Mobile X-ray device

A power supply controller is used in a device including at least one component and at least one control board for controlling an operation of each component, and includes: a power supply section; and a power supply board for independently supplying a power supply voltage output from the power supply section to each of the component and the control board. The power supply board includes an output control circuit for independently controlling to output or to stop outputting the power supply voltage supplied from the power supply board to each of the components based on a signal indicating one of a normal state and an abnormal state of the power supply voltage used in each control board, which is fed back to the power supply board from each control board when the power supply voltage is supplied from the power supply board to each control board.

Power supply controller

An optical printer has a DMD as a spatial light modulator. An optical image corresponding to a fraction of a picture frame is projected from the DMD onto a photographic paper at a predetermined time interval. The photographic paper is advanced intermittently by a length corresponding to an exposure area for one optical image. A fluctuation value from a set advanced length for one advancing step is detected at each advancing step and accumulated. The DMD is mounted on a swinging plate whose angle is controllable by a piezoelectric element, to shift the exposure position on the photographic paper. In accordance with an accumulated fluctuation value, drive voltage to the piezoelectric element is changed from a reference value to correct the exposure position so as to print the picture frame without any gap or overlap between the fractions.

Optical printer with micromirror device

A MOS-type solid-state imaging device is disclosed capable of high speed scanning. The imaging device includes a plurality of photodiodes arranged in a matrix form, a vertical scanning circuit, a horizontal scanning circuit, a first group of switching transistors and a second switching transistors. The imaging device enables multiple pixel signals to be simultaneously outputted without adversely effecting adjacent pixel signals during a scanning operations. A separating layer formed of an impurity layer held at a predetermined potential is embedded at least between two adjacent switching transistors, thereby separating the capacitive coupling between the two adjacent sets of switching transistors.

Solid-state imaging device having a predetermined impurity layer

A solid-state imaging device constructed according to the TSL system having a plurality of photodiodes arrayed in matrix form so as to serve as a group of pixels, a vertical selection gate line extending from a vertical scanning circuit, a horizontal selection gate line extending from a horizontal scanning circuit, and a signal read line. A projection made of an impurity layer identical to that of the photodiodes is formed at an end of each of the photodiodes. A first switching transistor is formed by interconnecting the vertical selection gate line made of a polysilicon layer so as to cross over an upper surface of each of the projections. A second switching transistor is formed by laminating a gate portion made of a polysilicon layer on the other upper surface of each of the projections. Horizontal selection gate lines are formed by connecting between the vertically arrayed gate portions and an interconnection made of a conductor layer such as an aluminum layer insulatively laminated above the polysilicon layer. Signal read lines are formed by a conductive layer fabricated by a process identical to that of the conductive layer, and each signal read line is interconnected so that the upper surface of the projection and the upper surfaces of the first and second switching transistors are shielded thereby, and that the signal read line does not come in contact with the conductive layer forming the horizontal selection gate line.
