Title: Solid-state image pickup device
Inventor: ENDOU YUKIO
IPC: H04N5/335
Filed: 1983-10-18
Abstract: PURPOSE:To eliminate the noises produced from a CCD output circuit by using a sampling circuit which extracts the output signal of an effective signal period directly from the output signal of a clamping circuit and extracts the signal of a reset noise period after converting it into the fixed DC voltage. CONSTITUTION:The DC reproduced signal and the fixed voltage VG are supplied to bases of transistors (TRs) QC and QF respectively. A sampling pulse A having a prescribed bias added by a bias circuit 26 is applied to bases of TRs QA and QB; while a sampling pulse B of the opposite phase to the pulse A is supplied to bases of TRs QB and QD respectively. As a result, each TR of differential pairs is saturated with application of a positive pulse to the base and deflected up to a cut-off state with input of a negative pulse. Therefore a collector current flows with switching every half cycle of the sampling pulse as well as every ON/OFF mode. Thus an effective signal and a part of a stable period are extracted assuredly with an output terminal 27 of a sampling circuit 14. Then a waveform of the voltage fixed by the voltage VG is obtained in a reset noise period as well as at a part of the stable period.

Title: Manufacturing method of cooking appliance
IPC: B21J5/02
Filed: 1992-07-22
Abstract: PURPOSE: To prevent water infiltration in cleaning to eliminate corrosion problem by center matching setting by welding, and forming a sealed part through air removal and permanent deformation by impact compression. CONSTITUTION: A flat metal sheet disk 5, a sheet 3 and a container bottom part 2 are spot-welded 12 at appropriate distances by electric resistance welding at each central part to give resistance against position aberration. Impact compression is applied so as to produce convex curving K in the lid bottom 8. As a result of this forming work, air is forced out from the area between the disk 5 and the lid collar 7 in the impact compression process. During the course or later permanent deformation is generated. This permanent deformation 11 produces a sealed condition by plastic deformation of the sheet material. As a result, the plate material flows to form a collar part 13 in part 11. The gap between the container bottom 2 and the lid 4 no more exists, thereby no water infiltration occurs during use or cleaning, generating no corrosion problem.

Filed: 1993-07-12
Abstract: PURPOSE:To carry out bending of a metallic sheet by linear heating without a skilled engineer. CONSTITUTION:After inputting geometric information on an initial shape and target shape (step 1), the initial shape is mesh splitted by the finite element method (step 2) and the splitted shape is mapped on the target shape (step 3). The initial shape is forcibly elastically deformed in the target shape and the target intrinsic strain in each element is obtained (step 4). The obtained target intrinsic strain is heated by the analogy and the generated intrinsic strain is realized (step 5). A normal relation of heating condition and generated intrinsic strain is obtained so as the generated intrinsic strain is obtained when a heating condition is given (step 6). A work is bent by giving the target shape the generated intrinsic strain by the heating method obtained in the steps 5 and 6 (step 7, 8 and 9). A difference between a working shape and the target shape is required and, if a difference is obtained, the present shape is replaced by the initial shape, the data given to the step 4 are corrected and bending is carried out again (steps 10, 11, 12 and 13).

When the phase is led by one block conversely, the stuff block included already in the multiplexed signal is found out and extracted from the multiplexed signal. Thus, it is possible to synchronize the multiplexed signals. The multiplexed signals are formed to be transmission code constitution in the unit of blocks and the stuff block is used to synchronize the multiplexed signal to simplify the constitution.
