Title: Inverter circuit for fluorescent lamp
Inventor: MORI IICHIRO
IPC: H05B41/282
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To provide the inverter circuit for a fluorescent lamp, which is compact, and low in noise by turning a switching transistor on when terminal voltage at the output side is high, and however, turning the switching transistor off when terminal voltage at the output side is low. SOLUTION: Voltage at the output terminal of an inductance is compared with a reference voltage by a control circuit 3. And a transistor is driven in such a way that a switching transistor is turned off when terminal voltage at the output side is high, and the switching transistor is turned on when terminal voltage at the output side is low. By this constitution, a main switching transistor is synchronized with the oscillation frequency of a resonance type Royal inverter circuit, and furthermore, since the output side voltage of an inductance corresponding to input voltage is compared with a reference voltage so as to be controlled, two switching circuits can be synchronously operated by letting one circuit be so constituted that one smoothing coil can be commonly used by two switching circuits.

Abstract: PURPOSE:To obtain a high quality semiconductor device in utilization of a high concentration impurity effect of a substrate by removing the periodic distribution of the specific resistance of an active layer and by preventing the effect of oxygen contained in the epitaxial substrate. CONSTITUTION:A CZ, N type Si substrate 11 having a specific resistance of 8- 12OMEGAcm is heat treated for 4hr in the atmosphere of argon at 1,100 deg.C so as to diffuse the oxygen contained in the substrate outwards. The substrate is then subjected to heat treatment for 16hr at 700 deg.C in the atmosphere of oxygen so as to form nuclei for generating precipitates in a bulk. The substrate is further heat treated for 6hr at 1,000 deg.C in the atmosphere of oxygen to grow the precipitates. On the substrate 11, a region 12 free of defects, a region 13 with defects of high density, an N type high concentration impurity layer 14 and an N type epitaxial layer 15 are formed. In such a manner, the periodic distribution of the specific resistance of the active layer is removed and the effect of oxygen contained in the epitaxial substrate is prevented, so that a high quality semiconductor device can be produced.

Title: Display device driving method
Inventor: YAGYU MINETO
IPC: G02F1/133
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To satisfactorily display the halftone based on analog data. SOLUTION: An optical modulation element in which the layer of an optical modulation material is arranged between paired electrodes and a photoconductive layer are applied with an analog multilevel signal and a readout light is lighted. The readout light is subjected to a duty-modulation by adjusting a timing when the voltage to be impressed on the optical modulation material exceeds a threshold value and a lighting time. At this time, pixels having optical modulation materials added with driving elements are arranged in a matrix. a signal having voltage values corresponding to multilevel information is time sequentially supplied to source lines S1 -SM and a signal of turning successively switches TFTs ON is supplied to gate lines G1 -GM and these lines are scanned in a multiplexing mode and also the readout light is scanned.  Thus, since a time when the readout light is can be recognized is modulated, the readout light can be subjected to analog modulation even by using digital elements.

IPC: G01N30/86
Filed: 1989-07-31
Abstract: PURPOSE:To automatically judge the timing for starting an analysis operation by emitting an analysis start signal when the fluctuation width of a base line falls to a decision level or below. CONSTITUTION:The base line detection time (t) and the base line decision level level A are inputted from a constant setting section.

Abstract: PURPOSE:To reduce the load of a software at the time of the rewrite of data by providing a means to write the data from an external part in a non-volatile memory element, impossible to be rewritten electrically. CONSTITUTION:An EEPROM 1 is provided with a memory cell array 11, an address decoder 13, a column latch 14 and a sequence control circuit 15.

Afterward, it erases the data of the prescribed address in the designated array 11 by impressing a prescribed voltage to each node of a memory cell, and writes the contents of the latch 14 in the address. Thus, a CPU 3 need not participate in data transfer from the RAM to the EEPROM 1 and the rewrite operation of the EEPROM 1, and the load of the software can be reduced.
