Title: Temperature limiting device
Inventor: INADA HITOMI
IPC: G05D23/02
Filed: 1988-03-29
Abstract: PURPOSE:To simplify the structure and to reduce the weight by supporting a shape memory alloy in a part of a device and covering or opening the surface of the device in accordance with the variance of temperature to adjust heat exchange. CONSTITUTION:A heat radiation plate 2 is attached to a part of a device 1 as one body, and a heater 3 is arranged in the plate 2. One end of a shape memory alloy 4 is fixed to one end part of the heat radiation plate 2 by a screw 5. This alloy 4 is so deformed that it is folded and contracted like a folding screen at a temperature higher than the held temperature of the device 1 and is expanded along the upper side of the heat radiation plate 2 at a temperature lower than said held temperature. The surface of the shape memory alloy 4 is subjected to surface treatment like plating for the purpose of raising the reflectivity. Thus, the shape memory alloy 4 adjusts heat exchange to outside air in accordance with the variance of temperature to hold and limit the temperature of the device.

Title: Bellows rubber hose and preparation thereof
Inventor: HOSHIJIMA HIROYUKI
IPC: B29C48/32
Filed: 1983-04-27
Abstract: PURPOSE:To make it possible to efficiently prepare a bellows rubber hose having no parting line to the outer peripheral surface thereof, by externally inlaying a rubber hose to the outer periphery of a mandrel which has a bellows shaped hollow part and has a large number of comminucation orifices formed to the outer periphery thereof while making the internal pressure of the hollow part lower than external pressure under a vulcanization condition. CONSTITUTION:After an unvulcanized rubber hose 2 having a real cylindrical shape is fitted around a mandrel 6, both ends of the hose 12 are sealed. In the next step, the whole is received in a vulcanization boiler to be heated to a predetermined temp. and, at the same time, the atmospheric pressure in the hollow part 7 of the mandrel 6 is made lower than that of the outside. When the internal atmospheric pressure of the hollow part 7 is made lower than that of the outside, the atmospheric pressure between the hose 12 and the mandrel 6 is lowered through the orifices 11 of the mandrel and the hose 12 is molded along the bellows part 10 of the mandrel 6 by pressure difference and plasticized and stabilized by a vulcanization condition. In the next step, when air is introduced into the molded bellows rubber hose 14 from a plug 8 after vulcanization, the hose 14 is inflated and, therefore, if bands 13, 13 are loosen to draw the hose 14 to one direction, the hose 14 is easily detached. By this method, a rubber hose having no parting line can be prepared.

Abstract: PURPOSE:To provide a decarburization-treating method of decarburizing chromium-containing molten steel in reduced pressure, by which the oxidation of chromium in the molten steel is restrained and the decarburization is efficiently executed in high speed. CONSTITUTION:In the refining method of chromium-containing molten steel executing the decarburization in the vacuum after decarburizing in the atmospheric pressure in the same refining vessel, the decarburization in the vacuum is started in the condition of <=0.5mass% [C] concn. and <=30mass% (Cr2O3) concn. in slag and the pressure is reduced to <=200Torr vacuum degree. By using gaseous oxygen or mixed gas of the gaseous oxygen and inert gas as the blowing gas, until the [C[ concn. becomes 0.1mass%, the refining is executed, and after the [C[ concn. lowers to this value or further lower, the refining is executed with only the inert gas. By this method, the oxygen efficiency for decarburization is improved and the decarburizing speed is improved at the same oxygen supplying rate, and the unit consumption of Si for reduction after decarburizing can be reduced, and also as the refining time can be shortened, the productivity is improved.

Title: Variable gain circuit
Inventor: FUJII TOSHIKAZU
IPC: H03G3/10
Filed: 1987-03-30
Abstract: PURPOSE:To obtain a gain circuit with low noise and a low distortion factor, by providing a means which varies a circuit bias current automatically corresponding to the level of an input signal in addition to a variable gain function part. CONSTITUTION:The input signal of an input terminal 11 is supplied to a transistor(Tr)13 via a resistor 12, and also is supplied to a voltage-current converter 33. A voltage applied on the terminal 11 is converted to a current by the converter 33, and full wave rectification is applied at a full wave rectifier circuit 32. A rectified output is mixed with the output current of a constant current source 31, and its output current is distributed to Trs 13, 14, 18 and 19, and a current mirror circuit 34 by a current distributor 28. In such constitution, since the output current of the circuit 32 is decreased when a signal level is low, and thereby, the output current of an adder 30 is decreased, and the output current of the distributor 28 is also decreased, the noise of the circuit is decreased, and an S/N can be improved. Also, when the input signal applied on the terminal 11 is large, the output currents of the circuit 32, the adder 30, and the circuit 28 are also increased, and the dynamic range is increased, thereby, distortion can be reduced.

Title: Animal control device by combination of neck ring and nose ring
Inventor: ROBAATO KEE ANDAASON
IPC: B68B1/02
Filed: 1986-04-04
Abstract: A combination collar and muzzle (10) is used as a humane method of restraining, controlling, and achieving obedient behavior of animals, dogs in particular. A collar member or loop (12) encircles the neck immediately behind the ears, and a second loop (13) encircles the upper and lower jaws of the animal to form a type of a figure eight combination collar and muzzle. The two loops (12, 13) are coupled together with a ring (15) behind the jaw. The loops (12, 13) are slidably connected so that when a leash (26) is attached to the portion of the muzzle loop (13) extending out from the connecting ring it will slide easily and at the same time will exert a downward pressure on the neck immediately behind the ears. Pressure is thus simultaneously applied to nerves and muscles tending to control the dog humanely and without choking or applying pressure to the trachea and larynx. The simultaneous pressure serves to calm and control the dog in a precise and effective manner without injury or choking and achieves precise, active and effective control and calmness without injuring the dog.
