Title: Flow-rate pressure control valve
Inventor: UEHARA KAZUO
IPC: F15B11/05
Filed: 1984-02-10
Abstract: PURPOSE:To prevent the deterioration of the minute-amount control performance by allowing the primary side port and a spring chamber to communicate through a gap formed between a metering pin and a poppet. CONSTITUTION:When a poppet valve 2 is in closed state, the primary-side port 11 and the inside of a spring chamber 1b are allowed to communicate each other in the throttled state by the gap between the valve opening 2b and the large- diameter part 3c of a metering pin 3 gently fitted into the valve opening 2b in the poppet valve 2. When a pilot pressure Pi is introduced into a chamber 5d from a pilot port 52 in this state, a pilot poppet 9 is opened, and the pressure in the chamber 5h lowers, and the pressure P2 in the spring chamber 1b lowers. Therefore, a pressure difference is generated, and the pressurized oil flows into the secondary-side port 12 from the primary-side port 11.

IPC: H01M10/42
Filed: 1986-02-03
Abstract: PURPOSE:To prevent the performance of an alkaline storage battery from deteriorating due to the leak of an electrolytic solution or the like, by providing minute hollow organic balls having pores in the surfaces thereof and containing the electrolytic solution therein, to place the balls on an electrode assembly to constitute the battery. CONSTITUTION:Minute hollow balls 3 having pores in the surfaces thereof and made of a methyl methacrylate resin or the like are caused to contain a solution of potassium hydroxide or the like therein. An electrode assembly made by winding a positive electrode 4 of nickel or the like and a negative electrode 5 of cadmium or the like with an interposed separator 6 is caused to retain a minimum amount of an electrolytic solution and then housed in a case 7. The minute hollow balls 3 containing the solution of potassium hydroxide or the like are filled in the internal opening of the case 7. A nickel-cadmium battery or the like is thus constituted. The balls 3 are pushed due to the repetition of charge and discharge to release the electrolytic solution to supply it. The electrolytic solution is thus prevented from becoming insufficient, to stabilize the performance of the battery.

Filed: 1990-02-02
Abstract: PURPOSE:To intensify an adhesive force and to improve the damage resistance to a laser beam by uniformly heating a chalcogenide glass substrate or the end faces of a fiber at the time of forming the antireflection film. CONSTITUTION:The antireflection film is laminated on the chalcogenide glass substrate or both end faces of the same glass fiber. Although the reflection loss of the surface is decreased by the provision of the antireflection film, the strength of adhesiveness and the damage resistance to the laser beam is inferior. The substrate or the end faces of the fiber are, thereupon, uniformly heated. The strength of adhesiveness and the damage resistance to the laser beam are improved in this way. The uniform heating at the heating temp. at which the grain boundaries are most densely formed in the case of a crystalline film and are formed but in the hardest manner in the case of an amorphous film, i.e. the temp. below the minus 30 deg.C of the glass transition temp. (Tg) at the end faces of the fibers, is desirable.
