Abstract: A system for machining a component part having a race groove a along which ball elements run include a machine tool 3 for performing a machining operation on the component part, an acquisition unit 8 for acquiring information related to the machining operation, a control unit 4 for controlling the machine tool 3 based on the information acquired by the acquisition unit 8, a remote information processor 10 installed at a site remote from the control unit 4, and a communication system 9 for connecting the control unit 4 and the remote information processor 10 through a communication line 12. The remote information processor 10 has a capability of acquiring the information, acquired by the acquisition unit 8, through the control unit 4 and the communication line 12 and transmitting such information to the control unit 4 so that the component part can be machined to suit to a particular machining condition while satisfying a stabilized dimension.

Abstract: Disclosed are a equine interleukin-1 peptide which comprises a sequence comprising at least 5 continuous amino acids in a peptide represented by SEQ ID NO: 1 or NO: 2 in the sequence listing, DNA coding the equine interleukin-1 peptide, a recombinant vector containing the DNA, a transformant containing the recombinant vector, and a process for preparing an anti-equine interleukin-1 antibody, which comprises using the equine interleukin-1 peptide as an antigen.

Abstract: A device for electronically generating a sound according to the present invention includes an integrated circuit chip producing electronic signals corresponding to a desired melody, a switch controlling the ON and OFF states of the integrated circuit chip, a battery powering the integrated circuit chip, a sound generator having a dish-shaped vibrating plate and producing sounds responsive to the electronic signals, and a circuit pattern section having a plurality of lead portions interconnecting the integrated circuit chip, the switch, the battery and the sound generator. The circuit pattern section is formed by punching a conductive metal sheet in a press. Selected ones of the lead portions can advantageously be formed by punching into the battery holder or the switch. According to one aspect of the invention, an acoustic chamber is defined by the sound generator and a cover formed by potting or injection molding.

Abstract: A controller for a cutting machine has a machining power extracting unit for extracting machining power related to machining from the consumed power of the cutting machine, a detection range setter for setting a detection range for the machining power thus extracted, an integrator for integrating output values of the machining power extracting unit within the detection range thus set, a maximum value detector for detecting the maximum value of the output values of the machining power extracting unit within the detection range, and a judging unit for comparing an input signal with a variable comparative reference value and producing a control signal if the input signal exceeds the comparative reference value. The judging unit has an input which is selectively connectable to the machining power extracting unit, the integrator and the maximum value detector.

Abstract: A tool abnormality detecting device for a machine tool for machining a work with a machining tool selected according to a machining program. The device has a machining load detector for detecting a load during machining with a machining tool. A memory is provided to store threshold data for judging a tool life, detection starting time data and detection time data for each machining stage carried out with respective machining tools. Further the device is provided with a comparison/judgement unit for judging abnormality of the tool by taking detection data corresponding to the machining tool from the memory and comparing an output value of the machining load detector with a threshold within a detection time set in the detection data.
