Title: Tread cutting device and pneumatic tire manufactured using the device
Inventor: TERAJIMA MASATOSHI
IPC: B60C11/00
Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To prevent the physical property performance of rubber of a tread joint face from being deteriorated without the necessity to heat a cutter for friction reduction by making the part of a circular rotary cutter blade thickner than a holder other than the blade. SOLUTION: The thickness (gauge) A of the blade part 2 of a circular rotary cutter 1 for the tread cutting device is set to be larger than the thickness B of a holder part 3 so that the relationship A>B is established. That is, the blade part 2 is thick enough by alternately projecting blades 2 to the right and the left like saw teeth. Consequently the frictional force to be caused by the contact between the cut face of a tread member and the holder part 3 is low, so that the tread member can be cut smoothly without the necessity to heat the rotary cutter 1 during cutting. Consequently, the physical property performance of rubber of a tread joint face is not deteriorated and therefore a pneumatic tire with a highly wear-resistant tread is obtained.

Title: Laser oscillator
Inventor: KARUBE NORIO
IPC: H01S3/081
Filed: 1988-01-08
Abstract: PURPOSE:To eliminate the need for components for obtaining special circularly polarized light by constituting a laser oscillator so that emitted light is changed directly into circularly polarized light. CONSTITUTION:A rear mirror 10 has a particularly high reflectivity in the direction of the arrow 10a, and turning-around mirrors 11 and 12 are used as a phase retarder in pi/2 by a pair of two. A laser oscillator oscillates by linearly polarized light in the direction that it is turned by pi/4 from a plane formed by optical axes 7a-7c, as shown by the arrow 10a or 10b in the region of the optical axis 7a. The laser oscillator oscillates in a state of circularly polarized light in the region 7c, and oscillation in the state of complex polarized light having the state of different polarization light according to the positions is generated. Consequently, since the rear mirror 10 has the maximum reflectivity in the direction that it has a constant inclination, linearly polarized light is acquired between the rear mirror 10 and the turning-around mirrors 11, 12 at the shortest distances from the mirror 10, the turning-around mirrors 11, 12 function as a phase retarder, and phase is shifted only by pi/2, thus obtaining circularly polarized light beams as emitted beams acquired.

Title: Ecl compatible output circuit
Inventor: NAGASHIMA KUNIO
IPC: H03K19/094
Filed: 1986-01-09
Abstract: PURPOSE:To reduce the fluctuation of an output voltage with respect to the variation of an input voltage and a threshold voltage by using a source resistor in place of a constant current source using a FET and always allowing a constant current to flow to a load resistor of the FET whose gate receives a reference voltage so as to apply an output voltage level shift. CONSTITUTION:The titled output consists of normally-on type MESFETs 100, 204, 206, a source resistor 300 and a load resistor 200. When the input voltage is a reference voltage Vref or over, a current I2 flows to the FET 204 only by the input voltage. A constant current I0 decided by the FET 100 flows to the load resistor 200 in this case and a high level output voltage is obtained. When the input voltage is the voltage Vref, the sum of the current I0 flowing to the FET 100 and the current Ic flowing to the source resistor 300 flows to the load resistor 200 and the output voltage goes to a low level. Thus, the fluctuation of the output level to the variation of the threshold value VT is less. Moreover, the high level output is decided in the output circuit independently of the current I2 flowing to the FET 204 and the effect of the input voltage is not given.
