Title: Video signal processor
Inventor: MATSUYAMA MAKOTO
IPC: H04N9/455
Filed: 1994-08-17
Abstract: PURPOSE: To reduce cost and to miniaturize the device by generating a black burst signal although unnecessitating a dedicated encode circuit by switching, selecting, the blanking term of a composite video signal and a prescribed DC voltage and controlling that switching. CONSTITUTION: A black burst signal generating circuit 32 generates the black burst signal while using the blanking term and DC voltage of the composite video signal outputted from a clamp circuit 30 and a narrow blanking signal equipped with narrower pulse width than the width of the blanking term. This narrow blanking signal is a blanking signal generated by a narrow blanking signal generating circuit 22 based on the blanking signal supplied from a synchronizing signal generating circuit 21. When generating the black burst signal at the border of both the sides of the blanking signal, the switching selection of the selecting terminal of the selector of the black burst signal generating circuit 32 is controlled while using the narrow blanking signal of narrow width.

Title: Semiconductor device
Inventor: TOU KAZUHITO
IPC: H01L23/373
Filed: 1981-11-28
Abstract: PURPOSE:To allow heat radiation of semiconductor elements with different calorific powers by using the same heat radiating mechanism by a method wherein a part of a heat radiating path is constituted of a bimetal resulting in the control of heat radiating amounts. CONSTITUTION:When the semiconductor element 3 is operated, a part of generated heat escapes out to a multi-layer ceramic substrate 1 through solder balls 2, but most of heat is transferred from a part of the bimetal 7 through an arm 6 to a heat radiating fin 4 and emitted. When heat generation becomes large, the heat transferred to the bimetal 7 also becomes large, therefore the curve of the bimetal 7 becomes small, and accordingly the contact area with the semiconductor element 3 becomes large. Thereby, the area of the heat transfer path from the semiconductor element 3 through the bimetal 7 and the arm 6 to the heat radiating fin 4 increases resulting in the increase of heat radiating amounts. If the semiconductor element 3 is overcooled, the curve of the bimetal 7 becomes large, and the contact area with the semiconductor element 3 reduces. Therefore, the heat radiating amount reduces.

Therefore, by providing the dynamic range calculator and re-quantizing device 8 and changing the quantizing step on the basis of the dynamic range, the data quantity can be reduced by hardly spoiling the picture quality.
