摘要:
An air bag apparatus in which the appearance of the interface between the portion covering the air bag and portions surrounding it can be improved, the number of components can be reduced, and the assembly process can be shortened. A cover unit covers an air bag, which inflates on a predetermined occasion, consists of a cover which-opens with the inflation of the air bag, and a body for holding the cover. The cover unit is an integrally molded product in which a skin is formed on a substrate, and includes, at the location connecting the periphery of the cover with the body, a breakaway portion along which the cover is separable from the body when the air bag inflates, and a hinge portion for maintaining the connection of the body and the cover. In the breakaway portion, the substrate has a fragile portion, and the skin is separated into two parts at the position of the fragile portion. In the hinge portion, the substrate and skin are continuously formed and extend from the body to the cover.

A beam spot controlling method for controlling the beam-converging position by a light beam from an objective lens on a recording track of a recording medium comprising the steps of (a) rotating a tapered prism having an inclination-imparting portion capable of imparting an inclination to a light beam which enters the tapered prism for changing the inclination of the light beam incident on said objective lens for controlling the beam-converging position by the light beam; (b) causing a light beam to enter the tapered prisms; and (c) causing the light beam exiting from the tapered prism to enter the objective lens, and directing the exiting light beam onto the recording track of said recording medium, and an apparatus for performing the above beam spot controlling method.

A structure for attaching a carpet to a forwardly foldable type of seat back in an automotive seat, wherein the portion of the carpet attached to the rear side of seat back is at its rear surface fixed with a separate hard member with a clearance from the back board of the seat back. This arrangement avoids slackened state of the carpet on the seat back.

A turbine flowmeter includes an impeller rotatably provided within a flow passage through which a fluid to be measured flows and comprising a rotary shaft which rotates together with the impeller, a pair of bearing part having bearing surfaces for axially supporting the rotary shaft, a holding part for holding the bearing part and provided on the flow passage, an oil accumulating space defined by an end portion of the rotary shaft and bearing surfaces facing respective sides of the end portion, an oil accumulating part provided on the holding part and filled with the lubricating oil to be supplied to the oil accumulating space, an oil supplying part for supplying oil to the oil accumulating space which part comprises a capillary part connected on one end direct to the oil accumulating part and communicated on the other end to the space, wherein the lubricating oil is supplied to the space via the oil supplying part from the oil accumulating part by capillarity introduced in the oil accumulating part and the space, and wherein the surface tension of the lubricating oil in the space is equal to or larger than the surface tension of the lubricating oil in the oil accumulating part.
摘要:
An air conditioning apparatus using a refrigerating cycle in which a scroll compressor is used to compress a refrigerant. The scroll compressor is driven by an induction motor. The speed of the induction motor is controlled by a PWM type inverter which produces an AC voltage of variable frequency. A carrier frequency higher than 10 KHz is used to effect pulse width modulation of the AC voltage of the inverter, whereby generation of uncomfortable noise is avoided. A control unit is provided to detect slip of the induction motor and to adjust the detached slip to a predetermined optimum value, thereby avoiding excessive lowering of the speed of the motor which may cause lack of lubricating oil for the compressor.

According to the present invention, a silicon wafer, silicon dioxide wafer or silicon wafer having a silicon dioxide film thereon can be mutually adhered. The procedure for the adhesion is that a refractory metal, such as zirconium, is deposited by sputtering on a flat surface to be adhered, and tightly stacked onto another substrate made of silicon, silicon dioxide or silicon having a silicon dioxide film thereto, and the stacked wafers are heated in an atmosphere of argon containing 4% hydrogen at approximately 650.degree. C. for approximately 2 hours. The heat causes the deposited zirconium to react with the silicon of both the contacting wafers and is converted into a zirconium silicide alloy, which bonds the wafers. If the wafer is silicon dioxide or coated with silicon dioxide, the zirconium reduces the dioxide to produce silicon, which is then alloyed with the zirconium. Refractory metals other than group IVa and group Va elements can adhere silicon to silicon only. Advantages of this adhesion method are: the process is carried out at approximately 650.degree. C., which does not harm fabricated devices; the adhesion withstands temperatures of 1000.degree. C. which are used for fabricating devices; and the processing does not require strict control of the surface conditions. This method can be applied to the process of making SOI, a wafer-scale integrated LSi, or a three-dimensional LSI.
摘要:
A diagnostic system of an air-fuel ratio control device including an O.sub.2 sensor and an air bleed control valve actuated in response to a signal output by the O.sub.2 sensor. When the electric control current fed into the air bleed control valve reaches an upper limit or lower limit and remains at the upper limit or lower limit for a fixed time, the diagnostic system determines that the air-fuel ratio control device has malfunctioned. When the temperature of the engine cooling water is high, a diagnosis is prohibited, to prevent an incorrect diagnosis.

A crosslinking agent constituted by a cyclodextrin clathrate compound of a compound having isocyanate group(s). This crosslinking agent is stable at room temperature and very readily initiates crosslinking. The crosslinking agent is prepared by reacting a compound having isocyanate group(s) with cyclodextrin at 65.degree. C. or below in water, and recovering the clathrate compound from the water.
摘要:
A process for producing a dielectric layer which on a semiconductor layer comprises the steps of forming a layer of oxide of an element selected from the group consisting of tantalum, titanium, niobium, hafnium, yttrium, zirconium, and vanadium on the surface of the semiconductor layer and heating the semiconductor layer having the oxide layer thereon in an oxidizing atmosphere. The semiconductor layer is thermally oxidized so as to form an insulating layer which comprises oxide of the semiconductor material at the interface between the semiconductor layer and the oxide layer.
