Title: Signal detector
Inventor: MAHAMUDO HATSUDEIDEI
IPC: H04B10/2507
Filed: 1980-05-27
Abstract: PURPOSE:To obtain a high-performance detector whose error rate is low, by detecting an input signal by using a function of a logarithmic tolerance rate to the input signal with regard to a system depending upon a message with a transmitted noise like an optical fiber communication system. CONSTITUTION:An input signal r(t) is inputted from a terminal 3 to filters 8 and 9 and a delay circuit 7. An estimated value output 10 is processed by multiplication 15 and addition 20, and an estimated value output 11 by multiplication 15 and addition 21. A delay output 12 is inputted to an adding and composint circuit 25 after multiplying processes 14 and 15 and also added 24 via load multiplying circuits 22 and 23 after adding processes 20 and 21 to input the sum to the circuit 25. An output obtained from the output of the circuit 25 by integration 26 is sampled 27 with a sampling clock fs in every integration period. The output of sampling 27 is compared with a preset threshold level by a comparing circuit 28 to obtain a detection signal with a logical level which corresponds to a dependent noise. A logarithmic tolerance ratio function thus generated is used to obtain a high-preformance signal detector having a low error rate.

Title: Water flow rate adjusting device
Inventor: MATSUI KOUJI
IPC: F24D3/10
Filed: 1984-04-09
Abstract: PURPOSE:To reduce variations in water flow rate with respect to vibrations in water pressure, and as well to aim at reducing the sound of flowing water, by providing a resistance member for adjusting the flow rate of water to a predetermined value, just below the downstream section of a water flow rate control section. CONSTITUTION:Water flows from a water feed connection port into a water flow rate control section composed of a burner housing 15, a core 16 and an O- ring 17, and therefore, the flow rate of water is adjusted with respect to variations in water pressure. If the flowing resistance of water flowing through the apparatus is changed, the sound of flowing water becomes high around the gap between the core 15 and the O-ring 17 within the water flow rate control section. However, by providing a resistance member 18 in conformity with the kind of the apparatus, the sound of flowing water may be made low. The resistance member 18 is in a container-like shape, having a large diameter hole 18a and small diameter holes 16b formed in the center and peripheral sections of the resistance member 18, respectively, and therefore, water discharge upon water bleed may be easily made.

Title: Rotational-speed control system in sensorless drive for delta-connection three-phase motor
Inventor: SAKURAI MIKI
IPC: H02P27/02
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To change rotational speeds into tens of times the starting rotational speed by detecting positive and negative counter electromotive forces generated at a motor terminal, compressing and magnifying the voltage signal of the counter electromotive force by means of a nonlinear element, and using it for a control feedback signal of the starting or rotational speed. SOLUTION: If positive and negative counter electromotive forces +dE11p, -dE11m which are detected from a motor are applied to a differential amplifier 12, differential voltage is converted to current, and is applied to an oscillating circuit 16 as a charging current 14 through a current mirror circuit 13. The oscillator 16 outputs pulse voltage of a cycle determined by the charging and discharging of a capacitor C15c, a resistor R15r, and a charging current I14 to an oscillating output 17. The voltage and current conversion characteristics of a differential amplifier 12 becomes the characteristics of a diode, and the current after the conversion changes exponentially. At the time of activation start of a motor, the electromotive force is small and the charging current I14 is small, so that the period of the oscillating output 17 is large. After starting, the electromotive force becomes large, and the charging current I14 becomes large, so that, the period becomes small. The rate of the periods is compressed and magnified by the characteristics of the diode.
