Abstract: PURPOSE:To improve appearance of a joint part of a side block and a roof block of a railway rolling stock, etc. CONSTITUTION:Joint of a side block 200 and a roof block 400 is carried out at a position of a gutter 415. A longitudial beam 201 of the side block 200 makes contact with the back surface of an outer plate 410 forming the gutter 415. The side block 200 with an interior member (for example, interior plate 230) installed on it and the roof block 400 with an interior member (for example, interior plate 420) are jointed by welding, etc., at the part of the gutter 415. For this joint means, a welding method which can be carried out only from outward is used. The longitudinal beam 201 fixed on the side block 200 and a coupler 201 are jointed on a lateral beam 402 of the roof block 400 with a rivet 500 on the interior side.

Filed: 1987-08-31
Abstract: PURPOSE:To obtain a single crystal rod having an oxygen concentration controlled at a prescribed level and free from deformation, suppressing the heat-radiation, in high productivity, by placing a funnel-shaped heat-insulation screen around a single crystal rod to be pulled up from a molten liquid and placing a specific quartz ring around the outer circumference of the screen. CONSTITUTION:The circumference of a crucible 2 containing a molten liquid 1 is surrounded, in such a manner as to enclose the growing single crystal rod 5 attached to a seed crystal 4, by a funnel-shaped heat-insulation screen 10 having a laminated structure composed of a heat-insulation material 11 having high porosity (e.g. carbon fiber) sandwiched with surface materials 12 such as graphite or SiC. The heat-insulation screen 10 is attached to the top of a graphite cylinder 13 lined with a heat-insulation felt 14. A quartz ring 15 is suspended from the center of the screen 10 and floated on the surface of the molten liquid 1. The quartz ring 15 is provided with an inner vertical wall 16 and an outer vertical wall 17 vertically extending from the outer periphery and the inner periphery. The surface of the molten liquid 1 is protected and the rate of evaporation of O2 is controlled by the quartz ring 15. The molten liquid 1 heated and melted with a heater 3 is pulled up to effect the growth of a single crystal rod 5, while suppressing the heat radiation with the screen 10, flowing down an inert gas flow 8, effectively excluding harmful gas and minimizing the temperature gradient in the molten liquid 1. A single crystal rod 5 having high quality can be produced by this process.

Title: Controller which can detect consumption of fluid containing particle
Inventor: JIMII DEII AREN
IPC: B01L3/00
Filed: 1992-08-18
Abstract: PURPOSE: To easily detect the exhaustion of a particlecontaining fluid by providing a photodetector positioned very closely to a capillary tube and a filter which can act on the photodetector. CONSTITUTION: When blood is applied to a sample reservoir 242, the blood immediately starts to flow through a capillary channel by a capillary action. The light from a light source 246 is scattered by red blood cells in the blood after the light is modulated by means of a modulator 248 and a small part of the light is guided through a capillary channel formed in a capillary flow device 250. The scattered light component is separated from the ambient light by means of a band-pass filter 256 and amplified by means of an amplifier 258. The signal of the amplifier 258 is rectified by means of a rectifier 260, integrated by means of an integrator 262, and generates a DC voltage which is proportional to the scatter light. As the reservoir 242 becomes empty due to the capillary flow, the optical patch between the light source 246 and a photodetector 252 is intercepted and the voltage output of the integrator 262 drops. When the output of the integrator 262 is connected to a comparator 264, a logical level indicating the presence/absence of the sample can be obtained.

The part 105 decides whether the 1st table data transformed into a structure overflows totally or partially out of a main memory part 103. An arithmetic part 110 performs the coupled arithmetic to the 2nd table data received from a table data memory part 104 via the part 109 based on said 1st table data and delivers this arithmetic result to an output part 111. In such a way, the coupled arithmetic is carried out at a high speed.
