Title: Keyless type shaft coupling having engagement groove for fixing shaft
Inventor: NAKANO TAMIO
IPC: G05G5/06
Filed: 1982-05-25
Abstract: PURPOSE:To reduce the surface stress on an outside cylinder and reduce the outside diameter of said outside cylinder by reducing the edge surface effect by removing an engagement groove for shaft fixation in the range where the edge surface effect is generated. CONSTITUTION:On an outside cylinder 7, an engagement groove 6 is not formed in the range where the edge surface effect is not generated, namely in the part of length corresponding to 5-50% of the diameter d of a driving shaft 1 and a driven shaft 2, over the range from the both edges of the outside cylinder 7 to the center part, and the engagement groove 6 is formed only in the center part 7a. Therefore, the surface stress on the outside cylinder 7 can be reduced, and the outside diameter of the outside cylinder 7 can be reduced by that degree. Stress concentration can be relieved by forming the corner part 6a of the engagement groove 6 to a curved surface, and the outside diameter of the outside cylinder 7 can be reduced by preventing the stress concentration and the edge surface effect from acting synergistically onto the outside cylinder 7.

Title: Scanning speed modulating circuit
Inventor: ISHII YOSHINORI
IPC: H04N3/32
Filed: 1993-04-16
Abstract: PURPOSE:To display the rising and falling transient parts as the sharp edges by supplying selectively the primary differential signal acquired by applying the primary differentiation to a video signal and the signal acquired by delaying the primary differential signal to a modulating coil. CONSTITUTION:A video signal is supplied to a primary differentiating circuit 14 and a primary differential signal is acquired. A delay signal is acquired through a delay line 15 which delays the primary differential signal. These differential and delay signals are supplied to the sides (a) and (b) of an SW 16 respectively. The undelayed primary differential signal is supplied to a controller 17. Then the controller 17 integrates the primary differential signal to switch the SW 16 to the side (a) only when the level of integration output is equal to the positive output (excluding 0) and otherwise switches the SW 16 to the side (b). Then integrated differential signal is amplified by an amplifier 18, and a current is supplied to a speed modulating coil 11 through a drive circuit 19. Thus it is possible to delay the scanning speed in the periods of both rising and falling transient parts of the video signal.

Title: Alignment method, formation of alignment mark, and aligner and method for exposure
Inventor: NAKAJIMA SHINICHI

Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To improve the throughput, when the position alignment is performed by using the alignment marks, which are formed at respectively different layers in the X-direction and the Y-direction. SOLUTION: An X-direction alignment mark 40a and a Y-direction alignment mark 41a are formed in close proximity, so as to enter the same image-pickup region at the different layers on a substrate. The X-direction measurement and the Y-direction measurement are performed at the same time. Thus even when the position alignment is performed by the use of the alignment marks, which are formed on the different layers in the X-direction and the Y-direction, simultaneous X and Y measurements can be made, and improvement in the throughput can be realized.

Filed: 1985-04-26
Abstract: PURPOSE:To test the generation of a voice signal independently in the unit side by operating a voice signal generating means with not only a voice output instruction taken in from a system bus but also a simulated voice output instruction given independently of said voice output instruction by internal manual operation. CONSTITUTION:A voice synthesizing part 510 synthesizes the voice signal of a minute time in accordance with one-byte components of data outputted from a voice data ROM 508 and sends back an interrupt signal to an MPU 501 each time when synthesis is terminated. Then, the MPU 501 executes the voice generation continuing processing in response to the interrupt signal. The voice signal of the synthesizing part 510 is inputted to an amplifier 513 for monitor through an LPF 511, and one branched output is connected to a changeover switch 514. Thus, a test switch (DIP switch 54) is operated to generate the simulated voice output instruction and the switch 514 is switched to the side of the amplifier 513, thereby connection directly a speaker for monitor to a jack 53 to perform the voice test.

Abstract: PROBLEM TO BE SOLVED: To prevent a followup error from being affected during acceleration/ deceleration and to compensate backlash at the time of stop by fitting a 2nd servo motor for driving a load shaft and a 3rd pulse generator for detecting the rotating angle of the load shaft with the passage of time. SOLUTION: A pulse generated by a 3rd pulse generator 30 installed on the load shaft is read by a counter 35, and a rotating angle θ34 of the load shaft is calculated by a load shaft rotating angle calculation circuit 33.

Title: Access control system to external memory
Inventor: SUZUKI TOMOAKI
IPC: G06F12/00
Filed: 1984-05-07
Abstract: PURPOSE:To prevent the double generation of the record of the same key as well as the destruction of said record by keeping access waiting until the access is through with an access data file area and permitting an access when the area to receive an access is different from the area which is kept under access. CONSTITUTION:When a data controller 31 gives the access control to a data file area 13, the access right is acquired to an external memory 1 with inhibition given to the accesses of other data controllers 32-3n. Then the controller 31 checks all of (n) switch areas in a control area 2 corresponding to the area 13. As a result, it is decided that no controller which is giving access to the area 13 exists as long as no switch flag is set. Then a switch flag corresponding to the self-controller 31 is set at 1, and the inhibition of access is released for controllers 32-3n. Therefore the access control is possible with controllers 32-3n as long as the file areas are different.
