Title: Photo line sensor
Inventor: MIYAMOTO YOSHIHIRO
IPC: H04N5/335
Filed: 1980-03-19
Abstract: PURPOSE:To prevent the value of a voltage from changing even in the position distant from the voltage supply terminal, by applying a DC voltage to the transfer gate and by applying the control voltage for charge transfer to the conductive light shield film covering the upper face of the photodiode. CONSTITUTION:When pulse control voltage Vc is applied from terminal 36 to light shield film 14b covering photodiode 1, the charge surface is lowered. If light hv is incident through gap (d) between light shield films 14a and 14b, signal charge generated by photoelectric conversion is stored, and as a result, the charge surface is raised. When voltage Vc becomes zero, signal charge is transferred to the well of reading means 7 because the charge surface generated by signal charge is raised. Thus, since the voltage applied from one end of transfer gate 2 is a DC voltage, an equal potential exists in any position of gate 2. Since films 14a and 14b are made of low-resistance conductive materials, distortion and delay are not generated in the control voltage waveform at points distant from the sending terminal even if voltage Vc is applied.

Title: Power transmission gear
Inventor: NAKAMICHI MASAKAZU
IPC: F16H57/02
Filed: 1985-02-25
Abstract: PURPOSE:To prevent the vibration generated in a larger reduction gear from being transmitted to a transmission case as well as said vibration being damped by friction, by utilizing a frictional force generated through pushing action of a conical spring material for shifting the larger gear in a reduction gear train in the direction of a thrust. CONSTITUTION:A driven shaft 17, an intermediate shaft 18 and a rear axle 20 are supported on the transmission case 12. The larger gear 35 in a reduction gear train is fixed on the intermediate shaft 18 and is in mesh with a smaller reduction gear 34 of the driven shaft 17. A conical spring member 38 is interposed between the end face of the larger reduction gear 35 and the wall face 16a of the transmission case 12 with the periphery of the spring member 38 pressed into contact with the rim 41 of the larger reduction gear 35. The larger reduction gear 35 is pushed in the direction of thrust by main of said spring member 38, thus a frictional force being generated on the pushed surface. Since the periphery of the spring member 38 is pressed in contact with the rim 41 of a large diameter, the pushing force in the thrust direction is enlarged to give a frictional force of a considerable magnitude on said periphery.

Title: File controller
Inventor: KOJO FUMIYASU
IPC: G06F17/30
Filed: 1988-02-18
Abstract: PURPOSE:To effectively process plural picture information output requests which are produced simultaneously or continuously by a host computer by reading picture information requested by the host computer out of a picture information memory and writing it into a buffer memory during the output of the picture information stored in the buffer memory. CONSTITUTION:When an output request is received from a host computer 9 for the picture information stored in an optical deck 5 or 6 during the output of the picture information stored in a buffer memory 25, a computer interface 8 actuates the corresponding optical deck adaptor 14 or 15. In this case, a file controller 13 stores the picture information read out of the deck 5 or 6 into an idle buffer memory 24. Thus it is possible to effectively process the request when the plural picture information output requests generated simultaneously or continuously from the computer 9.

IPC: C08L7/00
Filed: 1986-02-20
Abstract: PURPOSE:To prevent segregation of the obtained polyolefin masterbatch pellet mixture effectively, by adding an anti-static agent to the pellets at a specified weight ratio in diluting polyolefin masterbatch pellets containing an additive at a high concentration with polyolefin pellets. CONSTITUTION:Polyolefin masterbatch pellets are produced by adding at least one additive (e.g., an inorganic filler or an organic pigment) to a polyolefin (e.g., high-pressure process polyethylene or polypropylene) to produce masterbatch pellets of a high additive concentration. These masterbatch pellets are mixed with pellets of a polyolefin containing no additive to adjust the concentration of the additive in the mixture to a concentration suitable for molding. At this time, 0.005-2 PHR of an antistatic agent (e.g., stearic mono glyceride or polyoxyethylenealkylamide) is added with agitation to the pellet mixture to prevent regregation of the mixture.

Title: Optical amplifier
Inventor: MASUDA KOJI
IPC: G02F1/35
Filed: 1992-02-24
Abstract: PURPOSE:To remove the excessive loss of a signal light branching unit and the coupling loss of the signal light branching unit and a multiplexer which multiplexes the signal light and exciting light by providing a branching function for signal light by deviating the branching ratio of the multiplexer to the signal light from an optimum multiplexing value. CONSTITUTION:The signal light and exciting light are guided in an optical amplifying medium 3 through a multiplexer and branching unit 9. Part of the signal is branched from the multiplexer and branching unit 9 and monitored by a photodetector 6, whose output is guided to a control circuit 8. This multiplexer and branching unit 9 deteriorates in neither the multiplexing function nor insertion loss, so the coupling loss of the signal light branching unit and multiplexer of conventional technology can be removed. Then the branching ratio of the multiplexer and branching unit 9, which multiplexes the signal light and exciting light, to the signal light is deviated from the optimum multiplexing value to provide the multiplexer and branching unit 9 with the signal branching function, thereby reducing the loss of insertion into a transmission line as compared with a case wherein the multiplexer which multiplexes the exciting light and signal light and the branching unit which branches the signal light are composed of individual elements.

Abstract: PURPOSE:To detect a line disconnection separately from any other communication error by providing a means for judging a line disconnection when a clock number is less than a set lower limit clock number, a line disconnection informing means, and the like. CONSTITUTION:With the output of an interruption signal from an interruption timer, whether a count value of a counter is not less than 70% of a communication Baud rate (minimum number of clock pulses) is judged (ST1). If it is judged to be not less than the minimum number, whether a previous line disconnection state is turned to a line recovery state is judged by judging whether data representing a line disconnection is set on a line state flag. On the other hand, if it is judged to be less than the minimum number (by a disconnection judging means), whether a previous line recovery state is turned to a line disconnection state is judged by judging whether data representing a line recovery state is set on the line state flag. If a line recovery state is judged, a counter value is set to zero, and a timer interruption processing is terminated.
