Patent CH-627336-B (CH)
Inventor: MORI SHIGEO
IPC: G04C21/02
Filed: 1977-09-01
Abstract: An electroacoustic transducer particularly for small small-sized portable equipment such as a wristwatch comprises a first vibrating plate which is vibrated by means of an electromagnet and a second vibrating plate which is coupled with the first vibrating plate by an airtight space which acts as an air spring. The first and second vibrating plates have different natural resonant frequencies so that the vibration system comprising the two vibrating plates and the air spring coupling them with one another forms a vibration system having two resonant frequencies. A resonant air chamber superposed on the second vibrating plate has a sound radiating port and has a resonant frequency between the two resonant frequencies of the vibration system comprising the first and second vibrating plates and coupling air spring. The electroacoustic transducer thus responds to a considerable range of frequencies.
Patent DE-1212215-B (DE)
IPC: H01L21/00
Filed: 1962-07-11
Abstract: 968,106. Semi-conductor devices. GENERAL ELECTRIC CO. Ltd. July 4, 1962 [July 12, 1961], No. 25243/61. Drawings to Specification. Heading H1K. A semi-conductor device incorporates a wafer containing a plane PN junction parallel to the main faces of the wafer and formed between a first layer of one conductivity type and a second layer of the opposite conductivity type, the net significant impurity concentration in said first layer being greater than that in said second layer: there is present on the surface of the wafer a net electrostatic charge which is of the same polarity as the majority carriers in said first layer, and the surface of the wafer is bevelled at least in the region where the PN junction meets the surface in such a manner that the surface of the second layer contiguous with the junction makes an included angle of between 170 degrees and 180 degrees with the plane of the junction. It is stated that the surface charge on germanium devices is apparently dependent on the nature of the surrounding atmosphere, electronegative gases such as oxygen or ozone producing a negative surface charge while water vapour produces a positive arc. Thus the desired surface charge may be obtained by encapsulating the device in a suitable atmosphere. The charge on silicon devices is much less sensitive to the surrounding atmosphere and is normally positive. A silicon wafer for a silicon controlled rectifier, Fig. 5 (not shown), is also described in Specification 968,353, and may be produced by a lapping method also described in Specification 968,105. An etching method for producing the bevel is described with reference to the manufacture of a diode rectifier. A silicon wafer of N- type conductivity is provided with an allround diffused surface layer of gallium doped P-type material. One face is lapped so that the wafer contains only a single PN junction. A disc is cut from the slice and a circle of wax deposited on its P-type face leaving an annular outer region unmasked. The wafer is immersed for 5 to 9 minutes in a " slow " etch containing specified amounts of nitric, hydrofluoric, acetic, and phosphoric acids. This etch preferentially attacks the low resistivity P-type material and forms a shoulder such that the newly-formed surface subtends an angle of about 5 degrees with the plane of the junction. Ohmic contacts are applied in a conventional manner and the diode hermetically sealed in an envelope.

Granted: 1985-01-09
Abstract: A web of crepe paper, thin plastic foil or like material convoluted into a roll has an outer side which is provided with a continuous coat of adhesive. Transversely extending, uniformly spaced weakened portion in the form of perforations or slits are formed in the web, and layers of a material which does not adhere to the adhesive are applied to the web. Such layers are applied to the inner side of the web so that they flank the weakened portions and allow for rapid engagement of the leader of the web by two fingers when the user wishes to remove one or more sections or panels between neighboring weakened portions. The roll can be used for the cleaning of garments or for analogous purposes and can be made in an apparatus wherein the application of layers of non-adherent material precedes or follows the making of weakened portions. The length of each layer, as considered in the longitudinal direction of the web, is a small fraction, preferably less than one-third, of the distance between two neighboring weakened portions.
