Title: High frequency heater
Inventor: HISHIYAMA KOJI
IPC: H05B6/68
Filed: 1990-08-20
Abstract: PURPOSE:To prevent generation of destruction caused by an over-current of semiconductor switching element and explosion noise at that time by inserting fuse resistance into a control circuit of high frequency heater, and fusing it when abnormal condition occurs in the control circuit. CONSTITUTION:A control circuit is provided with a fuse resistance 30. If abnor mal condition such as moding in a magnetron 9 or short-circuiting in primary or secondary parts of a transformer 3 is generated, an over-current flows to a base from a collector of semiconductor switching element 5 and further to a fuse resistance 30 via an emitter of semiconductor element 31, the collector, etc., to fuse the resistance 30. It is thus possible to prevent destruction of the element 5 caused by an over-current and generation of explosion.

Title: Solid-state image pickup device
Inventor: YONEMOTO KAZUYA
IPC: H04N5/374
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To enable improvement with respect to degradation in sensitivity linearity of pixel output at the time of small signals and fixed pattern noise by forming the distribution of potential that facilitates the accumulation of signal charges and the passage of surface channel current into one and the same place. SOLUTION: The potential under the element isolation gate electrode 26 around a pixel 21 is gradually reduced from the surface to the depth of overflow barrier to prevent signal charges 8 and channel current 11 from leaking to adjoining pixels 21. This facilitates the accumulation of the signal charges and the passage of the channel current at the center of the gate of the pixel 21 because of the two-dimensional effect of the potential at the element isolation gages. This structure causes a slight undulation to be produced in the potential distribution within the pixel due to the effects of interface state density and the like.  Even if the undulation varies from one pixel to another, therefore, the degradation in the linearity of sensitivity is not caused, when there are no sufficient signal charges, and it is possible to reduce the fixed pattern noise due to variation between the pixels.
