Title: Superconductive logical gate
Inventor: TAKARAGAWA KOJI
IPC: H03K19/195
Filed: 1984-08-30
Abstract: PURPOSE:To reduce the initial delay of a current injection type superconductive logical gate, by providing a nonlinear resistance element having a prescribed characteristic in the place of a bias resistance. CONSTITUTION:A nonlinear resistance element JN is connected between an input signal detecting junction J1 and output signal exciting junction J2. The element JN represents a high resistance value when the voltage applied across both ends of the element JN is weak and a low resistance value under voltages higher than a fixed level. When an input signal is impressed upon an input terminal 1 and made to flow to the junction J1, the junction J1 represents nonlinear inductance. As a result, a minute voltage is generate across both ends of the nonlinear resistance element JN. However, the electric current flowing toward the junction J2 becomes extremely small, because of the nonlinear resisting property of the element JN. Accordingly, the junction J1 is switched with an extremely small initial delay. Therefore, the initial delay of this gate can be reduced.

Title: Collating device
Inventor: ITOU MASAHIRO
IPC: B65H39/11
Filed: 1982-10-13
Abstract: PURPOSE:To increase the quantity of storage per bin as well as to improve the productivity of copying work, by installing plural bins in a vertical, multistage manner, while making up the inlet side of each bin expandable by means of arm lever carrying a Y-shaped member and an indexer, in case of a collating device for copying machines. CONSTITUTION:Copying paper entered from B is housed in the first step bin 6 through an indexer 19. This housing is sensed by sensors 28 and 29, causing the indexer 19 to go down. With this, a kick pin 20 of the indexer 19 collides with the lower stage of a Y-shaped part 12B of an arm lever 12 whereby this lever 12 turns round in a counterclockwise direction and, after the pin linking the lever 12 is pushed upward, the kick pin 20 is disconnected from the arm lever 12. In this step, the arm lever 12 holds an upward pushing position by the help of a spring 16 and the inlet of the bin 16 is expanded yet larger. Thus, enlarging each inlet in regular sequence, the quantity of paper storage is increased to the extent of its dimensional limits so that improvements in the productivity of copying work come to fruition.

Title: Advance read control system
Inventor: TEJIMA TORU
IPC: G06F13/12
Filed: 1987-07-17
Abstract: PURPOSE:To prevent the deterioration of the processing seed of an information processing system by excluding completely the invalid advance reading actions with a channel controller and reducing the invalid load against a main memory. CONSTITUTION:The working of an advance reading control means 100 of a channel controller 1 is stopped when it is detected that a transfer request of data is given to an input/output controller 5b from a main memory 3 while this memory 3 is transferring (200) data to another input/output controller 5a. Therefore the means 100 works to carry out an advance reading action when the data are transferred continuously to the same input/output controller from the memory 3. However, the means 100 does not work when the data are transferred to different input/output controllers from the memory 3. As a result, the invalid advance reading actions are avoided and the reactive load of the memory 3 is reduced. Then the deterioration of the processing speed is prevented for an information processing system.

Title: Feed and exhaust cylinder disconnection detecting device
Inventor: FUJIMOTO MOTOAKI
IPC: F23N5/24
Filed: 1987-07-20
Abstract: PURPOSE:To enable detection of even disconnection of a feed cylinder or an extension pipe thereof, by a method wherein the base end part of a feed and exhaust cylinder is coupled to a burner body, end the connection metal of a lead wire guided from the burner body side is linked to a coupling part between the feed cylinder and the feed and exhaust cylinder or the extension pipe. CONSTITUTION:When an exhaust cylinder 7, an extension cylinder 9, a feed and exhaust cylinder 3, an extension pipe 8, and feed cylinder 6 are not disconnected, a closing circuit 35 for detecting disconnection is charged with a current, a signal provided on a signal line 38 produces an L level, and it is decided that a microcomputer 39 is normal. For example, when coupling parts 29 and 27 between the extension pipe 8 and the feed cylinder 6 are disconnected, electrical connection between an annular metal 22, securely pressed in and engaged with a coupling part 27 of the feed pipe 6 and a coupling part 29 of the extension pipe 8, is disconnected. Since no current is supplied to the closing circuit 35 for detecting disconnection, a photo transistor 36 of a photocoupler 30 is turned OFF, and a signal provided on a signal line 38 is shifted from an L-level to an H-level. Thus, the microcomputer 39 informs that the feed and exhaust cylinder is disconnected.

Abstract: PURPOSE:To calculate an accurate current position by taking into consideration a time lag from receipt of a GPS signal to the end of operation for position measurement, and making a correction for an estimated current position with the current position calculated by a GPS position measurement method. CONSTITUTION:A computer 2 operates a travel locus on the basis of a travel distance and a travel direction detected from the output signals of a travel speed sensor 1 and a gyroscope 4. The travel locus and a road map in a CD-ROM 5 are collated with each other, and an estimated current position and travel route are calculated by an estimated navigation method. The result is corrected by use of a current position and travel direction obtained from a GPS receiver 3 via GPS position measurement. In this case, a time lag from signal receipt to current position output (time for travel up to a position of a1-a2) is inputted from the receiver 3, and an estimated prior position b1 corresponding to the time lag found through the estimated navigation method is read out for correcting a position C1 obtained from current GPS position measurement. In addition, an estimated position (b11-b13) and b2 are read from the receiver 3 and the estimated current position b2 is updated, using the latest position C2 obtainable through the re-calculation of each estimated position after the position C1 as reference.
