Title: Steam turbine
Inventor: KANO YOSHIO
IPC: F01K7/38
Filed: 1989-03-16
Abstract: PURPOSE:To make it possible to get rid of pressure difference arising in a bleeding chamber at the time of bleeding by making a bleeding port provided along circumference on the outer peripheral face of a turbine blade chamber smallest at the part nearest to a bleeding pipe and gradually larger as going farther. CONSTITUTION:A bleeding chamber 30 is provided as surrounding a turbine blade chamber 15, and a bleeding pipe 31 for making bleeded steam flow out is connected to the bleeding chamber 30. A bleeding port 35 is provided along circumference on outer peripheral face of the turbine blade chamber 15 so as to communicate the bleeding chamber 30 to the turbine blade chamber 15. Hereupon, the bleeding port 35 is made to be smallest at the position nearest to the bleeding pipe 31 and gradually larger as going farther along the circumference. Thereby, steam flows into the bleeding chamber 30 from a large opening at the position far from the bleeding pipe 31, and flows in from a small opening at near position, therefore steam entering into the bleeding chamber 30 cancels pressure loss at the time of flowing toward the bleeding pipe 31 in the bleeding chamber 30 with each other and balances, so pressure unbalance never arises in circular direction of main flow in the turbine blade chamber 15.

Inventor: MURAKAMI HARUNORI
IPC: H01Q5/10
Filed: 1993-03-23
Abstract: PURPOSE:To provide the frequency switching type glass antenna which can be arranged in nearly the same space with a monopole antenna. CONSTITUTION:A 1st pattern 2 for radiation is arranged on a glass surface vertically, a 2nd pattern 3 for radiation is arranged above it, and a grounding pattern 4 is arranged below it to form the glass antenna 1.

Filed: 1986-03-25
Abstract: PURPOSE:To reduce the cost and to speedup a photolyso process by providing a photomask with a pattern generating function and controlling the photomask to produce an optional mask pattern. CONSTITUTION:A liquid crystal plate 21 is arranged on the photomask 2 and plural X and Y axis electrodes are arrayed oppositely on both the sides of the liquid crystal plate 21 like matrixes. The X and Y axis electrodes are connected to a pattern controller and voltage is selectively impressed to an optional electrode in the X axis electrodes and an optional electrode in the Y axis electrodes to change the transparency of the liquid crystal plate and produce the pattern 2a of the photomask 2. Parallel beams such as ultraviolet rays are projected to the photomask 2 and the light transmitted through the pattern 2a is contracted by a lens 3 and exposed to a photoresist 5. Since the mask pattern can be changed without replacing the photomask, the cost can be reduced and the work can be speeded up.
