Title: Air-conditioned seat
Inventor: IMAMURA TOSHIHIDE
IPC: B60H1/34
Filed: 1990-02-27
Abstract: PURPOSE:To produce comfortable air conditioning action by oscillatably and pivotally mounting a piston with an air suction hole at an end of a plate to hold a seat having many air jetting holes to jet air from the seat as the piston oscillates. CONSTITUTION:When a motor 13 with a reduction gear is driven, a piston 7 moves vertically through a crankshaft 12 and a link 11 taking a connecting part between the piston 7 and a plate 3 as a supporting point. When the piston 7 oscillates downward, a suction preventing valve 6 attached to the plate 3 closes, and on the other hand, a suction valve 10 attached to the piston 7 opens to draw air into a space between the plate 3 and the piston 7. When the piston 7 oscillates upward, the suction valve 10 closes, and on the other hand, the suction preventing valve 6 opens to push out the air through an air hole 4. Thus the air is blown against a driver's body from the air jetting holes 2 of the seat 1 to produce comfortable air conditioning action.

Title: Lens barrel
Inventor: OONUKI MITSUO
IPC: G02B7/04
Filed: 1981-04-01
Abstract: PURPOSE: To reduce the production cost of lens barrels, by eliminating the fitting between metals through their diameters for the lens barrel.  
     CONSTITUTION: A guide slit 2 extending toward the optical axis is provided to a guide frame 1 corresponding to a fixed barrel, etc. at two areas with 90° angle distance, and a sliding bar 4 made of a resin material is attached at two areas of a mobile frame 3 which functions as a lens holding frame. These two bars 4 engage with each other with their side faces attached close to the side face of the slit 2 respectively. As a result, the frame 3 has a free movement only toward the optical axis as long as the two slits 2 have the angular relation excepting 180°. Thus the frame 3 can have a displacement toward the optical axis without any fitting between the frames 2 and 3. Then the frame 3 has a displacement toward the optical axis by the engagement between a mobile pin 6 of the bar 4 and a driving member 7. In such way, the fitting between metals through the diameter can be eliminated to reduce the production cost of a lens barrel.

Title: Method of heating semiconductor and susceptor used therein
Inventor: SAKAI TAKAMASA
IPC: H01L21/22
Filed: 1986-03-06
Abstract: PURPOSE:To improve the energy conversion efficiency, by applying alternate magnetic fields to a low-resistance ferromagnetic body isolated from the treating atmosphere of a heat treating apparatus by means of an material inactive to the treating atmosphere so as to cause the low-resistance ferromagnetic body to generate heat for heating a semiconductor. CONSTITUTION:In a quartz tube 1 isolating the treating atmosphere from the outside air, a susceptor 2 is provided for carrying a semiconductor wafer 3 thereon. The susceptor 2 is composed of a planar, low-resistance and ferromagnetic body 2a the surface of which is covered with an inactive material 2b which is inactive to the treating atmosphere. Since the low-resistance ferromagnetic body 2a of the susceptor 2 is interposed in the magnetic path of a coil 4, magnetic flux produced in the coil 4 is allowed to pass through the susceptor 2 at a high efficiency and produces eddy current in the low-resistance ferromagnetic body 2a of the susceptor 2, whereby the susceptor 2 is heated. In this manner, a large quantity of heat can be generated without increasing current supplied to the coil or a frequency thereof and the conversion efficiency of the power consumption to the quantity of heat is improved.
