IPC: A61K35/66
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To improve treatment effects such as to shorten treatment periods in clinical treatments of small animals by the simultaneous administration of effective microorganism drinks and systemic treatment of alternate current magnetic shower in addition to Occidental medical treatments. SOLUTION: There are examples of effective clinical treatment results of small animals; Dogs unable to walk and crawling around due to broken bones, sprains, bruises, and lumber disorder, became able to walk in about a month after being administered with vitamin D, calcium, and effective microorganism drinks, simultaneously with regular systemic treatment with alternate current magnetic shower, fiber times a day, 30 minutes each time. Dogs and cats able to walk only feebly due to malnutrition and aging improved in walking after several days by continuous systemic treatment with alternate current magnetic shower while administering vitamin agents, nutritious food, and effective microorganism drinks. That is, reduction in the healing period is seen in those examples.  In particular, since the effective microorganism drinks have the capability of removing active oxygen much talked of in recent years and of increasing immunity, a great hope may be placed on it for the treatments of diseases which have been considered difficult to heal.

Title: Liquid crystal charging method
Inventor: TSUNODA YUKIYOSHI
IPC: G02F1/1341
Filed: 1990-11-05
Abstract: PURPOSE:To reduce the quantity of liquid crystal stuck to a panel and discharged outward thus improve liquid crystal consumption efficiency by controlling the level of the liquid crystal in a liquid crystal pan for setting a panel so that the liquid crystal is brought into contact with only the part near the inlet port of the panel. CONSTITUTION:A liquid crystal pan 1, 2 liquid crystal bath 9 connected thereto and panel 3 are set in a vacuum device. When the vacuum device is vacuumed to reduce the pressure in the vacuum device down to the specified degree of vacuum, the liquid crystal bath 9 is lifted. When liquid crystal 2 flows into the liquid crystal pan 1, and the liquid level is brought into contact with the inlet port of the panel 3, the flow is stopped. When the pressure in the vacuum device is made to return to the normal pressure, the liquid crystal in the liquid crystal pan 1 is gradually charged in the panel 3 due to the atmospheric pressure through the inlet port. Since, the liquid crystal 2 is always brought into contact with the part near the inlet port only and can not be stuck to the other parts by this constitution, the quantity of the liquid crystal stuck to the panel 3 and discharged to exterior can be reduced and the liquid crystal material consump tion efficiency can be improved.

Title: Illuminating lamp device
Inventor: SHIMADA SHIGEAKI
IPC: F21S2/00
Filed: 1991-10-21
Abstract: PURPOSE:To prevent scatter of broken pieces of a discharge lamp when the lamp is broken by an excessive shock. CONSTITUTION:A box body 3 is blocked by an outer tube 6 and a filter 10, and a discharge lamp 1 is housed in the box body 3. The discharge lamp 1 is screwed up to a socket 5 fixed on the box body 3, and held in the box body 3. At the front side of the front lens 21 (at the lower side in the figure) of the discharge lamp 1, a circular stopper 8 made of a heat-resisting material is provided. Since the inner diameter of the circular stopper 8 is set less than the maximum, diameter of the discharge lamp 1, the front lens 21 is prevented from scattering out of the box body 3 even in case of a drop of the front lens 21 from an outer sleeve main body 20, which is the most possible case of damage. And since the stopper 8 is formed circular, the luminous energy of the radiating light from the discharge lamp 1 is never reduced.

Title: Abnormality detection device for polygon mirror drive device
Inventor: YAMANAKA TOSHIHISA
IPC: G02B26/10
Filed: 1992-11-10
Abstract: PURPOSE:To detect an abnormality in a polygon mirror drive device by recognizing that a lock signal becomes low after a rotation stop is commanded to a polygon mirror. CONSTITUTION:A rotation command or stop command to command rotation or stop of a polygon mirror 2 is outputted from an operation panel 7. In the meanwhile, a lock signal is outputted from a phase control part 5 only in case the polygon mirror 2 is rotating at a specified speed. A CPU 6 recognizes that the phase control part 5 stops outputting the lock signal after the stop command is outputted from the operation panel 7. In the case, the stop of outputting of the lock signal is recognized, it is determined that a polygon mirror drive is actuating normally, while it is determined that any abnormality is generated in the case the lock signal is kept being outputted.

Title: Nestable type rack
Inventor: ITOI IYUU
IPC: B65D21/04
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To obtain nestable type racks that are stable when they are stacked up, are lightweight and excellent in durability. SOLUTION: Racks can be stacked up in tiers when they are used as racks and stowed inside the others having the same construction when they are out of use. The rack has no rail under a loading floor X, and fittings 9 are provided right under front posts instead. There are upper beams 7 right on the front posts so that the upper beams 7 can meet the fittings 9. In the case square pipe upper beams are used instead of the upper beams 7, members to meet the fittings 9 can be attached at the front and rear ends of the square pipe upper beams. Therefore, since the loads on the racks in the upper tiers vertically exert on the posts when the racks are stacked up in tiers, bending stress does not work on the posts. Having no rail, the rack is lightweight.

Abstract: PURPOSE:To reduce an element isolation region and simultaneously prevent generation of damage in a substrate, by performing selective oxidation after forming the offset of an Si3N4 film wherein an SiO thin film is formed for an Si substrate. CONSTITUTION:An SiO2 12, and Si3N4 13 and an SiO2 14 are stacked on a P-type Si substrate 11. A mask is formed, RIE is performed, an SiO2 thin film 15 is arranged, and an Si3N4 thin film 16 and an SiO2 film 17 are deposited. Then a sidewall 17' of SiO2 is formed by RIE, and the Si3N4 16 and the SiO2 15 are eliminated by etching. The SiO2 14 and the sidewall 17' are subjected to wet etching, and an offset 16' of the Si3N4 film is formed. Thus an offset of Si3N4 is formed which has the SiO2 thin film 15 as a buffer layer arround a prearranged element isolation region. After a P-type inversion protection layer 18 is formed by implanting ions, a field oxide film 19 is formed by wet oxidation. By this constitution, the element isolation region can be reduced, and damages do not generate in the substrate.
