Title: Digital signal transmitting system
Inventor: TAKAI HITOSHI
IPC: H04L1/02
Filed: 1985-12-26
Abstract: PURPOSE:To constitute a transmitting code excellent in a multi-path by dividing one time slot of data into the first half part and the last half part with a prescribed ratio and holding the phase transition in the prescribed direction between then in a BPSK signal. CONSTITUTION:One time of slot of data is divided into a first half part T1 and a last half part T2 and the phase transition is provided only at the prescribed angle in the constant direction between the first half part and the last half part. By the phase difference between the first half part of a certain time slot and the first half part after the (n) time slot only, and in the same way, a phase difference theta between last half parts each other, the information is transmitted. At the receiving side, a direct wave and a delaying wave are respectively delayed, detected and synthesized. Thus, since one kind of the diversity effect can be obtained, the code error ratio due to the multi-path can be significantly improved.

Abstract: PURPOSE:To enhance the yield of Si by feeding SiC which is obtained by allowing a by-product SiO to react with C in a side reaction chamber to the inside of an arc furnace in case of allowing carbon-base substance to react with SiC and silica rock in an arc furnace. CONSTITUTION:SiO2 blocks and carbon material are fed to the inside of a furnace body 10 from a hopper 16 for a raw material and SiO2 is allowed to react with C to produce Si while using arc A generated between an electrode 12 and lined graphite or a graphite crucible as a heat source and Si is collected on the bottom of the furnace and thereafter taken out. Large quantities of gaseous SiO are produced in the process of this reducing reaction and while these are passed through the layer packed with the raw material, the above- mentioned reaction is caused. One part of the gaseous SiO is passed through the layer packed with the raw material and introduced into a side reaction chamber 18. Carbon material is fed into the side reaction chamber 18 from the upper part and it is heated so that SiO is allowed to react with C and produced SiC is introduced into the furnace through a chute 22. By this method, SiO can be prevented from being scattered to the outside and the yield of Si is enhanced.

Abstract: PURPOSE:To make it possible to easily remove paper powders from a printing paper, and at the same time, to reproduce a first adhesion roller without washing, by providing a corona electrode immediately before the first adhesion roller and a second adhesion roller in contact with the first adhesion roller so that the electric charge loaded on paper powders adhered to the printing paper can be neutralized. CONSTITUTION:Electric charges loaded on paper powders 2 of a printing paper 1 are neutralized by corona discharge of a corona electrode 3, thereby weakening the adhesion force (static electricity) of the paper powders to the printing paper. Then, a layer of adhesives 5 of a first adhesion roller 4 is directly contacted with the printing paper 1, so that the paper powders 2 are adhered to the layer 5 and removed from on the printing paper 1. At this time, an adhesive layer 7 of a second adhesion roller 6 is in direct contact with the first adhesion roller 4 and therefore the paper powders 2' adhered onto the adhesive layer 5 of the first adhesion roller 4 are adhered to the adhesive layer 7 of the second roller 6. Thus, the paper powders 2' are removed from on the roller 4. As a result, the adhesive layer 5 of the first adhesion roller 4 can be reproduced without washing during the operation of the printing apparatus.

Filed: 1990-11-02
Abstract: PURPOSE:To achieve high speed processing with a simple control by starting seek of the next cylinder automatically when there is no instruction for stopping reading from an upper-level processing device even if reading of data from a final track of a cylinder is completed. CONSTITUTION:A magnetic disk device 9 starts reading from an instructed track to a buffer memory 6 and then transfers data from the memory 6 to an upper-level processing device 10. If the device 9 does not receive any instruction for stopping reading of a sequential data from a device 10 even if reading of data from a final track of a cylinder 1 is completed, it judges that it reads a next cylinder 1 continuously and then starts seek to a next cylinder automatically. When the device 9 completes seek, it starts operation for reading data from a first track of the cylinder to the memory 6, thus enabling reading to be processed at high speed with a simple control. Writing can also be speeded up in a similar configuration.

Abstract: PURPOSE:To detect an accurate crank angle to a top dead center by providing at least four protrusions at a preset angle at the position corresponding to the top dead center of a revolving element on a crank shaft and a top dead center sensor opposite thereto to measure an interval between pulses of sensor signals. CONSTITUTION:Four pulse generating protrusions 3 have the first protrusion 3a fitted nearly in position at 15 deg. to a top dead center, the second protrusion 3b at 5 deg. to the same, the third protrusion 3c at 5 deg. past the same and the fourth protrusion 3d at 15 deg. past the same. Pulses detected by a top dead center sensor 4 are fed to an arithmetic means 6. Pulse periodical data read by the counter 61 of the arithmetic means 6 are computed at a rotational speed in a CPU 62 by an arithmetic algorithm stored in a memory 63 and a crank angle to a top dead center is enumerated. It is thus possible to determine the angle of the first protrusion 3a to the top dead center. By such constitution that a preset crank angle is detected at which the revolving speed of a crank angle gets zero, adjustment and compensation are not necessary and a crank angle to the top dead center is detectable regardless of engine speed.

IPC: H04N19/85
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To realize the transmission system of compression data with less noise, low power consumption and fast response by controlling a period for decoding processing in response to the frequency of selection of a coding signal. SOLUTION: In the case of selecting and using a prescribed coding signal among plural coding signals received from a CCU section 1 via a transmission line 12, a control section 9 of a head section 2 detects a signal from an operation section 10 to activate a decoding section 7. Then in response to the frequency of selection of the coding signal to be selected, the period for decoding processing of the decoding section 7 is controlled. Thus, when the decoded signal is used with a high frequency of use, the decoding section 7 is operated continuously and when the decoded signal is used with a low frequency or not in use for a prescribed time consecutively, the operation of the decoding section 7 is stopped. Thus, the transmission system of compression data is realized with low power consumption, fast response and less noise production.
