Title: Security module
Inventor: MARU TSUGIO
IPC: H04W88/02
Filed: 1990-04-28
Abstract: PURPOSE:To prevent a KEY code from being read by allowing a control circuit to erase the KEY code at access while a nonvolatile memory is accessed externally to check the memory. CONSTITUTION:A random data inputted through a serial interface circuit 301 is ciphered at a cryptographic circuit 303 by using a KEY code in a nonvolatile memory 302. A ciphered data is sent again through the circuit 301. An internal bus is isolated from an external device by using a control circuit 304 in a one- chip microcomputer 30 when a test terminal is inactivated during the normal operation. Thus, the circuit 303 and the memory 302 are accessed in the inside but the state is not observed externally. In the case of a check or an illegal use, the test terminal is brought into an active state and the circuit 304 is used to connect the internal bus and the external bus, and then the memory 302 and the circuit 303 are accessible through the external bus. However, clear pulse is outputted from the control circuit 304 and clears the content of the memory 302, that is, the KEY code.

Title: Optical modulator
Inventor: MACHIDA YOSHIHIKO
IPC: G02F1/135
Filed: 1989-05-08
Abstract: PURPOSE:To obtain a compact optical modulator which enhances the efficiency of utilizing the light of a light source by admitting the light from a thin-film electroluminescence element of an end face light emission type into the thin-film waveguide layer in contact with a clad layer consisting of a liquid crystal and changing the refractive index in the clad layer by an electric field. CONSTITUTION:The thin-film electroluminescence element (ETFEL) 111 of the end face light emission type is formed on a quartz substrate 101 and the thin-film waveguide layer 121 is formed to cover the end face thereof on the side from which the light is emitted. A transparent electrode layer 112 is provided on the thin-film waveguide layer 121. The liquid crystal 122 is sealed by using a sealant 123 between this substrate and a counter substrate 102 formed with an electrode layer 113. The refractive index in the liquid crystal clad layer changes when a voltage is impressed between the electrode layers 112 and 113 to impress the electric field in the direction perpendicular to the substrate 101 surface to the liquid crystal 122. Modulated light 131 is, therefore, released from the end face of the thin-film waveguide 121. The ETFEL 111 itself is the waveguide and since the directivity of the light to be emitted is high, the effective utilization of the light is possible.
