Title: Picture distortion correcting circuit
Inventor: KASHIWAGI SHIGERU
IPC: H04N3/23
Filed: 1988-01-25
Abstract: PURPOSE:To freely modulate a horizontal deflection sawtooth current by an aimed waveform with a simple circuit configuration and to correct the shapes of the right and left edges of an image receiving tube raster by surely modulating the horizontal deflection sawtooth current by the same waveform as that of hyperbolic waveform voltage. CONSTITUTION:First, vertical deflection cycle sawtooth voltage Vst from a vertical deflection output circuit 3 is added to a waveform shaping circuit 15. At the waveform shaping circuit 15, the Vst is compressed, and vertical deflection cycle sawtooth voltage Vst' is obtained, in which its inclination is approximately horizontal near the start point of a scanning cycle, becomes steep as the scanning approaches the center of the scanning cycle, and becomes approximately horizontal again when the scanning reaches the end point of the scanning cycle. Thereafter, when the Vst' is added to a next integrating circuit 16, hyperbolic waveform voltage Vhp to satisfactorily approximate to a hyperbolic curve is obtained for the output of the integrating circuit 16. On the other hand, since hyperbolic waveform voltage Vhp' is obtained by synthesizing the Vhp and the Vst at an adder circuit 14, d.c. supply voltage Eb is modulated in accordance with the Vhp' and made into d.c. supply voltage Eb', and the Eb' is made into the operating supply voltage of a horizontal deflection output circuit 1, the p-p value of a horizontal sawtooth current Iyh can be modulated according to an aim.

Title: Package for semiconductor element chip
Inventor: WATANABE KIKUO
IPC: H01L23/02
Filed: 1993-02-01
Abstract: PURPOSE:To reduce the change in element characteristics even when a package is irradiated with ionizing radial rays, such as gamma ray, X-ray, electron beam, by forming a recessed interfacial part with given curvature in an element- chip mounting part. CONSTITUTION:The quantity of an interface trap or a charging center in film caused by irradiation of radial rays depends on stress in SiO2/Si structure, i.e., the deformed quantity at the SiO2/Si interface. The recessed structure of SiO2Si has smaller formation quantity of the interface trap and charging center in film caused by irradiation of radial rays than a projected SiO2/Si structure. Then, a semiconductor element chip is mounted on an element mounting part 1 having a recessed shape with curvature ranging from 0.0001 to 0.001 (1/cm). Moreover, the element mounting part 1 has a conductive lead terminal at its boundary part 2. In this way, the formation quantity of the interface trap or charging center in film by irradiation of radial rays can be reduced.

Title: Optical type object shape measuring device and method
Inventor: KIYONO SATOSHI
IPC: G01B11/245
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To increase measurement accuracy by eliminating all datum error from a measurement result. SOLUTION: A probe 2 is constituted of two displacement meters DS and two angle meters AS. Two displacement meters DS are arranged at a specific position on x axis and at a specific position on y axis and two angle meters AS are arranged on xy coordinates at one side of a straight line connecting the two displacement meters DS with a distance where the ratio to the distance between the displacement meters DS is not an integer. Then, datum error is eliminated from the shape measurement value of a surface to be measured by performing the differential operation processing of the output of each probe 2. Since no zero point of a transfer function obtained by differential operation does not occur at all due to the characteristic arrangement of the two angle meters AS, no shape information is lost due to the differential operation and resolution in vertical direction due to the differential operation improves, thus enhancing a measurement accuracy.
