Title: Intake quantity control device for lean-burn engine
Inventor: ITOYAMA HIROYUKI
IPC: F02D41/14
Filed: 1994-08-10
Abstract: PURPOSE:To accurately prevent the torque reduction regardless of the operating conditions at the time of switching to the lean air-fuel ratio by setting the increase rate of the intake air quantity when a lean-burn engine is switched to the lean air-fuel ratio larger at the time of low-load low-rotation and smaller at the time of high-load high-rotation. CONSTITUTION:An air-fuel ratio switching means 101 switches the target air-fuel ratio between the vicinity of the theoretical air-fuel ratio and the lean air-fuel ratio on the leaner side, and a fuel feed quantity calculating means 103 calculates the fuel feed quantity based on the air-fuel ratio at that time and the actual intake air quantity and controls a fuel feeding means 104. When the vicinity of the theoretical air-fuel ratio is switched to the lean air-fuel ratio, an intake air quantity increasing means 107 increases the intake air quantity to suppress the torque fluctuation. An increase rate correcting means 108 corrects the increase rate of the intake air quantity large when the revolving speed is low and corrects it low when the revolving speed is high based on the outputs of an engine load detecting means 105 and an engine revolving speed detecting means 106.

Title: Magnetic disk driving device
Inventor: MAEKAWA NOBUKI
IPC: G11B17/028
Filed: 1991-07-29
Abstract: PURPOSE:To prevent an occurrence of a magnetic disk flapping and to obtain a stable rotation by providing a lever which supports a driving pin and a spring which energize the lever in the direction normal to the motor axis so that the lever freely rocks. CONSTITUTION:When a motor axis 105 rotates, a spindle hub 108 rotates because a disk 104 is in its standing still condition because of the clamping force of a head. And a roller 106 is pushed out by a spring 113 at the position where the driving roller 106 coincides with an insertion hole 103a of a center hub 103 and the roller is inserted to the hole 103a. Moreover, when the rotation of the axis 105 continues, the roller 106 rolls while contacting the hole 103a, a lever 111 rotates centered around a pin 112, transmits the rotational force of the axis 105 to the hub 103 and the disk rotates. Since the roller 106 is supported to the hub 108 by the rigid body pin 112 through the rigid body lever 111, the disk 104 is firmly fixed on the hub 108. By this arrangement, the flapping due to the floating disk is eliminated and the reliability of recording and reproducing is improved.

Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device, which has good high-frequency characteristics, such as the maximum cut-off frequency characteristics or the maximum oscillation frequency characteristics, while maintaining the stable breakdown strength of a drain, and a method of manufacturing the device. SOLUTION: A channel layer 122, which is constituted of an N-type GaAs layer, and a semiconductor layer 124, which is constituted of an N<+> GaAs layer, are formed on a GaAs substrate 120 via a buffer layer 121. After source and drain electrodes 129 and 130 are formed, one part of the layer 124 between the electrodes 129 and 130 is converted into an insulator by RIE. One part of this layer 132 converted into the insulator is removed by a wet etching and a gate electrode 133 is formed in the removed part of the layer 132.  As a result, the structure between the electrode 133 and a semiconductor layer 124a under the lower part of the electrode 129 and the structure between the electrode 133 and a semiconductor layer 124b under the lower part of the electrode 130 are respectively formed into a structure, wherein an air space part and a layer 132a converted into an insulator are interposed between the electrode 133 and the layer 124a, and a structure, wherein an air space part and a layer 132b converted into an insulator are interposed between the electrode 133 and the layer 124b. Thereby, a gate-drain capacity is significantly decreased and the high- frequency characteristics of a semiconductor device are improved.

Title: Clutch disk
Inventor: FUKUDA SHIYOUJI
IPC: F16D13/64
Filed: 1980-12-29
Abstract: PURPOSE: To prevent impact vibration and noise by regulating increase of torsion torque and relative torsion angle between a plate and hub appropriately adjusting the shape of an elastic body and size of a recess on the hub.  
     CONSTITUTION: The distance between the axis of a hub 4 and a contact point of an elastic body 9 and a recess 7 increases as a plate 1 revolves. The increase of the distance works as a resistance between the plate 1 and the hub 4 causing the both 1 and 4 to revolve in the same direction, deforming the elastic body 9 corresponding to the increase of the distance. This allows movement of the hub 4 toward the circumference rapidly and steplessly increasing the revolution frequency of the hub 4 in relation to torsion angle.

Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To enable a semiconductor array to be used and improved in yield, even if channels defective in characteristics are present by a method wherein only odd-numbered channels are used to output parallel light signals when only even-numbered channels are detective in characteristics. SOLUTION: The fiber space of a single-mode fiber array used in a parallel light transmission system is 250 μm long, so that the channel space of a semiconductor laser array is half as long as the fiber space.

Semiconductor lasers adjacent to the semiconductor laser are made to serve successively as a first channel, a second channel..., and a semiconductor laser 102 located at the other edge of the laser array serves as a twenty-fourth channel. When only the odd numbered channels are defective and even-numbered channels are all non-defective, only the even-numbered channels are used, and 12 channels are capable of outputting parallel light signals, so that a semiconductor laser array can be improved twice or above as much as the normal in yield.
