Title: Associative storage device system and programmable read-only memory
Inventor: JIEEMUZU YUU
IPC: G11C5/14
Filed: 1994-06-01
Abstract: PURPOSE: To correctly operate an associative memory device in both of reading- out and program modes by changing over the first and second bias voltages applied to this device by a selector switch according to the detection results of the first and second source voltages supplied to the device. CONSTITUTION: The respective detecting circuits 48 or 50 and 60 output signals 49, 52, 62 when these circuits detect the source voltages Vcc or Vpp , in both reading-out and programming modes of the EPROM of the associative memory device. The sure and adequate operation of both modes is executed by a latch 14 and the spare columns and rows 30 and 32 of a ROM 18 are exactly addressed by the reset signal 42 outputted from an OR gate 64 by these signals. The switch 58 selects the adequate bias voltage 54 or 56 for both modes to be inputted and outputs the voltages to a UPROM 12 by the signal 52. As a result, the ROM 18 is programmed by the low source voltage, by which power source consumption is reduced. The ROM is operated by the high voltage during the programming. The correct operation is thus executed at multiple power source levels.

Title: Semiconductor power converter
Inventor: SUMI HIROE
IPC: H02M7/48
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To minimize the waveform distortion of the whole of the drive of a three-level inverter circuit, by reading from a time-data table a variable concerning the outputting time of its state at a modulation factor, and by generating gate pulse signals based on the data obtained through setting the value of the variable to a waveform-data table. SOLUTION: After inputting to a microprocessor 43 a driving-frequency command 45 of a three-level inverter circuit, it is A/D-converted by an A/D converter 46. Then the A/D-converted command is converted into a modulation- factor voltage command 48 by the V/f converting function of a V/f converter 47. Then, based on the driving-frequency command 45 and the modulation-factor voltage command 48, a state output time data table 49 for outputting the outputting-time of one control-period portion and the state is read. The data read from the data table 49 are inputted to a pulse converter 50 to output the data as gate pulse signals 44 from the converter 50 to a gate driving circuit 42. As a result, the waveform distortion of the whole drive of the three-level inverter circuit can be minimized.

Abstract: PURPOSE:To make it possible to prevent the inadvertent forgetting of capping to a recording liquid discharge port, by providing a control circuit for closing the recording liquid discharge port of a recording head by a cap apparatus prior to performing the cutting-OFF of a power source circuit. CONSTITUTION:When a main switch 21 is turned OFF, a one-shot multiplier 25 resets CPU26 but, because a cap sensor switch 24 is set to a 24'-side, AND29 comes to L and an inverter 30 is brought to H to turn a transistor Tr1 ON while a power source circuit 23 is held under an ON-state because a sub-switch 22 is closed. In the next step, a carriage is returned to the home position by the signal from a driver circuit 27 and, when this operation is detected, an ink discharge port is covered with a cap by the order of CPU26. Whereupon, the cap sensor switch 24 is set to a 24''-side and the output of AND 29 is brought to H to turn the power source circuit 23 OFF. By this method, the solidification and clogging of ink at the recording liquid discharge port can be prevented.

IPC: G03B33/00
Filed: 1981-08-01
Abstract: PURPOSE:To obtain luminance distributions which are good for practicability over a relatively wide visual field range and to obviate the generation of color shafts and color shading by selecting the shape of the lens faces of lenticular lens with respect to a transmission type screen. CONSTITUTION:The sectional shape of semicircular lenses is selected to the curve between the threshold curves Z1 and Z2 expressed by specific formulae. The screen gain for the curve Z1 and the screen gain for the curve Z2 has relatively large luminances both in the range of 0-+ or -40 deg. directional angles. If the sectional shape is selected to the curve between said curves, the good luminance distributions are obtained.
