Inventor: HASEBE SADANORI
IPC: H04N5/44
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To provide an automatic presetting device of a channel capable of automatically omitting an unnecessary channel after automatically presetting the channel. SOLUTION: A channel is automatically seeked and preset to a memory by tuning in steps S11 to S14. The automatically preset channel is successively scanned again to tune in a step 15. The presence/absence of a synchronizing signal in each tunned channel is decided in a step S16. A channel decided to have no synchronizing signal is deleted from the memory in a step S17.

Title: Material testing machine
Inventor: SHIBATA NARIO
IPC: G01N3/00
Filed: 1987-07-21
Abstract: PURPOSE:To prevent the breakage of a load cell, etc., by actuating a loading mechanism in a direction indicated by an instruction from an operating key only in the case where the loading direction set by the operating key is different from that working on a test piece when the loading mechanism is stopped on the account that the load added to the test piece exceeds the tolerance limits. CONSTITUTION:A CPU 27 monitors the measuring range of a load amplifier 22. When the CPU 27 detects that the present load is over the tolerance limits, the CPU 27 controls a motor driver 24 to stop a motor 16. Then, in order to remove the load acting on a test piece 15, an operator manipulates an operating key 25. As long as the operating key is correctly manipulated, the direction of the load acting on the test piece 15 and that indicated by an order inputted through the operating key 25 are reverse to each other. Therefore, the motor 16 is driven in a direction reverse to that of the load acting on the test piece 15, thereby removing the load from the test piece 15. In this case, even if the operator manipulates the operating key 25 erroneously, a cross head 13 is not moved and therefore, excessive load is never further charged on the test piece 15.

Abstract: PURPOSE:To save the memory capacity by reading a waveform data based on a step data corresponding to a frequency of an object waveform and setting time data corresponding to the data with a half period cycle of a carrier wave to a real timer. CONSTITUTION:The method is provided with a memory 6a splitting a sinusoidal wave 1 equally and storing the height of the sinusoidal wave 1 at the split position, a memory 6b storing an interval from the low or high level of a carrier wave 2 superimposed on the sinusoidal wave 1 an interval from the low or high level of the carrier wave 2 superimposed on the sinusoidal wave 1 till the prescribed position of the carrier wave 2 corresponding to the height as time data and a memory 6c storing the data of a step number reading the data of the memories. Then the time data based on the step data is set to a real timer at a half period cycle of the carrier wave and the output waveform from a real time I/O port is used as a PWM waveform of a simulated sinusoidal wave. Thus, even when the memory capacity is small, the PWM waveform output of the sinusoidal wave with various different object frequencies is obtained.

Title: Optical fiber cable
Inventor: AKIYAMA TSUTOMU
IPC: G02B6/44
Filed: 1992-06-16
Abstract: PURPOSE:To prevent the optical fiber cable from being adversely affected by the permanent set in winding even if units have such permanent set in winding. CONSTITUTION:The curvature of doubling and twisting of the units of the optical fiber cable constituted by spirally doubling and twisting plural pieces of the trough-shaped units 1 in >=1 layers around a tension member 2 and laminating and housing plural sheets of ribbons 3 of coated optical fibers within the units 1 is set equiv. to the curvature of the winding diameter of the units 1 wound around a drum before the doubling and twisting. As a result, the permanent set in winding is absorbed when the units 1 are doubled and twisted around the outer peripheries of the tension member 2 to form the cable even if the units have the permanent set in winding and, therefore, the units 1 are easily doubled and twisted and the cable formed by doubling and twisting the units 1 is made straight. The transmission characteristics thereof are thus stabilized.
