Title: Terminating circuit
Inventor: MATSUI MASAHIRO
IPC: G01R31/28
Filed: 1983-05-16
Abstract: PURPOSE:To open or close a switching circuit according to whether a terminating resistance is necessary or not by connecting a primary coil which has the switching circuit on a secondary coil side to the receiving terminal side of the connection cable of a package tester. CONSTITUTION:When a printed board package 1a to which the terminating resistance 3 is connected is tested, the contact SW of the switching circuit 4 of the printed board package tester 2 is made to form a short circuit, and consequently the terminating resistance of the primary coil L is regarded as a zero-ohm line, excluding the terminating resistance. When a printed board package 1b having no terminating resistance is tested, the contact SW is broken to form an open circuit, so the L1 serves as the terminating resistance. Therefore, the need to discriminate between TTL and CML is eliminated and the trouble of the replacement of the package tester is eliminated.

Title: Mold clamping mechanism for injection molding machine
Inventor: ICHIHARA TOSHIAKI
IPC: B29C33/22
Filed: 1995-03-20
Abstract: PURPOSE: To prevent the deflection of a stationary platen from being generated due to the use of a mold having a small mounting area even if the thickness of the platen is not increased by mounting the platen at a tie bar via a supporting mechanism fixed to the end of the bar. CONSTITUTION: A truncated quadrangular pyramidal supporting mechanism 10 is a stress sheath mechanism in which a second dynamic element E2" is included in plane at the oblique surface of the mechanism 10. At the time of clamping a mold 6, the mold clamping force f1 which is operated at a stationary platen 1 via the mold 6 is decomposed to a force f1 which is operated along a second element E2 at each die bar 2. The operating line of the force f2 is formed at an angle with the plane of the platen 1 to coincide with the direction of the element E2 at each bar 2 to connect the center P1 of the platen 1 to the end 2a of the bar 2, and hence the element E2 receives only a compressive stress, but does not receive a bending moment. Accordingly the size and the shape of the element E2 are maintained.

Title: Disposal of waste water containing fluorine and dithionic acid
Inventor: HATANAKA KOUICHI
IPC: C02F1/58
Filed: 1980-06-26
Abstract: PURPOSE: To accelerate the precipitation of calcium fluoride crystal and to prevent the column from clogging during disposal of waste water containing fluorine and dithionic acid, by adding calcium sulfate into the waste water in a fluorine-removing step.  
     CONSTITUTION: In the disposal of waste water containing fluorine and dithionic acid, e.g. waste water used in desulfurization of exhaust gas from an exclusive coal-burning boiler, fluorine is coagulated and precipitated with a calcium compound at first and then with an aluminum salt, and removed from the waste water. At a desired stage in this process, calcium sulfate is added to the waste water. The calcium sulfate accelerates the precipitation of crystals, and the crystals are no longer precipitated thereafter. Consequently, an impediment to water flow can be inhibited in the disposal of dithionic acid using an ion exchange resin.
