Title: Working method of scroll lap and working device therefor
Inventor: YAMANAKA TOSHIO
IPC: B23C3/32
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To accurately judge the thickness of a scroll lap by extracting not only a deviation on a shape but also a deviation on a dimension, and to adjust a working device on abrasion of a tool by collectively converting a measuring coordinate point sequence of an outer line and an inner line into coordinates. SOLUTION: When abrasion of a tool used for work proceeds, a diameter of the tool reduces, causing a scroll lap becoming thick, reduction in a radius of the tool can be seized as an average of a thickness deviation. An average ΔT of this thickness deviation is determined by expressions I to III, and is set as an average thickness. Data on the tool diameter of a working device or data on a tool offset or data on a tool locus is corrected in the direction for eliminating the average thickness ΔT. ΔSm' and ΔUi' are a deviation ΔSm' and ΔUi' of a measuring coordinate point and a design value, respectively.

Title: Digital video signal processing circuit
Inventor: ABE HIROTOSHI
IPC: H04N5/45
Filed: 1989-11-08
Abstract: PURPOSE:To display a 2nd video signal with the same degree of picture quality as that of a 1st video signal by converting the 2nd video signal superimposed on the 1st video signal into a digital signal in a full range and applying DC shift and peaking processing to a portion corresponding to the 1st video signal after the superimposition. CONSTITUTION:When an area signal Sa is at a low level, an input component of a DCS circuit 19 is a master pattern signal component, a fixed data C is sent to an adder 21 while passing through a NAND gate circuit 23 and the data C is subtracted from an input digital picture signal DIN. When the area signal is at a high level, an input component of the DCS circuit 19 is a slave pattern signal component and the fixed data C cannot pass through the NAND gate circuit 23. Thus, when the signal Sa is at a high level, the input digital picture signal DIN passes as it is through the adder 21 and becomes an output signal DOUT. Thus, DC shift is applied to only the master pattern video signal portion. Then the full range of the dynamic range is obtained from the 2nd video signal input.

Title: Magnetic recording and reproducing device
Inventor: HIROHATA NAOTO
IPC: G11B5/027
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To obtain helical scanning record by a first and a second rotary magnetic head with a magnetic gap for which the azimuth angle is set at 90 degrees or less clockwise and counterclockwise, respectively, for the width direction of a recorded trace. SOLUTION: A first and a second rotary magnetic head are rotated for a specific number of and in a specific direction of revolution as preliminarily determined. The travelling direction of a magnetic tape, which runs in a state wound on a part of the circumferential surface of a drum consisting of an upper and lower drums, is switched successively and alternately in the forward and backward directions, with recording performed back and forth continuously. In this case, with the number of times counter for the change in the travelling direction of the tape, the magnetic tape running in the forward or backward directions is made to face alternately with the rotary locus of the first and the second rotary magnetic head.  Since one or the other mode for magnetic recording operation is applied, record is formed by a rotary magnetic head having a magnetic gap of an azimuth angle in which two adjacently formed recorded traces are different from each other.

Then plural dot electrodes provided near the rough position of the point P are successively selected and the distances between these electrodes and the point P are calculated. Thus the accurate position of the point P is obtained.

Title: Space heating device
Inventor: NAGANUMA HISAO
IPC: F24H6/00
Filed: 1987-11-18
Abstract: PURPOSE:To prevent the conspicuous lowering of a discharge gas temperature and to prevent dew condensation in the exhaust gas, by a method wherein a heat exchanger is situated on the surrounding part of a combustion gas flow passage running between a burner and a heat-ray radiating cylinder. CONSTITUTION:A heat exchanger 20 for floor heating is situated to the upper part of a combustion chamber 17, forming a combustion flow passage, togetherwith an ignition plug and a flame rod. The combustion chamber 17 is communicated to a chimney connection port D through a heat resistant glass cylinder B, having a heat radiation cylinder A, and an exhaust hood C. The heat exchanger 20 for floor heating is positioned to the surrounding part of the combustion chamber 17 forming the combustion flow passage. Since it absorbs heat radiated from a combustion flame to an outer periphery, the wall temperature of the combustion chamber 17 is lowered, an amount of heat dissipated from the combustion chamber 17 to the outside can be decreased, and floor heating can be effected without extremely decreasing a discharge gas temperature. This constitution enables sharp decrease of an discharge gas temperature by means of floor heating, and prevention of the occurrence of dew condensation in a chimney.
