Title: Dental composition
Inventor: KOMURA IKUO
IPC: A61K6/00
Filed: 1988-07-13
Abstract: PURPOSE:To obtain a dental composition useful as a pretreatment agent or adhesive for tooth and/or dental material by dissolving a radically polymerizable monomer and an organic peroxide in a volatile tert-alcohol and filling the solution in a plastic container. CONSTITUTION:The objective dental composition is produced by dissolving 0.1-300 pts.wt. of a radically polymerizable monomer [preferably a (meth)acrylate monomer] and 0.01-10 pts.wt. of an organic peroxide (e.g., dibenzoyl peroxide) in 100 pts.wt. of a volatile tert-alcohol (e.g., t-butanol). The composition can be stored in a plastic container essentially without causing the evaporation loss of the solvent and the problem of the deterioration of property caused by the decomposition of the organic peroxide. Accordingly, said composition can be filled in a dripping-type plastic container having the form of an eyedropper to enable the application of the necessary amount of the composition to the surface of tooth, a dental material, etc.

Title: Assembling method for segment
Inventor: MIURA KIMIO
IPC: E21D11/38
Filed: 1994-07-04
Abstract: PURPOSE:To prevent the damage of a seal by sticking a lubricant containing a solid lubricant to the surface of a seal material, and specifying the grain size of the solid lubricant when a segment stuck with the seal material on a connection face is connected. CONSTITUTION:When a segment 2 stuck with a seal material 1 to improve watertightness is to be stuck, a lubricant containing a solid lubricant is stuck to the surface of the seal material 1 in advance. A single solid lubricant made of powder such as talc and a fluororesin or its water dispersion liquid is used for the lubricant. The solid lubricant is spherical powder of l-50mum, and nonhygroscopic one is preferable. Since the segment 2 is assembled with low inserting force, the damage of the seal material 1 can be reduced, it has a high static friction coefficient after it is assembled, the return of the segment 2 by the compression reaction of the seal material 1 is very little, and the assembling accuracy can be improved.

Title: High-speed switching circuit
Inventor: KISHIMOTO RYOZO
IPC: H04Q3/52
Filed: 1987-07-15
Abstract: PURPOSE:To improve the throughput with a high-speed switching circuit by dividing a Benes network into a distribution network (first half) and a routing network (second half) to distribute a input packet into the minimum value loads within the distribution network and monitoring the load of the middle unit switch of the Benes network to return the information on those loads to an input unit switch via a return signal line. CONSTITUTION:When a route is set for the packet which is newly inputted to a unit switch of the 0-th stage, the loads of two output terminals of said unit switch are compared with each other. In this case, the loads Q00 and Q01 connected to the output ports 1 and 2 are distributed at random as long as Q00=Q01 is satisfied and then outputted to the port 2 in the case of Q00>Q01 respectively. As a result, each unit switch always replaces the load information held presently by its follower connection unit switch. For the middle connection switch of a Benes network, '-1' is fed back to a unit switch of the 2nd stage as the load differential information on said connection switch when the packets are sent to a routing network. Thus the excellent throughput is obtained in terms of the average delay time characteristics, etc.

Title: Radiation detector
Inventor: BETSUPU TOSHIHIRO
IPC: G01T1/185
Filed: 1980-12-15
Abstract: PURPOSE:To suppress the output level range on the upper limit side and decrease the bit number necessary for indicating data number within the upper and lower limit range of output signals by using mixed gases of a rare gas and a gas forming negative ions as a packing gas. CONSTITUTION:In an ionization chamber type radiation detector of parallel flat plate type, its output electric current (i) is i=(1-1/6Xalpha/ek1k2Xqd<2>/V<2>)qd (where d: the spacing between electrode plates, V: applied voltage, e: the electric charge of electron, q: ionization density, alpha: a recombination constant, k1: the mobility of negative ion, k2: the mobility of positive ion). The device of this invention uses a mixture of a rare gas and a gas for forming negative ions, for example, gaseous nitrogen, as a gas to be packed into the radiation detector. In this case, the gas for forming negative ions generates negative ions in correspondence to the does of incident rays and therefore the amt. of their recombination with positive ions increases, thereby increasing the term of the recombination in the equation. Hence, as the ionization density (q) increases, the output current (i) deviates from a straight line and provides a non-linear output characteristic.
