Title: Mud material for closing tap hole of blast furnace
Inventor: NAKAMURA YUKIHIRO
IPC: C21B7/12
Filed: 1995-02-27
Abstract: PURPOSE: To obtain a mud material which is used for closing a tap hole after discharging the molten iron and molten slag in a blast furnace from the tap hole, deals with prolonging of tapping time and a trend toward a higher molten iron temp. and has the corrosion resistance higher than heretofore. CONSTITUTION: This mud material for closing the tap hole of the blast furnace is formed by adding a proper ratio of a binder to 100 parts main raw material consisting of one or >=2 kinds among silicon carbide, chamotte, carbon, agalmatotite, clay, silicon nitride, silicon nitride iron and metallic powder. Alumina and magnesia are added in addition to this binder to the main raw material at 15 to 400 parts in total in such a manner that the ratio of the magnesia/ alumina by weight attains 0.1 to 0.6. As a result, the corrosion resistance and wear resistance are improved as compared with the conventional mud materials and the dealing with a blast furnace operation of a high tapping ratio is possible. Since there is no increase in the bore even if a hole of a large bore is opened from the initial period, the long-term tapping is made possible.  The excellent performance capable of tapping the tapping slag in the furnace up to the last with good balance is thus exhibited.

Title: Production of magnetic recording medium, magnetic recording medium, and silver halide photographic sensitive material
Inventor: NAKAJIMA JO
IPC: G11B5/716
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To make a magnetic recording medium possible to have excellent transparency and slipperiness and to obtain high magnetic output by specifying the shearing rate acting on an upper layer transparent magnetic recording layer coating liquid adjacent onto a lower layer transparent magnetic recording layer coating liquid on a base side to a specified value or a bove and applying two layers of transparent magnetic recording layers in double layers by a wet-on-wet system on one surface on a base. SOLUTION: At the time of the wet-on-wet double layer coating, by increasing the shearing rate of the upper layer transparent magnetic recording layer coating liquid, the thin magnetic recording layers having excellent magnetic characteristics can be obtained. The formation may be achieved by applying the upper layer transparent magnetic recording layer coating liquid faster and thinner than the lower layer transparent magnetic recording layer coating liquid. More specifically, by setting the shearing rate preferably at >=2×104 sec-1, not only the transparent and smaller film thickness can be obtained but the orientability after drying can be improved and the magnetic characteristics can be enhanced as mechanical orientation occurs strongly at the coating application layers.

Title: Film unit with lens
Inventor: ISHIGURO MASANORI
IPC: G03C3/00
Filed: 1993-03-22
Abstract: PURPOSE:To prevent the generation of a short shot in a release button at the time of injection molding of a front cover by forming an thinned part in an arm part in such a manner that the resin sent from a thin part flows nearly simultaneously to a button part and the terminal of the arm part. CONSTITUTION:The release button 6 is integrally molded of the resin sent from a horizontal direction to the thin part 20 at the tine of injection molding of the front cover. The resin flows not only to the thin part 20 but to the arm part 31 as well when the front end of the flow arrives at the middle of the thin part 20 at the time of this injection molding. The flow of the resin slows down thereafter and resultantly flows toward two directions, horizontal and vertical. The resin sent in the horizontal direction flows into the button part 30 and the resin sent in the vertical direction into the arm part 31, respectively. The arm part 31 is formed smaller in volume and thickness by the thinning and, therefore, the resin arrives eventually simultaneously at the terminals of the button part 30 and the arm part 31 at this time.

Title: Weight sensor
Inventor: HOSOMI FUMIO
IPC: G01G7/04
Filed: 1989-03-15
Abstract: PURPOSE:To obtain a small sensor with a simple construction by making an electromagnet with a tray float above a fixed electromagnet as opposed thereto to measure a load based on a variation of an applied voltage of the electromagnet when an interval therebetween is controlled constant. CONSTITUTION:An electromagnet 8 is fixed on the bottom of a holder 10 and an electromagnet 9 with a tray is floated. When an object is placed on the tray 11, the electromagnet 9 is displaced so that an electrostatic capacitance tends to change between electrode plates 12 and 13 provided on the electromagnets 8 and 9. This change is detected by an electronic circuit 14 to control a voltage so that an interval of electrode plates 12 and 13 will not change to increase magnetic forces of the electromagnets 8 and 9. As a result, a load working on the tray 11 is indicated on a weight indicator 15 from a change in the voltage corresponding to an increment of the magnetic forces. This enables a measurement without any mechanical displacement between the initial state and a state after the application of a load thereby producing a simple and small sensor.
