Title: Speed indicator
Inventor: WATAYA SEISHI
IPC: G01P5/00
Filed: 1990-03-09
Abstract: PURPOSE:To increase the degree of freedom of wearing on a human body and to easily measure a moving speed by detecting wind pressure that a moving body receives as differential pressure by a diaphragm and calculating the moving speed. CONSTITUTION:A pressure sensor 1 is arranged at the edge part S of the diaphragm 1a which is made thin at the center part of a silicon chip so that diffusion resistances Ra, Rb, Rc, and Rd are in the same length direction, thus constituting a bridge circuit. The diffusion resistances are strain gauges which utilize piezoelectric effect and vary in resistance value with the differential pressure P1-P0 between pressure P1 applied to one surface of the diaphragm 1a and atmospheric pressure P0 applied to the other surface according to the speed of the moving body. The output voltage obtained by processing variations in potential at points e1 and e2 of the bridge circuit with the differential pressure by amplification 2 is proportional to the differential pressure P1-P0, so an arithmetic means 3 calculates the speed of the moving body by using an expression based upon the Verneuil's theorem.

Title: Mode display mechanism capable of preset
Inventor: WATANABE KAZUO
IPC: H04B1/16
Filed: 1980-05-07
Abstract: PURPOSE: To recognize the working mode with no confusion, by performing a preset enable mode display for a digital display radio receiver or the like by blinking a display element for display of reception frequency.  
     CONSTITUTION: A control circuit 8 secures a synchronism for a segment signal S with a digit signal D to deliver the signal S and displays the reception frequency through a display element 1 via a segment driver circuit 2 and a digit driver circuit 3. In this case, the signal P2 of a pulse generating circuit 6 is set at H (high) level. The circuit 8 applies a signal P1 to the circuit 6 after discriminating that a key is pushed in a preset key group 7 by an output signal O and an input signal I, and thus produces a signal P2 having a prescribed pulse duration. This output P2 is supplied to the element 1 via an AND gate circuit 5 and the circuit 3, and thus the reception frequency under a display mode is blinked according to a prescribed pulse duration. When a presetting operation is through, the circuit 8 discontinues the generation of signal P1. Then the signal P2 is kept at H level, and the element 1 displays the reception frequency as usual.

Title: Compressing and expanding circuit for signal
Inventor: TAKIZAWA YOSHIYUKI
IPC: H03G7/00
Filed: 1980-05-08
Abstract: PURPOSE:To change the dynamic range of signal, by decreasing the signal with a compressor to the main line of a compressor and expander used for a low range of the noise given from a transmitting medium and increasing the signal with an expander to secure a complement with the compressor side and thus preserving an interchangeability for the reference level. CONSTITUTION:A compressor 1 to which the signal X2 is supplied consists of a main signal path 11' and the secondary signal path 12 and obtains the level compressed signal Y2 which is fed forward. This output Y2 is supplied to an expander 2 through a transmitting medium T. The expander 2 consists of a main signal path 21' and the secondary signal path 22, and obtains the level expanded signal Z2 which is fed forward. The secondary signal paths 12 and 22 give the frequency characteristic to a signal and then deforms the signal nonlinear. The path 11' consists of a circuit having the input/output terminals Vi(S) and Vo(S) and reduces the pass signal. And the path 21' consists of a circuit having the input terminals Vi'(S) and Vo'(S) and increases the pass signal in complement to the path 11'. Thus an interchangeability is preserved for the reference level, and the dynamic range can be changed for a signal.

IPC: H03G9/02
Filed: 1980-05-08
Abstract: PURPOSE:To prevent the occurrence of a distortion due to saturation, by securing a compression and expansion even for a high input signal in a high frequency region. CONSTITUTION:An input signal X2 passes through the main signal path 11' having a transmission function K(S) and also the secondary signal path 12 having a transmission function F(S) in a compressor 1 to be added in a feed-forward way and thus to obtain a level compressed signal Y2. At the same time, the signal passes through the main signal path 21' having a transmission function 1/K(S) is made to pass through the secondary signal path 22 having a transmission function F(S) in an expander 2 to be subtracted in a feedback way and thus to obtain an expanded signal Z2. In other words, Y2=[K(S)+F(S)]X2 and Z2=Y2/[K(S)+F(S)] are satisfied. As a result, the signal X2 becomes equal to the signal Z2 to obtain an output signal Z2 identical with the input signal X2.
