Title: Antenna circuit and wrist mount type radio equipment
Inventor: HAMA NORIO
IPC: H04B1/38
Filed: 1989-07-06
Abstract: PURPOSE:To attain transmission/reception with always a constant sensitivity independently of the size of an arm of a person in use by cutting off part of a loop antenna so as to be mounted onto the arm and varying automatically the electric coupling capacitor of a connector in response to a change in the length of the loop antenna. CONSTITUTION:In the case of a person having a thin arm, the circumferential length around the arm for wrist bands 101, 102 is decreased, but an area overlapped between a metallic plate 105 and a loop antenna 104 is increased and the electric coupling capacitance caused by the overlapped area is increased. In the case of a person having a thick arm conversely, the circumferential length around the arm for wrist bands 101, 102 is increased, but an area overlapped between the metallic plate 105 and the loop antenna 104 is decreased and the electric coupling capacitance caused by the overlapped area is decreased. Since the bands have a connector structure whose electric coupling capacitance is automatically changed in response to a change in the length of the loop antenna, even when the size of the arm of the person to which the antenna is mounted is changed, stable transmission/reception is attained with a constant sensitivity automatically without special adjustment even when the size of the arm of wearing person changes.

IPC: C21C7/10
Filed: 1993-07-15
Abstract: PURPOSE:To improve the desulfurizing efficiency by injecting or adding flux for refining on molten steel surface while heating the molten steel in a vacuum treating apparatus with a burner. CONSTITUTION:The molten steel 3 in a ladle 1 is sucked and circulated into the vacuum treating device 2 arranged on the ladle 1 to execute the degassing treatment.
