IPC: F16L37/12
Filed: 1994-12-28
Abstract: PURPOSE: To prevent a claw part from cutting through the outer wall of a pipe more than necessary by a method wherein a function to mount and demount a pipe on and from a pipe fitting body is dispersed to members. CONSTITUTION: A pipe fitting comprises a collet ring 36 having an internally protruding claw part 46 to couple a pipe 42; a movable resilient ring 64 through the force of which a claw part 46 is cut through the outer wall of the pipe 42; and an inclination ring 54 to release locking by the claw part 46. As noted above, since a function to mount and demount the pipe 42 on and from a joint body 10 is dispersed to the joint body 10, the shape of each member can be simplified. Thus, a metallic material formed through drawing can also be used. Further, an inner peripheral lock part 68 to regulate movement of the claw part 46 to the inner side is arranged at the inclination ring 54, whereby movement of the claw part 46 to the inner side is also regulatable. This constitution prevents the claw part 46 from cutting through the outer wall of the pipe 42 more than necessary.

Title: Tamper-resistant device
Inventor: KATO TAKEHIKO
IPC: G06F21/75
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To place an optical single crystal (LiNbO3, etc.), on a semiconductor circuit so that confidential information may not be decoded even when a laser beam is illuminated upon the crystal. SOLUTION: A dielectric scattering layer 201 containing dielectric particles 202 is formed on the protective layer 102 of a semiconductor circuit, such as the memory, etc. Since the particles 202 are scattered in the layer 201, electric field concentration is relieved as shown by electric force lines 103. When a LiNbO3 single crystal 104 is placed on a semiconductor chip, electric fields are relieved on the way to the surface of the single crystal 104 and no definite difference occurs in the refractive index of the crystal 104 even when the potentials at semiconductor gate electrodes 101 vary in accordance with information '0' and '1'. Therefore, confidential information is not able to be decoded even when a laser beam is illuminated upon the crystal 104.

Title: Frame synchronization monitoring circuit
Inventor: SUGA SEIICHI
IPC: H04L7/08
Filed: 1991-12-13
Abstract: PURPOSE:To save power of a switching work by monitoring the state of a specific bit in a frame synchronization signal and automating the validating and invalidating of a CRC function at the same time when CRC frame synchronization information is retrieved. CONSTITUTION:When a PCM communication device arranging a frame synchronization monitoring circuit is confronted with the PCM communication device having a CRC function, a synchronization information retrieval part 32 retrieves a specific bit composing the frame synchronization signal in the PCM signal from an input terminal 31 and outputs a frame synchronization confirmation signal. Next, a CRC frame synchronization information retrieval part 34 retireves the specific bit composing the CRC frame synchronization information and outputs a confirmation signal. Thus, a frame synchronization error notification signal from an error notification signal generation timer 35 is blocked by 3 input AND gates 37 and a frame synchronization monitoring is performed. When the PCM device having no CRC function is confronted, a CRC nonuse information retrieval part 33 retrieves the specific bit in this case and automatically invalidates the CRC function.
