Inventor: HONMA YASUMASA
IPC: B22D7/10
Filed: 1983-08-12
Abstract: PURPOSE:To form easily a titled sleeve and to improve dimensional accuracy by placing a metal flask via a plate-shaped lower sleeve having the inside diameter smaller than the inside diameter of a casting mold on the top surface of the mold and pressing plate-shaped split type upper sleeves to the perpendicular inside wall of the metal flask. CONSTITUTION:A flat lower sleeve 3 having the outside diameter larger than the inside diameter of a casting mold and having the square-shaped inside diameter 5 similar to the mold 1 is placed on the top surface 2 of the mold 1 and further, a metal flask 7 of which the lower and 8 has the similar shape of the upper shape 6 of the sleeve 3 is placed and the horizontal part 4 of the sleeve 3 is press fitted to the surface 2. Split type upper sleeves 10 are then pressed to the perpendicular wall 9 of a metal flask 7 and corner pieces 11 are driven from above to fix closely the sleeves to the inside wall 9 without producing any space. Heat insulating or exothermic members are used for the sleeves 3, 10 and heat insulating and elastic members are used for the pieces 11. The sleeve is thus easily formed, dimentional accuracy is improved and the deformation and crack in the stage of pouring a molten steel are obviated.

Title: Manufacture of cold rolled steel sheet ungenerating uneven linear defects due to plastic work
Inventor: TAKAHASHI MASASHI
IPC: B21B3/00
Filed: 1978-11-30
Abstract: PURPOSE: To prevent uneven linear defects in the surface of the steel sheet to be generated during the plastic work, by preparing the rimmed steel, etc., containing specified amount of P from the molten steel, by giving the blooming work to this rimmed steel with 80W97% solidification shrinkage rate, and by executing the hot, cold, and skinpass rolling, etc.  
     CONSTITUTION: The rimmed steel, or capped steel containing 0.002W0.01% P is prepared from the molten steel; and the blooming is started unider the unsolidified condition with 80W97% solidification shrinkage rate of the bloomed slab; after that, the hot rolling, annealing, and skinpass rolling are executed. Thus, the generation of uneven linear defects due to the plastic work of the cold rolled sheet can be prevented. If the content of P is 0.01% or less, above defects are not generated even by the unsolidification rolling work. If the content of P is 0.002% or less, the energy saving can not be obtained economically. If the solidification shrinkage rate is under 80%, the stable operation of the blooming work becomes difficult; and if it is above 97%, the energy saving in the blooming work can not be achieved.

Filed: 1990-06-08
Abstract: PURPOSE:To obtain a flicker effect ad enhance an eye catch effect with eyes by actuating a trigger circuit with a timing circuit, and causing a luminous tube to emit light at a specific frequency. CONSTITUTION:A capacitor 17 of small capacity is charged with a capacitor charging circuit 18, and a trigger circuit 15 is actuated with a timing circuit 16, thereby causing a xenon discharge lamp 12 to emit light at a rate of 40 to 60 times per second. As a result, illumination can be made to have a flicker effect, and it is possible to increase an eye catch effect for eyes to catch the illumination. In this case, the luminous power of the xenon discharge lamp 12 is taken at 1 to 10% of rated power enabling stable positive column emission. As a result, a positive column generated in the xenon discharge lamp 12 becomes narrow and unstable, and changes a position in zigzag, and from (a) to (c) via (b), as illustrated. The positive column, therefore, looks as if oscillating. According to the aforesaid construction, an electrical decoration effect can be enhanced.

Filed: 1987-06-15
Abstract: PURPOSE:To facilitate system construction and to obtain a detection system with present position detection accuracy by allowing a receiver mounted on a vehicle to receive an ultrasonic wave signal from a vehicle sensor and extracting a modulation signal characteristic to the installation position. CONSTITUTION:A column 3 is provided nearby a passage 2 at a prescribed position in a road traffic network and the vehicle sensor to which an ultrasonic head 5 and a transmitter receiver 6 are fitted is installed. The vehicle sensor sends out an ultrasonic wave signal on which modulation intrinsic to the installation position is imposed.

Then when the vehicle 1 comes to nearly right below the ultrasonic head 5, the microphone 7 receives the ultrasonic wave and the receiver 8 generates counted number data corresponding to the frequency. The logical arithmetic part of the receiver 8 compares the count number data with plural frequency count number data stored previously in a position memory to extract installation position data on a corresponding vehicle detector, and outputs it as vehicle current position detection data.

Title: Overhead projector
Inventor: USHIRO SHIGEAKI
IPC: G03B21/132
Filed: 1987-06-15
Abstract: PURPOSE:To form a secondary original while keystone correction is executed by processing a reading signal from a reading head,newly incorporating a keystone correction means and recording on a recording medium with a recording head based on the process signal. CONSTITUTION:When a screen is set, the position and the height of an overhead projector are estimated by considering the size of an image on the screen surface 35 and the convenience for the user of the projector. If the user wants to adjust the height of the projected image, the angle of mirror is adjusted. When the angle of mirror is out of 45 deg., the process for the keystone correction is added to a copying mechanism. When the angle of mirror is not altered and it is 45 deg., a keystone effect is not given to the projected image. Then, the secondary original is formed in the ratio 1:1 in a copying device. Thus, the secondary original whose magnification on the screen is kept constant without depending on a spot can be formed.
