A core layer has a light entrance region and a light exit region, said light entrance region having a width greater than said light exit region. The light entrance region has at least a side surface shaped as a reflecting surface. The light entrance region has an end having a parabolic shape. An LED is disposed in contact with a lower surface of the light entrance region. Signal light is introduced from the LED into the light entrance region with increased light entrance efficiency, and is highly efficiently reflected by the side surface of the light entrance region for higher light collecting efficiency.

An optical waveguide module provides light intensity detection is comprised of a light emitting portion, a substrate and a clad formed over the substrate wherein a first core and a second core are covered with the clad, the first and second cores being formed of a material having a higher refractive index than that of the clad. A first reflection surface is formed at an incident side end portion of the first core for reflecting light emitted from a light emitting portion in the guiding direction of the first core and a second reflection surface is formed as an incident side end portion of the second core for reflecting light emitted from the light emitting portion in the guiding direction of the second core. A light receiving portion receives and detects an amount of light in order to control the intensity of the emitted light.

To provide an optical waveguide and an optical transmitting and receiving module able to perform a transmitting operation and a receiving operation simultaneously, wherein a linearly first waveguide 21 that one side is coupled to an optical fiber 3 and the other side is coupled to a light receiving element 4, and a second waveguide 22 that one side is coupled so as to make an acute angle θ with the side of the first waveguide 21 to be coupled to the light receiving element 4 and the other is coupled to a light emitting element 5 are provided. By controlling a shape of the second waveguide 22, the receiving signal light from the optical fiber 3 is received to the light receiving element 4, and is not guided to the second waveguide 22. Therefore, the receiving operation and the transmitting operation can be preformed at the same time. Namely, when the transmitting optical signal is the incident of light from the light emitting element 5 to the second waveguide 22, the optical signal is guided by the second waveguide 22 toward the first waveguide 21, coupled to the first waveguide 21, and guided toward the optical fiber 3.

An optical transmitting and receiving module for an optical waveguide performs both a transmitting operation and a receiving operation simultaneously. The linear first waveguide is provided such that one side is coupled to an optical fiber and the other side is coupled to a light receiving element. A second waveguide is coupled so as to meet and make an acute angle with the first waveguide. The second waveguide is shaped with a tapered portion adjacent to the first waveguide.

A first parameter correlated with a degree of a variation in the output from the air-fuel ratio sensor is calculated. A possible range of a second parameter representing a degree of a variation in air-fuel ratio among the cylinders is determined based on the first parameter. The first parameter is calculated with an air-fuel ratio of a predetermined cylinder forcibly changed. A difference between the unchanged first parameter and the forcibly changed first parameter is determined. A first characteristic representing a relation between the second parameter and the difference is determined based on the possible range of the second parameter and the difference. One of the determination value and the first parameter calculated before the forced change is corrected based on inclination of the determined first characteristic.

The game control device may include a storage unit, a first match-up executing unit, a character ability updating unit, and a second match-up executing unit. The storage unit stores an ability value of each player character. The first match-up executing unit executes a first match-up between two player characters in response to input of a communication terminal, and to determine a result of the first match-up based on the stored ability value of each player character. The character ability updating unit updates, based on the result of the first match-up, the ability values of the two player characters, and causes the storage unit to store the updated ability values. The second match-up executing unit executes a second match-up between player characters independently from the first match-up without input of the communication terminal, and determines a result of the second match-up based on the stored ability value of each player character.

Embodiments of the invention provide an actuator head suspension assembly having an efficient voice coil. In one embodiment, a voice coil is formed in a circular or any other shape than the conventional sectorial shape to increase the efficiency of the voice coil and diminish oscillation and noise of an actuator head suspension assembly. The voice coil shape is selected such that the proportion of an out-of-plane force becomes smaller than that in the conventional sectorial voice coil and the proportion contributing as weight to the oscillation energy also becomes smaller.
