An overcharge preventive device for an automotive battery charging circuit comprises an odorant sensor 6 for detecting the amount of gas generated from the battery 1 during charging (FIG. 3). A detector circuit 7 generates an overcharge detection signal when the amount of gas exceeds a predetermined level. In response thereto, the display or monitor lamp 8 displays the overcharged state, and the interruptor circuit 9 separates the alternator 5 from the battery 1. Alternatively, when the automobile has an audio device such as radio, a voltage detector 19 detects the voltage across the load 4 and outputs a signal when the voltage exceeds a predetermined level, an alarm signal generator 20 generating an audio signal in response to the output signal of the voltage detector 19, such that an alarm sound or voice is produced by a loudspeaker 17 via the amplifier 16 (FIG. 4).

The apparatus for controlling a damper in an air conditioning system for a vehicle. The damper is used for selectively opening air outlets, and is constructed as a film damper having one end wound on a drive shaft rotatably supported in a casing. The drive shaft is formed as a hollow shaft having an axial bore therein, in which an electric motor with a reduction gear is arranged. The outer body of the motor is fixedly inserted to the shaft, and has an output shaft fixedly connected to the casing, so that a rotation of the motor causes a relative rotation between the motor body connected to the hollow shaft and the outlet shaft connected to the casing. As a result of the rotation of the motor body, the drive shaft is rotated, resulting in a desired movement of the film damper.

A control device in a transceiver suppresses the generation of unnecessary frequency components which takes place when predetermined control steps are repetitively executed under the control of a clock signal. The repetitive period of the predetermined control steps is intentionally controlled not to become constant.

In a method and apparatus for controlling a radio telephone system, a speech channel is established between the slave radio set of a plurality of radio telephone sets and a radio set of a base unit. An intercom switch for selecting intercom performances is provided for respective radio telephone sets. The slave radio sets of the radio telephone sets are turned OFF when the intercom switch is OFF, and transmitters of the slave radio sets of the radio telephone sets are turned ON. Consequently the connection between a wired telephone channel and the plurality of radio telephone sets can be controlled with a single base unit connected to the wired telephone channel.

A known fuel filter is formed by a meshed body in a bag shape made of a synthetic resin while the meshed body is penetrated to form a fuel passage which is open toward the inside of the meshed body. The known fuel filter is attached to a portion adjacent to a bottom of the fuel tank for preventing water and a dust accumulated inside the fuel tank from being drawn inside the fuel filter. However, the known fuel filter has the fuel passage penetrating the central portion of the meshed body so that the degree of freedom of attachment is reduced. On the other hand, a fuel filter according to the present invention comprises a piece of meshed body being folded double, an outer flange and an inner flange respectively having a fuel passage and being connected to each other from the inside and the outside of the doubled folded portion, a swollen supporter provided integrally with or separately from the inner flange. The peripheries of three sides of the meshed body are welded and the fuel pipe is connected to the outer flange. With such an arrangement, the fuel pipe can be installed along the side wall of the fuel tank. The swollen supporter may comprise a flat plate and a projecting wall projecting from the flat plate which crosses a longitudinal direction of the flat plate while a trimming hole is provided at a central portion of the flat plate and the swollen supporter is cantilevered so that the swollen supporter can be swung vertically.
摘要:
A plasma forming electrode used in pairs disposed in mutually facing spaced parallel relation in a reduced pressure treating chamber, and between which a radio frequency current power is applied to produce a plasma, is formed from preferably highly pure aluminum or an aluminum alloy, and has a chromic acid anodic surface film layer thereon. It has greatly improved durability when used for plasma treatment in the presence of fluorine containing gas.

In a method for operating a washing machine, the accumulated value representative of the number of washing works done in the washing machine is updated and stored in a nonvolatile memory each time such washing work is done. The accumulated value is compared with a predetermined value representative of a tolerance limit number of washing work of such washing machine. In case that the accumulated value is beyond the predetermined value, the washing machine is made inoperative. The user may be informed visually and/or acoustically of the inoperative condition of such washing machine.

A pressure water absorption inhibitor for lightweight aggregates which comprises an aqueous dispersion of a polymeric substance having a viscosity which permits the aqueous dispersion to enter the fine pores in the surface layer of a lightweight aggregate and which dispersion is capable of being thickened to a viscosity of not less than 50 times the viscosity before thickening by elevation of the pH.
摘要:
A portable unit that may be called from a base station through a radio control channel by a succession of terminating call signals that is sent through the control channel from the base station to the portable unit for a first or restricted time duration (T.sub.1), selected in consideration of a battery saving period of a battery saving operation carried out in the portable unit. Within the battery saving period, the portable unit is put into transient active and inactive states during a first time interval and a second time interval, respectively. Selection is made so that the first time duration is longer than the second time interval to receive at least one of the terminating call signals within the first time duration in the portable unit. The base station monitors an acknowledgement signal for a second time duration (T.sub.2) after the lapse of the first time duration and interrupts the control channel when the acknowledgement signal is not received within the first and the second time durations. In the portable unit, the battery saving operation is released when the presence of the terminating call signals is detected by a squelch circuit.
摘要:
A process for producing an alkenylsilyl group-containing polymer compound, comprising polymerizing a vinyl monomer compound containing an alkenylsilyl group-containing styrene compound represented by General Formula (I): ##STR1## wherein R.sup.1 represents hydrogen atom, methyl group or ethyl group; R.sup.2 and R.sup.3 may be the same or different and each represent an alkyl group having 1 to 3 carbon atoms or phenyl group; and n is an integer of 0 to 4, by using an organic metallic compound as an initiator, wherein the polymerization is carried out in the presence of N-methylpyrrolidine.There can be obtained a monodisperse alkenylsilyl group-containing high molecular compound in which only the unsaturated bond in the styrene moiety of the compound of Formula (I) has been predominantly polymerized.
