Title: Hot water storage tank
Inventor: TANAKA YOSHIO
IPC: F24H1/18
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To allow hot water of relatively high temperature to flow out entirely which is stored in an upper part in a hot water storage tank and used for an electric water heater or the like. SOLUTION: A baffle member 10 projected toward a ceiling at a central area is mounted at an upper area in the tank 1. The member 10 is set so that a total opening area of a water flow opening 14 of a peripheral edge is larger than a total opening area of a water-flow opening 12 at a center of the member 10. Hot water directed toward a hot water outlet 2 is branched to a flow (A) passing the hole 12 of the center of the member 10 and a flow (B) passing the hole 14 of the peripheral edge of the member 10. The hot water A passing the hole 12 is guided to the outlet 2 as it is, and the hot water B passing the hole 14 of the peripheral edge guides the hot water stored immediately under and near the ceiling and near a periphery of the tank to the outlet 2. As a result, the hot water of a relatively high temperature stored in an upper part of the tank 1 can be sent out without retaining.

Title: Elastic form material for precast concrete floor board and method for executing precast concrete floor board construction
Inventor: DANZUKA MORIO
IPC: E01D101/00
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To easily perform execution and secure safety by integrally laminating a base material composed of an elastic foam body and a reinforcing film layer having a higher sliding property and higher strength than the base material fixed and formed on the surface of the side of precast concrete floor board of the base material. SOLUTION: Base material 38 forming the whole height, a reinforcing film layer 40 laminated and integrated on the surface of the precast PC floor board side and an adhesive layer 42 disposed in the face of a vertical beam are provided. In this case, the base material 38 is made of foaming polyurethane foam and the reinforcing film layer 40 is made of a non- foaming PET film. Next, when the PC floor board previously separately molded and hardened in a factory is set on the vertical beam to be moved, it is moved as it is smoothly slid on the reinforcing film layer 40. At the time, breaking and tearing-off of elastic form material 18 is prevented, in addition, the reinforcing film layer 40 is thin, deformed into a shape following the lower face of the floor board, and adhered to the lower face of the floor board good.  Thereby loop-like reinforcing bars themselves are welded to each other, mortar is placed in a joint part, the adjacent PC floor boards themselves are interconnected and integrated, and a construction period can be shortened.

IPC: H05K3/34
Filed: 1987-12-04
Abstract: PURPOSE:To see that cracks do not occur in a ceramic base substance by arranging the constitution that the major part of a solder material may be replaced with a member which exists inside the solder material and has a thermal expansion coefficient smaller than that of the solder material. CONSTITUTION:The major part of a solder material 4 to solder a lead 3 terminal directly to the terminal 2 of a circuit pattern on the surface of a ceramic base substance 1 is replaced with a member which is put between the lead 2 lower end and the terminal 2 inside the solder material 4 and is smaller in thermal expansion coefficient than the solder material 4 and has the same outside diameter as that of the terminal 2 or a little smaller outside diameter than that outside diameter. Accordingly, when soldered to the terminal 2, the shrinkage stress which acts directly on the ceramic base substance, of the solder material 4 which cools and solidifies at the surface of the ceramic base substance 1 can be sharply weakened. Hereby, it can be soldered without causing cracks in the ceramic base substance 1.

Title: Immobilized lipase and hydrolysis of fat and oil with same lipase
Inventor: TAKAHASHI MAMORU
IPC: C11C1/04
Filed: 1989-11-28
Abstract: PURPOSE:To obtain an immobilized lipase capable of excellently hydrolyzing fats and oils by introducing a hydrophobic group to part of amino group and hydroxyl group of chitosan to form a flock and then adsorbing lipase in the flock. CONSTITUTION:A hydrophobic group such as alkyl group or benzyl group is introduced to part of amino group and hydroxyl group of chitosan, a flock is formed from the chitosan and then lipase is adsorbed on the flock to give an immobilized lipase. Fats and oils can be hydrolyzed by using the lipase. As a method of hydrolyzing the fats and oils, a method of dispersing the immobilized lipase into fats and oils and hydrolyzing the fats and oils or a method of passing fats and oils through a column packed with the immobilized lipase and hydrolyzing the fats and oils may be cited. Since the immobilized lipase is different from gel and consists of the flock having both a hydrophilic group and a hydrophilic group, both fats and oils and water can be simply permeated into the immobilized lipase.

Abstract: PURPOSE:To know the current position of a conveyance vehicle in traveling motion and to plan the travel schedule of other conveyance vehicles by measuring time differences between received signals outputted by receivers, installed at respective positions in a conveyance range, as the unmanned conveyance vehicle travels. CONSTITUTION:An unmanned conveyance vehicle 1a sends a pulse signal from a transmitter 7a at constant intervals. The pulse signal is received by the receivers 8a-8c, which report the reception times to a coordinate computer 9. The coordinate computer 9 calculates the position of the unmanned conveyance vehicle from the differences between the times reported by the receivers 8a 8c. Then the result is reported to a controller 2 for the unmanned conveyance vehicle to calculate the current position of the unmanned conveyance vehicle. The transmitter 7a is powered by a dedicated battery 10 and continues to operate even if the unmanned conveyance vehicle stops or if its main body battery comes down. It is therefore decided whether or not other unmanned conveyance vehicles can travel in safety.
