Title: Magnetic head supporting body
Inventor: HASHIMOTO MASANOBU
IPC: G11B21/21
Filed: 1988-06-22
Abstract: PURPOSE:To prevent the contact sliding and adsorption of a slider and a disk by providing a piezoelectric element, a wadding material and a holding spring to arrive through an insulating material at the central part of a suspension spring at the negative pressure slider existing side of a suspension spring rear edge part. CONSTITUTION:When a voltage is impressed to a piezoelectric element 5 after a spindle starts the rotation and a disk arrives at a stationary speed, the dis placement occurs in the direction in which the tip is separated from a suspension spring 3, and when the spring 3 deflected beforehand approaches to the flat condition, a negative pressure slider 1 joined through a jimbal spring 2 to the tip approaches the surface of a disk 7. When the surface of the disk 7 and the lubricating surface of the negative pressure slider 1 arrive at approximately several tens of micron, a self-loading action occurs at the negative pressure slider 1 and the negative pressure slider 1 is smoothly loaded on the disk 7. Further, when the piezoelectric element 5 is deflected, a wadding material 6, a pad 10 and the spring 3 are completely away, and the piezoelectric element 5, the pad 10 and a holding spring 9 do not give any adverse influence to the suspension spring 3.

Title: Radio selective calling receiver
Inventor: OTA MAKOTO
IPC: G04R20/00
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To facilitate recognizing a world time by grouping areas conventionally used by a user as home areas and areas for moving destinations as sub areas having a time difference between both the areas and separately displaying them. SOLUTION: In the case that base identification information included in received information frequency information in a home area matches with personal information in an ID-ROM, the receiver is locked in synchronization. In the case of receiving time data, the time data are stored in a 1st area table of a clock section 3, based on the base identification information received simultaneously and counted, and a clock for a home area on a display section 4 is corrected and a home area clock is displayed. When the receiver moves to a sub area, the synchronization is unlocked. When the receiver is locked in a 2nd area of the home area again and receives the time data, the data are stored and counted in a 2nd area table of the clock section 3 according to the base identification information.  Thus, the clock display on the display section 4 is corrected by the time indicated by the sub area, and the corrected time is displayed.

Filed: 1985-07-15
Abstract: PURPOSE:To accurately detect the surface potential of an object to be measured regardless of the change in the DC ions surface potential of said object, by supplying the power of an independent power source circuit to an impedance converter circuit separated from a signal processing circuit according to a DC system. CONSTITUTION:Output due to a detection electrode 10 is subjected to impedance conversion by a circuit 21 containing FET 31 and inputted to a signal processing circuit while a DC component is cut by a capacitor C1. At this time, an external variable voltage generating means 24 is used in common to one applying DC bias voltage to the surface of a measuring object and reference voltage having the same potential as the DC bias voltage applied to the surface of the object to be measured is applied to the electrode 10 and, therefore, the source output of FET 31 applies the output corresponding to the surface potential of the object to be measured to the signal processing circuit.

Title: Absolute value detecting signal processing circuit device
Inventor: FURUKAWA TATSUO
IPC: G06G7/25
Filed: 1991-06-27
Abstract: PURPOSE:To secure a dynamic range for a absolute value detecting signal processing circuit where the emitters of transistors are connected in common to each other by giving the input offset to the precedent stage of an absolute value detecting circuit through a compensating circuit to cancel the operating point shift and to eliminate the fluctuation of the operating point. CONSTITUTION:The DC component of an input signal is cut by a capacitor 3. The inverse amplifiers 1 and 2 apply previously the input offset voltage VBE(8) with a PNP transistor(TR) 8 of an input stage and set the output voltage level at a voltage level secured by adding the voltage VBE(8) to the reference voltage VR. In an absolute value detecting circuit 4, the potential is reduced at a point A by the base-emitter voltage VBE(7) of an npn TR 7. Meanwhile the potential is reduced at a point B by the base-emitter voltage VBE(6) of an npn TR 6. Then the voltage VBE(8) is set at the levels equal to the VBE(6) and VBE(7) and these voltage levels are canceled. Thus the output voltage levels are set at the levels approximately equal to the VR.
