摘要:
In an optical disk manufacturing method in which a first photo resist layer, an intermediate resin layer, and a second photo resist layer are formed on a substrate in the stated order, a resin solution which is unsoluble in organic solvent is applied to the first photo resist layer, heated, and hardened to form the intermediate resin layer. Thereby the use of a large, expensive device such as a vacuum deposition device or sputting device is eliminated.

An optical information recording medium recordable of the analogue NTSC color video signal under the conditions of a high S/N ratio and a low jitter, and capable of being played by a commercially available LD player. The medium comprises: a transparent substrate on which pre-grooves are formed with a depth of 1450-2050 angstroms; an optical absorbing layer with an absorbance of 0.7-0.9 made of palladium phthalocyanine dye formed on the substrate, the absorbing layer having pits each having a changed reflectivity being duty-cycle modulated in response to a limited waveform which is formed through the steps of: adding at least one of a second FM carrier and a third pulse carrier to a first FM carrier having a first center frequency and a first frequency band, the second FM carrier having a second center frequency lower than the first center frequency and a second frequency band spaced from the first frequency band, the third pulse carrier having a pulse-repetition frequency lower than the second center frequency and a third frequency band spaced from the second frequency band, to form a frequency-division multiplex signal; and symmetrically clipping the multiplex signal to form the limited waveform; and reflecting layer formed on the optical absorbing layer.

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.

A method for assembling an arc-extinguishing chamber of an electromagnetic contactor includes a step of fixing a pair of fixed contacts each including a support conductor and a C-shaped part, to a bottom plate part of the arc-extinguishing chamber having a tub-shape with one end being open, the C-shaped part defining inside of the arc-extinguishing chamber; a step of installing an insulation cover covering a part other than a contact point part of each C-shaped part of the pair of fixed contacts; and a step of disposing a movable contact to be capable of contacting to and separating from the contact point parts of the fixed contacts.

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.

A first parameter correlated with a degree of fluctuation of output from an air-fuel ratio sensor is calculated, and whether or not the calculated first parameter has a value between a predetermined primary determination upper-limit value α1H and a primary determination lower-limit value is determined. Such forced active control as reduces an air-fuel ratio shift in one of the cylinders which is subjected to a most significant air-fuel ratio shift is performed when the calculated first parameter is determined to have a value between the predetermined primary determination upper-limit value and the primary determination lower-limit value. A first parameter is calculated while the forced active control is in execution. The calculated first parameter is compared with a predetermined secondary determination value to determine whether or not variation abnormality is present.

A movable hook portion (13) provided in a unit side coupling surface (2a) of an accessory unit (2) includes a hook portion main body (14), which is formed with a movable claw (23a) and a pressed piece (22), and a straight spring (15), slidably accommodates the hook portion main body (14) in a main body accommodation concave portion (16) formed in the unit side coupling surface (2a), and accommodates the straight spring (15) in a spring accommodation concave portion (17a) formed in the unit side coupling surface (2a) so as to be orthogonal to a sliding direction of the hook portion main body (14), with a middle portion in a length direction of the spring being engaged with the hook portion main body (14). When the hook portion main body (14) is slid in a disengaging direction which brings the movable claw (23a) and a hooking hole (8a) of an electromagnetic contactor (1) into a disengaged state by pressing the pressed piece (24), an elastic restoring force of the straight spring (15) elastically deformed into a bow-like shape acts on the hook portion main body (14) in a direction opposite to the disengaging direction.

An apparatus for detecting a variation abnormality in an air-fuel ratio between cylinders according to the present invention is configured to calculate a value representing a change in an air-fuel ratio based on an output of an air-fuel ratio sensor that is provided in an exhaust passage in a predetermined operating state in which fuel is injected from a fuel injection valve, perform, to the calculated value, sensitivity correction in accordance with a sensitivity of the sensor based on the output of the sensor during fuel-cut operation and outside atmospheric pressure correction based on outside atmospheric pressure, and determine the presence or absence of a variation abnormality in an air-fuel ratio between cylinders by comparing the corrected value with a predetermined value.
