Title: Cards and dice game to develop public speaking ability
Inventor: KLASSEN DWAYNE
IPC: G09B19/04
Filed: 1997-02-12
Abstract: A cards and dice game to develop public speaking ability is disclosed.   The game provides a single die which is rolled to determine the order of play.  Timing and grammar judges are selected.  The players take turns as speaker in sequence.  Each player begins each turn by selecting a card from a stack of cards, wherein each card has a plurality of speaking topics on the card.   The player then rolls the die to determine which speaking topic on the card is to be used.  The player receives 1 point for every second of speech.   A maximum speaking time of 3 minutes and 180 points is allowed.  Points are deducted by the grammarian for speech fillers such as "ummms" and "ahhhs", and for pauses.  Ten points are lost where the speaker strays from the topic.

Title: High frequency heating device which is safe when its exterior is removed
Inventor: KAWAMURA KAZUHIKO
IPC: H01H9/22
Filed: 1997-07-17
Abstract: A high frequency heating device according to the present invention has a switching member screwed into a screw hole formed in a flange and thus fixed to the exterior.  When the exterior is fixed to the body, a through hole formed at that portion in the rear plate of the body through which the switching member passes is too large for the switching member.  Thus, while switching member is fixable to the exterior, the switching member cannot be fixed to the body onto which the exterior is not mounted.  Thus, a high frequency heating device can be provided, wherein an exterior switch more surely keeps the power supply circuit open when the exterior is removed.

Abstract: An apparatus for analyzing telephone billing data to produce augmented billings and reports on calls to classes of telephone numbers selected by the user, such as to calls not on a list of authorized telephone numbers or calls not fulfilling some other predetermined criterion, includes data reading, selecting, and storing means capable of obtaining telephone directory and billing data in machine manipulatable form, comparing means for finding matches between sets of data as well as tracking failures to match, and data combining and outputting means for producing useful reports. External directory information database searching means are provided for matching billing data not matched with the internally stored directory data. Means are also provided for creating a secondary directory of data extracted from previously billing data to increase the efficiency of processing of subsequent billing data sets. The foregoing is a description of a specific implementation of a more general apparatus and method for reading data from at least two sources of input data containing information organized in a known manner or in a manner ascertainable from the data itself. If necessary, the data are converted to a machine manipulatable form (e.g. from a scanned image to character codes). Data of interest are selected and stored into mass storage having a predetermined structure organized into records having fields for preselected data types. The records from each input data source are stored in separate sets of records in mass storage. The stored records are then processed to produce a resulting output set of data records. Processing may comprise combining selected data from records in the input data sets that match according to a preselected criterion and flagging records in one data set that do or do not have matches in one or more of the other input data sets.

Title: Progressive power multi-focal lens
Inventor: KITANI AKIRA
IPC: G02C7/06
Filed: 1996-09-19
Abstract: A progressive power multifocal lens by which a substantially good "broad field of view" can be obtained for an eyeglass wearer without increasing time and cost required to produce the prescribed surface thereof. This progressive power multifocal lens belongs to a group of progressive power multifocal lenses designed under a certain rule in such a manner that fundamental elements such as a far vision power measuring position F and a near vision power measuring position N thereof meet a common wearing object. Further, in the case of this lens, a surface refractive power (in units of diopters) at the far vision power measuring position F is employed as a base curve (Bi). Moreover, a difference in surface refractive power between the far vision power measuring position F and the near vision power measuring position N is employed as an addition Di (in units of diopters). Furthermore, let W(Di, Bi) denote a width of a region in which values of a surface average additional refractive power along a horizontal section line extending below the near vision power measuring position N are not less than Di/2. In such a case, when arbitrary two progressive power multifocal lenses, whose additions are Da and base curves are B1 and B2, respectively, are extracted or selected from the group of the progressive power multifocal lenses, the following relation holds for B1>B2 W(Da, B1)> W(Da, B2).
