Title: Marking apparatus
Inventor: KYOGOKU YOSHIAKI
IPC: G01M1/26
Filed: 1989-02-04
Abstract: PURPOSE:To obtain an apparatus wherein a marking unit is freely moved to an arbitrary position by controlling the moving amount of a moving means based on an unbalanced angular position signal outputted from a dynamic balancing machine. CONSTITUTION:A moving means comprises an X-direction moving member 26 and a Y-direction moving member 27 which are controlled with a moving- amount controlling circuit 37. An upper marking unit 23 is moved by an arbitrary amount in the orthogonal two directions by the moving means. The unbalanced angular position which is measured with a dynamic balancing machine is marked on a work piece 14 which is set on a stage with the marking unit 23. The moving-amount controlling circuit 3 controls the moving amounts of the moving members 26 and 27 so that the upper marking unit 23 is located at a position facing the unbalanced angular position of the work piece 14 based on the unbalanced angular position signal that is outputted from the dynamic balancing machine. Since the unbalanced angular position can be marked with the work piece 14 being fixed at the specified position, excessive loads are not applied on the main body of the dynamic balancing machine.

Filed: 1981-02-24
Abstract: PURPOSE:To reduce the size of a stepping motor and to save the power of the motor by effectively collecting an intermittently stepping-out phenomenon only when an instantaneous load is applied to the motor. CONSTITUTION:A pulse controller 12 applies a control pulse of normal or reverse rotation to a stepping motor 7a through a motor driving circuit 11.

Title: Right angle phase radio frequency coil and magnetic resonance imaging apparatus
Inventor: ARAKAWA MITSUAKI
IPC: G01R33/36
Filed: 1987-02-09
Abstract: First and second co-located axially and circumferentially extending RF coils (10) are displaced spatially with respect to one another by 90 degrees so as to produce a pair of RF signals from the enclosed generally cylindrical volume which are in phase quadrature. Each of the coils includes four spaced-apart and generally parallel leg sections (L, to L<sub>4</sub>; L'<sub>1</sub> to L'<sub>4</sub>). The same coils (10) or one of them may also be utilized for transmitting NMR RF signals into the same volume. The coils have a common open-end through which objects to be imaged may be inserted and a common "closed" end for convenient location of RF coupling and feeding structures. Each of the coils (10) has an RF feedline structure (14, 16) which extends across a diameter of common closed end and the two feedline structures are disposed substantially perpendicular with respect to one another so as to minimize cross coupling. The feedlines are also spatially configured to faciliate mounting of associated tuning (Cp, C<sub>f</sub>) and coupling (C<sub>1</sub>, C<sub>2</sub>, C<sub>a</sub>, C<sub>b</sub>) capacitors. A fixed coupling "paddle" provides cancellation coupling between the coils and a movably mounted coupling paddle is arranged to provide variable amounts of cancellation coupling between the orthogonal feedline structures. The phase guadrature RF signals emanating from the pair of coils are preferably amplified before being combined in a 90° RF hybrid circuit.

Abstract: PURPOSE:To lock an insertion auxiliary appliance in an edge optical adapter so as to surely prevent it from falling even if the insertion auxiliary appliance attached to an endoscope is detached by setting the minimum inner diameter of the insertion auxiliary appliance to the maximum outer diameter of the edge optical adapter or less. CONSTITUTION:A part of the lock hole 110 of a stopper 104 enters the groove part 103 of the endoscope 2 to be in a locking state.

In such a state, the inner diameter L's of the lock hole 110 of the stopper 104 is a little smaller than the outer diameter La of the edge optical adapter 21. Namely, La>Ls holds. Even if the attachment of the insertion auxiliary appliance 22 by an insertion auxiliary appliance attachment part 14 is loosened, said appliance 22 can be prevented from falling as long as the edge optical adapter 21 is not detached from the edge part 11. Therefore, the insertion auxiliary appliance 22 can be surely prevented from falling, thereby accomplishing a safe endoscope.

Abstract: PROBLEM TO BE SOLVED: To transfer fast the data on a bus with reduction of waveform distortions without using a terminating resistance that increase the heating value nor a driver/receiver element of large driving capability by performing a switch control so as to define a semiconductor circuit being a drive source as the end point of a bus transmission line. SOLUTION: On a signal transmission line of a bus, the switches are inserted among IC11 to IC16 and the bus is connected in a loop form via these switches. At the same time the open/close actions of switches are carried out in matching with the output operations of every IC. That is, the drive signals dr1 to dr6 used for the driver/receiver circuits of every IC are sent out to the switches SW1 to SW6 to open and close these switches. As a result, when one of ICs connected to the bus serves as a drive source, the switches adjacent to the drive source IC are turned off with all other switches turned on respectively.

Title: Fuel flow regulator for engine
Inventor: HAKAMATA KIYOUJI
IPC: F02M7/12
Filed: 1984-02-17
Abstract: PURPOSE:To feed auxiliary fuel to an engine in time of starting and decelerating with one device alone, by installing an auxiliary fuel passage in addition to a main fuel passage of a carburetor, while setting up a valve, which opens at both low and high suction pressure times, in the said passage. CONSTITUTION:Aside from a main fuel passage 23 of a carburetor 21, a pipe 28 having a control valve 29 is installed in the point midway, setting it down to a fuel system for air-fuel ratio compensation. A valve body 38 is designed to act in a normally opened direction by dint of a spring 40, while it also works in a closed direction by suction pressure in a suction pressure chamber 35 of a diaphragm 34 otherwise. In time of engine starting, since the suction pressure inside a crank chamber 15 is still low, the inside of this chamber 35 is approximate to the atmosphere whereby the valve body 38 opens and feeds auxiliary fuel from the pipe 28. At the time of normal operation, the valve body 38 closes due to the suction pressure inside the chamber 35. In order to cope with a shortage of stopgap fuel ranging from time of deceleration till acceleration, strong suction pressure inside the chamber 35 opens an atmospheric relief valve 46, making the chamber 35 into the atmosphere, whereby the valve body 38 is opened and the auxiliary fuel is fed to the carburetor.
