Abstract:
A tube bending system for bending all tubes in a preset manner effectively from the beginning of works by detecting a degree of bending of a tube which varies during a bending process in high precision by a displacement sensor and by accurately comparing the detected value of the degree of bending of the tube detected by the displacement sensor with a control value written in advance in a program in a memory. The displacement sensor is disposed so as to be able to detect the position of the tube to be bent on the side of a reaction receiving section between a gripper and the reaction receiving section. The displacement sensor is composed of a detecting section and a transducing section. A value which indicates the position of the tube to be bent detected by the detecting section is transduced to a degree of bending of the tube to be bent by the transducing section and the transduced degree of bending is transmitted to a controller during repetitive operation for bending the tube so that the degree of bending approaches to the predetermined degree of bending.
Abstract:
There is provided means for bending a small diameter metal pipe capable of accurately finishing all of bending operation by a single bender even when a linear length of a pipe distal end portion is short. A method of bending a small diameter metal pipe for chucking one end of the small diameter metal pipe to be worked, setting a working direction and carrying out bending operation from a front end side of other end to the one end, characterized in that bending operation of one step or several steps is carried out previously from a pipe distal end of the one end, a portion subjected to the bending operation is chucked and bending operation is successively carried out from the front end side of the other end toward the one end subjected to the bending operation under the state.
Abstract:
A microcomputer is provided in an earphone-microphone device for the purpose of controlling the transmission/receipt of data with respect to a portable cellular phone by way of a serial data signal line and a serial clock signal line, the operation of a liquid crystal device driver, and the operation of a drive circuit of a vibrator. As a result, an earphone-microphone device itself can perform typical functions of the cellular phone, such as retrieval of phone-number-related data stored in the cellular phone, displaying of the thus-retrieved data, origination of a call to the called party indicated on a display, and actuation of the vibrator when there is an arrival of an incoming call.
Abstract:
A radio system has a transmitting circuit for tuning in a transmitting frequency at a desired frequency, a control circuit for performing control of the whole of the radio system, a clock oscillation circuit operative to generate a reference clock for the control circuit, a memory circuit operative to store conditions for switching the oscillation frequency of the reference clock to be generated by the clock oscillation circuit, a comparative arithmetic circuit for comparing a transmitting frequency tuned in by the transmitting circuit with the conditions stored in the memory circuit, and a frequency switching circuit for switching the oscillation frequency of the reference clock to be generated by the clock oscillation circuit, on the basis of a result of comparison by the comparative arithmetic circuit. The oscillation frequency of the reference clock to be generated by the clock oscillation circuit is switched by controlling the frequency switching circuit on the basis of a result of comparison by the comparative arithmetic circuit.
Abstract:
A radio communication apparatus has a plurality of communication functions such as an incoming call sound, an incoming call ringing pattern, an incoming call vibration, a received voice volume, a microphone sensibility, a noise canceling, a key confirming sound and a message recording, and a plurality of operation conditions of the communication functions are stored in a operation condition storing unit for each of a plurality of operation modes suitable for various environments. When a user selects a particular operation mode suitable for user's environment by pushing a mode selecting button, particular operation conditions of the communication functions corresponding to the particular operation mode are read out, and communication functions of a speaker, a vibrator, a buzzer, a noise canceler, a microphone and a message recorder are simultaneously set to the particular operation conditions. Therefore, when an incoming call and a caller's voice are received, the incoming call is rung at a pattern and a sound volume suitable for the user's environment, and the caller's voice is output at a sound volume suitable for the user's environment.
