IPC: H01L23/50
Filed: 1992-12-18
Abstract: PURPOSE: To make a semiconductor package thin and small-sized as a whole by molding the package, so that one end part of an internal lead is exposed. CONSTITUTION: An internal lead 12 is bent several times in a package, and an external lead 17 is extended to the internal lead 12, connected to a wire, and exposed to outside the package. Insulating tapes 13 are adhered onto respective end parts 12a of the internal leads 12 for preventing the internal leads 12 from flowing and maintaining intervals of the internal leads 12. A package 16 is molded out of resin around a chip 14 and holds the chip 14 and a wire 15. Package molding is performed so that a specific thickness of an end part 12a of the internal lead 12 is partially exposed to outside the package 16. Consequently, direct fitting to a circuit pattern formed on a substrate 18 is made possible, by utilizing the end part 12a of the internal lead 12 and the mount height is reducible.

Title: Feroelectronic substance fatigue fife testing method and testing device
Inventor: FUKURODA JIYUNJI
IPC: G01N27/60
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To perform a fatigue life test in a short time even in a ferroelectric material with a long reversing fatigue life so as to easily predict a fatigue life of the material by regressing a function of reduction ratio of a residual polarization value of the material by a straight line as a function of a reversing frequency of polarization reversing pulse and extrapolating the straight line so as to predict a fatigue life of the material. SOLUTION: After polarization reversing pulse voltages, which are N in number, are impressed between the electrodes of a capacitor 1 formed of ferroelectric material, a residual polarization value Q is measured, and this measurement is repeated while increasing the reversing number N gradually. These measurement results are plotted as a function of a reduction ratio of a residual polarization value Q while using a lateral axis for a logarithm of the reversing number N and using a vertical axis for the reduction ratio of the vesidual polarization value Q. Using the obtained regressing line, a polarization reversing life of the ferroelectric material can be predicted. For example, a life for the residual polarization value Q with a reduction ratio of 20% can be easily predicted on the basis of the data for a far lower reduction ratio of the value Q.  Therefore, a life can be predicted by means of the measurement in a short time.

Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To provide a rotary drum device allowing to precisely set a gap between a stator and a rotor of a rotary transformer for signal transmission with a simple structure. SOLUTION: The accuracy of a gap σ between a rotor 6 and a stator 7 of a rotary transformer depends on an assembling accuracy of the rotor 6 on a rotary upper drum 3. A plane part 6b of the rotor 6 directly abuts on an abutting plane provided on a part of the structure of the upper drum 3. Mounting and fixing of the rotor 6 onto the drum 3 are done by tightening the cylindrical mounting surface 3a coaxial with the upper drum 3 and the inner peripheral surface 27a of a member 27 supporting the rotor fitted thereon with vis 25. Here, since the accuracy of the member 27 has no influence on the gap σ, it can be a resin-molded part.

Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To obtain the stable operation of a desulturizing device by accelerating the oxidation and neutralization reaction of an absorbent solution and preventing the settling of the solid such as gypsum by eliminating the dead space of slurry agitation at a rectangular liquid reservoir. SOLUTION: The flow for sweeping the absorbent solution to the direction from a slurry agitator 11 to a discharge piping 12 of a circulation pump 6 is generated and moreover the solution is made to flow to the circulation pump 6 direction by the draw-in force resulted from the suction of the solution by the circulation pump 6 by arranging the slurry agitator 11 at the position at which the sweeping direction of the absorbent solution from the agitator 11 is placed oppositly to a discharge piping 12 of the circulation pump at the liquid reservoir 7 provided at the lower part of a absorption tower body 1 having a rectangular horizontal section. Therefore, a dwelling part of the solution is hardly caused at the liquid reservoir 7, especially bottom part, and the solid matter such as gypsum is hardly caused.  In such a way, the pH of the absorbent solution becomes liable to recover since the retention time of the limestone supplied to the liquid reservoir 7 at the liquid reservoir 7 is increased.

Title: Digital signal detecting circuit
Inventor: TOGASHI SHIGEKAZU
IPC: H04L25/03
Filed: 1989-12-29
Abstract: PURPOSE:To prevent the occurrence of the differentiating action on a crosstalk signal due to quantitization feedback by adding a second zero crossing detecting means to a detecting circuit to detect a crosstalk component and feeding back its low frequency component also through a high band cut-off means. CONSTITUTION:A main signal is detected from the input signal, where crosstalk is synthesized with the main signal, by a first zero crossing detecting means 3, and the main signal is subtracted from the input signal of the first zero crossing detecting means 3 to detect the crosstalk signal by a second zero crossing detecting means 5, and the output of this means 5 is detected with the same level as the input signal by an automatic gain control means 6, and it is fed back through a high band cut-off means 8 after being added to the main signal detected by the first zero crossing detecting means 3. Consequently, the crosstalk signal is detected also by the second zero crossing detecting means 5, and its low band signal component is correctly fed back through the high band cut-off means 8. Thus, the main signal is prevented from being degraded by a disturbance signal due to the differential waveform of the crosstalk signal.
