Title: High pressure sodium lamp
Inventor: ITOU AKIRA
IPC: H01J61/26
Filed: 1982-02-10
Abstract: PURPOSE:To make a barium getter which has an excellent electron-discharging property to hardly become an electrode for outer-tube electric discharge by insulatingly supporting a getter principally consisting of barium in an outer tube. CONSTITUTION:In a high pressure sodium lamp, inside of an outer tube 1 is maintained highly vacuum, and a barium getter ring 17 is fixed to a stem glass 4 through a strut 15. As a result, the getter 17 has an electric potential, that is to say, it is electrically insulated, and no high voltage pulses are applied to the getter 17 during the starting of the lamp. Although barium (Ba) tends to easily trigger electric discharge since it has an excellent electron-discharging property, no electric discharge is induced since the barium getter 17 is electrically insulated as mentioned above, and outer-tube electric discharge hardly develops. As a result, even when the internal atmosphere of the outer tube 1 comes to easily cause outer-tube electric discharge due to high voltage pulses applied to the internal atmosphere when mercury, sodium or Xe gas leaks out of an emission tube 2 into the outer tube 1, any outer-tube electric discharge which might be caused due to the getter 17 is prevented.

Title: Modulator
Inventor: HIROSE TOSHIYUKI
IPC: H03C3/00
Filed: 1981-02-16
Abstract: PURPOSE:To obtain excellent modulation characteristics by allowing the phase variation of an oscillation modulator for a microwave band to follow up that of an intermediate frequency oscillator. CONSTITUTION:A frequency-modulated input signal from a modulated-signal input terminal 2 is converted into an FM wave by an intermediate frequency oscillating modulator 11. Its frequency is applied to a phase comparator 12, whose output is applied to a microwave oscillating modulator 14. The output of the modulator 14 while sent out via a microwave output terminal 4 is branched and frequency-converted by a frequency converter 15 to apply an intermediate frequency to the comparator 12. This constitution has a phase synchronizing loop and the phase variation of the modulator 14 for a microwave band in the phase synchronizing loop follows up that of the modulator 11. Thus, modulation characteristics are improved by the loop gain of a phase synchronizing loop system to maintain the excellent modulation characteristics of the modulator 11.

Title: Follow-up type gyroscope device
Inventor: FURUYA MAMORU
IPC: G01C19/30
Filed: 1981-02-16
Abstract: PURPOSE:To reduce cross coupling by a simple and inexpensive constitution, by providing a ferromagnetic substance on a production of a rotating shaft of a rotor of a follow-up type gyroscope. CONSTITUTION:An iron piece 6 is fixed onto a base 5 being on an extension of a rotating shaft 2 of a rotor 1. When the rotating shaft 2 of the rotor 1 has deflection angle against the cylindrical center shaft of a coil 4, a relative distance between the iron piece 6 and both N and S poles of the rotor 1 is varied, synchronizing with rotation of the rotor 1. Since the rotor 1 is rotated around the rotating shaft 2 at a high speed, a perturbation movement is generated in the right angle direction against mean attraction force, by attraction force of both the poles of the rotor 1 and the iron piece 6, and its direction is reverse to that of cross coupling caused by inductance of the coil 4. In this way, cross coupling is reduced by a simple and inexpensive constitution.

CONSTITUTION:When recording paper A is manually supplied by a paper feeder 1, the recording paper A is mounted onto a mounting bed 14 by lowering a lift plate 17, and a point end part of the recording paper A is introduced onto the lift plate 17. While a cam 21 of a turning mechanism 22 is rotated lifting the second arm 20.

On the contrary, when the paper feeder 1 is not used in case of performing an automatic paper feed or the like, the second arm 20 is lowered by rotating the cam 21, and a point end part of the lift plate 17 is lowered by releasing urging force by the spring member 19.

When regeneration of exciting energy ends at time T2 , the main switch element 27 is turned on and the operation is repeated. According to the arrangement, exciting energy can be regenerated from to the input power supply 1 and a DC/DC converter having high power conversion efficiency can be realized.
