摘要:
A heat-developable photographic light-sensitive material is described, comprising a support having thereon, at least one layer containing a compound represented by the general formula (I) or (II) below: ##STR1## wherein R and R' each represents a group selected from a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aralkyl group, an aryl group, an amino group, an acylamino group, an alkoxy group, an alkylthio group, a sulfonylamino group, a heterocyclic ring group and a substituted group of them; X represents atoms forming a 5-membered or 6-membered ring; A represents a group causing a decarboxylation reaction.This heat-developable photographic light-sensitive material provides a high maximum density and low fog by heat-developing at a relatively low temperature and for a short time.

A fluid antioxidant for molten metal which comprises glass or ferrite in the form of tiny balloons having three or more sizes. The balloons are coated with powdered silicon and powdered spinel to make their surface softer and more abrasive.
摘要:
A static type circuit breaker in which a transistor is arranged in the current path by which electrical power is supplied to a load from a power source. If short circuit trouble occurs, the fault current flowing in the load circuit is detected so that a luminous diode in a detector circuit is made to cease emitting light. A phototransistor photocoupled to this luminous diode and arranged in the base circuit of the transistor is made non-conductive and produces a short circuit between the base and the emitter of the transistor, whereby the transistor is made non-conductive so that the fault current is cut off.
摘要:
An electromechanical driving device comprising a permanent magnet rotor mounted for rotation on a non-magnetic support plate, and a wheel train mounted on the support plate and driven by the rotor. A coreless field coil is mounted on the support plate and positioned to drive the rotor and thereby drive the wheel train when the coreless field coil is energized. The coreless coil is wound on a coil bobbin having an axial bore. The support plate includes a projecting portion dimensioned to fit within the axial bore of the bobbin to support the bobbin and thereby mount the same on the support plate.

摘要:
Provided is a dehydroabietic acid polymer including a skeleton of the following formula (A) as a repeating unit: wherein L represents a divalent organic group. Methods for producing the dehydroabietic acid polymer are also provided. The dehydroabietic acid polymer has high resistance against moisture and water and high impact resistance. The dehydroabietic acid polymer can also be produced from a rosin-derived natural product.
摘要:
Scattered radiation is estimated by using a reduced image generated from a projection image, and the scattered radiation image of the projection image is acquired by enlargement processing. The scattered radiation correction of the projection image is executed by subtracting the obtained scattered radiation image from the projection image. In addition, when a primary X-ray image and a scattered radiation image in each projection direction are to be obtained by sequential approximation calculation, a primary X-ray image which has already been identified in an adjacent projection direction is used as a first estimated value (initially set value) in next sequential calculation.
