Title: Alarming circuit
Inventor: AKAHA HIDEKI
IPC: H04B17/00
Filed: 1987-02-28
Abstract: PURPOSE:To attain the generation and restoration of alarm suitable for circuit system by activating a circuit having a small time constant for the rapid alarm generation and activating a circuit having a large time constant for the restoration of alarm. CONSTITUTION:The time constant of a 2nd time constant circuit 16 is selected larger than the 1st time constant 12. Only a 1st time constant circuit 12 is acted to the voltage rise supplied to a comparator circuit 18 when an alarm input voltage rises to the alarm input 10 and the 2nd time constant circuit 16 acted dominantly to the voltage drop supplied to the comparator circuit 18 when the alarm input voltage descends. Thus, the alarm is generated rapidly by the time constant of the 1st time constant circuit 12 and the alarm is recovered slowly by the time constant of the 2nd time constant circuit 16.

Title: Screw structure for extrusion molding machine
Inventor: SATOU TADASHI
IPC: B29C48/03
Filed: 1979-04-15
Abstract: PURPOSE:To sufficiently knead and mix a molding material in an extrusion molding machine and increase the kneading effect with shearing force applied to the molding material, by using a screw having a screw body, a front end portion of which is eccentrically formed. CONSTITUTION:A molding material transferred in a solid state in an F section (feed section) around a screw body 1 is gradually heated to enter a P section (press section), where the molding material is pressed with a large power. In the P section, the molding material receives heat from a cylinder 5 and also shearing friction from the cylinder 5 and a screw S. Accordingly, the molding material is gradually plasticized as the temperature thereof increases. The molding material reaching an M section (melting section) in a molten state is subjected to laminar mixing in accordance with the rotation of the screw S. The molding material in the M section receives a large shearing power in a gap 7 between the inner circumferential surface 6 of the cylinder 5 and a surface 4 of an eccentrically formed portion of the screw S. Thus, the molding material is sufficiently kneaded.

IPC: E04B1/92
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of ferrite being used and to improve the performance for absorbing electronic waves in MHz-GHz band by specifying the gap rate between the electric field of arrival electronic waves and a ferrite magnetic material in the direction of a magnetic field for an electronic wave absorption wall in a wall with reinforced concrete and exterior finish materials. SOLUTION: A ferrite plate 1 is arranged at an equal interval of (c) in the direction of a magnetic field and is arranged at equal intervals of (a) in the direction of an electric field. A gap rate is the total ratio of the interval of the ferrite plate 1 in a predetermined range, where the ferrite plate 1 of a wall is arranged and is calculated from (interval/interval + ferrite plate)×100 for an arrangement at equal intervals. A gap rate c/d in the direction of a magnetic field is set to 20-50% and a gap rate a/b in the direction of an electric field is set to 25-45%. Even if the size of the ferrite plate 1 is adjusted appropriately and the interval is increased, sufficient reflection loss can be obtained in a UHF (300 MHz-3 GHz) band, thus reducing the amount of usage of the ferrite plate and reducing the weight of an electronic wave absorption wall.
