Title: Switching system between duplexed system and simplexed system
Inventor: OKABE KENICHI
IPC: G06F11/20
Filed: 1990-05-09
Abstract: PURPOSE:To accurately switch a system even if a fault such as clock stack in a duplexed system occurs by outputting a standby identification signal when a frame in out of synchronism detection circuit and a stack supervisory circuit output the detection signals. CONSTITUTION:When the fault occurs in a frame clock, a master clock and/or a frame, all of which are extracted from the first extraction circuit 1 of a duplexed device, system switching identification information, a frame in out of synchronism alarm and/or a signal showing the stack of the master clock are generated from a second extraction circuit 3, the frame in out of synchronism detection circuit 5 and/or the stack supervisory circuit 7. Even if the extraction circuit 3 stacks a switching identification signal as an in-use system identification signal, the in-use system identification signal is outputted from a mask processing circuit 9 as the standby system identification signal. Thus, the system can accurately be switched without being influenced by the fault such as clock stack which occurs in the duplexed system.

Title: Thin film resistor
Inventor: KATO SHIGEKAZU
IPC: H05K1/16
Filed: 1988-05-18
Abstract: PURPOSE:To relieve the stress which a conductor film exerts on a resistor and prevent the development of cracks at a boundary, by making notches at the parts of the conductor film along its boundary. CONSTITUTION:A resistance film 6 is formed on a substrate 5 that acts as an insulator and a conductor film 7 is laminated on the film 6. Parts 1 and 2 that act as electrodes of the conductor film 7 are covered by a photoresist and the like. Then, an electrode pattern is formed by removing the conductor film 7 other than the foregoing parts 1 and 2 through etching. When the electrode pattern is formed, notches 4 are partially made by etching on the electrode 1 along the periphery of the resistor 3. Consequently, when a completed thin film resistor receives heat history, the notches 4 relieve the stress which is generated at a boundary 8 between the resistor 3 comprising the single layer part of the resistor film and the electrode 1 comprising a part laminated by both resistor and conductor films. The crack development of the resistor 3 is thus prevented.
