Patent CA-1326514-C (CA)
Title: Automatic electrical power control circuit
Inventor: HOTTA TOSHINORI
IPC: G05F1/66
Filed: 1987-09-24
Granted: 1994-01-25
Abstract: ABSTRACT OF THE DISCLOSURE    A power control circuit comprises a signal input, a controllable attenuator, an amplifier, an output, a power detector, a reference circuit, a comparator, an external control input, an error detector, and a controller.  The comparator, error detector, and controller are digital circuits realized by a microprocessor.  The attenuator is between the signal input and the input to the amplifier to regulate the amplifier's output.          The power detector couples to the amplifier output to generate a measurement signal representing the power at the output.  The reference circuit generates a reference signal representing a predetermined minimum output when the signal input is nonzero.          The comparator compares the measurement and reference signals and generates a decision signal indicating if the signal input is nonzero.  The external control input receives an external control signal.  The error detector is coupled to the power detector and the external control input and computes the difference between the external control signal and the measurement signal.  When the measurement signal is at or above the minimum power, the controller provides an integral of the computed difference to control the variable attenuator.  When the measurement signal is below the minimum power, the controller keeps the attenuator at a prior constant value.

Granted: 1993-08-24
Abstract: ABSTRACT OF THE DISCLOSURE         In order to calibrate an appliance for measuring force or moment, the measuring element (1 carries a strain gage bridge (R1, R2, R3, R4) for delivering a signal which is mainly sensitive to the force or to the moment to be measured and is provided at the time of manufacture with two other strain-gage bridges (R5, R6, R7, R8,) ; (R9, R10, R11, R12,) for delivering signals which are mainly sensitive to two parasitic stresses other than the force or the moment to be measured.          In a first stage, the method consists in measuring the signals delivered by the three strain-gage bridges in the absence of any load applied on the measuring element, then under a number of known reference loads chosen from among those to which each strain-gage bridge is the most sensitive.  In a second stage, the reference measurements are used as a basis for calculating the parameters of sensitivity according to which each of the signals delivered by the measuring bridges is a function of the applied loads.  In a third stage, these parameters of sensitivity are used as a basis for calculating the correction to be made in the force or the moment measured by the first strain-gage bridge (R1, R2, R3, R4).

Abstract: SELF-PLUGGING BLIND FASTENER               ABSTRACT OF THE DISCLOSURE     A self-plugging blind fastener of the type having a tubular , headed, body,  and a stem which is pulled and locked relative  to the body  to  set  the  fastener,  has improved locking  means  provided  in  the  form  of  a deformable annular locking collar which is disposed on the stem, a locking groove on the plug part of the stem, and an annular recess at the head end of the body provided as an enlargement of the bore.   The recess has a generally cylindrical outer region of substantially greater diameter than the main region of the bore,  and a tapered inner region in which the diameter of the recess reduces to that of the main region of the bore.  The recess can be stepped between the outer and inner regions.  The locking collar has a locking portion of small external diameter which seats in the inner region of  the recess,  and a load-bearing head portion of larger diameter, and more massive, than the locking portion, but which can be forced into the outer region of the recess, causing the locking portion to be urged  radially  inwardly.    The  locking  portion  is supported by the stem until the locking groove comes into register with the recess, after which the collar can be forced further into the recess which guides the locking portion into the locking groove where it meets a reaction P.332/NA     face of the groove and then back-fills the groove to abut a locking face.   Stop faces on the stem and body ensure that the  locking  groove  registers  correctly  with  the recess.  The fastener can be set by a single action tool which pulls the stem and applies reaction force to the collar only. Figure 6.     P.332/NA

The telephone subset in conjunction with various subset buttons which control the mode selector is capable of operating in different modes.    Due  to  the  high  resolution  and  large capacity of the display one can now present pages of stored telephone numbers which essentially enables a user to select any number by means of a movable cursor and by pressing another  subset  button  can  immediately  dial  that  number.          Other modes provide credit card storage which are accessible and displayed as well as other privacy operative modes which are implemented by means of the high resolution display, microprocessor and associated circuitry.
