Title: Upwardly directed sleeve valve with float
Inventor: HONDA TATSU
IPC: E02B9/00
Filed: 1983-01-11
Abstract: PURPOSE:To smoothly and quietly operate an upwardly directed sleeve valve with a float by a method in which a sleeve valve where the water pressure does not act on the opening and closing direction of the valve is provided to a pressure water inlet tube, and the stream of water in the pressure water inlet tube is smoothly directed toward the radial direction by means of a valve seat with a curved conical face. CONSTITUTION:A float 19 goes up and down on a valve body 14 according to the level of water in a water tank 1 and passes through the aperture between the upper end of the valve body 14 and the conical face 13a of a conic valve seat 13 to regulate the amount of water flowing from a pressure water inlet tube 2 into the water tank 1. Water coming out of the sleeve valve 21 composed of the valve body 14 and the conic valve seat 13 is directed from the horizon to downward direction by the fixed annular face 13b and the guide face 13c, where the water stream in the radial direction acts on the whole periphery of the valve body 14 uniformly but no water pressure is applied to the float 9. The flow of effluent water is smooth, the valve body 14 is therefore not vibrated, and a small shape of the float 19 is sufficient. The water tank 1 can thus be miniaturized.

Title: Circuit capable of varying number of protective stages
Inventor: ISHIZUKA MASAHIRO
IPC: H04L7/08
Filed: 1990-01-09
Abstract: PURPOSE:To set the number of protection stages variable and optionally by resetting the initial value of 1st and 2nd counters which count the same counting input when the counted values of both the counters are discordant with each other. CONSTITUTION:The 1st counter 71 is placed in the enabled state when a counting event object is generated, and the 1st and 2nd counters 71 and 72 begin to count up with the specific initial value, so that the number of times of the generation of events can be known from the counted value of the counter 71. When the generation of events is discontinuous, the counter 71 enters the enabled state and disabled state repeatedly and a difference in counted value between the counters 71 and 72 is generated in the disabled state. This difference is detected by an initial value setting circuit 73 and the initial value of the counters 71 and 72 is reset to repeat the counting of the number of times of continuous event generation. Consequently, the number of protective stages (number of times of generation) is variably set.

Abstract: PURPOSE:To obviate the necessity of heating exclusively for use in a heat treatment stage, to secure product shape after heat treatment, and to uniformize quality and structure by applying heat treatment to core materials in a state surrounded by covering materials by utilizing a heat retained by the materials after pack rolling. CONSTITUTION:For example, austenitic stainless steel SUS304 is used as core material, and covering materials composed of carbon steel SS41 are laid on respective upper and lower sides of four sheets of the core material and spacer materials composed of the same quality are disposed between the covering materials so that they enclose the core materials, and then, the covering materials and the core materials are welded together. The resulting laminated body assembled as mentioned above is heated up to 1000-1250 deg.C to undergo pack rolling, and the temp. after rolling is regulated to 850-1100 deg.C. Since this temp. is a heat treating temp. sufficient to prevent the precipitation of carbide by means of subsequent quenching, this retained heat is utilized, and the above laminated body is quenched down to <=200 deg.C and allowed to stand to be cooled down to ordinary temp., and then, the core materials are taken out from the covering materials.
