Abstract: Provided is an embroidery frame clip which can effectively prevent itself, without marring operability of fitting it to an embroidery frame, from slipping off the frame, when the tension of an embroidering cloth is increased as stitching goes on. The embroidery frame clip is designed to hold an embroidering cloth a in tension over a rectangular embroidery frame 1 by clipping the cloth a between a rail 2 formed on an upper surface of the embroidery frame circumferentially along the inner rim thereof and the clip fitted on the rail 2. The clip has a clip main body 6 to be fitted on the rail 2 and auxiliary members 7 attached to the clip main body 6, for preventing the clip main body 6 from deforming to open as stitching of the embroidering cloth goes on.

Abstract: A heat transfer apparatus with a zigzag passage is provided. The apparatus includes a pair of opposed plates 11, 12, a bent plate 21 having a wavy cross sectional shape for dividing the space between both plates into a plurality of side-by-side passages 20a, 20b, and a pair of cover members 13, 14, bonded to the bent plate 21, for forming connecting portions 20c, 20d between the side-by-side passages. One sidewall portion 23a of both sidewall portions 23a, 23b of the bent plate 21 is coupled to the cover member 13 on one end of a rectangular groove. The other sidewall portion 23b is coupled to the cover member 14 on the other end of the rectangular groove. Thus, a zigzag passage 20 is formed in which one side of the rectangular groove is folded to oppose the other side of the rectangular groove.

Abstract: Disclosed is a paint drying furnace for baking and drying paint films on painted objects following a painting process. The furnace of the invention has an interior combustion type heating device arranged on fresh air passages upstream of points of connection to furnace interior circulating gas passages for heating passing fresh air. The combustion type heating device is a direct heating type, combustion type heating device for burning a fuel directly in an atmosphere of passing fresh air to be heated.

Abstract: Disclosed is a paint drying furnace for baking and drying paint films on painted objects following a painting process. In the furnace of the invention, a shunt gas passage is provided for dividing a gas outputted from inner gas passages of a radiator means from a position of a radiator circulating gas passage upstream of a connecting point of a fresh air passage and mixing this divided gas into the gas circulating through the furnace interior circulating gas passage. With provision of this shunt gas passage, a combustion type radiator heating device acts also as furnace interior heating means.

Abstract: In a microprocessor including a data memory device a simple checking circuit is provided for reading out the data onto a data bus line to check whether the data must be debugged. The checking circuit reads out data stored in an accumulator, register, etc. onto the data bus line. The checking circuit allows the microprocessor to operate normally in the absence of a checking signal and respectively connects the accumulator, register, or RAM outputs to the data bus in accordance with the timing signals from the microprocessor timing signal generator in the presence of the checking signal. A program counter of the microprocessor is also inhibited from incrementing when the checking signal is present.
