A thermosensitive recording material comprising a recording layer formed on a substrate and a coating film layer formed thereon, wherein the recording layer is of a bilayer structure composed of a first thermosensitive layer on the side of the lower layer and a second thermosensitive layer on the side of the upper layer and particles are dispersed in at least one of the first and second thermosensitive layers. An original plate for lithographic printing can be produced from a combination of an ink-philic resin and an ink-repelling resin as the compositional materials of such thermosensitive layers. Besides, thermosensitive, recording materials for magnetic recording, thermosensitive materials for electrostatic recording, thermosensitive recording materials for colored image recording and the like, can be generated through a variety of modifications of the compositional materials. Then, the use of such thermosensitive recording materials attains thermosensitive recording at a higher precision through simple processes and procedures.

摘要:
An image forming apparatus includes an image bearing member, a developer container, a first calculator, and a second calculator. The first calculator calculates an amount of the developer supplied to the image bearing member from the developer container, on the basis of an amount of the developer measured by a measuring device after an image forming operation, and an amount of the developer initially contained in the developer container. A controller outputs an information signal relating to the developer amount accumulated in the collection container on the basis of the amount of the developer calculated by the first calculator and the amount of the developer calculated by the second calculator.
摘要:
The present invention has an object of providing a liquid crystal display device having a high transmittance or a high viewing angle characteristic. A liquid crystal display device according to the present invention includes a pixel electrode (30) including a peripheral portion (36), an island portion (32) and a plurality of branch portions (34). The plurality of branch portions (34) are formed of a plurality of first through fourth branch portions (34A through 34D) respectively extending in first through fourth directions. By these branch portions, first through fourth regions (35A through 35D) in which liquid crystal molecules are aligned in different directions from each other at the time of voltage application are formed. The island portion (32) is surrounded by the first through fourth regions (35A through 35D), and is connected to the peripheral portion (36) by a connection portion (38) but not by any of the plurality of branch portions (34) or connected to the peripheral portion (36) by one of the first through fourth branch portions (34A through 34D).
摘要:
A gaming machine executes a process with new entertainability. The game executes a normal game accepting an input of selecting any of the plurality of the specific symbols stop-displayed, in response to a fact that a plurality of the specific symbols are stop-displayed, in the normal game executed. A benefit is awarded according to the specific symbols selected. Whether or not to generate a specific game state is determined, in response to the specific symbols selected. An input of selecting a specific symbol other than the specific symbol previously selected is accepted from among the plurality of specific symbols stop-displayed, in response to a fact that it is determined that the specific game state has been generated. A benefit is awarded according to the specific symbol selected in the last processing.
