Abstract: PROBLEM TO BE SOLVED: To prevent the extinguishant from being scattered around other parts than a range, and to prevent a floor of a kitchen from being polluted with the extinguishant by providing an extinguishant ejecting means to release the locked condition of a refractory expandable body and expand it with the ejection of the extinguishant on an extinguishant ejecting device. SOLUTION: In a range hood 11 having a fire extinguisher furnished with an extinguishant scattering preventive device, when a fire occurs from a range 13, the extinguishant in which the inner agent and the outer agent are mixed, is ejected toward the range 13 from a nozzle in a lid body of an extinguishant ejection device 18. The extinguishant is ejected from an ejection pipe 35 as soon as the extinguishant is ejected, and the extinguishant presses a reception part 37 of a refractory expandable body 36, a Magnet is detached from a lower end 11a of the range hood 11, and the refractory expendable body 36 is immediately expanded by the weight of a weight. The range 13 at the position where a fire occurs, is covered with the expanded refractory expandable body 36, and the ejected extinguishant is not scattered over the periphery other than the range 13.

Abstract: PURPOSE: To secure the facilitated formation of the micropattern as well as to ensure the high-precision working for the minute measurements by improving the diffusing process of the impurity to the selective region of the semiconductor device.  
     CONSTITUTION: Silicon oxide film 2 is formed on the surface of silicon wafer 1, and silicon glass BSG film 3 containing the boron is formed on the surface of film 2 to be turned to BSG film 3 featuring a fixed pattern through the photo resist technique. Then poly-crystal silicon film 4 of a fixed thickness is formed, and furthermore the heat treatment is given to form poly-crystal film 4a containing the boron from film 3. Film 4 containing no boron is removed with use of the etching solution containing pyrocatechol and ethylenediamine to make the part of film 4a remain. Then film 3 is used as the boron source of the impurity as well as the foundation of the fixed pattern of the insulator in case film 4a is diffused selectively.

Abstract: PURPOSE: To control gas-liquid contact capacity quickly and easily by circulating absorbing liquid between a gas-liquid contact tank and a receiving tank through an overflow part and changing the flow rate of the circulating liquid thereby moving  the head of the overflow part upward tne downward quickly.  
     CONSTITUTION: A controller E 1  for continuous type gas-liquid contact capacity is disposed with a receiving tank 3 contg. the absorbing liquid 2 overflowed to the side of a  gas-liquid contact tank 1 provided with an overflow part 1a on the side wall. This  tank 3 is coupled to the tank 1 by means of a pipe 5 via a pump 4. The introduced  gas A supplied through a supply port 1b is passed through the spaces of respective gas- liquid contact cylinders 5 to bubble the inside of liquid 2 and is discharged to the outside of the tank. On the other hand, a weir 7 having an opening part 7a with the  upper part narrowed is mounted at the part 1a. Hence, the liquid flow to be returned  to the tank 1 is increased or decreased with a control valve 8 in the process of circulating the liquid 2 between the tank 1 and the tank 3, whereby the overflow head ha of  the part 1a is changed largely. The head H of the tank 1 is moved upward and downward quickly, whereby the depth (h) of the gas-liquid contact liquid, that is, gas-liquid  contact capacity, is controlled (increased or decreased) quickly and easily.

Title: Non-volatile semiconductor memory device
Inventor: ITO YASUO
IPC: G11C16/02
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To improve reliability for write protection in a non-selective NAND train by applying a voltage which is sufficiently capable of ON state even in a normally OFF state and selective automatic boost of the channel potential on the control gate of each of the selected memory cells, the neighboring memories, and the memory cells sharing a control gate. SOLUTION: The control gates of memory cells selected ones with a circular mark, the neighboring one and the other ones are impressed with 20V, 4.5V and 11V. With this voltage control, the selected transistor SG 1 is made OFF by 3.3V supplied from a non-selective bit line BL2 to generate automatic boost. Accordingly the potential of the control gate of the memory cell impressed with 4.5V becomes lower than the channel potential and made OFF to provide a write operation. The potentials of the channel regions 2, 1 and 3 of the memory cells are raised to 10V, 7V in response to the rise of the voltage from 0V to 20V, and from 0V to 11V, diminishing the potential difference. Therefore, stress applied to memory cells are mitigated, improving reliability.

IPC: B29C45/78
Filed: 1992-03-05
Abstract: PURPOSE:To prevent the generation of defects by setting shape models of a molded product and cooling pipe models of a plurality of systems of a molding die for manufacturing the molded product in a manner of forming a positioning relation in the molding die and simulating the temperature distribution of shape models of the molded product using the cooling water flow rate as a parameter. CONSTITUTION:Simulation analysis is performed by using the set cooling water flow rate, and the temperature distribution of shape models 1a and 1b of a molded product is computed after the given time is passed. Then, a site P where said temperature distribution comes up to the maximum temperature and the temperature and the minimum temperature are found. The temperature difference between said maximum and minimum temperatures is computed and whether the difference value computed is within the allowable value or not is determined. In the case the difference is not within the allowable value, only the cooling water flow rate data of a system 25 of a cooling pipe 2 in the position closest to the site of maximum temperature out of the flow rate data used in the analysis is changed into the data in which the given flow rate only is increased. The processes are repeated until a value within the allowable value is obtained. Manufacturing can be started just after building up a molding line by said arrangement.
