The present invention provides an easy-to-produce PTP which exhibits good hermetic sealing performance and which can be readily and reliably opened (without variation) even if the working accuracy is reduced, and also provides its production method. The PTP includes a lid member 3 having a resin film 3a, an aluminum foil 3b, and a thermal adhesive layer 3c, and a container 5 having a flange portion 5b and a large number of pocket portions 5a. The resin film 3a is provided with a plurality of cut pattern units constituting weakening point-cuts 3h arranged in a string 3j. The pitch P1 of the weakening point-cuts 3h along the string is smaller than the pitch of the pocket portions, and at least one of the weakening point-cuts or at least a part of the weakening point-cut falls within a position corresponding to each of the pocket portions.

A multicolor image forming apparatus includes: a photosensitive belt unit comprising; a driving roller; a driven roller; a photosensitive belt having a joint, and a charger charging a surface of the photosensitive belt; an exposure device forming an electrostatic latent image, based on image information of each color, on the photosensitive belt; a plurality of developing devices storing different color developers, and an intermediate transfer unit performing a first transfer by sequentially superimposing each color developer image formed on the photosensitive belt. The photosensitive belt is suspended around the driving roller and the driven roller and is rotated and driven by the driving roller. Each developing device contacts and retracts from the photosensitive belt so as to develop the electrostatic latent image into a visible image using each color developer. At least one developing device can retract from the photosensitive belt at a region other than an image region.

The object of the present invention is to provide a differentiation inhibiting agent which allows culture of a stem cell or an embryonic stem cell in an undifferentiated state without use of any feeder cell, a method for culturing using the same, a cell culture liquid using the same, and a cell prepared by culturing using this differentiation inhibiting agent. The present invention provides a differentiation inhibiting agent which comprises a low molecular weight compound, especially a tetrahydroisoquinoline derivative, as an active ingredient; a method for safely culturing a stem cell in large scale in undifferentiated state in the absence of feeder cell which comprises culturing a stem cell by using a tetrahydroisoquinoline derivative; a culture liquid for stem cells comprising a tetrahydroisoquinoline derivative; and a cell which is obtained by culture using a tetrahydroisoquinoline derivative as a differentiation inhibiting agent.
摘要:
Face detection is executed only on an image imaged based on an arbitrary (predetermined) focal point information defined in advance. In face detection, the face of a person is detected based on a relative value of statistics in a plurality of characteristic regions produced by contour or parts of the face of the person. Thus, even if the face in the image used for face detection is blurred, the statistics in a certain region can be acquired, and thus such face is detectable. Therefore, the primary subject to be focused can be rapidly detected without performing focal point control at a stage of preliminary imaging in the imaging apparatus.

A metal holder has a V-shape in cross-section formed by two arm sections. PET sheets are attached to mutually opposed surfaces of respective arm sections, and part of each PET sheet extends toward the electrically-conductive roller beyond the arm section. Flocked sheets are attached to the surfaces of the respective PET sheets opposite the electrically-conductive roller, and contact the electrically-conductive roller.

A substrate 1 for growing nitride semiconductor has a first and second face and has a thermal expansion coefficient that is larger than that of the nitride semiconductor. At least n-type nitride semiconductor layers 3 to 5, an active layer 6 and p-type nitride semiconductor layers 7 to 8 are laminated to form a stack of nitride semiconductor on the first face of the substrate 1. A first bonding layer including more than one metal layer is formed on the p-type nitride semiconductor layer 8. A supporting substrate having a first and second face has a thermal expansion coefficient that is larger than that of the nitride semiconductor and is equal or smaller than that of the substrate 1 for growing nitride semiconductor. A second bonding layer including more than one metal layer is formed on the first face of the supporting substrate. The first bonding layer 9 and the second bonding layer 11 are faced with each other and, then, pressed with heat to bond together. After that, the substrate 1 for growing nitride semiconductor is removed from the stack of nitride semiconductor so that a nitride semiconductor device is provided.
