Title: Automatic transmitter circuit for morse code
Inventor: FUJII TADAAKI
IPC: H04L15/18
Filed: 1978-11-10
Abstract: PURPOSE: To reduce the memory capacity of an automatic Morse code transmitter circuit for a transceiver, etc., by reading out Morse codes in sequence assigning addresses of a memory unit by a counter supplied with clock pulses.  
     CONSTITUTION: When switch SW14 is tilted momentarily to the right, counter 5 is reset and outputs Q 1 ∼Q 7  are all zero. Here Q 1  is zero and inverter 3 applies a signal to gate 2, where clock pulse (a) passes and is supplied to counter 5, which starts counting up. As a result, Q 1 ∼Q 7  increase in a binary mode and in accordance with those increases, addresses of ROM6 are assigned to read out corresponding memory contents in sequence. Then although signal (g) expressing Morse codes is generated at the output of gate 9, timing circuit 4 generates a low-level signal at output (b) in a period of 2.5T when it expresses a dash, thereby stopping clock pulses from appearing at output (c) of gate 2. Consequently, the advance number of counter 5 becomes equivalent to a read of dots, spaces and dashes.

Abstract: PURPOSE: To check the run-out of rotary shaft by partitioning off a plurality of static pressure pockets in circular form such that they surround the rotary shaft, and displacing one end and the other end relatively in the direction of rotation of the static pressure pockets in the circumferential direction. CONSTITUTION: Small projections 52 lie extensively in the axial direction at a rotary shaft 34, and when it faces static pressure pockets 36a, the rotary shaft 34 is displaced in the opposite direction to the projections 52. The projection 52 come to the corner 44a of the static pressure pocket 36a by the revolution of the rotary shaft 34, and it relatively shifts an edge 38a, and the area of the projection 52 opposed to the static pressure pocket 36, and the fluid pressure applied to the projection 52 lessens gradually, and the rotary shaft 34 is biased in the direction of center of the axis. Right before the projection 52 reaches the corner 42a, it comes to the corner 348b of the edge 40b, and fluid pressure is applied from the static pressure pockets 36a and 36n to the projection 52.  The pressure added to the projection 52 changes gradually at the edges 38a-38d and the edges 40a-40d, so the bias of the rotary shaft 34 does not occur suddenly, and run out does not occur.

Title: Dial unit
Inventor: OOOKA TAKAO
IPC: G05G1/08
Filed: 1978-11-11
Abstract: PURPOSE: To make it possible to reduce torque of a rough adjustment dial when this dial is used, by providing a constitution, where touch of the rough adjustment dial with operator's bare hand is detected to switch small-size friction plates, in respect to the dial unit for a signal generator, a wide-band radio receiver, etc.  
     CONSTITUTION: When an operator touches rough adjustment dial 1 with his hand, the commercial frequency voltage induced by the operator is transferred to the inside of a unit through dial 1, contact spring 11, metallic plate 12 and terminal 17. Next, the switch connected to terminald 17 detects the commercial frequency voltage to drive electromagnet 8, and therefore, small-size friction plate 6 is lifted to disconnect the contact part between two friction plates 5 and 6 because movable piece 9 presses down the right end of cam 10, thereby reducing considerably rotation torque of dial 1 (because a main load of dial 1 is friction plate 6). Next, when the operator takes off his hand from dial 1, friction plates 5 and 6 are brought into contact with each other again by action of winding spring 7, so that decelerated rotation can be performed by fine adjustment dial 2.
