Title: Redundant system path monitor
Inventor: NISHINE KOSUKE
IPC: H04L1/22
Filed: 1995-01-23
Abstract: PURPOSE: To prevent occurrence of errorneous path alarm at changeover of a clock supply section without extending a scale of a transmitter even when number of contained transmission lines is increased in the redundant system path monitor monitoring a path of a cross connect section of the transmitter having a redundant system. CONSTITUTION: A 1st prescribed pattern and a 2nd prescribed pattern are inserted alternately to a transmission signal by a prescribed timing signal and the result is outputted to a confirmation means 4. The confirmation means 4 confirms the accurate arrival of a transmission signal based on the pattern inserted to the transmission signal to confirm it that occurrence of a path error in the transmission line is not caused. A timing signal generating means 5 is provided with a redundant configuration and when the active means is switched to the standby means, a mask signal generating means 6 generates a mask signal over a prescribed time from the switching point of time and a confirmation inhibit means 7 inhibits a confirmation operation of the confirmation means 4 while the means 7 receives a mask signal.

Title: Superconduction storage circuit
Inventor: HASUNUMA MASAHIKO
IPC: G11C11/44
Filed: 1989-01-17
Abstract: PURPOSE:To simplify circuit constitution and to attain high speed processing of the circuit by connecting both terminals of 1st and 2nd superconducting lines whose critical current value differs and connecting a conduction path to both connecting parts. CONSTITUTION:A superconducting loop 1 is formed by connecting the 1st and 2nd superconducting lines 1a, 1b with a different critical current value and paths 2, 3 are connected to both end connection parts 6, 7 of the 1st and 2nd superconducting lines 1a, 1b.

Title: Ic card reader/writer
Inventor: HONDA IKUFUMI
IPC: G06K17/00
Filed: 1990-01-19
Abstract: PURPOSE:To improve the reliability for transfer of information to an IC card by selecting a mode capable of cancelling a positioning lock state or a made incapable of the cancelling is a knob pressing operation enable state via the electrical control. CONSTITUTION:The selection is attained via the electrical control between a mode where a positioning lock state can be cancelled in a pressing operation enable state of a knob 29 and a mode where the positioning lock state cannot cancelled. In other words, a lock cancel lever 33 is kept inactive via the electro magnetic attraction as long as the information is transferred to an IC card. Then an operation part 26 moves forward with the forward moving operation carried out with push of the knob 29. Under such conditions, the extended output end of an elastic member interlocking the part 26 has only the elastic deformation against the energizing force of the elastic member and the lever 33 has no rotation at all. Therefore the rotational action is not transmitted to a positioning means 27 either. Thus it is possible to prevent the cancel of an interlock state and the breakage of the interlock mechanism that are caused by the misoperations of a positioning action cancelling mechanism.

Title: Air pressure utilizing paper sheet transportation device
Inventor: UEDA YOSHIRO
IPC: G03G15/00
Filed: 1986-01-17
Abstract: PURPOSE:To prevent defective transportation, by providing a pressure regulating member for making the negative pressure of a paper sheet sucking unit for a small size paper sheet transportation region smaller as compared with the negative pressure of a paper sheet sucking unit for a large size paper sheet transportation region so as to suck paper sheets securely. CONSTITUTION:A transportation box 1 is divided into 3 regions by resistance bodies 12, 13, and 14, i.e., a 1st region R1 for small size paper sheet transportation adjacent to a suction port 9 and a 2nd region R2 and a 3rd region R3 for large size paper sheet transportation. Therefore, when air is sucked through the suction port 9, the air in the 2nd region R2 moves to the 1st region R1 through a gap S1 and then discharged to the outside of the transportation box 1. The air in the 3rd region R3 moves to the 1st region R1 through a gap S2 and then discharged to the outside of the transportation box 1. In the state that a paper sheet 6 is stopped by a paper sheet stopper 7 the paper sheet 6 positions at the 1st region R1 for small size paper sheet transportation. At the time, the negative pressure spreading over the rear side of the paper sheet 6 is made smaller due to the action against ventilation of the resistance bodies 12, 13 and 14.

Title: Clamp rotation mechanism for information recording medium
Inventor: ODA KEIJI
IPC: G11B17/028
Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To reduce the cost through omission of force-fitting work and utilization of an inexpensive magnet by forming a rotor part by press work, joining this part integrally with a turntable by welding and utilizing the magnet of a low magnetic flux density. SOLUTION: The rotor part 30A is formed by drawing press work. First, a step part 37 is extended in the outer circumferential direction from an upper part of a cylindrical shaft part 33 to be freely rotatably inserted into a bearing 21 on the side of a stator, and moreover, a bent part 34 bent downward the part 37 is horizontally extended. The lower surface side of the turntable 25 and the lower surface side of a clamper magnet 26a are joined to the bent part 34 by welding. Moreover, a yoke part 30a, to which a rotor magnet 29 is fixed, is provided orthogonally to an outer circumference of the turntable 25. The magnet of a low magnetic flux density is utilized for the clamper magnet 26a as in a discoid shape with no center hole. Consequently, the force-fitting work of a hub onto a spindle can be omitted, thus facilitating the alignment of their axial centers.  In addition, the inexpensive magnet can be utilized, and the cost can thus be reduced.

Title: Control device for continuously variable transmission
Inventor: ONAKA TORU
IPC: B60W10/10
Filed: 1986-01-17
Abstract: PURPOSE:To enhance an acceleration response characteristics while ensuring a suitable acceleration feeling in rapid acceleration time or the like of an engine, by controlling speed change ratio of a continuously variable transmission not to perform a change correction of the speed change ratio but to change its changing speed itself for when the engine is in normal operation, for instance when the engine is rapidly accelerated. CONSTITUTION:As an accelerator opening rapidly increases by a kickdown control, also a target value of an input speed of a continuoulsy variable transmission (CVT) mechanism 50 rapidly increases. And a speed change ratio control means 109 performs a shiftdown control of speed change ratio of the CVT mechanism 50 so that an actual input speed agrees with said increased target value. Simultaneously, a target value rapid increase time detecting means 110 detects a rapid increase of the target value to be input to a control correcting means 111, and a shiftdown control gain of the speed change ratio is increased and corrected from that in normal operation time. And the input speed of the CVT mechanism 50 is quickly increased to the target value, reducing a time for reaching the target value. In this way a good acceleration feeling matching with an accelerator control can be obtained by enhancing an acceleration response characteristic.

Filed: 1979-01-29
Abstract: PURPOSE: To bond dissimilar metals without impairing their mechanical strength by so radiating an electron beam as to melt only one metal and melting the other metal with the high temperature of the molten part in lap welding of said metals.  
     CONSTITUTION: An electron beams is radiated from the direction of 3 to two kinds of metals 1 and 2 to be welded. The molten part 4 by the electron beam is formed only on the upper metal 1 to be lap-welded. A part between the two metals 1, 2 are mutually fusion-welded by making use of the high temperature layer 5 formed around the molten part 4 of the electron beam. Since this method does not cause mixing of mutual metals, bonding is accomplished without impairing their mechanical strength and the bonding of dissimilar metals of relatively poor weldability is made possible.
