Title: Ultrasonic diagnosing apparatus
Inventor: KOBAYASHI KOICHI
IPC: G01N29/06
Filed: 1990-04-19
Abstract: PURPOSE:To enable the observing of an ECG waveform accurately at a B mode display time phase by processing an optional time phase with respect to that other than an optional time phase of an electrocardiographic signal to be displayed in a visually different manner simultaneously with a display of an ultrasonic image of an optional time phase synchronizing heart beats based on electrocardiographic signals of time phases read out of first and second memories, a time phase signal of an optional phase and an ultrasonic image. CONSTITUTION:An ultrasonic image is written into an ultrasonic image memory 5C and when the ultrasonic image is read to be displayed on a TV monitor 6, based on ECG signals of time phases read from planes P1 and P2 of an ECG memory 13 and a refresh timing signal of a time phase indicated by a B mode image, a time phase indicated by the B mode image with respect to a time phase other than that indicated by the B mode of the ECG signal is processed to be displayed in a visually dark manner (gray level). Thus, a freeze image synchronizing heart beats with a time phase indicated by the B mode image can be displayed while ECG signals of all time phases can be observed accurately without blanking of an ECG waveform as caused by the time phase indicated by the B mode image. Moreover, this facilitates the recognition that a time phase (gray level) indicated different visually is a time phase indicated by the B mode image.

Abstract: PROBLEM TO BE SOLVED: To obtain a radiation image reader capable of rapidly performing image reading processing by providing a system for carrying a stimulable phosphor from its entrance to any of plural image reading parts. SOLUTION: When a user instructs the read-out of an image on a stimulable phosphor 21a in a cassette 22a, for example, through a console 81 provided at the upper part of a main body 1a, a control part 100 controls a roller driving means 103 so that the phosphor 21a may be pulled out to the outside of the cassette 22a and delivered to an entrance side carrying system 30A by a roller 40. The pulled out phosphor 21a is fed to 1st and 2nd image readers 70a and 70b by a collective carrying system 50. Since the phosphor 21a on which the image is recorder is carried to any of plural image reading parts by the carrying system, the images are simultaneously read in the image reading parts, whereby image reading is more efficiently performed.

Title: Casting nozzle for continuous casting machine
Inventor: BUIRUHERUMU FURIIDORITSUHI RAU
IPC: B22D11/06
Filed: 1987-04-30
Abstract: In a casting nozzle, tubes are placed between a bar-shaped mouthpiece and a distribution bar, which connect holes in the mouthpiece and the distribution bar to allow for the flow of the melt. Pulling rods which are under tension, are anchored to the mouthpiece and to the distribution bar and press these parts elastically against the ends of the tubes in such a manner that the nozzle components are elastically braced, yet remain flexible and can adjust freely to heat dilatations or inaccuracies which occur in fabrication or assembly. The nozzle components, particularly the tubes, are easy to obtain and to exchange. Due to the fact that the pulling rods enter the mouthpiece from its back side and are anchored therein, the mouthpiece can be very slender, thus allowing for thin casting.

Title: Digital communication system
Inventor: IKEGAMI FUMIO
IPC: H04L1/02
Filed: 1985-05-15
Abstract: PURPOSE:To improve a code error rate in case of propagating a multiple wave by setting effectively a signal level of the latter half of each time slot to zero. CONSTITUTION:A binary phase shift keying (BPSK) - RZ signal is obtained by multiplication of a usual BPSK signal and an on-off signal which is '1' only in an optional T/2 section of each time slot. This signal has the same amplitude and phase as those of the usual BPSK signal in a section of T/2 of the first half of each time slot, and its carrier wave amplitude becomes zero effectively in the remaining T/2 section. When a multiple wave of this BPSK - RZ signal is regenerated by a delay demodulator, an effective output is always obtained irrespective of a phase difference of a wave D and a wave U, in section (a), (c), and section (b), (d), in case of 2/T<0,5, and 1>n/T>0.5, respectively. Therefore, such a problem as an eye of an eyepattern annihilates or a horizontal fluctuation becomes large is eliminated.
