Title: High frequency heating cooking utensil
Inventor: YAMASHITA KAZUO
IPC: F24C1/02
Filed: 1990-05-17
Abstract: PURPOSE:To obtain prompt heating performance, high temperature radiation, reduce cooking time and scorch food to be cooked more easily by holding a sheet-like heating element with a sustaining device, and allowing the greater part of the heating element to be located into a space. CONSTITUTION:To prevent the penetration of high frequency, it is acceptable to specify the maximum diameter for a through hole for a high frequency shielding board 3 as 5mm and smaller. A sustaining device 5 comprises a rod-shaped member 5a made of heat-resistant glass, and a bonding member 5b which bonds a metal heating element 6 with the rod-shaped member 5a. A sheet-like heating element 4 is a metal heating element made of stainless steel, nickel, chrome, and the like, which is laid out in a zigzag manner. This sheet-like heating element 4 is supported by the sustaining device 5. Moreover, a contact area between the sheet-like heating element 4 and the sustaining device 5 is small, which minimizes thermal diffusion induced by thermal conduction and forces the sheet-like heating element to reach high temperature in a short time by the application of electric power. This high temperature-induced radiation passes through the penetration hole of the high frequency shielding board 3 and directly heats up a heated substance. It is, therefore, possible to reduce cooking time and scorch the heated substance more easily.

Title: Television receiver
Inventor: SOMEYA KAORU
IPC: H04N5/21
Filed: 1994-06-09
Abstract: PURPOSE:To eliminate the signal component of an adjacent channel by adding the output signal through a band pass filter receiving an IF signal with a delay time and a signal resulting from attenuating the IF signal and setting properly the delay time. CONSTITUTION:A SAW filter 1 receives an IF signal from a tuner and gives an output to an adder 32. The phase characteristic of the input and output depends on the shape of an input transducer 1a and an output transducer 1b and the distance between them and its group delay time is made flat. An attenuation circuit 31 attenuates an IF signal from the tuner at a preset attenuation rate and gives the attenuated signal to the adder 32. The delay time T of the SAW filter 1 is set so that a relation of omegaT=pi+2npi (n = integer) is satisfied for the delay time T of the SAW filter 1 at frequency positions between a video carrier frequency and an audio carrier frequency of adjacent channel thereby making the input and the output opposite in phase to each other. The attenuation rate of the attenuation circuit 31 is set corresponding to the attenuation rate of the SAW filter 1 to eliminate the signal component of the adjacent channel.

Abstract: PURPOSE:To protect a CMOSFET from destruction or deterioration by a method wherein a P well is diffused just above a P<+> layer imbedded in an N<-> epitaxial layer on an N<+> substrate. CONSTITUTION:An N<-> epitaxial layer 23 is constituted by imbedding a P<+> layer 22 in an N<+> type Si substrate 21. A P well 2 is diffused from a position opposed to the P<+> layer 22, causing diffusion from the N<+> substrate 21 and the P<+> well 22. The N<-> layer 23 at the bottom of the well 22 is mostly converted to a P<+> layer 24 and, in areas other than the well 22, an N<+> layer 25 is formed. A regular well 2a and an N<-> layer 23a with a depth of approximately 5mu remain on the surface of the N<+> layer 25. Then N<+> layers 3 and 4 as well as P<+> layers 5 and 6 are selectively provided as predetermined. This constitution results in a substantially deeper well 2 with higher depant concentration that greatly increases the current needed to cause a secondary breakdown, thereby improving device characteristics of surviving destruction or deterioration.
