Title: Transition piece of gas turbine combustor
Inventor: ITO MASAO
IPC: F23R3/42
Filed: 1993-05-11
Abstract: PURPOSE:To eliminate the need of sealing parts between an outer cylinder and a picture frame by supporting the downstream side of an inner cylinder with a support fitment fixedly mounted on a turbine casing, and positioning and fixing the downstream side of the outer cylinder at and to the most downstream portion of the inner cyllinder directly through a coupling mechanism. CONSTITUTION:The downstream side of an outer cylinder 2a of a transition piece 1 is fixedly mounted integrally or substantially integrally on an inner cylinder 2b through a coupling mechanism 22 before a picture frame 17. For this, the outer cylinder 2a is thermally elongated only in an upstream direction from, as a start point, a bolt being fixing means of the coupling mechanism 22, and hence there is eliminated the need of sealing parts between the outer cylinder 2a and the picture fame 17. Further, the axial clearance between the outer cylinder 2a and the picture frame 17 is reduced as much as possible. In contrast, for the fixing of the outer cylinder 2a and the inner cylinder 2b on the upstream side of the transition piece 1, thermal elongation thereof in the upstream direction is moderated by a sliding portion because a ring 20 and the outer cylinder 2a are slidable axially.

Abstract: PROBLEM TO BE SOLVED: To make a container holdable by hand immediately after it is filled with high temperature food and drink or the container itself is heated by a method wherein a plurality of indentations and protuberances are formed at the side circumferential wall of the container. SOLUTION: A container 1 is such that is producible out of materials which are not specially limitted. The container is used for such purposes as heating food and drink together with the container, containing high temperature food immediately after heated or containing food for which a boiling water is inpoured. For this high temperature food and drink container 1, a plurality of horizontal ribs 2 and vertical ribs 3 are formed at the circumferential wall 1d of its lateral. Thereby, the area at the circumferential wall 1d at the lateral contacting with hand when the container 1 is held by hand becomes small.

Title: Variation relay
Inventor: MACHIDA SATOSHI
IPC: H02H3/50
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent an erroneous detection of a variation of a quantity of electricity in the case that an input waveform of a relay becomes an overlaid waveform of distorted waves which has a fundamental wave of a constant cycle beat waveform due to the existence of a flicker load in the system by comparing a variation of a quantity of electricity, such as current between of the present value and the value the specified number of cycles before of the fundamental wave, with a set value. SOLUTION: A digital variation current relay calculates a variation of current from a difference between the present input value and the input value 'a' cycles before, where 'a' is a value corresponding to a specified time period. In the case that a flicker load exists in the system, load current has a beat waveform made by overlaying n±10 [Hz] components on a fundamental wave frequency n [Hz] (n=10×m, where 'm' is an integer). The value corresponding to a specified time period 'a' where the periodicity of the waveform of a frequency 'n' [Hz] and that of a frequency n±10 [Hz] are the same 'm'. Therefore, by calculating a variation in the current from a difference between the present input value and the input value 'm' cycles prior to the fundamental wave, a misdetection of the variation when the flicker load exists in the system can be prevented.
