Filed: 1987-10-31
Abstract: PURPOSE:To fully pour foaming synthetic resin stock liquid in complicated shape, thin part and the like and consequently obtain a foam integral with a skin material excellent in economical efficiency and at the same time in cushioning property by a method wherein the desired blowing pressure is obtained by opening and closing a pressure valve which is provided on a foaming mold. CONSTITUTION:A skin material 22 is arranged in a bottom force 12 and the terminal 22a of the skin material 22 is held at a holding part 17 so as to pour foaming synthetic resin stock liquid 23' in the inside of the skin material 22. The first state after pouring consists of the closed state of a pressure valve 18, which lasts until the blowing pressure in a foaming mold 11 reaches the predetermined blowing pressure, the opened state of the pressure valve 19 at the predetermined blowing pressure for exhausting the blowing gas and remaining air in the foaming mold 11. After the predetermined period of time, the blowing pressure becomes constant and further after the predetermined period of time a foam 23 is obtained. The foam 21 integral with the skin material, which is foam-molded under said first state, has favorable molded state obtained with neither starved area in thin part nor impregnated part in the skin material 22.

Title: Method and device for obstacle evasion control over robot
Inventor: ARAKAWA AKIO
IPC: B25J9/16
Filed: 1989-10-26
Abstract: PURPOSE:To enable the robot to easily perform operation for obstacle evasion by adjusting the quantity of displacement for attitude matching and the quantity of displacement for obstacle evasion while judging the current attitude of the robot and whether or not the distance to the obstacle is long or short by a fuzzy rule. CONSTITUTION:The articulated robot 1 is equipped with a 1st arm 3 which is connected to a 1st joint 2 and a 2nd joint 5 which connects the 1st arm 3 and a 2nd arm 4 and the 1st joint 2 and 2nd joint 5 are both rotatable in a plane 6, so the articulated robot 1 has two degrees of freedom. The robot finds the distance to the obstacle by itself and employes the fuzzy rule based upon this distance as a condition, so the robot has a proper displacement quantity autonomously by combining attitude matching operation to a target attitude with obstacle evading operation and takes an attitude matching the target attitude eventually. Consequently, the robot can evade obstacles impeding its movement in order when put in the attitude matching operation.

Title: Structure of wick for heat pipe
Inventor: YAMAMOTO ITARU
IPC: F28D15/02
Filed: 1987-11-02
Abstract: PURPOSE:To improve heat transport capacity, by a method wherein a space part, formed between the inner wall surface of a closed pipe and a wick and a slit part communicating with a steam passage are formed in a wick approximately throughout an overall length in an axial direction. CONSTITUTION:In a space part 14 of a vaporizing part, working fluid is heated to produce air bubbles, and the air bubbles flow pass through the meshes and a slit part 13 of a wick 12 escape into a steam passage 15 while a grain size is small. The air bubbles staying in the wick 12 are united with each other for growth, but the air bubble flowing to the slit part 13 escape into the steam passage 15 after flowing through the slit because the opening area of the slit part 13 is wide. In any way, since air bubbles generated occasioned by heating of working fluid are discharged to the steam passage 15, the inner wall surface of a closed pipe 10 is prevented from being covered with the air bubbles, and thus, excellent heat transfer between the working fluid and the closed pipe 10 is performed.

Title: Film pack holder
Inventor: SATO TOKUJI
IPC: G03B17/52
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To prevent the cap of a film pack, from coming out with a simple structure by providing an energizing member for energizing the cap toward an engaging position with a slide at the time of opening a cover in the holder main body of a film pack holder. SOLUTION: When the projected line part 27 of the cover 21 is retreated from the groove part 2c of the cap 2 by the opening of the cover 21, the cap 2 is pushed by a pin 40 to be moved to the engaging position with the slide 5. When the pressing of a projection by the projected part of the cover 21 is released, a catch member 7 is raised by the energization of a spring part 7c and an engaging pawl 7a is engaged with restraining holes 5b and 5c. Therefore, even if the engaging position of the cap 2 with the slide 5 is deviated, the cap 2 is moved to the engaging position by the energizing force of a spring 46, to be engaged with the slide 5, so that the cap 2 can be surely prevented from coming out. The extent of the extrusion of the cap 2 by the pin 40 is set >=0.5mm. Thus, even if each member is shrunken when temp. is very low, the cap 2 can be surely prevented from coming out.

Title: Clamp circuit
Inventor: SAKASHITA HIROHIKO
IPC: H04N5/18
Filed: 1985-12-11
Abstract: PURPOSE:To stabilize clamping at signal switching by connecting a collector of the 1st transistor (TR), an emitter of the 2nd TR and a cathode of a diode to an output terminal of a capacitor. CONSTITUTION:In inputting a video signal, while a clamp pulse is at a high potential, the 1st TR 2 and the 2nd TR 3 are conducted, a video signal is clamped in a reference potential, and when the clamp pulse is at a low potential, the TRs 2, 3 are cut off and the output terminal of a capacitor 1 keeps the potential. When no video signal is inputted, it is possible for the clamp pulse to clamp a location other than a back porch, but the minimum point of the video signal is clamped by a diode 4. Thus, the diode is used at signal changeover and the minimum point of the video signal is clamped with the reference potential thereby stabilizing the clamping at signal changeover.

Title: Oil lubrication radial bearing device
Inventor: KOSHIRO KAZUTAKA
IPC: F16C33/20
Filed: 1992-10-16
Abstract: PURPOSE:To improve a bearing characteristic, long-term reliability and safety by providing on the inner periphery surface of a bearing to support a rotary shaft a cylindrical fluoric resin material provided with plural penetration holes in the axial direction of a circumferential groove, providing in addition a stop ring at a bearing end portion. CONSTITUTION:When a rotary shaft 1 is in stop state, a lubricant 4 is supplied, then it flows through an outer periphery groove 10b and is guided into an inner periphery groove 10a through a penetration hole 13. Thus, the lubricant is supplied to the slide surfaces of a rotary side bearing opening 7a and a bearing side bearing opening 7b. Meanwhile, when the rotary shaft 1 starts to rotate, the slide surfaces of the rotary side bearing opening 7a and the bearing side bearing opening 7b fall into a boundary lubrication (the middle of fluid lubrication and solid lubrication) state. At this time, by the elastic deformation of a fluoric resin material 9, the slide surfaces of the rotary side bearing opening 7a and the bearing side bearing opening 7b fall rather into a state near to fluid lubrication out of the boundary lubrication. That is, the state of elastic fluid lubrication is brought on.
