Abstract: A radio telephone system is comprised of a communication network, a cordless telephone apparatus and a plurality of public radio base stations, both being connected to the communication network, and a handset unit of the cordless telephone apparatus is capable of exchanging messages with the plurality of public radio base stations. The cordless telephone apparatus is provided with a control-data storage unit for storing data of controlling handsets unit belonging to the cordless telephone apparatus. The control-data storage unit stores data each comprising a combination of an extension number and a phone number of a handset unit. The cordless telephone apparatus judges whether a handset unit to be reached is in a service area of the apparatus, when the handset unit is called from another handset unit of the cordless telephone apparatus.

Abstract: A switch which provides different switching inputs by pushing different operating portions of a single operating button is disclosed. The switch comprises an operating button the periphery of which has a plurality of operating portions, a support provided at the center of the rear portion of the button, a casing having a plurality of through-holes defined opposite the operating portions of the button, and a plurality of operating shafts received in the through-holes. The rear surface of the button has bosses in and out of point-contact with the operating shafts. Although the bosses are rotated about the support for the button, the operating shafts receives simple axial forces. This secures good operation of the switch.

Abstract: This application discloses a film wiring board for directly mounting an electronic parts such as an IC chip, on which a protective film having an opening can be formed in one step by a screen printing. This film wiring board has wiring patterns including connection pads and lead wires. Connection electrodes of the IC chip are connected to the connection pads via soldering bumps. Since the width of each of the lead wires is comparatively small at 10 .mu.m-30 .mu.m, the once molten solder when the connection is done is kept on the corresponding connection pad by the surface tension and is prevented from flowing from the connection pad to the corresponding lead wire. Therefore, since the opening of the protective film need not have a function for stopping the flow of the solder, there may be no problem if the opening is comparatively enlarged.

Abstract: An automatic melody composer composes a melody on a phrase by phrase basis. A phrase database storage stores data of many and various phrases. A generating index database storage stores records of music generating index. Each record describes or indicates appropriate phrases in the phase database and how melody is modified or developed in moving from one musical time unit to another. A decoder selects an index record from the generating index database, retrieves, from the phrase database, phrase components according to the index record, and combines them into a phrase. Thus, the composer quickly provides a natural melody formed with a chain of phrases without requiring complicated data processing.

Abstract: In a liquid crystal display device, to improve the contrast, the frame frequency is raised by scanning the scanning electrodes of the liquid crystal display panel a plurality of times during one field interval of the video signal. The scanning electrodes are divided into two groups, which are scanned alternately. An image memory is provided to store video signals. In scanning the liquid crystal display panel, the video signal from the video signal supplying source and the video signal read from the image memory are alternately supplied to the liquid crystal display panel. The image memory stores only part of the video signal such as the video signal for every other horizontal scanning period or the signal consisting of the most significant bit only, not the entire video signal.

Abstract: A liquid crystal display device includes a pair of substrates facing each, first and second electrodes formed on each inner surface of the substrates and arranged so that they are crossed and face each other, first and second aligning films covering each inner surface of the substrates and said first and second electrodes and provided with an aligning treatment in a direction respectively, and a liquid crystal member sealed between the substrates by a seal layer. The liquid crystal layer is twistingly aligned by the aligning force of said first and second aligning films at an angle of approx. 230.degree. to 250.degree., and has a positive dielectric anisotropy. The liquid crystal layer includes a liquid crystal member having a dielectric constant ratio .DELTA..epsilon./.epsilon..perp. defined as a ratio of the dielectric anisotropy .DELTA..epsilon. and the dielectric constant .epsilon..perp. with the direction orthogonal to the liquid crystal molecule axis of 2 or less, and a elastic constant ratio K.sub.

Abstract: In a tape printer apparatus, tape cassettes containing tape members of different widths are selectively mounted, and input printing data is printed on the tape member of the mounted tape cassette. The tape cassettes are provided with notches indicating the widths of the contained tape members. The presence or absence of the notch of the mounted cassette case is detected by ON or OFF of switches disposed in a cassette mounting portion of an apparatus case. Based on a result of this detection, the tape width is determined, and a printing matching with the tape width is performed.

Abstract: An electrostatic recording apparatus includes a developing agent carrier member provided to extend along a predetermined path. A developing agent convey unit conveys a developing agent along the surface of the developing agent carrier member. The developing agent carrier member has a step in a developing agent convey direction of its surface. A plurality of recording electrodes are aligned on an upper surface of the step of the developing agent carrier member and spaced apart from each other with gaps therebetween in a direction perpendicular to the developing agent convey direction, and project uniformly from the step. An opposite electrode is disposed to oppose the plurality of recording electrodes. A leaf spring member supports at least portions of the plurality of recording electrodes projecting from the step and can swing the projecting recording electrodes in directions to approach to and to separate from the opposite electrode.
