Title: Apparatus for detecting generation of high frequency magnetic field
Inventor: YODA KIYOSHI
IPC: H04B3/00
Filed: 1988-03-25
Abstract: PURPOSE:To ensure the protection of a receiver when a high frequency magnetic field is generated, by connecting one set of PIN diodes between a transmitter and the receiver, and controlling the ON and OFF of the diodes at the time of transmission and at the time of reception. CONSTITUTION:When a high frequency magnetic field signal is transmitted from a transmitter 5 to a first high frequency coil part 1 and a second high frequency coil part 3, a positive voltage is applied to a control terminal 22, and PIN diodes 20 and 24 are made to be an ON state. Thus, the high frequency magnetic field signal can be transmitted to the first and second coil parts efficiently. Since the diode 24 is in the ON state, a receiver 6 can be protected even if the high frequency magnetic field having large power is applied. Meanwhile, when the high frequency magnetic field signal is received from the coil parts 1 and 3, the diodes 20 and 24 are negatively biased and the OFF state is obtained. Thus, the transmitter 5 is isolated. As a result, the high frequency magnetic field signal is supplied only to the receiver 6.

Filed: 1986-03-31
Abstract: PURPOSE:To make it possible to give high heat shrinkage factor and comparatively low heat shrinkage stress to a film by a method wherein copolymer composition of epsilon-caprolactam and lauryl lactam is employed as the major constituent of raw resin. CONSTITUTION:A biaxially oriented film which employs copolymer consisting of 90-65mol% of epsilon-caprolactam and 10-35mol% of lauryl lactam as raw resin is formed so as to have the shrinkage factor at 100 deg.C by hot water of 30% or more both in longitudinal direction and in lateral direction and at the same time the heat shrinkage stress of 100-500g/mm<2>. In this case, the biaxially orienting temperature is preferably 120 deg.C or lower and the necessary draw ratio is 250% or more longitudinally and laterally in order to obtain the drawing effect necessary for molecular orientation, heat shrinkability and the like. Because the film is excellent in heat shrinkability and the heat shrinkage stress of the shrunk film is comparatively low, the film is suitable for the shrink wrapping of even matters to be packaged which is liable to get out of shape. Further, the film has low moisture and water absorption properties and consequently the slack due to moisture absorption after packaging is small.

Abstract: PROBLEM TO BE SOLVED: To improve the transfer accuracy of intricate and fine patterns formed on an optical mask by patterning the phase shift film on a mask substrate to the shapes resembling the plane shape with the circuit patterns to be formed on a semiconductor wafer or the inversion patterns thereof. SOLUTION: Metallic layers 3 are patterned and formed to prescribed shapes on the main surface of the mask substrate 2 constituting a mask 1a. The original picture of integrated circuit patterns is composed of light shielding regions A and transmission regions B. The one transmission region B comprises a part coated with a transparent film (a) and a part not formed with this transparent film 4a. At the time of exposure, a phase difference of 180 deg. is induced between the phase of the light transmitted through the transparent film 4a out of the light which is cast on the mask 1a and is transmitted through the one transmission region B and the phase of the light transmitted through the ordinary transmission regions B. These light rays weaken each other in the boundary parts between the light shielding regions A and the transmission regions B and, therefore, unsharpness is reduced.
