Publication number: 20020023490Abstract: Multi-symbol refractive encoding of distance or level along a scale provides an advanced means for measuring liquid level or dissimilar-liquid interface level with a float. Distance or level information is encoded in the patterns of microfacets impressed in the scale. The microfacets divide and direct incident visible or infrared beams toward or away from detectors disposed in arrays. This approach provides significant reductions in the number of encoding tracks and of the size of the float, improved accuracy, fault detection, increased span, less friction, and easier installation. A slender rod can replace the wide encoding tape of prior designs. The rod can also be used to guide optical or acoustic signals efficiently from floats to the rod support and thus on to level indicating and recording devices. In addition, the rod support provides means for quick installation, signal coupling, and setting reference levels.Type: ApplicationFiled: August 8, 2001Publication date: February 28, 2002Inventor: Alan Alexander Burns

Publication number: 20020023525Abstract: The invention provides a clamping device for machine tools capable of preventing the occurrence of impressions. In a clamping device for machine tools, a tailstock (movable carriage) is provided on a top face of a fixed bed and the tailstock is positioned and fixed with respect to the fixed bed. The tailstock is supported by linear-motion bearings (guides) which are disposed between the tailstock and the fixed bed. Blocks are slidably engaged with rails extending in the travel direction with rollers interposed between them. Further, a recess portion extending in the travel direction is formed in the top surface of the fixed bed. A cylinder mechanism is arranged so that left and right inner walls in the recess portion are pressed by a pair of pistons provided on the undersurface of a headstock.Type: ApplicationFiled: August 29, 2001Publication date: February 28, 2002Inventors: Masamitsu Nakaminami, Yoshinori Sakashita

Publication number: 20020023526Abstract: The present invention relates to a film cutter assembly in which a blade housing slides along a pair of rails. The blade housing is formed of an upper portion for housing the blade. Either end of the upper portion has a rounded inclined shape from a bottom edge to form a sled shaped runner. The sled shaped runner extends beyond the blade such that the user is prevented from touching the blade. A lower portion of the blade housing slidables bilaterally in a cavity formed below the rails. A clearance is formed between the blade and the rails to allow the blade housing to easily slide over a film to be cut even if the film bunched or doubled over. The upper portion of the blade housing has a concave shape for allowing a user's fingers to easily grip the blade housing. Preferably, the rails are formed of a material which provides an attractive charge to attract the film to the rail and help hold the film flat before and after cutting. For example, the rails can be formed of flexible vinyl or acetal.Type: ApplicationFiled: December 20, 2000Publication date: February 28, 2002Inventors: Paul Vegliante, Sean Neiberger, Rudy Pavlik, Ian Kaiser

Publication number: 20020023527Abstract: A guide for the blade of a band saw providing support for the rear edge and sides of the blade. The guide utilizes two cylindrical rings or anvils that may be adjusted to contact the sides of the blade. A rotating spool within the anvils provides the support for the rear edge of the blade. The spool may be easily adjusted to provide support for blades of varying depth. The entire guide may be mounted on the guide arm of most band saw blades and pivoted into position through the use of an adjustable saddle.Type: ApplicationFiled: April 12, 2001Publication date: February 28, 2002Inventor: Larry Wood

Publication number: 20020023528Abstract: A scribe device comprises a body (10). A holder (20) is supported by the body (10) such that the holder (20) can slightly slide in a direction of a slide axis (Lb) which intersects a surface of a workpiece (100). Retaining portions (15, 21) spaced apart in a direction of the slide axis (Lb) are formed on the body (10) and the holder (20), respectively. A vibratory actuator (40) is sandwiched between the retainer portion of the body and the retainer portion of the holder. The holder (20) holds an abutment member (30). The holder is biased by a biasing member (23) such that said retaining portion of the holder is pressed against the vibratory actuator. The vibratory actuator renders the vibrations in the direction of the slide axis to the holder. The abutment member transmits the vibrations from the holder to the workpiece. That is, the abutment member (30) is subjected to a static force and a vibration energy and pressed against the workpiece (100).Type: ApplicationFiled: December 2, 1999Publication date: February 28, 2002Inventors: GYO SHIMOTOYODOME, ISAO SUGIURA

Publication number: 20020023529Abstract: There is input type information defining a type of portable terminal as well as various music composing parameters. Automatic music composition process is carried out on the basis of the input type information and music composing parameters, so as to generate musical composition data suitable for reproduction on a portable terminal of the type indicated by the type information. Balance in predetermined musical characteristics of the generated musical composition data can also be achieved by adjusting the predetermined musical characteristics in accordance with the type of portable terminal. It is also possible to convert the generated musical composition data into a predetermined data format suiting the type of a portable terminal to be used. The generated musical composition data may be transmitted online to the portable terminal.Type: ApplicationFiled: August 9, 2001Publication date: February 28, 2002Applicant: Yamaha CorporationInventors: Yasushi Kurakake, Toshiyuki Ito, Masahiro Koyama

Publication number: 20020023530Abstract: To a tone generation apparatus is removably attachable a plug-in board for generating a tone on the basis of performance information and extending the tone generating function of the tone generation apparatus. Tone color name information and tone color parameter name information of tone color data possessed by the attached plug-in board is stored in a nonvolatile memory. Thus, any tone color possessed by the plug-in board can be known with reference only to the nonvolatile memory and without a need to refer to the plug-in board. The nonvolatile memory can also store tone color data of a custom voice obtained by editing original tone color data of the plug-in board. With this arrangement, the plug-in board is allowed to obtain the tone color data of the custom voice from the nonvolatile memory, as necessary.Type: ApplicationFiled: August 22, 2001Publication date: February 28, 2002Applicant: Yamaha CorporationInventors: Takeshi Komano, Tetsuo Okamoto, Motonori Sunako

Publication number: 20020023532Abstract: A system for remotely controlling an undersea device. The system employs a gas-pressurized liquid reservoir that can be recharged from at least one replaceable gas bottle. A pressure-regulating valve is employed to control the pressure of the liquid leaving the reservoir. A number of one-shot units, each in the form of a squib-actuated valve coupled with a piston accumulator, are employed to create a hydraulic pilot for a hydraulic direction control valve. The control valve functions to direct pressurized liquid from the reservoir to a hydraulic actuator or other type of hydraulic device.Type: ApplicationFiled: August 27, 2001Publication date: February 28, 2002Inventor: Don B.
