Title: Buffer memory control system
Inventor: INUI YOSHIO
IPC: G06F13/00
Filed: 1978-03-03
Abstract: PURPOSE: To improve the use efficiency of a buffer memory by stopping immediately the transmission/receiving processing of a data block where a fault occurrs and making it possible to restart the transmission/receiving processing of the next data block.  
     CONSTITUTION: In case that line control part 202 detects anomaly occurrence in the receiving operation, the receiving operation of the block is stopped to restart to store the next data block from the next address. Meanwhile, in case that control part 202 detects anomaly occurrence in the transmission operation, executing address 303 is corrected to set the start address of the data block if one data block write completion indication 304 is set by interface control part 200; and executing addresses 302 and 303 are caused to agree with each other forcedly to set this address as the start address of the data block if the final address has not been set yet. As a result, the needless processing at an anomaly occurrence time is eliminated to be able to improve the use efficiency of the buffer memory.

Title: Method and device for detecting ductal disturbance by ultrasound
Inventor: TAKEUCHI YASUTO
IPC: A61B8/06
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To prevent influence of acoustic waves with no relation by applying ultrasonic acoustic waves to an internal duct of an object, receiving I code, and detecting an obstacle in the duct from a Doppler signal of an echo. SOLUTION: An operator applies an ultrasonic probe 2 to a desired region of a tested body 4 to perform ultrasonic photographing. That is, a Doppler signal observation point and a sound ray passing the point are set on a B mode image by operation of an operating part 18, and then it is switched to a Doppler mode. Thus, transmission of a pulse ultrasonic wave is repeated, a Doppler processing part 8 processes an echo receive signal to obtain a Doppler signal. For example, in the case of a blood vessel wall of a carotid, a Doppler signal corresponding to the sound of a flowing blood stream is obtained. The Doppler signal directly comes into contact with the vibration of the blood vessel wall, so that it is independent of external acoustic waves. Accordingly, a bloodstream sound not influenced by external acoustic waves or the like can be obtained.

Title: High frequency switch circuit
Inventor: KANDA ATSUSHI
IPC: H03K17/693
Filed: 1994-02-23
Abstract: PURPOSE:To provide the high frequency switch circuit in which a passing loss in the on-state is small and leakage of a signal in the off-state is less. CONSTITUTION:When an antenna and a reception circuit are connected, a forward bias is applied to a FET 9 to set its drain-source impedance to be properly low and the impedance is equivalent to its on-resistance, but the impedance is converted into a high impedance by a 1/4 wavelength line 112 and then the impedance of the FET 9 when viewing it from a node 13 is close to an open impedance. On the other hand, a reverse bias is applied to a FET 8, the drain- source impedance by its junction capacitance is properly high, but the impedance is converted into a low impedance by a 1/4 wavelength line 111, and the impedance of a node 12 is sufficiently close to a short-circuit state. Then the impedance is converted into a high impedance by a 1/4 wavelength line 6. Thus, a high frequency signal received by an antenna connection terminal 1 is not leaked to a transmission circuit connection terminal 2 but outputted to a reception circuit connection terminal 3.

Title: Optical connector
Inventor: ISHIDA HIDETOSHI
IPC: G02B6/36
Filed: 1988-02-05
Abstract: PURPOSE:To improve the breakage strength of the optical connector by specifying the radius of curvature of the minimum-curvature part of V-groove bottom parts where guide pins and optical fibers are positioned and fixed. CONSTITUTION:The bottom pars of the V grooves 3 and 4 where the guide pins and optical fibers are positioned are machined having a >=30mum radius of curvature even at the minimum-curvature part. Namely, the bottom part of the V groove 10 with a 60 deg. opening angle is rounded and the groove is grounded with a V blade whose tip is rounded to easily obtained the groove. Consequently, if bending stress after the attachment or detachment of the connector or the coupling of the connector at the time of pin insertion causes the V groove to be stressed, the stress is prevented from being converged on the V-groove bottom part and the breakage strength of the optical connector can be improved.
