Title: Polarization conversion element, projector and method for manufacturing the polarization conversion element
Inventor: KIMURA YUICHIRO
IPC: G02B5/30
Filed: 2008-03-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a polarization conversion element whose productivity can be improved, without deteriorating a retardation characteristic, and to provide a method for manufacturing the polarization conversion element, and a projector.  <P>SOLUTION: Since the polarization conversion element 8 includes a retardation plate 82, constituted of a single quartz crystal wafer on which first retardation portions 821 for converting linearly polarized light of transmitted light by 360° or 180° and second retardation plates 822 are arrayed alternately, it is unnecessary to have the retardation plate 82 configured by sticking a plurality of quartz crystal wafers to each other. Thereby, as compared with a case in which the retardation plate 82 is configured, by sticking the plurality of quartz crystal wafers to each other, manufacturing errors can be reduced and the plate thickness accuracy of the retardation plate 82 can be improved. Furthermore, since the processing of a plurality of quartz crystal wafers becomes unnecessary, and a step for sticking these quartz crystal wafers to each other is unnecessary, so that increase in the manufacturing cost can be prevented, and the risk that cycle time becomes extended due to addition of manufacturing steps is eliminated.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Title: Crushed sand washing device
Inventor: ITSUMI MITSURU
IPC: C04B14/02
Filed: 2008-03-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a crushed sand washing device capable of efficiently removing graphite stuck to crushed sand in a simple structure.  <P>SOLUTION: A supply port 9a of a separation tank 9 is provided with a crushed sand inflow gutter 14 for receiving mixed water for which the crushed sand and washing water are mixed, and a collision plate 15 which interrupts the flow path of the mixed water flowing down from the exit of the crushed sand inflow gutter 14 and is curved in a concave shape to the upstream side of the flow path of the mixed water. When the mixed water which flows in from the crushed sand inflow gutter 14 collides with the collision plate 15, it splashes back in the direction of narrowing the flow path, and the crushed sand in the mixed water is closely packed and scratches each other when rebounding from the collision plate 15. Thus, almost all of the graphite stuck to the crushed sand is peeled off from the crushed sand and removed.  <P>COPYRIGHT: (C)2010,JPO&INPIT

IPC: H04N21/41
Filed: 2008-04-17
Abstract: <P>PROBLEM TO BE SOLVED: To satisfactorily perform a process of imparting a sound field characteristic to an audio signal in an AV amplifier.  <P>SOLUTION: This audio processing device imparts the sound field characteristic based on genre information received by DSP. However, when the source logical address of the genre information does not match the source logical address of an Active Source message, the imparting of the sound field characteristic based on the genre information is not performed (ST12). It is possible to prevent a false sound field from being set, based on genre information from an apparatus other than an active source apparatus. Even when the logical addresses match, then if a current audio input does not match an audio input assigned to the source physical address of the Active Source message, the imparting of the sound field characteristic based on the genre information is not performed (ST13). When the current audio input is of an apparatus which does not support CEC, it is possible to avoid a problem that a false sound field characteristic is imparted based on genre information from another apparatus.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To precisely control pest insects dropped from a plant by liquid jetting.  <P>SOLUTION: The liquid-jetting type pest insect-controlling device in plant water culture is constituted as follows. Driven belt wheels are axially supported by the front and rear parts of a cultivation vessel storing a culture liquid respectively. A driven belt is stretched from the rear driven belt wheel to the front driven belt wheel so as to be driven to form an upper traveling passage of the driven belt. The driven belt is reversed from the front driven belt wheel to travel the lower part of the cultivation vessel to form a lower traveling passage, and endlessly returned to the rear driven belt wheel. Many plant-planting panels are connected to the endless driven belt so as to travel by being accompanied with the travel of the endless belt. The plant-planting panels take positions in which the plant-planting panel enables the roots to be soaked in the culture liquid in a normal posture directing the leaf and stem part upward when being present on the upper traveling passage, and when being present on the lower traveling passage, the plant takes an inverted posture directing the leaf and stem part downward. A liquid-jetting nozzle for jetting a liquid to the leaf and stem part of the plant-planting panel traveling in the inverted posture is arranged at the lower traveling passage, and a pest insect collecting vessel including a liquid is installed in the lower position of the leaf and stem part.  <P>COPYRIGHT: (C)2010,JPO&INPIT
