Title: Signal forming device
Inventor: SAWADA MICHIHIRO
IPC: H04L27/32
Filed: 1980-03-05
Abstract: PURPOSE:To provide a response signal of high-duty ratio as high compression gain against a barker code-used system for a radar, etc. by forming a synthesized signal with a barker code deviated by a prearranged bit. CONSTITUTION:If a 5-bit barker code 100 is processed by mans of a delay circuit 121 to 124, a positive polarity converter 131, 133 to 135, a negative polarity converter 132, etc., the code 100 is compressed by means of a synthesizer 140 to an amplitude five times as much as the original code. In addition, if this compressed code is synthesized deviated by two bits, the duty ratio of an output wave form is high such as 50%, etc. Consequently, in an enermy and friend response system using a barker code under a two-dimensional radar, etc., the number of barker code bits of a target radar is analyzed, generating a barker code from a carrier generation circuit 200 in accordance with said bit number. Then the bit number in accordance with a  barker code bit number is controlled at a modulator 201 by means of a modulation  control circuit 202. As a result, it is possible to transmit to a target radar a response  signal at high compression ratio and high duty ratio.

Title: Automatic discriminating device of tape recording speed
Inventor: KAMOGAWA TAKESHI
IPC: G11B15/467
Filed: 1984-02-17
Abstract: PURPOSE:To discriminate a recording speed by detecting an envelope of the reproduced output of a rotary magnetic head in the state where a magnetic tape is run at a prescribed speed at a reproducing start time and shaping the waveform of the detection output and measuring the period of one level of the shaped output with a timer. CONSTITUTION:When a reproducing key is operated, a control circuit 28 generates a reset pulse P1 to reset a flip-flop 29. A Q' output of the flip-flop 29 goes to the high level, and the control circuit 28 controls a motor driving amplifier 26 so that the tape running speed coincides with the LP mode. When data is recorded on a magnetic tape 1 in the LP mode, a counter 34 does not count FG pulses P3 at all. When data is recorded on the magnetic tape 1 in the SP mode, the counter 34 counts FG pulses P3 while pulses are in the low level. The envelope of the reproduced output of a pilot signal is detected, and the period of the low level is measured by the counter 34 to discriminate the recording speed.

Filed: 1978-03-15
Abstract: PURPOSE: To obtain arc with good stability as well as permit the control of current adaptable to various conditions by making welding using current capable of supplying the pulse strain of high frequency pulse current interrupted by comparatively low frequency.  
     CONSTITUTION: When the RS vice table element 21 is set, the pulse of the high frequency pulse oscillator 11 passes through the AND circuit 13 and is then counted at the preset counter 18. When the counted value reaches a set value, an output pulse is sent out to reset the RS vice table element. Thus, the output pulse of the oscillator 11 is applied to the preset counter 17, and when the counted value reaches a set value, the element 21 is again set. The RS vice table element 22 also sends out on output signal likewise, but the output pulse becomes lower in frequency because the divider 23 is provided. By setting up freely the output pulse frequency and duty factor of the two elements 22 and 21, wide range welding is performed.

Filed: 1990-02-08
Abstract: PURPOSE: To make heat transfer of a heat transfer tube excellent, to decrease contamination of the inside face of the heat transfer tube and to enable to evaporate main components of the feed stream in the upstream side of the inlet of a vacuum distillation tower by increasing an inner diameter of the heat transfer tube and an inner diameter of a connecting conduit by respective specific values along the lengths. CONSTITUTION: The inner diameter of the heat transfer tube 27 of the heating furnace 2 increases by 2.4-3 times the inner diameter of the tube inlet 28, and also the inner diameter of a connecting conduit 3 to the vacuum distillation tower 1 increases by 2.5-5.4 times the inner diameter of the tube outlet 29 along the lengths in the directions of the flows of respective fluids. Thus, a portion of the feed stream evaporates in the heat transfer tube 27 but since a liquid portion is always present on in the heat transfer tube 27, and excellent heat transfer is surely performed between the inner face of the heat transfer tube 27 and the feed, hot spots on the inner wall surface of the heat transfer tube 27 decrease and portions changing the feed stream to cokes decrease, then a contamination quantity decreases.  Also while the inner diameter of the connected tube 3 gradually increases, a liquid portion of the feed is evaporated in the connecting conduit 3, then a large volume of the feed stream becomes vapor.
