Title: Printing head for wire dot printer
Inventor: SATOU KAZUHIDE
IPC: B41J2/28
Filed: 1984-02-06
Abstract: PURPOSE:To arrange so that a release current may be reduced regardless of the number of simultaneous printing dots by splitting a yoke for a magnetic circuit constituting a printing head every time the yoke is opposed to each armature and arranging such yokes at a fixed distance from each other. CONSTITUTION:A yoke opposed to each armature is of a split-type yoke 16 and such yokes are independently separated from each other. In addition, these yokes 16 are arranged at a gap of distance (x) provided and the wider the gap (x) is, the higher effect. However, if the gap (x) is selectively set at approx. 0.1mm., an increase in the release current by a magnetic interference can be reduced significantly. As a result, each yoke is separated from another yoke and a magnetic permeance between the yokes is lessened. In addition, the impact of a change in the magnetic field intensity of a yoke during the drive cannot be easily transferred and the printing head can be driven at almost a constant release current regardless of the number of simultaneous printing dots.

Suppose that TRs Q1', Q2', Q6', Q7' are matched with each other, the relation of IB'1=IB'7 is obtained. Thus, output currents I1', I2' of the current mirror circuit 10 are made equal to each other. Further, even if current amplification factors B1', B2' of the 1st and the 4th TRQ1', Q7' are unmatched, the difference between the output currents I1' and I2' can be very small. Thus, the output currents I1', I2' are made equal to each other, and when a phase comparison input of the same phase is inputted to input terminals 3, 4, the offset voltage appearing at an output terminal 5 is zeroed.

Title: Measuring device for wind pressure around body
Inventor: SUMIYA KEIJI
IPC: G01P5/16
Filed: 1984-02-07
Abstract: PURPOSE:To measure wind pressure accurately without using a detector which detects a burble phenomenon by calculating the standard deviation of sampling data on the wind pressure due to a pitot pipe and using it for decision making when the wind pressure of a model of a vehicle is measured. CONSTITUTION:The model of the automobile is put in a wind tunnel and the pitot pipe is moved around the model to obtain sampling data on the air pressure. At this time, the burble phenomenon occurs at a measurement point after the pitot pipe moves. Then, sampling data are obtained at numbers of measurement points for the wind pressure of the pitot pipe to calculate the standard deviation deltat. When the wind flows uniformly without any burble phenomenon, the standard deviation deltamu of the wind pressure data is inputted to a decision means previously. When the measured standard deviation deltat is smaller than a decision level 3deltamu, the decision means decides that no burble phenomenon occurs and the measurement, is normal, and also calculates the means value. Further, wnen the measured standard deviation is larger than 3deltamu, the data are sampled again a specific time later. Thus, it is decided whether the burble phenomenon occurs from the standard deviation, so the wind pressure is measured precisely.
