Patent JP-H04359680-A (JP)
Title: Shifted magnetization controller
Inventor: TAKAHASHI TSUYOSHI
IPC: H02M7/537
Filed: 1991-06-07
Abstract: PURPOSE:To suppress DC component in AC output voltage by subjecting DC component detection signal of AC output voltage from an AC converter to operational conversion, distributing signals to the phases corresponding to the phases containing DC component, and then adding thus distributed signal to a voltage control signal. CONSTITUTION:When an AC output voltage contains DC component, voltages or currents of DC component detectors 5-7, each comprising a reactor having an integrator or a magnetic circuit and the like, increase. Outputs from the detectors 5-7 are applied to signal distributors 8-10, each comprising a primary delay circuit, a filter, a polarity converting circuit, and the like. The signal distributors 8-10 convert thus received outputs into signals having such polarity as canceling the DC component of the AC output voltage. Outputs from the signal distributors 8-10 are added to a signal from a power control circuit 15 through adders 11-13. Output signals from the adders 11-13 control the positive and negative side areas to be equal each other. Upon receiving the signal, an ON time control circuit 16 controls ON, OFF intervals of a switching element. Consequently, the AC voltage is controlled to have same areas on positive and negative sides.

Title: Peak value follow up circuit
Inventor: IIZUKA IKUO
IPC: H03M1/12
Filed: 1986-06-12
Abstract: PURPOSE:To prevent holding performance from being lowered, by latching a peak value, and controlling the peak value so as to be held during a period until to the next peak point. CONSTITUTION:As for the code bit of an A/D converter 1, by passing a signal delayed by the cycle of a clock T1 at a latch 6, and the signal inverted at an inverter 4, through a NOR gate 7, a pulse equivalent to the cycle of the clock T1 is generated only at the time of changing the code of an input signal from a positive to a negative, and a clock T2 is added on a latch 9 through an AND gate 8, and the peak value of the input signal at a time t5 is written. Simultaneously, a latch 2 is reset. The code bit is inputted to an AND gate 5 through the inverter 4, and no change occurs in the latch 2 for peak detection in the negative period of the input signal. The latch 2 performs the tracking of the maximum value from a time t1a, and holds the value at a time t16 when the input signal starts to drop, and transfers the held value to the latch 9 at a time t17 when the code of the input signal changes from the positive to the negative, and resets the latch 2 simultaneously. Thus, by repeating such operation, the output of the latch 9 in which a positive peak value by every cycle is followed up, can be obtained.

IPC: G11C11/34
Filed: 1984-07-04
Abstract: PURPOSE:To solve completely a decrease in action margin of a memory cell caused by processing dispersion even if a device is made fine by constituting a capacity of a memory cell by putting together with two capacities approximately in the same shape as that for constituting substantially a capacity of a dummy cell. CONSTITUTION:In terms of a memory cell 7, an area for forming a capacity is divided into two areas 17A and 17B. The separation of two areas 17A and 17B is executed by providing a thick oxide film (field oxide film) on a part 14 held by two areas. The areas 17A and 17B are approximately equal to an area 24 for forming a capacity of a dummy cell in a structure and shape. As a result, even if the processing dispersion arises, it is equal in the areas 24, 17A and 17B, and therefore the capacity can be secured by capacity ratio 1:2 of a dummy cell capacity CDC and memory cell CMC.

Title: Semiconductor light detecting element
Inventor: FUJII YOSHIMAROU
IPC: H01L31/02
Filed: 1993-06-08
Abstract: PURPOSE:To provide a semiconductor light detecting element which can detect the light in wavelength range from an ultraviolet ray to an infrared ray, suppressing the difference of sensitiveness in detection depending upon the position of an incident light. CONSTITUTION:A light, which has entered from a light receiving area and reached a high-resistance layer 110, is absorbed in this region, and it generates a signal charge geared to the intensity of an incident light. The signal charge shifts according to the electric field occurring in a photodiode, and reaches an electrode 150 or an electrode 160. In this detecting operation, the average depth of penetration of an infrared ray out of incoming lights is large, and the possibility of the sum of the absorption depth and the diffusion length of generated charge reaching the vicinity of the rear is high, but a low-resistance layer 120 is formed thicker than the region where crystal defects exist of the substrate, and there is substantially no crystal defect on the rear of the high- resistance layer 110, and the thickness of the high-resistance layer 110 and the surface condition on the rear side are nearly equalized to the position of incidence, so the occurrence of the difference of sensitiveness in detection depending upon the position of incidence is suppressed.
