Patent JP-H0330304-A (JP)
Title: Vibro-isolating supporting device for alternating current electromagnetic apparatus
Inventor: MITSUMATA MASATO
IPC: H01F27/06
Filed: 1989-06-27
Abstract: PURPOSE:To maintain sufficient impact resistance strength even though mass of each electric apparatus is small by installing a plurality of electric apparatuses to a sheet of fitting plate and allowing the fitting plate to be supported on a foundation so as to make its plate vibrationproof through a plurality of springs which are arranged in parallel. CONSTITUTION:A plurality of electric apparatuses 3 are installed on a sheet of fitting plate 2 and the fitting plate is supported on a foundation 1a so as to make its plate vibrationproof through a plurality of springs which are arranged in parallel. Then, all of the electron apparatuses 3 are installed on a common fitting plate 2 and are supported by common springs 4 so as to make the plate vibrationproof. In comparison with the other method where respective electric apparatuses 3 are supported by a separate spring so as to make the plate vibrationproof, the above common plate and springs have an advantage in such a way that even though each spring has the same length, each spring which supports the plate in common makes its sectional area exceedingly larger than that of the spring which is used separately on condition that both methods take the same vibrationproof effect and obtain the same impact resistance strength. Accordingly, there is no possibility of buckling of the springs and the like and its support becomes stable and further, the spring maintains sufficient impact resistance strength as well. Supporting structure keeping a large impact resistance force is thus obtained even though mass of each electric apparatus 3 is small.

Consequently, when a piston 10 starts to go down, the periphery of the cam 35 is fitted to projections 36 and 37 to rotate the eccentric ring 31 clockwise, and the piston body 10 is pushed down. Then, rotating body 20 is prevented from clockwise rotation, and continues to be rotated anticlockwise.

Title: Two/four wire converting system
Inventor: SUKAI TSUNEHISA
IPC: H01L27/102
Filed: 1983-09-08
Abstract: PURPOSE:To attain conversion without increasing the number of processing bits by using an AD converter of logarithmic scale type with minimum quantized noise to attain automatic gain control. CONSTITUTION:Logarithmic value of an output digital value corresponding to an input analog value is proportional to the analog value in the AD converter A/D. The output of the A/D addresses a read only memory ROM. The content of recording is decided so that the logarithmic value of the address value is proportional to the output value in the memory ROM. The quantized noise of the A/D output is not increased in an analog minute signal. The ROM output value is multiplied with an output of a T2 by an X in an AGC block and the result is outputted to an OUT terminal at a proper level. The processing of the operating formula is performed in the processing block at the OUT terminal and succeeding by dividing 3rd and 4th bits at the low-order of the preceding block output logical value. Then the filter coefficient is adjusted in a direction where the absolute value of the transmission/reception correlation approaches zero.

IPC: H01L23/50
Filed: 1992-06-24
Abstract: PURPOSE:To obtain a package structure for an electronic component having a QFP structure that can meat high density packaging with an improved positional accuracy of a lead. CONSTITUTION:A ring-shaped insulated tiebar 2 is disposed close to the root of connecting leads 1a projecting out of a package molded with resin 4. An insulated intermediate frame 5 is disposed on the outer edges of the leads. A package having a QFP structure is obtained by bending the leads between the tiebar 2 and the frame 5. To facilitate the bending of the leads on the four sides of the package and make connecting portions of the leads flush with each other, four corners of the frame 5 are removed, or the corners are complemented with a part of an outer frame of the lead. This makes it possible to reduce variations in positional accuracy of the leads to substantially zero, and hence failures to connect to a printed board can be reduced to a much greater extent.
