Title: Thermopile
Inventor: NEMOTO MICHIO
IPC: G01J5/12
Filed: 1989-10-12
Abstract: PURPOSE:To improve the efficiency of a temperature rise in the warm contact portion of a thermocouple pattern with respect to an incident infrared ray power by forming an elastic resin coating layer coated with the thermocouple pattern thereon an insulating substrate. CONSTITUTION:An elastic resin (usually polyimide resin is used) coating layer 3 is formed on the surface of an insulating substrate 1 on which a thermocouple pattern 2 is formed. The thickness of the elastic resin coating layer 3 is smaller than that of the substrate 1 and usually set to 5mum or less. The coating layer 3 has a heat conductivity of the same order as that of the substrate 1. The layer 3 is formed by a spin coating method. The surface of the pattern 2 is processed to be insulated by the layer 3. Thus, the infrared ray absorbing layer 4 of gold black can be formed on a circular region with a radius larger than that of a circle on which a warm contact 20 is arranged approximately by a clearance (k). Thus, heat is applied to the warm contact 20 from the peripheral portion of the absorbing layer 4 directly via the layer 3. This improves the efficiency of a temperature rise in the pattern 2 coupled with the fact that the thickness of the layer 3 is small.

Title: Forward/backward movement operator for traveling machine body
Inventor: ISHIDA YOJI
IPC: F16H61/36
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To easily and quickly carry out a switching operation by less force by arranging both of forward and backward movement side operation pieces separately operated by the operation of an operation lever in the operation lever switching the forward/ backward movement switching member and interlocking both operation pieces with the forward/backward movement switching member independently. SOLUTION: When an operation lever 3 is tilted down to the front side F, an operation roller 31 presses an operation piece 51 downward around a supporting shaft 50, so that a left-side wire 7 is pulled. Consequently, a forward/backward movement switching member is switched to the front side, and a traveling machine body is moved forward. On the other hand, when an operation lever 3 is tilted down to the rear side R, the operation roller 31 pushes up another operation piece 52, so that a right-side wire 7 is pulled. Consequently, the forward/backward movement switching member is switched to the rear side, and the traveling machine body is moved backward.  In this process, the operation lever 3 is operated against neutral returning springs arranged on the left and right sides of the forward/backward movement switching member, so that this operation can be easily and quickly carried out by less force.

IPC: H01L21/3065
Filed: 1987-10-21
Abstract: PURPOSE:To prevent an electrolytic corrosion and to prevent the operability of a dry processing device from decreasing due to the impossibility of use as a sample stand by forming the stand in a structure in which materials having potential differences are laminated, and forming a thermal medium liquid passage of the same material. CONSTITUTION:A sample base 10 on which a sample to be processed by a dry process is mounted is formed in a structure in which materials having potential differences are laminated, and a thermal medium passage 16 is formed of the same material. For example, the protrusion of a stainless steel of a sample mounting unit 11 can be engaged with each other with a stainless steel for forming a mounting unit 12, a recess deeper than the thickness of the protrusion is formed, and a thermal medium liquid supply passage 13 and a thermal medium liquid discharge passage 14 are respectively formed. In this case, the stand is formed in a structure in which aluminum and stainless steel having potential differences are laminated. Since the thermal medium passage is formed in the stainless steel section, the potential difference of the thermal medium passage is eliminated to prevent an electrolytic corrosion. Thus, it can prevent cooling water from leaking from the stand, and it can prevent the operability of a device due to the impossibility of the use of the stand.

Abstract: PURPOSE:To shorten the operation time of a thermal head and to increase the operation speed of a thermal head by providing a plurality of operation distances allowing the thermal head to be spaced apart from a platen. CONSTITUTION:A head pressing cam 9 has three stop points A, B, C. In a state before the starting of printing, the head pressing cam 9 is stopped at the position where the A-point comes into contact with the projection of a lever 10 and a thermal head 1 is set so as to hold a distance sufficient to easily perform the mounting and detachment of a ribbon cassette between a platen and the thermal head. In a printing state, the head pressing cam 9 is stopped at the position where the B-point comes into contact with the projection of the lever 10 to press the platen 13 through a transfer ribbon 15 and printing paper 16. When the printing of a line is completed, the thermal head 1 is allowed to be spaced apart from the platen 13 by the absolute min. distance. Therefore, the head pressing cam 9 is stopped at the position where the C-point comes into contact with the projection of the lever 10 and the thermal head 1 is slightly separated from the platen 13 to perform line feed.

CONSTITUTION: A solvent and a dye of red or blue, for example, are circulated through a filter, e.g. a filter paper or a screen of 325 mesh, using methylene chloride as an extraction liquid thus removing foreign matters and impurities. Crystal particles of that purified dye is then dried to obtain a dye from which methylene chloride is removed and the dye is mixed with an acryl based plasticizer. The mixture is fed through a triple roll thus dispersing the particles while pulverizing. It is filtered through a 200 mesh screen and a polycarbonate board 2 is injection molded using a coloring matter having maximum particle size of 50μm or less. Finally, irregular pits 2a and a reflective layer 3 are formed on the board 2 and covered with a protective layer 4 of UV-curing resin.  Consequently, an optical information recording medium having good optical characteristics can be obtained and the type, use, etc., thereof can be determined instantaneously by coloring.

Abstract: PROBLEM TO BE SOLVED: To make a whole lens system small in size, to excellently maintain a telecentric condition over a whole variable power range and to provide the excellent optical performance over a whole screen by properly using a diffraction optical element in a lens group. SOLUTION: A zoom lens PL is provided with a first group L1 of a negative refractive power and a second group L2 of a positive refractive power and at least one lens group between the respective lens groups L1, L2 has at least one diffraction optical element being rotary symmetric to the optical axis. At the time of varying the power from the wide-angle end to the telescopic end, the first group L1 and the second group L2 are moved to the side of a first conjugate point (the side of a screen S).

Title: Head device
Inventor: TAKASHIMA HIDEO
IPC: G11B5/55
Filed: 1984-12-18
Abstract: PURPOSE:To prevent the break of wiring at a head connection terminal by making the external diameter of the through hole of a rotary holder smaller than the external diameter of an elastic tube through which an external conductor is run, and fixing the conductor to the holder at a press-in part by pressing in the tube. CONSTITUTION:The external conductor 6 which connects the connection terminal 4 of a magnetic head 1 to an external circuit is run through a heat-shrinkable tube 7 having elastic force, and the tip side is contracted thermally and inserted into the through hole 5c of the rotary holder 5. In this state, the external diameter K3 of the tip of the tube 7 is set between external diameters K1 and K2 of the holder 5. Therefore, the tube 7 is caught in the through hole when inserted, but the tip part is led out and then the tube 7 deforms and is pressed in the through hole 5c, so that the conductor 6 is fixed to the holder 5. Consequently, even when the head 1 rotates according to a tape traveling direction, the part above the fixation part of the conductor 6 moves together with the holder 5 in one body, so the break of wiring at the terminal 4 is prevented.
