Title: Imaging method and device
Inventor: WADA TOMOYUKI
IPC: H01S3/30
Filed: 1995-04-06
Abstract: PURPOSE: To utilize a laser which emits laser pulses whose width is of the order of nanoseconds by a method wherein a coherent image signal component contained in a probe light and a coherent excitation state induced in a Raman medium are made to interact with each other, and only the coherent image signal component is Raman-converted into an anti-Stokes light. CONSTITUTION: Pulse laser beams of a YAG laser 10 are split into two polarized components by a polarizing spectroscope 14, one of the polarized components is made to irradiate a specimen 20 through the intermediary of total reflection mirrors 16 and 18, and the other component is made to impinge on a Raman cell 26 of Raman medium to put the Raman medium in a coherently stimulated state. A probe light which contains the coherent image signal component and the scattered light component of the specimen passing through it is made to impinge on the Raman cell in a coherently stimulated state. The coherent image signal component and the coherently stimulated state are made to interact with each other to Raman-convert only the coherent image signal component into an anti-Stokes light through a filter 28.

Title: Ultrasonic diagnostic device
Inventor: ISHIMURA TOSHIAKI
IPC: G01N29/22
Filed: 1989-04-27
Abstract: PURPOSE:To always suitably display an ultrasonic image even when the number of ultrasonic scanning lines is changed by erasing the stored contents of a storing means when the number of the ultrasonic scanning lines is reduced at least. CONSTITUTION:When an input signal is Low, a freeze control circuit 7 prohibits the reloading of a frame memory in a DSC 4 and when the input signal is High, the freeze is canceled. When the freeze is canceled, the freeze control circuit 7 once clears (erases) the memory in the DSC 4 and afterwards, it is started to reload the memory. When a scanning line changeover switch 8 is turned ON or OFF, namely, when the number of the ultrasonic scanning lines is switched, a freeze signal generating circuit 10 outputs a signal, which is made Low for a fixed period, through an OR circuit 11 to the freeze control circuit 7. Thus, the freeze control circuit 7 freezes the DSC 4 for the fixed period and afterwards, the freeze is canceled. Then, the contents of the memory in the DSC 4 are once cleared.

Filed: 1987-05-01
Abstract: PURPOSE:To prevent occurrence of reading errors by forming an opaque masking mark which can be mechanically removed on a mound showing a sense mark so that this sense mark is covered by the masking mark. CONSTITUTION:A sense mark 13a is formed on a mount 11 and covered with an opaque masking mark 13b. This mark 13b can be easily removed by a nail, a coin edge, a knife, etc. When data are read, the mark 13b is removed and the mark 13a emerges. Thus the data reading errors can be avoided. Furthermore the positions of a light emitting element LE and a light receiving element LS of a reader are selected so that the incident angle theta of the light to the mark sheet paper is set in such a direction where the reflection factors are set close to each other between the mark 13b and the mount 11. As a result, it is possible to extremely decrease such errors where the reader misreads the mark 13b.
