Title: Optical disk, metal mold for injection molding of optical disk and injection molding machine for optical disk production
Inventor: IIDA TETSUYA
IPC: G11B7/24047
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To prohibit the occurrence of warpage by residual stresses at the time of forming an optical disk by forming the embossements corresponding to recording signals on the one surface of a molded disk substrate and forming dummy embossments on the other surfaces. SOLUTION: A stationary metal mold 1 and a movable metal mold 2 are closed to form a cavity 17. The disk substrate is injection molded by injecting a resin into this cavity. A cutting pin 13 forms a central hole by boring the center of the disk substrate after the disk substrate is formed by solidification of the resin in the cavity 17. Either one of a first stamper 8 and a second stamper 14 transfers the embossement to the pits carrying information on the information recording surface of the molded dish substrate and the other thereof transfers the dummy embossements not carrying the information on the signal information reading surface of the disk substrate. The residual stresses of the molded disk substrate are made nearly symmetrical with the center of the thickness of the disk substrate and the occurrence of the warpage is substantially prevented.

Title: Grout material and grout estimating method
Inventor: NISHIYAMA TAKASHI
IPC: E02D3/12
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To accurately evaluate a filled state without depending on a lugeon test even in case where the color tone of the wall of a boring hole is similar to the color tone of a filled grout material. SOLUTION: Grout material formed by mixing cement with fluorescent paint to emit light under ultraviolet rays is injected and filled into the ground in a pressurized state inside a boring hole 1 bored in the ground composed of a rock bed and earth and sand being the object of improvement. Next, other boring holes 2 are provided within a prearranged injection area to expose the ground. When the ultraviolet rays are irradiated as luminescent rays to the wall face of the boring hole 2, the grout material filled in the ground emanates the fluorescent rays. Only a crack where the grout material has permeated is recognized. When this state is photographed by means of a bore hole camera or the like and observed, the filled state of the grout material into the ground can be evaluated.

Abstract: PURPOSE:To interrupt the primary side of a step-up transformer automatically and positively by a simple circuit when a neon discharge lamp is put out by failure by providing the secondary side of the step-up transformer with a means for interrupting the primary circuit of the step-up transformer composed of a light-emitting element and a photo-detector. CONSTITUTION:When any accident is generated and either section on the secondary side of a step-up transformer TF is disconnected when neon discharge lamps NT1-NT5 are put on continuously, the neon discharge lamps NT1-NT5 are put out instantaneously. Voltage generated at both ends of a resistor 1 dissipates at that time, and the emission of a light-emitting diode PD is stopped. Consequently, a phototransistor PTr is turned off, transistors Tr1, Tr2 are turned off and an actuating signal OPS is not transmitted over a TRIAC TR1 from a low voltage section LPP. Accordingly, the TRIAC TR1 is cut off, no voltage is applied to the primary side of the step-up transformer TF, and no high voltage is induced on the secondary side.

Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To enhance breakdown voltage characteristics and moisture resistance by molding a first supporting member at a temperature of glass transition point or below and then fusing fused thermoplastic resin at a temperature of glass transition point or above thereby molding them integrally. SOLUTION: At first, a first supporting member 1 is previously molded of thermoplastic resin and at least a coil 4 and an insulating board 2 are mounted thereon. It is set in a molding die and molded by injecting fused thermoplastic resin 3. Thermoplastic resin 4 for sealing is realized by injection molding, for example, and since the injection temperature of resin is as high as 300 deg.C, solder can be melted by the high temperature resin when an insulating board 2 for IC card having a circuit element mounted by soldering is inserted into the molding die and molded integrally. But since the module is covered with thermosetting resin, heat transfer to the solder is suppressed and the solder can be prevented from melting.

Filed: 1985-11-15
Abstract: PURPOSE:To obtain the titled wire having a less tendency for increasing the transmission loss due to a change of an used temperature and having an excellent bendability by arranging a coating layer composed of two layers comprising a thermoplastic resin which has a liquid crystal property in a melt state and displays a high elastic modulus and a low coefficient of a linear expansion and a thermoplastic resin having great bendability on the outer side of the optical fiber element wire. CONSTITUTION:The titled wire comprises the 2nd. coating layer 5 of the optical fiber having a relatively large orientation degree and the 3rd. coating layer 6 which is disposed on surroundings of said layer 5 and is the thin film (50-100mum the thickness) and is composed of the thermoplastic resin having a low orientation degree, such as polyamide and polyethylene, etc. In the titled wire, the usual 2nd. coating layer is constituted of a double layers. The distribution of the orientation degree of the 2nd. and 3rd. coating layers is adjusted in such a way that the orientation degree of the outer surface layer (the 3rd. coating layer) makes to the min. value, when the max. elongation force or the max. compression force at the bending of the core wire is loaded. Thus, as the outer surface layer (the 3rd. coating layer) has the lower elastic modulus locally in comparison with that of the inner layer (the 2nd. coating layer), and is rich in the elastic modulus, the titled wire may stand against the large elongation and compression forces resulted in giving the core wire having the excellent bendability.
