Patent JP-H01170118-A (JP)
Title: Digital pll circuit
Inventor: II HIROSHI
IPC: G11B20/10
Filed: 1987-12-24
Abstract: PURPOSE:To compose a PLL circuit corresponding to the modes of both sides by switching decoders to a reproducing device to have different speed modes. CONSTITUTION:When a phase difference signal between an input signal and a PLL clock is detected, the phase difference signal is decoded by first and second decoders 10a and 10b, and it is loaded as the value of the frequency- dividing ratio of a frequency-divider 12 generating the PLL clock. Here, the first and second decoders 10a and 10b are switched by a data switching device 11 to those in which decoding characteristics are different according to the speed mode of the input signal. For example, in a DAt, the first decoder 10a is selected which corrects the frequency-dividing ratio so as to be made large when a phase dislocating quantity is large and which corrects the frequency- dividing ratio so as to be made small when the phase dislocating quantity is small in a normal mode to execute an ordinary reproduction. Since the fluctuation of the speed is large in a search mode, the second decoder 10b is selected which executes a correction in the frequency-dividing ratio to be approximately proportionate to the phase dislocating quantity.

Title: Display device
Inventor: FUJII TERUSHI
IPC: G09F9/00
Filed: 1989-12-18
Abstract: PURPOSE:To prevent external contact with a display and signal conductors and to ensure a stable display operation over a long period by freely closing the opening of a guide groove, along which the display device freely moves, with a cover. CONSTITUTION:By moving the display device 1 to the right and left by opening the cover 42, the display 1 is guided along the side wall 44 of the guide groove 45 without exposing the signal conductors 50 and 51 outside; consequently the position where the display 1 is fixed can be altered. By reclosing the cover 42 after that, external contact with the display 1 and signal conductors 50 and 51 is interrupted. Thus, the display 1 and signal conducts 50 and 51 are not exposed outside, and high reliability can be maintained over a long period.

Title: Ac miniature motor
Inventor: YAMANAKA HAJIME
IPC: H02K3/04
Filed: 1994-12-02
Abstract: PURPOSE: To reduce the thickness of a motor by arranging a coil, comprising a large number of mutually continuous loops, along one imaginary plane while shifting the position of each loop sequentially along that loop to obtain a sheet- like structure for forming a stator coil. CONSTITUTION: When an AC current is fed to the coil A2 of a stator A, magnetic flux is induced in the coil A2 and a rotor B is rotated. The coil A2 comprises a large number of mutually continuous loops each arranged along one imaginary plane P2 while being shifted sequentially. Since a sheet-like structure is employed, a quite thin motor can be realized. With such structure, radial thickness of the stator A can be reduced and thereby the thickness of motor can be reduced.

Title: Transformer device
Inventor: FUJII ATSUSHI
IPC: H01F19/04
Filed: 1989-12-19
Abstract: PURPOSE:To reduce the number of component parts needed, and to obtain a transformer device with which manhours can be cut down in the manufacturing process by a method wherein a plurality of protrusions are formed along the longitudinal direction of the band-like region on both side face parts of an insulating film to be wound between windings of each layer, and the insulating film is wound with the surface having the protrusions facing outside. CONSTITUTION:Embossed insulating films 9a and 9b are wound with the protruding side of the embosses 10 facing outside. When the embossed insulating film is wound, the insulating film is in the state that the embosses 10 are protruding to outside when the film is wound on a bobbin. When a lead wire is wound thereon, it is wound on the center part, namely, on the part pinched by two embossed parts. As a result, the lead wire is prevented from squeezing out to outside by the embosses 10 protruding to both sides, and the embosses work as a mean of positioning of the winding. Accordingly, the barrier heretofore in use is unnecessitated, and the number of component parts used can be reduced.
