Title: Method for electron beam lithography
Inventor: GOTOU HIDEKAZU
IPC: H01J37/317
Filed: 1979-08-24
Abstract: PURPOSE:To perform highly accurate describing images by keeping the cross- sectional area of an electron beam approximately constant, and varying the shape of the cross section. CONSTITUTION:The cross sectional area of an electron beam can be formed by masks M1 and M2, a lens 3 between both masks, and a pair of deflectors 5. The cross-sectional area is kept approximately equal, but the shape is sequentially varied as q1, q3, and q4 by the control of an electronic computer 4, and a pattern is described. The excitation of a projecting lens 6 is controlled 4 so that the image is focussed on a specimen 7 at the current value of the electron beam having a cross- sectional area S. In the case a pattern q9 which is slightly smaller than the area S or a pattern q10 which is slightly larger is described, the description is performed with the excitation of the lens 6 being constant and with only the cross section of the electron beam varied, since the blur of the current of the electron beam is in the allowable limit. In this constitution, resultant highly accurate describing can be performed by the electron beam having no blur.

Title: Tracking signal detecting circuit for optical reproducing device
Inventor: TAKAHASHI SUSUMU
IPC: G11B7/09
Filed: 1985-05-21
Abstract: PURPOSE:To obtain a signal detecting circuit by a wobbling method by which a correct tracking signal is obtained, by providing a means for eliminating a component caused by a variation of a bit length, from an amplitude of an FM wave, by a demodulating signal obtained by a frequency discrimination of the FM wave. CONSTITUTION:An optical beam transmitted through a disk 1 is detected by a photodetector 4. A turning mirror 2 is vibrated by a wobbling signal from an oscillator 9. Accordingly, an output of the photodetector 4 is an FM wave of an amplitude which is varied by a bit length variation and the wobbling signal. This FM wave is brought to a frequency discrimination by a frequency discriminator 6 through an FM modulator 5, and a demodulating signal is obtained frmo an output terminal 10. This demodulating signal is applied to the amplitude modulator 5 and the amplitude of the FM wave is brought to a reverse modulation. In this case, by setting suitably a level of the demodulating signal applied to the amplitude modulator 5, a bit length variation portion can be eliminated from an amplitude variation of the FM wave.

Title: Data transmission system
Inventor: YAMADA ISAO
IPC: H04L12/00
Filed: 1985-05-21
Abstract: PURPOSE:To attain high-speed data transmission by providing a fixed time slot and a variable time slot in a loop network communication system of the TDM system. CONSTITUTION:A supervisory control station 10 gives a frame as shown in a figure to a transmission line. The first half of the frame is the same as that of the TDM system and the latter half is that of the token system. Then a control section 23 extracts selectively a frame header FH, a free token FT or a busy token BT from a signal sent via a transmission line and discriminates a time slot. When a node (n) desires high-speed data transfer, the control section 23 of the node (n) acquires the free token FT at the head of the latter half. When the control section 23 of the node (n) catches the free token FT, the free token FT is changed into a busy token BT and then data is sent. In this state, other nodes cannot use it. When the data transfer by the node (n) is finished, the control section 23 of the node (n) changes the busy token BT to the free token FT again and restores the state that an optional node is used.
