In an optical disc 7 and an optical disc recording apparatus wherein a desirable information signal is recorded in a recording area of the optical disc 7 in which data such as musical number, starting time, ending time and so on based on the information signal recorded in the recording area of the lead-in area AR.sub.RI, in addition to the recording area of the optical disc 7, extended recording areas AR.sub.EXI and AR.sub.EXO are provided at inner and/or outer peripheral sides outside of the recording area and desirable recording informations are recorded in the extended recording areas AR.sub.EXO and AR.sub.EXO .
摘要:
The optical disc according to the present invention includes an unrewritable region in which the number of times of possible recording or the cumulative possible recording time duration is recorded in advance. The apparatus for recording signals on this optical disc according to the present invention reproduce the number of times of possible recording or the cumulative possible recording time duration recorded in the unrewritable region of the optical disc and inhibits the recording operation when the number of times of recording or the cumulative recording time duration exceeds the aforementioned number of times of possible recording or the cumulative possible recording time duration.

This invention provides a fluid control device capable of making compact a fluid control device in which a valve and a limit switch are combined. A valve 6 includes a piston 26 as a moving member which includes a protruding portion protruding from an opening of a casing 21, and which linearly moves according to opening and closing of the valve 6 so as to abut against a limit switch 7. The limit switch 7 is made to face the piston 26 and is attached via a limit switch positioning unit 8 so as to be adjustable about its position. The limit switch positioning unit 8 includes a first bolt 42 fixed to a body 2, a second bolt 43 fixed to the limit switch 7, and a connection screw 44 which connects both the bolts 42, 43. The first bolt 42 and the second bolt 43 have different pitches from each other.

A front-wheel speed is calculated as a wheel speed of driving wheels, a rear-wheel speed is calculated as a wheel speed of driven wheels, a rear-wheel acceleration is calculated as a wheel acceleration of the driven wheels, a front-wheel-speed difference value is calculated as a driving-wheel-speed difference value, a rear-wheel-speed difference value is calculated as a driven-wheel-speed difference value, a rear-wheel-acceleration difference value is calculated as a driven-wheel-acceleration difference value, and a front-wheel ground load is calculated as a ground load acting on the driving wheels. Based on these calculated values, a gradient of a tire-characteristic curve indicating an amount of change in road-surface friction coefficient with respect to an amount of change in slip rate is calculated, and the calculated gradient of the tire-characteristic curve is compared with preset threshold values, whereby a road-surface friction coefficient as a road-surface condition can be determined.
摘要:
A method for manufacturing a high-strength motor vehicle door hinge from a steel plate blank includes a cold heading step of forming a cylindrical bulging portion at one end of the blank in the width direction, a shaft hole forming step of forming a shaft hole in the cylindrical bulging portion, and a shaft hole finishing step. In the shaft hole forming step, a shaft hole is formed using a first punch having a top end with a shape of a cone and a first die having an inner wall with a gap volume relative to the outer circumferential surface of the cylindrical bulging portion of the blank.

A drill according to an embodiment of the present invention includes a body part and a cutting part with a cylinder-like shape. The cutting part includes two cutting edges located separately from each other at a front end portion of the cutting part, two flutes which are continuous with each of the two cutting edges and extend spirally toward a rear end portion of the cutting part, and a clearance which extends spirally from a side of the front end portion to a side of the rear end portion, and is recessed inward in reference to a periphery of the cutting part in a sectional view. The cutting part includes a first joining flute including at least one of the two flutes and the clearance being joined together. The first joining flute includes a bottom surface being outwardly protruding curve-like line in a sectional view. A method of manufacturing a machined product using the drill is also provided.
摘要:
Between a driving base operated by an air cylinder and a lever member fixed to a valve shaft integral with a valve plate, a connecting mechanism for connecting the driving base and a lever member, capable of displacement, and a cam mechanism for tilting the lever member are interposed, and a stopper mechanism for stopping the lever member at an opposing position of the valve plate or a full-open position, and after the lever member is stopped by the stopper mechanism at the opposing position or the full-open position, the lever member is tilted by the cam mechanism so as to incline the valve plate and to press a valve seal to a valve seat portion or a wall face in the periphery of an opening.
