IPC: H01Q23/00
Filed: 2001-07-13
Abstract: PROBLEM TO BE SOLVED: To provide an antenna with simple assembly performance and desired electrical characteristics constituted, so as to be made suitable especially for portable and hand-carry type electronic equipment or the like whose space is limited. SOLUTION: An in-box slot antenna 100 integrally formed inside a printed circuit board is divided by mutually connecting a primary conductive face 114 on the upper face and a ground face 102 on the lower face through a through- hole and is provided with a conductive box 112 functioning as a waveguide. Then, a slot 104 is formed on the ground face 102. In this case, a length L of the slot is made almost equal to half-wavelength λ/2, and it is desired that a relation between width W and wavelength λ be expressed as W<<λ. Then, a small dimension d of the structure of the conductive box 112 is made vertical with respect to the ground face 102, and longer dimensions (a) and g are made in parallel with the ground face 102 so that a return constitution can be acquired for the conductive box structure 112.  The dimension (a) can be made almost equal to a dimension calculated by adding quarter the wavelength λg of the waveguide to the width W. Also, the dimension d is set so as to be considerably smaller than λg/4.

IPC: F25C1/14
Filed: 2001-08-08
Abstract: PROBLEM TO BE SOLVED: To provide a function capable of repairing a crack produced in an ice layer. SOLUTION: The ice layer is sequentially produced by a method wherein ice making water is made to flow down on the inner peripheral surface of a drum 15 cooled by a refrigerant from a spray pipe 35 projected into and turned in an area corresponding to the half circle of a spray tank 30 while a separating edge 40, turned integrally with the spray pipe 35, separates the produced ice layer sequentially while following the same whereby flake ice is produced. Ahead of the separating edge 40, a repairing pipe 50 spraying with a small flow rate is projected. Even when a crack is produced in the ice layer ahead of the separating edge 40 in accordance with the biting of the same edge 40, the crack is re-frozen while retaining a supercooled condition by the water spray from the repairing pipe 50 whereby the crack is brought into repaired condition until the separating edge 40 is arrived.  Accordingly, the flake type ice having a predetermined size can be separated by the separating edge 40 without producing too fine flakes.
