Title: Fitting structure for magnetism producing body to rotating body
Inventor: KATSUSAWA YUKIO
IPC: G01D5/12
Filed: 1984-04-06
Abstract: PURPOSE:To fit the magnetism producing device to a rotating body which rotates at a high speed with sufficeint strength by fitting the magnetism producing body in the hollow part of a holder of a nonmagnetic body fixed in a recessed part in the end part of the rotating body. CONSTITUTION:The rectangular recessed part is formed in the end surface 11a of a gear 11 as the rotating body and the holder 13 made of stainless steel (nonmagnetic body) is fitted therein. The hollow part 14 which extends in the rotating direction of the gear 11 is formed in the holder 13 and the magnetism producing body 15 which matches with its sectional shape is inserted. The holder 13 has a box-shaped high-rigidity structure and when the gear 11 rotates at a high speed, the magnetism producing body 15 is pressed against internal walls 14a and 14b of the hollow part 14 of the holder 13 with centrifugal force and the holder 13 is pressed against the internal wall 12a of the recessed part 12 of the gear 11. Consequently, no unreasonable force is applied to a screw 16 and the magnetism producing body 15 is fixed strongly to the gear 11 through the holder 13.

Title: Transmitter
Inventor: INUI KENICHI
IPC: H04Q9/00
Filed: 1985-03-30
Abstract: PURPOSE:To prevent the situation that a sending data is thrown away due to collision by decreasing the polling interval of a master station than the minimum value of the retransmission wait time at collision possessed by each terminal station. CONSTITUTION:Suppose that a state change takes place in a supervision data at the side of a terminal station 2-1 on the way of the polling processing of the j2 and the change becomes a cause to start the supervision data random transmission to the master station. The terminal station 2-1 counts the carrier sense time from the end point of time of the polling processing #2. Since the polling interval tp is set shorter than the carrier sense time t1, the carrier sense does not reach the time t1 only and the signal of the next polling processing #3 is detected. Thus, the count of the carrier sense time is initialized to 0 again, the processings as above are repeated, and when the polling processing #N is finished finally, the supervision data random transmission of the terminal station 2-1 is performed after the wait time by t1 from the point of time.

Abstract: PURPOSE: To exactly measure a distance with a game so that a shooter can surely snipe the game by measuring a time interval between the outgoing time of a laser beam and the time when a laser beam reflected by the game enters a photodetector. CONSTITUTION: The instruction for turning on a laser is issued to a laser beam source 21 by a laser source control device 31 in order to measure the distance with a game when the image of the game is comfirmed and the laser beam is transmitted from the laser beam source 21. The time when the instruction of turning on the laser beam is issued is sent to a range finding device 33 and time counting is started. The laser beam reflected from the game is made incident on a light receiving element 22, converted to a current, inputted in a receiving light signal amplifier circuit 32, amplified and the time count is finished when the amplified current is inputted to the range finding device 33.  Consequently, the elapsed time between the time issuing the instruction and the time when the light signal amplifier circuit 32 sends the current to the range finding device 33 is obtained and the distance with the game is obtained instantenously by substituting the time for a prescribed equation.
