Title: Pneumatic tire for heavy load
Inventor: TANAKA MAKOTO
IPC: B60C11/12
Filed: 1990-08-01
Abstract: PURPOSE:To reduce the generation of tire noise as one-sided wear is prevented from occurring by a method wherein the sipings of adjoining ribs partitioned by a main groove in the peripheral direction of a tire are formed in a manner to be deviated from each other peripherally of a tire, and the length, in the peripheral direction of the tire, of each siping is increased to a value higher than the length, in the direction of the width of the tire, thereof. CONSTITUTION:A tread 12 of a tire 10 is provided with four main grooves 14 separated away from each other in the direction of the width of a tire and extending substantially continuously in the peripheral direction of the tire and five ribs 16 partitioned by the main grooves and extending continuously in the peripheral direction of the tire. Each rib 16 has a plurality of sipings 18 formed at intervals of a specified distance in the peripheral direction of the tire. The siping 18 are formed such that they are deviated from each other in the peripheral direction of the tire between the adjoining ribs 16. A length LP in the peripheral direction of the tire of each of the sipings 18 formed in each rib 16 in a manner to be separated away from each other in the peripheral direction of the tire and a length LW in the direction of the width of the tire are selected so as to satisfy a relation of LP>LW. This constitution prevents the occurrence of one-sided wear and reduces the frequency characteristics of tire noise especially the maximum sound pressure thereof.

Title: On-off device for regulating air current
Inventor: YAMAMOTO MASAO
IPC: F16K31/70
Filed: 1985-09-12
Abstract: PURPOSE:To simplify regulation of an air flow, by providing a shape memory alloy which has the one end mounted to an on-off valve, the other end secured, and exerts rotation moment in a direction reverse to that of rotation moment by a weight on the on-off valve through expansion and contraction. CONSTITUTION:A weight 6 is attached to a bent part 5a of a rotary shaft 5 of a main air current pipe 1 to exert rotation moment thereon. A fixing jig 8 is connected to an on-off plate 7 through a shape memory alloy 9. When the temperature of air is low, an inlet is closed by rotation moment exerted by the weight 6, and when temperature is increased, the shape memory alloy 9 is contracted to exert rotation moment in a direction reverse to that of said rotation moment on the on-off plate 7 to open an inlet. This enables a device to respond to a change in the conditions of an air flow.

Title: Driving of stepping motor
Inventor: MATSUMOTO KENJI
IPC: H02P8/00
Filed: 1993-08-17
Abstract: PURPOSE:To eliminate the setting of a torque margin by a method V wherein a motor is operated as a normal stepping motor when there is no step-out and when there is a step-out, the motor is operated as a DC motor and a command position is traced with the maximum torque and after that the motor is returned to a normal operation as a stepping motor. CONSTITUTION:A counter 3 takes in a position command pulse and outputs a count command position thetacmd signal. A memory 6 reads out an excitation angle of lag thetalag to correspond to the preliminarily stored rotor speed thetarot from a counter 4. An adder and subtractor 7 calculates a formula I wherein the command position thetacmd, the rotor position thetarot, and the excitation angle of lag thetalag are added or subtracted. A signal from the adder and subtractor 7 is compared with + or -pi/2N by a comparator 10. When there is no step-out as shown by a formula II, an excitation command position thetaex output from a data selector 11 is set the same as the command position thetacmd. When there is a step-out as shown by a formula III, a formula IV is used instead, that is, the command position is traced and returned to the synchronous position and then is reset to the original stepping motor mode.
