Title: Phs telephone system
Inventor: NAKAI YUKIO
IPC: H04W52/02
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To reduce the current consumption needed for searching a base station, when the radio waves transmitted from the base station cannot be received by setting a waiting state of a base station having its level higher than a reference level and setting the waiting state of a base station having its level lower than the reference level, if the said base station cannot be searched. SOLUTION: A waiting state is set with a waiting zone selection level defined as the receiving level reference value, and accordingly the base stations 2b and 2c are detected in a base station search mode and a waiting state is set at the station 2c having a high receiving level. If the station 2c is not available, the station 2b is detected in a base station search mode and a waiting state is set at the station 2b, having a high receiving level when a waiting state is set with the waiting zone selection level defined as the receiving level reference value. That is, a waiting state can be set at the station 2c having highest receiving level in a waiting state setting mode. Furthermore, a power on period is shortened, when the radio waves of the station 2c cannot be received, and accordingly the current consumption can be reduced.

Abstract: PURPOSE:To enhance the photochemically reactive efficiency for a laser output power by limiting the range of the laser beam passage to a region over the limit fluences of the dissociation reaction of multiple photon in an untreated gas for absorbing an infrared laser beam. CONSTITUTION:The laser beams introduced into a reaction vessel within the allowable fluences of window material, without losing any of their power, pass through a nonabsorbent space chamber 4 free from untreated gas and exceed the limit fluence, reaching a reaction chamber 7 through a separating plate 6 having an infrared ray permeable hole 5. The laser beams brought back within the limit fluence after passage through a plane including a focal point pass similarly through the nonabsorbent space chamber 4 and are brought down within the allowable fluence of the window material, after which they are sent out of the reaction vessel through an outlet window 9. Such laser beams are again converged through a condensing lens and introduced into a second reaction vessel formed similarly to the first mentioned one.

Filed: 1979-06-25
Abstract: PURPOSE:To avoid strain concentration to the jointed part of a lead and prevent it from becoming defective, by protruding the lower part of the lead fitting portion of a resin package along the bending shape of the lead. CONSTITUTION:A projection 8 is made under the lead fitting portion of a resin package 1. A lead is bent along the projection 8.

IPC: H02M7/527
Filed: 1981-05-26
Abstract: PURPOSE:To shortcircuit the slit width of a pulse train by detecting that the ON-pulse width becomes longer than the prescribed value to shortcircuit the ON- pulse at the time of switching a pulse mode. CONSTITUTION:A sinusoidal modulation wave is compared by a triangular carrier as indicated in Figure A, thereby obtainig modulated pulse trains as indicated in Figures B and C. The pulse width of a modulated pulse train is varied by controlling the modulation factor alphaN of the ratio of the pulse trains in Figures B and C, the pulse mode is altered by switching the number of pulses in one cycle, thereby producing an output voltage of variable voltage and variable frequency from a DC voltage. When the fact that the modulation factor alphaN reaches the maximum modulation factor alphamax is detected, the pulse mode is switched to other pulse mode. When the fact that the ON-pulse width T0 of the modulated pulse train width becomes longer than the prescribed value is detected, the ON-pulse is shortcircuited, thereby shortcircuiting the slit width of the modulated pulse train. In this manner, the magnitude of the variation in the step of the modulation factor is reduced, thereby performing a smooth control.
