Filed: 1989-06-20
Abstract: PURPOSE:To provide a nearly constant amplification gain irrelevantly to the polarized state of a light signal by arranging a polarizing element which makes a 90 deg. polarization rotation between a 1st and a 2nd optical amplifier which differ in amplification gain. CONSTITUTION:Two optical amplifiers are used and arranged in series, and the polarizing element providing 90 deg. polarization rotation is interposed between them. Consequently, signal light L1 which is incident by its TE polarized wave to, for example, an optical amplifier 12A is provided with the TE gain GTE1 of the optical amplifier 12a, then whose polarization is rotated by 90 deg. through a 1/2-wavelength plate 13, so a TM polarized wave is made incident on a 2nd- stage optical amplifier 12a, then a TM gain GTM2 is provided, so that the total amplification gain comes to GT. When the signal light L1 is incident in TM mode on the optical amplifier 12a, on the other hand, the light is provided with the TE gain GTM1 by the optical amplifier 12a and the TM gain GTE2 by the optical amplifier 12b, so that the total gain is the same GT with the TE polarized wave input. The nearly constant gain GT is obtained by the amplifiers on the whole for an optional incident polarized wave.

Title: Measurement of styrene content in resin material sheet
Inventor: OKAZAKI YASUSHI
IPC: G01N21/552
Filed: 1988-06-23
Abstract: PURPOSE:To enable efficient measurement of a styrene content by determining absorbance of styrene from an amount of incoming infrared rays incident at one tilt end face of a prism put tight on the surface of a resin material sheet and an amount of outgoing infrared rays emitted at the other end face of the prism. CONSTITUTION:A lower end face 21d of a prism 21 is put tight on the surface of a synthetic resin material sheet 1 in transit while infrared rays with a wavelength of 14.3mum are radiated from an infrared rays generator 17. The, outgoing infrared rays emitted at a tilt end face 21b of the prism 21 being totally reflected within the prism 21 several times after being incident at a tilt end face 21a thereof are detected with a detector 16. In parallel with this, an amount I0 of incoming infrared rays is determined from current of a generator 17 and an amount I of outgoing infrared rays from a detection current of the detector 16 to obtain an absorbance by an expression of absorbance=log.I0/I. Then, based on the absorbance thus obtained, a content of styrene contained in the sheet 1 is determined from a characteristic of the styrene content previously determined.

Title: Image reader
Inventor: HASHIMOTO SHOZO
IPC: G06T3/00
Filed: 1987-06-23
Abstract: PURPOSE:To use memory storage capacity without any waste and to shorten a data processing time by storing only the data of the reading width of a necessary vertical line into a memory. CONSTITUTION:An image detecting part 1 synchronizes detected data with a signal clock for synchronization from a clock terminal and sends them from a data terminal. A data processing part 2 discriminates data outputted by the detecting part 1, executes serial-parallel-conversion into the data to be written into a memory 3, and transfer the data to the memory 3. The memory 3 stores the data transferred from the processing part 2. A vertical dot number designating circuit 4 transfers the reading width of a designated vertical line, namely, data up to a designated vertical dot number (m) to the memory 3 and sends to the processing part 2 a control signal to control so as not to transfer data (m+1-n, where (n) is the number of dots for one line) except for the designation to the memory 3. Thus, data to exceed the reading width of a necessary vertical line are eliminated.

Title: Method for judging cooling characteristic of cooling fin for heat exchanger
Inventor: YAMADA OSAMU
IPC: G01M99/00
Filed: 1982-09-09
Abstract: PURPOSE:To judge the cooling characteristic of a cooling fin simply and quickly, by judging the characteristic based on the amount of deviation on the outer surface of the cooling fin, which is caused by distortion of straight lines, being drawn on the surface of a strip plate material in the width direction in advance, caused by the fin molding. CONSTITUTION:Straight lines are drawn on the surface of a strip plate material 1 in the width direction by a marking needle for a specified length of the strip plate material one by one. Said material is rolled between two rollers 3 and 3 so that compressing rate is linearly changed in the width direction. Then a spiral shaped cooling fin 2 is formed, with the side having small compressing rate being inside. At the same time, the fin is wound around the outer surface of a heat transfer pipe 7 and a heat exchanger 6 is fabricated. The straight line is distorted and becomes a curve 4a at this molding. Based on the amount of deviation delta of the curve 4a on the outer surface of the cooling fin, the cooling performance of the cooling fin 2 for said specified length, with the curve 4a as a center, is judged.

Title: Magnetic head and its production
Inventor: ITO MASARU
IPC: G11B5/23
Filed: 1987-06-23
Abstract: PURPOSE: To eliminate the pseudo peak at the time of reproduction which is generated at the boundary between a magnetic metallic film and yoke by changing the magnetic characteristics of the magnetic metallic film facing a gap continuously in such a manner that the characteristics are poorer on the yoke side than the gap side.  
     CONSTITUTION: The yoke 1 consists of a magnetic oxide material such as Ni-Zn ferrite or Mn-Zn ferrite. The magnetic metallic film 3 consisting of Ni-Fe, Co-Zr, Fe-Al-Si, etc., is deposited on the surface of the yoke 1 facing the gap 2 for writing and reading out. The magnetic metallic film 3 is stuck on the yoke 1 by sputtering or vapor deposition and is thereafter joined to another yoke 1 while the gap 2 is formed by low melting glass. The magnetic characteristics of the magnetic metallic film are changed in the film thickness direction in this case. Namely, the excellent magnetic characteristics intrinsic to the material of the magnetic metallic film 3 are held intact in the part in contact with the gap 2 and the intrinsic magnetic characteristics are deteriorated in the part in contact with the yoke 1 so that said characteristics resemble to the magnetic characteristics of the material of the yoke 1. The generation of such a phenomenon as the pseudo gap at the edge is thereby obviated and the generation of the pseudo peak is prevented as well.

Title: Rolling method for steel material
Inventor: TSUBOTA KAZUYA
IPC: C21D8/00
Filed: 1981-10-01
Abstract: PURPOSE:To obtain steel materials of improved strength and toughness by subjecting raw materials repeatedly plural times to heating to above the Ac3 transformation point and rolling right above or right below the Ar3 transformation point at on-line state. CONSTITUTION:Heaters 4 and coolers 6 are installed at on-line state before and behind rolling mills 2. For example, in the case of alloy steel having 800 deg.C Ar3 transformation point, a slab heated above the Ac3 transformation point in a heating furnace is discharged from the furnace, is cooled down to 840 deg.C and is subjected to 1- several passes of rolling (black diagonal lines in the figure). Then in the coolers 6, the slab is cooled below the Ar3 transformation point to form the compsn. having prescribed ratios  of an alpha phase and the slab is subjected to 1- several passes of rolling. The rolled steel is heated above the Ac3 transformation point, that is, up to 840 deg.C and after this treatment is repeated >=1 time as shown, the slab is rolled. Here, the accumulation of working strains by the rolling in the unrecrystallized gamma area, the formation of working ferrite by the rolling in the two phase area (alpha+gamma), and the fining of crystal grains by the formation of the gamma alpha transformation in such a state are repeated. As a result, the steel plate of the nature provided with advantages of normalizing and controlled rolling  is obtained.

Title: Magnetic recording body carrier
Inventor: UCHIDA KOICHI
IPC: G11B17/34
Filed: 1987-06-25
Abstract: PURPOSE:To prevent write and read errors and paper jamming due to folding, shifting, etc., of a recording card by conveying the card to a prescribed position while making a magnetic detection part float, and bringing the card into contact with a magnetic detection part side. CONSTITUTION:When the recording card 2 is inserted into an entrance 32, a sensor 35 recognizes that and a stepping motor 36 begins to rotate. Consequently, the card is conveyed to the side of a sensor 40 by a rubber roller 37 through a belt 38. The roller 37 is slanted toward the magnetic detection part 41, so the card 2 moves along the side of the detection part 41. Further, its play is eliminated by a spring 42 and when the front end of the card 2 reaches a sensor 43, the motor 36 stops and a paper presser 44 is lowered to fix the card 2. Then the detection part 41 which floats at the position of a home position 45 moves toward an end point 46 while moving down to contact the magnetic stripe 3, writing or reading data. Consequently, errors and paper jamming due to the folding, etc., of the card 2 are precluded.

Filed: 1979-12-03
Abstract: PURPOSE: To realize an economical and assured lead-in inhibition action, by constituting the lead-in inhibition device of a tone arm in a purely mechanical way.  
     CONSTITUTION: In case the starting operation is given in the state under which no record disk 71 is put on the turntable 60, the table 60 starts rotations to fix the mobile fulcrum 54 of the rotary lever 52. At the same time, the major gear 6 starts rotations, and thus the driving component 10 slides to the right side from the left dead point. Thus the lever 52 works to shift the slider 53 to the right side. With this right movement of the component 10, the selection component 33 becomes movable to turn the reset plate 32 clockwise. When the component 10 reaches the right dead point, the lead-in latch 25 engages the carrier pin 23a. This engagement is released when the component 10 moves to the left side. In such constitution, an economical and assured lead-in inhibition is ensured.
