Title: Low-softening phenylphenolaralkyl resin and epoxy resin composition containing the same
Inventor: URAGAMI TATSUNOBU
IPC: C08L63/00
Filed: 1996-05-13
Abstract: PURPOSE: To obtain an epoxy resin composition having good heat, impact, cracking and humidity resistances and workability by using a low-softening phenylphenolaralkyl resin as the curing agent component. CONSTITUTION: A low-softening phenylphenolaralkyl resin (A) comprising rating units represented by formula I (wherein X is a group of formula II), terminated with -X-H and having a softening point of 100 deg.C or below accounts for 10-100wt.% of the total curing agent component. The amount of A added to an epoxy resin is usually such that 0.5-1.5 equivalents of the active hydrogen atoms of the curing agent are present per equivalent of the epoxy groups of the epoxy resin. The component A is effective as a curing agent for all epoxy resins. The epoxy resin is not particularly limited so far as it is one having at least two epoxy groups in the molecule. This is prepared by reacting an aralkyl halide or an aralkyl alcohol derivative with a phenol compound in an amount more than three times larger than the number of moles of the former compound used in the presence of an acid catalyst.

Title: Equipment for received signal discrimination
Inventor: NARISAWA NOBUHIKO
IPC: G01R23/16
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To enable accurate pulse train classification and accurate discrimination in an environment where radar signals are complicated, by classifying pulse trains by using cross-spectrum as the Fourier transform of cross- correlation. SOLUTION: Sample data of each receiving pulse is subjected to complex Fourier transform by an FET processor 4, and peak frequencies and phases are sequentially accumulated in an FET buffer 5. A cross-spectrum processor 6 operates cross-spectrum (Fourier transform of cross-correlation) of the newest and the oldest FET data which are accumulated in the buffer 5. That is, the Fourier transform data of a present signal are compared with those of a part signal. When the peak frequencies are identical to each other, the phase difference Φ of the Fourier transform data of them at the peak frequency is obtained. Then a specified relation is held between the phase difference Φ and the arrival time difference τ. The arrival time difference τ is classified for each radiation source, and accumulated in an arrival time buffer 7.  Thereby, accurate pulse train classification is enabled.

Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To make cleaning easy and efficient by including an open/ close control means for opening respective hoppers according to a hopper open/close pattern stored in a cleaning open/pattern storage means. SOLUTION: When a cleaning mode is specified, a hopper open/close control means reads open/close pattern information stored in a cleaning open/close pattern storage means for advancing open/close control of each hopper by one step for each switch operation. When an operator continuously makes cleaning water flow onto each transfer trough 24, residual (w) depositing on the trough 24 or cleaning water drops into a pool hopper 25 and accumulates there. Then when a shutter 33 of the hopper 25 slides to open, the cleaning water in the hopper 25 drops into a weighing hopper 35 together with the residual (w) and temporarily accumulates there.  Similarly the residual (w) depositing in the hopper is also transferred together to a lower stage hopper sequentially, a timing hopper 50 at the lowest stage opens so that the cleaning water and the residual (w) is together exhausted to a conveyer, and thereafter similar operation is repeated.
