IPC: F24C7/02
Filed: 1987-09-08
Abstract: PURPOSE:To automatically compensate the difference in the preheating temperature when the preheating is performed with one power source frequency by adding the temperature compensation memorized in a computer to the set temperature of a thermistor so that the heating may be performed at the same preheating temperature for different power source frequencies. CONSTITUTION:When a preheating cooking is to be performed under conditions where the power source frequency is as high as 60Hz and the speed of a hot air fan 11 is as low as 2,000rpm, the temperature setting of a thermistor 9 is made (200+10) deg.C which is 10 deg.C higher than that which is appropriate for 50Hz. Said temperature setting is memorized in a computer 3 as compensation temperature, and then the heating can be performed at 200 deg.C, which is same for a lower power source frequency of 50Hz, and the preheating will be completed in 7 minutes 30 seconds. Therefore, the difference in the preheating temperature caused by different power source frequencies of 50Hz and 60Hz can be automatically compensated by identifying the power source frequency by the computer 3.

Title: Production of brewed vinegar by fermenting garlic
Inventor: SATO MIKIO
IPC: A23L27/24
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To obtain a brewed vinegar of garlic by a fermentation using yeast, having a garlic feeling not to make a person anxious about it, not greening, having a good flavor since a vinegar obtained by immersing garlic in vinegar has a sharp garlic smell, greens by reaction with vinegar and reduces a commercial value by permeation of the greening into vinegar. SOLUTION: Garlic heated by steam is made into a paste, supplemented with a saccharide or mixed with an alcohol and the saccharide and further with yeast. A garlic wine is brewed and subjected to acetic acid fermentation to produce a garlic vinegar. Garlic forms a sharp pungent odor and sterilizing (bacteriostatic) action by the destruction of cell, fermentation of garlic has been difficult due to its strong sterilizing action but garlic can be readily fermented after steaming and making it into a paste and acetic acid fermentation has the same result as that of original acetic acid fermentation.

Title: Production of cement
Inventor: ASAKURA ETSURO
IPC: C04B7/52
Filed: 1990-08-29
Abstract: PURPOSE:To obtain cement providing high-fluidity concrete by sprinkling a specified amt. of an aq. sulfate soln. over the cement when clinker is crushed into cement and/or when cement is transported to a storage tank. CONSTITUTION:An aq. soln. contg. 0.02-1 pts.wt. sulfate as SO4 is sprinkled over 100 pts.wt. of cement when clinker is crushed into cement and/or when the cement is transported to a storage tank and mixed. A relatively inexpensivive sulfate having high solubility, e.g. MgSO4, FeSO4 and Na2SO4, is appropriately used as the sulfate. The concrete obtained by mixing this cement has higher fluidity than the concrete using conventional cement. Since the amts. of water and water reducing agent to be used can be reduced to obtain the same fluidity as the concrete using conventional cement, the strength developing property of the concrete is improved, and the production cost is reduced.

Title: Optical fiber gyroscope
Inventor: IWASHITA SHIGEKI
IPC: G01C19/72
Filed: 1990-08-27
Abstract: PURPOSE:To keep a quantity of light constant as passing through a polarizer by converting all optical paths containing a polarizer and a depolarizer to an optical fiber to add another depolarizer in a single-mode optical fiber from a light emitting element to the polarizer. CONSTITUTION:A light emitting element 1 is a light source which emits a monochromatic light and employs a laser diode or the like with a coherent length shorter. Besides a depolarizer 3 normally provided, a depolarizer 2 is disposed in the course of a first fiber optical path 11 of a single mode optical fiber for connecting the light emitting element 1 and a fiber type polarizer 9. Then, light emitted from the light emitting element 1 is a linearly polarized light, depolarized with the depolarizer 2 and reaches the polarizer 9, where it is turned to a linearly polarized light in a certain direction. As the light is depolarized once, an amplitude of the light when turned to the linearly polarized light with the polarizer 9 is constant irrelevant to a bearing of the light emitting element. This eliminates the need for adjusting axes between the light emitting element 1 and the polarizer 9 and there is no effect on the light as the light is depolarized even when a polarization plane is rotated in an optical fiber as caused by external forces and temperatures.
