Title: Semiconductor memory device
Inventor: YAMADA KATSUYUKI
IPC: G11C11/416
Filed: 1979-06-01
Abstract: PURPOSE:To realize the high-speed reading by selecting the bit line group of the memory cell of matrix formation via the bit line group driver and the intragroup bit line via the bit line driver respectively. CONSTITUTION:The selection is given to the bit line groups composed of bit line B1 formed with two bit lines B1a and B1b which are selected by bit line group selecting driver BD2 and via load resistance R1 and R2 plus selection switch SW1 according to the output of current switch CS and bit line B2 formed with two bit lines B2a and B2b which are connected together with resistances R1 and R2 plus lines La1 and La2 and then selected by switch SW1 each. And bit lines B1 and B2 within the groups are selected via intragroup bit line driver BD1. Then memory cells M11, M21, M12, M22 and others are selected. The memory cells corresponding to other bit line groups are selected in the same way. In such constitution, both the length and the number of the bit lines to be connected are reduced for lines La1, La2, Lb1, Lb2 and others along with the floating capacity reduced. As a result, the high-speed reading is possible even for the high-density cell.

Abstract: PURPOSE: To provide a function of a light isolator or the like without loss even for the non-polarized light propagating in optical fibers by the constitution wherein a rotatory polarization crystal plate and a member having Faraday effect are disposed between two sheets of parallel double refractive crystal plates.  
     CONSTITUTION: A λ/2 plate 16 and a member 17 having Faraday effect are disposed between two sheets of crystal plates 12, 13 which comprise forming double refractive crystals to parallel flat plates in such a manner that their optical axes incline to the surfaces. Non-polarized light 10 coming from left is separated to the light having mutually perpendicular polarizations within the double refractive crystal plate 12 and their planes of polarization are rotated 45° to right by the rotato ry polarization crystal 16, after which they pass through the plate-form material 17  having Faraday effect then through a crystal plate 13, whereby two rays are made  to one ray. Conversely, it turns out that the non-polarized light 11 coming from  right is finally separated to two lengths of light from the two points differing from  the incident point of the light 10 of the crystall plate 12 and is then emitted, thus  the device has a function as an isolator.

Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To easily control a tape cassette by providing a memory element to a tape cassette and allowing the element to store the amount of tape running and a recording inhibit section information and the like. SOLUTION: A memory element 6 is embedded to the rear surface of a cabinet of a tape cassette 1 and this memory element is then connected to a microcomputer 15 for controlling operation of a deck via a plurality of connecting terminals 7 and conductive films 12. Upon completion of recording and reproduction, the microcomputer 15 causes the memory element 6 to store the count value of the tape running of a counter 19. When the tape cassette 1 is loaded to a deck for recording and reproduction, the count value is set to the counter 19 to display amount of tape running on a display panel 18. Moreover, since the recording inhibit section information of tape cassette is stored in the memory element, it is prevented that an important recording in this section is erased erroneously. As explained, effective use can be realized by embedding the memory element in the tape cassette.
