摘要:
In a pressure vessel (1) comprising a resin liner (2) provided with a tubular extension (22) defining a through hole therein for receiving and expelling the gas or liquid, a tubular member (100, 200, 300) fitted in the through hole of the tubular extension, a mouthpiece (4) threaded into the tubular extension, a fiber reinforced resin layer (3) placed around an outer surface of the resin liner, and a valve (60) fitted into the central bore of the tubular member, the valve include a section (62) having a smaller outer diameter than an opposing inner circumferential surface of the tubular member defining a gap between the valve and tubular member, and a resilient seal member (80) is placed in the gap. The tubular member is made of a material such as metallic material which is stiffer than the resin liner. Thereby, the resilient seal member is interposed between the tubular member and valve which are both highly stiff or free from deformation when the interior of the pressure vessel is placed under various pressure conditions so that the sealing performance of the resilient seal member can be ensured under all pressure conditions.

A multilayer injection molding machine manufactures a molded product formed of a plurality of layers of resins or colors by press fitting resins from a core layer injection unit and a skin layer injection unit to a cavity party formed by pressing and clamping a moving metal mold to a fixed metal mold fixed to a support member. The multilayer injection molding machine is formed by integrating a connecting device body interposed between the fixed metal mold and the support member so as to support the fixed metal mold to the support member and an injection unit connecting device provided on the connecting device body and having a plurality of resin passages allowing the cavity part to communicate with each injection unit.
摘要:
A disc apparatus in which recorded data can be correctly reproduced despite occurrence of a low-reliability area at a specified position on a disc on which synchronization signals are recorded. A comparison error signal between the playback RF signals read out from a disc 100 and channel clocks PLCK enters a VCO 15 via a phase/frequency comparator 12. A VCO 15 generates PLCK at a frequency corresponding to the voltage of the comparison error signal. A data detection unit 16 takes out data from the playback RF signals. If a Sync pattern detection interpolation unit 17 detects the Sync pattern correctly from this data, the above comparison error signal is directly fed to the VCO 15 and, if otherwise, the sample-and-hold unit 14 holds the voltage of the comparison error signal by control signals from a controller 20. At this time, interpolation of the Sync patterns by the Sync pattern detection interpolation unit 17 is discontinued.

The invention relates to a power source circuit in which an output of a power source battery is converted by a voltage regulator constructed by a predetermined voltage regulating system and is output, an output voltage is divided by a resistance controller whose voltage dividing resistance value can be discontinuously adjusted, the divided voltage is input to the voltage regulator, and thereby controlling an output voltage, wherein means for controlling a voltage changing speed of a resistor is connected in parallel with a predetermined resistance element of the resistance controller. With the above construction, a voltage drop and a deterioration of voltage regulating efficiency which easily occur in the case of changing the output voltage from a low value to a high value in a stepwise manner are reduced. Then, the life of battery is prolonged and, further, an erroneous warning of the battery life is prevented.

An AFC circuit has a tuning circuit including a first variable capacitance element and a pair of series connected inductive elements. Switch means are connected between ground and a point between the inductive elements for alternatively operably connecting one or both of the inductive elements in parallel with the first variable capacitance element to switch the tuning circuit between a higher frequency range and a lower frequency range. The AFC portion of the circuit comprises a second variable capacitance element which is connected in parallel with the first variable capacitance element. In order to improve the sensitivity of this circuit, a means is provided for capacitively coupling the second variable capacitance element to a point between the inductive elements. As a result, substantially equal AFC ranges are obtained whether the circuit is tuned to the higher or the lower frequency range.
