IPC: B32B27/32
Filed: 1988-04-19
Abstract: PURPOSE:To obtain a film, which does not break even by being subjected to shocks by a method wherein the number of carbon atoms in alpha-olefin and the bonding strength between a flat-tube-like film made of ethylene-alpha-olefin copolymer and a sheet-like film are specified in a packaging film, which is produced by bonding the flat-tube-like film and the sheet-like film. CONSTITUTION:The packaging film concerned is produced by bonding a sheet- like film onto at least one of the surfaces of a flat-tube-like film made of ethylene-alpha-olefin copolymer. The number of carbon atoms in the alpha-olefin is set to be 5-10. The bonding strength between the flat-tube-like film and the sheet-like film is set within the range of 200-800g/15mm width. The strength against falling of the packaging film consisting of copolymer formed from the reaction between ethylene and alpha-olefin, the number of carbon atoms of which is 4 or less, is insufficient. If the bonding strength between the flat-tube- like film and the sheet-like film is below 200g/15mm width, the bonding strength is weak and the films are easily separated from each other. If said bonding strength exceeds 800g/15mm width, the packaging film is weak to shock and fragile to falling.

Abstract: PURPOSE:To eliminate the effect due to the transient fluctuation in case the carrier is regenerated from the two-phase PSK modulation wave, by extracting only the  area where the modulation wave exceeds the threshold level and then regenerating  the carrier from that area. CONSTITUTION:Two-phase PSK modulation wave (a) is supplied to gate circuit 10 through delay circuit 9. While signal (c) which turns on circuit 10 is generated from gate driving circuit 11 at the area where wave (a) exceeds the threshold level of + or -K in terms of demodulation wave (b) of synchronous detector 8. The delay time of delay circuit 9 features such value that a coincidence may be secured between the time during which wave(a) is transmitted to the input of circuit 10 from input end 1 and the time when signal (c) is generated via wave (a). As a result, burst-type two-phase PSK modulation wave (d) can be obtained at the output of circuit 10 with reduced fluctuation of the amplitude and the phase.

Title: Optical disk
Inventor: NISHIZAWA AKIRA
IPC: G11B7/24062
Filed: 1995-03-29
Abstract: PURPOSE: To prevent a reproducing operation from taking place by accident by providing a low reflectance area where the reflectance is <=40% in a part corresponding to a read-in area of the optical disk on the side of nonreproducing surface. CONSTITUTION: When the optical disk 1 is mounted on a reproducer, an optical pickup 10 is automatically moved along a guide rail 11 in the radial direction of the disk, and is positioned in the read-in area 8 of the optical disk 1 to emit laser light L. At this time, reflected light of the laser light shows a larger reflectance than 40% because the optical disk 1 is normally mounted with its reproducing surface down, and hence the reproducing operation is continued by the optical pickup in recognition of the mounted optical disk by detecting strong reflected light. Then, information consisting of signal pits 2 formed on a substrate 3 is read out by utilizing a changing rate of intensity caused by an optical phase difference.

Abstract: PURPOSE:To prevent the plunging of a consumable electrode into weld zones on accouut of its inertia and the generation of a globular lump at the leading end of the electrode in a welding machine for welding under feeding of said electrode by changing the output voltage of a welding power source at the end of welding to a pulse form within a period when it is maintained low. CONSTITUTION:When the signal during working from a starting circuit 13 is annihilated  at the end (b) of welding, a control circuit 18 interrupts the output immediately and therefore an electric motor 20 is decelerated quickly and stops after the time DELTAt. On the other hand, a circuit 9 changes over and transmits the output of a reference voltage  setter 8 from the same setter 7. Delay switching circuits 14, 15 start clocking and the latter times out after the time t2 and the former after the time t1(t1>t2). Upon timing out of the circuit 15, a delay switching circuit 16 starts timing. During the time of t2 after the time (b), the low voltage of the setter 8 is supplied to the welding power source and the voltage E2 lower than that during welding is supplied to a torch 3 and the work 4. During the time of the set time t3 of the circuit 16 after this, the output is supplied to a switching circuit 11, and the voltage Ep corresponding to the set value of a setter 10 in lieu of the setter 8 is outputted. Thereafter, the circuit 11 supplies the voltage E2 until the t1 times out.

Title: Apparatus for measuring axial force of rail
Inventor: KASHIWATANI KENJI
IPC: G01R33/12
Filed: 1984-05-18
Abstract: PURPOSE:To make it possible to measure the stress in the axial direction of a rail, by differentially connecting magnetic anisotropy detecting coils so that disturbance magnetic fields are offset. CONSTITUTION:Detecting coils 17-1 and 17-2 of one magnetic anisotropy sensor 15-1 are cumulatively connected. Detecting coils 19-1 and 19-2 of another magnetic anisotropy sensor 15-2 are similarly connected. When the sensors 15-1 and 15-2 are arranged at an equal angle with respect to a rail, the voltages, caused by disturbance magnetic fluxes, which are induced in the detecting coils 17-1 and 17-2 and 19-1 and 19-2, become equal. When the coils 17-1 and 17-2 and 19-1 and 19-2 are differentially connected, the voltages are offset, and no output appears across output terminals 12. When exciting coils 18-1 and 18-2 are connected out of phase, the signal voltages, which are induced in the detecting coils 19- 1 and 19-2 become out of phase. Since the detecting coils 19-1 and 19-2 and 17-1 and 17-2 are differentially connected, the signals are added, i.e., the result is the twice the original voltage. Therefore, the detected signal of the degree of magnetization of the rail by the exciting coils of the sensors themselves becomes twice the original value. The disturbances are offset, and the proper signal can be positively detected.
