Title: Motor current sensor for motor-driven switching device controller
Inventor: KUWAYAMA AIICHIRO
IPC: H02P29/00
Filed: 1991-04-16
Abstract: PURPOSE:To provide a motor current sensor for an input/output insulation type motor-driven switching device controller for both AC/DC, having a small loss and a small size by solving subjects of a current transformer, a Hall element, etc. CONSTITUTION:A motor driving power source 12, a motor 13, a first winding of a saturable transformer 14 are connected in series, and high frequency impedance sensing means 15 is connected to a second winding of the transformer 14. A high frequency impedance of the second winding of the transformer 14 is high when a motor current is interrupted. When the current flows, a core is magnetically saturated to lower the current, which is sensed by the means 15. Since the sensing of the current is executed by magnetic saturation of the core, it can be sensed by both AC/DC, the core which has a small size for causing the magnetic saturation by a small current, can be used, and the motor current flows only to the first winding. Thus, its loss is small, and an electric connection between the two windings is facilitated.

Filed: 1979-07-03
Abstract: PURPOSE: To make it possible to effectively utilize the quantity of light of a light source by providing two sheets of shutter plates of variable mutual position relations and automatically changing over these at the forward projecting and at the backward projecting.  
     CONSTITUTION: A stationary shutter plate 25 rotates integrally with a drive shaft 2, and a movable shutter plate 23 is also driven by the drive shaft 2, but at the reversing, it is rotatively driven with delay of a fixed angle by a slot 23d. This delay angle creates a deviation between the two plates 23 and 25, thus forming the main plate and the flicker plate of the widths differing at the forward projecting and at the backward projecting. In this way, an aperture 16 may be covered only for a minimum required time at each of the forward feeding and the backward feeding of the film; hence, the quantity of light of a light source may be utilized effectively.

Title: Triangular wave generating circuit
Inventor: MIYAKE TOSHIHIDE
IPC: H03K4/06
Filed: 1985-04-20
Abstract: PURPOSE:To generate the functional waveform of a triangular wave having a large amplitude by providing the 1st and the 2nd constant current circuits which detect the saturation of a transistor (TR) and turn on and off by the saturation, driving an RS flip-flop circuit with a saturation output, and controlling the on/off state of a constant current source. CONSTITUTION:The area ratio of the emitters of TRs Q5 and Q7 is so determined that the collector current IC(Q7) of the Q7 is larger than that of a Q9, so the saturation of the Q7 is detected. When the set input terminal S of the RS flip-flop circuit 3 rises to a level 'H', the output terminal Q rises to 'H', so a Q10 turns on and the Q6 and Q7 turn off to charge a capacitor C with the 1st collector current IC1(Q9) of the Q9; and the voltage of an output terminal OP1 rises with time and approximates to a voltage nearly equal to a source voltage +Vcc at time t2. The Q9 is saturated at time t3 and the reset input terminal R is held at 'H' through a terminal A for wiring and a resistance r9, so a Q10 turns off and the Q7 turns on. The capacitor C is discharged and the voltage at the output terminal OP1 approximates to zero V.

Title: Original conveying device
Inventor: YAMADA TAKANOBU
IPC: B65H5/06
Filed: 1987-04-07
Abstract: PURPOSE:To make it possible to correct the inclination of an original without the original being creased, broken, dirtied and so forth after insertion of the original, by attaching roller members for driven rollers, individually and rotatably on a support shaft. CONSTITUTION:Driven rollers formed of driven roller members 40 made of low friction coefficient synthetic resin are fitted rotatably on a stationary shaft 39. In this arrangement, if an original is inserted being inclined during insertion thereof, the roller member 40 of the driven of roller 23 making contact with the roller section 36 of a drive roller does not affect upon the roller member 40 making direct contact with the original even though it rotates, since the roller members 40 of the driven rollers 23 confronting a pair of original insertion rollers 21 may be individually rotated, and is rotated independently, following the displacement of parts of the original in association with the correction of inclination of the original. Accordingly, only a low resistance is effected, thereby it is possible to reduce a stress exerted to the original.

Title: Electronic hemadynamometer
Inventor: IWAI NOBUO
IPC: A61B5/022
Filed: 1990-03-30
Abstract: PURPOSE:To enable the determining of changes in blood pressure without error even when a period to be monitored differ by providing a means to switch a range of time base of a display means. CONSTITUTION:A display section 1 gives a numeral display of a maximum and minimum blood pressure measured when a measurement of a blood pressure ends. But a pressure data is displayed on a two-dimensional graph with the horizontal axis taken as time base 14 and the vertical axis as pressure axis 13 when the blood data stored into a memory means 12 are read and displayed and even when a measuring time interval differs, they are plotted at an equal interval. A changeover switch 5c switches display contents of the display section 1 between a numeral display of a blood pressure measured and a graph display of a measurement data stored in the memory means 12 and it also serves as a means of switching a range of the time base 14 of a graph to be displayed. Thus, when a long-term change is monitored, the switching means 5c is switched thereby allowing a long-term display of the measurement data with a larger range of the time base of the graph. When a short-term change is monitored, the range of the time base is switched short, thereby allowing display of a short-term measurement data alone.
