Title: Non-reversible rotary motion transmission gear
Inventor: ICHINOSE MASANOBU
IPC: F16D41/00
Filed: 1979-02-15
Abstract: PURPOSE: To increase durability against reversely turning effect and ensure a smooth operation, by constructing a cylindrical friction surface, which is concentrical with a rotary axial core of the driven member, in a fixed drum provided to the stationary member, and pivotably mounting a pair of tightening cams, the tightening directions of which are opposite to each other, to the driven member.  
     CONSTITUTION: If an input shaft 1a is rotated in a direction of arrow mark, a plate 12 rotates together as a single unit, and its one pawl 7a presses in the loosing direction against a spring 6a to disengage one cam 5a, and a plate 11, that is a hollow shaft 2a is rotated together with the cam 5a. At this time, a friction force, generated between a cam 5a' and a cylindrical friction surface 4a, being acted in the loosing direction of the cam 5a', causes no disturbance for rotation. While a turning effect, if transmitted from the driven side, tends to rotate the plate 11 through the hollow shaft 2a, however, in either case of rotating direction, one of the cams 5a or 5a' is locked by producing a tightening force with the friction surface 4a, thus the rotary motion can not be transmitted to the input side.

Title: Testing method of directive light source
Inventor: SUZUKI KAZUNORI
IPC: G01M11/06
Filed: 1978-02-15
Abstract: PURPOSE:To make it possible to test the characteristics of a directive light source with the use of a simple device and by a simple operation by the quantities of the lights coming from a light source and entering the two regions, which are rotationary symmetrical about a preset axis, and by obtaining their ratio. CONSTITUTION:Among the lights emanating with intrinsic directive characteristics from a light source 1, the light having an angle smaller than theta1 with respect to an axis 2 enters a first light receiving device 5, whereas the light having an angle between theta1 and theta2 with respect to the axis 2 enters a second light receiving device 6.  Those lights are photoelectrically converted so that the output A from the first  device 5 and the output B from the second device 6 are detected by an output processing device. It is judged that as the output ratio A/B is the smaller the center  directive axis of the light source is dislocated the more from the axis 2 or the  directivity is weaker than the reference. Thus, those failing to reach a preset value  in the output ratio can be precluded as defectives.

Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To reduce a feeding loss by feeding power to slot antennas with a waveguide. SOLUTION: The plural slot antennas 9 are fitted in the peripheral direction of the ring-like waveguide 6 where a part is not connected at prescribed intervals. A coaxial waveguide converter 8 is formed at the end part of the waveguide 6. The length of the interval of the respective slot antennas 9 becomes half-wavelength in the intrawaveguide wavelength in a use frequency. An RF signal passing through the coaxial waveguide converter 8 is transmitted from the coaxial waveguide converter 8 to the slot antenna 9 through the waveguide 6, and it is radiated from the slot antenna 9 as a radio wave. The phases of radio waves radiated from the respective slot antennas 9 become common. Thus, the feeding loss can be reduced by feeding power by the waveguide 6.  In a system where the RF signal is transmitted through the waveguide 6, is guided to the patch antenna by a feeding probe and is radiated into a space by the patch antenna by using the feeding probe of the patch antenna, the phases of the radiated radio waves become common and the feeding loss can be reduced.

Title: Automatic resending system
Inventor: TANIGAWA TOSHIAKI
IPC: H04L23/00
Filed: 1985-01-31
Abstract: PURPOSE:To minimize the transmission loss time due to resending by reducing the volume of information to be transferred by plural transmission frames arranged on the leading part of a transmission format less than that transferred by another transmission frame. CONSTITUTION:When transfer data are sent to the transmission side, a Fleming P/S conversion part 15 in an ARQ11 outputs the transmission data (TMTDT) of the transmission frame to a circuit, and under unacknowledged status, the succeeding frame 1 is continuously outputted. On the other hand, the receiving side checks an error in a transmission frame 0 of receiving data (RCVDT), stores effective data (RXDAT) and returns an acknowledgement Ack. Since the returning side detects the Ack during the output of the transmission frame 1 with delay similarly to said operation, the transmission frame 0 1 is again outputted. Since the transmission frames 0, 1 are already regarded as effective data in the receiving side, only the Ack is returned.
