Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To increase the bobbin winding capacity of a bobbin thread wound round a bobbin to reduce the stop of sewing operation for replacing the bobbin so as to improve the efficiency of sewing operation by passing the bobbin thread wound round the bobbin through a bobbin thread passing hole of a bobbin locking piece to be guided to a looper thread tension spring. SOLUTION: A bobbin 35 is stored in a rotating hook bobbin case holder 31 in the state of being floated from the peripheral wall 33, and a looper thread tension spring 37 is provided in the rising course of a bobbin thread 36 in such a manner that the pressing force to the bobbin thread 36 can be adjusted by a fixing vis 38 and a spring adjusting vis 39. The bobbin 35 is provided with flanges 49a, 49b respectively formed on both end parts in the axial direction of a hollow winding drum 48, and the bobbin 35 is held in the rotating shuttle bobbin case holder 31 by a bobbin locking piece 42, whereby the need of a bobbin case as that in the prior art can be eliminated so that the diameter of the bobbin 35 is increased for the thickness of the peripheral wall of the bobbin case so as to increase the winding amount of the bobbin thread 36.  Thus, it is not necessary to stop the sewing operation frequently for replacing the bobbin 35 during sewing.

Filed: 1980-03-05
Abstract: PURPOSE:To obtain a distilled water and a hot water for room heating by utilizing for the heat source of a heat exchanger a steam generated through a flash evaporation of a geothermal hot water while being fluidized in a multistage flash equipment. CONSTITUTION:As a flash equipment 1, a plurality of flash chambers 3A-3F are formed and orifices 5A-5F are provided on the outer wall 14 and the partition 2 thereof. A geothermal hot water passes through the flash chambers 3A-3F from the orifices 5A-5F sequentially and evaporated by a flash evaporation with a difference in the pressure. For example, after the removal of fine drops with a demister 6B, the steam 30 generated in the second stage flash chamber 3B undergoes a heat exchange with a river water 12 by means of a heat exchanger 11B and the condensed water is collected to a receptacle 7B as a distilled water 10. The river water 12 heated by the heat exchange is released from an upper nozzle 20 of a deaerator 17 and directly brought into contact with the steam generated in the first stage flash chamber 3A and after the oxygen dissolved is dissipated into the air, is transported for room heating with a hot water feeding pipe 19.

IPC: B07B15/00
Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To obtain reutilizable crushed stones within regulated sizes from waste concrete materials. SOLUTION: Relatively large lumps are cracked. Reinforcing bars, wooden chips, foamed styrol, etc., are removed therefrom. The cracked lumps are then passed through a vibrating machine and sand and soil are removed therefrom. The crushed lumps are charged into a large-sized water tank where the wooden chips, foamed styrol, etc., floating on the water surface are removed. The large-sized concrete lumps among the crushed lumps taken out of this water tank are further crushed and reinforcing bar scrap are removed. The lumps are then crushed by a crusher to the cobble stone or small stone form smaller than the prescribed sizes, by which half-finished products are obtd. The reinforcing bar scrap exposed by the formation of these half-finished products is automatically removed by large-sized magnets while the scrap is transported by a conveyor.  The half-finished products from which the remaining reinforcing bar scrap are removed are processed by a sieving type sorter, by which the lumps of the sizes larger than the prescribed sizes are removed and the crushed stones (products) within the regulated sizes are obtd.

Title: Zirconia spherical particle and production thereof
Inventor: OSAKA SHIGEMI
IPC: B01J2/08
Filed: 1990-02-09
Abstract: PURPOSE:To obtain the subject zirconia spherical particles excellent in monodispersion properties with economical advantage by hydrolyzing a reaction product between ammonium zirconyl carbonate and a chelating agent and growing the resultant zirconia sol particles. CONSTITUTION:Ammonium zirconyl carbonate is reacted with a chelating agent (e.g. an oxyacid such as citric acid or a beta-diketone such as acetylacetone) and the resultant product is hydrolyzed to prepare a zirconia sol. The obtained zirconia sol is mixed with a water-insoluble (sparlingly soluble) organic solvent in the presence of a surfactant to form a W/O type emulsion. By heating the resultant emulsion for azeotropic distillation, water in the spherical sol is removed to the outside of the system together with the organic solvent and the sol is converted to a gel at the same time. The gel is calcined to remove organic components in the surfactant, thus obtaining the objective zirconia spherical particles having 0.05-50/mum average particle size, 1-1.5 standard deviation thereof and 5-200m<2>/g specific surface area.

IPC: H04N1/413
Filed: 1987-02-09
Abstract: PURPOSE:To improve efficiency at the time of transmitting or storing a data, by discriminating whether a picture element is the one of halftone one or not, selecting either a dither processing or a binarization processing corresponding to the above result, and selecting either the compression or the non-compression of the data corresponding to the content of an original. CONSTITUTION:A digital spatial filter 16 extracts the data of the picture element(remarked picture element) being positioned in the center of a matrix and the data of eight picture elements being positioned in the neighborhood, and outputs them to a halftone discrimination circuit 17. The discrimination circuit 17 discriminates whether the remarked picture element is the picture element of halftone gradation(halftone) other than white or black. A counter 18 counts the number of picture elements of halftone included in one line. A switch S2, when the number of picture elements of halftone included in one line being less than a prescribed reference value, introduces the output of a compression circuit 20 to an interface (l/F) circuit 21, and when it exceeds the reference value, introduces the output of a line buffer 19 to the I/F circuit 21 by bypassing the compression circuit 20.

Title: Motor-driven winding and rewinding camera
Inventor: KITAJIMA TOMOYA
IPC: G03B1/12
Filed: 1982-02-25
Abstract: PURPOSE:To enable perfect automatic winding and rewinding without requiring artificial operation by providing a one-way linking mechanism between the winding shaft and spool, and transmitting rotation of the winding shaft to the spool when winding and cutting off transmission when rewinding. CONSTITUTION:A one-way linking mechanism consisting of a transmission washer 77 linked with a spool shaft by friction, a driven member 81 which is formed in a body with the spool, and one-way claw 84 energized by a weak spring 83 is contained in the inner case of the spool allowing engagement of the transmission piece 77a of the washer 77 and claw 84. When the transmission piece 77a is turned left by rotation of the spool shaft 65, it is engaged with the claw 84 and rotates the member 81, consequently the spool, in the direction of winding. When rewinding, the transmission piece 77a rotates in reverse direction and is contacted by pressing with the back of the claw 84 and swing it in the direction of releasing. Consequently, the spool does not rotate. Thus, fully automatic winding and rewinding can be effected without requiring any artificial operation.
