Abstract: A solid-state imaging device includes: a photoelectric converting section comprising a photo-diode; a charge storage section; a charge transfer section; a first control gate section provided between the photoelectric converting section and the charge storage section to control transfer of a signal charge from the photoelectric converting section to the charge storage section; and a second control gate section provided between the charge storage section and the charge transfer section to control transfer of the signal charge from the charge storage section to the charge transfer section. The charge storage section includes: a first region formed on a side near to the first control gate section; and a second region formed on a side near to the second control gate section and configured to have a channel potential increased more than that of the first region. The second region is configured to hold the signal charge in a pinning condition.

Abstract: An apparatus for everting and inserting a pipe-lining material to rehabilitate an underground pipeline comprises an everting nozzle that is disposed so that an opening thereof faces an opening of the pipeline. The pipe-lining material is brought un-everted up to the everting nozzle and attached to the nozzle opening thereof and fluid pressure is applied inside the pipe-lining material to evert and insert it in the pipe-extending direction of the pipeline to be rehabilitated. Eversion of the pipe-lining material is started at the location of the pipeline opening and the pipe-lining material remains flat without being everted in a curved portion where the travel direction of the pipe-lining material changes toward the pipeline opening. This allows no considerable friction to be generated at the curved portion and the pipe-lining material to be smoothly and reliably everted and inserted into the affected pipeline.

Abstract: An apparatus for everting a pipe-lining material for rehabilitating an existing pipe. The apparatus has a storage container for storing a pipe-lining material in an un-everted state, an eversion nozzle for everting the pipe-lining material, and a mounting pipe for removable connection between the storage container and the eversion nozzle. The everting nozzle has a nozzle opening to which the un-everted pipe-lining material is attached and which confronts an opening of the pipeline to be rehabilitated during use of the apparatus. The mounting pipe has an exterior surface, an interior space, a side portion provided with at least one opening communicating the exterior surface with the interior space, and an upper portion with an open end through which the un-everted pipe-lining material is inserted for attachment to the nozzle opening of the eversion nozzle.

Abstract: An apparatus is provided for everting a tubular pipe lining material for rehabilitating an existing pipe. The apparatus has a sealed storage container storing a rotary body around which the pipe lining material is wound in a roll. An electric motor undergoes rotation in a first rotational direction to rotate the rotary body to wind the pipe lining material on the rotary body and undergoes rotation in a second rotational direction opposite to the first rotational direction. An eversion nozzle is attached to the storage container for everting the pipe lining material. When fluid pressure is supplied into the storage container to pull the pipe lining material out from the storage container and evert it via the eversion nozzle, the electric motor is caused to rotate in the second rotational direction due to the pulling out of the pipe lining material and to function as an electric generator to brake the pullout of the pipe lining material.

Abstract: A pipe lining material is wound in a roll on a rotary body using an electric motor, and stored in a storage container. Wen everting, compressed air is applied within the storage container to pull the lining material from the storage container and evert it via an eversion nozzle attached to the storage container. At this time, the electric motor functions as an electric generator and brakes the pullout of the pipe lining material. With such a constitution, the pullout speed of the pipe lining material is substantially constant and the pipe lining material can be smoothly everted with little pullout resistance.

Abstract: A charge transfer device according to the present invention comprises 4n (where n is a positive integer) initial-stage charge transfer registers to which a plurality of photoelectric converters is connected and a charge detection unit detecting a charge transferred from the initial-stage charge transfer registers in sequence via a secondary-stage charge transfer register. The merging of two charge transfer registers adjacent to each other among the initial-stage charge transfer registers into one charge transfer register disposed in the secondary stage is repeated at least once, and the final two charge transfer registers after merging are connected to one charge detection unit.
