Title: Cooking apparatus
Inventor: ISHIKAWA HARUO
IPC: A47J27/00
Filed: 1989-02-28
Abstract: PURPOSE:To decrease the number of parts used, facilitate assembly, reduce man-hours, and achieve low cost by holding a support with possibility of moving vertically, and permitting a lever, which actuates a switch with this vertical motion of the support, to perform restriction of the support for its upward motion. CONSTITUTION:When a pan 1 is set in, a thermo-sensor 6 contacts its bottom, and a support 12 moves downward. The support 12 side of a lever borne moves also downward while its opposite side about the bearing part 17 does upward so as to cause the working surface of the lever 15 to push a switch 19 into actuation, which gives information of the pan 1 being set in to a circuit concerned, and thus thermo-sensing and sensing whether a pan exists are accomplished simultaneously. As the working surface 20 of the lever 15 has resilience, it can be weakened that a thermo-sensitive element 7 is inserted into the backmost, or that a load is applied to the switch 19 due to dispersion in assembly and dimensions, which will prevent poorly finished workmanship in performance of the switch 19. On the other hand, the retaining hole 14 inserting action side of the lever 15 shall be rigid and in the form of a channel so that the thermo-sensitive element 7 is energized by a spring 13 to receive an upward hopout stress, and also the bearing rotation motion of the lever 15 can be made certainly and smoothly.

Title: Plasma display device
Inventor: WATADA KAZUO
IPC: H01J11/42
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To heighten strength and lengthen the service life by forming a dense film on the surface of a partition. SOLUTION: Since a dense film 8 is formed on the surface of a partition 2, the mechanical strength of the partition 2 is high, voids on the surface of the partition 2 are embedded, and release of impurities is suppressed. As the material of the film 8, a mixture of 20 wt.% or more B2 O3 , 18 wt.% or more SiO2 , and 12 wt.% or more Al2 O3 is preferable. B2 O3 acts as glass fusing agent to increase denseness. SiO2 increases surface hardness. Al2 O3 prevents phase splitting of the glass and increases chemical resistance. By including 0.3-10% oxide such as CeO2 , TiO2 or ZnO in the glass forming the film 8, ultraviolet ray shielding action is added, and deterioration of the partition caused by ultraviolet ray can be reduced. The thickness of the film 8 is preferable to be >=3 μm from the standpoint of mechanical strength, chemical resistance and the ultraviolet ray shielding action.

Title: Communication device
Inventor: HONDO JUICHI
IPC: H04N1/32
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To improve the communication quality by raising the transmission level when an inferior receiving state is detected for the receiver of the opposite party side. SOLUTION: The number of the opposite party is dialed and the normal answer of the opposite party is monitored. When a normal answer is received, a communication enable mode is selected and a test is carried out in this mode. When the test result is satisfactory, the actual transfer of information is started. If the test result is unsatisfactory, it is decided whether the transmission trial frequency is lower than a prescribed level. If the trial frequency is lower than the prescribed level, it is decided whether the transmission level can be raised up enough to its upper limit value. If the transmission level can be raised, the value of a variable attenuator 5 is reduced under the control of a CPU 10 and the transmission level is raised. Thereafter, a transmission mode is set again as necessary and the transmission test is repeated.  Then the information is transmitted when the receiving state of the opposite party is improved.
