Title: Grid for x rays
Inventor: TAKEUCHI MASAHARU
IPC: G21K1/02
Filed: 1998-12-17
Abstract: PROBLEM TO BE SOLVED: To make it possible to improve contrast and resolution by placing a cladding layer on a sheet grid made by alternately laminating a band-shaped film to which a paint blended with heavy metal is applied and a band-shaped spacer of wood or paper. SOLUTION: A thin film 14 of about 10 μm is formed by preparing and applying 13 an emulsion paint of a vinyl acetate family where a few kinds of heavy metal compounds are mixed in an appropriate compounding ratio to a plate 12 of wood or paper to make a plate 15. It is cut by a pushing blade 9 in the thickness in which a grid is effective, with the thin film 14 located on the bottom, and a plate made by converging and laminating strip pieces 15' of the cut plate 15 is covered with carbon fiber. This makes it possible to obtain a grid for X rays where stripes caused by the thin film 14 are not a problem in diagnosis and that is suitable for mammography. In this case, the plate 15 is cut with the thin film 14 located on the bottom, which prevents the grid from being brought in and makes it possible to eliminate the necessity of a finishing cutting process.

Abstract: PROBLEM TO BE SOLVED: To achieve structure in which a light emitting tube is difficult to be broken even if force is transmitted from an electrode base to the light emitting tube. SOLUTION: An annular fluorescent lamp comprises a small annular portion 10 having a small annular diameter and a large annular portion 20 having a large annular diameter, which are obtained by forming tubes having the same tubular diameter into an annular shape. An electrode 31 on a small annular portion side is attached at one end of the small annular portion 10. An electrode 32 on a large annular portion side is attached at one end of the large annular portion 20. The small annular portion 10 and the large annular portion 20 are arranged flush and concentrically with each other.

The other end (non-electrode side) of the small annular portion 10 and the other end (non-electrode side) of the large annular portion 20 are connected to each other bypassing near the electrodes 31, 32, thereby forming a bisected connection tube 40 where an intermediate portion 42 extends in the radial direction of the annular portion. A series of discharge paths for discharging via the small annular portion 10, the bisected connection tube 40 and the large annular portion 20 are formed between the electrodes 31, 32. An electrode base 50 having a wiring connection portion 52 for the electrodes 31, 32 is provided for covering the bisected connection tube 40, the electrodes 31, 32.

Title: Game ball hitting device
Inventor: FUKUSHIMA SHOGO
IPC: A63F7/02
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To cope with the enlargement of a motor control substrate with respect to the game ball hitting device. SOLUTION: Relating to this game ball hitting device 10, since a swinging ball hitting rod 14 and a rotating drive cam are disposed on the front surface side of a base plate 12, the swinging area of the ball hitting rod 14 and the rotating area of the drive cam (area actually incapable of arranging other components) are turned to the front surface side of the base plate 12. Since it is not required to provide the area for such swinging and rotating members on the side of the back surface 12b of the base plate 12, the component installation area of the base plate 12 is fully used, a motor 18 is attached and the motor control substrates 5a and 5b are parallelly attached to the base plate 12.  Even when the motor control substrates 5a and 5b are enlarged and an occupancy area on the base plate 12 becomes large, the need of enlarging the base plate 12 is eliminated and thus, the enlargement of the game ball hitting device 10 is prevented.
