Title: Photoelectric conversion device and device mounted therewith
Inventor: OZU ITSUO
IPC: H04N5/3745
Filed: 1990-11-08
Abstract: PURPOSE:To enhance a photoelectric conversion device in output sensitivity by a method wherein an inversion layer is formed inside a first primary electrode region when a first voltage is applied to an electrode, and the inversion is prevented from being formed when a second voltage is applied. CONSTITUTION:In a state that a voltage (V1) is applied through a control terminal wiring 9 to prevent a P-type inversion layer from being formed, signals of low level are applied to reset pulses phiR1 to set a P channel MOS transistor RT in an ON-state and to fix the base potential of a bipolar transistor Tr to a voltage of VBB. Then, a voltage V2 lower than the voltage V1 is applied to a conductive layer 6 through the intermediary of the control terminal wiring 9 to form the P-type inversion layer, and the generation and the storage of carriers are executed according to the entrance of signal light (storage operation). Then, the voltage V1 is applied through the intermediary of the control terminal wiring 9 to extinguish the P-type inversion layer, and then a readout operation is executed. By this setup, a parasitic capacitance induced by a control electrode region can be lessened and a photoelectric conversion device can be improved in output sensitivity.

Title: Device for classifying article
Inventor: ISHII TORU
IPC: B65G47/14
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To provide a device for classifying articles which can put articles in the same postures and can classify them by classes. SOLUTION: A lots of respective articles C are put in postures with projected parts Ca positioned upward and are successively placed on valley parts of respective transportation bands and respective articles placed between respective transportation bands are gradually and vertically descended while being transported in a sending direction. When the valley parts of respective transportation bands 5 become a little wider than a width size of the article C, the article moved at that position is vertically dropped to be classified by classes.  If the posture of the article is shifted in a state in which the projected part Ca is positioned downward, the projected part Ca of the article projecting lower than the valley parts of respective transportation bands is brought into contact with a posture correcting member 26 to turn its downside up and thereby dropping of the projected part Ca downward first can be surely prevented. Thus respective articles can be put in the same postures and can be classified by classes without damaging commercial value.

IPC: G06F17/30
Filed: 1987-12-01
Abstract: PURPOSE:To search a hierarchical network route at a high speed by storing the attribute information on a weight slot showing the priority degrees of the frames showing paths into these frames. CONSTITUTION:A searching device for hierarchical network route includes a network route searching mechanism 110, a working memory part 111, and a route searching mechanism 112. A slot is added to divide the paths on a network into >=2 hierarchical classes in response to the priority degrees of these paths and to store the division of the classes of paths into the network connecting information expressing frames 140, together with a slot, e.g., a WEIGHT slot 200 which stores the attribute values of paths themselves and shows the priority degrees of said attribute values. When a route to be extended next is selected among plural routes under evolution, the value of evaluation is calculated from the attribute values of paths forming each route and the division of classes. Based on said value of evaluation, the paths of higher priority degrees are evolved with preference for acquisition of a route between two nodes. Thus a route searching system is attained with high efficiency.

Title: Fuel injection system for internal combustion engine
Inventor: ITATSU TOSHIRO
IPC: F02D41/00
Filed: 1987-12-01
Abstract: PURPOSE:To alter an injection rate so easily by increasing positive displacement in a pressure control chamber with a piezoelectric element before injection starting. CONSTITUTION:A control signal P2 of a second piezoelectric element group 40b is given out in advance of pilot injection P, and an electric charge stored in the second piezoelectric element group 40b is discharged by a startup of the control signal P2. In consequence, the second piezoelectric element 40b is contracted, and thus positive displacement in both pressure control chambers 27, 38 grows larger. After a little while since the second piezoelectric element group 40b has been contracted, fuel pressure in these pressure control chambers 27, 38 becomes equal to fuel pressure in an accumulator again. Next, a control signal P1 of a first piezoelectric element group 40a is given out and an electric charge stored in this first piezoelectric element group 40a is discharged by a startup of this control signal P1, whereby the first piezoelectric element group 40a is contracted, and a capacity increment in these pressure control chambers 27, 38 also grows larger. Thus a needle valve 26 is opened and fuel injection is started.

Title: Method for separating determining quadrivalent selenium from hexavalent selenium in solution
Inventor: NAKAGAWA HIROSHI
IPC: G01N21/78
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To obtain a correct measurement value from a stable measurement result in a simple operation even when a content of Se<6+> is minute to a content of S<4+> , by adding hydrochloric acid and nitric acid to a solution in which Se<4+> and Se<6+> are dissolved, heating and reducing the Se<6+> to Se<4+> . SOLUTION: Se<4+> , Se<6+> present in a solution are totally reduced to Se<4+> and a total quantity of Se<4+> in the solution is measured. A quantity of Se<6+> is calculated from a difference of the measured total quantity of Se<4+> and a quantity of Se<4+> measured without a reduction process. In the reduction process, hydrochloric acid is added as a reducing agent to the solution containing the Se<4+> and Se<6+> and heated, whereby the solution is reduced to Se<4+> and Se<6+> . At this time, since the Se<4+> is reduced far to Se<6+> to make determination difficult if a reduction process condition is too intensive, nitric acid having a reduction restriction effect is added thereby restricting a reduction reaction. An addition amount is approximately 35% hydrochloric acid and 61% nitric acid of the sample solution.  Too little hydrochloric acid prevents the reduction from proceeding and too much hydrochloric acid forms Se<0> . Also too little nitric acid forms Se<0> thereby lowering a recovery, while too much nitric acid hinders formation of hydride at an analysis time.

IPC: B63H20/00
Filed: 1987-11-30
Abstract: PURPOSE:To enable a dog to be smoothly and surely returned to a neutral position by providing the second detent mechanism in addition to the first detent mechanism. CONSTITUTION:Assuming a case that a dog 30 meshes with a forward gear 56, when a shift sleeve 68 is controlled moving in the leftward direction in the drawing, immediately before a pawl 64 of the dog 30 meshes with a pawl 66 of the gear 56, the first ball 84 is dislocated from the first stopper groove 92 escaping from a neutral position, but the second ball 86 comes into contact with a wide slope 96 of the second stopper groove 94, tending to return into the stopper groove 94. Consequently, the shift sleeve 68 and the dog 30 receive a detent load in a direction of returning to the neutral position. And in a condition that the dog 30 completely meshes with the gear 56, dislocating the second ball 86 from the second stopper groove 94, no detent load acts in the neutral direction. Thus receiving the detent load only by controlling the dog 30 to be released from the meshed condition, the dog is surely returned to the neutral position.

Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To minimize the increase of the cost and to prevent the rising of the temp. of the beating part of a heating roller, at the time of consecutively printing small-width paper sheets by providing an endothermic structure which can come into contact with only both end parts of a pressure roller for exerting pressure on the heating roller and a contact control mechanism for the endothermic structure. SOLUTION: An endothermic plate 103 is supported so that it is switched to contact and noncontact states with the pressure roller 102 by an electromagnetic solenoid 104. When the endothermic plate 103 comes into contact with both end parts of the pressure roller 102, heat is absorbed and the temp. drops in both end parts of the pressure roller 102. Since this roller 102 has elastic structure, the thickness of an inserted paper sheet is absorbed by deflection and both end parts through which the paper is not inserted of the pressure roller 102 come into contact with both end parts of the heating roller 101. The rising of the temp. in both end parts of the heating roller 101 can be suppressed by the contact of both end parts of the pressure roller 102 whose temp. drops.
