Title: Video camera
Inventor: FUJIWARA AKIHIRO
IPC: H04N5/232
Filed: 1989-12-20
Abstract: PURPOSE:To improve the focus state detecting performance in the lens driving direction and at the same time to compensate the visual deterioration of pictures via a noise eliminating circuit by improving the sensitivity detected to the subjects under the inferior conditions such as the low luminance, a low contrast. CONSTITUTION:When a focus lens 1 is set in a back focus state, the output voltage change of a peak holding circuit 9 has the same phase to the modulation signal produced with oscillation of an image pickup element 3. Meanwhile the output voltage change of the circuit 9 has an opposite phase with a front focus state of the lens 1. In addition, the voltage corresponding to a detected waveform is obtained in an in-focus state. Thus it is possible to decide the front focus state, the back focus state, or the in-focus state. Based on this working principle, the control signal outputted from a system control signal 11 is converted into the analog value via a D/A converter 16 and supplied to a driving circuit 15 of a vibration element 14. Thus the amplitude and the vibration cycle of the element 14 are controlled. Furthermore a noise eliminating circuit 6 is provided so that the picture signals are accumulated and the noise component is suppressed.

Title: Die-attaching material for ceramic package
Inventor: AOKI MASATAKA
IPC: H01L21/52
Filed: 1987-12-27
Abstract: PURPOSE:To improve bonding strength of a semiconductor pellet, to be resistant to a processing condition in a posterior process and to maintain high reliability by a method wherein graphite is used as a filler for noncrystalline glass of a specific kind. CONSTITUTION:A range of 5 to 20 weight parts of graphite is added to 100 weight parts of noncrystalline glass composed of an oxide of Pb, B and Si. The graphite used as a filler in this case has excellent cleavability; it acts to absorb a stress in a noncrystalline glass part to be generated due to contraction during a cooling operation in a process where a die-attaching material is bonded and fixed to a substrate in a cavity part of a ceramic package; it forms a bonding layer having no internal strain. Accordingly, a strain due to a bonding operation of a semiconductor pellet is reduced; as a result, excellent bonding strength is realized. If a range to be added of the graphite is less than 5 weight parts, its effect is not clear; if the range exceeds 20 weight parts, a drawback that the graphite is oxidized to generate an air bubble is revealed.
