IPC: H01L23/50
Filed: 1981-11-02
Abstract: PURPOSE:To eliminate the floating and lateral displacement of a tab lead by forming a strain absorbing hole at a part of the tab lead forming a lead frame, thereby absorbing the thermal strain produced at the resin sealing time by the deformation of the hole. CONSTITUTION:Parallel leads 4 are formed via a dam 4 for preventing the resin flow between parallel outer frames at both sides of the lead frame 1, and a plurality of leads are projected from the leads 4 toward the tab 5 of the supporting member for placing a semiconductor element 6 disposed between two leads 4. When the tab 5 disposed between the leads is supported by the tab leads 8, 8' bridged between the outer frames, strain absorbing holes 9, 9' are formed at the positions where the leads 8, 8' approaching the outer frames. That is, the holes 9, 9' are annularly formed at the branches A, A'. Thus, the thermal strain caused at the time of sealing the element 6 with resin can be absorbed by the deformation of the holes 9, 9', and floating and displacement do not occur at the leads, 8, 8'.

Title: Heating cooker
Inventor: KONDO TOMOYUKI
IPC: H05B6/68
Filed: 1991-07-16
Abstract: PURPOSE:To procure reference data indicating zero point, even when a power supply is interrupted, and to prevent degradation of reliability of non-volatile memory. CONSTITUTION:Supplied with power, a microcomputer 1 reads out a reference data from an EEPROM 10, stores it temporarily as a zero point indicating data, and detects a weight of a placed matter based on a frequency signal from a weight sensor 8 with reference to the reference data. At a time of cooking, a zero point is adjusted corresponding to a variation of the zero point of the weight sensor 8, and then the zero point newly adjusted is stored temporarily. If power supply is interrupted, it is detected, and the reference data at that time is rewritten into the EEPROM 10 by extra voltage of a power source circuit. Thus, frequency of rewriting of the reference data is minimized and reliability is improved.
