摘要： PROBLEM TO BE SOLVED: To realize an operation panel molded in two layers of a decorative film and a resin, which is prevented from deforming by bimetal effect in molding or heating, and has a high-class feeling never attained in the past. SOLUTION: A decorative film 8 is sandwiched with resin layers, and a transparent layer is provided also on the surface of the film, whereby an operation panel of three-layer structure is formed. The drawing caused by the contraction of a rib or boss part provided on the reverse side in molding is solved, and the transparent layer from the printed surface to the panel surface can be thickened. Accordingly, an operation panel having a higher-class feeling than in the past can be realized, and the yield in molding can be improved, and the thermal contraction between the films can be suppressed. The number of part items such as a fitting claw 11, a tape, or the like, can be reduced. In an operation button part 5, an elastically deformable emboss 12 is integrally molded with the operation panel.

摘要： PROBLEM TO BE SOLVED: To improve heat efficiency by forming a heat conducting layer on the inside of an inner pot, and setting the heating layer on the outside to the thickness specific times the current infiltration depth of a magnetic material or above. SOLUTION: An inner pot 36 is provided with a heat conducting layer 36A on the inside and a heating layer 36B on the outside, the heating layer 36B made of a magnetic material is set to about 2.5 times the peculiar current infiltration thickness of a magnetic material or above in machining, and the heating layer 36B can be sufficiently secured. It is known that the heat efficiency is improved as the thickness (t) is increased and energy saving can be realized based on the current quantity It to the depth (t) from the surface obtained from equations I, II and the effective current ratio S at the thickness (t) obtained from equations III, IV. The heating layer 36B is made of 430 stainless steel with the thickness of 0.8mm, and the current infiltration depth δ of the 430 stainless steel is δ=0.28mm at the frequency of 20kHz. When efficiency is calculated, S=94.26% is obtained from the equations I-IV. In comparison with the inner pot 36 having the thickness of 0.55mm, the efficiency for the thickness of 0.55mm is S=85.97%, and efficiency is improved by 8.29%.

摘要： PURPOSE:To improve S/N characteristics by using a semiconductor laser element which emits a signal light intensity-modulated by an additional signal of a frequency lower than that representing a spectral beam width of an output laser light in addition to an analog electric signal of a RF band to an optical fiber as a signal light source. CONSTITUTION:An analog optical transmitter comprises a signal semiconductor laser element 3 for emitting a signal light intensity-modulated by an analog electric signal 21 of an RF band, an optical fiber 4 for transmitting the signal light emitted from the element 3, and a photodetector 5 for converting the signal light transmitted through the fiber 4 into an electric signal. The element 3 has a configuration for emitting a signal light further intensity-modulated by an additional signal 22 of a frequency lower than that representing a spectral beam width of the element 3 to the fiber 4. Thus, interaction noise generated by multiple reflections is reduced, and S/N characteristics are improved.

摘要： PURPOSE:To obtain short wavelength laser beam pulses having a high output and in a very short time by conducting mode locking by TM mode oscillation and coupling beam pulses with an optical guide type wave-length changing element. CONSTITUTION:Currents are injected to the active layer 10 of a semiconductor laser 16 from a power supply 38. Laser beams 40 emitted from a first end face 14 on which an antireflection film 15 is shaped are passed through a lens 42, a polarizer 44, through which only a TM polarizing component is passed, and an etalon 46 as a wave-length controller, and reflected by an external reflector 22 and fed back to the semiconductor laser 16. When inrush currents are modulated by the round trip frequency f=2L/C (in formula, C represents light velocity and L a distance between the end face 12 of the laser 16 and the reflector 22) of an external resonator, beam pulses 48 for a time (1ps or less) shorter than conventional devices are acquired. It is because the residual reflectivity of the antireflection film 18 is reduced at a TM mode. The beam pulses can be coupled directly with a wave changing element, thus acquiring short wave-length pulses having a high output.
