Title: Reception circuit
Inventor: KOBAYASHI HIDEAKI
IPC: H04L7/04
Filed: 2000-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain a reception circuit that does not reduce a setup/hold margin in a data fetch latch even in transmission of a small amplitude signal. SOLUTION: In a transmission system that simultaneously transmits/receives a data signal and a strobe signal to fetch the data signal, the phase difference between a variable delay output C1 of an internal reference clock signal C0 and a strobe signal STB is detected, and a variable delay amount of the reference clock signal C0 is controlled depending on the phase difference. A data signal is latched by the timing of the clock signal C1 subjected to delay control. That is, a phase difference signal S1 with respect to data fetch timing is generated according to the phase difference between the strobe signal and the reference clock signal to adjust the data fetch timing by using the signal S1.  Since a latch type circuit can be used in place of a level conversion circuit, jitters caused when applying level conversion to the strobe signal are not produced and data can be received with a very small jitter quantity which is independent of the amplitude of the input signal.

Title: Solid-state image pickup unit
Inventor: HAGIWARA YOSHIO
IPC: H04N5/374
Filed: 2000-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a solid-state image pickup unit that can provide a large pixel output with a wide dynamic range. SOLUTION: An optical current (electrical signal), generated by making light incident onto a photodiode PD, causes the gate voltage of MOS transistors(TRs) T1, T2 to increase and a current in response to this gate voltage flows through a MOS TR T2. When a voltage ϕ VPS applied to a source of the MO TR T1 is adjusted to activate the MOS TR T1 in a sub threshold region which is less than a threshold, the current flowing through the MOS TR T2 changes with the optical current natural logarithmically. The current flowing through the MOS TR T2 is changed linearly with respect the optical current, by setting the ϕ VPS applied to the source of the MOS TR T1 nearly equal to a DC voltage ϕ VPD.

Title: Method for immobilization and measurement of specific complex
Inventor: ISHIKAWA EIJI
IPC: C12M1/00
Filed: 2000-04-20
Abstract: PROBLEM TO BE SOLVED: To provide a method wherein, after a complex which contains a substance to be measured is formed in a reaction solution, the complex is bonded to an insoluble carrier with good efficiency so as to be measured and to provide a method wherein a complex which is formed once in a carrier is dissociated with good efficiency. SOLUTION: A substance which has an activity to form the complex specifically to the substance to be measured and to which a specific electrostatic group is introduced in advance is reacted with the substance, to be measured, in a solution to be inspected. The complex is formed in the solution. By an electrostatic action which uses an electric charge by the introduced electrostatic group, the complex is bonded to the insoluble carrier so as to be measured. In addition, the surface of a carrier in which a complex is formed via an electrostatic substance is brought into contact with a high-ionic-strength solution, and the complex is dissociated into the solution.  As compared with a capturing method or a dissociating method using an intermolecular action by van der Waals in conventional cases, a reaction efficiency is enhanced, a serum interference is suppressed in a capturing reaction, and the reaction time is shortened in a dissociating reaction. This invention can be adapted to an existing ultrahigh-sensitivity measuring technique.
