Title: Lid member with hot water draining function
Inventor: GOTO MASASHI
IPC: B65D53/04
Filed: 2004-12-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide a lid member with a hot water draining function which is made of paper as a base material, has no problem on hot water draining properties, and exhibits less remaining of hot water when the hot water is drained.  <P>SOLUTION: A container for food is made by sealing a lid member having an approximately the same outer shape as that of an opening part of a container body and having a knob for unsealing and a knob for opening a hot water draining opening, on the opening part of the container body. The lid material 10 is made by laminating an inner face base material 11 and a surface base material 12 through an adhesive 13. The inside of the surface base material is partitioned into a releasing region A coated with a releasing agent 14 and a non-releasing region B adjoining the releasing region. On an overlapping part of the inner face base material to the releasing region of the adhesive layer, a half cut line (a) for forming the hot water draining opening is formed in a range from the inner face base material to the adhesive layer. In addition, the knob for the hot water draining opening is provided on the releasing region side in the vicinity of the boundary line between the non-releasing region and the releasing region arranged so as to adjoin the releasing region. A half cut line b for releasing reaching the adhesive layer from the surface base material along a boundary line of the non-releasing region adjoining the releasing region, is formed.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

IPC: H05B41/24
Filed: 2004-12-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide a lighting device with a long life of its electrode, capable of restraining generation of flicker.  <P>SOLUTION: A down converter 12 and a full-bridge circuit 13 generate an alternating current wave form turning a current value at the start of a half-cycle into a value of a steady current. A control part 11 generates a current waveform including a period in which a value of a current supplied to the lamp 30 decreases from the value of the steady current to a first current value, a period in which the value of the current supplied to the lamp increases from the value of the steady current to a second current value larger than the first current value in a form of a quadratic curve, and a period maintaining the value of the second current until the end, as a current wave-form at half cycle. The decreased amount of the energy of the current wave-form at the half-cycle against a standard energy at the first period in which the value of the current supplied to the lamp is lower than the value of the steady current is made equivalent with the increased amount of the energy against the standard energy at the second period in which the value of the current supplied to the lamp is higher than the value of the steady current.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
