Title: Tension mechanism for ink film in thermal transfer recorder
Inventor: MOGI MURATO
IPC: B41J33/24
Filed: 1981-09-11
Abstract: PURPOSE:To prevent the slackening of film even at the time of stoppage of transfer operation by making the tension of a weight provided on the winding side for giving a tension to an ink film smaller than the braking force of a brake device provided to a film supplier. CONSTITUTION:An ink film 12 wound around a supply reel 10 is sent out by a greater winding force F1 of a winding reel 11 than the braking force F2 of the brake device 14 of the supply reel 10, passed through a guide roller 7 between a platen 6 and a thermal head 5, and then wound around a winding reel 12 through guide rollers 8 and 12, during which period a tension F3 for separating a recording paper 9 form the weight 13 is given. When the winding operation of the winding reel 11 is stopped, the tension force F3 of the weight 13 is given to the film 12 since the winding reel 11 does not turn reversely due to the presence of a reverse turning preventer 15 and the supply reel 10 is restrained due to a greater braking force F2 than the tension F3 of the weight 13.

Title: Magneto-resistance effect type head
Inventor: YAGYU SHINGO
IPC: G11B5/39
Filed: 1993-05-24
Abstract: PURPOSE:To well improve a yield and quality by preventing the variation in the characteristics of the magneto-resistance effect type head without degrading reproduction sensitivity. CONSTITUTION:A separating layer 52 consisting of SiO2, etc., is formed between an MR film 10 and a diaferromagnetic film 56 in the part of a track 16. The influence of the exchange bonding strength of the diaferromagnetic film 56 on the MR film 10 is lessened in the track part, by which the degradation in the reproduction sensitivity is prevented. The diaferromagnetic film 56 is formed as a continuous surface on the main surface. The current flows into the diaferromagnetic film 56 as well together with the MR film 10 when a driving voltage is impressed between conductive films 14. The bias magnetic field in the depth direction of the plane of Fig. is then formed and the impression of the magnetic field on the MR film 10 is possible. As a result, the common use of the diaferromagnetic film 56 as a bias layer is possible and the number of stages for separately forming the bias layer is decreased.

Title: Double vacuum cup
Inventor: OKUMA SHINOBU
IPC: B25J15/06
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To convey perforated panels more surely and efficiently. SOLUTION: In a double vacuum cup 11, making a large cup 12 and a small cup 13 consisting of an elastic body each adhere to a panel 7, and inhaling air in a gap between both these large and small cups 12 and 13, an end edge part 13a of the small cup 13 is bent in the inner diametral direction. With this, when the vacuum cup 11 is attached to the panel 7 by suction, such strength as preventing the end edge part 13a of the small cup 13 from being diametrally expanded is provided for this vacuum cup 11. In succession, any reduction in a suction area (value having deducted the area covered with the small cut from the area covered with the large cup) due to the diametral expansion of the small cup 13 is obviated, securing a necessary suction area. Since suction force in this double vacuum cup is proportioned to the size of this suction area, any reduction in the suction force due to deformation in these large and small cups 12 and 13 in time of being drawn in by suction is prevented from occurring, and thus the perforated panel 7 is stably kept up.

Title: Super-mini gas sensor
Inventor: IKEGAWA KOICHI
IPC: H05K3/46
Filed: 1987-06-10
Abstract: PURPOSE:To achieve a super-mini application of a gas sensor, by arranging a light waveguide, a radar diode for generating measuring and reference beams, a light combining filter, a photodiode and a microcomputer. CONSTITUTION:A microcomputer 6 outputs an emission signal and emits a measuring beam with the wavelength absorbed by methane from a laser diode 4A and subsequently, a reference with the wavelength in noway absorbed thereby from a laser diode 4B. Both the beams are combined with a light combining filter 4C to enter a waveguide path 3 at an incident port 3A. In the process of propagation, an evanescent wave generated outside a waveguide substrate is attenuated being absorbed by methane. Thus, a measuring light emitted at an emission port 3B and received with a photodiode 5 is given in the quantity of light as subjected to absorption corresponding to the density of a methane gas. The reference beam is received being little attenuated as in no way absorbed by methane. A computer 6 computes the density of a gas by a specified formula from an electric signal corresponding to the amount of measurement and the reception of the reference beam.

Filed: 1991-06-17
Abstract: PURPOSE:To provide a thermal line printer wherein twine of recording papers around the outer periphery of a platen roller at delivery can be prevented. CONSTITUTION:A twine preventive member consisting of a plate 7a having an end fixed to a printer body and a resin sheet 7b arranged so as to contact to a platen roller 3 at an end thereof is used. As a result, the forms of the plate 7a and the resin sheet 7b change with elasticity when a recording paper at delivery gets jammed between the platen roller 3 and the resin sheet 7b so as to give load to the platen roller 3. Accordingly, a step-out occurs at the time that the recording paper at delivery gets jammed due to the load to be generated by the twine preventive member, so that twine of the recording paper around the outer periphery of the platen roller can be prevented.

Abstract: PURPOSE:To decrease the contents of Ca and to improve grinding efficiency by vacuum-separating an unreacted reducing agent in a specific temp. range then grinding the resulted product of reaction obtd. by mixing and reduction diffusing of raw material powders in a process for subjecting the above- mentioned product to grinding, cleaning, dehydrating, and vacuum drying. CONSTITUTION:The resulted product of reaction obtd. by mixing and reduction diffusing of the raw material powders is ground after the unreacted reducing agent is vacuum-separated at 800-1100 deg.C. This vacuum sepn. operation is executed at 800-1100 deg.C and 10<-1>-10<-2> Torr vacuum degree. The above-mentioned temp. is more preferably set at above 838 deg.C which is the m. p. of Ca and is further preferably set at <=1000 deg.C in order to decrease the evaporation loss of the rare earth metal. The content of Ca in the resulted product of reaction subjected to this vacuum sepn. treatment decreases and, therefore, the grinding of the product is facilitated and the product is quickly ground to fine grains.

Title: Method for simultaneously measuring temperature and emissivity in high temperature furnace
Inventor: WATANABE KUNITOSHI
IPC: G01J5/00
Filed: 1989-06-07
Abstract: PURPOSE:To measure temperature and emissivity at the same time without using a water cooled shielding plate as a countermeasure for background light noises by providing a window having the required size in a furnace wall in the facing direction of a mirror surface. CONSTITUTION:A radiometer 31 is provided so that the normal line to an object to be measured 33 agrees with an incident axis. A window 34 is provided in a furnace wall. The size of the window is the size including a solid angle dOMEGA of reflected light from a copper plate. At this time, background light noises which are inputted into the radiometer 31 can be disregarded. That is, since the temperature outside the furnace is lower than that of a steel plate by several 100 deg.C, the energy of the background light noises becomes negligibly small. For example, when the temperature of the plate is 1,000 deg.C, the temperature of a known radiation source is about 630 deg.C, and S/N is 100. As the practical radiation source, the furnace wall itself is used as the radiation source. Fortunately, carbon fiber 35 has very high emissivity. Therefore, the fiber is stuck to the furnace wall, and the surface temperature is measured with a thermocouple 36. The temperature is used as the known radiation source. Then, the radiation luminance in a specified expression is detected with the radiometer 32.
