Title: Method for reading radiation picture
Inventor: HORIKAWA KAZUO
IPC: H04N1/113
Filed: 1988-08-09
Abstract: PURPOSE:To improve processing ability per unit time by respectively converting light within respective light quantity ranges obtained by dividing the entire light quantity range of the light which expresses a radiation picture into plural stepwise into a signal within the input signal range of a logarithmic amplifier which is excellent in responsiveness and reading it. CONSTITUTION:A gain setting means 22 is successively controlled every light quantity range so that the light within the respective light quantity ranges obtained by dividing the entire light quantity range of the light which expresses the radiation picture into plural stepwise may be respectively converted into the signal within the input signal range of the logarithmic amplifier 26 which is excellent in responsiveness and reading is performed. As a result, logarithmic conversion is performed with complete accuracy even if a reading speed is increased.

Title: Effective sound generating device
Inventor: KONDO KIMIO
IPC: A63F7/02
Filed: 1990-07-25
Abstract: PURPOSE:To reduce the necessary storage capacity of effective sound data by storing continuous codes equal to a unit sound data length instead of effective sound data following the initial effective sound data when the same effective sound is continued. CONSTITUTION:A sound data output means 2 successively reads out effective sound data stored in a storage means 19 in each unit sound data and outputs the read data to a sound generating means 15, which continuously generates an effective sound corresponding to the effective sound data until the input of the succeeding effective sound data. When the same effective sound is continued, continuous codes equal to the unit sound data length are stored in the means 19 instead of the effective sound data following the initial effective sound data corresponding to the same effective sound. When the data read out from the means 19 are continuous codes, the means 2 inhibits the output of the data. Since an effective sound corresponding to the effective sound data inputted in the preceding time is continuously generated from the means 15, the necessary storage capacity of effective sound data to be stored in the storage means 19 can be reduced.
