Title: Method for adjusting wall thickness of hollow molding
Inventor: TSUJIKURA TAKASHI
IPC: B29C49/04
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To prevent the local thinning of the wall of a hollow molding in blow molding. SOLUTION: After the extrusion of a parison 15, a cooling medium is sparyed from a cooling nozzle 16 to a part of the parison 15 corresponding to a place of a molding in which the wall is to be thinned locally. When the cooling medium is sprayed during the extrusion of the parison 15, the cooling nozzle 16 is moved according to the extrusion of the parison 15. Since a place the temperature of which is decreased by the cooling medium is resistant against expansion, the wall thickness of the place, where the wall is to be thinned, tends to increase so that the molding is uniform in wall thickness.

Title: Relief valve
Inventor: EJIRI TAKASHI
IPC: F16K47/02
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To be opened by a pressure except for a set pressure and to secure a stable relief characteristics by providing a pressure chamber applying a fluid pressure in the valve opening direction against an energizing means of a valve element and by providing an orifice in a pressure introduction port to the pressure chamber. SOLUTION: This relief valve has an inlet port 12 connected to a tank which is, for example, to be held at a prescribed pressure or less, and a valve element receiver 21 is seated on a valve seat 15 by a force of a compression spring 29 at all times so as to intercept the communication between the inlet port 12 and an outlet port 13. When a tank internal pressure exceeds a prescribed value, a pilot pressure is applied on a pressure chamber 30 via a fluid pressure introduction port 31. The pilot pressure moves a valve stem 20 in the valve opening direction against the force of the compression spring 29 so that the valve element receiver 21 is separated from the valve seat 15 and the tank internal pressure is relieved from the outlet port 13.  Then, an orifice 32 is provided in the fluid pressure introduction port 31 of the pressure chamber 30 so that the vibration phenomena of the valve stem 20 is prevented and accurate relief characteristics are provided, even if the tank internal pressure or the pilot pressure is fluctuated in a narrow range.

IPC: C23C4/12
Filed: 1991-10-16
Abstract: PURPOSE:To obtain a coating layer excellent in the degree of adhesion and also to reduce the surface oxidation of thermally sprayed grains by using the thermally sprayed grains prepared by allowing a metal body to collide against a metal plate at high speed and atomizing the metals of the metal body and the metal plate. CONSTITUTION:When a metal body is allowed to collide at high speed against a metal plate 2, temp. rise is brought about as the result of adiabatic compression due to the resulting shock wave and the metals of the metal body and the metal plate 2 are melted or evaporated, by which atomized high-speed thermally sprayed grains 8 are formed. These high-speed thermally sprayed grains 8 are sprayed on a body 3 to be sprayed to form a metal coating layer. The coating layer on the body 3 to be sprayed is composed of a single metal when the metal body and the metal are composed of a single metal, and, on the other hand, the alloyed coating layer can be obtained when they are composed of different kinds of metal respectively.

Title: Fluid bearing device
Inventor: YOSHITSUGU TAKAO
IPC: F16C33/10
Filed: 1988-10-25
Abstract: PURPOSE:To obtain the high speed and long life of the captioned device by holding a lubricant between a shaft end face and a thrust receiving member and fixing a ring which has a small gap coaxial with a shaft while being in contact with a sleeve and the thrust receiving member and which is impregnated with a lubricant. CONSTITUTION:As a rotary shaft 1 is rotated, a lubricant 8 is collected to the center of a shaft end face 1b by means of grooves 5a for generating dynamic pressure of a thrust board 5 to float up the shaft 1. The lubricating oil 8 in the vicinity of the surface of the shaft end face 1b tends to flow out along the outer periphery of shaft due to centrifugal force. At this time, the lubricant filled in a thrust ring 4 is drawn into a shaft center in the vicinity of the thrust board 5 while, on the contrary, the lubricant is drawn into the thrust ring 4 on the portion opposite to the shaft surface 1a, thereby, circulating the lubricant 8 through the inside of the thrust ring 4. Hence, the flow-out of the lubricant can be made minimum obtaining the high speed and long life of a device. It is also possible to use a similar structure in a radial bearing.

Title: Operating method for solid secondary battery
Inventor: MATSUMOTO HITOSHI
IPC: H01M4/58
Filed: 1988-10-25
Abstract: PURPOSE:To provide a solid secondary battery with long life, which presents two stages of discharging voltage, by using a one with low discharge voltage. CONSTITUTION:When Cu chevrel phase compound is selected both to a pos. and a neg. electrode while Cu ion conductor to an electrolyte, in particular, RbCu4IxCly series solid electrolyte, two flat parts are obtained at the time of discharging, i.e., at 0.5-0.3V as first stage and 0.2-0.05V as the second stage. Therein control shall take place so that the lower voltage is used. That is, a value ranging 0.2-0.4V is adopted as the set voltage at the time of constant voltage charging, while the upper limit is set to 0.4V at the time of constant current charging. This prevents the pos. electrode from having a high potential, precludes the capacity from dropping at a comparatively small cyclic number, and prolongs the lifetime.
