Inventor: OBARA HIROKI
IPC: F24H1/10
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: Not to prevent the increase of a pressure due to operation of a super- atmospheric pressure relief valve but to prevent the increase of a pressure through control of heat insulation combustion. SOLUTION: This water heater comprises at least an incoming water line 1; an outgoing hot water line 2; a heat-exchanger 4; a burner 5; and a heat- exchanger temperature sensor 12 to detect a hot water temperature in the heat-exchanger 4, and in addition to ordinary hot water supply operation, heat insulation operation is practicable.  In the water heater with a heat insulation function, a controller 13 is provided to effect control such that when, during heat insulation operation, an incoming water temperature is higher than a specified temperature, heat insulation combustion is performed until temperature in a heat-exchanger reaches a given set heat insulation temperature, and meanwhile, when an incoming water temperature is lower than a specified temperature, heat insulation combustion is not effected until temperature in the heat- exchanger reaches the given set heat insulation temperature, and at a point of time when temperature in the heat-exchanger is increased to a specified value, heat insulation combustion is stopped.

Title: Guide system for automatically guided behicle
Inventor: ALOFS CORNELL W
IPC: G05D1/02
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To provide an improved guide system for guiding an automatically guided vehicle(AGV) along a passage. SOLUTION: In an almost straight part of a passage, an AGV 40 is guided by the guide system having rails and these rails are arranged as rail segments 10, 12 to 14 mutually in a non-adjacent state. Among respective rail segments 10, 12 to 14, the AGV 40 is guided by a non-rail guide system between the exit terminal 24 of one rail segment 10 and the entrance terminal 20 of the other rail segment. The guide of the AGV 40 by these rail segments attains high speed traveling and the non-rail guide system makes it unnecessary to use a rail switch for switching the AGV 40 from one rail to the other rail, so that a simpler and more efficient guide system is obtained.

Title: Alkaline cell
Inventor: SHIRAI IWAO
IPC: H01M4/06
Filed: 1982-04-12
Abstract: PURPOSE:To obtain an alkaline cell hardly suffering from deterioration due to storage and excellent in preservation property by limitting inner diameter of the positive pole while employing the positive pole pedestal made of a steel plate having thickness of 0.05-0.2m/m. CONSTITUTION:The relation among the inner diameter (a) of a horizontal part of the positive pole pedestal 1, the inner diameter (b) of the horizontal tip part of a sealing ring 4 and the inner diameter (c) of a horsehoe-shaped turning back point of the negative pole sealing plate 6 is defined to be b<a<c, while the material thereof is selected. When considering the strength and workability, of the positive pole pedestal, the steel plate is the best material. In the case of a>b, reaction of an alkaline solution reduces remarkably and there is no generation of voltage failure. The suitable thickness of said positive pole pedestal is 0.05-0.2m/m. That is to say, when being thinner than 0.05m/m, strength of the pedestal becomes insufficient to stand the pressure occurring at the time of sealing process, thus generating its deformation.

Title: Production of refined rice wine utilizing low-protein rice
Inventor: MOGI KAZUO
IPC: C12G3/02
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain effect similar to that lowering yield of polished rice and remarkably reduce production cost while retaining quality of refined rice wine equivalent to that of conventional rice wine by using low-protein rice as rice in fermentation step of unrefined sake. SOLUTION: A low-protein polished rice is adopted as rice used for fermentation step of unrefined sake. Since low-protein rice comes short of mineral, vitamin, etc., because of using a large amount of water when treated, fermentation auxiliary such as calcium acidic phosphate is preferably mixed in fermentation step of unrefined sake. Since dissolution of low-protein rice into unrefined sake is fast and viscosity of unrefined sake becomes high to suppress fermentation of yeast, it is preferable to increase ratio of water used in fermentation step of unrefined sake and acid saccharogenic amylase such as glucoamylase. Fermentation blend is preferably carried out at a ratio of 160 L water for fermentation, 5-15 g fermentation auxiliary and <=100 g saccharogenic amylase to 100 kg rice.

Abstract: PURPOSE:To exactly judge the occurrence and degree of the liquefying of the sandy ground by applying a vibration to an oscillating plate in a square ground formed by two mutually facing side plates or by side ditches in two rows and two oscillating plates. CONSTITUTION:When an oscillator 4 is actuated, horizontal actions are repeatedly given through an oscillating beam 3 to oscillating plates 2, the oscillating plates 2 undergo a vibrating displacement at a pin connecting portion 6 as the supporting point under the ground, and the ground A to be judged undergoes a shear deformation. Also, the void water pressure among soil and sand goes up abruptly, excessive void water pressures are generated, and the ground A is liquefied. In this case, the variations in the aimplitude and frequency of vibration given are read out by a void water pressure guage 16 and a seismometer (accelero meter) 17 buried under the ground A and the rise and variations of void water pressures as well as excessive void water pressures are also read out likewise. By this, the occurrence and degree of the liquefying of the ground A can be judged.
