An electrode terminal structure for a polymer piezoelectric element is provided. The polymer piezoelectric element comprises a polymer piezoelectric film and a pair of electrode films formed on both sides of the piezoelectric film. A conductor plate and an insulating plate are successively disposed at a part near the periphery on one surface of the polymer piezoelectric film element. The thus stacked part is sandwiched between a double-layered conductor plate and the entire stacked structure is pressure bonded to form the above-mentioned electrode terminal structure.

An electroconductive film having moderate transparency and electroconductivity and excellent mechanical properties inclusive of a good tear strength is provided through a process wherein an electroconductive fiber is dispersed over a thermoplastic resin film, and the thus formed loosely laminated sheet is hot-pressed between a pair of rollers having temperatures above and below the softening point of the thermoplastic resin film, at least one of the rollers being surfaced with an elastic material. The electroconductive film is suitably used as a packaging material for shielding electromagnetic wave.

Fast data patterns with desired edge positions are provided. A pattern generator (PG) circuit 10 stores and provides data patterns and respective position control data. A delay circuit 16 delays a clock CLK to produce a position control clock according to the position control data. An output flip flop 18 provides the data patterns following to the position control clock. The position of the clock is controlled as an operation reference of the data pattern and, as a result, controls the edge positions of the output data pattern.
摘要:
A pyroelectric infrared detector or infrared ray receiving element comprising a plurality of pyroelectric operating areas, utilizing one of the operating areas as an infrared radiation detection area having a light-transmissive surface electrode. The electrical signal produced in the signal detection area is compensated by an electrical signal produced in another pyroelectric operating area having a light-reflective surface electrode. Temperature drift and noise due to vibration are drastically reduced through the compensation.

In a disc changer in which any one is selected from a set of disc-shaped recording media (2) stored in a disc compartment (3) and signals are written and/or read to and/or from the selected disc-shaped recording medium (2), resin layers (192), (194) and (195), softer than the disc-shaped recording medium (2) in a recording and/or playback apparatus (6) are formed on a pair of disc holding members (89) holding the selected disc-shaped recording medium (2) rotatably while chucking the latter and a disc tray (193) on which each of the disc-shaped recording media stored in the disc compartment (3) is placed. The resin layers assure to prevent the disc-shaped recording medium (2) from being damaged due to contact with the disc holding members (89) and disc tray (193).

A process for the production of a polyethylene terephthalate film characterized by carrying out heat setting after biaxial elongation so that the heat set temperature and heat set time may satisfy the following relations:______________________________________ heat set temperature 140-213.degree.C. log t .gtoreq. -0.14T + 10.99 heat set temperature 213-223.degree.C. log t .gtoreq. -0.14T + 30.8 heat set temperature 223-255.degree.C. log t .gtoreq. -0.0186T + 3.73 ______________________________________ in which T is a heat set temperature (.degree.C.) and t is a heat set time (min.), and thus obtaining a cleavage-free film.
摘要:
A pulse delay circuit induces lager jitter to faster input reference pulse trains than before. A buffer receives a reference pulse train and provides non-inverted and inverted pulses. Low pass filters (LPF) and comparators receive the non-inverted and inverted pulses from the buffer and provide pulses having delayed leading and trailing edges. Dividers divide the delayed pulses by 2 to produce the respective pulse trains having a half frequency. An XOR gate produces an exclusive OR of the delayed and divided pulse trains to provide a pulse train having delayed leading and/or trailing edges relative to the reference pulse train. If the delays by the LPFs and comparators are changed, the output pulses from the XOR gate have jitter.

A jitter inducing circuit receives a reference pulse train and induces desired amounts of jitter to the rising and/or falling edges of the pulses. First and second delay blocks 16 and 18 alternately delay the selected edge or edges of the provided reference pulse train interval by preset delay times for every interval. A signal composer 46 composes the outputs of the first and second delay blocks 16 and 18. A delay time setup circuit controls the delay times of the delay blocks 16 and 18. The delay times may change for each interval as a function of time so as to trace a desired function such as a sinusoidal or triangular function.

A time switch for starting and stopping an electric appliance at set times comprises an electric timer, a display housing a display for the set times, and a switch housing having a concave. The switch housing has input terminals, output terminals, and a switch unit for connecting and disconnecting the electric appliance to and from an power source in accordance with an output from the timer. The time switch includes a coupling member for connection of the display housing to the switch housing. The coupling member comprises a cylinder through which lead wires extends between the timer and the switch unit. The coupling member is movably supported to the switch housing along a center axis of the cylinder so that the display housing can move between a normal position where the display housing fits within the concave and an extended position where the display housing projects out of the concave. The coupling member is rotatably supported to the switch housing such that the display housing can rotate about the center axis of the cylinder at the extended position. This time switch presents an advantage that it is easy to check the set times on the display irrespective of installation angle of the time switch to a switchboard or the like.

There is disclosed a detergent composition containing, as an essential ingredient, at least one member selected from three types of .alpha.-sulfo-fatty acid derivatives as represented by following formulas (1), (2) and (3): ##STR1## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each an alkyl group or an alkenyl group, each having from 6 to 24 carbon atoms; R.sub.5 is an alkyl group having from 1 to 4 carbon atoms; M.sub.1, M.sub.2, M.sub.3 and M.sub.4 are each a hydrogen atom or a cation capable of forming a salt; AO is an oxyalkylene group or a polyvalent alcohol residue; and p, m and n are each a positive number. The detergent compositions are very low in irritability to the body and have a low critical micelle concentration and a low Krafft point. Further, they are highly soluble in water and they can be used in the form of powder or liquid.
