Title: Pump system with automatic flow control valve
Inventor: CHIBA MINORU
IPC: F04D15/00
Filed: 1977-11-16
Abstract: PURPOSE: To control the discharge flow rate of a centrifugal pump within the rated level by providing a flow control valve in the discharge piping of the pump for automatic control of the discharge pressure.  
     CONSTITUTION: The pressure in a piping 6 is lead to a cylinder 14 via a pilot piping 28 and is exerted on a pressure receiving surface A 1  of a piston 20 while the pressure of a piping 7 is exerted on a pressure receiving surface A 2  of a piston 19 whereby the resultant force of the forces acting on the pistons 19 and 20 pushes up a valve stem 17 resisting against a spring 21 to open a flow passage of a flow control valve 3. When K is the spring constant of the spring 21 and δ is the deflection: Kδ={A 1 (H 1 +H 2 )+A 2 H 2 }/ρ. When H=H 1 +H 2 : Kδ=(A 1 H+A 2 H 2 )/ρ whereby the flow passage area of the flow control valve 3 increases or decreases corresponding to the value of (A 1 H+A 2 H 2 ). Since A 1 <A 2 , the flow passage area of the flow control valve decreases when H 2  is lower than predetermined level and balances at the point where the total head H 1 +H 2  is larger than the rated head.

Title: Optical disk reproducing device
Inventor: SATOU MICHINORI
IPC: G11B7/085
Filed: 1993-06-08
Abstract: PURPOSE:To shorten a time for reading index information by eliminating reproducing an index information part already finished to read. CONSTITUTION:A reading position of an optical pickup 12 is moved to a read-in- area of a laser disk 11 by a pickup control section 13 based on a sub-code compounded by a read-in-area reproducing means 15 and a decoding section 14. Next, a track means 17 reads a track from a sub-code decoded by the decoding section 14 in reproducing a signal in the read-in-area and stores it. At the time of this reading, an abbreviated reading means 16 makes a first and a second units jump to the outer side by one track immediately after reproduction and makes a third unit reproduce a first unit succeedingly for the same point succeeding three units. And, when the track storage means 17 stores all part required by a track, reading operation of a track is finished. Thus, a time required to read a track can be shortened by using position relation of the direction of circumference in which adjacent tracks deviate by approximately 2.5 units each other.

Title: Jack equipped with wedge mechanism
Inventor: KAEBA NORIJI
IPC: B66F3/30
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To fix a jack-up condition by a jack itself by providing a wedge mechanism between the opening part of a fixed side member having a slide surface for receiving the sliding surface of a wedge and a moving side member. SOLUTION: When an oil pressure is applied from an oil inlet port 66 while a wedge 1 is disengaged, a piston 50 is raised until a guide 59 reaches the guide 68 of a cylinder 6. Accordingly, since an object is jacked up, when the wedge 1 is engaged, the piston 50 is prevented from being returned by the action of the wedge 1 even if an oil pressure is reduced. For returning a jack, first the wedge 1 is made free by applying a little oil pressure from the oil inlet port 66 and, after the wedge 1 is slackened, an oil pressure is applied from an oil inlet port 65. Thus, without continuous application of pressure inside the cylinder 6, or without using other supporting means for the object, a fixed state is held by the jack itself.

IPC: G01P15/18
Filed: 1993-06-08
Abstract: PURPOSE:To allow highly accurate multiaxial acceleration detection using a single acceleration detector by detecting a multiaxial acceleration signal, produced upon application of an AC wave having different frequency or phase to the electrode for a target electrode, in synchronism with the AC wave. CONSTITUTION:Electrodes 11-19 are disposed oppositely to a weight 14 which moves while rocking in response to an applied acceleration. A signal source 40 applies AC waves having different frequencies to the electrodes 17-19 and a converter 41 converts a multiaxial acceleration signal current, detected by an acceleration detector 30, into a DC voltage being fed to a synchronous rectifier 42.
