Filed: 1989-02-23
Abstract: PURPOSE:To simplify dye having natural taste of gradation which cannot be obtained by machine-made paper such as coated art paper or the like by immersing the corners of folded Japanese paper with sublimated dye solution, and forming a flower patternlike design. CONSTITUTION:Japanese paper 11 which is employed as the material of a transfer sheet is folded in ridges along folding lines 12, and so folded as to form a triangular shape along folding lines 13. Three corners 14, 15, 16 of the folded triangular shape are immersed with suitable sublimated dye solution 17 to be colored. In this case, its pattern can be variable formed corresponding to the sublimed dye solutions of different colors or densities at the corners 14, 15, 16. Here, the oozing of the solution of the paper occurs from the corners of the triangular shape toward its center in response to the quantity of the solution to be immersed and the length of the period of time to be immersed thereby to form gradation pattern. Transfer sheet is transferred to cloth by a hot press similar to that of a conventional one.

Filed: 1990-02-27
Abstract: PURPOSE:To reduce an air pressure drop and to prevent the damage to catalyst in the catalytic production of sulfuric acid by using a converter in which a granular or annular catalyst is arranged in the preceding stage and a grid- shaped or honeycomb parallel gas flow-type catalyst in the succeeding stage. CONSTITUTION:A granular or annular catalyst is packed on the preceding tray of a converter 1 to form a catalyst bed (a).

Title: Dot printer head
Inventor: NORIKOSHI TAKASHI
IPC: B41J2/275
Filed: 1984-03-08
Abstract: PURPOSE:To arrange so that high-speed printing may be carried out by setting the gyrating fulcrum of an armature close to a core side through the minimization of a magnetic resistance between a protrusion of a yoke and the armature that was realized by fitting said protrusion into an opening on the armature. CONSTITUTION:Magnetic paths A, B are formed by the energization of a coil 15, an armature 18 is sucked into a core 16 and resultantly printing is carried out by a needle 11. At that time, a contact area between a yoke 14 and a hole 22 and a relative area between the pole 22 and an opening 21 on the armature 18 are large enough to minimize a magnetic resistance between the yoke 14 and the armature 18, even if an area S opposed to the base 17 of the yoke directly were small. Consequently, the l3 and further l1 can be minimized, thus enabling a clearance G between the core 16 and the armature 18 to be narrowed. In addition, the proportion of a distance l2 from a gyrating fulcrum 20 to the needle 11 to l1 is high and accordingly, the equivalent mass of the armature 18 can be reduced to make high-speed printing possible and save power consumption.

Title: Air contamination detecting device

Filed: 1978-04-15
Abstract: PURPOSE: To simplify the constitution of detecting device, by issuing an alarm through a signal generator by the detection signal of propane gas detecting sensor and the detection signal above the specified value of air contamination detecting sensor.  
     CONSTITUTION: When a reducing gas liable to diffuse is generated in the room and and the resistance of a gas sensor 1 made from metal oxide N type semiconductor or the like decreases, the outputs of voltage comparators 7 1  to 7 3  of a contamination display 3 to which diffrent reference voltages are applied by voltage dividing resistances R 3  to R 6  are sequentially inverted according to the degree of contamination. As a result, the degree of air contamination is displayed by display devices 8 1  to 8 3  of light emitting diodes or the like, and, at the same time, an alarm is issured by a buzzer 4 or the like by the signal generated from NAND circuit 5 through a change over switch 10. Similarly, a propane gas sensor 2 provided at a low place detects propane gas staying at a low place not detectable by the sensor 1 at a high place, then the circuit 5 generates a signal due to inverted output of the comparator 9 to issue an alarm. Thus, intended air contamination may be detected and notified in a simple constitution not requiring independent two detecting devices.

Filed: 1986-02-28
Abstract: PURPOSE:To correct an asymmetry potential with high accuracy without reducing the size of a measuring range by digitally storing the asymmetry potential and then converting the same to a voltage for correction. CONSTITUTION:The signal occurring in the asymmetry potential is outputted from a differentials amplifier 3 and an up-down counter 6 counts clock pulses when a switch 7 is turned on while only the asymmetry potential is generated by a standard soln. having a zero ion concn. the count content is converted by a D/A converter 8 and is inputted to the differential amplifier 1. The level of the output signal from the amplifier 1 begins to fall. The output from the amplifier 3 attains a zero level when the output voltage from the converter 8 coincides with the asymmetry potentials and therefore, a comparator 4 stops the outputting of the signal so that the counting operation of the counter 6 is interrupted. The amplifier 1 offsets the asymmetry potential signal by receiving the potentials signal from the converter 8 and the amplifier 3 outputs the potential difference signal occurring in only the ion concn. when a sample is measured after the switch 7 is turned off at this point of the time.
