Title: Ultrasonic diagnostic apparatus
Inventor: KUMAZAWA KOJI
IPC: G01N29/22
Filed: 1989-11-20
Abstract: PURPOSE:To subject an echo signal to filtering processing in the optimum S/N ratio without receiving the effect of stray capacitance by mounting a frequency converting means changing conversion center frequency to a low frequency side to subject the echo signal to frequency conversion and a high-pass removing filter means. CONSTITUTION:The echo signal subjected to phasing addition by a delay addition part 4 to be outputted is applied to a frequency converting part 5 along with a reference signal controlled so that conversion center frequency changes to low frequency on the basis of fo (center frequency) data to be converted to low frequency. Continuously, the echo signal converted to low frequency is applied to a high-pass removing filter 8 set to such a characteristic that cut-off frequency changes on the basis of fc (cut-off frequency) data to be subjected to filtering processing and a high-pass component is cut. Next, filter output is applied to a detection part 9 and a low frequency component is taken out to obtain diagnostic data.

Title: Recording device
Inventor: FUKUSHIMA HISASHI
IPC: B41J2/485
Filed: 1989-11-20
Abstract: PURPOSE:To prevent a recording area from becoming crowded out of a recording sheet or an image blank space from becoming large even if the recording sheet stretches or shrinks due to an environmental condition by providing a multiplying factor adjustment device which fine-adjusts a record multiplying factor in accordance with the ambient condition of a recording sheet. CONSTITUTION:The degree of stretching/shrinking of paper is calculated using a center control part 10 based on ambient temperature and humidity detected by a temperature/humidity sensor 420 in a varying multiplying factor control part 11. Then an image is recorded on a recording sheet by increasing a varying multiplying factor by a stretched amount or decreasing said factor by a shrunk amount in accordance with the calculation results. That is, the varying multiplying control part 11 is activated with a reading part 12 having a zoom optics, and thereby varying multiplication process is performed by adjusting a multiplying factor when an image on a copy is read. Thus variably multiplied image data which is thus read is processed by means of specified program in an image processing part 13 and a recording head of a recording part 302 is driven based on the variably multiplied image data subjected to image processing.

IPC: H01L29/788
Filed: 1990-11-06
Abstract: PURPOSE:To make a cell area small by a method wherein a control gate is divided into two parts, one of them is coupled to a floating gate at a prescribed thin oxide film and is used as a control gate exclusively for write/erasure operation use and the other is coupled to the floating gate at a prescribed comparatively thick oxide film and is used as a control gate exclusively for readout operation use. CONSTITUTION:A control gate is divided into two parts. One of them is coupled to a floating gate at an oxide film 4b which is nearly as thin as a tunneling oxide film 4b1; and it is used as a control gate 3c exclusively for write/erasure use. The other control gate 3d is coupled to the floating gate 5 at a comparatively thick oxide film 4a which is nearly as thick as a gate oxide film 4a for an NMOS transistor; and it is used as the control gate 3d exclusively for readout use. Since a voltage is applied through the thin oxide film 4b2 at a write/ erasure operation, the area of the control gate can be made small. At a readout operation, the control gate 3d coupled to the thick oxide film 4a is used, and the control gate 3c coupled to the thin oxide film 4b, is floated electrically. Thereby, it is possible to prevent a charge holding characteristic from being deteriorated.
