Inventor: ORUKAWA MASAHIRO
IPC: G11B7/00
Filed: 1990-05-17
Abstract: PURPOSE:To increase a power margin at the time of recording by binarizing a regenerative signal after differentiating plural times. CONSTITUTION:The regenerative signal to be obtained by reproducing a recording pattern is inputted to a differentiation circuit 11, and a gate signal to be obtained from a regenerative waveform of an output of the differentiation circuit 11 after differentiating one time by comparing it with a reference signal set previously as a positive value with a comparison circuit 13, a gate signal to be obtained by comparing a reference value set previously as a negative value with a comparison circuit 14 and a signal waveform to be obtained by a differentiation circuit 12 after differentiating two times are obtained. Afterward, timing of the rise and the fall of the signal waveform after differentiating two times is detected by using zero cross detecting circuits 15 and 16, and a regenerative waveform after binarization is obtained by a binarization circuit 17. By this method, since inversion timing for the purpose of binarization becomes an inflection point of the regenerative signal, the power margin under mark edge recording is enlarged.

IPC: G06F15/16
Filed: 1985-06-13
Abstract: PURPOSE:To confirm accurate reception of a frame sent from the primary station to the secondary station quickly by managing a reception sequence number in the secondary station not by a host computer but by a network channel. CONSTITUTION:The network channel 4 in the secondary station 3 uses a reception processing section 5 to receive each frame sent from the primary station and the information is transferred to the host computer 10 via a sub channel 8. When the reception processing section 5 receives one frame from the primary station especially, the section 5 extracts a transmission sequence number N(S), adds '1' to produce the sequence number R and stores it in a reception sequence number storage section 6. A transmission processing section 7 combines the information requested for transmission from the host computer 10 via the sub channel 9 into frames and sends the result to the line 2. The transmission processing section 7 extracts the sequence number R from the reception sequence number storage section 6 when the P-bit of reception confirmation reply is logical '1' in the S frame especially and sets the number to the reception sequency number N(R) of the S frame.

Moreover, the thickness of the barrier layer 23 is made s, and the thickness of the diffraction grating layer 2b is made t. Hereupon, the relation between s and t is s>t. The diffraction grating layer 2b in the region ls in length at and around the center of an element is removed. Thereafter, a uniform diffraction gating pattern is formed by two-beam interference exposure method, etc., and etching is done so that the depth may be not less than t and not more than s by chemical etching, etc., so as to form a diffraction grating 3 for distributed feedfack. And further, a clad layer 6 and a contact layer 7 are crystal-grown. Since the barrier layer 23 and the clad layer 6 are of the same composition, parallel stripes of a diffraction grating layer 4 do not exist in a phase shift region. Lastly, a p-electrode 8 and an n-electrode 9 are formed, and reflection preventive films 10 are formed at both ends.

Abstract: 1402337 Shoe-drum-brake wedge actuators GIRLING Ltd 9 Nov 1973 [18 Nov 1972] 53405/72 Addition to 1255141 Heading F2E The Specification of the parent Specification 1,255,141 describes and claims an internal shoe drum brake actuator comprising a housing 10 formed with an internal chamber 16 and a pair of aligned bores 12, 14, opening from opposite sides of the chamber, a tappet 18 or 20 in each bore, the inner end of each tappet 18 or 20 being slotted and having mounted in its slot a roller 22 of greater diameter than the tappet, a wedge member 26 displaceable between the inner ends of the tappets and, in operation, bearing on the rollers, and a slot 30 in the housing 10 at the inner end of each bore 12 or 14 to accommodate the spreading movement of the rollers 22 resulting from a brake-actuating displacement of the wedge member 26. The present invention is characterized by one or both of the following features: (a) the wedge member 26 is restrained by the tappets from movement relative to the rollers in a direction generally parallel to their axes; (b) each of the sides of the housing intersected by the roller axes has a single access opening at or adjacent to the centre of the side (to permit attachment of the rollers to the tappets). As shown, the sides forming the slot of each tappet are extended as at 36 beyond the roller to flank and guide the wedge member 26; thus the slotted end of each tappet receives both the wedge member 26 and the respective roller 22. Alternatively, each tappet may have a projecting portion on one side only of its slot and extending over the full width of the tappet, the projecting portions of the two tappets projecting across opposite sides of the wedge member. Access opening 44, Fig. 2, (which is a vertical median section on a reduced scale), is for the introduction of each pin 24, in turn, on which a roller is to be mounted, while smaller opening 42, Figs. 1, 2, is for introduction of a drift to drive out pins 24 on dismantling.
