Title: Caster whose loading support goes straight on without moving right and left in reverse advance
Inventor: IE TOMOSUKE
IPC: B60B33/00
Filed: 1993-02-16
Abstract: PURPOSE:To dissolve moving of a caster loading support right and left taking place when a caster makes reverse advance and prevent abrasion & break of wheels by smooth advance. CONSTITUTION:A wheel shaft 4 with about 68 deg. deflection angle to a fulcrum pedestal and a fork 3 & a fulcrum bearing 2 which are eccentric to a rotary axis of the fork, are constituted in double excentricity, and the bearing rotates along the racing core of the pedestal. Therefore, the caster of the fork 3 rotates by itself within a range of about 0-30 deg. in travelling and shows caster-effect function, and concerning caster-effect over 30 deg., the pedestal 1 does not move due to movement of a wheel 5 itself by eccentric rate, because the fulcrum bearing 2 revolves along the racing core face of the pedestal 1. Consequently this caster has effect that the loading support goes straight on without moving right and left in its reverse movement.

Title: Method and apparatus for automatically controlling gain of radiation measuring apparatus
Inventor: OYAMA TATSUO
IPC: G01N9/24
Filed: 1991-03-29
Abstract: PURPOSE:To set an optimum dynamic range at high speed and highly accurately control gain by performing two times differentiation with respect to a characteristic curve of an energy to counting value corresponding to a pulse height diagram. CONSTITUTION:Radioactive rays which have passed from a radiation source through a sample to be measured are detected by a detector 10, and the number of detected signals is counted by a counter 13 per signal level corresponding to each energy of a plurality of stages. The signal level to counting value is subjected to two times of differentiation with respect to a characteristic curve of a counting value corresponding to a pulse height diagram, the signal level corresponding to the minimum is determined to correspond to decay energy of the radiation source, and gain of the detector 10 is automatically controlled so that difference from a statically determinate signal level of the decay energy is zero. The two times of differentiation allow peak energy corresponding to the decay energy of the radiation source to be detected highly accurately, the difference from the statically determinate signal can be directly obtained, the gain of the detector 10 can be optimally controlled, and time required to reach stabilization can be reduced.

Filed: 1983-04-19
Abstract: PURPOSE:To promote denitrification without obstructing melting work, in a vacuum induction melting furnace, by blowing gas into a molten metal by immersing a lance in said molten metal from the upper part thereof. CONSTITUTION:A base material is melted in a vacuum induction melting furnace 2 or a molten bath is supplied to said furnace 2 from a laddle and maintained at a predetermined temp. while a vacuum tank 1 is evacuated. A lance 3 is immersed in the molten metal in the melting furnace 2 from the upper part of the vacuum tank 1 to blow inert gas such as argon, CO-gas or a gaseous mixture thereof into said molten metal to promote the denitrification of the molten metal under stirring. By this method, the extremely low nitrificaion of the molten metal can be realized and adverse affect is not exerted on furnace refractory. In addition, because the immersion depth of the lance 3 and gas flowing can be arbitrarily set, stirring can be arbitrarily controlled.
