Title: Adjuster for velocity of flow at exhaust port of chimney and the like
Inventor: SHIMOYAMA YOSHIAKI
IPC: F23L17/02
Filed: 1982-05-04
Abstract: PURPOSE:To make constant the velocity of flow of exhaust gas irrespective of the size of an exhaust gas quantity, by installing rotatable moving baffles at a top part of a tube body such as chimneys. CONSTITUTION:When a boiler is operated on a full load, moving baffles 6, 7 and 8 are brought to a vertical attitude by means of a screw jack 10 to minimize a draft resistance. In the case of a low load operation, the moving baffles 6, 7 and 8 are inclined at a given angle through the working of the jack 10. The inclination of the moving baffles 6, 7 and 8 narrows an opening area of a chimney 1 to reduce the flow of exhaust gas. This method adjusts the inclining angles of the moving baffles 6, 7 and 8 according to an exhaust gas quantity, and reduces the flow of exhaust gas so that the velocity of flow of exhaust gas is normally kept constant.

Filed: 1995-03-31
Abstract: PURPOSE: To reduce the deformation of a bonding tool caused by a temperature difference which is generated as the bonding tool grow cold by putting heat isolating spacers for forming heat transmission inhibiting space between the bonding tool and vertical moving mechanism. CONSTITUTION: A plurality of heat insulating spacers 15 which are used for forming a space 16 having a uniform width over the total length and obtaining a heat insulating effect are provided between a bonding tool holding section 1b and vertical moving mechanism 8c.

Abstract: PURPOSE:To easily cope with the color change of a measurement subject by converting the signal obtained from the synchronous detection into a digital signal, applying this digital signal to a memory as an address signal, and extracting a specific color based on the memory contents for recognition of a shape. CONSTITUTION:A chrominance signal separator 3 separates an input signal CS and outputs a chrominance signal S1 and a luminance signal S2 to a synchro nous detection circuit 4 and an A/D converter 5 respectively.
