Title: Pneumatic tire
Inventor: BERUNTO REEBENHAUPUTO
IPC: B60C9/20
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To lower manufacturing cost by having a belt layer composed of a non-metal cord and having a belt cover layer arranged with a heat contractibility cord on its right and left shoulder areas, respectively, enveloping the side ends of the belt layer in the tire axial direction. SOLUTION: Movement produced at belt ply side ends 15, 16 covering a belt layer 4 during high speed rotation of a tire can be regulated so that separation of the belt layer 4 and such other damages may not show on the tire by suitably selecting a heat contractibility material for a thread of a cord on belt cover layers 9, 10 of both shoulder areas 8, 8. Centrifugal force working on belt ply side ends 15, 16 corresponds to the heat contraction force by a belt cover layer 5 on both shoulder areas 8, 8. Since the belt layer 4 does not require compression rigidity for such reasons, a thread or a cord of non-metal material can be used and thus lightening of weight of a tire provided with a steel cord is possible.

Title: Electronic musical instrument
Inventor: MATSUNAGA IKU
IPC: G10H7/02
Filed: 1995-04-28
Abstract: PURPOSE: To obtain an electronic musical instrument, without requiring a special function controllable not to cause errors between loop readings, by presetting waveforms so that results are always made coincide at every time in the leading part of the repeated readings at the time of decoding. CONSTITUTION: The data stored in a delay register 22 are read, added with the data difference value, which are transmitted from a quantization control width block 21, by an adder 23 and decoded. The data values of the musical sound waveforms, to which difference values are added in the decoding process and generated, are stored in the register 22 and a preparation for a next data process is executed. The musical sound waveforms, which are processed and decoded, are set so that they always return to a certain delay register value when the waveform data generation returns to the loop top. Therefore, the device which resets a new value when the process returns to the loop top and the process for controlling waveforms by using a prediction filter coefficient that are designed so as to always obtain a constant value are unnecessitated.  Thus, an electronic musical instrument simple in its construction and low in cost, is obtained.

Title: Radio communication equipment
Inventor: UI TAKASHI
IPC: H04B1/40
Filed: 1995-05-26
Abstract: PURPOSE: To enhance the effect with stable frequency over a wide temperature range by changing a reactance of a crystal vibrator based on a frequency correction signal outputted from a control circuit to inversely correct the mean value of the frequency temperature characteristic. CONSTITUTION: An ambient temperature of the radio communication equipment 11 is detected by a temperature detection circuit 73 and a voltage generated across a thermister is monitored by a control circuit 3. When ambient temperature decreases below to a temperature compensation range of a crystal oscillator 71, it is detected by the circuit 3. Then the circuit 3 reads a frequency correction signal used to inversely correct a frequency temperature characteristic of the crystal vibrator from a storage circuit 74 by using a voltage outputted from the circuit 73 as an address point and converts the signal into a voltage, which is fed to a variable capacitor in a frequency correction circuit 72 to change the capacitance. Thus, the frequency temperature characteristic of the crystal vibrator is inversely corrected to correct the oscillating frequency of the oscillator 71.  Even when the temperature decreases, the temperature characteristic changes properly to allow the oscillator 71 to oscillate a prescribed frequency.

Filed: 1987-05-27
Abstract: PURPOSE:To simplify the function of a semiconductor circuit, by using a power source having a fixed potential difference to a discharge potential. CONSTITUTION:A power source is set to a voltage which is lower than the low level (nonselected level) of a discharging circuit part, for example, word lines UW and LW by fixed potential as the power source of the emitter resistance of a current source transistor Q12. Therefore, even when a power supply circuit which is simple in design is used, such troubles that a large current is always made to flow to a nonselected discharge circuit and the discharge current of a selected discharge circuit becomes smaller than a designed one can be avoided. Accordingly, the discharge circuit can be made simpler.

Filed: 1986-06-04
Abstract: PURPOSE:To prevent the corrosion of reinforcing bars buried in a concrete structure by salt by burying an insoluble electrode in the concrete structure and supplying electric current for electrolytic protection between the electrode as the anode and the reinforcing bars as the cathode. CONSTITUTION:An insoluble electrode 3 of magnetic iron oxide, silicon cast iron, a lead-silver alloy, platinum plated titanium or the like is buried in reinforced concrete 2. DC voltage from a power source 4 is applied between the electrode 3 as the anode and the reinforcing bars 1 as the cathode to supply anticorrosive current. Since the electrode 3 is insoluble, the metal does not enter the concrete by leaching. Since the reinforcing bars 1 act as the cathode, a corrosion cell is not formed even when chlorine ions and air are present around the rods 1.

Filed: 1984-06-20
Abstract: PURPOSE:To stabilize an oscillation output by giving a histeresis so as to eliminate chattering in applying digital encoding to temperature information. CONSTITUTION:An output voltage VA of a temperature detecting circuit 11 is inputted to a voltage shift circuit 13 in a temperature encoding circuit 12 and fed to a terminal A of a changeover switch 14. The voltage shift circuit 13 has a function shifting the inputted voltage VA by a prescribed minute quantity and its output voltage VB is fed to the other terminal B of the changeover switch 14. The switch 14 changes over the VA and VB alternately and gives them to an A/D coverting circuit 15 and a discriminating circuit 16. The discriminating circuit 16 compares a digital code corresponding to the VA with a digital code corresponding to the VB and when the both are coincident, the digital code is regarded as the temperature information at that point of time. The temperature information is inputted to a processing circuit 21 and used for the control of the oscillating frequency of the crystal oscillation circuit.

Title: Thickener for sludge
Inventor: KOJIMA KENJI
IPC: C02F1/24
Filed: 1980-09-16
Abstract: PURPOSE: To perform the efficient rising of sludge and to enhance the concentration of solid matter in concentrated sludge, by reducing the cross sectional area of the middle stage part of a floating vessel so as to raise an internal stress on an accumulated sludge layer.  
     CONSTITUTION: When sludge mixed with pressurized water is fed into a floating vessel 1 through its bottom, dissolved gas in the pressurized water turns into fine bubbles and adheres to the sludge. The sludge, affected with buoyancy, rises inside the vessel 1, reaches the water surface 7 and forms an accumulated sludge layer 8. In this case, a projecting part 2 is formed at nearly the central stage of the vessel 1 and slightly above the water surface 7, so that internal stresses in the accumulated sludge layer 8 and an underwater sludge layer 9 increase and that each sludge concentration becomes high. Consequently, the concentration of solid matter in concentrated sludge taken out through a discharge hole 6 is enhanced at 6W7% or so.
