Title: Information recording and reading device for optical card
Inventor: AOI TOSHIKI
IPC: G11B7/09
Filed: 1983-04-15
Abstract: PURPOSE:To facilitat the tracing control of an optical card at a guide part and enabling an optical head to detect the track of the optical card quickly and accurately, by distributing three laser beams vertically to the traveling direction of an optical head. CONSTITUTION:The laser beam sent from a laser device 30 is divided into three laser beams L, C and R by a beam splitter 31. When these beams are irradiated to an optical card, three laser spots are formed on the optical card. These three spots are distributed in the direction vertical to the traveling direction of an optical head. The center beam C is used mainly for reading control and focusing control; while left and right beams L and R function to control the tracking at the guide part of the optical card. When the beam C gets out of the center line, the laser spots L and R irradiate the surfaces of different reflection factors. Then a difference of detection output is produced between photodiodes pL and pR. In case the beam C gets out of the center line after it is guided by a track, a 2-plit photodiodes pc produes a difference of detection output. Then a differential amplifier 37 produces an output, and precise driving is given to a lens 33 by a lens fine driver 39. Thus the output of the amplifier 37 is set at zero.

Abstract: PURPOSE:To freely perform the stoppage or continuation of the supply of one elastic material, by providing an opening and closing mechanism, wherein the flow-out of an elastic material is controlled with the sliding of a core material guide, to at least one of the outflow ports of a first and second elastic materials. CONSTITUTION:A first cap 18 and a second cap 20 are contacted at a B-point to supply a first elastic material from a first supply passage 16 under a 'close' state while a second elastic material is supplied from a second supply passage 17a. Whereupon, the first elastic material is at first adhered to the surface of the core material 15 protruded from the passage 14 formed in a core material guide 13 and the second elastic material passing through the supply passage 17a and a communication hole 18a is adhered to the surface of said core material 15. During the above-mentioned operation, if the core material guide 13 is moved to the right, the first cap 18 connected and fixed to the core material guide 13 by a connection material 19 also similarly moves to the right and, therefore, the contact part at the aforementioned B-point between the first cap 18 and the second cap 20 comes to an 'open' state. As a result, the second elastic material supplied through a second supply passage 17b becomes possible to flow out.

Abstract: PURPOSE:To shift a columnar object toward the flange part side of a tapered roller and to rotate it in a positioned state by parallelly and horizontally arranging axial centers of a pair of tapered rollers each formed with the flange part at the terminal part on the small diameter side, and driving them in the same direction. CONSTITUTION:A pair of tapered rollers 10 are arranged freely rotatably in the state that their axial centers are horizontal and almost parallel with each other. In each of tapered rollers 10, the outer diameter dimension is continuously reduced along its axial center, and a flange part 10a is formed at the terminal part on the smaller outer diameter side. A columnar object 2 is placed on a pair of these tapered rollers 10 and when a pair of tapered rollers 10 are rotated in the same direction, the columnar object 2 is driven to be rotated by frictional force with the tapered rollers 10. Since the circumferential velocity of the tapered roller 10 on the larger diameter side is higher than that on the smaller diameter side, trust is exerted on the columnar object 2 in a direction shown by an arrow P and that object 2 is moved. Then, since it is stopped by the flange parts 10a, the columnar object 2 is rotated in contact with the flange parts 10a on a pair of tapered rollers 10.

Abstract: PURPOSE:To provide a clamping device for a mold, compact and light, by carrying out the mold opening and closing by pressurizing a mold closing chamber and a high speed mold closing chamber respectively and operating an on-off valve on the opening side only by means of a cylinder space. CONSTITUTION:High speed mold closing is carried out by feeding pressurizing oil into a chamber D in the state of mold opening. At that time, since the sum of effective pressurized area of a chamber B and a chamber C is is set almost equal to the effective area of a chamber A, the volume of oil discharged out of the chambers B and C and the volume of oil required by the chamber A are almost equal never to make the pressure inside the chamber A negative. The flow rate of pressurized oil fed to the chamber D is continuously reduced and the mold closing is carried out at low speed and low pressure, and then the chamber A is pressurized. As differential pressure is generated in front and in rear of an on-off valve 25 by said process, the ON-OFF valve 25 is moved forward and backward and the end face of its sleeve-shaped section 26 is brought into contact with a piston section 21 of a clamping ram to close a communicating line 22. The pressure oil fed to the chamber A thereafter acts on the rear end surface of the clamping ram 20 by the arrangement to carry out a powerful clamping. An injection device 17 is moved forward by dwelling in the state and molten resin is injected into a mold for the required molding.
