Title: Portable telephone set and radio channel designation method
Inventor: UCHIKURA TAKAO
IPC: H04W76/00
Filed: 1993-03-31
Abstract: PURPOSE:To make dialing through a private radio base station offering less expensive talking charge when the portable telephone set is able to use a public radio base station and the private radio base station. CONSTITUTION:A control section sets a frequency of a 1st control carrier for a private use as an oscillation frequency of a synthesizer (S1). Then whether or not an ID code of a radio base station for a cordless telephone set to which the portable telephone set belongs is detected from the control carrier is discriminated (S2). When the ID code of the radio base station for the cordless telephone set to which the portable telephone set belongs is detected, after the synchronization with the signal transmission of the radio base station, the mode enters the reception standby mode in which the maintenance of synchronization, call reception or dialing is repetitively executed (S7, S8, S9) and respective processing to an event of the call reception or dialing is executed (S15, S16). On the other hand, when no ID code is detected as the result of searching all control carriers for the private use, the frequency of the public control carrier is set to the frequency of the synthesizer (S10) and after the setting of synchronization, the mode enters the reception standby mode.

Title: Monitor switch driving mechanism for microwave oven
Inventor: SATOMI MASAKI
IPC: F24C7/08
Filed: 1979-06-11
Abstract: PURPOSE: To prevent the misaction of the monitor switch of a microwave oven equipped with a safety switch for the energization of a microwave generator, by enabling the movement of a monitor switch lever almost in parallel with that of a latch head.  
     CONSTITUTION: When a door 2 is closed from a full line position to a dotted line position shown in Fig., a latch head 3 moves through a hole 11 to push a monitor switch lever 8 into sliding. As a result, an engaged projection 10 acts to a monitor switch actuator to close a switch 7. When the top hook part of the latch head 3 is engaged with a latch hook 4, a safety switch lever 6 is swung down to close a safety switch 5. The monitor switch is changed over prior to the safety switch when the door is closed. However, the safety switch is changed over prior to the monitor switch when the door is opened. This results in preventing misaction.

CONSTITUTION: An Al alloy material, having a composition consisting of, by weight, 0.3-2% Fe, 0.01-0.6% Mn, 0.01-0.2% Ti, and the balance essentially Al, is cast to 3-10mm plate thickness. by means of casting rolls, followed by process annealing at <=400 deg.C or blue annealing. Then, cold rolling is done to form an Al alloy material for anodic oxidation treatment. Fe and Mn react with Al to form an Al-Fe-Mn intermetallic compound and fall off by means of anodic oxidation treatment. Fine pores, after falling off, trap light, by which a color tone of film between dark gray and blackish dark gray can be obtained. Ti has a function of refining crystalline grains. By reducing cast plate thickness, the intermetallic compound can be formed into film state and also uniformly distributed in large numbers.

Title: Helical vacuum vessel
Inventor: OWADA KORO
IPC: G21B1/00
Filed: 1988-03-30
Abstract: PURPOSE:To prevent generation of restricting stress by a thermal expansion of a helical coil and to avoid generation of stress on a bellows by its torsion, by providing at least one bellows at certain cross sections along a torus direction of a vacuum vessel. CONSTITUTION:When electricity is charged, a helical coil 3 is heated by an electrical resistance of its conductive lead, and expands thermally. On the other hand, an electric current through the helical coil 3 increases, being resulted from generation of a high temperature plasma. Also, the helical coil 3 is being used at higher and higher temperature. An expansion difference between the helical coil 3 and the vacuum vessel is apt to be absorbed by an extension movement of the helical coil 3 sliding along a helical coil groove towards an axial direction of the helical coil. With this movement, the helical coil 3 is apt to expand the vacuum vessel. Therefore, with placement of a bellows at a part of thick wall portion of the helical vacuum vessel, the thermal expansion of the helical coil is not restricted and a thermal stress is not generated.
