Title: Original size detecting device and method
Inventor: SUGIYAMA YOSHIHIDE
IPC: G03B27/62
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To provide an original size detecting device and an original size detecting method capable of preventing the presence/absence of an original from being erroneously detected and accurately detecting original size. SOLUTION: A detection sensor 14 detecting the presence/absence of the original 20 detects the pressing surface 19 of an original cover 18 at a closed position C where the cover 18 is closed and does not detect the surface 19 at a half-opened position B where the cover 18 is half opened. The original 20 or the surface 19 of the cover 18 is detected at the positions B and C. Whether or not the original 20 is larger than specified size is decided based on the result of detection performed twice.

Title: Optical shaping device
Inventor: MARUYAMA TERUNORI
IPC: B29C35/08
Filed: 1993-02-04
Abstract: PURPOSE:To easily alter the working content of optical shaping corresponding to the high and low regions of accuracy by irradiating a resin layer with light beam from above through a light pervious plate having release capability on the surface thereof to form a solidified resin layer. CONSTITUTION:A light pervious plate 11 is provided in an upper lid 22 in an easily detachable state and made easily detachable with respect to the liquid surface 52s of a resin soln. 5A. In the case of highly accurate shaping, the upper surface of a liquid tank 9 is hermetically closed in such a state that the upper lid 22 and the light pervious plate 11 are always brought into contact with the resin soln. 5A to perform optical shaping. A coating surface 14 composed of a lubricating material is provided on the single surface of the light pervious plate 11 to apply release capability to the plate 11. Therefore, even when a solidified layer 12 is formed by the irradiation with light beam 40, the solidified layer 12 is easily released from the light pervious plate 11. As a result, the quantity of the movement of a support stand performed at each time when one solidified layer is formed can be reduced.

Title: Manufacture of polypropylene board with saw-dust mixed-in
Inventor: TSUNODA HIROATSU
IPC: B29C48/08
Filed: 1983-02-07
Abstract: PURPOSE:To obtain a compound board made of polypropylene by one process by a monospindle extruder, by adding a mixing medium to a mixture of polypropylene resin and saw dust. CONSTITUTION:Polyethylene of low molecular weight or ataxic polypropylene is added in addition with polypropylene resin and saw dust. Although mean molecular weight of a medium differs with grades and blending rates of the saw dust to be used, it can be limited within a comparative narrow range of 1,000- 4,000. When the mean molecular weight exceeds 4,000 it becomes not only that a bite into an extruder is not favorable and an extruding quantity is deteriorated extremely but also that an extrusion pattern and ruggedness are generated on the surface of a board to be extruded, through which a good board is not obtained. Even if the mean molecular weight is less than 1,000, the bite into the extruder is deteriorated and an effect as a mixing medium can not be displayed to its full capability. As for an additive rate of the medium, 20-40pts.wt. polypropylene resin is appropriate against 100pts.wt. polypropylene.

Title: Fet multistage amplifier
Inventor: KIYONO KIYOHARU
IPC: H03F3/60
Filed: 1987-01-28
Abstract: PURPOSE:To realize miniaturization of the titled amplifier without deteriorating a noise characteristic, by providing a resistance between a gate terminal and a gate bias terminal, as a bias circuit for applying a bias voltage to the gate terminal of an FET placed in the post-stage of the amplifier. CONSTITUTION:A resistance 32 is connected between a connecting point of an input matching circuit 11 and a gate terminal 6 of an FET 5, and a gate bias terminal 26, and constitutes a bias circuit 30. In general, between a gate terminal and a source terminal of the FET, a capacitor is formed, therefore, a part between both said terminals becomes open as DC. Therefore, a bias voltage applied from the terminal 26 is applied to the terminal 6 as it is. Also, by selecting large a value of the resistance 32, the impedance which has viewed the circuit 30 side from said connecting point can be increased, therefore, the circuit 30 has almost the same operation as the bias circuit constituted of a conventional distributed constant line and the capacitor.

IPC: G01J1/02
Filed: 1985-02-01
Abstract: PURPOSE:To increase the input power of a photodetection diode and to improve the S/N ratio of a system by increasing coupling power from a light source to an optical fiber. CONSTITUTION:A laser diode is used for the light source 10 as a substitute for a light emitting diode. Consequently, the coupling power to the optical fiber 12 can be increased. The fiber 12 is led to a sensor body 13, form which an optical fiber 14 is extended and coupled with the photodetection diode through an optical connector 15. The power that the diode 16 receives is therefore increased. Thus, the input power of the diode 16 increases and the S/N ratio of the system is also improved. Further, the driving current of the laser diode 10 is made much higher in signal frequency than the signal frequency that the sensor detects, thereby obtaining a stable measured value.
