Title: Formation of ti-al intermetallic compound member
Inventor: SHIBUE KAZUHISA
IPC: C22C1/04
Filed: 1985-09-24
Abstract: PURPOSE:To form the titled compound having excellent strength at high temp. and oxidation resistance easily into required shape by forming a Ti-Al intermetallic compound by application of powder metallurgy. CONSTITUTION:Powdered Al (18-50wt%) is mixed with powdered Ti (50-82wt%). Then the resulting mixture is placed in a hermetically sealed vessel to undergo deaeration treatment by means of a vacuum pump, etc., so that adsorbed gases and adsorbed water on the powder surface can be removed and simultaneously oxidation in the following stage can be prevented. After that, this deaerated mixture is heat-treated under high temp. and high pressure. In this way, Al is allowed to diffuse into Ti to form the Ti-Al intermetallic compound. At this time, numerous pores caused by the diffusion of Al develop into cavities, which are crushed by high pressure treatment, for instance, hot isostatic pressing (HIP) treatment.

Title: Manufacture of metallic vacuum double wall vessel
Inventor: WAKATSUKI TOMOHIRO
IPC: C21D9/00
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To make Cu precipitate on the surface of base material and to display required antibacterial property in a prescribed part by annealing at a specified temperature for a specified time on condition that a stainless steel sheet is kept in a state in which Cu does not make solid solution in the base material but precipitate in a prescribed state between deep drawing and after working. SOLUTION: A metallic vacuum double wall vessel A is composed of internal and external vessel 21, 22 made of stainless steel subjected to deep drawing, and above all the internal vessel 21 is formed of an antibacterial stainless steel in which Cu is precipitated in the base material. The above Cu precipitates and elutes on the surface of base material too, which causes the antibacterial action on bacteria attached to the outer surface. Before the deep drawing, the material subjected to intermediate drawing is annealed at 900 deg.C or so for around 3-15 min. Cu contained in the stainless steel itself forming the internal vessel 21 is ionized, and, through elution or precipitation, sterilizes and suppresses the increase of bacteria so prevention of food poisoning due to bacteria is attainable.

Title: Unwinding and winding core mounting device
Inventor: KATAOKA AKIRA
IPC: B65H18/06
Filed: 1986-09-10
Abstract: PURPOSE:To increase a force of friction of a device with a core and to reliably secure the core, by providing a one-split expansion contraction ring which is moved over the taper surface of the outer periphery of a shaft head, supporting a core in a pressure contact manner, and has a flange part having inner periphery matching the taper surface of the outer periphery. CONSTITUTION:When a core 11 is mounted from the lock end part 6 side of a shaft head 3, a flange part 9 is brought into contact with an end part 13 of the core 11. When the core is further pushed in, a one-split expansion contraction ring having a flange part 9 is slid. As a result of the core being moved to the large part side of a taper part 5, the one-split expansion contraction ring having a flange part is expanded through the medium of a split part. Since the core is positioned to the large part, the core 11 is firmly locked. Since a one-split ring 10 has the flange part 9, expansion and contraction is facilitated and therefore, grooves 12 are formed at a proper distance from a periphery in a state to contain the flange part 9. The thickness of a bottom 14 is decreased, and an expansion contraction force needed against press is easily and strongly exerted. The groove may be formed in a proper shape, e.g. a square shape, a round shape, and the width of the groove is decreased on the outer periphery side, and is gradually increased toward the inner periphery side.

Title: Original point resetting device for robot
Inventor: HARADA TADANORI
IPC: G05D3/12
Filed: 1989-08-21
Abstract: PURPOSE:To improve the positional precision of the device by securing a slow change of the output of a detecting part to the positional change of a masking member, that is, by avoiding a large change of the output of the detecting part to a minute moving extent of the masking member. CONSTITUTION:A masking member 21 includes the oblique side parts 24a and 24b at both edge parts of the member 21 in its moving direction and is provided with a comparison means 30 and an original point position calculation means 34. The means 30 compares the output level of an original point sensor 20 with a reference level. Then the means 34 calculates a section distance based on the output signal of a distance measurement means 10 at the time point when the comparison result signal received from the means 30 changes at the mesking start and end time points of an original sensor 20 consisting of both parts 24a and 24b of the member 21. Then the means 34 calculates an unchang ing point within said section despite the variance of the maximum output level of the sensor 20 and the reference level. In such a constitution, the position of an original point is free from the variance of the ambient temperatures or the reference level applied to the means 30. Then the positional precision is improved for an original point resetting device for robot.
