Title: Apparatus for measuring elongation, compression, and similiar forces in structural elements or in machine parts
Inventor: STARKE EMIL JR
IPC: G01B7/16
Filed: 1991-07-18
Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus is described for measuring elongation, compression, and similar forces in structural elements or in machine parts, the lengths of which can be varied.  In order to detect even small changes in length in structural elements, using a transportable apparatus, without having to intervene essentially in the structural element, the apparatus has a housing on which two blades which are spaced apart are arranged.  Of these, one blade is connected rigidly to the housing and the other blade is supported in the housing so as to be moveable or deflectable in the direction of the change of length of the structural element that is to be measured.  Within the housing there is a raising and lowering mechanism which, when the apparatus is lowered, renders attachment magnets active, the magnets then attaching the housing to the structural element that is to be measured by means of magnetic attraction when, at the same time, the tips of the blades dig into the surface of the structural element to be measured.  In the raised position of the apparatus, the attachment magnets are rendered inactive and the measuring tips are raised from the surface that is to be measured.

Title: Tape cassette
Inventor: SUZUKI KAZUYOSHI
IPC: G11B15/07
Filed: 1991-08-28
Abstract: A tape cassette for use in a tape player includes a cassette case having a main portion with an external size which is substantially the same as that of the case of a different type of tape cassette and an additional portion which extends from one side of the main portion and has a thickness slightly smaller than that of the main portion. An information indicating portion is provided at a lower surface of the additional portion for indicating respective information by whether or not a hole is present at a predetermined position. An information reading member provided in the tape player for determining whether or not a hole is present at each respective predetermined position in the information indicating portion can be located at a position so as not to interfere with the cassette case of the different type of tape cassette. As a result, the information reading member will not hinder the loading operation of the different type of tape cassette into the tape player and the information reading member will not malfunction due to the loading of the different type of tape cassette.

Title: Optical modulator for cancellation of second-order intermodulation products in lightwave systems
Inventor: OLSHANSKY ROBERT
IPC: H04B10/2557
Filed: 1991-12-30
Abstract: OPTICAL MODULATOR FOR CANCELLATION OF SECOND-ORDER    INTERMODULATION PRODUCTS IN LIGHTWAVE SYSTEMS            ABSTRACT      Optical communication methods and apparatus are disclosed for transmitting two or more optical signals with different optical carrier frequencies on a single optical fiber with high spectral efficiency.  Each optical carrier is typically modulated with multiple modulated subcarriers.  In one embodiment, an optical phase modulator provides cancellation of second order intermodulation products in each optical signal, thereby permitting the optical carrier frequencies to be spaced by 2fmax, where fmax is the maximum modulation frequency.  In another embodiment, a single wideband optical phase modulator provides cancellation of second order intermodulation products and one signal sideband, thereby permitting the optical carrier frequencies to be spaced by fmax.

Title: Lcd controller, lcd apparatus, and information processing apparatus

Abstract: LCD CONTROLLER, LCD APPARATUS, AND INFORMATION             PROCESSING APPARATUS                            ABSTRACT            In conventional LCD apparatus,  the last line of data tends to appear in the first line.  This tendency causes a serious problem in the case where the lower half portion of the LCD panel  is driven separately from the upper half portion, because  the  first  line  of  the  lower  half  portion  is positioned in the center of the whole panel.  The reason why the last line data appears in the first line is that the last line data, which is continuously applied to the data electrodes during the vertical blanking term,  hinders the quick  changing  in  potential  on  the  data  electrodes  in response  to the first line data of the following frame. According to this invention, this disadvantage is eliminated by pre-charging the data electrodes with the data of the first  line  of  the  following  frame  during  the  vertical blanking term.

Abstract: In the case of moulds for continuous casting of polygonal billet cross-sections, more particularly with a square or hexagonal cross-section, the mould cavity (6) can have one shape at the pouring-in end (4) and a different shape at the billet outlet end (5). The aim, by controlled shaping of the billet cross-section inside the mould, is to improve the cooling of the crust of the billet, in order to improve the quality of the billet and also increase the speed of casting. To this end, it is proposed to provide a cross-sectional enlargement (7) in the form of a bulge (9) in each peripheral portion of the mould cavity (6), and the width (10) of the bulge (9) in the direction (11) of advance of the billet, at least along a part (12) of the length of the mould cavity (6), decreases in such a way that the billet cross-section changes shape in transit through the part length (12) of the mould cavity (6).

Title: Apparatus and system for the self-dosing of a liquid medicine
Inventor: TSUJIKAWA HAJIME
IPC: A61M5/168
Filed: 1992-06-30
Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus comprises a device or reservoir which consists of a chamber formed in a casing for receiving a liquid medicine to be self-dosed by a patient, with an inlet and outlet ports formed to communicate with the chamber free from leakage of the medicine.    The device further comprises a piston fitted liquid-tightly in the chamber, a push button attached to and actuating the piston and capable of being pressed by the patient a desired number of times corresponding to an amount of dosed liquid medi-cine, and a spring urging the piston towards its home position.    With the patient's hand being removed from the button, the spring forces the piston backwards to its home position and a resulting negative pressure causes a subsequent smooth refilling of the chamber.    The apparatus of such a simple structure manufactured at a lower cost can be employed in an integrated system for the self-dosing of the liquid medicine.
