Title: Obstacle detecting device for unmanned transport vehicle
Inventor: OKANO KIMIHIKO
IPC: B60T7/22
Filed: 1989-03-30
Abstract: PURPOSE:To vary the detection range for an obstacle and reduce the dimension of a transport vehicle itself by installing a detection arm in which the installation angle for a car body can be adjusted and a means for detecting the contact with an obstacle on the basis of the shift of the detecting arm, onto the outer surface of a car body. CONSTITUTION:A front obstacle detector 5 is installed onto the front surface of a car body 1, and each side obstacle detector 7 is installed at the angle thetacorresponding to the car width of a trailer 2a for traction onto the right and left side surfaces of a car body 1. In a side obstacle detector 7, if a detection arm 15 is applied with an external force in a prescribed direction, a projection 17 turns in a prescribed direction around a shaft 12 against a spring 21, and separates from a contact point 25a. Therefore, a limit switch 25 is turned OFF, and the contact with an obstacle is detected. While, as for the front obstacle detector 5, if an external obstacle contacts a bumper 36, a link mechanism 35 is bent, and absorbs the impact, and a limit switch which is not shown on the figure detects the contact similarly in the above-described.

Title: Apparatus for producing steel ingot
Inventor: TAZOE NOBUHIRO
IPC: B22D11/128
Filed: 1985-04-15
Abstract: PURPOSE:To form an ingot having no central segregation and center porosity by disposing a light rolling down device on a moving line for the ingot and providing further a press device which forces the ingot after solidification in the thickness direction on the down stream thereof. CONSTITUTION:The ingot P is derived downward from a mold 1 of a continuous casting machine and starts solidifying internally just before the place where the light rolling down device 3 is installed. The light draft is exerted to the ingot by the device 3 to decrease the thickness of the ingot P by as much as the shrinkage no solidification during the time since the ingot starts internal solidification until the entire part solidifies. The ingot P right after the solidification is thereafter forged in the thickness direction by the press device 4, by which the center porosity is annihilated.

Title: Production of trioxane
Inventor: HAMANAKA KATSUHIKO
IPC: C07D323/06
Filed: 1982-05-12
Abstract: PURPOSE:In the production of trioxane by condensation of formaldehyde, the formaldehyde is fed in the form of a gas substantially free from water and further, the aqueous phase remaining after recovery of trioxane by extraction is refluxed to the reaction zone, thus giving trioxane advantageously. CONSTITUTION:Gaseous formaldehyde substantially free from water is fed as a raw material 1 to the reaction zone 2 where aqueous formaldehyde is evaporated in the presence of an acidic catalyst by heating and the evaporated vapor is introduced into the distillation zone 3. Then, the distillate from the distillation zone, containing trioxane is brought into contact with an organic solvent 4 which is a zeotropic with water and insoluble in water, preferably an aromtic hydrocarbon, especially benzene. Then, the resultant mixture is separated into the organic solvent phase containing trioxane and the aqueous phase 6 and trioxane is recovered from the former phase, while the latter phase is made to reflux to the reaction zone 2. Thus, trioxane used as a raw material for polyoxymethylene is obtained in high purity and high yield through a simplified process.

Title: Breeding shed for warm-blooded animal
Inventor: HAWAADO DEII KUUZAA
IPC: F24F7/06
Filed: 1988-03-31
Abstract: PURPOSE: To enable fresh air to flow in a room without stagnating therein, by providing ventilation means for exhausting indoor air to produce negative pressure in rooms so as to introduce fresh air thereinto and further exhaust the indoor air. CONSTITUTION: In a breeding hut for warm-blooded animals, when a difference between indoor and outdoor temperatures is small, it is possible to exhaust air from rooms 7 and 8 via air ports 56 to generate negative pressure in the rooms, thereby introducing fresh air into the rooms via ventilation openings 26. Also, when the temperature difference is large, it is possible to generate positive pressure in the rooms by reversely operating the ventilation means, thereby restricting the vertical downward flow of fresh air. In this case, the indoor air introduced from the outside via the air ports 56 generates positive pressure in the rooms, thereby exhausting indoor air via the ventilation openings 26.  In both cases of generating negative and positive pressures in the rooms, fresh air flowing toward a floor 11 is deflected by the floor 11 to flow toward side walls 2 and 5, thereby deflecting to flow upward.

Title: Method for high-frequency vacuum thawing
Inventor: TAKAHASHI MITSUHIRO
IPC: A23B4/07
Filed: 1994-04-19
Abstract: PURPOSE:To provide a high-frequency thawing method for commercial use effective for completely eliminating the partial over-heating caused by the irradiation of high-frequency radiation and free from the discoloration and the deterioration of taste even after the preservation in a refrigerator (for 2-3 days) as well as after thawing. CONSTITUTION:An ice layer is formed on the whole surface of a thawing object such as fish and livestock meat cut to a single meat block (including a composite block prepared by bonding meat pieces) and the thawing object is thawed by intermittently radiating high-frequency radiation under an evacuated condition corresponding to the boiling point of 10-30 deg.C. The ice layer suppresses the temperature increase at the surface of the meat block to prevent the partial over- heating. The contact of the thawing object with air is shielded by maintaining the ice layer after thawing as well as in thawing to prevent the oxidation, the deterioration and the contamination and proliferation of microorganisms in air. The thawed product can be preserved in a refrigerator for 2-3 days without causing the discoloration and the deterioration of the taste, etc., of the meat.
