Title: Production of nonwoven fabric
Inventor: TEJIMA TSUTOMU
IPC: D04H1/736
Filed: 1990-03-19
Abstract: PURPOSE:To obtain a nonwoven fabric having arbitrarily adjustable product width and excellent uniformity, etc., and useful as a filter base material, etc., by producing fiber streams with a specific melt-blow spinneret and collecting and laminating the fiber streams on a collection net placed below the spinneret and moving in a specific manner. CONSTITUTION:A definite amount of a molten thermoplastic resin is supplied to a spinneret 2, extruded through a row of a number of orifices of the spinneret and drawn and split with highspeed gas stream blasted from a gas-blasting slits. The obtained fiber streams 4 are collected and laminated on a collection net 5 to obtain the objective nonwoven fabric. The collection net 5 is reciprocated in the direction perpendicular to the arranged direction of the orifices and, exclusively when the collection net 5 is positioned at the end of the reciprocation motion, the net is moved by the distance L defined by formula [L is moving distance of the collection net (mm); N is width of the spinneret (mm); C is >=1] in the direction same as the arranged direction of the spinning orifices.

Title: Apparatus for measuring pressure pulsation
Inventor: KAWADA YUTAKA
IPC: G01L19/02
Filed: 1986-03-27
Abstract: PURPOSE:To take out a true pressure pulsation signal, by subtracting the vibration detection signal taken out by a vibration detection sensor from the pressure pulsation measuring signal taken out by a pressure pulsation measuring sensor. CONSTITUTION:A pressure pulsation measuring sensor 4 is mounted to the opening part of a boss 3 and a vibration detection sensor 5 is connected to the case of the pressure pulsation measuring sensor 4 by a clamp 6. Because the diaphragm part of the vibration detection sensor 5 is hollow, said sensor 5 does not respond to pressure pulsation and picks up only the pressure pulsation measuring sensor 4. The output signals from both sensors 4, 5 are respectively amplified by amplifiers 7, 8. These two amplified signals are applied to a subtractor 9 and the output signal of the vibration detection sensor 5 is subtracted from the output signal of the pressure pulsation measuring sensor 4 to obtain a true pressure pulsation signal from which the piping vibration component is removed.

Title: Suction pressure servo unit
Inventor: TAKEHARA NOBUYUKI
IPC: B60T13/573
Filed: 1983-04-20
Abstract: PURPOSE:To make a servo ratio vary with the strength of step-on force as well as to improve a feeling of braking, by making up a reaction disc with both inner and outer discs in combination, while changing a contact area of the reaction disc in proportion to the strength of the step-on force. CONSTITUTION:An inner disc 18 that is as small as uncontacted with a power piston 4 in terms of size is installed in position between an input rod 10 and an output rod 14. A circular outer disc 20 seated in the power piston 4 is installed in the outside of the inner disc 18 via a clearance 19. In time of poor step-on force acting, since no force of the power piston 4 will act on the inner disc, the step-on force of the rod 10 is transmitted straight to the output rod 14. In contrast with this, when the step-on force is strong enough, the inner disc 18 is deformed by compression, causing the clearance 19 to be closed to nothing, thus it is unified with the outer disc 19 in one. With this constitution, force of the power piston 4 also acts on both discs 18 and 20 so that a servo ratio is heightened.

IPC: G06F13/36
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To logically operate two bus as one bus by connecting them inside a bridge. SOLUTION: When a bus selector 13 is set so as to independently operate two buses 3, 4, an inputted signal from the bus 3 and an inputted signal from the bus 4 are independently inputted inside the bridge 1 and outputted signals from the bridge 1 to the buses 3, 4 are independently outputted as well. When the bus selector 13 is set so as to operate two buses 3, 4 as one bus, inputted signals from the buses 3, 4 are fetched inside the bridge 1 and become the outputted signal to the buses 4, 3. The outputted signals from a host bridge 1 to the buses 3, 4 are outputted to the buses 4, 3 as well. Thus, signals to be asserted to the buses 3, 4 are also asserted to the buses 4, 3 and two buses are operated as one bus.

Abstract: PURPOSE:To increase the pressing strength to a negative electrode plate and prevent the peeling off from the negative electrode plate by applying the partial punching to a metal thin plate with a punch to form tongue-shaped hooking lugs. CONSTITUTION:A punch 4 is driven by a ram not shown in the figure, for example, to press a metal thin plate 3. The punch 4 first punches the metal thin plate 3 with lugs on both sides of its machining face. As the punched quantity is increased, the metal thin plate 3 is punched along the machining face of the punch 4 as shown in the figure. When the punched quantity becomes B (bite quantity) as shown in the figure, the punch drive is stopped, then the punch 4 is extracted. Tongue-shaped lugs are thereby formed on the metal thin plate 3 as shown in the figure. That is, a pair of tongue-shaped lugs which are slantly erected at an angle C and a height H respectively across the connection section W of the metal thin plate 3 and have R on the periphery are obtained. A negative electrode current collecting plate which has the large pressing strength to a negative electrode plate and can prevent the peeling off from the negative electrode plate is obtained accordingly.
