Title: Wind velocity measuring instrument
Inventor: AKITA SHUZO
IPC: G01P5/18
Filed: 1985-01-28
Abstract: PURPOSE:To detect the wind velocity accurately by providing a heater means in an air current and providing a temperature detecting means at its downstream and measuring the wind velocity by measuring the time difference until a temperature rise of the air current is detected. CONSTITUTION:When a heater 14 is made on, the heater 14 generates heat from that point of time and the generation of the heat is diffused in the air current and the temperature rise of the air current is detected by a temperature detector 16 provided at its downstream. The time until the temperature rise is detected after the heater 14 is made on is measured, for instance, by a timer 24. A distance between the heater 14 and the temperature detector 16 is fixed. Consequently, if the arithmetic dividing the distance by the time difference is performed through an arithmetic circuit 28, the wind velocity or the flow velocity at that time can be measured accurately.

Title: Production of seamless extend-forged steel pipe having excellent carburization resistance
Inventor: YANO YOSHINORI
IPC: C21D8/10
Filed: 1988-01-25
Abstract: PURPOSE:To stably produce a seamless extend-forged steel pipe having excellent carburization resistance and having no problems in high-temp. strength, etc., by molding a high-Cr-high-Ni heat resisting steel to the seamless extend-forged steel pipe, then subjecting the steel pipe to the final heat treatment in a nonoxidative atmosphere. CONSTITUTION:The 25Cr-32Ni heat resisting steel is used as a stock and is molded to the seamless extend-forged steel pipe by a conventional method. This steel pipe is subjected to the final heat treatment intended for a soln. heat treatment in the nonoxidative atmosphere. A simple gaseous substance of a neutral or reducing gas such as H2, Ar or N2 or a gaseous mixture composed thereof is used as the nonoxidative atmosphere. The adequate heat treatment temp. is about 1200-1250 deg.C. Formation of oxide scale is thereby suppressed and the transfer of Cr to an oxide scale layer is prevented so that the concn. of the Cr in the surface layer and the concn. of the Cr in the base material part are maintained at substantially the same concn. This steel pipe forms the oxide scale layer consisting of a Cr oxide having a dense crystal structure at the time of use to substantially prevent atom diffusion. The steel pipe having the excellent carburization resistance is thus obtd.

IPC: G01T1/208
Filed: 1995-02-02
Abstract: PURPOSE: To provide a filter amplifier, for a scintillation detector, which can satisfy both a counting rate characteristic and an S/N ratio. CONSTITUTION: A light-emitting signal from a scintillator 20 is converted into a voltage by an I/N converter 21 so as to be inputted, through a delay circuit 22 and an amplifier 23, to a baseline regeneration circuit which comprises an inverting amplifier 24, an integrating circuit 25 and a buffer 26. The time constant of the integrating circuit 25 is set to be equal to the attenuation time constant of the scintillator 20.

As the carbon black, any of electric-conductive carbon blacks and other ordinary carbon blacks can be used in a single form, or two or more sorts of these materials can be used in a mixed form. The loading ratio of the resin and the carbon black is suitably 20-200 pts.wt. of the carbon black to 100 pts.wt. of the resin. A resistant layer is obtained by a method wherein the carbon black and the resin are uniformly mixed and, thereafter, formed to be a film- form layer of 30mum or less thick by a melt extrusion method etc.
