Title: Intermediate bearing for screw conveyor device
Inventor: YAMADA TAKESHI
IPC: B65G33/32
Filed: 1984-03-14
Abstract: PURPOSE:To prevent a conveyor from shaking by providing radially projecting leg parts on a bearing part which supports the rotary shaft of a spiral screw housed in a hollow shaft cylinder, and allowing objects being conveyed to pass through space parts enclosed by said shaft cylinder, bearing, and leg parts. CONSTITUTION:A bearing part 4 supports the rotary shaft of a spiral screw housed in a hollow shaft cylinder 2, and leg parts 6 are radially projected out from the bearing part 4, fixed to the shaft cylinder 2, and support the bearing part 4. Objects 8 to be conveyed are made pass through a space 9 enclosed by the shaft cylinder 2, bearing part 4, and leg parts 6. The leg parts 6 are formed thinner on the upper course side, and formed thicker on the lower course side, supporting the midpoint of the spiral screw, to enable objects 8 being conveyed to pass through, while preventing shaking and, thereby, enabling a fairly long screw conveyor device to be manufactured.

Title: Directional coupler optical switch
Inventor: IKEDA MAKOTO
IPC: G02F1/313
Filed: 1988-03-01
Abstract: PURPOSE:To reduce a necessary operating voltage by specifying the length of the coupling area of two directional couplers which are arranged in parallel. CONSTITUTION:The propagation constant difference generated when one of TE and TM modes is propagated in two waveguides while an electric field is applied is DELTAbeta1, and the propagation constant difference generated when the other mode which crosses said mode at right angles is propagated is DELTAbeta2. Then when alpha=DELTAbeta1/DELTAbeta2, 0.28<=alpha<=0.31. Further, the length of the coupling area of the directional couplers is denoted as l and the complete coupling lengths for the TE and TM mode waveguide light beams are denoted as LTE and LTM. In this case, either of the ratios l/LTE and l/LTM is denoted as x1 and the other is denoted as x2; and the l, LTE, LTM and alpha are so determined that expression I and II hold at the same time. Consequently, the arrangement of X or Y propagation is usable without using the arrangement of Z propagation and low-voltage operation is enabled.

Through pulse generating circuit 9 and gate circuit 10, a P pilot signal shifting in phase is inserted 11 into the horizontal blanking part of a luminance signal and then frequency conversion 12 is performed to obtain an angle-modulated signal with a high frequency band. On the other hand, the chrominance signal extracted by band-pass filter 13 is inputted to rinning oscillator 15 and converted 14 into a low- frequency signal via frequency converter 16, which is recorded on a medium by being mixed 17 with the angle-modulated signal. Thus, a color signal suitable to high- density recording is obtained to reduce a shift in color phase due to the jitters of the color signal in reproduction.

Title: Telephone set calling system
Inventor: WATANABE MASAAKI
IPC: H04M1/72
Filed: 1986-03-07
Abstract: PURPOSE:To call a caller by separating a calling channel while connecting a caller to the line DC-wise as it is by operating a mute circuit at the time of calling between telephone sets connected to the same line, and separating the calling circuit from the line. CONSTITUTION:When a caller-side telephone set 310 is hooked off, an exchange 101 inverses the polarities of a line 1 and a line 2 respectively to 'negative' and 'positive'. After receiving a dial number, the exchange 101 temporarily turns the said polarities respectively to 'positive' and 'negative' in order to recognize the caller-side telephone set 310. In the telephone 3 a loop same as that for waiting is formed, and the exchange 101 recognizes the telephone 310. When the exchange 101 returns the polarities of the lines 1 and 2 to original ones, the transistor 14 of an erasing circuit 100 turns ON for a prescribed time, and the calling circuit 21 is separated from the line, however, a transistor 18 continues the closing of a DC loop instead of it.
