Abstract: Provided is a method for manufacturing a catalyst with which it is possible to obtain a supported metal ammonia synthesis catalyst, in which there are restrictions in terms of producing method and producing facility, and particularly large restrictions for industrial-scale producing, in a more simple manner and so that the obtained catalyst has a high activity. This method for manufacturing an ammonia synthesis catalyst includes: a first step for preparing 12CaO·7Al2O3 having a specific surface area of 5 m2/g or above; a second step for supporting a ruthenium compound on the 12CaO·7Al2O3; and a third step for performing a reduction process on the 12CaO·7Al2O3 supporting the ruthenium compound, obtained in the second step. This invention is characterized in that the reduction process is performed until the average particle diameter of the ruthenium after the reduction process has increased by at least 15% in relation to the average particle diameter of the ruthenium before the reduction process.

Abstract: An electrolytic cell capable of simply electrolyzing carbon dioxide into carbon monoxide and oxygen with low activation energy, and an electrolytic device. The carbon dioxide electrolytic cell includes a cathode, an anode, and a solid electrolyte having oxide ion conductivity. The cathode is the following (A) or (B); (A) a metal and a first mayenite-type compound are included therein or (B) a metal and a second mayenite-type compound are included therein, said second mayenite type compound including a mayenite type compound having electron conductivity.

Abstract: A simple approval administration system and a method which can reliably administrate information regarding proposal and approval are provided. A proposer terminal sends proposal data to a host server, which stores the proposal data on a proposal DB 110 by correlating the proposal data with an administration ID and sends permission to print a proposal form to the proposer terminal. The proposer terminal 200 prints the proposal form (paper document). After confirming the content of the proposal form, a user of an approver terminal 300 approves the content of the proposal form and then sends approval information to the host server 100. The host server 100 stores the proposal data (on which the approved information is stored) on the master DB by correlating the proposal data with the administration ID and sends permission to print the approved proposal form to the approver terminal, which prints the approved proposal form (paper document).

Abstract: An occupant restraining webbing employed in a seatbelt system for a vehicle includes warp which has a dry tenacity of 8.8 gr/De or more, a thickness of 1,700 De or less and a twist multiplier of 3,100 to 5,500. Thus, it is possible to reduce the extra amount by which the webbing is undesirably wound off after the rotation of a takeup shaft for winding off the webbing from a webbing retractor has ceased.

Abstract: A tape player of small size and weight capable of detecting the end of the tape with a simple mechanism and automatically shutting off the tape player when the end of the tape is detected. The tape player includes a drive gear driven by a motor; a fast speed gear, which drives the tape during the rewind and fast forward modes; and a normal speed gear, which drives the tape during the record and playback modes. The drive gear, fast speed gear, and normal speed gear are mounted on the same spindle and are connected by coupling means that cause the gears to rotate together until the end of the tape is reached. The normal speed gear is connected via a friction coupling to a bias lever that forces cam following means on a shut-off lever to follow an eccentric cam on the drive gear.

Abstract: A tape cassette loading device comprises a chassis on which a tape cassette is mounted, a pair of guide pins protruding from the chassis and capable of being fitted in guide holes of the tape cassette in a loaded position, a taper surface formed around the guide pin at a given height above the chassis so as to be tapered toward the extended end portion of the guide pin, and an ejection mechanism facing the front portion of the bottom surface of the tape cassette in the loaded position and capable of advancing and retreating along the guide pin. In the final ejected position the cassette rests on the upper tapered portion of the guide or guides.

Abstract: A dual-purpose production plant for cold rolled steel sheets and hot-dip galvanized steel sheets having, successively disposed in series, a heating zone, a soaking zone, a primary cooling zone, an overaging zone equipped with a controlled cooling facility, a molten galvanizing zone, an intermediate cooling means, a secondary cooling zone, a temper rolling means, and a chemical treatment means, and a bypass for directly connecting the overaging zone and the secondary cooling zone with each other.

Abstract: A cassette tape recorder comprises a locking mechanism for locking operation sliders for keeping a tape recorder mechanism in a desired operation mode, a stop operation lever for releasing the lock effected by the locking mechanism and for bringing said tape recorder mechanism to a stop mode, an ejecting lever for ejecting a cassette tape in a cassette mounting part of said tape recorder mechanism, and an ejection control mechanism which is controlled by said operation levers, to be non-engageable with respect to said ejecting lever when the operation slider is locked and to be engageable when the operation slider is not locked, said ejection control mechanism operating the ejecting lever to eject the cassette tape through the locking mechanism by a stop operation when it is engageable and when said stop operation lever is operated.
