The discharge lamp operating circuit comprises two series circuits, each including two switching devices, connected in parallel with the power supply, a series circuit, including a choke coil, a first capacitor, and a parallel circuit with a discharge lamp and a second capacitor, and connected between the middle points of the one and the other series circuit, reverse-direction rectifiers connected in parallel with the corresponding switching devices, said discharge lamp operating circuit turning on and off said discharge lamp by turning on and off the switching devices alternately. In this discharge lamp operating circuit, the timing of switching the switching devices is set from the closed condition to the open condition at a time when the current flowing through the switching devices is almost at zero level.

A discharge lamp operating circuit includes at least a discharge lamp, a condenser and four switches. The condenser is charged and discharged through the discharge lamp by the turn-on and turn-off of the switches so that an AC current is caused to flow through the discharge lamp to operate the discharge lamp. A time required for the complete charging and discharging of the condenser is selected to be longer than a time scheduled for the charging and discharging of the condenser in one period. A switching frequency f.sub.0 at the time of heating of the discharge lamp and a switching frequency f at the time of operating of the discharge lamp has a relation of 2.ltoreq.f/f.sub.0 .ltoreq.10.

Disclosed are: a gene transduction method for use in the induction of the differentiation of stem cells such as ES cells or iPS cells into hepatocytes effectively; stem cells into each of which a gene useful for the induction of the differentiation into hepatocytes is introduced; and hepatocytes produced from stem cells each having the gene introduced therein. A specific gene can be introduced into stem cells such as ES cells or iPS cells using an adenovirus vector. The effective induction of the differentiation into hepatocytes can be achieved by introducing the gene. Specifically, the effective induction of the differentiation of stem cells such as ES cells or iPS cells into hepatocytes can be achieved by introducing at least one gene selected from HEX gene, HNF4A gene, HNF6 gene and SOX17 gene into the stem cells.

A packing band having a superior weld is disclosed. The band can be made of a stretched thermoplastic resin having a flat cross section. The weld is formed by overlapping ends of the band extending in the lengthwise direction thereof. The weld portion of the band includes a plurality of welded sections separated by at least one non-welded section along the lengthwise direction of the band. The welding of the packing band can be accomplished by overlapping parts of the band in a lengthwise direction thereof; melting discontinuous portions of the parts in a pattern along the length of the band parts of a melted portion, an unmelted portion and a melted portion; and then pressing the parts together so that the melted and unmelted portions of the parts contact each other and form a weld.

In accordance with an embodiment, a simulation apparatus includes a two-dimensional section dividing processing unit, a two-dimensional simulator, a one-dimensional combining processing unit, and a three-dimensional shape combining processing unit. The two-dimensional section dividing processing unit divides a three-dimensional shape as a simulation target into at least one set of two-dimensional sections intersecting with each other and defines the three-dimensional shape as the two-dimensional sections. The two-dimensional simulator runs a two-dimensional shape simulation in each time step for each of the two-dimensional sections obtained by the dividing and acquires a two-dimensional shape. The one-dimensional combining processing unit extracts a film configuration for each intersection of the two-dimensional sections from the acquired two-dimensional shape and combines the film configurations to acquire one-dimensional film configurations. The three-dimensional shape combining processing unit creates a three-dimensional structure from the acquired one-dimensional film configurations on the basis of information on the intersection.
