Title: Low pressure mercury vapor electric discharge lamp
Inventor: ITO HIDENORI
IPC: C03C17/34
Filed: 1991-01-30
Abstract: PURPOSE:To prevent early blackening of the surface of a phosphor by using, as a surface layer, a layer whose contact charge order is relatively on the positive side out of plural layers of film. CONSTITUTION:In a low pressure mercury vapor discharge lamp in which a fluorescent film 2 consisting of a plurality of layers is formed on the inside of a glass bulb 1, the fluorescent film 2 which is charged relatively negative is defined as a lower layer 21, and the fluorescent film 2 which is charged relatively positive is defined as a surface layer 22. A film surface layer portion, therefore, tends to display its relatively positive charge and a quantitative decrease takes place in electrostatic attraction generated when fine grains of such as silver and silver oxide having tendency to display its relatively positive charge in the similar way in the bulb 1 come into contact with the film surface portion. It is thereby possible to prevent blackening caused due to adsorption of mercury or mercury oxide on the surface of the fluorescent film 2.

Title: Microwave laser
Inventor: TAKAHASHI HIDEOMI
IPC: H01S3/0975
Filed: 1990-02-13
Abstract: PURPOSE:To obtain uniform glow discharge under a normal gas pressure by a method wherein a discharge part for DC or low frequency use is provided on the inner side surface of a discharge part. CONSTITUTION:When a voltage of a discharge maintaining voltage or thereabouts is applied to a pair of additional electrodes 11 arranged under a discharge part 7 of a metallic vacuum container 1 from a DC or a low-frequency additional power supply 12 provided outside of the container 1, discharge occurs between the electrodes 11 and electrons existing in the discharge space drift to the wall surface of the container 1 and disappear. As a result, as charges existing in the discharge space can be prevented from being trapped excessively in the discharge space, the electron density in a microwave laser becomes identical with that in an ordinary DC or AC laser and the laser excitation efficiency is improved. Moreover, uniform glow discharge can be obtained under a normal gas pressure by causing glow discharge with a microwave directly in the container 1 which is a waveguide.

Title: High explosive connonball
Inventor: AHIMU ZUITSUPERU
IPC: F42B10/44
Filed: 1989-02-10
Abstract: PURPOSE: To increase and make more uniform the number of fragments by arranging the gas pressure receiving side face on the rear side of a drive band ring in the proximity of the circumferential ridge part and setting the thickness of wall at the tail part substantially equal to that at forward part. CONSTITUTION: The tail part 32 and the tail end face part 38 of a projectile have a wall thickness substantially equal to that (t) at the central part and the forward part of the projectile body. Since the part 32 is tubular up to a transition to the end face 38, pressure resistance of the body increases. Since the gas pressure receiving side face of a rotary band ring 40 is arranged in the proximity of transition from the part 32 to the end face 38, sensitivity of the end face 38 to gas pressure stress is reduced significantly at the time of launching and thereby the wall thickness at the part 32 can be reduced significantly as compared with the forward part of the projectile. At the time of explosion, a large number of small fragments are generated at high speed in the part 32 thus ensuring uniform characteristics of fragment between the body of projectile and the part 32.

IPC: H01L21/203
Filed: 1985-02-18
Abstract: PURPOSE:To prevent leakage of vapor from a molecular beam generating cell by providing a first shutter close to an opening of the molecular beam generating cell and second shutter separated therefrom. CONSTITUTION:A first shutter 6a close to an opening 13 of a molecular beam generating cell 4 and a second shutter separated therefrom are provided to a shutter device. When the molecular beam is desired to be confined in the molecular beam generating cell 4 and not to be introduced into a vacuum vessel 8 in the operation of the shutter device, the shutter 6a is held closed. Since a clearance between the shutter 6a and the opening 13 is very small in this case, the amt. of vapor leaked from the molecular beam generating cell 4 into the vacuum vessel 8 is very small. On the other hand, when the molecular beam is intended to emit, a shutter 6b is held previoously in closed state and a shutter 6a is opened. In this case, the clearance between the shutter 6b and the opening 13 is relatively large, accordingly, appropriate amt. of vapor is leaked through the clearance. Therefore, there is no fear for causing excessive rise of vapor pressure in the molecular beam generating cell.
