatively short intervals while fixing a clock frequency by accumulating a delay time information value according to a fixed clock and using a carry output which is generated every time the accumulated value reaches a specific value as a control clock for driving a delay means. CONSTITUTION:A control circuit 5 inputs an F number (delay time information value)  F corresponding to the pitch of a musical sound to be generated to a phase accumulator 1, which accumulates the F number  F every time a frequency-fixed system clock phi is inputted from a clock generator and generates the carry output C01 when the accumulated value reaches the specific value. In a delay feedback processor 2, a delay circuit operates with the carry output C01 sent out of a phase accumulator 1 as the control clock to delay data inputted through an adder by a time corresponding to the control clock C01 and output the delayed data. Consequently, the pitch of the musical sound which is generated can be controlled freely and accurately while the characteristic frequency is held.
