Title: Motion detection circuit
Inventor: TSUJI TOSHIAKI
IPC: H04N19/87
Filed: 1993-12-22
Abstract: PURPOSE:To enhance the precision of motion detection of a picture signal subject to sub-sampling. CONSTITUTION:A frame memory 1 and a subtractor 2 are used to detect a 1-frame difference signal and a frame memory 21 and a subtractor 22 are used to detect a 2-frame difference signal in a motion detection circuit for MUSE decoder. A motion detection circuit 4 detects a motion of one frame based on the 1-frame difference and an edge signal. A motion detection circuit 5 detects a motion of two-frame based on the 2-frame difference and the edge signal. A widening circuit 8 holds pulses of a scene change signal for 2-frame period and a control circuit 6 controls a motion between two frames based on an output of the circuit 8. A mixer circuit 7 adds a motion of one-frame and a controlled motion of 2-frames to provide an output of a motion signal. Thus, excessive motion at a change in video image scenes is suppressed and the resolution is not deteriorated.

Title: Semiconductor for two-way controlled rectification
Inventor: KATO MINORU
IPC: H01L29/747
Filed: 1987-12-23
Abstract: PURPOSE: To enhance the sensitivity of a gate without imparing the characteristics such as dv/dt breakdown strength and the like, by a constitution, wherein a second electrode, which is connected to fourth and sixth conductor layers in an auxiliary thyristor, is not continuously formed on third and seventh conductor layers, respectively, and the watless current components of both auxiliary thyristors are sufficiently small.  
     CONSTITUTION: When a positive trigger signal is applied to a gate electrode G, carriers are injected into a P-type layer 13 from an N-type layer 16. An auxiliary thyristor comprising the N-type layer 16, the P-type layer 13, an N- type substrate 10 and a P-type layer 19 is turned on. An on current at this time is supplied to a P-type layer 11 as a gate current through a wiring 18. The gate electrode G is connected only to the surface of the P-type 13 in the auxiliary thyristor. The watless component of the gate current becomes very few. For example, the auxiliary thyristor is turned on with the gate current of about several μA. The maximum on current at this time becomes about several hundred mA. Therefore, the main thyristor is sufficiently turned on. The sensitivity of the gate at the time of operation in an I mode becomes very high.

Title: Semiconductor laminated structure
Inventor: ANAMI TAKAYOSHI
IPC: H01L21/20
Filed: 1988-12-23
Abstract: PURPOSE:To lessen the effect of an ionized impurity by a method wherein the energy value of a conduction band lower end in a second semiconductor is small compared with those in first and third semiconductors, the second semiconductor has an in-surface compressive biaxial distortion and at least part of the region of the third semiconductor is doped with an N-type impurity. CONSTITUTION:A conduction band lower end 12 in a high-purity layer 11 is changed as to a laminated direction by a piezoelectric effect due to a distortion even in case there is no internal electric field. This is due to a phenomenon that a III-V compound semiconductor, which is laminated on a substrate consisting of a III-V compound semiconductor and has an in-surface compressive biaxial stress, generates an electric field in the direction identical with the laminated direction. Therefore, a donor type impurity in an electron feeding layer 13 and electrons in the layer 11 result in localizing on an interface 15 on the side reverse to an interface 14 between the layers 13 and 11. Consequently, a spacer layer is not necessary, and furthermore, even if a doping is performed on the layer 13 at a high level and a multitude of electrons are stored in the layer 11, there is little effect of an ionized impurity to the electrons localizing on the interface 15.
