A hole part 3 opening downward is formed in the reduced diameter lower part. A shallow depression 4 is formed on the upper face of the expanded diameter upper part 1, and a ring type protrusion 5 touching in a line to an inside periphery face 11 of a blood collecting needle adapter 10 is expanded out and formed. On the hole part 3 of the reduced diameter part 2, a small bore hole part 7 is formed opening downward from the bottom part 6 toward the expanded diameter part, and the diameter of the small bore hole part 7 is formed with a larger diameter than the outside diameter of the blood collecting needle 12 not to touch the blood collection needle.  Therefore, the wall thickness D of the part from the shallow depression part 4 to the bottom of the small bore hole part 7 is formed extremely thin.

Title: System and method of exchanging bucket
Inventor: MIKIERU ROIYARU RARUSON
IPC: H04L12/22
Filed: 1989-09-20
Abstract: PURPOSE: To attain valid ciphering by simple constitution by separating a packet and ciphering only a flag at the time of packet transmission in a packet exchange system. CONSTITUTION: At the time of transmitting a packet on a connected trunk, a packet is separated and only a flag is ciphered. Namely the flag pattern of a packet to be transmitted to a trunk controller 140 is ciphered by a trunk controller 131 through a trunk 118. Since a flag for determining the start and end of a packet to be transmitted on a link such as a high speed data transmission trunk is ciphered, data ciphering can be validated by simple constitution.

Title: Clock reproduction phase locked loop circuit
Inventor: EJIMA NAOKI
IPC: H03L7/08
Filed: 1986-10-13
Abstract: PURPOSE:To shorten pull-in time by providing a circuit generating a pulse with T/2 (T: minimum inversion frequency), a voltage controlled oscillator circuit and an analog gate circuit which supplies signals outputted from a phase comparator circuit to a low-pass filter only during a period for a T/2 pulse activated by the edge of an input signal. CONSTITUTION:The titled circuit is provided with a T/2 pulse generation circuit 2 which is activated by the edge of the input signal and generates a pulse with T/2, the voltage controlled oscillator circuit 6, the phase comparator circuit 3, the low-pass filter 5 and the analog gate circuit 4 which supplies the signal outputted from the phase comparator circuit to the low-pass filter during the period for the T/2 pulse activated by the edge of the input signal. The analog gate circuit 4 supplies phase error information to the LPF 5 while said information is found: otherwise, it converts an output from the phase comparator circuit 3 into a high impedance. The circuit 4 forms a sample/hold circuit together with the LPF circuit 5 at a subsequent stage, whereby a section without the phase error information can be interpolated with information just before the former information. Thus the pull-in time can be shortened.

Title: Data transmission system
Inventor: YOSHIDA AKIO
IPC: H04L12/40
Filed: 1988-09-27
Abstract: PURPOSE:To prevent the traffic of a network from increasing uselessly and to maintain the performance of the network at the time of causing high traffic by suppressing a data transmission when the re-transmission is expected. CONSTITUTION:When acknowledgment A indicating reception failure is received, a node B which has received the data A before re-transmitting data A, where transmits new data B or not is supervised for a time specified beforehand, when the transmission of the data B is detected in the time, the re-transmission of the data A is awaited until the detection of acknowledgment B for the data B. Consequently, when the acknowledgment B is not detected, the resending of the data A is directly executed by a time-out, and the re-transmission of the data A, for which the transmission of the acknowledgment A to indicated the reception failure from the node B is expected, is controlled. Thus, the traffic of the network can be prevented from being increased.
