Title: Low pressure casting apparatus
Inventor: HAYASHI KATSUZO
IPC: B22D18/04
Filed: 1987-10-29
Abstract: PURPOSE:To efficiently execute low pressure casting and to enable squeeze casting by cutting off a valve arranging between a stoke and a mold after pouring molten metal into a cavity in the mold through the stoke. CONSTITUTION:The molten metal stored in a holding furnace is pushed up in the stoke 1 with pressurized gas and poured into the mold cavity 6 through a sprue 5 in the mold 4 and solidified in there to obtain the casting. In the above low pressure casting, the valve 7 providing valve body 8 vertically sliding in the valve body guide 9 between the stoke 1 and the mold 4 is arranged. After completing the pouring, the valve body 8 is descended to cut off the valve 7. By this method, while preventing back flow of the molten metal into the mold cavity 6, by leaking the gas at upper part of the stoke 1, the molten metal in the stoke 1 can be returned back to the holding furnace. Together with this, by pressurizing with the volume of the valve 7, the squeeze effect to the molten metal is obtd. Further, a part of casting 10 of the valve 7 is made to separatable and then, maintenance of the valve 7 is facilitated and also the valve body 8 is desirable to facilitate the removal by making the constitution, which remains the gap between the valve body and the inner face of the passage under cut-off condition.

Abstract: PROBLEM TO BE SOLVED: To surely execute recording and reproducing of information on recording media varying in substrate thicknesses and to reduce the size over the entire part by using an objective lens varying in the focal lengths between a central part and a peripheral part so that light beams may be made incident effectively on the respective central and peripheral parts. SOLUTION: The objective lens 4 has the focal lengths varying in the central part 4a and the peripheral part 4b and condenses the light beams from the semiconductor laser 1 to the recording media 5, 6 of a large substrate thickness and a small substrate thickness. At this time, all of the laser beams are made incident only on the central part 4a of the lens without the beam conversion by a beam shape converting means 3. The light beams are made incident on the recording medium 6 by converting the beams to the beams of a ring band shape in section by the means 3 and making all of these beams only on the peripheral part 4b of the lens 4. The light beams are effectively utilized for the recording media 5, 6.  As a result, the exit power of the semiconductor laser 1 is controlled, by which the information is surely recorded to and reproduced from the recording media 5, 6 varying in the substrate thickness and the size over the entire part is reduced.

Title: Image forming device
Inventor: YAMAGUCHI TOSHITAKA
IPC: G03G21/10
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To make it possible for even an image forming device which uses recycled toner to obtain a satisfactory image over a long period of time by providing a cleaning means which removes, by means of a transfer roller, only opposite-polarity toner sticking to an image carrier. SOLUTION: A developed image formed on the photoreceptive drum 9 after sequential processes is transferred to transfer paper by means of a transfer device 5 and, at the same time, the transfer paper is separated from the photoreceptor to be carried to a fixing device. In this case, reversely-electrified toner attracted to the surface of a transfer roller 5a is scraped off the surface of the roller by a transfer-roller cleaning means 31 and recovered into a waste- toner recovery part 32. The cleaning means 31 consists of a cleaning blade. Because, in this manner, the reversely electrified toner is removed from the surface of the photoreceptive drum 9 by means of the transfer roller 5a and recovered in the waste-toner recovery part 32, only normally electrified toner can be recovered in a photoreceptor cleaner 6.

Title: Cut-off wall construction work
Inventor: KANZAKI YASUSHI
IPC: E02D5/20
Filed: 1986-11-18
Abstract: PURPOSE:To prevent the leakage of substances by raising the water-stopping property of a cut-off wall by a method in which a bottomed belted double film having a water impermeability is continuously inserted into an excavated trench, and a filler is charged into the double film. CONSTITUTION:A preset depth of trench 1 is excavated, and a stabilizer liquid 2, e.g., bentonite mud water, etc., is packed into the trench 1. A water- impermeable bottomed and belted double film 3 is continuously inserted into the liquid 2, and a filler 4 composed of a hydraulic or water absorptive swelling material is charged into the film 3 to a sufficient extent. The water-stopping property can thus be raised and can also be kept high since the filler 4 hardens or swells even when the cut-off film is partly broken. The leakage of substance can be exactly prevented and the deterioration and loss of the stabilizer liquid 2 can be prevented.
