Title: Reflection type optical type encoder apparatus
Inventor: NAKAMURA NOBUAKI
IPC: G01D5/30
Filed: 1988-11-28
Abstract: PURPOSE:To enable detection of two signals with phases A and B (with a phase difference of 90 deg. in angle of electricity) by specifying a pitch of a light spot of three beams from a laser reader. CONSTITUTION:An encoder track 2 is formed on a rotary encoder plate 1 responsive to rotation of a test specimen with a specified number of pids 3 arranged at an equal interval. Then, changes in intensity of reflected light to a laser light beam to the track 2 is converted into an electrical signal and read with a laser reader 7 to detect rotation and a position of the test specimen. Here, pids 3 of the track and the interval thereof are set at an equal length l so that they are adjusted to be irradiated with three light spots 16A, 16F and 16B with a specified diameter of the three beams by the device 7. A pitch between the light spots 16A, 16F and 16B is given by P={(1.5+n)/2} (n: integer of 1 or more). Two signals of phases A and B can be detected by the spots 16A and 16B on both sides.

Filed: 1994-11-10
Abstract: PURPOSE: To flexibly cope with a utilization state by comparing the throughput of a decentralized processing system with a necessary throughput and requesting a necessary resource quantity, and suppressing a resource quantity allocated to a processing module within a resource use value range. CONSTITUTION: The decentralized processing system 104 which provides information information services is constituted as a decentralized application on a network 101, and processing modules 105 have a mutual communication means and operate by utilizing a network resource 108 such as a processor 106 managed by a node 102. Here, each processing module 105 compares the current throughput value with the specific threshold value, calculates a resource quantity that can maintain the threshold value when the through put is less than the threshold value, and sends a new resource allocation request to the node 102. Then the resource use state information of the node 102 is compared with the new resource allocation request quantity to calculate a new resource allocation quantity, and it is judged whether the calculated quantity is allowed.  Consequently, the maintenance of the requested performance and the effective utilization of resources by load smoothing are both satisfied.

Title: Steering control wheel control structure
Inventor: SHIMIZU YASUO
IPC: B62D137/00
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To improve the small turn performance, maneuverability and steering feeling, etc., of a vehicle. SOLUTION: Front wheels 6 are driven by an electric steering device in which a rack shaft 8 is driven by an electrical motor 9. In such a vehicle, the front wheels are supported by a multilinkage suspension composed of an upper arm 21 and a lower arm 22, with a caster trail being substantially zero, a king pin angle being substantially zero. Additional steering torque in proportional to a steering angle sensed by a steering angle sensor 11 is added to control characteristics causing no output of electric motor driving signal at a neutral position of a steering. The electric motor driving signal is thus obtained. When the steering angle is sensed, the additional steering torque is added. The front wheels are controlled based on the electric motor driving signal according to the added steering torque. It is thus possible to improve steering repulsion near the neutral position of the steering, secure stability in straight running, generate resetting force according to steering angle and obtain returning of the steering.

Title: Method and device for surface treatment
Inventor: MIYAGAWA TAKUYA
IPC: H01L21/3065
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a surface treatment method and device which can modify the surface of a body to be treated with less plasma damage and has a large degree of freedom for the installation location of the body to be treated. SOLUTION: For increasing the wetting property of a soldering part 12 of a work 10, a feed gas containing such halogen compound as CF4 is introduced into a plasma generation part within a surface treatment unit 30. At this time, the feed gas may be sent by a carrier gas excluding He. The feed gas is excited and dissolved by an electrode where an AC voltage with a low frequency of 0-50kHz or a DC voltage, is imposed thus generate fluorine F2 with a high reactivity. By bringing a treatment gas containing the fluorine F2 into contact with the work 10, the work 10 is subjected to surface treatment. At this time, since fluorine radical with a short life is not treated as a main body, the position of the work 10 can be freely set. When using air as a carrier gas, the air is mixed after dissolving the feed gas, thus suppressing the generation of ozone.  By decomposing the halogen compound in an atmosphere containing water, hydrogen halide can be dissolved efficiently.
