Title: Rod for drilling machine
Inventor: EBARA YOSHIO
IPC: E21B19/24
Filed: 1994-06-21
Abstract: PURPOSE:To improve the durability by greatly reducing the shock transmitted to a guide pipe from a rod through softening and preventing the breakage of the guide pipe and the abrasion breakage of an installation screw of a bit, as for the rod for drilling machine which is constituted so that the bit is installed at the top end and the guide pipe is mounted behind the bit. CONSTITUTION:A collar 10 which is constituted of an elastic body 11 inside and a metal ring 12 outside is fitted at the position where a guide pipe is applied with a thrust and held forwardly. When a feed is applied by a drilling machine, a thrust is transmitted on the guide pipe from a rod 6 through a collar 10. Though, in drilling, also the shock due to the percussion of the drilling machine is transmitted, besides the thrust force, at the rear end of the guide pipe from the collar 10, this shock is softened by the elastic body 11 of the collar 10 and greatly reduced.

Title: Transfer device for light pickup
Inventor: KANOUDA TOKIO
IPC: G11B7/085
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To hold the engaging state of an engaging part to the thread groove of a feed screw to secure a proper feed operation by forming the feed screw of a feed mechanism feeding a pickup in the prescribed direction into a multiple- start thread. SOLUTION: A feed screw 17 is formed is a double-start thread having two thread grooves 17a, 17b, and the thread grooves 17a, 17b are formed in a part excepting both ends. One end of the feed screw 17 is inserted into a bracket to fix it to a gear, and the other end of the same is set in the state that it is brought into elastic contact in the axial direction by a preload spring. Since an interval L between the two thread grooves 17a, 17b becomes a half of a pitch, the part between the thread grooves 17a, 17b in the feed screw 17 i.e., a flat part 17c becomes extremely small. Therefore, even if an engaging part 14a comes off the thread groove 17a or the thread groove 17b, the engaging part 14a is not left in the state that it runs up onto the flat part 17c, but the engaging part 14a is immediately screwed on the thread groove 17a or the thread groove 17b.

Title: Supercharged pressure control device in internal-combustion engine
Inventor: NOMURA KENICHI
IPC: F02B33/44
Filed: 1984-07-06
Abstract: PURPOSE:To prevent shocks upon supercharging, and to carry out a safe drive of an automobile, by providing a diaphragm type control valve which is opened by vacuum, in the intermediate part of a bypass passage so that vacuum is directly transmitted to a diaphram chamber or transmitted by way of a negative pressure delay mechanism. CONSTITUTION:Upon acceleration a throttle valve 4 opens greatly, and therefore, the vacuum at a port 13 becomes lower. This lower vacuum is transmitted to a diaphragm chamber 18. Since the vacuum is low, a valve element 22 is closed by the force of a spring 19. Upon turning, a steering wheel angle sensor 26 is turned on, and a VSV 23 is energized. The vacuum of a vacuum delay valve 15 becomes at once lower, but a higher vacuum in the diaphragm chamber 18 is held by a check valve 17 until it gradually becomes zero. The valve element 22 gradually descends under the tension of the spring 19.

Title: Vapor deposition device
Inventor: OSHIMA KIYOTAKA
IPC: C23C14/24
Filed: 1986-06-17
Abstract: PURPOSE:To quickly form vapor deposited layers having good and uniform thickness on both faces of a substrate simultaneously and to prevent the curling of the substrate by disposing the substrate perpendicularly at approximately the center of a pair of vapor flow guiding members disposed to face each other. CONSTITUTION:Vapor flow 2 of the evaporating metal generated by a vapor source 1 is branched by an antisticking plate 10 and is directed toward the respective vapor flow guiding members 4. The vapor flow 2 does not stick to the members 4 which are held at the temp. above the m.p. of the evaporating metal by a heater 3. The vapor flow evaporates again even if said flow sticks to said members and in the end the vapor flow is reflected by the members 4 so as to flow in the direction orthogonal with the plane of the figure until the vapor flow arrives at both faces of the substrate 5 disposed in approximately the perpendicular direction. The vapor flow 2 sticks successively to the surfaces of the substrate 5 kept heated to an adequate temp. by IR lamps 8 by which he metallic layers are simultaneously formed on both faces of the substrate 5. The above-mentioned members 4 are preferably formed of vapor flow reflection plates.
