Title: Mri device
Inventor: USUI YOSHIYUKI
IPC: A61B10/00
Filed: 1987-09-30
Abstract: PURPOSE:To improve the utilization rate of a power source and to reduce the size of the MRI device by obtaining gradient magnetic field power supply for forming a gradient magnetic field in X, Y and Z direction from a common power source part. CONSTITUTION:Gradient coils 1, 2, and 3 of three channels are supplied with electric power from the common power source part 7 through amplifier parts 4b, 5b and 6b of the respective channels. At this time, the electric power is twice for the X channel, 2.67 times for the Y channel, and three times for the Z channels as large as when the magnetic field is neither tilted nor slowed. When an output current is congested to a specific channel, output currents of other channels may be small, so the common power source part 7 handles them sufficiently when having capacity three times as large as the standardized electric power of each channel. Therefore, the electric capacity is less than when power source parts are provided in every channel, the utilization efficiency of the power source is improved, and the device is reduced in size and weight.

IPC: H05K3/34
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To provide a mounting substrate formed into such a structure that a package is always bonded by soldering to the substrate in a prescribed bonding strength. SOLUTION: A mounting substrate 36 is a mounting substrate of a structure, wherein a projected solder land 12 having a bonding surface on an upper surface 13 thereof and an electrically insulavite protective film with an opening 38, through which the land 12 is made to expose and covers the surface of the substrate, are provided on the substrate and a CSP is bonded by soldering to the land 12 by a reflow soldering method. The interval (d) between a sidewall 26 of the land 12 and the open wall of the opening which opposes to the sidewall 26 is set in an extent of 20 to 50 μm. When the CSP is mounted on the substrate 36, a solder is made to weld to the solder bonding surfaces of the CSP to the upper surface 13 and sidewalls 26 of the land 12 to bond by soldering the CSP to the substrate 36 whereby the CSP is mounted on the substrate 36.  As the solder is always melted on the upper surface 13 and the sidewalls 26 of the land 12, the prescribed solder bonding strength of the CSP to the substrate can be always achieved.

Title: Drive controller for stepping motor
Inventor: TSUGITA KOUSAKU
IPC: H02P8/14
Filed: 1983-12-26
Abstract: PURPOSE:To diminish a power source capacity for a stepping motor by reducing a drive current at a constant speed time as compared with that at accelerating or decelerating time. CONSTITUTION:When a stepping motor 19 is in an accelerating state, a control signal C is low level. Accordingly, a reference voltage is set to a relatively high level. Thus, a drive current I supplied to the exciting winding of the motor 19 becomes a relatively large current. When shifted to a constant speed state, a control signal C of high level is supplied to a controller 18. Thus, the reference voltage of a comparator becomes lower level from the potential at the accelerating time. The drive current I supplied to the exciting winding of the motor 19 is held in a low level state as compared with that at the accelerating time.

Title: Device for calibrating touch panel
Inventor: KURODA HISASUKE
IPC: G06K11/06
Filed: 1990-09-14
Abstract: PURPOSE:To automatically calibrate the positional information of a touch panel in another image system by selecting one of plural image systems having respectively different display parameters as a reference, and obtaining the correction value of positional information between both the systems based upon respective display parameters between the selected system and the other image system. CONSTITUTION:A display area 4Gr in a CG image (a different medium image) system to be used as a reference on the screen of a display 3 is generally shifted from a display area 4Gi in a switched CG system. The shift corresponds to the display parameters of respective CG systems and is expressed by distances and azimuth from the display start points Pre, Pi of respective systems on the screen. Thereby, the correction value of a panel coordinate value in the switched CG system can be obtained based upon the display coordinates (R0, S0) of the display start point Pi in the switched system and the display coordinates (U0, W0) of the display start point Pre of the reference system. Thus, the panel coordinates of the other CG system can be automatically calibrated.

Title: Shift lever lock device for prevention of unrighteous use
Inventor: KITO SHOZO
IPC: B60R25/24
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent unrighteous use of a vehicle by locking a shift lever. SOLUTION: When an immobilizer key K1 is inserted into a key cylinder 2 of this shift lever lock device 1 for unrighteous use prevention, an immobilizer identification code is transmitted from a transponder T of the immobilizer key K1 to an immobilizer controller 5. The immobilizer controller 5 compares an vehicle-side identification code previously registered in its own EPROM with the immobilizer identification code transmitted from the key. If an improper key is used, the two identification codes do not conform to each other, and therefore the immobilizer controller 5 maintains the state of the shift lever locked by a shift-lever lock solenoid 6.

The current value is determined by the electrodes 3, 4 and is converted to a voltage value in a signal processing part 7. The value is displayed on a display part 8. Since the value thus obtd. is the value corresponding to the concn. of the hydrogen peroxide existing in the reaction liquid, the concn. of the component is determined from the voltage obtd. in such a manner.

Title: Production of clad steel plate
Inventor: KOSEKI TOMOYA
IPC: B21B1/22
Filed: 1983-12-29
Abstract: PURPOSE:To produce a clad steel plate at a high yield without generating defecting joining by passing the thinner plate material to a high speed roll side in different circumferential speed rolling in which the circumferential speeds between an upper roll and a lower roll are different in a specific range. CONSTITUTION:A base metal and a clad metal are subjected to different circumferential speed rolling in which the circumferential speeds of an upper roll 5 and a lower roll 6 are different in a >=10% and <=30% range in the stage of producing a clad steel plate by joining the base metal and the cladding metal by hot rolling. The blank material having the thinner thickness of the base metal and the cladding metal is passed to the high speed roll 5 side in the stage of performing such different circumferential speed rolling. A large slip deformation is thus generated on the roll 5 side. A large slip deformation is therefore generated with the joint surfaces by which the base metal and the cladding metal are more strongly joined.
