Accordingly, electrons, holes are generated mainly not on the surface of the well but therein at the time of breaking down. A boundary on the surface of the well is weakened, electrons-holes to be implanted from the surface of the junction to the insulating film are reduced as compared with those of prior art example, and even if a protective diode breaks down, variation in its withstand voltage is small, and stable characteristics are always exhibited.

The DROPL light signal of a desired specific wavelength may be taken out at a terminal T3 by the voltage applied on the etalon element 30. The signal exclusive of the selected wavelength is reflected by the etalon element 30, is outputted from a terminal T2 and is transferred to another node. The ADD light signal of a specific wavelength may be outputted to a terminal T2 from the transmitted light signal from the self-node made incident from a terminal T4 by applying the voltage meeting the output wavelength to the etalon element 30.

Title: Manufacture of rare earth element magnet
Inventor: ISHIBASHI TOSHIYUKI
IPC: H01F41/02
Filed: 1989-11-07
Abstract: PURPOSE:To manufacture an easy-to-use rare earth element magnet having high performance and an easily designable magnetic circuit by adhering two or more magnets by pressure adhering or explosion adhering without using adhesive. CONSTITUTION:Two samples formed of quenched thin band of Nd13Fe82.7B4.3 by twice high temperature compression moldings are prepared, upper and lower surfaces to be adhered are mechanically processed, and explosion adhered. As a result, the two samples are very strongly adhered to obtain samples of about 7.6mm in height. This is because, since the opposed surfaces of the magnets become clean by an impact wave due to an explosion and pressed by high speed energy immediately thereafter, adherence having substantially the same strength as materials not obtained by adhesive is provided. Thus, a limit in design of a magnetic circuit is eliminated, and the performance of a product using it can be enhanced.

Filed: 1986-12-04
Abstract: PURPOSE:To present circumstances where work is effectively advanced, by showing only command which is convenient for a user to know, out of commands which the user does not know and promoting command learning without confusing the user. CONSTITUTION:An inputted command is sent to a command storage means 3 by the instruction of a control means 1 and is stored. Correspondence relations between a certain command and another are described in a relation rule storage means 4. When the user instructs command output by a command output instructing means 5, the control means 1 receives this instruction and a command group in the command storage means 3 is sent to a command comparison output means 6. This means 6 is started by the control means 1 to compare commands in storage means 3 and 4 with each other. Since the command which has never been inputted is outputted in case of coincidence, the user easily finds the new command.

Abstract: PROBLEM TO BE SOLVED: To provide a DRAM (a general-purpose dynamic random-access memory) in which a control signal during the input/output of data can be output to the outside from an input/output terminal. SOLUTION: In a cache DRAM, a DRAM 2 and an SRAM (a high-speed static random-access memory) 4 are integrated in one chip, and the respective memories are controlled by a control circuit 8 and a control circuit 6. In an ordinary operating mode, data from the memory (SRAM) 4 and the memory (DRAM) 2 are output to an output buffer 10 as they are. However, when a signal ϕtm at 'H' is input, a test mode is set, an output circuit 24 degenerates read-out data, and a control signal which controls a memory from which data is not read out is output, via the input/output buffer 10, to an input/output terminal 11 which becomes a surplus.
