Title: Reciprocating type conveying device
Inventor: KUWAI TOMIHISA
IPC: B65G25/06
Filed: 1986-03-19
Abstract: PURPOSE:To make it possible to convey a plurality of articles to be conveyed, in an arbitrary section with an arbitrary timing in an arbitrary direction, by locking a locking means which may be disengageably engaged with the outgoing or returning travel of a carrier at an arbitrary position, to an endless belt member at a suitable timing. CONSTITUTION:When a chain 4 is driven by a motor 1 in one direction to actuate an electromagnetic brake 17 in an outgoing travel locking means 12 in order to stop the rotation of a rotary shaft 15, the body 10 of a carrier 9 is locked to the outgoing travel section 4a of a chain so that a carrier 9 is moved in the outgoing travel direction as the outgoing travel section 4a travels. When the electromagnetic brake 17 is released, the rotary shaft 15 and a sprocket 16 are freely rotated, and therefore, the carrier 9 is released from the travel motion of the outgoing travel section 4a. Similarly, the operation of an electromagnetic brake 21 in a return travel locking means 13 is controlled to engage and disengage the carrier 9 to and from a returning travel section 4a to move the carrier 9 from an arbitrary position in the returning travel direction, and the carrier 9 is then released at another arbitrary position to be stopped. Accordingly, it is possible to minimize detrimental effects to the stream of the succeeding line due to a failure of a carrier.

Title: Apparatus for measuring particle size distribution
Inventor: OYA SAMON
IPC: G01N15/02
Filed: 1991-03-06
Abstract: PURPOSE:To protect a light detecting surface, to suppress the lowering of accuracy caused by a glass plate and to enhance the measuring accuracy of particle size distribution by arranging the glass plate having a reflection preventing film provided to the surface thereof to the front of a solid-state imaging element. CONSTITUTION:An irradiation optical system irradiates a fine particle group with laser beam 2 and a solid-state imaging element 6 detects the diffracted image due to the fine particle group 4 and an operation circuit 7 operates the particle size distribution of the fine particle group 4 on the basis of the pattern of the detected diffracted image. A glass plate 8 having a reflection film 9 provided to the surface thereof on the side separated from the element 6 is arranged to the front of the element 6. A part of the laser beam 2 applied to the fine particle group 4 is diffracted by the fine particle group 4 to be condensed by a lens 5 and transmits through the glass plate 8 to irradiate the front of the element 6 and this diffracted image is detected by the element 6. In this case, since the greater part of multiple reflection is prevented by providing the reflection preventing film 9 to the glass plate 8, the pattern of the diffracted image can be measured with high accuracy.

Title: Waveguide type optical device
IPC: G02F1/035
Filed: 1992-03-19
Abstract: PURPOSE:To obtain the optical waveguide type device which can make low-loss optical connection as the optical connection having a desired optical coupling characteristic can be executed with good reproducibility by setting the clad diameter of an optical fiber and the length of the optical waveguide exposed on side walls at prescribed values. CONSTITUTION:The coupling of evanescent waves takes place between the optical waveguide 2 exposed on the side walls of a level difference 1a and the optical fiber 4, by which a directional coupler is formed. The transfer and reception of light are, therefore, executed between the optical waveguide 2 and the optical fiber 4. The coupling characteristic of this directional coupler is determined by the thickness of the clad of the optical fiber 4 in contact with the side walls, i.e., the distance between the optical waveguide 2 and the core. Since the thickness of the clad is determined with good controllability, the optical connecting structure has good reproducibility and the device having the same optical coupling characteristic is eventually produced.

Title: Method of removing inflammable matter in air current
Inventor: SHIMIZU MAKOTO
IPC: F23G7/07
Filed: 1978-05-27
Abstract: PURPOSE:To reduce the production of soot and to utilize combustion gas for drying purpose, by catching floating inflammable matter in air current by means of filter located at an exhaust line and by burning off the caught inflammable matter by the use of an exhaust gas heat. CONSTITUTION:An inflammable matter, such as non-burning carbon etc., is included in an exhaust gas, whose temperature is 450 to 550 deg.C, exhausted from marine engine 1 and the like. If a filter unit 2 made of metal fiber is located at an exhaust line 4 of the exhaust gas, soot in the exhaust gas adheres to the filter unit 2 and is oxidized by the heat of the exhaust gas and oxygen in the exhaust gas, and thus, the inflammable matter is burned. Inorganic ash becomes the principal component of the exhaust gas passing through the filter unit 2, and the gas is fed to an economizer 3 recycling the exhaust gas heat. And thus, the heat will be recycled so that the exhaust gas having the reduced soot can be utilized as energy. The matter adhered to a heat recycling device has a weak adhesive power, and can be easily cleaned.
