Patent JP-H08227296-A (JP)
Title: Sound signal processor
Inventor: KAGEYAMA YASUO
IPC: G10L21/007
Filed: 1995-11-21
Abstract: PURPOSE: To give a harmony only to a main melody among them when plural songs such as a duet, etc., are inputted in a karaoke device. CONSTITUTION: When two persons sing, whether or not the harmony is sung excepting the main melody is analyzed. A main melody selection part 23 decides the main melody from plural inputted basic frequencies. When the fact that the harmony is to be given is judged as the result of the analysis decision, a song analysis part 22 instructs the effect for a main melody component separation part 25, and the main melody selection part 23 instructs the frequencies of the main melody. The main melody component separation part 25 separates and extracts only the main melody component from plural inputted song voice signals to input it to a pitch shift part 26. The pitch shift part 26 pitch shifts the main melody component to an interval of e.g. three degree upper, and addition synthesizes with the inputted voice in an addition part 28 to output it to the outside.  Thus, the voice signal giving the harmony only to the main melody is outputted.

Title: Applying method of monolithic refractory
Inventor: KATAOKA MINORU
IPC: B22D41/02
Filed: 1990-11-07
Abstract: PURPOSE:To permit power saving, shorten a time for application and eliminate lamination generated in the applied body of spraying by a method wherein the applied body of spraying is provided with oscillation after applying the spraying or while effecting the application of spraying. CONSTITUTION:The applied body of spraying is provided with oscillation after applying the spraying work of monolithic refractory or while applying the same. Gas, such as air and the like which is contained in the applied body obtained by spraying, is deaerated by providing the applied body with oscillation in such a manner whereby the tight applied body can be obtained. On the other hand, the viscosity of the applied body is deteriorated by oscillating it and fluidizing is generated in the applied body whereby the ununiformity of organization or so-called lamination can be eliminated. When this method is applied on a horizontal site, the rebound and the like of the applied refractory material are not necessary to be considered and, further, the provision of viscosity increasing effect, which is effected conventionally with respect to usual dry type spray material and the like in order to improve the adhering rate of the same, is not necessitated whereby applying body, containing low moisture, becomes easy to be obtained.

Title: Prediction coder
Inventor: ARAI MITSUTOSHI
IPC: H04N19/593
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To obtain a high compression rate by allowing a predict section to have plural prediction object picture elements and to predict them in the lump in the unit of plural picture elements to reduce the signal quantity for prediction signals and a code quantity. SOLUTION: A prediction device 2 predicts a pattern of plural prediction object picture elements from a pattern of input image data effecting on plural reference picture elements to provide an output of a prediction signal (a). A comparator 3 compares the received prediction signal (a) with image data received from an image input terminal 1 to discriminate whether or not the both are coincident. When the both are coincident (prediction is hit), a level '0' is outputted as a prediction error signal (b). When the both are not coincident, the comparator 3 provides an output of information denoting which picture element prediction is not hit among the prediction object picture elements as the prediction error signal (b). This information is made up of plural bits whose most significant bit is '1'.  A coding section 5 generates a run length code depending on the run length of the prediction error signal.

Title: Super abrasive grain wheel
Inventor: TAKEUCHI KEIZO
IPC: B24D5/00
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To provide a super abrasive grain wheel excellent in joining strength by setting the Co content of cemented carbide to specific %. SOLUTION: A super abrasive grain layer is fixed to an outer periphery of base metal, and cemented carbide composed of alloy of WC and Co is used as a base metal material. In the case of joining by an adhesive and joining by sintering, when the Co content is less than 10%, manufacture itself cannot be performed by joining failure, and even in the case of electrodeposition, manufacture can be only partially performed when the Co content is 8%. When the Co content exceeds 10%, 5kg/mm<2> being a standard for practical joining strength can be secured. Particularly, in the case of a metal bond, a sudden increase in joining strength with 10% as a boundary is confirmed. A similar effect is also confirmed on a WC-TiC-Co type and WC-TiC-TaC-Co type. Therefore, when the Co content is set to 10 to 25%, sufficient joining strength can be provided by a conventional joining method, and the base metal itself can be formed in high tenacity and high strength.
