Filed: 1988-11-17
Abstract: PURPOSE:To decrease the wrong key input operations by enabling an operator to set the position of a pointing device like a finger, etc., approximately at the center of a desired key based on an image of a magnified keyboard shape. CONSTITUTION:When a touch-on state is obtained while a keyboard-shaped image is displayed on a display device 4, a touch panel control part 6 informs a control part 9 of the touched-on coordinates. The part 9 gives the magnification control data centering on the informed coordinates to a screen magnification control part 8 for display of a magnified screen. Thus an operator can set a pointing device like a finger, etc., approximately at the center of a desired key. Then the operator changes the touch position approximately at the center of a desired key based on the keyboard-shaped image displayed with magnification and then performs a touch-off operation. Thus the part 6 informs the part 9 of the relevant coordinates. The part 9 decides an input key based on the coordinates and inputs the decided key.

IPC: G11B5/842
Filed: 1989-11-10
Abstract: PURPOSE:To drastically improve dispersibility of emulsion in coating material by a method wherein W/O emulsion is formed by adding a king of salt selected from Co, Zn, Ti Sn and Zr to a ferric salt and barium salt aqueous solution and also by adding an organic medium, which is insoluble in a surface activating agent and water, to the above-mentioned material, and the mixture is precipitated by adding alkali. CONSTITUTION:Ferric salt and barium salt are dissolved into water, and a kind of salt selected from Co, Zn, Ti, Sn and Zr is added to an aqueous solution. It is necessary that the salt of the above-mentioned elements must be formed into the salt having the anion same as the ferrite salt and the barium salt. The organic solvent, which does not mix together with water to be added to a metal salt aqueous solution, is the organic solvent which is separated into two layers when it is made to stand after it has been mixed and shaked. As the surface activating agent to be added to the metal salt aqueous solution, the nonionic material such as sorbitan monooleate and the like having the HLB value of 4 to 6, which is suited for W/O emulsion, is considered suitable. Using a powerful dispersing machine, the emersion particles of the metal salt aqueous solution formed in the organic solvent, which is insoluble in water, are mixed with an alkali aqueous solution, and metal hydroxide is precipitated. When the starting raw material is a chloride, pH adjustment is conducted using hydrochloric acid.

Filed: 1988-11-18
Abstract: PURPOSE:To make possible the detection in high probability by receiving first and second wave motions whose phases are reverse each other in time series every a specified cycle from a transmitting wave portion and reversing the phase of a received signal to output as an existing received signal. CONSTITUTION:After two signals which are made reverse phases each other are converted into supersonic waves, alternately transmitted in time series and the supersonic waves reflected by a measuring object 20 are received in time series, one cycle is delayed in one signal to perform difference composition with succeeding signals so that correlative high obstructions can be offset or controlled every pulse repeating cycle.
