Abstract: PURPOSE: To efficiently recover the vapors of a washing mixture by gathering the vapor released parts from the respective releasing sections of an apparatus for continuously executing org. pickling of cast copper and successively treating these parts by a centrifugal fan, heat exchanger, condenser column and furnace.  
     CONSTITUTION: The vapors of varying velocities of the cooling and washing mixture recovered at the respective releasing points 21 to 21E of the continuous casting apparatus for copper are sent via stainless steel pipes 22 to 22E to the centrifugal fan 24. The vapors are kept at about 80.3°C and pressure of about 1.4 atm and are introduced at 518.2 to 548.6m/min velocities to the heat exchanger 26. In this heat exchanger, the temp. of the vapors is lowered down to about 12.8°C and the vapor/liquid mixture is introduced via a pipe F to the condenser column 27. The velocity thereof is lowered down to about 71.63m/min and the floating liquid drops are separated from the vapor flow. The liquid drops are then sent via a pipe 22G to cooling and washing stages and are recycled. The remaining vapors are introduced via a pipe 22L at a velocity of about 792.5m/min into the furnace 22 where the remaining org. materials are completely oxidized.

Filed: 1987-12-04
Abstract: PURPOSE:To increase the number of times capable of photographing serially without increasing the conventional capacity of a memory by providing a memory area designating means, etc., to rotate the designation of memory areas for the set number of frames. CONSTITUTION:A memory area number designating circuit 6 sets the number of memory areas to rotate in accordance with the input of switches 21-23 and a memory area designating means 8 designates a memory area number in accordance with the output. A memory address output circuit 9 outputs an address in a memory 3 by the output of the circuit 8. That is, a picture for one frame generated from an A/D converter 2 at the time of terminating a first photographing is recorded in an area M1 in the memory 3 and it is recorded in an area M2 in a second photographing. When a Kth photographing is terminated, recordings are successively executed in areas M1-MK and when a (K+1)th photographing is executed, the recording is executed in the area M1 again. Thus, by providing the means 8 and rotating the areas, the number of times capable of photographing serially can be increased without increasing the capacity of the memory.

Abstract: PURPOSE: To prevent microcracks from being generated due to low pressure by applying a pressure of less than a prescribed value to a laminated material, heating the material in a state where the pressure is applied, at least partially vulcanizing the material, and forming a laminated board. CONSTITUTION: This multilayer printed wiring board is obtained by laminating the alternate layers of the core material of ester cyanate and the prepreg material of the ester cyanate by pressing. For instance, in the case of vulcanizing the laminated board by adding the heat from the standard processing temperature of 180 deg.C, a vulcanizing pressure is less than 156 psi and is preferably 75 psi. Then, incomplete vulcanization is performed by lamination process, and post-calcination process is performed at the temperature of about 220 deg.C, without applying the pressure so as to complete the vulcanization.

Title: Infra-red ray detector
Inventor: HIKITA SOICHIRO
IPC: H01L31/10
Filed: 1987-12-04
Abstract: PURPOSE:To separate elements securely between diodes by forming a crystal layer having an energy gap greater than that of a crystal layer for forming elements between a crystal layer for forming an element and a substrate and by forming a photodiode into a mesa type. CONSTITUTION:Since if infrared rays are introduced from the bottom of a substrate 11, a crystal layer 12 absorbs light of wavelength of 5mum band or less and it is penetrated with light of wavelength of 5mum band or more, light of wavelength of 5mum of less is absorbed in the crystal layer 12, and photo- electrically converted to a carrier. On the other hand, light of wavelength of 5mum or more penetrates the crystal layer 12, reaching a crystal layer 13. Since the crystal layer 13 absorbs light of less than 10mum band, light of wavelength of 5-10mum is photo-electrically converted in the crystal layer 13 to become a carrier. It reaches a P-N junction 17 and is detected by a photodiode 18. A carrier photo-electrically converted in this crystal layer 13 will not generate a crosstalk because the photodiode 18 is element-separated securely in a mesa form. Since a band barrier is formed with a buffer layer, minority carriers produced in the crystal layer 13 will not flow to neighboring image cells through the buffer layer.

Abstract: PURPOSE:To improve the rate of erasure and jitter characteristics by forming a laminated body consisting of at least a transparent substrate, a 1st dielectric layer, a recording layer, a 2nd dielectric layer, a high refractive index layer and a light absorbing layer. CONSTITUTION:In this optical recording medium, the quantity of light absorbed in the recording layer in an amorphous state is reduced and can be made equal to or larger than that in a crystalline state by newly disposing a laminated part consisting of a high refractive index layer and a light absorbing layer in place of the conventional reflecting layer. As a result, difference in temp. rise at the time of recording is reduced, the deformation of recording marks and a shift of formation positions can be suppressed and erasing characteristics and jitter characteristics can be imporved. Even after recording and erasure are repeated many times, action is stable and the deterioration of the characteristics and the occurrence of defects are hardly caused.

Title: Transformer for high-frequency heater
Inventor: NAKAMURA MASAMI
IPC: H01J23/34
Filed: 1989-11-28
Abstract: PURPOSE:To provide a small and light-weight transformer by making a narrow gap at a main leg for a high-voltage winding and an input winding and a wider gap at a branch leg forming a magnetic feedback circuit. CONSTITUTION:There are provided gaps in a transformer core, a wide gap 6 at a branch leg 18 and a narrow gap 5 at a main leg 17. Since the gap 5 is narrower, leakage flux is smaller at the main leg 17, and thus closer coupling is possible between an input winding 1 and a high voltage winding 2. On the other hand, the leakage flux at the wider gap 6 is greater. Therefore, the leg 18 may be made thinner than the leg 17 to equalize the flux density at both legs; that is, it is possible to provide a small and light-weight transformer.
