Title: Automatic parity error restoring method for parity check circuit of eprom
Inventor: SASAKI ATSUSHI
IPC: G06F11/10
Filed: 1990-11-27
Abstract: PURPOSE:To eliminate the factor of a parity error and to improve the reliability of a parity check circuit by using the check sum produced from the parity check data. CONSTITUTION:The check sum data is obtained from the parity check data written previously in a read/write enable memory 8 and then written in a check sum memory 20. When a parity error occurs, the check sum data is obtained from the contents of the memory 8 and compared with the contents of the memory 20. Thus it is decided whether the parity check data of the memory 8 or the contents of a program EPROM 2 are changed. Then the parity error caused by the bit change of the parity check data is automatically restored. As a result, the factor of the parity error is eliminated and the hardware reliability is improved for a parity check circuit.

Title: Packaging method of semiconductor device and semiconductor device assembly
Inventor: TANIGUCHI YOSHIKUNI
IPC: H01L21/52
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To provide a packaging method of a semiconductor device and a semiconductor device assembly capable of improving productivity, facilitating the management of a manufacturing process, and realizing high reliability in connection. SOLUTION: An electron-beam cure resin 16 is filled between a semiconductor chip 10 and a wiring substrate 12 and is irradiated with an electron beam. The electron beam passes through the semiconductor chip 10 to cure the electron-beam cure resin 16 under the semiconductor chip 10. Since the electron- beam cure resin 16 does not contain a reaction starting agent or a reaction promoting agent and resists deteriorating, it is easy to manage a manufacturing process. Since the electron-beam cure resin 16 is cured in a short time, it is possible to realize an in-line production. The electron-beam cure resin 16 does not produce a residual stress after it is cured and the resin 16 between the semiconductor chip 10 and the wiring substrate 12 is also cured, that is, so-called underfill resin curing can be realized.

Title: Radar antenna
Inventor: SHINONAGA MITSUYOSHI
IPC: G01S7/36
Filed: 1992-12-03
Abstract: PURPOSE:To cope with interference in the side lobe direction in a wide range by canceling an arriving wave component in the side lobe direction of a main antenna by means of a receiving signal of an auxiliary antenna. CONSTITUTION:A factor generator 32 inputs a receiving signal for each system fed to an elevation angle (EL) synthesizing part 13 for a main antenna 1 to discriminate a side lobe of the main antenna 1 and generates factors w1-wm for suppression thereof. It multiplies (311-31m) digital receiving signals of an auxiliary antenna 2 distributed to an (m) system by corresponding factors w1-wm respectively, and subtracts (331-33m) them from corresponding azimuth (A) synthesized output (sub-array output) of the main antenna 1 to operate a side lobe canceler 3 for each system. With this constitution, since a gain required for the auxiliary antenna 2 becomes 1/m, the simple auxiliary antenna 2 can cover a wide range. Thereafter, EL synthesizing can secure a gain of the main antenna 1.

Filed: 1993-12-22
Abstract: PURPOSE:To provide a very small vacuum tube corresponding to compactness whose electric field emitting efficiency is high and characteristics are uniform without dispersion by a manufacturing method of high yield and high producibility.
