Title: Steel material position detecting method in compression joint parts of steel-cored stranded cables
Inventor: TAKAHASHI HIDEO
IPC: B23K20/00
Filed: 1978-05-31
Abstract: PURPOSE: To eliminate the need for sensitiveity adjustment and zero point adjustmet of magnetic  detectors and make detection with high sensitivity by comparing the signal immediate befor the  magnetic detector as a reference signal with the signal immediate thereafter in the moving process of said detector and detecting the magnetic pole having maximum magnetic force, i.e., the  end part of a steel material.   
     CONSTITUTION: A magnetic detector 3 composed of a Hall effect element or the like is moved  along a compression-joint part 2 to electrically detect the magnetism from the steel core 1a in a  socket 2c through a non-magnetic jumper socket 2c. The output signal of the detector 3 is  integrated in a peak value holding circuit 5 through a polarity changeover circuit 4 to maintain  the maximum signal thereof. This signal is used as a reference signal. A comparator 6 compares  the output signal b from the circuit 4 and the reference signal b' from the holding circuit 5 and  generates an output signal c when these become b<b'. Hence, it is when the detector 3 positions  at the end part of the steel core 1a in the compression-joint part 2 that the comparator 6 generates  the output signal c. The output signal c is differentiated in a differentiating circuit 7 which in  turn generates the pulse signal d. This positive pulse signal e is sent to a display device 6 to display the steel core end part position.

Title: Camera having operation display means of automatic dimmer type strobe
Inventor: KITAGAWA MASAHIRO
IPC: G03B17/20
Filed: 1978-05-31
Abstract: PURPOSE: To rapidly perform flash photography without any hindrance by emission- displaying  the light dimming operation of strobe with the light emitting body disposed in the finder of the  camera.  
     CONSTITUTION: When a main capacitor C 1  is charged and a flash discharge tube F reaches a  flashable state, a light emitting body B 2  emits light to display the completion of charging and at  the same time its lighting current causes the light emitting body P 1  in the finder of the camera 1  to emit light and therefore a photoelectric mark lights, from which the completion of the charging of the capacitor C 1  may be known in the finder. Next, when the discharge tube F emits light  upon shutter release and flash photography is completed, the charging charge having been stored  in the capacitor C 3  is applied to the capacitor C 2  by its charging current and when a fixed voltage  is reached, the light emitting body B 1  emits light. When discharge is started, the internal resistance of the light emitting body B 1  lowers and the discharge end voltage also lowers and therefore  it repeats flickering until there is no more discharging charge of the capacitor C 3 . This flickering  current causes the light emitting body P 1  in the finder to flicker in synchronization to the light  emitting body B 1 , thus displaying that light dimming operation has been effected normally.

Title: Tdd radio communications system
Inventor: SATO HIROTSUGU
IPC: H04J3/00
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To improve the connection possibility between a master station and a slave station to improve the throughput of data transmission and to reduce the power consumption of the slave station by allowing the slave station to detect the receiving field strength of a signal received from the master station and to adjust the transmission power of a signal to the master station in accordance with the detected receiving field strength. SOLUTION: When slave stations (UM) 3 receive an informative signal from a master station (CM) 1, they decide whether or not this receiving field strength is larger than a reference value, lowers the transmission power of a signal to be transmitted to the CM 1 when it is larger than the reference value and increase the transmission power of the signal to be transmitted to the CM 1 when it is smaller than the reference value. That is, the UMs 3 transmit a signal with large transmission power when the CM 1 is far away, and transmit the signal with small transmission power when the CM 1 is near to prevent the dissipation of transmission power because the receiving field strength is connected with being in inverse proportion to the square of distance. Then, the UMs 3 can perform radio communication due to a TDD procedure with power saving.
