Title: Mr inspection device
Inventor: ANDOREASU BICHIYURUN
IPC: A61B5/055
Filed: 1989-06-12
Abstract: PURPOSE: To develop an inspection device so as to perform inexpensive decoupling among coil systems placed orthogonally by structuring a circuit from a variable capacitor which can be interconnected among coil systems. CONSTITUTION: Orthogonally placed coils consist of a coil system 5 and 6 which slides by 90 deg. from each other. Each orthogonal coil system consists of two coils, coils 51, 52 and coils 61, 62 respectively, which slides by 180 deg. from each other. Each coil slides to orthogonal direction against the plain surface of the drawing, and consists of two conductive blocks which form an arc of approximately 120 deg. centering around a central axis 7 of a MR inspection devise. A capacitor 8 is connected between connecting points 523, 624 to the coils 52 and 62. The capacitor 8 generates current which flows to the reverse direction to rf current generated by combined coils, and therefore, at least offsets this current significantly.  The capacity required for the optimum decoupling by this capacitor is determined by connecting either the coil 52 or 62 to a rf generator, measuring the voltage induced to the other coil and changing the capacitor so as to make the voltage to be measured to minimal.

Title: Powdered grain addition treatment
Inventor: MURAKAMI IKUO
IPC: C02F3/12
Filed: 1978-12-02
Abstract: PURPOSE: To enhance the capability of sludge precipitation by depositing powdered grains to the sludge through the addition of easy-to-deposite powdered grains to active sludge.  
     CONSTITUTION: Powdered grains covered with hydrophobic material such as pitch grains, resin, and pitch is added to active sludge. Such powdered grains combine with functional gp. of part of the active sludge surface to the effect that when microbes combined with the hydrophobic material have come to the end of their life, newly growing microbes are allowed to combine with the hydrophobic material. As a result, once pitch powdered grains and hydrophobic powdered grains are added, frequent replenishment is unnecessary as long as the active sludge is not taken out.

Title: Q-switch solid-state laser oscillated by continuously excited
Inventor: WATABE SHUICHI
IPC: H01S3/11
Filed: 1988-06-20
Abstract: PURPOSE:To make it possible to detect failure of Q-switch operation by adding a detector to detect laser beams leaked from a total reflection mirror and a means to issue an alarm to the outside of the total reflection mirror. CONSTITUTION:Optical attenuator 26 is placed behind a total reflection mirror 11, and when there is leakage from the total reflection mirror 11 it attenuates it and inputs a signal to a gate circuit 24 through a detector 21. On the other hand, a timing circuit 18 receives a signal from a Q-switch driver 15 and inputs a comparator detection inhibition signal (b) into the gate circuit 24 and the comparator 20. This comparator 20 rings an alarm buzzer 17 by an output signal (e) and stops an excitation lamp power source 16 through an alarm circuit 19 only when a signal above level E set by a level adjuster 23 is input. Hereby, processing failure by the Q-switch operation failure is prevented.

Abstract: PURPOSE:To minimize a magnet by a structure wherein insulating spacers and flanges are reinforced without increasing eddycurrent loss. CONSTITUTION:Coils 1 and insulating spacers 2 both having holes at the center thereof are placed one above another alternately. Flanges 3,3 are placed at the top and bottom of thus laminated body, and bolts 4, 4 are inserted to obtain a unitized structure. Each coil 1 is wound round a bobbin 5. Each insulating spacer 2 is formed combinedly of an organic composite member 6 such as GFRP and a metal reinforcing member 7, and has radial grooves 8 formed in its upper and lower surfaces, thereby letting helium gas pass therethrough.

The partitioning line b extends in the direction to cross the concentric circle a of the insulating spacer 2, so that the line b becomes coincident with the groove 8. Since the magnetic path in the circumferential direction is interrupted, eddy-current loss can be held small. Further, the Young's modulus of the insulating spacers 2 is improved, thereby permitting the thickness reduction thereof.
