Title: Rubidium atom oscillator
Inventor: ISHIHARA NAOKI
IPC: H01S1/00
Filed: 1989-11-27
Abstract: PURPOSE:To simplify the structure of high voltage spark generation electrodes by comprising a conductor where one party of electrodes is a bracket which supports a rubidium lamp while the other is a conductor which is exposed from its tip and said conductor is coated with an insulation film with the tip fixed with said bracket. CONSTITUTION:A rubidium lamp 2 and the tip of a conductor 4 coated with an insulation film are fixed with a bracket 3. The tip is exposed so that a conductor 5 may be projected, thereby forming a high voltage spark generation electrode with the bracket 3 and the conductor 5. This structure makes it possible to form a simple and low cost high voltage spark generation electrode. Preferably, a non-lighting part 2b of the rubidium lamp 2 is adapted to be wound with the conductor 4, which makes it possible to maintain the temperature of the rubidium lamp during lighting under the optimum condition and hence prolong the lifetime of the rubidium lamp 2, thereby obtaining a high performance rubidium atom oscillator.

Abstract: PROBLEM TO BE SOLVED: To suppress fluctuations in a signal light level of a channel that is continuously transmitted, even in a transient response state by controlling injection current to a stimulation light source so as to maintain a gain from an input and output level of an amplification optical fiber to a prescribed value. SOLUTION: An optical multiplexer 14 multiplexes a one-channel signal light or a wavelength multiplex signal light of a plurality of channels from the left with a stimulated light from a exciting light source 17, the multiplexed light is made incident into an erbium-doped optical fiber EDF 1. An EDF output power detection circuit 4 monitors the sum output between an output resulting from the light made incident onto the erbium-doped optical fiber EDF 1 and optically amplified and an output of the EDF 1, resulting from being reflected in a reflector 9 via a variable attenuator 6 and amplified again via the EDF 1. A variable attenuator control circuit 5 automatically controls the level of an attenuation of the variable attenuator 6, so as to make a sum output power constant. Furthermore, an AGC circuit 3 controls the output of the stimulation light source 17, so that the result of monitor of the circuit 4 makes the gain of optical amplification of the EDF 1 constant. Thus, the signal light received by the optical amplifier amplifies the signal by a scheduled gain.

Title: Semiconductor integrated circuit device and sound powered rfid using this device
Inventor: SAWADA KIKUZO
IPC: G06K19/07
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To eliminate a trouble that built-in ICs are caused to malfunction by an insufficient internal supply voltage generated by using an AC signal supplied from an external source. SOLUTION: A supply voltage for driving built-in ICs and the one for driving the external loads are each separately generated by separately providing an internal driving voltage commutation circuit 1 which generates a supply voltage to drive the built-in ICs and an external driving voltage commutation circuit 2 which generates a supply voltage to drive external loads to be connected with the built-in ICs above. This makes it possible for the supply voltage for driving the built-in ICs not to drop even when the power is consumed to drive the external loads, and thereby prevents the built-in Ics' malfunction by insufficient power caused by driving the external loads.
