Title: Color thermal transfer recording
Inventor: SAITOU TAKASHI
IPC: B41J2/325
Filed: 1983-11-14
Abstract: PURPOSE:To arrange so that thermal transfer recording may be made concurrently in several colors at high speed and the precision of color matching be improved by making the travel of transfer film among a plurality of thermal heads longer than that of a recording paper. CONSTITUTION:An array of heating elements 12 are formed at the tip of a heating element substrate 10 for a thermal head 6, and thermal heads 61-63 are installed vertically against the running surface of a recording paper 3. Thus the running pass LABC, LCDE of a transfer film 8, longer than a distance LH between heads is provided. It is necessary to carry out a delayed treatment of a picture signal in colors M and C against color Y according to a distance 61 from head Y. However, a delayed memory capacity can be lessened because the distance LH is short. In addition, position shift does not occur. The running pass length of the transfer film 8 may be a length equivalent to the combination of a single recording length LP and the pass length LH of a recording paper 3. However, it is recommended that said running pass length should be slightly longer than the afore-mentioned equivalent length so that some flexibility may by provided in the accuracy of matching the positions of transfer film 8 and heads 61-62.

IPC: B03C3/10
Filed: 1982-12-06
Abstract: PURPOSE:To reduce the weight of flexible dust precipitation electrodes formed of fibers made of a conductive material and to simplify construction by providing said electrodes and a dust disloding mechanism which dislodges the dust deposited on the electrodes by deforming it. CONSTITUTION:An endless belt-like dust precipitation electrode 11 is extended between upper and lower driving belts 9 and is put on between rolls 6 and 7. The electrode 11 is the fabric-like material formed by woven fibers made of a conductive material, such as carbon fibers, and has flexibility. The dust in the gas admitted into a body 1 is electrified by the voltage impressed on a discharge electrode 12 and is captured on the electrode 11. The attracted dust moves to the upper stream side as the electrode 11 travels so that the dust increases its thickness toward the upper stream side. Thus, the electrode 11 is bent and deformed along the roll 6 and the dust deposited thereon is thus stripped away.

Title: Machining method of fillet portion of crankshaft
Inventor: HAYASHI HIROSHI
IPC: B23P13/00
Filed: 1986-09-11
Abstract: PURPOSE:To eliminate abrasion at a portion of a grinding wheel corresponding to a fillet portion, stress relaxation and production of frictional heat at the fillet portion, by undercutting the fillet portion previously and applying high frequency quenching thus avoiding following grinding. CONSTITUTION:A fillet portion 4 for jointing a web portion 2 and a shaft portion 3 is undercut 10. Consequently, a grinding wheel 6 grinds only a grinding portion 7 of the shaft portion 3 and does not contact against the fillet portion 4, so as to leave a high frequency quenching layer as it is even after completion of grinding. Since the fillet portion 4 is not quenched after completion of high frequency quenching, the portion of the grinding wheel 6 corresponding to the fillet portion is not abraded. Furthermore, stress relaxation does not occur at the fillet portion 4, thereby bending or production of heat does not take place at the fillet portion 4 resulting in a considerable effect that the strength is not degraded.

Title: Device for preventing overheating of heater in air conditioner
Inventor: CHIKAMATSU SADAHARU
IPC: F24H9/20
Filed: 1984-10-11
Abstract: PURPOSE:To prevent the heater from overheating by constituting a heater radiating heat shielding plate of a heat sensitive part of a temperature relay so that the shielding plate is subjected to shape variation at a set temperature to receive the heater radiating heat. CONSTITUTION:A shielding plate 5 made of a shape memory alloy is so set that it changes its shape at a proper temperature. At an extraordinary time, the heat sensitive part 6 of the temperature relay 2 strongly receives the radiation of the heater 1 because the shield is removed, and the temperature of the heat sensitive part 6 rapidly rises up and acts. At the extraordinary time when the ambient temperature of the heater rapidly rises up, the shielding plate 5 undergoes a change by the abmient temperature and the heater radiation heat, and the shield of the heat sensitive part is removed whereby the radiation heat of the heater 1 is absorbed by the heat sensitive part, and a delay in the thermal response is reduced. As a result, the temperature rise in the component parts in the circumference of the heater can be suppressed.

Title: Production of acrylonitrile
Inventor: NAKAMURA HIDEAKI
IPC: C07C255/08
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To readily and inexpensively produce acrylonitrile in high yield, as the unreacting ammonia is efficiently removed and the loss of valuable substances is extremely reduced in the reactant gas, substantially without causing waste to be disposed. SOLUTION: The objective acryloitrile is produced by allowing propylene and/or propane to react with ammonia and oxygen, preferably in a fluidized bed reactor. The reaction gas formed in this process is brought into contact with a catalyst containing 0.01-20wt.% of ruthenium [containing at least one selected from titania, magnesia, silica, ceria, zirconia and alumina] at 200-550 deg.C to reduce the unreacting ammonia. As this decomposition of ammonia requires oxygen, the feed rate of the air is adjusted so that the air may include an amount of oxygen sufficient to decompose this ammonia.
