Title: Magneto-optical disk
Inventor: YAMAMOTO RYOICHI
IPC: G11B11/105
Filed: 1986-10-17
Abstract: PURPOSE:To give nearly the same ability to record to a disk inner periphery and a disk outer periphery by providing a magneto-optical recording layer with such a gradient in terms of layer thickness that the thickness of an inner layer of a disk is smaller than that of a outer layer of the disk. CONSTITUTION:As for a magneto-optical disk 1, the magneto-optical recording layer 3 is formed on a circular substrate 2 made of a doughnut-like transparent plastic, and the recording layer 3 is made of an amorphous rare earth metal transistion metal. As for the gradient of the layer thickness, the outer layer thickness dout is smaller than the inner layer thickness din. When a distance rin between the center O and the inner-most periphery 3b of the recording layer is half a distance rout between a center O and the outer-most periphery 3a of the recording layer, the length of the outer-most periphery 3a corresponding to a prescribed angle theta and the length of the inner-most periphery 3b meet 2:1. If an angular velocity constant system is used, the linear velocity of a light beam on the outer-most periphery 3a and that on the inner- most periphery 3b meet 2:1. In terms of the quantity of received light energy per unit area of the recording layer 3, the outer-most periphery 3a comes to '1', while the inner-most periphery comes to '2'. Thus the quantity of light energy per unit volume on the outer-most periphery is the same as that on the inner-most periphery.

Title: Synchronous storage device and data reading method therefor
Inventor: NODA KAZUYUKI
IPC: G11C11/41
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To reduce a reading cycle time by comparing the reference voltage line potential applying the potential during a bit line pair activation with the bit line pair potential previously discharged to zero, and making the 'high' of the input clock signal to a precharge circuit forcibly into the 'low' when the two potentials become equal to each other. SOLUTION: If a clock 12 is in an L period, an output 52 of a comparator 51 is set to L. If the clock 12 becomes H, the output 52 becomes L until an IO signal 45 and a signal 46 of a reference voltage line 22 become a same potential. On the other hand, during this period, an internal clock 81 is set to H and bit lines 4 and 5 are charged up. If the signals 45 and 46 become a same potential, the comparator 51 outputs the output 52, which is H, the clock 81 is forcibly made into L even though the clock 12 is H and it is transitioned to a reading operation. Thus, an H period of the clock of the input to a precharge circuit 7 is internally controlled, changed to an absolute minimum and the reading cycle time is reduced.

IPC: G02B6/12
Filed: 1990-09-19
Abstract: PURPOSE:To easily form a thin film by interposing a transparent electrode and/or a buffer layer between electrodes consisting of an opaque insulating substance and acting as a function for the change of refractive index which is generated in an optical film in the case of impressing voltage on the electrode. CONSTITUTION:An organic non-linear type optical film 4 is the crystal of a light deflecting element and consists of a thin film whose thickness (d) is <=100mum. The electrodes 5 and 6 are formed on both sides of the optical film 4, and if the electrodes 5 and 6 are opaque to use light, the buffer layer consisting of the insulating substance which is transparent to the light is interposed to form the electrode. When the voltage is impressed between the electrodes 5 and 6, the refractive index of the optical film 4 is changed and light advancing straight is deflected by an angle theta. Since the organic non-linear type optical material is easily made into the thin film, the deflection angle thetais made large. Then, a scanning device is miniaturized and the device which is not provided with a movable part is realized, then the service life of the device is made longer, the assembling and the adjustment thereof are simplified.

Title: Digital information processing device
Inventor: ARAI TAMOTSU
IPC: G06F1/00
Filed: 1984-11-26
Abstract: PURPOSE:To reduce power consumption and to save number of external terminals and externally mounted components by using a PLL circuit taking a low frequency signal as a reference frequency signal so as to form a high frequency signal thereby generating a clock signal in a high frequency for the information processing. CONSTITUTION:An output of an oscillation circuit OSC is utilized as a reference frequency signal of a PLL circuit constituting a clock generating circuit CPG. That is, the oscillated output is fed to a phase comparator circuit PD via a NOR gate circuit G1 and an output of an oscillation circuit VCO whose frequency is divided by a prescaler PSC is fed to the circuit PD. An output signal of the circuit PD controls the VCO via an LPF. The oscillation frequency of the VCO is phase-locked at a high frequency to the reference frequency of the OSC in the PLL loop. In order to save power consumption of the circuit CPG, the operation of the PLL circuit is made intermittent. Thus, the positive feedback loop of the VCO is cut off by the output of a gate circuit G2. Further, the supply of the reference frequency signal to the circuit PD is controlled selectively by using the circuits G2, G1.

Title: Semiconductor memory
Inventor: OKAMURA YOSHIFUMI
IPC: G11C11/413
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of the parallel test of plural cells by changing over column selection lines while changing over an address signal to be inputted to a column decoder every cycle at the time of writing and reading operations in the case of a test mode. SOLUTION: In a normal time, a burst counter 3 latches external addresses by writing and reading commands to perform a coating operation. In this case, internal address signals YP2-YPN of a column decoder 4 are not changed and consequently a column selection line YSW is not changed over also. When a test signal becomes 'HIGH', internal address signals YP0, 1 preserve preceding data and signals YP2-YPN perform counting operations. Moreover, N type transistors 31, 32 become conductive states and the lower rank side two bits of the burst counter 3 are inputted to the column decoder 4 as the upper part side two bits of the internal address signals YPN-1, N. Consequently, the column selection line YSW is changed over every one cycle. Thus, efficiency is enhanced by shortening a test time by the parallel test of plural cells.
