Title: Squelch circuit and multimode receiver equipped with the squelch circuit
Inventor: NAKATANI MITSUHIRO
IPC: H04B1/10
Filed: 1988-12-30
Abstract: PURPOSE:To accurately operate even for a weak input signal by detecting a noise component out of an IF signal and intermittently controlling a demodulated signal. CONSTITUTION:Since the noise component is small when the signal intensity of a received FM radio wave is strong, an FMw noise signal (f) is small, and a noise detected signal (k) is also small. Therefore, the noise detected signal (k) is smaller than a squelch operation level (m), and a squelch actuating signal (n) is not outputted. Since the noise component becomes larger when no signal component exists in the received FM radio wave, the FMw noise signal (f) is large, and the noise detected signal (k) is also large. Therefore, the noise detected signal (k) is larger than the squelch operation level (m), the squelch actuation signal (n) is outputted, and an FMw demodulated signal (d) is interrupted in an AF signal intermitter 55 and never drives a speaker 7. Thus, the title squelch circuit, which can execute a squelch operation even for the weak input signal and has high sensitivity, can be obtained.

Title: Feature point detecting method for figure-shaped pattern
Inventor: SAWANOI YUKIYA
IPC: G06T7/60
Filed: 1988-12-28
Abstract: PURPOSE:To make a mask for detecting a feature point and a large-scale hardware unnecessary by detecting the feature point by dividing the quantized picture of a figure-shaped pattern into plural small area, and deciding whether a point is the feature point or not according to relation between borders from/at which contour trace is started and finished in each small area. CONSTITUTION:A picture input part 1 picture-inputs a fingerprint, and its input picture is binarized by a quantizing part 2, and is stored in a picture memory 3. A contour tracing part 4 divides the quantized picture of the figure-shaped pattern into plural rectangular small areas, and traces the contour of the picture in the small area from the border of each small area as storing the point most distant from this border until it reaches any border. A feature point detecting part 5 discriminates whether the most distant point is the feature point or not based on the relation between the borders from/at which the contour trace is started and finished, and detects the feature point. Thus, many pieces of the masks for detecting the feature point or the like are not necessitated, and besides, the complicated and large-scale hardware too is not necessitated, and small quantity of processing for one picture is enough as well.

Title: Warming roll
Inventor: YANO MASASHI
IPC: B29K7/00
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To improve an operating efficiency by effectively winding a viscoelastic fluid on a roll at the time of starting warming of the fluid, increasing a gradient until the fluid arrives at a predetermined temperature and warming in a short time. SOLUTION: A gap is set between a pair of rolls 14 and 16 to regulate a warming degree of a rubber and to guide an axial direction movement of the rolls. A retention of the rubber is aided by forming a plurality of ring-like grooves 34 on a rubber introducing region. A shearing force is given to the rubber intruded between the pair of the rolls 14 and 16. Thus, since it is warped back to easily wind the rubber on the one roll 14 side, a change rate (gradient) of the warming degree at an initial time of introducing the rubber becomes larger (sharp gradient) than that in prior art, thereby shortening a warming completing time.
