IPC: H04B10/293
Filed: 1992-09-29
Abstract: PURPOSE:To compensate a change in a signal light average power when the optical direct amplifier used as a booster is connected to a different optical transmitter. CONSTITUTION:An inputted signal light is branched by a signal light branching device 1, a peak level and an average level of optical power are detected from one signal light and the levels are used as mark rate information. The other signal light is inputted to an optical fiber amplifier 11, in which the light is amplified by a stimulated light from a semiconductor laser 17. An average optical power is detected from the amplified signal light by an average level detector 14 and the power is inputted to a control circuit 4 together with a mark rate information signal to control an output of the semiconductor laser 17. Thus, the gain of the optical fiber amplifier 11 is controlled and the gain depends on the average level and the output of a peak level detector 3 and is not dependent on an output of the optical transmitter (not shown in figure).

Abstract: PURPOSE:To detect abnormality of a program in an early stage, and to realize a high service life of a storage element by raising an alarm and executing a prescribed processing, when such the number of times of write being not generated in a regular operation is stored, within a set time. CONSTITUTION:A counter part 11 monitors an address outputted to an address bus 4 and data outputted to a data bus 3. Also, with respect to a storage element 5, the counter part monitors an address signal and other control signal at the time when write of data is executed, and when write is executed once to the storage element 5, its count is raised by '1'. In this case, a comparing part 12 compares the number of times of write to the storage element 5 outputted from the counter part 11 with a reference abnormality value 13, and outputs its result to an alarm part 14. Subsequently, when the comparing part 12 judges that the output of the counter part 11 is larger than the reference abnormality value 13, the alarm part 14 informs the fact to a CPU 1 by an interruption. In such a way, the CPU 1 stops its operation.

Title: Heat exchanger
Inventor: UCHIMURA KATSUNORI
IPC: F28D9/00
Filed: 1987-10-19
Abstract: PURPOSE:To improve the heat exchanging capacity by using multiple levels of overlapping corrugated fins to form inner fins in a flat tube in which heat exchanging medium floss to that the oil side heat releasing surface can be enlarged. CONSTITUTION:Inner fins 30 comprise two levels of upper and lower corrugated fins 31, 32. The corrugated fins 31, 32 divided into the upper and lower halves have a rectangular ridge, and are mutually connected. They are also connected to plates 8, 9 which form a plate tube 7. In this embodiment, the direction of corrugation crosses each other between the upper fin 31 and the lower fin 32. Since corrugated fins are overlapped in multiple levels, even if the overall height is same as that of a single level type, the height of corrugation can be reduced, and the pitch of corrugation can also be reduced as a result of the height reduction, enlarging the contact area of engine oil with the inner fins, e.g. the oil side heat releasing surface, which improves the heat exchanging performance.
