Title: Automatic equalizer
Inventor: MIZOGUCHI SHOICHI
IPC: H03H17/00
Filed: 1991-02-27
Abstract: PURPOSE:To equalize interference due to a fading in which a reflecting wave is stronger than a direct wave resulting from insufficient equalization by connecting an adaptive matching filter making an impulse response symmetrical before a decision feedback equalizer. CONSTITUTION:A base band signal sampled and quantized by an A/D converter 12 is inputted to a transversal filter 103 whose elements are arranged at an interval of T/2. A tap coefficient of the transversal filter 103 is controlled adaptively by a tap coefficient control signal generating circuit 104 so that the impulse response of a transmission line at the output is made symmetrical. Thus, even distortion due to fading is equalized in the case of rho>1 (rho is a ratio of amplitude of reflection wave/amplitude of main wave) in which a reflection wave, that is, a delay wave resulting from insufficient equalization by a decision feedback equalizer 301 at a post-stage is stronger than a direct wave.

Title: Signal converting device
Inventor: FUTAGAMI ISAO
IPC: G01D3/02
Filed: 1992-02-21
Abstract: PURPOSE:To improve the accuracy and stability by performing moving average when a pump is operated and to secure a quick responding property by not performing the moving average when the pump is stopped. CONSTITUTION:A counter circuit 2 counts pulse inputs P1. Of the count values of the circuit 2, those obtained at regular periods are outputted from an output point AO as F/V-converted values after the count values are held in a hold circuit by means of a synchronous signal generating section 1 and subjected to moving average at a moving average section 4. However, when the pump is stopped, a contact signal DI is turned on or a signal discriminating section 5 discriminates that the held value of the circuit 3 becomes smaller than a prescribed value and, in both cases, the output of an OR circuit 6 is turned on. The output of the circuit 6 controls a switching section 7 and, as a result, the output of the circuit 3 is adopted to the output point AO instead of the output of the section 4 and the moving average function is deleted.

Title: Quantitative dispenser for water
Inventor: MORIWAKI TOORU
IPC: E02B7/20
Filed: 1981-03-10
Abstract: PURPOSE:To keep the amount of water to be flowed from a trunk waterway to  branched waterways almost constant by using a system in which a water conduit is  extended into a static water tank, a valve body is inserted into the longitudinal  through hole of the wall of the extended conduit in a vertically movable manner, and  the valve body is connected to a float inside the static water tank. CONSTITUTION:Water sent through a water conduit 4 from a trunk waterway 1 flows  from the V-shaped opening of a valve body 7 into the valve body 7, enters a static  water tank 3, overflows cross an overflow dam 5, and goes into a branched waterway  2. When the level of water in the waterway 1 rises, the level of water in the static water tank 3 is also raised, a float 10 goes up, the valve body 7 is raised through a  lever 13 to narrow the opening 9, and thereby the amount of incoming water is controlled. Since the valve body 7 contacts with water on the trunk waterway side only  by its outside vertical and cylindrical face, the valve body 7 undergoes no buoyance from the water of the trunk waterway. On the other hand, since buoyance to the valve  body 7 from the water of the static water tank 3 is constant, loading on the float 10  becomes constant and thereby the amount of water to be released from the trunk  waterway to the branched waterway can be kept constant.

Filed: 1980-03-17
Abstract: PURPOSE: To restrict the amount of formed martensite to lower than the limited value, and to improve the fatigue life, by specifying the Ni-equivalent of the material, the working temperature and the working rate, at drawing the austenitic stainless steel wire.  
     CONSTITUTION: The material of austenitic stainless steel containing Ni-equivalent ranging 20W26% is repeatedly drawn into wire, and the final annealing is applied to this wire. Next, this wire is drawn at the area reduction 60W90% while being heated to 60°C or higher. Hereby, the amount of formed strain-induced martensite is restricted to 30% or less, and the increase of martensite at the fatigue limit is increased. Besides, the reason of restriction of the condition is as follows; with respect to Ni-equivalent of the limited range is the optimum value from the point of the wire drawing temperature and the amount of the formed martensite. With respect to the wire drawing temperature, the practical 250°C or lower temperature develops satisfactory effect. Furthermore, with respect to the working rate of the wire drawing work, above specified range is the limit permissible in obtaining the practical tensile strength and the smooth surface.

IPC: B65D83/14
Filed: 1995-01-31
Abstract: PURPOSE: To keep a flow rate-regulating, member from being unnecessarily dislocated under impetus of the contents and regulate the flow rate properly by providing a guiding projection and a directional flow regulator for forcedly diverting the flow of the contents both on the upstream side of the flow rate- regulating member. CONSTITUTION: In an aerosol bomb closing of a gap 12 caused by movement of a flow rate-regulating member 11 that accompanies handling of a press button 7 is alternated repetitively with opening of the gap 12 resulting from a subsequent decrease in pressure at a receiving part 11a that resets it. In this instance on the upstream side of a stepped part 11b of the flow rate- regulating member 11 a tapering guiding projection 11c which comes in contact with the peripheral surface of an inside space 8 is formed. In the inside space 8 a directional flow regulator 15 is formed at a position upstream from the flow rate-regulating member 11 and a little downstream from a stem 4, by means of which the matter for spraying brought through the stem 4 is turned in direction by about 90 degrees before being sent to the flow rate-regulating member 11.
