Title: Solid laser oscillator
Inventor: OKA MICHIO
IPC: H01S3/042
Filed: 1990-07-25
Abstract: PURPOSE:To stabilize the output for the increase in the output limit and the miniaturization of the title solid laser oscillator by a method wherein a photo- transmitting heat sink in higher thermal conductivity than that of a solid laser medium is provided on the part to be irradiated with the pumping beams emitted from the excited light source of the solid laser medium. CONSTITUTION:A disc type heat sink 9 made of diamond is sticked on the left side end of a solid laser medium 5 through the intermediary of a mirror coat 6. Next, the outgoing beams from respective laser diodes 1 are entered into respective optical fibers 2 while the flux of the laser beams (pumping beams) L1 emitted from the other end of an optical fiber handle 3 is focused by a focusing lens 4. Next, the medium 5 is irradiated with the laser beams transmitting through the heat sink 9 to be excited so that the oscillated laser beams in proper wavelength may be generated to be respectively reciprocated between the mirror coats 6 and 8 thereby emitting a part of the laser beams as the output laser beams L2 passing through an output mirror 7. Through these procedures, the output limit decided by the thermal conductivity of the medium 5 can be increased thereby enabling the miniaturization of the title solid laser oscillator to be facilitated.

Title: Inspection instrument for stripe pattern
Inventor: YAMADA MITSURU
IPC: G01B11/02
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To inspect an exact BM stripe pattern by examining not only an average width and pitch of a BM stripe (RGB stripe) but also variations in its size and pitch. SOLUTION: A standard stripe pattern panel, integrated into an inspection system of a stripe pattern inspection instrument, is regularly checked to automatically diagnose the inspection system precision of an inspection instrument. Moreover, information obtained by managing the trend in inspection values of an actually inspected stripe pattern can be fed back to an exposure board 20 on which a BM stripe pattern is formed. A stripe pattern is inspected by automatically controlling the X and Y coordinate axis directions of a modulated light 6 for the exposure board 20 and/or the illuminance of an exposure light source 4.

Title: Hot water treatment of aluminum or aluminum alloy
Inventor: SHIRAISHI SADAO
IPC: C23G1/24
Filed: 1995-07-10
Abstract: PROBLEM TO BE SOLVED: To treat with a hot water without discoloring aluminum by adding a niobium compound into a treating water to specify the concn. of niobium in the hot water in the hot water treatment of an aluminum material. SOLUTION: In the hot water treatment of aluminum or an aluminum alloy, a treating water prepared by adding a niobium compound in a hot water to be 5mg/L in niobium concn. in the hot water is used. Niobium added into the hot water forms a composite material with trace impurities such as Ca, Si, Fe in city water or well water to suppress the ionic activity of the elements. Then, when the water containing impurity ions is used for the hot water treatment, the ions are not adsorbed on the surface of aluminum and not incorporated into a hydrated oxidized film on the surface and the formation of discoloration region is prevented.

Title: Tension servo device
Inventor: YOKOYAMA YOSHIHIKO
IPC: H02P29/00
Filed: 1990-07-27
Abstract: PURPOSE:To improve control accuracy and miniaturize it by accessing the data to offset torque ripple and changing over the gain of motor drive controls, and compensating the change of winding diameter by a winding diameter compensating means, and electrically generating a rotational angle to the reference signal of rotation by a rotational angle generator. CONSTITUTION:The torque control data, which are accessed from a torque data control data storage means 8 by a rotational angel detection means 7, changes over the gain of motor driving controls 6. Therefore, the torque ripple of high frequency is suppressed. Moreover, the application voltage Vm, which is proportional to the rotation cycle gotten by a winding diameter compensating means 10, is made in motor driving controls 6, and is supplied to a motor 4, and the tension ripple by the winding change is suppressed without using a tension detector. Furthermore, by a rotational angle generator 9, a rotational angle occurs electrically to the reference signal to the reference signal of rotation. Therefore, the tension servo device can be made simple in structure, and miniaturized.

Title: Built-up reamer
Inventor: MIYAZAKI KATSUMI
IPC: B23B31/11
Filed: 1993-07-16
Abstract: PURPOSE:To facilitate change and assemblage and improve boring accuracy by incorporating a tip in an inclined side end face of the guide part of a holder which is inclined by a predetermined angle to a surface orthogonal to the axis of a reamer. CONSTITUTION:A tip 1 under the assembled condition makes an angle theta inclination to a surface orthogonal to the axis of a holder 2. The largest outer diameter point 31 of a chamfer is biased to the tip side from the tip position 32 of a second margine 22 by a bearing clearance delta in the axial distance of a reamer. Further, this bearing clearance delta may be of a positive value, preferably a small value. This is because the second margine 22 has also a function of a guide part for ensuring accurate feed of a chamber 3 in the direction of the reamer shaft. When the delta is too large, the working accuracy tends to be degraded.

Title: Production of polyacetylene
Inventor: MINO NORIHISA
IPC: G03F7/025
Filed: 1988-08-09
Abstract: PURPOSE:To obtain a polyacetylene in high yields by forming a monomolecular film from the molecules of a linear hydrocarbon having a side chain in the main chain, a COOH group on one end of the main chain, and an acetylene group between two arbitrary adjacent carbon atoms and polymerizing the acetylene group by irradiation with energy beams. CONSTITUTION:A hydrophilic film, e.g., SiO2 film 2, is formed on a substrate 1 (e.g., semiconductor Si substrate), and a monomolecular film 5 of a linear hydrocarbon molecule 3, for example, one of the formula, wherein p, q, r and s are each an arbitrary integer; this molecule has a side chain at the (r+1)th carbon atom from the COOH group and acetylene groups 4 on the (q+1)th carbon atom on the main chain from said carbon atom and on the (t+1)th carbon atom on the side chain. The film formation is performed in a state in which the CH3 group on the terminal of the main chain and the CH3 group on the side chain are aligned on the surface of the substrate. This film 5 is irradiated with, for example, ultraviolet rays to effect a photoreaction of the acetylene groups to form a polyacetylene 6 having a conjugated system. Since the density of the acetylene groups is twice as high as that of the conventional, the photoreaction is quick and the film can be released from a structural strain because both the main chain and the side chain form polyacetylene.
