Filed: 1993-09-29
Abstract: PURPOSE:To miniaturize a solenoid and provide a compact flow control valve as a whole by providing a diahragm covering an opening on the fluid flow passage side and separating from the fluid flow passage and a capsule enclosing liquid having a movable member in the operating direction of a plunger. CONSTITUTION:At electrifying a solenoid 26, a movable plunger 30 is attracted toward a fixed plunger 28. A valve stem 32 presses a bellows 48. Fluid is filled in a capsule 34 enclosing liquid, and the pressure applied on the bellows 48 also acts on a diaphragm 46. The diaphragm 46 is deformed toward a fluid flow passage on the outflow side so as to close the fluid flow passage on the outflow side. In this flow control valve, the force of the solenoid required for closing the fluid flow passage 20 becomes smaller compared with a customary one. Namely compared with the customary one, the fluid flow passage 20 can be closed by the solenoid force of (effective area of bellows/effective area of diaphragm).

Abstract: PURPOSE:To prevent the etching of organic coating and thus prevent the increase in contact resistance by forming a first opening in an organic coating, applying an insulating film over the coating, forming a second opening in the first opening, and applying another insulating film to cover the organic coating completely. CONSTITUTION:A lower wiring layer 2 is formed on a semiconductor substrate coated with a first insulating film 1, and a second insulating film 3 is overlaid. An organic coating 4 is applied to the film 3 and patterned to form a first opening 7A above the lower wiring layer 2. After a third insulating film 5 is formed over the surface including the opening 7A, the third and second insulating films 3 and 5 are etched to form a second opening 8A in the first opening 7A. A conductive film is formed over the whole surface including the opening 8A and patterned into an upper wiring layer 6. This keeps the organic coating 4 unexposed and thus protects its sides against etching, thereby eliminating the increase in contact resistance.

Title: Control device for traveling at constant speed for vehicle
Inventor: KATO KUNIO
IPC: B60K31/00
Filed: 1994-10-28
Abstract: PURPOSE:To provide a constant speed traveling control device for a vehicle which obviates an expensive sensor, provides less load on a control circuit, and suppresses the undershoot after the temporary acceleration. CONSTITUTION:When the temporary acceleration is made by a driver during the constant traveling control, it is detected by a simple method indicated in steps 4201, 4203. The judgement of the return from the temporary acceleration is also made by that the skip vehicle speed Vsk is not greater than the stored vehicle speed Vm (Vsk<=Vm), or that the present vehicle speed Vn is not greater than the stored vehicle speed Vm (or Vm + the specific speed alpha) (step 4209). Thus, an expensive sensor such as a throttle opening sensor can be obviated, and no complicated operation based on the throttle opening value can be omitted to prevent the load on the control side from being increased. A constant speed traveling control device to suppress the undershoot when returned from the temporary acceleration can be carried out with a simple constitution.

CONSTITUTION:Through an engine mount absorbs vibration of an engine by deformation of a rubber wall 2, liquid-crystal substance in a room 4 moves through an orifice 6 up and down a partioning plate 5 due to variation of volume of the room 4, so that this flow resistance enhance enhances the efficiency of vibration absorption. Accordingly, by on/off in the application of voltage to electrodes 61, 62 or by regulating the applied voltage, a rheological property, such as elastic modulus, of the liquid crystal, is varied, so that the flow resistance is varied. The vibration attenuation characteristic can thus be varied, so that efficient vibration absorption according to the vibration condition becomes possible. In this case, by a suitable relation between frequency of the engine vibration and frequency of voltage applied to the electrodes 61, 62, and the vibration adsortion is possible in a wide range of temperature or frequency, or at lower applied voltages.

Abstract: PROBLEM TO BE SOLVED: To prevent the link between multimedia documents from being broken by document correction or the like. SOLUTION: A document 51 on the calling side doesn't hold the physical position itself of information (information A) to be called in a document 52 but holds the document class of the document 52, the keyword indicating information to be called, and the keyword class of this keyword instead and gives a message, on which these information are put, to a document message broker 59 when necessary. The broker finds it from the given document class that the message should be sent to the document 52. The document 52 refers to the keyword class in the message to determine a conversion table to be used and uses the keyword to retrieve this conversion table and obtains the position of information A. Even if the position of information A is changed after the link is connected, data in the conversion table in the same document is only corrected to maintain the link.
