Title: Touch sensitive device for electronic musical instrument
Inventor: ASAHI YASUHIKO
IPC: G10H1/34
Filed: 1990-10-09
Abstract: PURPOSE:To perform delicate touch-response control displaying the intention of a player with fidelity and to perform performance with full of variety and full of expression by controlling a musical tone considering not only the time difference of contact but the degree of change of a timing pulse during that time. CONSTITUTION:The data of the time difference of contact is corrected by finding the change rate of two points between time intervals from the on-time of a first make switch to that of a second make switch in key depression by a touch-response switch 30 provided at every key based on not only the time difference of contact in the above time intervals but the output of a stroke sensor 20 which senses the time intervals in microscopic fashion, and adding the change rate. As a result, the output of different touch sensitivity based on the travel history of a key depending on the way of key depression can be obtained even when the time difference of contact is same. Therefore, it is possible to perform the performance with fidelity to the intention of the player and with full of expression by controlling the musical tone by the output of the touch sensitivity.

Title: Throttle valve control device for internal combustion engine
Inventor: TEZUKA KAZUNARI
IPC: B60W10/10
Filed: 1987-10-27
Abstract: PURPOSE:To make it possible to smoothly return a throttle valve into an inherent throttle control condition after avoidance of a risk of slip, by providing a desired throttle opening degree returning means for gradually changing the output value of a desired throttle opening degree compensating means after determination of occurrence of a slip, to a value before compensation during a time lapse.

A compensating means 31 compensates and limits a desired throttle opening degree value thetad1 which is set by a desired opening degree setting means 28, in accordance with the output value muL from the setting means 30 in order to avoid slip on a low friction road so as to attain a safe running. After avoidance of this slip, a desired throttle opening degree returning means 32 gradually changing the output value of the desired throttle opening degree compensating means 31 to a value before compensation so as to return the output value to the desired throttle opening degree thetad1 demanded by the driver. As a result, it is possible to smoothly return the throttle valve into an inherent throttle control condition, thereby it is possible to recover the manipulatability.

Title: Method for adding active metal to molten copper
Inventor: KATAGIRI NOZOMI
IPC: B22D11/10
Filed: 1990-10-08
Abstract: PURPOSE:To improve the uniform mixing property of an active metal by adding the active metal to the descending flow of molten copper in the upper part of a continuous casting mold. CONSTITUTION:While the molten copper 2 is tapped from a melting furnace 1 to a runner 3 a pure Mg rod 7 is fed from the inside of a stopper 4 positioned on the extreme downstream of the runner 3, i.e., the stopper 4 of a molten copper inflow hole 6 to the continuous casting mold 5 to add the Mg to the molten copper. The Mg of the active metal is eventually added to the descending flow 8 of the molten copper in the upper part of the continuous casting mold 5 in this way. The added Mg rides on the descending flow 8 of the molten copper and flows down together with the molten copper in a nozzle 10 while melting in the molten copper and flows into the continuous casting mold 5 where the Mg solidifies as the Mg-contg. copper alloy. A slab 9 is thus formed.

Abstract: PROBLEM TO BE SOLVED: To prevent the short circuit between solders, by equipping a terminal mounting structure with a circuit board where a plurality of through holes are made, a comb-toothed retaining member where a plurality of terminals are extended in one direction, and solder for attaching the plurality of terminals to the circuit board, and attaching the terminals, with spacing between the topside of the solder and the retaining member. SOLUTION: A plurality of terminals 1 are inserted in one direction and are extended and held in the shape of comb teeth in the retaining part 12 of heat-resistant resin, thus they are united at specified pitches by insert molding or the like. Moreover, the topside 12a and the bottom face 12b are made at the retaining member 12, and in the direction of extension of the terminal 1, projections 12c are made downward with a height dimension C from the bottom face 12b at both ends of the retaining member 12. The fused solder 4 flows to the conductor part 13 within a through hole 13a, and the solder 4 swelling conically is pulled in the through hole 13a, so the height of the cone becomes a little low. Accordingly, the dimension A between the adjacent solders 4 hardly changes before and after the soldering, and the solders do not contact with each other, and they are never shot-circuited.

Title: Correcting method for coordinate information, dictionary registration method and character recognition device
Inventor: FURUICHI YOSHIO
IPC: G06F3/0488
Filed: 1994-11-07
Abstract: PURPOSE: To improve a character recognition rate by performing character recognition after the deformation of a character inputted by handwriting when it is inputted is corrected. CONSTITUTION: The coordinate information of a handwritten character inputted from a coordinate input device 6 is inputted to a coordinate data buffer 41 by an input part 32. A neighborhood degree calculation part 33 calculates a degree of boundary neighborhood for the frame boundary of an input frame at each input point shown by the coordinate information, and stores it in a boundary neighborhood data buffer 43. Thence, a data correction part 34 corrects each input point by using the degree of boundary neighborhood, and stores obtained coordinate information after correction by overwriting on the coordinate data buffer 41. A character recognition part 35 performs character recognition by referring to a character recognition dictionary 51 after converting coordinate data after correction to a relative coordinate value.  In this way, the coordinate information after correction goes to data in which the deformation of the character inputted by handwriting is corrected, which improves the character recognition rate.

Inventor: YAMADA MASANORI
IPC: G03G21/00
Filed: 1986-11-17
Abstract: PURPOSE:To improve operability by selecting simultaneously a function by a setting means which sets automatically variable magnification from a desired read area to a recording medium of desired size and a function by a supply control means which selects a recording medium of an optimum size in relation to the size of a formed image. CONSTITUTION:Magnification when detected original size and specified original size are varied automatically to form size data on forms set at paper feed stages is calculated and forms are so selected that the magnification approximates 100%. Then when both functions of automatic variable magnification and automatic form selection are selected simultaneously with soft keys SK4 and SK5, magnification for which the automatic variable magnification is specified is set automatically to 100%. When the automatic variable magnification function is selected while the automatic form selecting function is already selected, or vice versa, the function which is already set is never switched contrary to the intention of an operator by giving priority to the function which is selected later. Consequently, there is no restriction of use and the operability is high.
