Abstract: PURPOSE: To make it easy to load and unload a tape while simplifying a head mechanism by moving a vertical magnetization type head, consisting of a main magnetic pole and subordinate magnetic pole, and a reproducing head in a tape- width direction by a common feed mechanism and by moving the subordinate magnetic pole in a tape thickness direction.  
     CONSTITUTION: The magnetic head consists of main magnetic pole 21, subordinate magnetic pole 22, reproducing head 30, etc. Those three heads are fitted to head moving table 43 of common head feed mechanism 40. Through the step rotation of pulse motor 41, male screw 42 and female screw 44 are turned, and consequently moving table 43 moves vertically to move heads 20 and 30 vertically in the width direction of tape 1. Subordinate magnetic pole 22, on the other hand, is fixed to driving shaft 47a of electromagnetic plunger 47 being movable in the thickness direction of tape 1. Consequently, the head mechanism is simplified and the tape can be easily loaded and unloaded.

IPC: G02F1/29
Filed: 1984-04-09
Abstract: PURPOSE:To form an electro-optical deflector which is excellent in a utilization efficiency of a high frequency band without using an optical contact which is difficult technically and unstable, by combining an electro-optical crystal of a simple shape and sticking an electrode layer of a simple shape to both its upper and lower faces. CONSTITUTION:Electro-optical crystals 1a, 1b forming a pair of rectangular parallelepipeds are cascaded and placed in a (y) axis direction along an optical path, and also an optical axis taken in a (z) axis direction is inverted. They are constituted and placed so that in the crystal 1a, the base of the triangle contacts to the eight side of the crystal and also the apex contacts to the left side, and in the crystal 1b, the base of the triangle contacts to the left side and also the apex contacts to the right side. As a result, a nearly constant electric field is generated in the crystal under the electrode, a variation of a refractive index is generated under such a constant electric field, and also between each adjacent crystal, the optical axis is inverted and set to each opposite polarity, therefore, for instance, when a variation of a refractive index generated under the electrode of the crystal 1a is denoted as Dn, a variation of a refractive index generated under the electrode of the crystal 1b becomes -Dn.

Abstract: PURPOSE:To realize the insulation of vibration in the foundation at low cost by a method in which the foundation is housed in a water tank, and air chambers divided into many sections and having openings on their bottoms are provided on the water-contact portions of the side and bottom of the foundation. CONSTITUTION:A foundation 1 is housed a water tank 3 built on the ground 2, where water 4 is filled up to the water level 5 and excess weight obtained by deducting buoyance from the weight of the foundation 1 is supported by a spring device 8. Air chambers 9 and 10 divided into many sections are provided on the water-contact portions of the sides and bottom of the foundation 1, and the bottoms of the air chambers 9 and 10 are opened. When the foundation 1 is displaced to the right, water in the right side of the foundation 1 passes through the openings 9 and 5 of the air chamber 9 to push up the water surface 11 of the air chamber 9, and thereby air in the air chamber 9 is compressed and the increase of the pressure is transmitted to the wall of the water tank on the right side. On the left side of the foundation 1, the opposite action takes place. The vibration of the foundation can thus be insulated by this way.

Filed: 1978-06-08
Abstract: PURPOSE:To safely and surely perform head loading and prevent accident by changing the number of revolutions of a spindle motor stepwise during the time until it is increased to the final steady number of revolutions in a magnetic disc. CONSTITUTION:The number of revolutions of a spindle motor 1 is detected in a circuit 2 and is compared 3 with the reference signal from a circuit 4, the result whereof is sent to a motor drive control circuit 5. According to the input of low-high speed switching signal HLS, the circuit 4 outputs the signal corresponding to the number of revolutions f1 up to the time t3 when the low speed region control ends from the power source input time to and outputs the signal corresponding to the number of revolutions f2 after the time t3. Further, according to the changeover of the signal HLS, the circuit 6 supplies the current i2 to the drive switching circuit 7 up to the time t3 and does so after increasing the same to the current i1 after said time. This results in that the motor 1 receives two stages of changes B in the number of revolutions until it attains the steady number of revolutions.

Abstract: PURPOSE:To select a logical output in a resetting period optionally by connecting an additional circuit which has high output impedance during the resetting period to the output side of the output port register of a logical output impedance IC. CONSTITUTION:When a reset pulse RS is supplied to a terminal 6 after power-on operation, a data signal DT is supplied from a computer 1 to the input register 3 of a latch IC2 for extension, but it is not transferred to the output register 4. The Q output of an FF circuit 9 is on a level L, so the respective NAND circuits 10 and NAD circuits 11 of logical circuits 8 (i=0-n-1) of the additional circuit 7 are closed and the outputs of the circuits 10 and 11 are on the levels H and L respectively. Therefore, MOSFETs 12 and 13 are both off and high output impedance is obtained at each terminal T3; and terminals connected to a power source B through a resistance 11 or grounded are on the levels H and L respectively and terminals in a floating state sill have the high impedance. Output terminals 10n and 10n+1 are set on the level H or L optionally.
