Title: Measuring method for flow velocity
Inventor: JINDA AKIHITO
IPC: G01F1/696
Filed: 1986-03-31
Abstract: PURPOSE:To save the consumption of power by measuring flow velocity by using a pulse signal in a transient state up to the stabilization of the temperature of a heating resistor. CONSTITUTION:The pulse signal is passed through a constant current circuit and converted into a large current, which is supplied to a temperature resistor 7 for flow velocity measurement which is made of a thin platinum film, so that the resistor 7 heats up. For example, even when the resistance bulb 7 for flow velocity measurement heats up in case of an increase in the flow velocity, more heat is conducted to fluid, so the rise in the temperature of the resistance bulb 7 becomes gentle and the time when a reference voltage is arrived is delayed. Consequently, the number of times of the rise of the output signal of an AND gate 10 to an H level decreases. Therefore, there is a constant correlation between the flow velocity and the number of times of the rise of the signal of the AND gate 10 to the H level and the number of times is counted to measure the flow velocity.

Title: Ram material cutting method and its device
Inventor: TATSUMI SHIGERU
IPC: B29C47/08
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To improve the precision of a cut surface wile preventing the cut surface from tilting, and in addition, suppress the increase of a filling factor by a method wherein a rotary blade after cutting a raw material by the rotation, is temporarily stopped, and the rotary blade is rotated again after a specified period of time so that an intermittent rotation may be performed. SOLUTION: A workpiece which has passed through a discharging nozzle 33 is cut into a specified dimension by a rotary blade 61 which is intermittently rotate-driven at a high speed. In this case, even if a workpiece is not sufficiently hardened, a cutting section can be cut at a high precision. In addition, a shape retaining property is high. Also, the cutting section is prevented from sagging due to the cooling of the outer peripheral part. Therefore, the dimensional precision is drastically improved, and for this reason, when a bag packing is performed, the filling factor is increased. Also, the rotary blade 61 temporarily stops after rotating once at a high speed, and a fixed dimension of a melt is prevented from becoming shorter, and a handing after that is facilitated, and the increase of the filling factor can be suppressed.

Abstract: PURPOSE:To supply constant tube current independently of voltage variation of commercial power source by previously setting reference voltage with a reference voltage setting circuit to supply preferable tube current. CONSTITUTION:Tube current is detected with a rectifier circuit 4 which is connected to a secondary junction of a high voltage transformer 1.

Reference voltage b is set by adjusting an adjusting device, or a resistor, of a reference voltage setting circuit 6 which is kept constant voltage by Zener diode 5, and inputted to other input terminal of the error amplifier 7. Pulse amplitude of a pulse-amplitude control oscillating circuit 8 is varied by output potential of the error amplifier 7, and pulse wave height is varied by transistor circuits 11 and 12. Thereby pulse amplitude and pulse voltage obtained from the secondary side of a transformer 9 are varied. The valied output pulse is smoothed by a smoothing circuit 13, and resulting d.c. voltage is applied to a base of a control transistor 17. Therefore, voltage across a bridge circuit 16 which is connected to the primary side of filament of the high voltage transformer is controlled.

Filed: 1985-04-12
Abstract: PURPOSE:To simplify the circuit constitution by changing over an antenna to other antenna being at a higher level when a reception signal level of the former antenna is a set value or below and performing no changeover when the signal level is the setting value or over. CONSTITUTION:A comparison circuit 10 compares a reception level signal A with each voltage level of a reference voltage signal G, generates an output signal B in response to the level and outputs the signal to a changeover pulse control circuit 14 for antenna changeover. When the reception level is lower than the reference voltage VS1, the control circuit 14 outputs an antenna changeover signal E and when the level is the voltage VS1 or over, the circuit 14 gives no changeover signal. When the reception level of antennas F1, F2 is both lower than the reference voltage VS1, the antennas are changed over with a prescribed interval to select an antenna with a higher reception level. A voltage reduction circuit 16 attenuates the reference voltage G for a prescribed period when the control circuit 14 outputs the 1st changeover pulse and when the reception level of the changed-over antenna is lower than the level before the changeover, the control circuit 14 changes over again the changed-over antenna to the original antenna.
