Title: Working method of solid material
Inventor: YAMANOI HIROSHI
IPC: G02F1/01
Filed: 1983-09-30
Abstract: PURPOSE:To enable mass working of materials hard to be subjected to general machining process without causing distorsion and crack by coating said material with mask layer durable against a sandblast then ejecting fine grinding powder having mesh higher than specific level with specific ejecting pressure. CONSTITUTION:One surface of planar solid material 2 to be worked is coated with a mask layer 4 made of such material as having durability against a sandblast while having a mask pattern corresponding to the shape to be worked. Then fine grinding powder having mesh higher than 1,500 is ejected from above said mask layer 4 toward one face of solid material 2 with nozzle ejecting pressure of about 5kg/cm<2> or less when the distance between an ejection nozzle 6 and solid material is 50mm. to perform grinding. When working such material as having high cleavage and anisotropy thereby hard to work mechanically through this method, distorsion or crack will never produced in the crystal to be worked to provide high smoothness of surface while enable simultaneous working of plural works in short time.

IPC: H05K13/02
Filed: 1980-12-23
Abstract: PURPOSE: To prevent board materials from coming off in such a way that in a flexible board material carrying conveyor for printed circuit boards, rod bodies are provided, and they are arranged between conveying rollers with a stable angular tilt.  
     CONSTITUTION: The nature for the material to be used for rod bodies 8 is selected in consideration of durability and resistance to corrosion among synthetic resin, hemp fiber and metal. The rod bodies made of these selections are bridged over laminate inserting parts 8a between roll shafts 1. And a printed circuit board material 5 is tucked and conveyed by means of roll wheels 4 on both up and down sides to make turning movement. In this instance, even if spraying pressure or another tries to push off the printed circuit board material 5 in conveyance, to the verge of falling down or in sinuosities, they closely contact the rod bodies 8 and revert to the smooth conveying status.

Title: Electrification preventive synthetic resin floor material
Inventor: NAGATA HIDEYUKI
IPC: E04F15/16
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To improve the prevention of electrification by arranging a conductive paint layer or a conductive resin layer having surface resistivity of a prescribed range on a sheet-like base material and also an electrification preventive layer having prescribed volume resistivity on it, arranging a through hole in a sheet- like floor material, and inserting a conductive terminal into the through hole. SOLUTION: A layer corresponding to the walking surface is formed of an electrification preventive layer 2 having a volume resistivity value of 106 to 109 Ω. Since the thickness is 1.0 mm at the maximum, thickness directional volume resistivity becomes 1/2 or less of a normally used electrification preventive layer of 2 mm thick. Static electricity generated on the walking surface and static electricity electrified to the human body almost easily transfer to a conductive paint layer or a conductive resin layer 3 having low surface resistivity of a lower layer.  The static electricity transferred to the conductive paint layer 3 can escape to the earth by passing through a conductive terminal 5 arranged in a through hole by passing through the conductive paint layer or the conductive resin layer 3 having low surface resistivity to thus fulfill a sufficient electrification preventive effect without being influenced by a base material of a floor material and an adhesive.

Title: Reagent for blood analysis
Inventor: MATSUDA NOBUAKI
IPC: G01N33/50
Filed: 1983-09-29
Abstract: PURPOSE:To make it possible to perform three-peak fractional classification of an eosinophil, a monocyte, a lymphocyte and other components rapidly, simply and accurately, by combining two or three kinds of specific three kinds of org. ammonium salts as a hemolytic agent for counting a white corpuscle, and containing this combination and citric acid. CONSTITUTION:Citric acid is added to an aqueous solution which is prepared by dissolving two or three kinds of tetradecyltrimethylammonium bromide (MTAB), hexadecyltrimethylammonium chloride (CTAC) and dodecylmethylammonium chloride (LTAC) all of which are different in hemolytic capacity to a white corpuscle and capacity for contracting the white corpuscle in combination, to form an analytical reagent which is, in turn, used in blood analysis. In this case, it is pref. to use a diluent containing a borate buffer solution, ethylenediamine- tetraacetic acid and a compound represented by formula as preservatives for preventing slime formation in combination with this hemolytic reagent. By using this reagent, accurate peaks are obtained by using a usual automatic corpuscle counting apparatus as shown, for example, by the peak A of a normal white corpuscle, the peak B of an eosinophil and the peak C of the other.

Title: Fast breeder reactor
Inventor: MORIYA SHOICHI
IPC: G21C7/14
Filed: 1990-07-13
Abstract: PURPOSE:To prevent thermal striping due to the temperature difference generated at the lower part of a reactor core upper mechanism by forming coolant discharge ports on a control rod upper part guide tube, and enlarging the diameter of the guide tube up to above fuel assemblies. CONSTITUTION:Coolant discharge holes 25 are formed on a control rod upper part guide tube 18, and the diameter of the tube is enlarged up to above fuel assemblies 3 so that a part of coolant flowing out from the fuel assemblies 3 flows into the control rod upper part guide tube 18, and is mixed with coolant flowing out from a control rod lower part guide tube 5 to flow out from the coolant discharge holes 25. Thus, the coolant flowing out from the control rod lower part guide tube 5 becomes downflow, and does not turn the outside of the control rod upper part guide tube 18 to narrow down the region having large temperature fluctuations only to above the control rod lower part guide tube 5. Thermal striping generated at the lower part of a reactor core upper mechanism due to the temperature difference between the coolants flowing out from the control rod lower part guide tube and flowing out from the fuel assemblies can thus be prevented, and the reactor core upper mechanism can be kept sound.
