Title: Dust collecting apparatus in dental or other handiwork
Inventor: HAYASHIGAWA MUNEO
IPC: A61C13/00
Filed: 1987-05-30
Abstract: PURPOSE:To enhance working efficiency, to maintain the health of workers and to prevent the contamination of the working place, by manufacturing a work table having a wide surface and forming suction nets in the front and two places of the work table and further obliquely mounting a transparent plate thereto. CONSTITUTION:At the time of working, a worker, positioned in front of the work table, extends his hands from both sides at the back of a hollow erected part 6 just as if he embraced the erected part 6 and works while viewing an article during its processing through a transparent plate 9 such as a glass plate or a synthetic resin plate. Therefore, dust is scattered toward and sucked into a mesh plate 7 so that the worker, also protected by the transparent plate 9 is prevented from arrival of dust, fine pieces or the like at his face and the breast. The mesh plate 7 has an L-shape cross-section and forms a part of the work table 2 and, therefore, dust or the like can be perfectly sucked by said mesh plate 7. By this constitution, working efficiency is improved and dust can be immediately sucked without floating and the worker can well work without receiving dust trouble. Further, since an adaptor 5 is provided to an air suction port mount cylinder 4 to make it possible to use an air sucking device of every kind, efficiency is well.

Title: Process for converting hydrogen pressure
Inventor: ITO JOTARO
IPC: C01B3/00
Filed: 1985-06-22
Abstract: PURPOSE:To increase the quantity of high pressure H2 to be generated per unit weight of metal by reducing high H2 pressure to intermediate pressure at a point between a H2 liberation stage and H2 occluding stage and elevating the low H2 pressure to intermediate pressure at a point between a H2 occluding stage and a liberating stage. CONSTITUTION:H2 is occluded in a vessel 30, and high pressure H2 is liberated from a vessel 50 and transported to a high pressure H2 source 59. Then,a connecting valve 70 between the vessel 30 and the vessel 50 is opened and a part of the residual high pressure H2 in the vessel 50 is transferred to the vessel 30 to equalize the pressure in the vessel 30 and 50 to an intermediate pressure. The connecting valve 70 is then closed and a metal M in the vessel 30 is heated and a metal M in the vessel 50 is cooled. High pressure H2 is then liberated from the vessel 30, and low pressure H2 is occluded in the metal M in the vessel 30. Then, the valve 70 is opened and residual high pressure H2 in the vessel 30 is transferred to the vessel 50 equalize the pressure of both vessels 30, 50 to an intermediate pressure. Thus, occluded H2 in the vessel 30 is transferred to the vessel 50 and occluded in the vessel 50. The cycles are repeated.

Title: Gear pump
Inventor: INOUE SATORU
IPC: F04C13/00
Filed: 1984-07-02
Abstract: PURPOSE:To prevent a highly viscous deposition from accumulating in the side surface gap of a gear to make it possible to smoothly rotate the gear, by forming thin grooves in the side surface of the gear, which communicate with the peripheral edge section of the gear, being inclined rearward in the rotating direction of the gear and extending from the edge section of the shaft hole of the gear. CONSTITUTION:A gear 20 in a gear pump is formed in its side surface thin grooves 20 communicating with the peripheral edge section of the gear. These thin grooves 20 are formed such that they are inclined rearward in the rotating direction and extending from the shaft hole 12 of the gear. Therefore, before a highly viscous fluid entering into the gap between the gear and the side plate of the gear pump forms a deposition due to affection of shearing force or heat, the fluid is forced to be fed to the tooth tips of the gear. Therefore, the deposition may be prevented from accumulating in the gear side surface gap, and it is possible to smoothly drive the gear pump.

Title: Epdm rubber composition
Inventor: SUZUKI TAKAMASA
IPC: C08L19/00
Filed: 1979-10-25
Abstract: PURPOSE: A rubber composition which can be vulcanized into a bubble-free vulcanizate having improved compression set, prepared by compounding EPDM with both quick lime and a higher saturated fatty acid.  
     CONSTITUTION: One hundred (100)pts.wt. of EPDM is compounded with both 1W 20pts.wt. of quick lime and 2.5W10pts.wt. of a C 710  higher saturated fatty acid. As the quick lime used, one having a particle size of below 150μ is preferred. This compounding is effective to prevent formation of bubbles of water in a vulcanization system under a substantially zero external pressure. The C 710  higher fatty acid (for example stearic acid) is required to be a fatty acid which is low in unsaturated acid content, because unsaturated acids such as oleic acid and linoleic acid prevent vulcanization, lower tensile strength, etc. of vulcanizates and cause oxidative deterioration.
