Title: Reading method of radiation image
Inventor: SUZUKI TOSHIAKI
IPC: A61B6/00
Filed: 1982-08-19
Abstract: PURPOSE:To keep the planeness of a sheet to read an image with a high precision, by raising a suction pressure at the start time of sheet carrying and lowering the suction pressure at the time when it is confirmed that the sheet is carried for a prescribed distance. CONSTITUTION:When the front end of a storage-type phosphor sheet 10 comes to a position a little before a prescribed position where a laser light 205 scans, air suction with a sufficiently high negative pressure is started in a suction box 203a, and the sheet 10 is brought closely into contact with a perforated belt 201. When it is detected by a detector 214 that the front end of the sheet 10 is irradiated with the laser light 205, the negative pressure of the box 203a is lowered to prevent the vibration of the sheet 10 due to an air sucking blower. When the upper part of a box 203b is covered completely with the sheet 10, suction of the sheet 10 is started, and the sheet 10 brought closely into contact with the belt 201 is carried in a uniform velocity with a high precision while keeping its planeness. Consequently, the image is read with a high precision without the variance of reading because of the planeness of the sheet and carrying under the uniform velocity.

IPC: H04N3/22
Filed: 1977-12-01
Abstract: PURPOSE:To reduce the thermal loss of a constant-voltage circuit and to prevent the size of a screen from varying by enabling the power voltage of a horizontal deflecting circuit and that of an accelerating high-tension circuit to vary, securing fixed  relations, with a received voltage. CONSTITUTION:Horizontal-deflecting power-supply control circuit 8 and accelerating high-tension power-supply control circuit 9 stabilize and apply a voltage from DC power supply to horizontal deflecting output circuit 1 and accelerating high- tension output circuit 3 respectively. According to the voltage variation of power supply 5, circuits 8 and 9 vary a constant output voltage determined by resistances R1 and R2, and R3 and R4. In general, since the relation among variation DELTAW in light-spot deviation, variation DELTAI in deflecting current and variation DELTAV in accelerating voltage is represented by DELTAW/WsimilarDELTAI/I-DELTAV/2V, the size of a screen can be stabilized by making the variation rate of the output voltage of circuit 9 twice as high as that of circuit 3.

Abstract: PURPOSE:To improve the accuracy of A/D conversion in an one-chip microcomputer having an A/D conversion function by switching to an external A/D conversion circuit when the operation voltage and A/D conversion accuracy of the microcomputer are low. CONSTITUTION:When a request judging means 10 is driven in each operation period of A/D conversion in a processor 1, a request instruction is judged and selecting operation is executed. Namely when high accuracy is instructed, and exclusive A/D conversion circuit driving means 12 is started, and when normal accuracy is instructed, an A/D conversion part driving means 11 is started. When the means 12 is started, an external exclusive A/D conversion circuit 3 is driven through a signal line 4. When the means 11 is started, an internal A/D conversion part 2 is driven and the A/D conversion part 2 executes the A/D conversion of an inputted analog signal. Thus only one of the A/D conversion part 2 and the A/D conversion circuit 3 is driven and the other which is not driven is maintained at a stopped state without executing its A/D conversion operation.
