Title: Surface-treated steel plate for can making having excellent seam weldability
Inventor: SAITOU TAKAO
IPC: C23C28/00
Filed: 1983-09-30
Abstract: PURPOSE:To provide a titled steel plate which reduces the amt. of Sn to by used by providing a coating layer consisting of an extremely slight amt. of a base alloy contg. P, Co, Fe, Cr, Zn, etc. on at least one surface of the steel plate and providing an Sn coating layer and chromate treating layer atop the same. CONSTITUTION:An Ni alloy consisting essentially of Ni and contg. about >=5% of >=1 kind among P, Co, Fe, Cr and Zr is plated on at least one surface of a steel plate subjected to surface cleaning and an Ni alloy coating layer is provided thereon at 2-30mg/m<2> per one surface. An Sn coating layer of about 200- 1,000mg/m<2> is provided atop said coating layer and further a chromate treating layer is provided atop the same to obtain the surface treated steel plate for can making having excellent seam weldability. Alloying of Sn with the base iron in the stage for baking the coated film is suppressed with the above-mentioned steel plate by the presence of an adequate amt. of the Ni alloy coating layer and about >=100mg/m<2> free Sn is assured to remain. Excellent seam weldability is thus obtd.

Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To provide a clean conveyor with slidable rollers, which is suitable for clean room-environment, and which can be easily assembled, and which can accommodate misalignment of components. SOLUTION: In order to convey articles, slidable rollers 52 are arranged on a roller shaft 50. The roller shaft 50 is driven by a chain 34 and sprokets 46, 48, or a belt and pulleys. These mechanisms are enclosed in an enclosure of the first enclosed space 29a with an assembled body consisting of panels, seals, supports, and thus granular materials generated from the mechanisms can be sealed. A two-parts structured elastic fixed type roller shaft seal makes up a sealing means between spool seal, a side panel 68, and a seal support 64 to hold the granular materials inside the enclosure, and to prevent air from entering the enclosure. The granular materials and the air are removed from the inside of the closure by discharge devices.

Title: Duct type ventilating air condition unit
Inventor: TSUKADA SEIICHI
IPC: F24F11/76
Filed: 1991-07-22
Abstract: PURPOSE:To facilitate adjustment of wind volume balance of respective rooms by providing a switch to set a damper moving range among remote control switches which are provided in living rooms, so that the wind balance of the respective rooms can be set arbitrarily. CONSTITUTION:First, in order to adjust the maximum opening degree in a damper moving range of a damper 113 of a duct 105 in which wind volume is very large, a damper opening degree setting switch 17 of a controller 11 is pushed at hand to make all dampers 112 and 113 open fully. In this state, every time a 'closing' side switch 21 of a damper opening degree adjusting switch 18 is pushed, the opening degree of the damper 113 gets smaller from its full opening state steppingly at a prescribed angle. An 'opening' side switch is used, on contrary, for increasing the opening degree steppingly at the prescribed angle. Thus, by changing the opening degree of the damper 113, blowing- off volume from a duct 105 into a room 109 is determined and compared with that of another room 108, so that substantially equal blowing-off volume in the both rooms can be obtained.

Title: Tapered waveguide type spot size converter and formation of its thin film
Inventor: KOKUBU YASUO
IPC: G02B6/122
Filed: 1989-07-13
Abstract: PURPOSE:To decrease insertion losses while maintaining the short length of a tapered part by aligning the position where the tapered part of the core having a high refractive index starts and the front end of the tapered part of the core having an intermediate refractive index and thereby uniformly changing the refractive index of the equiv. core. CONSTITUTION:A clad mode removing layer 2, a low refractive index glass clad layer 6, a high refractive index glass core layer 1 of a tapered opposite superposition type, an intermediate refractive index glass core layer 5 and a low refractive index glass clad layer 4 are successively laminated on a substrate 3. The two slab waveguides having the high refractive index glass clad layer 1 and the intermediate refractive index glass clad layer 5 are so formed as to face each other to largely vary the refractive index difference in the propagation direction of light between the cores 1.5 in the waveguide of the high refractive index glass core layer 1 having the small core thickness and the waveguide of the intermediate refractive index glass core layer 5 having the large core thickness and the clads 4, 6 having low refractive indexes, by which the arbitrary changing of the conversion rate of a spot size is permitted. The taper angle is diminished in this way and the lower loss is attained without increasing the length of the converter.

Title: Color image recording device
Inventor: OTA YUKIHISA
IPC: H04N1/46
Filed: 1988-07-20
Abstract: PURPOSE:To prevent the generation of granular noise in a high-light section and thereby make possible the visualization of a high-quality color image with superior gradation and resolution by quantizing each color image signal using an error diffusion method when a detected achromatic component exceeds a specified value. CONSTITUTION:Quantization is performed by an adder 6 and a comparative subtractor 8 using an error diffusion method. An output from a selection circuit 4 is entered into not only a comparator 5 but also the adder 6. In the adder 6, an error between input data which generates with previous pixels which are output from the comparative subtractor 8 and output data, and the density data of outstanding pixels are added together through the timing of clock pulse. After this, the data added together is output to the comparative subtractor 8. The comparative substractor 8 compares the output from the adder 6 as an input with a threshold value '80H' through the timing of clock pulse. If the input data value is larger than 80H, '1' is output to the selection circuit 11 by the comparative substractor 8, while if the input data value is smaller than or equal to 80H, '0' is output.
