Title: Ultrasonography and apparatus
Inventor: TAKEUCHI YASUTO
IPC: G01S15/89
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To accomplish a reflexographic image without a range gate by scanning a specified section of a specimen to generate a C-mode image based on a high frequency component of a received echo. SOLUTION: An ultrasonic beam 20 to be transmitted from an ultrasonic probe 10 is converged onto a focus F on a section 22 to generate a high frequency in an area Z. An echo for the transmitted ultrasonic wave is returned to the ultrasonic probe 10 to be received. The resulting echo signal is sent to a signal processing section 30 through a T/R switch 18 to be controlled by a gain function generator 36 and the gain thereof is amplified by a variable gain amplifier 34 thereby accomplishing an attenuation correction of the echo corresponding to depth at a reflection point. The resulting output is inputted into a scanning converter 46 through a band pass filter 38, an envelope detector 40, an integrator 42 and a holder 44. The results are shown on a display device 48 as one pixel of image data of a C-mode image under the control of a controller 28.

Filed: 1985-08-06
Abstract: PURPOSE:To discriminate an input signal unstable in a logical state and an input signal stable in a logical state, by discriminating both signals by using two threshold values different in a level. CONSTITUTION:High threshold value and low threshold value signals 31, 32 corresponding to the logical operation levels of TTL level and ECL level elements indicated by a level indication switch 2 are outputted from a threshold valve generation circuit 3. For example, if a TTL level is indicated, a voltage valve of +2.8V is set to the signal 31 and a voltage value of +0.5V to the signal 32 and both voltage values are guided to two comparators in a probe 4 to be compared with and discriminated from an input signal 10. In the high level comparator, the level higher than the threshold value of +2.8V is judged as a logical value 1 and the level lower than said threshold value is judged as a logical value 0. In the low level comparator, the level higher than the threshold value of +0.5V is judged as a logical value 1 and the level lower than said threshold value as a logical value 0. These judge results are transmitted to both high and low discrimination result memories 6, 7 and stored therein in synchronous relation to the clock value indicated by a clock signal 50. Subsequently, the logical values read from the memories 6, 7 are guided to a display device 9 to discriminate unstable and stable signals.

Title: Cassette tape recorder
Inventor: NAKAMORI HIROSHI
IPC: G11B33/02
Filed: 1989-07-06
Abstract: PURPOSE:To make an internal vibration hard to transmit to the outside and to eliminate an effect upon an internal mechanism due to an external shock by fitting a mechanism substrate to a cabinet with a screw capable of penetrating only an elastic body provided on an inner wall of the cabinet. CONSTITUTION:A vibration from an internal vibration source (mechanism) is suppressed by the elastic bodies 23b and 24b provided on the inner wall of the cabinet and then transmitted to the cabinet. Then, even when force (impact) is received due to external force, this external force is absorbed by the elastic bodies 23b and 24b provided on the inner wall surface of the cabinet. Consequently, deformation of the mechanism substrate 21 is prevented, and hence the strength of the whole machine can be promoted. Then, moving things such as a cassette lid body and a knob, etc., and fixing things such as the screws, etc., are fitted by utilizing the elasticity of the elastic bodies provided on the inner wall of the cabinet, so that the airtightness of the inside of the device can be maintained. By this method, the transmission of the inner vibration to the outside and the transmission of the external force to the inside can be suppressed to minimums.
