Title: Reel driving system for magnetic tape device
Inventor: KITAZAWA TADASHI
IPC: G11B15/58
Filed: 1979-05-11
Abstract: PURPOSE: To simplify the constitution and thus realize the cost reduction and the miniaturization, by supplying the current to the reel driving motor only in the tape take-up direction and then controlling the scale of the conduction current in order to change the intensity of the driving torque to the tension torque.  
     CONSTITUTION: Motor M and one unit of switch SW 1  are connected between the power sources, and switch SW 1  performs the ON/OFF control for the electric conduction to the motor. And no switching is given to the direction of electric conduction with only fixed direction set for the electric conducting direction. Thus the driving control is given to the reel by changing the scale of the driving current. In other words, the intensity is changed for the take-up driving torque to the torque of the tape lead-out direction which is expressed by the product of tape tension S and tape turn radius r. Thus the switch suffices with one unit for each reel, thus decreasing greatly the number of component parts as well as the space. As a result, the cost reduction and the miniaturization can be realized.

IPC: H01L29/72
Filed: 1979-05-11
Abstract: PURPOSE:To obtain a semiconductor device having high performance by isolating n- type low density mesa type region via p-type layer into upper and lower layers, coating the peripheral edge in insulation and generating a drift current substantially in balance with diffusion current dut to minority carrier in the upper layer. CONSTITUTION:An n-epitaxial layer 11 is formed on an n<+>-type silicon substrate 10, a Si3N4 mask 12 is formed thereon, the layer 11 is selectively etched to form a mesa type region. Then, a thick oxide film 13 is formed, B ion is implanted to the portion excluding the mask 12 to form a p-type base layer 14. P is diffused in the upper layer 11b to form an n<+>-type layer 15 as an emitter electrode pickup layer. A collector electrode 10 is formed at the n-type substrate 10, and a base electrode is formed at the layer 14. Since the emitter is low density, the minority carrier diffusion distance is larger than the emitter thickness, an n<+>n and pn-junctions are formed in the emitter layer to form an electric field for producing a drift current balanced with the diffusion current of the minority carrier in the emitter to increase the gain and to enable low noise and high withstand voltage.

Abstract: PURPOSE:To allow the easy and sure completion of loading to a camera by making the cumulative paper thickness in the front end part of light shielding paper to be inserted into a spool slit larger than the paper thickness in the part deeper than a folding seam. CONSTITUTION:The detaining force between the front end of the light shielding paper and the spool slit 11 is generated as the friction resistance to the winding force is generated as the permanent set of winding when the film is wound as a roll time, is stuck with sealing paper and is prevented from releasing appears as a curl at the time of use and the spring elastic forces thereof come into contact and pressing with each other at least at two points between the spool slit 11 and the front end part of the light shielding paper. The place where the spring elastic force is necessary is the place from the front end of the light shielding paper to the folding line 6. The light shielding paper made of the material which is the same in the modulus of elasticity but has a larger thickness in the above-mentioned front end part is used. The detaining force of the roll film for photography to the spool is greatly improved and stabilized.

Abstract: PROBLEM TO BE SOLVED: To put an opening of a vinyl bag into a state opened previously so as to heighten openable property by folding back a part of at least a sheet of a doubled opening to the outside so as to give a foldable way, putting the opening into a state opened previously, and punching it with a fold-back line as a symmetry line. SOLUTION: A vinyl bag 1 comprises a barrel body 2. Both end parts 7 of an opening 6 formed of two-layer sheets 4 and 5 which form the barrel body 2 are cut off at a predetermined length. Although cutting lengths of the end parts 7 are optional, either the sheet 4 or the sheet 5 is folded to the outside. It is pressed to an extent that the folded state does not return to the original state so as to give a foldable way. A hole is punched with a folded line 8 to be generated when one of the film is folded back as a symmetry line. Thus, by returning the folded part to the original state, a conventional handle is produced. In this tote bag, as the opening is already being curled up in a static state, articles can be housed in it by holding the bag single-handed, so that easy-to-use property can be improved.

Abstract: PURPOSE:To prevent the occurrence of an error equivalent to the pulse width of an encoder even when a reference point is decided in either forward or reverse direction by moving a work in the forward or reverse direction based on the work starting position. CONSTITUTION:A work position reading means 17 is provided to read the posi tion of a work 6 via a potentiometer 19 and a microcomputer 9. Then the forward or reverse revolving direction of a motor 7 is decided on the present position of the work 6 centering on an original point. At the same time, the signals SEL of different levels are produced. A pulse switch means 18 is pro vided at a precedent position of a reference point detection means 4. Then, a signal INT is set at 'H' at the rise of a pulse phiZ produced by an encoder 12 as long as the signal SEL is kept at 'L'. Meanwhile the signal INT is set at 'L' at the rise of the pulse phiZ when the signal SEL is kept at 'H', respec tively. Thus, an interruption latch 14 is actuated. As a result, a reference point is detected by the first pulse phiZ after the work 6 passed through the original point. Thus, the reference point is quickly detected within a single revolution of the encoder 12 regardless of the forward or reverse revolution.
