Filed: 1986-07-18
Abstract: PURPOSE:To set or measure a potential of a place irradiated with beams without contact, by irradiating an electronic device with a plurality of charged beams consisting of potential measuring beams and voltage measuring beams and detecting amounts of secondary electron signals produced thereby. CONSTITUTION:A potential measuring beam 33 is applied as a pulse beam having a certain frequency and an amount of secondary electron signal produced thereby is detected by a secondary electron detecting circuit 24. A potential at the point irradiated with the beam 33 is obtained by a potential control circuit 25 from a difference between an amount of secondary electron signal detected by the circuit 24 when the beam 33 is ON and an amount of secondary electron signal when the beam 33 is OFF. When the beam 33 is applied to the point irradiated with voltage supply beams 31 and 32, the output of the potential control circuit 25 is switched over by a switching circuit 50 so as to be fed back to beam control circuits 26 and 27 for the beams 31 and 32 so that these control circuits 26 and 27 control the conditions of emitting of the beams 31 and 32 and a potential is set.

Abstract: PURPOSE:To enable removal of a casting at an optimum temp. by calculating the heat energy that a die absorbs from a molten metal in accordance with the temp. gradient between the two points in the die, and determining die opening by the heat energy. CONSTITUTION:Two temp. detecting elements 8, 9 spaced at different distances from the inside wall of a cavity 7 are provided near the casting plane of a movable die 4 in the direction where the heat flux from a molten metal flows. The electrical signals corresponding to the temp. from the elements 8, 9 are changed to voltage signals by input conversion circuits 10, 11.

Title: Production of flame retardant porous product and product produced by the same
Inventor: SALYER IVAL O
IPC: C04B41/46
Filed: 1998-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a flame retardant porous product used for heat energy preservation and the product produced by the same. SOLUTION: This method contains the treatment of the surface of a phase change material-containing porous product with an urea flame retardant. Urea forms an adduct with the phase change material at the time of being exposed to flame without containing combustion in the air (self-extinguishing property). The flame retardant does not contain halogens or metal oxides and therefore, the product does not release latently harmful halogenated material smoke or fume even at the time of being continuously exposed to flame.

Filed: 1990-06-28
Abstract: PURPOSE:To prevent the rapid reduction in the sound pressure level at a low frequency by mounting speaker units of a same characteristic to both buffle plates opposite to each other, covering a rear side of the one with a sound absorbing member and connecting the units electrically so as to be in operation in opposite phase.

IPC: B21D51/26
Filed: 1995-07-06
Abstract: PROBLEM TO BE SOLVED: To prevent a neck part from generating the discontinuity part by making the radius of curvature of the transition part to bind the necking part of a necking die and a parallel part. SOLUTION: A metal can 4 is necked-in with a necking die 1 and a circular column like core 2. The radius of curvature r of the transition part 14 to bind a necking part 12 of the die 1 and a parallel part 13 is made into the value within the range of r/D being 0.06 to 0.2. The external diameter D is an external diameter before necking the metal can 4. In a case of a value r/D being smaller than 0.06, a recessed part of the opening end side generating from being necked-in is made to have a small radius of curvature. The recessed part of the small radius of curvature is not vanished with the next necking-in and it remains as it is. Accordingly, the smooth neck part can be not formed. In a case of r/D being over than 0.2, after forming, a large radius of curvature is made and the buckling is generated on the can drum part at the next necking-in time.
