Title: Method for evaluating clv drive decision of spindle motor or slider in optical disk master disk exposure device, drive control method and its device
Inventor: WATABE TOSHIO
IPC: G11B7/26
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To precisely evaluate in real-time a positional relation between respective sectors of a CLV format obtained by ideal CLV(constant linear velocity) drive of a spindle motor. SOLUTION: A line length difference between adjacent tracks is fixed always in an equal pitched spiral track formed by the CLV drive, and the line length difference between adjacent segments of an optional length is fixed also, always and similarly. In the case of moving on the track line at the CLV, a fixed phase difference in an answering optional periodic length counter is increased, and a required time at every segment is increased a fixed time each also. The increase of the fixed time corresponds to that a phase difference is increased at a fixed ratio when the count value of the optional periodic length counter is made the phase data. A difference between such a phase difference data and the phase difference data (calculated value) of the ideal CLV drive is evaluated as the CLV drive error of the spindle motor.  Thus, a number of pulses positional error in a frequency of a basic clock or above is evaluated precisely.

Title: Modified copolymer having bicyclo orthoester group
Inventor: ENDOU TAKESHI
IPC: C08F24/00
Filed: 1980-09-18
Abstract: PURPOSE: A modified copolymer of an ethylenically unsaturated compound, useful in the production of volume shrinkage-free, well-adhering paints, internal strain-free adhesives, dimensional stability-requiring casting materials, etc., containing bicyclo orthoester groups.  
     CONSTITUTION: A modified copolymer of a bicyclo orthoester group-containing unsaturated compound, comprising structural units of the formula, wherein A is a monomer unit consisting of at least one ethylenically unsaturated compound, except the case where A consists of styrene alone, R is a lower alkyl and x and y are molar fractions of the repeating monomer units. When an ethylenically unsaturated monomer is homopolymerized or copolymerized, a considerable volume shrinkage occurs, whereas this copolymer, when crosslinked by opening the ortho ester ring, does not shrink but expands to an extent of about 1%. Accordingly, the copolymer is employed in moldings, castings, paints, adhesives, etc., which require dimensional stability.

Title: Method of fixing erosion shield to low-pressure rotor blade of steam turbine
Inventor: YOSHIKAWA SHIYUUHEI
IPC: F01D5/28
Filed: 1978-10-19
Abstract: PURPOSE: To provide a method of fixing erosion shield to low-pressure rotor blade of steam turbine, which is capable of preventing occurrence of crack or separation of the erosion shield during operation of steam turbine, by fixing the erosion shield to the rotor blade after pre-deforming the rotor blade or erosion shield to such an extent corresponding to the back-twist of the same caused when the turbine is set into operation.  
     CONSTITUTION: In fixing erosion shield 3 to rotor blade 1, shield 3 is so deformed that its inner surface conforms to the outer surface of rotor blade 1 where the shield 3 is to be fixed, by applying bending or torsional moment to the erosion shield 3 that is formed on the basis of contour of rotor blade 1 during rotation of the same. The shield 3 is fixed to the rotor blade by way of soldering or welding, while deforming the shield 3 to a shape shown by 3' in the drawing by applying force with jig 4 or the like. With such an arrangement, residual stress acted to the rotor balde 1 at the portion where shield 3 is fixed when the turbine is not in operation can be cancelled by the back-twist of shield 3 when the turbine is set into operation. Thus, when the turbine is kept in operation, stress acted at the portion rotor blade 1 where shield 3 is fixed is cancelled or lowered, so that occurrence of crack and separation of shield 3 can be prevented.

Inventor: OHASHI SHINICHI
IPC: B05D7/24
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To apply metal coating, with superior adhesion, to a carbon fiber reinforced plastic by a simplified method. SOLUTION: A paint 15, composed of a synthetic resin 14 with which metal grains 13 are mixed, is applied to the external surface 12 of a carbon fiber reinforced plastic 11.

When the collation means discriminates any defective component in the component sequence, the machine is stopped to allow the operator to inspect a defect of the sequencing device. Then, components are supplied to a carrier belt 24 via a transfer station. The belt is used to carry the components to an insertion machine.

Title: Clip type lead terminal and its manufacture
Inventor: NAKATSUMA YUUJI
IPC: H01R43/16
Filed: 1988-05-30
Abstract: PURPOSE:To prevent initiation of cracks by boring a small hole in the base of a clip, then dividing the clip alongside the line of cutting leading from this small hole to the tip of clip, and thus forming fingers of the clip. CONSTITUTION:A small hole 2c is bored in the center of the base (a part near the place between clip 2 and lead 2b) of a clip 2 of the terminal of a terminal material before forming, and the clip is cut along the line of cutting 9 leading from this small hole 2c to the tip of clip 2 and along line of cutting intersecting the first named line orthogonally. Then finger parts 2a of the clip are dislocated to the opposite sides so as to form a lead terminal. This enables sufficient securement of the width 11 of each clip finger 2a without requiring enlargement of the total width 6 of the clip 2, and further a recess is formed between the clip fingers. This eliminates generation of a force willing to tear the base of the clip, when the fingers 2a are to be dislocated, which should prevent initiation of cracks.
