Title: Connecting mechanism of sleeve and feed path in hot- chamber type die-casting machine
Inventor: NAKANO AKIO
IPC: B22D17/20
Filed: 1979-09-27
Abstract: PURPOSE:To prevent the leakage of molten metal of high-pressures by making the feed path narrower as it goes closer to the end from the root part and peripherally contacting the mouth edge of a sleeve with the inlet at its end through linear contacting. CONSTITUTION:In a hot-chamber type die-casting machine consisting in interposing an injection device 4 in a melting furnace 3, placing the pressurizing chamber 4a provided in the lower part thereof under the molten metal surface of the melting furnace and connecting the same to dies 5 with a feed path 6, the member 6a forming the inlet of the feed path 6 is formed into a projecting shape of which the cross sectional area decreases as it goes toward the end from the root part. The inlet of the feed path 6 is opened at the end thereof and the cross sectional shape of the intermediate part of the member 6a is matched to the outlet shape of the bottom end of the sleeve 4b forming the pressurizing chamber 4a. Thence, the bottom end of the sleeve 4b is pressure contacted with the inlet of the feed path 6 through linear contacting and is thereby watertightly connected therewith. Because of this, the leakage of the high-pressure molten metal 2 is prevented.

IPC: G03B27/52
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To attain quick processing and to print both of a sub-image and a main image with excellent finish quality by simple constitution. SOLUTION: By a lens for printing a sub-image 52 arranged on the optical axis L2 of a sub-exposure light source 42 and between a liquid crystal panel 46 and a photographic paper 14, the sub-image displayed on the panel 46 is formed on the paper 14 as the image of 1/2 area. Thus, since the resolution of the printed sub-image becomes high with respect to the display ability of the panel 46 by depending on reduced magnification, the image with the high resolution is printed on the paper 14. Besides, since the printing processing of the sub-image can be executed in an almost identical exposure time to that of the main image by adjusting the light quantity of the light source 42, the large amount of processing is realized in a short time.

Title: Filter medium
Inventor: HAYASHI YOSHIHARU
IPC: B01D39/16
Filed: 1978-10-12
Abstract: PURPOSE:Filter medium which can easily remove dust deposited on the surface, and which is formed by sticking mesh on the surface of foamed polyurethane sheet. CONSTITUTION:Filter medium is formed by sticking mesh 2 on the surface of foamed polyurethane sheet 1 with an adhesive. The mesh 2 is woven, for example, from nylon filament. When the mesh 2 consists of, for example, 40 mesh, 400 denier fiber is used to make plain weave. When the mesh 2 consists of 80 mesh, 150 denier fiber is used to make plain weave. When this filter medium is used in a filtering apparatus, dust is deposited within the meshes in the form of bridge. Hence, the amount of dust which adheres directly to the surface of the sheet 1, is small and the dust and dirt can be removed rapidly by known methods.

Title: Engine ignition timing controlling apparatus
Inventor: FUJIMOTO TAKANORI
IPC: F02P5/155
Filed: 1980-09-10
Abstract: PURPOSE:To obtain the ignition timing characteristic with the advanced angle having a prescribed inclination by advancing the position where the first output of an integrator reaches the second standard value, namely the position where trigger signal is generated, to the prescribed cank position side, as the number of revolution of an engine increases. CONSTITUTION:The crank angle alpha from the prescribed crank position T1 where angular signal is generated to the position where the discharge voltage of the output voltage reaches the standard voltage V2 is shown in alpha=beta-6N (V2.Capacity of condenser 13/I2), with the number N of revolution of an engine, angle beta in discharge range, standard voltage V2, and discharge current I2. As beta is constant independently of the number of revolution, if the standard voltage V2 and the capacity of the condenser 13 are constant, the crank angle alpha is determined as the funtion of only the number N of revolution and reduces proportionally with the rise of the number of revolution. Therefore, the starting-up timing of the output voltage E of a comparator 16 advances, and the trigger voltage F generating timing advances with the rise of the number of revolution, and thus the ignition timing characteristic with advanced angle having a prescribed inclination can be obtained.
