Title: Insulated gate field effect transistor
Inventor: MATSUMOTO SATOSHI
IPC: H01L29/786
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To eliminate the consumption of unnecessary power by a method, wherein when a control voltage is a value for making a part between a drain electrode and an electrode for a source and for applying a back gate voltage to be an 'off state', the value is so set that a depletion layer is formed in a channel region. SOLUTION: When a control voltage from a control voltage source takes '1' in binary representation, an N channel stretches from a gate insulating film 8 to a part of a channel region 5 between a source region 5 and a drain region 4, and is formed widely, when compared with the case that the control voltage takes '0' in binary expression. As a result the source region 3 and the drain region 4 can be controlled to be in on-state or an off state, by setting the control voltage as the binary '1' representation or the binary '0' representation, respectively. Hence it can be controlled that a large current be supplied to a load with '1' or a sufficiently small current be supplied to the load with '0', so that power is not consumed unnecessarily.

Title: Power supply unit for ac input
Inventor: SAGANE TOMIYASU
IPC: H02H9/02
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for providing the tertiary coil winding of a power conversion transformer and a resistor for suppressing a rush current by controlling the conduction resistance of a resistance control circuit according to the output of a charge/discharge circuit. SOLUTION: When a power supply switch SW1 is thrown SW1 is thrown, a current is supplied to a second rectifying circuit 5, a voltage applied to an internal capacitor gradually increases, and the voltage is applied to a resistance control circuit 6 as a limited voltage. Since a small voltage applied initially, the conduction resistance of the resistance control circuit 6 is extremely large, and a rush current is suppressed due to the large resistance of the resistance control circuit 6, thus suppressing a current IP that flows through the resistance control circuit 6. Also, since a current-suppressing resistor and the tertiary coil winding of a power conversion transformer are not required, a device can be miniaturized.

Title: B/f separating system of immunity measuring apparatus
Inventor: MATSUMOTO KOJI
IPC: G01N33/553
Filed: 1990-11-28
Abstract: PURPOSE:To simplify a B/F separation process and also to improve the precision in B/F separation by making magnetic particles (MP) migrate by an operation of switching the position of generation of a magnetic force by a magnetic force source on the occasion of the B/F separation. CONSTITUTION:After MP is once made to gather on the inner wall of a reaction vessel 2 by a magnetic force of a magnet 3, the content solution in the vessel 2 is discharged through an inner tube of a coaxial nozzle 5 and further a cleaning liquid is injected into the vessel through an outer tube of the nozzle 5. Subsequently, the position of disposition of the magnet 3 is changed at an angle of 180 degrees and MP migration is made to occur in a process wherein the MP is made to gather on the inner wall on the other side of the vessel 2 by the magnetic force of the magnet 3. Thereby an antibody or an antigen contained in the MP once made to gather is released into the cleaning liquid. On the occasion, the time for migration under the magnetic force is several times shorter than that of MP in the case when it is diffused, since a magnetic substrate is used as a nucleus of the MP in this case. Thereafter the content solution of the vessel 2 is discharged through the inner tube of the nozzle 5, the cleaning liquid is injected into the vessel 2 through the outer tube, and thereby execution of B/F separation is enabled.

Title: Touch signal probe
Inventor: NISHIMURA KUNITOSHI
IPC: G01B21/00
Filed: 1994-12-27
Abstract: PURPOSE: To improve the reliability and the accuracy as well as to realize a small size of structure and a low cost, by providing the position regulating mechanism of a movable member to which a stylus is installed. CONSTITUTION: In the probe case 1 of a touch signal probe, a position regulating mechanism 8 to convert the position of a movable member 6 a stylus 5 is installed is provided. In the measuring time, when a contact 4 at the tip of the stylus 5 is contacted to an article to be measured, its position is read. In this case, when the contact 4 is contacted to the article to be measured at a specific measuring force, the first convergence 16 of a seating mechanism 7 is separated from the second convergence 12 against the seating force, so as to prevent a damage by an error operation of the stylus 5. Even though the first convergence 16 is separated from the second convergence 12 against the seating force, the convergence 16 is never removed from the convergence 12, because the posture of the movable member 6 is maintained by the position regulating mechanism 8.  When the contact of the contact 4 to the article to be measured is released, the convergence 16 is set still at the convergence 12 by the seating force.
