Filed: 1987-11-27
Abstract: PURPOSE:To shorten a time and to set the capacity of a memory circuit to the necessary min. value, by generating not only the first address signal every step of scanning but also the second address signal corresponding to the bio- signal from an object to be examined and writing the data obtained from an X-ray detector at every step of scanning in the address indicated by each of the first and second address signals. CONSTITUTION:The angle of rotation of a disc 2 is detected by a rotation detector 6 and the angle signal thereof is sent to an address generating circuit 9 through an interface circuit 7. This address generating circuit 9 generates the address signal (x) corresponding to the inputted angle signal and the bio- signal of an object to be examined is amplified by a bio-signal amplifier 10. Said bio-signal is sent to a timer circuit 11 and the phase signal corresponding to the time from the predetermined phase of the bio-signal is formed and sent to an address generating circuit 12 to generate the address signal (Y) corresponding to the phase of the bio-signal. The X-ray transmission data sent to a memory 8 through the interface circuit 7 is written in the address indicated by both address signals X, Y.

Title: Susceptor for semiconductor process and its manufacture
Inventor: MIKAMI KAZUHIKO
IPC: H01L21/205
Filed: 1993-11-30
Abstract: PURPOSE:To improve precision and surface flatness, and increase the chucking force of a silicon wafer, by a method wherein, after a flat substrate is thickly coated with an aluminum nitride film, a trench is formed by working the aluminum nitride film itself. CONSTITUTION:The substrate 2 surface on which an aluminum nitride film is formed is previously flattened by polishing, grinding and chemical treatment, and an aluminum film 3 is formed. Specified trenches 4 are formed by grinding the aluminum nitride film 3. Since the trenches 4 are formed in the aluminum nitride film 3 itself, the working precision of the trench is high, and the surface flatness is excellent. Thereby the chucking force of a silicon wafer is large, and high quality can be realized at a low cost. Further, since the surface which mounts a wafer and is exposed in a semiconductor manufacturing equipment is constituted of the aluminum nitride film 3, plasma resistance is obtained and the life of a susceptor is improved.

Title: Control circuit for magnetic bearing
Inventor: TAKAHASHI NAOHIKO
IPC: F16C32/04
Filed: 1991-11-18
Abstract: PURPOSE:To enhance rigidity and a damping characteristic of a bearing by connecting a proportional circuit between a sensor circuit and a compensating circuit or between a compensating circuit and current amplifiers, and returning a signal output from the proportional circuit in a positive or a negative output to an input of the proportional circuit through a low pass filter secondary or further. CONSTITUTION:A displacement sensor 2 detects a displacement in the circumferential direction of a rotor as a voltage signal in forming a pair with a sensor converter 4. The obtained displacement signal is compared with a target value signal, to be input into a compensating circuit 5 as a target deviation signal (e). The compensating circuit 5 compensates stable lifting of the rotor. A signal obtained by returning an output from the compensating circuit 5 and an output from a proportional circuit 8 through a secondary low pass filter 9 is additionally input into the proportional circuit 8. Power amplifiers 7a, 7b control a current supplied to a magnetic bearing on the basis of the output from the proportional circuit 8, divided into a positive and a negative output by a switcher. Consequently, a gain is increased at a frequency not higher than a cut-off frequency of the filter 9 so that a high frequency gain can be relatively restrained, thus enhancing rigidity and a damping characteristic of the bearing.
