Patent JP-2000240744-A (JP)
Title: Hydraulic tensioner
Inventor: FUJIMOTO NOBUYUKI
IPC: F15B21/044
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To lower the cost while preventing increase of dimension by integrally forming a function for eliminating the excessive pressure inside of a high-pressure oil chamber and a function for leaking the air or the oil inside of a plunger with each other. SOLUTION: When an impact or a load is applied to a plunger 2 in a direction opposite to the energizing direction of a spring 5 for plunger, oil pressure inside of a high-pressure oil chamber 8 is raised. At this stage, air or oil is leaked from an orifice 11A so as to relax the impact applied to the plunger 2, and at the same time, oil pressure equal to the oil pressure of the high-pressure oil chamber 8 is transmitted to an auxiliary oil chamber 14, and when the oil pressure corresponding to the cross section of a sleeve 16 exceeds the energizing force of a spring 19 for sleeve, the sleeve 16 is gradually moved backward. Furthermore when the oil pressure is raised a flow- out port 15 is opened, and the oil is flowed out from the auxiliary oil chamber 14 to an oil reservoir chamber 18 so as to eliminate the excessive oil pressure of the high-pressure oil chamber 8.  The leaked oil and the oil from the flow-out port 15 are flowed into the oil reservoir chamber 18, and discharged from a discharge port 20 so as to be supplied to a chain or the like. With this unified structure, miniaturization is realized.

Title: Electric power steering device
Inventor: MATSUOKA HIROSHI
IPC: B62D5/04
Filed: 1989-02-21
Abstract: PURPOSE:To realize miniaturization by making a worm connected to an auxiliary steering motor drive shaft, transferable in a shaft length direction by giving restitutionability against a predetermined position in the shaft length direction, and by detecting torque which acts on a worm wheel at a steering shaft at a shaft length direction displacement. CONSTITUTION:A worm wheel 23 is put on the output shaft 3 of a steering shaft, and at its outer perimeter, a worm shaft 22 is positioned so that its shaft center may meet at right angles with the shaft center of the worm wheel 23, and meshing is made. The drive force of a motor 5 is transmitted to the end portion on the bearing 24 side of the worm shaft 22 through an electromagnetic clutch 27 by means of serration 26. The other end portion of the worm shaft 22 is inserted into the inside of a displacement detection hole 4. When torque of more than a predetermined strength is added on the output shaft 3, the worm 22 is displaced, and a magnetic core retaining member 30 is also transferred, and a displacement quantity is detected by means of a differential transformer 31. Accordingly, the drive force of the motor 5 can be controlled according to torque, so miniaturization can be accomplished with a simple constitution.

Title: Detecting device for inner-cylinder pressure of internal combustion engine
Inventor: IWATA TOSHIO
IPC: G01H17/00
Filed: 1988-02-24
Abstract: PURPOSE:To enable the implementation of an efficient signal processing being resistive to noise, by inputting an output signal of a piezoelectric type inner-cylinder pressure sensor in the form of a current and by measuring a knock signal from an output signal of LPF. CONSTITUTION:When a charge Q is outputted in accordance with an inner-cylinder pressure from the output of a piezoelectric type inner-cylinder pressure sensor 1, a current of -dQ/dt is outputted from an operational amplifier 51 to a resistance 52 by a feedback control of the amplifier 51. Due to a voltage drop of the resistance 52, an output voltage V1 of the amplifier 51 turns to be V1=-R1.dQ/dt when a resistance value of the resistance 52 is denoted by R1. This voltage V1 of the amplifier 51 is a voltage obtained by subjecting the inner-cylinder pressure to time differentiation. The voltage V is supplied to LPF 53. This LPF 53 attenuates a low frequency component caused by a change in the inner-cylinder pressure and also can output a high frequency component of pressure vibration, with a uniform frequency characteristic. By passing an output signal of the LPF 53 through BPF 54 having a characteristic of a central frequency, a knock signal can be extracted effectively from a pressure frequency component.

Title: Cleaning treatment of waste gas containing nitrogen oxide compound
Inventor: SUGANUMA FUJIO
IPC: B01J21/16
Filed: 1991-01-08
Abstract: PURPOSE:To efficiently remove NOx in a waste gas containing SOx without lowering the activity of a catalyst to be used in an oxidative atmosphere in which excessive oxygen exists and remove incomplete combustion products sometimes discharged by the removal of the NOx. CONSTITUTION:In the presence of hydrocarbons or oxygen-containing compounds (hydrocarbons hereafter) existing in a waste gas or introduced from outside, a waste gas is brought into contact with a catalyst containing transition metal ion-exchanged clays (montmorillonite group, micaceous clay mineral group, kaolinite mineral group, etc.). The catalyst preferentially accelerates the reaction of NOx with hydrocarbons rather than the reaction of oxygen with the hydrocarbons in an oxidative atmosphere and thus NOx in the waste gas is removed highly efficiently. Also, the waste gas after being brought into contact with the catalyst is brought into contact with an oxidation catalyst to remove incomplete combustion products.

Even if the flushing water is increased, this constitution eliminates any splash of the flushing water. This flushing method can be also applied to flushing of a floor face, a wall face, etc., besides the urinal. The flushing can be performed efficiently thereby.
