IPC: H05B6/68
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To enable an actual temperature measurement of an article to be heated in a heating chamber even under a demonstration mode, and perform a demonstration having a persuasion power at a store by a method wherein this microwave oven is allowed to enter a demonstration mode while keeping a magnetron under a non-active state, and an infrared sensor is operated under the demonstration mode. SOLUTION: During a demonstration mode, a relay 17 is always kept under an open state, regardless of the operation of a keyboard 26 so that a magnetron may be not energized. Then, a relay 20 for a chopper motor 19 is closed, and the chopper motor 19 starts the operation. By this motion, an infrared ray from an article to be heated for a demonstration intermittently enters an infrared sensor 11 through a chopper which is rotated by the chopper motor 19, and the temperature of the article to be heated is measured. The measured temperature is shown to a user (salesperson) and patrons by a display tube of a display panel. Therefore, at a store, a demonstration having a persuasion power can be performed for patrons.

Abstract: PURPOSE: To appropriately detect the hydrogen embrittlement of a pressure pipe, by eliminating the adverse effect of residual compressive stress remaining at the tip of a crack.  
     CONSTITUTION: A notch 2 is provided on an arc-shaped test piece 1. The center 3 of the outside surface and both the ends 4 of the inside surface of the test piece are repeatedly pushed for three-point bending while the test piece is supported at the center 3 and both the ends 4. Thereby, a fatigue crack 5 is produced in the test piece. The test piece is inserted into a pressure-pipe-type heavy water reactor. At the time required, the test piece 1 is picked out of the reactor. The three-point bending of the test piece supported at the three points 3, 4 is repeated so that the fatigue crack is enlarged and the tip of the crack goes far awary from the residual compressive stress 7 remaining at the preceding tip of the crack. Thereafter, a load on the test piece 1 is statically increased so that the test piece is fractured. Then, the fracture toughness of the test piece is determined.

Unlike conventional recording media of a similar type, said recording medium does not contain any color-producing adhuvant that generates an alkali, and the recording layer is maintained in an acidic atmosphere by the acidic coupler and the acid stabilizer. Accordingly, said recording medium is excellent in preservation stability and favorable in sensitivity of heat-sensitive color-producing property.

Title: Reproducer for rotary recording medium
Inventor: SHICHIJIYOU SHIYUNICHI
IPC: G11B20/18
Filed: 1983-01-31
Abstract: PURPOSE:To attain a so-called interactive mode reproduction between an external device by synthesizing in time series a sound signal recorded together with a video signal or reproducing a disk which recorded a control program in a limited band in place of the sound signal. CONSTITUTION:The control program signal taken out of a control program generator 15 is modulated by a modulator 19 in a self-clockable modulating system such as an FM (frequency modulation biphase space modulation) system. This modulated signal is limited to a sound signal band by an LPF20 and at the same time delayed by about 1H to be turned into a waveform of almost a sine wave. For the output signal of the LPF20, the phase of its peak value corresponds approximately to the phase of a horizontal synchronizing signal. Therefore, the data can be demodulated with use of the reproduction output of the horizontal synchronizing signal without reproducing a clock component out of the horizontal synchronizing signal.
