Title: Peep window
Inventor: ADACHI MASAYUKI
IPC: C03C27/12
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To provide an optimum peep window for an ion-exchange resin column or the like while it is such a peep window that a half-divided like granular filler does not stick thereto. SOLUTION: The peep hole is equipped with the same constitution as that of a traditional peep window excepting a constitution of a transparent plate 50. The transparent plate is made of an inorganic or organic glass plate, and a plate face 52 of the transparent plate 52 facing an inside of an ion-exchange resin column comprises a frosted glass-like irregular face. For the transparent plate, when a half divided ion-exchange resin sticks to the plate surface on a plane side, a clearance exists between the irregularity provided in the plate face and the half divided ion-exchange resin, a surface tension acting between the half divided ion-exchange resin and the plate face is consequently decreased, and the half divided ion-exchange resin becomes difficult to stick to the plate face.  The half divided ion-exchange resin sticking to the plate face is swepted away by water to be treated flowing down in an ion-exchange resin layer, and easily disconnected from the plate face. The plate face of the transparent plate is always maintained in an excellent seeing through state wherein the half divided ion-exchange resin does not stick.

IPC: H03K17/60
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a high voltage switch protection circuit that prevents a voltage applied to semiconductor elements from being excessive so as to protect a switch circuit because the semiconductor elements may be employed for a high voltage switch placed between a high voltage power supply and a load, a voltage is not uniformly distributed to the elements due to a stray capacitance or the like in a transient-state such as transition from on to off and the voltage exceeding the rated voltage of the elements and damaging the elements.

A base current adjustment TR Qc is connected to a base Gj of the TR Qj of each stage. The equalization resistance is divided to connect a voltage division point Kj to a base of a base current adjustment TR Qc, and when the collector-emitter voltage of the switch TR Qj rises, a very small current flows from the base current adjustment TR Qc to the base of the switch TR Qj to decrease the collector-emitter voltage.
