Title: Manufacture of polyamide mold
Inventor: FUKAI HIROSHI
IPC: B29C39/00
Filed: 1985-04-08
Abstract: PURPOSE:To prevent the generation of a crater-like cavity due to a local polymerization contraction and form smooth-surfaced moldings by providing a positive differential in mold releasing property in the internal surface of a molding die, specially between different surfaces. CONSTITUTION:A molding die is composed of a box-type stainless steel bottom force and a flat stainless steel top force. For instance, a silicon grease (mold lubricant) is applied to the bottom force through spraying, and is not applied to the top force. Next, after controlling the temperature of the molding die to 150 deg.C, a substantially anhydrated cyclic omega-lactum subjected to adequate anhydration process under conditions such as 100 deg.C, 2mmHg, for instance, about 500g epsilon-caprolactum is equally divided into two vessels by scale. 1.0g of sodium hydroxide is added to the vessel A as a catalyst and 15.0g of toluendiisocyanate to the other vessel as a polymerization accelerator. Then the contents of the vessels A, B are injected into the bottom force of the molding die and the top force is quickly set to hermetically seal the molding die. As a next step, the contents are allowed to be cured for about 20 minutes and after the completion of molding, the flat moldings are released from the molding die.

Title: Detection gauge for detecting deformation amount of living body
Inventor: TSUCHIYA KAZUO
IPC: G01B7/16
Filed: 1984-04-16
Abstract: PURPOSE:To make it possible to simply measure the large deformation amount of a living body, by detecting the deformation amount of the living body from the elastic base body adhered to the living body and the elastic electronic resistance element extending and contracting in integral relation to said base body. CONSTITUTION:A linear elastic electric resistance element 3 comprising a highly extensible conductive polymer material is adhered to an elastic base body 2 comprising an electric insulating and highly extensible long rectangular thin plate shaped polymer material by an adhesive, so that the base body 2 and the resistance element 3 integrally extend and contract, to constitute a deformation amount detection gauge 1. Then, this detection gauge is adhered to a part to be measured such as the human body so as to allow the longitudinal direction of the base body 2 to match with the extending and contracting direction of said part to be measured. Next, the change in the resistance value of the resistance element 3 extending and contracting along with the extension and contraction of the part to be measured such as the human body is measured to detect the deformation amount of the part to be measured. In this case, the connection of the gauge 1 to an electric resistance meter is performed by grasping the terminal part 5 of the resistance element 3 by the chip 6 connected to a lead wire. Therefore, simple measurement can be performed.

Abstract: PURPOSE:To improve noise resistance and an insulating quality, by detecting a load using light through attaching of a strain-detecting optical fiber, deforming corresponding to the deformation of an object to be measured due to a load, and a dummy fiber, being not influenced by the deformation, to the object to be measured. CONSTITUTION:A strain-detectong optical fiber 6 is attached to an object 9 so that it deforms conrresponding to the deformation when it deforms due to an external force F, and meanwhile, a dummy fiber 5 is attached to the object 9 in a condition that it is not influenced by the deformation of the object 9. Laser light, radiated from a laser oscillator 1 is separated via a beam splitter 2, it enters the two fibers 4 and 5, and it is projected on a screen 7 through a jetting ends 6 located parallel to each other. The object 9 to be measured deforms due to the external force F thereupon, and the strain-detecting optical fiber 4 deforms corresponding to the deformation of the object 9 to change length of an optical path, which results in creating an interference fringe on the screen 7. This permits the detection of a load.

Inventor: MATSUDA MITSUHIRO
IPC: H04N7/18
Filed: 1995-03-31
Abstract: PURPOSE: To simplify the equipment and to make the equipment small in size by allowing a band block filter of a slave set to block passing of a 1st band in the vicinity of an audio frequency and allowing a band block filter of a master set to block a signal for a 2nd frequency band. CONSTITUTION: A video signal is fed to a band block filter BEF 15, which blocks a signal in a 2nd frequency band (300-600Hz) included in a band in the vicinity of the audio frequency and a video signal other than the block band is fed to an input output section 13. On the other hand, an audio signal is fed to a BPF 12, which passes a signal at a 2nd frequency band and the resulting signal is fed to the input output section 13. A block band of a BEF 221 of a master set is selected to be 300Hz to 6kHz and a pass band of a BPF 222 is selected to be 300Hz to 6kHz to form a separate means 22. Thus, the separation of a video signal at a frequency band of 60Hz to 6MHz except a 1st frequency band, that is, 250Hz to 6.5MHz and an audio signal at a frequency band of 300 to 6kHz is simplified.
