Title: Manifold for injection molding
Inventor: TANAKA SHIYOUJI
IPC: B29C41/00
Filed: 1980-12-10
Abstract: PURPOSE:To uniformly inject a melted material from gates into cavities, by throttling the sectional area of a runner remote from a sprue. CONSTITUTION:A longitudinal main runner 2 is drilled in communication with the sprue 7 formed in the upper center of the manifold and extends through the manifold 1. A plurality of branched runners 3 are provided in communication with the main runner 2 and also in communication with the cavities 9 defined by upper and lower molds 10, 11 via nozzles 8 and gates 14. The main runner 2 of the manifold 1 is provided with screw-type throttle valves 6 to reduce the inlet area of the branched runners 3 and the sectional area of the main runner 2 remote from the sprue 7. Therefore, since using the screw type throttles valves, the sectional area of the runner remote from the sprue can be throttled, highly reliable molded items can be obtained in the injection molding for producing many items at a time.

Abstract: PURPOSE:To form an edge with a good appearance by bending downward an edge along the longitudinal direction and cutting horizontally the foundation of the bent part in a decorative strip made according to the steps of first superposing on the upper surface of a base a patterned strip and then superposing thereon a transparent synthetic resin layer. CONSTITUTION:A longitudinally strip-shaped base 2 made of a synthetic resin is formed with protrusions 10 on both sides thereof in order to secure the superposition of other material, and a patterned strip 3 is superposed over the base 2. The patterned strip 3 is formed from a colored synthetic resin, etc., having a metallic color different from that of the base 2. A desired decorative strip 1 is obtained by superposing a transparent synthetic resin layer 5 on the base 2 and the patterned strip 3. When finishing the end of such decorative strip 1, an edge excellent in decorativeness is obtained by such a manner that at predetermined positions in the vicinity of both edges of the decorative strip 1 a transverse recess 7 is formed to bend the decorative strip downward under heating while using the recess 7 as a boundary to form a cutting-off bent part 6 and thereafter to cut the foundation of the bent part 6 horizontally.

Title: Developing device
Inventor: YOSHIEBISU TAMIO
IPC: G03G15/08
Filed: 1987-07-09
Abstract: PURPOSE:To enable the formation of always normal images by providing a shutter to a passage for supplying a developer to a developing section and opening and closing the passage to prevent developing conditions from changing. CONSTITUTION:The developer is supplied to a developing roller 2. The developer is sent, upon ending of the development, to a conveying roller 4 by rotation of the roller 2 and is further conveyed by the roller 4 so that the developer is circulated and supplied along a scraper 6 to an agitating roller 7. The control to stop the supply of the developer is thereafter executed when the need for development with a developing device is eliminated upon ending of the development of a photosensitive body 3. Since the shutter 8 is thereby rotated 90 deg. and is stopped, the non-slit part of the shutter 8 closes an inlet 12 and outlet 13 of the developer supplying passage. The developer is, therefore, no longer supplied to the roller 2 and is set in a non-developable state. The spacing between the developing part and a recording medium is always constant and the developing conditions do not change according to this constitution. The always normal images are thus formed.

Title: Bolt fastening device
Inventor: OONO KATSUYOSHI
IPC: B23P19/00
Filed: 1986-07-23
Abstract: PURPOSE:To provide a bolt fastening machine of good performance by furnishing it with a bolt socket having at its tip a socket hole for fitting with the head of each bolt, so that the bolt socket can be coupled with a rotary shaft via a universal joint, and thereby providing possibility of fastening even though axes of bolt socket and bolt are dislocated from each other. CONSTITUTION:The rotary shaft 6 of a bolt fastening machine 4 is rotated and a bearing housing 5 is sunk to a bolt 3. If, at this time, a bolt socket 9 is dislocated from the axis of the bolt 3, the tip of the bolt socket 9 contacts the oversurface of the bolt head 3a to be hindered from further sinking. The bearing housing 5 however continues sinking, so that an expansion/contraction shaft 8 pushes the bolt socket 9 to the bolt head 3a while said shaft 8 is contracting against the resilience of a spring 17. Thereafter the bolt socket 9 makes conical motion with a boss 16 as fulcrum, to compress a resilient member 13 in one direction. Socket hole 9a and the head 3a of bolt 3 will now mate together, and the bolt 3 is fastened with rotation of bolt socket 9.

Title: Back washing of ceramic filter
Inventor: OGAWA TAKASHI
IPC: B01D29/62
Filed: 1989-07-05
Abstract: PURPOSE:To retain good back washing effect for a long time by force fitting raw liquid into a ceramic filter in the state of closing on-off valves of a raw liquid outlet and a filtrate outlet, rising the pressure of the raw liquid in the filter, and then opening the on-off valve of the raw liquid outlet instantly. CONSTITUTION:When a tubular ceramic filter 6 installed in a filter container 5 is back washed, raw liquid is force fitted into the filter 6 in the state of closing on-off valves 7 and 8 installed at a raw liquid outlet and a filtrate outlet and the pressure of the raw liquid in the filter 6 is risen, and then the on-off valve 7 of the raw liquid outlet is opened instantly. That is, as the pressure on the raw liquid side of the filter is lowered instantly, a substance clogged in the filter is pushed out from the filtrate side to the raw liquid side. Said action can be applied to the whole surface of a filtered surface, and the back washing effect better than that of the processes heretofore available can be provided for a long time.
