20160047932 | ELECTRIC NEAR-FIELD PROBE, CONTROL SYSTEM FOR SAME, AND PIEZOELECTRIC CRYSTAL DETECTOR - Provided is a compact and lightweight electric field probe which has a transmitting/receiving function whereby piezoelectric crystals can be excited through the application of an alternating current electric field thereto, and piezoelectric effect signals can be detected with sufficient sensitivity. Also provided are a control system for the same, and a piezoelectric crystal detector. The electric near-field probe is provided with a capacitor, in which the space between two metal plates that are positioned parallel to each other is filled by a conductor or air, and a series resonance circuit, which has a prescribed resonance frequency and is connected in series to an inverter that is formed by winding a conductive wire around a toroidal core. The electric near-field probe is configured such that: an electric near-field, which originates from the leakage electric field from the capacitor generated by the application of alternating current voltage to the series resonance circuit, is transmitted to the piezoelectric crystals, and the piezoelectric crystals are excited; and the piezoelectric effect signal, which is generated by the excited piezoelectric crystals, is received by the capacitor, and is detected by the series resonance circuit. The control system is for said electric near-field probe. | 02-18-2016 |

20090039117 | Eyeless Sewing Needle and Fabrication Method for the Same - In an eyeless sewing needle, a periphery of an axial hole at the base end is heated to make a fibrous structure be a granular structure without directionality, and at least a part of a heat-affected zone made between the fibrous structure and the granular structure due to the heating is within a range that is three times the diameter of the sewing needle and that extends from an effective base of the axial hole towards the needlepoint. This allows provision of a flexible sewing needle so that the hole periphery can be processed while keeping a hard state at the position of the needlepoint slightly away from the axial hole. | 02-12-2009 |
