Filed: 1989-10-09
Abstract: PURPOSE:To facilitate a looking-at of an interior of an oven housing and eliminate any trouble even if oily smoke is generated by a method wherein a quartz heater is applied and this quartz heater is covered by a uniform heating plate provided with some slits. CONSTITUTION:A quartz heater 10 lights at a color temperature higher than 1,000 deg.C as it is electrically energized and an interior or a cooking housing 6 is illuminated bright with light leaked out of slits 13. In turn, since the quartz heater 10 is almost shielded by a uniform heating plate 14, a light from the quartz heater 10 does not enter directly into an eye (a), resulting in that an interior of the cooking housing 6 may easily be seen and an amount of heat leaked out of the oven through a door 4 is reduced. In addition, a radiation heat with a high radiation intensity got from the quartz heater 10 is received by the uniform heating plate 14 and at the same time it is metered to an appropriate radiation calories with slits 13 and thus the cooked item 9 is uniformly heated with a secondary radiation heat and the convection heat. In addition, the oily smoke dispersed during a cooking operation is almost shielded by the uniform heating plate 14 and merely reaches a surface of a quartz tube 11 through slits 13 only in a quite small amount, so that the quartz tube 11 is not peeled off or cracked due to a phenomenon of loosing sight.

IPC: B23P19/00
Filed: 1985-11-27
Abstract: PURPOSE:To enable the reduction of the occurrence of assembly abnormalities by providing an analyzer for analyzing the frequency of an output signal from a vibration detecting sensor fitted to a part and a discrimination device for discriminating an assembly abnormality on the basis of analysis results. CONSTITUTION:A vibration appearing due to an abnormality at the time of insertion is detected by an acceleration sensor 4. And a signal from the acceleration sensor 4 is decomposed into a magnitude for every component of frequencies by a frequency analyzer 5, where frequencies 'omega1' and 'omega2' are natural frequencies of a part 3 fitted with the acceleration sensor 4. On the basis of results obtained from said analyzer 5, a micro computer 6 makes judgement as to whether or not there is an abnormality in assembly. This judgement is made depending upon whether or not the peak value of the analysis result has exceeded a standard value. In other words, the micro computer 6 judges that there is an abnormality when the peak value has exceeded the standard value, and that no abnormality exists when the value has not exceeded the standard.
