Title: Opening/closing valve
Inventor: YOSHIYAMA SHIGERU
IPC: F02M37/00
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To suppress leakage of fluid from a sealed portion between a sealing member and a valve member to the valve opening side with a simple structure. SOLUTION: A spool 37 has a large diameter part 39, and a small diameter part 38 having an outer diameter smaller than that of the large diameter part 39 on its closing valve side. A seal member 41 doubly seals a spool 37 by means of a first lip 41a and a second lip 41b. The first lip 41a is slid on the small diameter part 38, while the second lip 41b is slid on the large diameter part 39. Angles between the lips and an outer peripheral wall of the spool 37 are set as follows: α1 >β1 , α2 >β2 . Namely, in the first lip 41a, fluid easily flows from a variable capacity chamber 60 to the closing valve side. In the second lip 41b, fluid easily flows from the opening valve side to the variable displacement chamber 60. It is thus possible to suppress the leakage of the fluid from the closing side of the seal member 41 to the opening side.

Abstract: PURPOSE:To contrive to change fine elements into high density and integration ones without contamination by a method wherein elements are isolated by one time photoetching, and an insulation film is buried flat into a field region by low temperature treatment. CONSTITUTION:After reactive ion etching is performed by applying a resist mask 13 on a thermal oxide film 12 of a P type Si substrate 11, resulting in the formation of a recess, an inversion prevention layer 14 is formed by ion implantation. A SiO2 15 is superposed by plasma CVD method and treated with buffer fluoric solution, and accordingly a V-groove 16 is formed in the periphery of the recess by the difference of etching speeds. A resist film 17 is coated, the surface flatted approximately is etched by reactive ion, etched at the same speed by selecting the conditions of heat-treating and etching the resist 17, and then the resist 17 is removed by exposing the projection film 15. When a CVD SiO2 18 is uniformly deposited, a resist 19 is superposed, and the substrate is exposed by likewise etching the flatted surface by reactive ion, the SiO2 15 and 16 is buried flat in the field part. In this constitution, contamination does not occur because of no use of Al or resist mask for forming the film 15, and accordingly the element characterististic is stabilized.

IPC: A45B25/02
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To effectively shelter a user from rain and wind while the field of vision is widened when an umbrella is used. SOLUTION: A bone 1 forming one diameter is formed of a member with a bending rigidity of such a dimension that gives no bending by the tension even when the umbrella is opened and a raw fabric 3 is stretched and the other bones 11 are formed of members with a bending rigidity of such a dimension that provides smaller bending rigidity that that of the bone 1 and generates bending at the connecting part with a receiving bone 2 when the raw fabric 3 is stretched. As the bone 1 is not bent downward by doing so, the end part 6 comes to a position being upper than the positions of the end parts 16 of the other bones 11 to result in widening the field of vision in the up and down direction by the difference S in the height.

Abstract: PURPOSE: To make it possible to access freely two-system RAMs by prolonging the period of a clock signal when a selected storage circuit does not agree with a storage circuit which a CPU accesses.  
     CONSTITUTION: When RAM switching signal f generated in 21 in clock signal generation circuit 4 is inputted, clock signal a is inputted to CPU1, and least significant address signal j is "1", and therefore, output signal k of three-input AND circuit 24 is not outputted by exclusive OR 23 between f and j. Next, when signal f disappears, k is outputted, and clock signal b is outputted instead of signal a, and first RAM15 is connected to CPU1, thereby enabling read/write. Thus, signal a is prolonged in case that a RAM connected to CPU1 is accessed when signal a is inputted, and signal b is outputted when the RAM to be accessed again and CPU1 are connected after that, so that data can be read or write from the CPU.
