Abstract: PURPOSE:To switch trains of hologram diffraction grating facets to be utilized easily while holding the length of an optical path constant, and obtain two copy sizes easily by displacing two prism or roof mirrors to either of two positions selectively. CONSTITUTION:When the prisms P1 and P2 are set as shown by solid lines, reproduced light 5 is reflected by the left-side slanting surface of the prism P1 to reach a mirror M1, made incident to a facet A, and diffracted by its hologram diffraction grating, and the diffracted light is reflected by a mirror M2 and the left-side slanting surface of the prism P2 and deflected in the center surface as the boundary between facets A and B within a specific angle range, so that the light is projected. When a train of the facet B is used, the prisms P1 and P2 are displaced to positions shown by broken lines at the same time. Then, the reproduced light 5 is reflected by the right-side slanting surface of the prism P1 and mirror M1 to enter the facet B and is diffracted by its hologram diffraction grating, and the diffracted light is reflected by the mirror M2 and the right-side slanting surface of the prism P2, so that the light is projected.

Abstract: PURPOSE: To prevent direct influences of the reaction force of the knockout cylinder to products and to eliminate causes for deformations of products, by piercing stopper rods through the right and left and sections of the knockout bar and installing the second stopper to the bottom section of the stopper rods.  
     CONSTITUTION: Stopper rods 7 fixed to a crown 1 are pierced through both end sections of a knockout bar 5 connected to rods 4 of knockout cylinders 3, and the second stopper 8 is fixed to the bottom section of each stopper rod 7. The first stopper 11 of the knockout bar 5 is installed to both sides of a slide 2, and an upper die 12 is firmly installed to the bottom of the slide 2. When the slide 2 descends and reaches the bottom dead center, the knockout bar 5 is supported by the second stopper 8 and a space is formed between a knockout pin 13 in the upper die 12 and a knockout rod 9 of the slide 2. In this way, the reaction force of the knockout cylinder 3 is received by the second stopper 8 and the flow of blanks being formed becomes continuous one, and thus, no impressions of the knockout pin 13 are left on the surface of products.

Title: Vacuum defoaming unit for molten glass and method for making the unit
Inventor: TAKEI YUSUKE
IPC: C03B5/225
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To provide the subject defoaming unit so designed that the flow channel subject to contact with molten glass is made of dense refractory brick and the smoothness of the contact surface of bricks in contact with the adjacent bricks is set at a specified level or lower so as to prevent the molten glass from leaching through the joints. SOLUTION: This molten glass defoaming unit is so designed that, the smoothness of the contact surface of dense bricks constituting an inner surface brick layer 32a representing a flow channel subject to contact with molten glass G with the adjacent bricks is set at <=0.5 mm, and each of the gaps between bricks adjacent to each other at <=1 mm; thus, through mutual contact of bricks without using any joint sealer at the brick contact surface, the above joint gaps are filled with high-viscosity vitreous matter leached at high temperatures from the inside of the dense bricks to effect mutual binding of the bricks; the high-viscosity vitreous matter thus leached stays in the gaps and does not issue;  therefore even if the molten glass try to intrude into the gaps, the high-viscosity vitreous matter blocks the action, thereby preventing back-up bricks and a thermal insulation material lying deep in the joints from being eroded.

Title: Furnace chamber with clear light passage
Inventor: NIIRU ANSONII JIYONSON
IPC: F27D99/00
Filed: 1990-07-06
Abstract: PURPOSE: To suppress contamination of the viewpath in a furnace enclosure due to steam and fine particles by determining the sign of charges existing on mist particles generated in an enclosure through intensive heating and applying a voltage of same sign to a metal mirror face. CONSTITUTION: A high voltage is applied from a power supply 60 to a metal mirror 40 through a lead wire 62. Lead wire 64 from the power supply 60 is grounded to the side wall 66 of an enclosure 10. Since a voltage of 5-39 kV is applied to the mirror 40, an electric field of same sign (positive or negative) as the charge on the particle is generated around the mirror 40. Type of charge on the particle is determined by observing adhesion of particles onto the metal plate through a window while applying a voltage thereto. If the charge on the particle is negative, a gaseous or particulate substance charged negative is repelled when a negative voltage is applied to the metal mirror face. Consequently, the metal mirror face is kept clean and a clear viewpath is ensured for the light incident thereto.
