Title: Magnetic recording system
Inventor: SUZUKI KEIJI
IPC: G11B5/02
Filed: 1983-01-24
Abstract: PURPOSE:To decrease crosstalks and to improve recording density by setting the relative azimuth angles between the adjacent tracks of the plural recording tracks formed in parallel in the longitudinal direction of a magnetic recording tape in a 3-20 deg. range. CONSTITUTION:Plural recording tracks are formed in parallel with the longitudinal direction of a magnetic recording tape 1. In the figure, the direction of the gaps of a head for recording in the 1st, 3rd, 5th recording tracks 4a from above is inclined to the left as shown in the figure and the direction of the gap of the head for recording in the 2nd, 4th recording tracks 4b is inclined to the right as shown in the figure. The mutual azimuth angles are set at 3-20 deg.. Thus, the crosstalks between the adjacent tracks are decreased, the need for the gaps between the tracks is eliminated, and recording density is improved.

Title: Method and device for correcting measurement error of infrared thickness gage
Inventor: IGUCHI KATSUHIRO
IPC: G01B11/06
Filed: 1983-01-27
Abstract: PURPOSE:To correct a measurement error with high accuracy by subtracting the detection signal for the IR irradiating component to be irradiated from a measuring object from the detection signals for the measuring wavelength and reference wavelength transmitted through the object to be measured, and performing logarithmic ratio calculation. CONSTITUTION:The light emitted from a light source 18 passes a rotary chopper 20, and the light for measuring wavelength and reference wavelength transmitted through said chopper and the IR component when the light is shut off by a light shielding part are detected through a film 16 to be measured in a photodetector 12. The outputs IM, IR and I3 are held via a signal distributing circuit 42 in holders 30, 32 and 44, 46. Subtractions (IM-I3), (IR-I3) are made in arithmetic circuits 48, 50 and the ratio between both subtracted values are logarithmically calculated in an arithmetic circuit 36 for logarithmic ratio. The thickness of the film 16 is calculated in an output processing circuit 38. The measurement error occuring in the IR light released from the sample is thus easily corrected with high accuracy.

Filed: 1990-01-20
Abstract: PURPOSE:To obtain the functional characteristics of a stable electromagnetic valve hard to allow the formation of a magnetic deposit in a gap between a plate and a fixed magnetic core by providing a projection on a bobbin for preventing the deposition and accumulation of a magnetic impurity at the aforesaid gap. CONSTITUTION:The function of allowing and stopping the flow of a control fluid from an input port 12 to a discharge port 13 via the energization and deenergization of an electromagnetic coil 8, is the same as in the conventional electromagnetic valve. As the projection 17 of a bobbin 7 is formed in a gap between a plate 2 and a fixed magnetic core 4, however, no magnetic impurity is deposited and magnetic flux through a ball valve 3 is not so reduced as to stop the motion of the ball valve 3, different from the conventional electromagnetic valve, even if a control fluid flows from the input port 12 to the gap between the plate 2 and the fixed magnetic core 4, and further a magnetic impurity is carried on the fluid flow. According to the aforesaid construction, the operational function of the ball valve 3 fro the electromagnetic coil 8 is not impaired, regardless of the long service of an electromagnetic valve and the stable functional characteristics thereof can be obtained.

Title: Thermal recording apparatus
Inventor: NISHIKAWA MASAHARU
IPC: B41J2/38
Filed: 1987-01-20
Abstract: PURPOSE:To prevent the generation of dew condensation, by controlling the supply of a current to a thermo-module on the basis of the output of a sensor for detecting the temp. of a substrate having the heat generating element of a thermal head arranged thereto and the output of a sensor for detecting the temp. in an apparatus so as to make the temp. in the apparatus approximate to that of the substrate. CONSTITUTION:The supply of a current to a thermo-module 32 is controlled by a control circuit 34 so that the temp. of a substrate becomes almost equal to that in an apparatus. When the driving of a recording apparatus is started and the heat generating element 30 of a thermal head 20 generates heat, a part of said heat is lost by recording and the remainder thereof heats the substrate 28. The output of a temp. sensor 36 detecting the temp. of the substrate is compared with that of a sensor 37 detecting the temp. in the apparatus and, when the rising in the temp. of the substrate 28 is shown, the supply of a current to the thermo-module 32 is started by the control circuit 34 and the substrate 28 is cooled to the temp. in the apparatus. The opposite side surface of the thermo-module 32 is heated to temp. higher than that in the apparatus, but the heat is radiated by fins 32 to cool said surface. Since said cooling effect can be continued at a high level until the temp. of the substrate 28 reaches that in the apparatus, the rising in the temp. of the substrate 28 generated by the driving of the heat generating element 30 is rapidly and certainly prevented.

Title: Estimating method for life of metal material
Inventor: SHIYOUJI MORITAKA
IPC: G01N23/207
Filed: 1982-01-29
Abstract: PURPOSE:To estimate a life when a fatigue and a creep are overlapped with each other, by a method wherein a fatigue damage is detected using an X-ray half-value width, and a creep damage is detected using an electric resistance. CONSTITUTION:In the case of, for example, an annealing material, a half-value width in a process of fatigue is fast in an increase speed in order from a high stress ampltude, but by reference to a correlation between the half-value and ratio N/Nf of a repeating number Nf of breaking to a repeated number N of stresses, it has uneveness being to the degree indicated in shaded lines, but it can be shown in approx. a single line. A master curve of a change in the half- value width is previously prepared, the repeating number N of the stresses is recorded to measure the change in the half-value width, and this estimates a remaining life. Estimation of a life by a damage due to a creep is such that a change in a resistance rate depends upon a carbide reaction of a material, and a carbide reaction is correlative to a creep deformation amount, whereby a relation curve between them is previously formed, creep time is recorded, and a current electric resistance is measured to estimate a remaining life.

Filed: 1993-01-28
Abstract: PURPOSE:To accurately decide the position and shape of even an electronic component which has a lead edge except in a nearly rectangle shape by recognizing the continuity of the lead edge. CONSTITUTION:Image data are read out of a camera 5 and store in a memory 62 and then process windows are set for the respective sides of a lead. Then the edges of the leads begin to be detected, window by window, and the detected edges are labeled. Here, once an edge is detected, the detected coordinate values and label data before and after the corresponding address in the memory are referred to. If pixels corresponding to the offset (n) of a label memory are read in, a label position is written into the position of a pixel whose edge is currently detected on condition that the label is present within a range of offset n+ or -m and in a range of n+ or -1. When the label is not present within the range of n+ or -1, the label position is not rewritten. Consequently, the continuity of a line is prevented from being disordered owing to a noise pixel, etc.
