Title: Rotary veneer lathe
Inventor: KAWAI KAZUYA
IPC: B27L5/02
Filed: 1997-12-16
Abstract: A centerless rotary veneer lathe comprises a slidable backup device which is disposed on the opposite side of a peeler log from a knife carriage of the lathe. The backup device has a pair rotatable rolls located one above the other with the axes thereof extending in parallel to the axis of the log. The paired rolls are disposed such that the axes of such two rolls are spaced at substantially the same distance from an imaginary line extending perpendicularly to the axis of the log and in parallel to the direction in which the backup device is moved. In operation of the veneer lathe with the rolls set in contact with the log periphery, the knife carriage and the backup device are moved synchronously at such a variable controlled rate that causes peeling of veneer with a predetermined thickness.

Abstract: The present invention relates to the use of cycloolefin copolymers for producingfilms. For cycloolefin copolymers, conditions have been found under which biaxially oriented films without heat-sealable layers can be firmly bonded with one another. The film temperatures found for this were above the glass transition temperature by from 5 to 70°C, and the times found were from 0.1 sec to 10 sec. As a result of the invention, layers made from cycloolefin copolymer and having a thickness ~ 50 µm have been used for the first time as heat-sealable layers, replacing cycloolefincopolymers having higher glass transition temperatures.

Title: Telephone switching system for easily implementing modification of connection information and medium storing telephone system control program
Inventor: WAKABAYASHI KUNIHIKO
IPC: H04M1/00
Filed: 1998-02-05
Abstract: A telephone switching system 10 comprises a plurality of physical ports 20, and switches removable terminals based on predetermined connection information, wherein such connection information is arranged to be capable of being stored and rewritten in a RAM 60 by inputting from the terminal.  When a physical port connecting to a terminal interface 30 is reconnected from a first terminal to a second terminal, a CPU 40 rewrites the connection information stored in the RAM 60 so that an extension number the user desires is stored for the physical port reconnected with the terminal.  Thus, connection information established for another terminal is prevented from being reflected as in the prior art, whereby a telephone switching system can be provided which does not cause mismatch of connection information such as an extension number.

Title: Sinker for selecting and controlling knitting movements of knitting tools in a knitting machine
Inventor: KOWITZ CLAUS
IPC: D04B15/68
Filed: 1996-10-01
Abstract: A control sinker is taught for selecting and controlling knitting movements of tools in a knitting machine driven by the relative movements of a plate support and a cam support.      The control plate can be forced into an engagement position with an output drive edge of an output drive component to transmit the deflection drive by the action of a minimum pre-tension of an extended rod-shaped control spring. The free end of the spring is supported to slide on the base of a guide groove accepting the control plate, and is constructed as a one-piece spring steel component to simplify manufacture and increase its wear resistance. The spring width (h) measured perpendicularly to a neutral elastic line of the control spring at the base side of the spring at which it bears on the basic body of the plate is greater than at the free end of the spring by which the spring is supported on the base of its guide groove. The spring bears on the basic body of the plate via a smooth curve widening the base region.

Abstract: A temperature conduction with high decision in a state that the changing of temperature of cooling water in an engine is forecast, and achievement of a cooling control system with the improved life and reliability and the reduction of costs. A butterfly valve 34b for regulating the flow of cooling water is rotatably controlled through a DC motor 31, a clutch mechanism 32 and a deceleration mechanism 33 so as to cool the engine at an appropriate temperature. A PWM signal generated by a quick response control and a PI control on the basis of at least load information of the engineis supplied to the DC motor 31 from ECU, whereby the butterfly valve 34b is rotatably controlled. A butterfly valve 133 adjusting the flow of cooling water is controlled with the degree of valve opening by a thermo-element 135 enclosing a thermal expansive body such as wax. A PTC heater 140 is placed to the thermo-element 135, and supplied with current for heating on the basis of operation parameters of an engine to control the cooling efficiency of the cooling water. In consequence, the characteristics of the butterfly valve which is capable of extremely decreasing rotation torque for adjusting the flow of thecooling water is used, so that elements of mechanical stress can be reduced, resulting in the improved life and reliability.

IPC: B23B27/16
Filed: 1997-10-17
Abstract: A cutting tool assembly which includes a shank (1) and a removable cartridge (3) on which is mounted a cutting insert (5). The shank (1) is for mounting the assembly on a cutting machine. The cartridge (3) is removably mounted by a screw fastener (7) which passes through a hole in shank (1) into a threaded hole (31) in cartridge (3). The shank includes a recess (9) having sloping facing walls (15, 17) for engaging a complementary seating portion, having sloping walls (25, 27), of cartridge (3). The recess (9) and complementary seating portion of the cartridge are shaped such that the cartridge is wedged in the recess when the screw fastener (7) is tightened. The invention allows a reduction in costs by providing for the exchange of cartridges rather than a whole cutting tool. The wedging interconnection of the cartridge and shank ensures rigidity of the assembly. A modification is described wherein a recess for a screw fastener is provided instead of a hole (23) which allows for quick exchange of cartridges.
