Title: Disk chuck mechanism
Inventor: NAKADAI TSUTOMU
IPC: G11B23/00
Filed: 1987-08-18
Abstract: PURPOSE:To chuck and revolve a disk substrate, etc., without damaging it by supporting a clamp, which goes to be one side of a chuck piece, by an axis to pass through the hub of a spindle with facing to the hub. CONSTITUTION:A clamp 12, which goes to be one side of the chuck piece, is supported with facing to a hub 11 of a spindle 10 and the plural numbers of turning arms 15 are provided to revolve on a surface rectangular to the surface of a disk 3 to be chucked. Further, a spring is provided to turn these respective turning arms 15 so as to be closed toward the hub side in the direction of a central line to connect the centers of the spindle 10 and the clamp 12. In such a case, since the clamp 12 and the hub 11 are positioned on the same axis, eccentricity is hardly generated between them. Thus, the chuck can be positioned in one direction side and the disk can be chucked without fail. Then, there is no dislocation in the revolving center of the chuck piece and even when the disk is revolved, the chuck surface is hardly damaged.

Filed: 1988-08-18
Abstract: PURPOSE:To improve a breakdown voltage between a transistor and a substrate by diffusing a buried layer under a collector layer having one conductivity type diffused in an isolating region in lower impurity concentration and higher depth than those of a buried layer under a bipolar transistor having the isolating region as a collector layer. CONSTITUTION:When a higher voltage than a power source voltage is applied to a collector layer 7 through the collector terminal C of a P-N-P transistor Tn due to a certain cause, this high voltage is transmitted to a buried layer 2 forwardly through a junction between the layers 7 and 2. Accordingly, the breakdown voltage value of this vertical P-N-P transistor Tp is determined by the breakdown strength value of a junction between the layer 2 and a substrate 1, the impurity concentration of the layer 2 is low, a depleted layer tends to extend to the junction, its diffusion is deep, and an electric field concentration to the corner of the junction is small. Accordingly, the breakdown strength voltage value is improved several times as large as a conventional one to easily obtain the value of 50V or more.

Abstract: PURPOSE:To reduce the number of externally mounted capacitors and externally mounted pins in the formation of IC by applying constant current charge/ discharge of a capacitor in response to the collector current of the 1st and 2nd TRs connected differentially so as to generate a triangle wave output signal at a capacitor. CONSTITUTION:A capacitor 18 is connected to a base of the 2nd TR 17 in the 1st and 2nd TRs 16, 18 connected differentially. In applying a power supply +Vcc and the initial charge of the capacitor 18 is assumed as zero since the base voltage of the TR 17 is zero, the TR 16 is turned on and the TR 17 is turned off just after the application of power. Then TRs 23, 24, 25 are turned on, the capacitor 18 is charged by the collector current of the TR 25. When the constant current charging of the capacitor 18 is propressed and its terminal voltage reaches the base voltage of the TR 16, the TRs 17, 26 start the turning on and TRs 27, 31, 29 and 30 are turned on. Thus, the electric charge in the capacitor 18 is discharged through a constant current through the collector- emitter path of the TR 30.
