Title: Rubidium atom oscillator
Inventor: FUKUKAWA SHINICHI
IPC: H03L7/26
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To enhance frequency stability by comparing the output of a photoelectric converter with a preset reference voltage and controlling heating of a rubidium lamp by a heater depending a difference thereby making the luminous quantity of the rubidium lamp stable. SOLUTION: When the temperature of a rubidium lamp 7 is decreased, the output of a photoelectric converter 12 is decreased and the output of an amplifier 2. Then a reference voltage and an input voltage of a temperature controller 13 have a difference and the current to a heater 9 is controlled based on the difference. When the current to the heater 9 is controlled based on the difference, the temperature of the heater 9 rises and the temperature of the rubidium lamp 7 in a lamp exciter 5 rises. Conversely, when the temperature of the rubidium lamp 7 rises, the output of the amplifier 2 is increased and a difference is produced between a reference voltage and the input voltage of the temperature controller 13.  Based on the difference, when the current to the heater 9 is controlled, the temperature of the heater 9 is reduced to reduce the temperature of the rubidium lamp 7 in the lamp exciter 5.

Abstract: PURPOSE:To enable the discharge volume of NOX to be reduced by providing a vacuum switch for opening a solenoid valve in a vacuum passage of a vacuum lead angle when the operating vacuum of an EGR valve is low, in a device for controlling the ignition time by actuating the vacuum lead angle device. CONSTITUTION:Vacuum pressure from a vacuum port 10 is directly applied into a vacuum operating chamber 7a in a low speed range in which a thermo-valve 14 is closed, a vehicle speed switch 17 is closed and a solenoid valve 13 is also closed after warming-up operation, and therefore, the opening degree of an EGR valve increases. At this stage, a solenoid valve 29 is closed due to contacts 30b in a vacuum switch 30 being opened, and therefore vacuum pressure from a vacuum port 23 is directly applied into a vacuum chamber 22 in a vacuum lead angle 22 so that lead angle is carried out. Then, the opening degree of the EGR valve 7 decreases during an intermediate or high speed range in which the vehicle speed switch 17 is closed and the solenoid valve is opened for communicating a vacuum passage 12 with an atmospheric port 16, and therefore, the contacts 30b of the vacuum switch 30 are closed for changing the position of the solenoid valve 29 into the atmospheric side, thereby the degree of the vacuum lead angle device 22 decreases.

Abstract: PROBLEM TO BE SOLVED: To prevent a pressure loss of fluid by arranging a leak passage connecting one of fluid passages on the upstream side and downstream side beyond a heat exchanger to the inside of a pressure regulation chamber via a narrow cross sectional area and a constant differential pressure control valve controlling a differential pressure between a fluid pressure inside the other passage and a fluid pressure inside the pressure regulation chamber at an optional constant pressure. SOLUTION: In fluid passages 1 on the upstream side and the downstream side beyond a heat exchanger 2, a downstream side passage 1b is connected to the inside of a pressure regulation chamber 13 by a leak passage 17 via a narrow cross sectional area. An upstream side passage 1a is connected to the pressure regulation chamber 13 by a pilot flow passage 3, and in the middle of the pilot flow passage 3, a constant differential pressure control valve 20 is inserted and connected in series. The pilot flow passage 3 is formed so as to be provided with a cross sectional area greatly larger than that of the leak passage 13. The constant differential pressure control valve 20 controls a differential pressure between a fluid pressure on the upstream side beyond the heat exchanger 2 and a fluid pressure inside the pressure regulation chamber 13.  In this way, a pressure loss inevitably generated by the heat exchanger 2 can be used for operating a main valve 11.

Abstract: PROBLEM TO BE SOLVED: To automatically perform opening operation while preventing a movable unit from being opened suddenly by providing a camera with a resistance means imparting resistance to the operation of the movable unit by the energizing force of an energizing means. SOLUTION: While the locking of the movable unit (barrier) 2 in a closed state is released and the barrier 2 is shifted to an opened state by the energizing force of a spring 7, a coupling string 10 being a resistance means winds round the base part of the guide groove 11a of a fixed shaft 11 as the barrier 2 is rotated with respect to the fixed shaft 11. A take-up gear 9 is rotated clockwise by an amount equivalent to the coupling string 10's winding round the shaft 11, but the rotational resistance of a damper 8 is imparted to the rotation through intermediate gears 16 and 17. Therefore, the opening operation of the damper 8 is gently performed so as to prevent a hinge 4 from being broken and a camera main body from being broken by the sudden operation of the barrier 2.
