Title: Paper refeeding device
Inventor: JIYOUDAI AKIYOSHI
IPC: B65H29/51
Filed: 1989-02-14
Abstract: PURPOSE:To surely detect whether paper exists in a housing part or not by rewinding a belt to an initial position where the paper is started to be housed after a paper refeeding device is turned on by a power source and deciding that the paper is jammed when the paper drawn from the paper housing part is detected by a detection means during the rewinding operation. CONSTITUTION:After the paper refeeding device is turned on by the power source, the belt 240 is rewound until an initial position mark 242 given to the belt 240 is detected by an initial position mark detection means SE4. When the rewinding is finished, all the paper housed in the belt 240 are exhausted. However, when the paper drawn from the housing part 200 is detected by a paper detection means SE3 at this time, the paper is one which is left in the housing part 200 before, that is, when the power source is turned off. Then, it is decided by the detection signal of the paper that the paper is jammed and that effect is displayed outside the device. Thus, the paper left in the housing part 200 by being taken up to the belt 240 because a mode is set inadvertently or paper refeeding operation is forgotten is easily and quickly ejected outside the device.

Abstract: PROBLEM TO BE SOLVED: To efficiently obtain a glass by a sol-gel method, capable of easily preventing the destruction of a gel and carrying out a solvent-exchanging treatment at a high speed to shorten the time required for an immersion process by performing plural immersion treatments of the gel obtained by the sol-gel method in a treating liquid at a specific temperature under a high pressure. SOLUTION: When plural immersion treatments of a gel in a treating liquid are carried out, the gel is treated at a temp. of 50-250 deg.C under a high pressure in at least either one of the immersion treatments. At least two pressure-proof vessels in whose systems temperatures and pressures can independently by controlled are connected to each other, and an immersion liquid in one vessel can be transferred to the other vessel in a state maintained at a high temperature and under a high pressure without returning the temperature and the pressure to original temperature and pressure, respectively.  For example, treatment vessels 4, 9 at high temperatures and at high pressures are disposed in the A and B chambers 3, 8, respectively, of a pressure-proof vessel 1 provided with a partition 2, and the A and B chambers 3, 8 are maintained at prescribed temperatures and at prescribed pressures with heating means 6, 10 and valves 7, 11. A gel 5 is immersed in a vessel 4 and subsequently transferred to the vessel 9 through the partition 2. Thereby, the glass is rapidly obtained in a high yield without destructing the gel 4.

IPC: H01L21/8238
Filed: 1993-02-25
Abstract: PURPOSE: To lessen a level difference between a memory region and a peripheral part, by a method wherein a well region forming process where a memory cell is formed is carried out before a well region forming process where the peripheral part is formed is carried out. CONSTITUTION: An oxide film 22 and a nitride film 23 are successively formed on a semiconductor substrate 21, a part where a P well region is not formed is covered with a photoresist 24, and P-type impurities are ion-implanted so as to form a P well first. Then, a thick oxide film 25 is formed on the P well region, the nitride film 23 is removed off, and N-type impurities are ion- implanted into a region where an N well is formed, using the thick oxide film as a mask. An N well 31 and a P well 32 are formed through a drive-in process, and then the oxide films 22 and 25 are removed off, whereby the P well region 32 is set lower than the N well region 31 in level. Therefore, even if a capacitor is formed on a P well region in an after process, a level difference between a memory region and a peripheral part can be lessened as a whole, because the P well region is lower than an N well region where a peripheral circuit is formed.

Title: Igniter of rocket and the like
Inventor: ENDOU TAKAO
IPC: C06C7/00
Filed: 1979-03-28
Abstract: PURPOSE: To improve the ignition performance of an igniter by a method wherein nozzle pores are sealed to keep space inside a case approximately at an atmospheric pressure by sticking a film of a material which can be destroyed by fire onto a portion of a case in which many nozzle pores are dispered.  
     CONSTITUTION: When a squib 13 is ignited by an electric current from an outside power supply, an initial charged powder 12 is ignited to produce fire, which breaks a cap 15 and passes through a fire passage 17 to blow out to a sub charging chamber 7 to igmite a sub charged powder 8. The fire of this sub charged powder 8 blows out through a through-hole 10 to a main charging chamber 5 to ignite a main charged pellet 4, of which fire breaks a film 3 at a nozzle pore 2 by its thermal and pressure shocks and blows out from the nozzle pore 2 to ignite the ignition surface of a propelling powder. In this method an igniting transition time of the sub charged powder 8 can be stabilized as in the ground since all inside areas in a case 1 have been kept approximately at an atmospheric pressure by the film 3 even though an atmosphere outside the case 1 is vacuum.
