Title: Pneumatic radial tire
Inventor: KAWABATA MISAO
IPC: B60C11/00
Filed: 1989-12-22
Abstract: PURPOSE:To improve the extremely high speed running performance of an extremely high speed flat radial tire for an automobile by inclining the groove wall of a peripheral groove in a direction where a groove width increases gradually, and making the inclining angle of a one groove wall larger than that of the other one, and inclining the groove wall from a position higher than a groove bottom and on the side of the groove bottom so as to gradually increase the groove width. CONSTITUTION:A one groove 7b of a peripheral groove 1a arranged to the outside of a vehicle in mounting a tire on it is inclined in a direction where a groove width increases gradually from a groove bottom toward a tread surface. The other groove 7a is inclined from an outside position P in the radial direction of a tire at an inclining angle alpha larger than that beta of the groove wall 7b in the direction of gradually enlarging groove width. In addition to that, the groove 7a is inclined at an inclining angle deltafrom the position P toward the groove bottom in the direction of the gradually enlarging groove width. In this case, a distance h of the position P from the groove bottom is established to be 0.15-0.4 times as long as a groove depth H. This formation can improve the operational safety of an automobile during its high speed running and prevent the partial wear of the tire during high speed turn-running.

IPC: B60B21/10
Filed: 1991-11-19
Abstract: PURPOSE:To prevent the dislocation of a rim-assembled tire from a rim during travelling of a vehicle without increasing fitting force when a tire is assebled on the rim while maintaining the efficiency of rimassembling operation by providing slip-preventing areas consisting of plural step parts, the height and pitch of which are restricted and which are arranged in parallel, on the bead seat face. CONSTITUTION:Slip-preventing areas 12 in which step parts 11 which are extended in the direction of the tire-axis over the almost full width of a bead seat face, and the step-height of which is 0.3mm to 0.8mm, are provided at 1.0mm to 5.Omm pitche in parallel in the peripheral direction of a tire, are provided on the bead seat face 10 on which the bead bottom face 9 of a bead part 3 in the range of at least 30% of the peripheral length of the bead seat face. As a result, when the bead part is fitted on the bead seat face, the step parts deform the bead bottom face, and the bead bottom face is engagingly locked in the peripheral direction of the tire. By assembling the tire on the tire-rim formed in this way, the slip of the pneumatic tire is prevented, and the dislocation of the tire from the rim can be prevented.

Title: Automatic gain control circuit
Inventor: TAKAYOSHI SHUICHI
IPC: H03G3/10
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To improve the linearity of a gain curve. SOLUTION: A differential pair of transistors Q9 and Q10 which are provided in a buffer circuit decrease in accordance with the increase in base currents Ib2 and Ib1 of two sets of differential pair of amplifiers of a variable gain amplifier circuit, and produce collector currents I2 and I1 respectively which increase in response to the reduction. Each of the currents I2 and I1 is respectively supplied from emitter currents of two transistors Q8 and Q7 of an emitter follower that is provided in the buffer circuit. By so doing, even if the currents Ib2 and Ib1 of two sets of differential pair of amplifiers of the variable gain amplifier circuit are increased or decreased, the difference of each emitter current value of the transistors Q8 and Q7 of the buffer circuit is reduced.  Then, the difference between each base-emitter voltage of the transistors Q8 and Q7 of the buffer circuit is eliminated and the linearity of a gain curve is improved.

Title: Semiconductor memory tester
Inventor: BABA TADAHIKO
IPC: G11C17/00
Filed: 1993-12-27
Abstract: PURPOSE:To shorten the processing time of a semiconductor memory tester by connecting the output of an address de-scrambling calculating section to one input of a multiplexer and the output of a base calculating section to the other input of the multiplexer and outputting the outputs of the calculating sections by switching by setting a skipping mode. CONSTITUTION:Ordinary tests are performed by switching the multiplexer 6 used for the test to an upper multiplexer and writing and erasing tests on a flash memory are performed by switching the multiplexer 6 to a lower multiplexer by using a skipping mode signal and by-passing a destination calculating section and address de-scrambling calculating section. Namely, the tests are performed by performing calculation only for the N stages of a base calculating section by skipping the calculation for M stages of the destination calculating section and for L stages of the address de-scrambling calculating section while the number of pipeline stages for generating addresses is (N+M+L) which is the sum of the stages of the base calculating section, destination calculating section, and address de-scrambling calculating section. Thus the time of the preceding processing is shortened.

Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To supply extremum value voltage by an output without offset by holding the current of a bipolar transistor(TR), capable of receiving input voltage by its base and supplying an extremal value voltage from its emitter and connected to a common voltage at a steady value. SOLUTION: A TR Q10 receives an input voltage V1 to its base, connects its collector to a high power supply voltage Vcc and connects its emitter to a line Vmax common to all cells of the circuit. The line Vmax supplies an extremum value voltage to be maximum voltage. The voltage V1 is supplied to the emitter of an NPNTR Q11 connecting its base and collector to the TR Q10 in parallel, and the emitter is connected to ground GND through a current source 20 drawing a current 10. When the voltage V1 is lower than other input voltage, a TR Q12 in a differential stage receives a voltage lower than the base voltage Vmax of a TR Q13 to its base and the differential stage is imbalanced. Then the entire current to the current source 22 is allowed to flow into the TR Q13, and the differential stage Q12, Q13 can avoid the supply of a current to the common line Vmax .
