Title: Mri device
Inventor: SAITO YASUMASA
IPC: G01R33/28
Filed: 1991-05-21
Abstract: PURPOSE:To enable a magnetic body to be discovered before picking up images in order to prevent magnetic field distortion and image distortion due to the influence of the magnetic body when a subject wearing the magnetic body on part of his body or clothes enters a uniform magnetostatic field. CONSTITUTION:When a Hall element 1 is placed in a static magnetic field B and a current I is passed in the perpendicular direction to the magnetic field B, a constant voltage is generated in the perpendicular direction to the two directions of the magnetic field B and the current I. Under these conditions a magnetic body is placed in the static magnetic field and then the distribution of the magnetic field is changed and the output voltage of the Hall element 1 is changed. The change in the output voltage is detected whereby the presence of the magnetic body inside the magnetic field B can be detected. Therefore, the influence of static magnetic field distortion on images can be eliminated by removing the magnetic body before picking up the images.

Title: Loop detecting circuit
Inventor: KAWAMI SHIGERU
IPC: H04Q3/72
Filed: 1987-06-10
Abstract: PURPOSE:To detect a loop irrespective of a direction for passing a loop current by rectifying the both end voltage of a feeding resistance and eliminating an influence due to the inversion of a feeding voltage polarity. CONSTITUTION:When a pole changing feeder circuit BA inverts the feeding voltage polarity, supplies a supply voltage to the feeding resistance RB and supplies an earth to the feeding resistance RA, the direction of the loop current I1 is inverted to pass from the feeding resistance RA to the feeding resistance RB, both the end voltage of the feeding resistance RB, RA is rectified by rectifying means DB, DA, and inputted to differential amplifiers OPB, OPA with the same input voltage polarity as that before the inversion of the feeding voltage polarity, so that the loop is detected without the influence of the inversion of the feeding voltage polarity of the pole changing feeder circuit BA. In such a way, a loop detecting circuit in which an A line and a B line are switched by a relay or the like to invert no feeding voltage polarity and the electronized pole changing feeder circuit is used to employ for the feeder circuit for inverting the feeding voltage polarity, is obtained.

Title: Aligning feeder for cylindrical member
Inventor: OE TAKAHITO
IPC: B65G47/14
Filed: 1988-06-10
Abstract: PURPOSE:To enable a high-speed supply in a marking device for a magnetic cylindrical member such as a can made of sheet metal by carrying an upright can on a rotating disc along an aligning guide, and making a magnet act on the can bottom near a delivery port from the disc center so as to send the can into a delivery guide. CONSTITUTION:When a rotating disc 3 and a disc 9 having a magnet 12 are rotated in the direction of the arrow, cans W on the rotating disc 3 are moved to a delivery guide 16 with aligning along an aligning guide 13 due to its centrifugal force and the autorotation by the friction with the disc 3. On the other hand, the magnet 12 mounted to the disc 9 adsorbs the cans W near the center of the rotating disc 3, and sends them to the delivery guide 16. Also, the cans W near the delivery guide 16 receive a carrying force by the adsorption force of the magnet 12. The cans W are separated one by one by the curved delivery port 15 of the delivery guide 16 and sent into the delivery guide 16. Hence, the cans can be supplied at high speed without receiving damages.

Title: Reproducing amplifier circuit
Inventor: KATOU NOBUYOSHI
IPC: G11B20/10
Filed: 1990-06-01
Abstract: PURPOSE:To prevent the excessive heat generation of another part or the leakage of an unnecessary signal by supplying power only to a specified preamplifier, setting it in an operational state and preventing any unnecessary current from being supplied to the other amplifier by setting a control circuit. CONSTITUTION:When a signal reproduced from a reproducing head 1 is outputted to an output terminal 4, a control signal A at an 'H' level of a waveform 401 is applied to preamplifier 102. This amplifier 102 is constituted so as to be supplied the circuit current only when the input of the control signal is 'H', and after supplying this current, the amplifier is turned to the operational state for the first time. Such circuit current control can be easily constituted by using a current control circuit such as a current mirror circuit or the like. Since the level of the other control signal is 'L' at such a time, the other preamplifier including 112 is turned to an inactive state. By designing to turn to a high impedance state, for example, so as not to affect the other outputs by the output of each preamplifier in this inactive state, the output terminals of all the preamplifiers are made common and defined as the output terminal 4 of the reproducing amplifying circuit.

Title: Device and method to limit gain in digital gamma correction device
Inventor: ROBAATO JIYOOZEFU TOTSUPAA
IPC: H04N5/202
Filed: 1993-06-16
Abstract: PURPOSE:To reduce a signal noise substantially in a dark level portion of a reproduced picture. CONSTITUTION:A gamma index value, a black level, a white level and a desired maximum gain are selected. A possible count of an input signal value is decided. A corrected black level is set equal to the desired black level. A gain limit value for a gamma correction transformation function is calculated and a minimum input signal in which a given gain is equal to the gain limit or smaller is decided. The black level correction coefficient is calculated. The correction black level is increased by the black level correction coefficient portion and whether or not the black level is decreased more than a prescribed threshold level is decided. The gamma correction coefficient is calculated again and the succeeding black level correction is added till the coefficient reaches a correction threshold level. The final conversion function increases linearly to a video signal value in the vicinity of the desired black level and a gain equal to the gain limit value is obtained. The gamma function increases nonlinearly at the reduction rate in the vicinity of the white level.

IPC: G01N33/543
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To suppress the influence of a substance for causing non-specifical reaction in an organism sample by including alkylglycoside surface-active agent or steroid surfaceactive agent in a solid-phase detergent liquid for immunological measurement. SOLUTION: A solid-phase detergent liquid for immunological measurement contains alkylglycoside surface-active agent or steroid surface-active agent. For example, N-actylβ-D glycopyranosido, n-nonyl-β-D-maltopyranosido, and n-decyl-β-Dglycopyranosido are used for an alkylglycosido surface-active agent. For example, cholic acid salt, deoxycholic acid salt, and dehydorocholic acid salt are used as a steroid surfaceactive agent. These can be used individually or in combination. For example, phosphoric acid buffer agent, tris' buffer agent, and Good buffer agent are contained in addition to surface-active agents, thus suppressing the influence of a substance for causing a nonspherical reaction in an organism sample and achieving an accurate measurement.

Title: Exclusive control system
Inventor: NAKAGAWA AKIKAZU
IPC: G06F9/50
Filed: 1984-07-14
Abstract: PURPOSE:To avoid the deterioration in processing response performance by putting a processing request having lower priority, if given under the use of resources, into a position before own place with a dispatch queue when access is given to the resources. CONSTITUTION:A processing request A has priority 4 higher than a processing request C (priority 2) and therefore can be processed earlier than the request C in case the request C is set under an execution enable state with other requests A and B (priority 3) kept under a phenomenon queue state respectively. Then the priority of the request C is raised up to 4 equal to the request A to be processed earlier since the request is kept under a busy state when the request A gives access to the resources. Then the request C of priority 4 is processed earlier although the request C of priority 3 can be already executed. When the application of resources is through with the request C, the priority of the request C is reset to its original 2. Then the request A of priority 4 is processed.
