Title: Reproducing device
Inventor: SAKAKIBARA YOSHIO
IPC: G11B15/467
Filed: 1991-05-22
Abstract: PURPOSE:To provide the reproducing device capable of conducting smooth frame synchronization. CONSTITUTION:A drum 2 outputs a regenerative signal by rotating and scanning a built-in head against a tape. A tracking control means 4 fixes each head scanning and tracking signal by the prescribed correspondence relation. A frame phase difference detection means 6 detects the phase difference between the regenerative and reference frames extracted by the regenerative signal. A phase correction means 7 performs the optimum phase correction from the value of the frame phase difference and takes the synchronization between the reference and regenerative frames. As the correction is performed by the optimum pass so as to maintain the correspondence relation of the head scanning and tracking signals after the frame phase correction, the frame synchronization can be completed in a short time.

Title: Winding device for axial direction void type rotary electric machine
Inventor: KOMATSU KIHACHIROU
IPC: H02K15/06
Filed: 1979-09-14
Abstract: PURPOSE:To insert coils into slots easily under stable conditions from a bobbin by a mechanism wherein the one portions of the bobbin are extended in the slot direction from the surfaces of the slot inlets of a ringed core, and the coils are dropped into the slots along the extending portions. CONSTITUTION:Extending portions 34, 35 which partially extend in the slot 2 direction only by dimensions which the wire diameters of wires 5 and the number of the wires simultaneously wound are considered are formed to the lower end portions of a bobbin 4 and an end plate 7, and coils 3 are let fall into slots 2 along the extending portions 34, 35. Thus, when inserting the coils 3 wound to the bobbin 4 into the slots 2 by means of a scraping-off frame 6, the coils 3 do not spring outside the slots 2 even when the coils 3 float or cross due to spring-back because the coils are inserted under conditions that are sufficiently lowered up to insides more than the inlets of the slots 2. Consequently, the coils can easily be inserted into the slots under stable conditions.

IPC: G01C21/00
Filed: 1989-05-11
Abstract: PURPOSE:To automatically display a starting point at the time of the next running by storing a starting place, and displaying map data of the periphery of the corresponding starting place, in the case a running locus stored newly coincides with a running locus stored already. CONSTITUTION:When an engine switch 7 is turned off, the present running locus is stored in a running locus memory 8. A collator 9 detects the end point from the present running locus, sets this point as an origin, allows it to coincide with an origin of the previous running locus B fetched from the memory 8 and compares both the loci. When both the loci coincide with each other within an allowable range, a coincidence signal is sent to a starting place memory 6. The memory 6 sends a starting place B corresponding to the locus B to an indicator 4. Subsequently, when the switch 7 is turned on, the indicator 4 fetches map data of the periphery of the starting place B from the road map data 3, and displays the starting place B in the center of the screen. In such a way, several starting places are stored in advance in the memory 6, and in the case the locus before running is ended coincides with the running locus corresponding to these starting places, the starting place is displayed automatically.

Filed: 1991-05-23
Abstract: PURPOSE:To make an operating frequency high and to improve sensitivity by a method wherein a voltage approximating to a subgap voltage at which an intermediate frequency output becomes maximum is applied as a bias voltage on a Josephson junction prepared by connecting two superconductor electrodes weakly by a normally conductive metal or a superconductor metal. CONSTITUTION:A Josephson junction 1 is prepared by disposing two superconductor electrodes 10 and 11 with an insulating layer 12 interposed and by connecting them weakly by a layer 13 of a normal conductor metal or a superconductor metal. In order to take in an input signal sufficiently without making it be reflected by the Josephson junction 1, the Josephson junctions 1 in the number being necessary for attaining an impedance matching are connected in series. When a bias voltage approximating to a subgap voltage is applied on the Josephson junction 1, a current due to multiple Andriev reflection is generated, the two superconductors 10 and 11 are put in a state of conduction between them and an intermediate frequency output becomes maximum in a negative differential resistance region near the subgap voltage. For a bias voltage source 2, a voltage source of low internal impedance is used. In this way, a heterodyne detector of which the operating frequency is high and which has excellent sensitivity is obtained.
