Title: Direct-current transmission system
Inventor: UEDA KAZUMI
IPC: H04L7/04
Filed: 1980-04-21
Abstract: PURPOSE:To prevent the erroneous actuation of a start-stop synchronous receiver by preventing a noise from being regarded as a start signal by sending a synchronizing signal, differing in polarity from firm data, for a certain time or longer before the start signal is transmitted from a transmission side and by monitoring the time of the synchronizing signal at the reception side. CONSTITUTION:Firm data ND1 and ND2 in the transmission format of data transmitted from a transmission side are made different in polarity from start bits ST1 and STS and between data ND1 and start bit ST1, synchronizing signal SYN having the opposite polarity is interposed. The synchronizing signal of positive voltage +V from the transmission side is monitored by time monitoring circuit 1 at a reception side, and start bit detecting circuit 2 is driven by negative voltage -V arriving certain time T later as start bit ST1 to apply start-stop synchronizing start signal D to data gate 3, transmitting data Sin to the rear stage. Then, the malfunction of a receiver is prevented by preventing noise X1 generated in data ND1 or noise X2 in synchronizing signal SYN from being regarded as the start signal.

Title: Area specifying device for copying machine
Inventor: MAEYAMA KAZUO
IPC: G03G15/36
Filed: 1986-03-08
Abstract: PURPOSE:To easily grasp an area to be specified and to eliminate simple errors such as the coordinate input of a wrong position by displaying the positions of end parts corresponding to four segments when the end parts of a copy area or erasure area are specified. CONSTITUTION:Four segments (c), (d), (e), and (g) of the 8-shaped segments of the 3rd digit are lighted after a power source is turned on, a RAM is initialized, and a range setting mode key is operated. Then, those segments blink to indicate a state in which the right and left ends of the area need to be inputted. When, for example, 11 is inputted with ten keys, the registered number is displayed. The number on the display is cleared with an input key and inputted to a buffer. Then, a counter is incremented and the segment (e) lights to indicate a state in which a number is put in the buffer. Similarly, the coordinates of the right and left, and front and rear ends are grasped visually and inputted easily over a look at the display of the four segments (c)-(g).

Title: Alignment mark position detection
Inventor: FUJINAGA MASATO
IPC: H01L21/67
Filed: 1986-03-10
Abstract: PURPOSE:To facilitate highly accurate detection of an alignment mark by a method wherein the alignment mark and a foundation are scanned by a focused ion beam and a radiation beam is created from the alignment mark or from the foundation or different radiation beams are created from both the alignment mark and the foundation. CONSTITUTION:An alignment mark 2 and a foundation 1 are scanned by a focused ion beam (FIB) 4 which is set to have a predetermined energy applied through resist 3. In the above description, a predetermined energy means the energy which is high enough to produce a radioactive substance at a collision point 7a and not high enough to produce a radioactive substance at a collision point 7b by utilizing the fact that the film thickness of the resist 3 on the alignment mark 2 is smaller than the film thickness of the resist 3 on the foundation 1 and the energy of the FIB 4 is reduced while it is passing through the resist 3. The radiation emitted from the produced radioactive substance is detected. The alignment mark and the foundation may be made of different materials. With this constitution, the alignment mark position can be detected with high accuracy by detecting the radiation with high sensitivity.

Title: Data transmission method between a plurality of inverters
Inventor: MIZUBUCHI HIROOKI
IPC: H02J3/38
Filed: 1991-03-18
Abstract: PURPOSE:To obviate the necessity of dedicated interface by serving an I/O control terminal for normal signal as an I/O interface for serial data when a plurality of inverters are operated while being interconnected through a serial communication circuit. CONSTITUTION:Data communication is carried out between a master unit, i.e., the first inverter 1-1 out of N inverters connected through a transmission line 3, and slave units, remaining N-1 inverters. Four terminals in a control terminal i.e., block 2-1 are employed as the serial data I/O interface with an external control circuit in the communication of 1 bit data and 4 bit binary data due to modification of terminal function. For example, command input data such as operation/stop commands(HLD, FWD, REV), multi-stage speed switching commands (X1, X2, X3) are transmitted individually or simultaneously to the N inverters. Consequently, a communication data I/O interface dedicated for each inverter is not required.

Abstract: PURPOSE:To prevent electronic members on a printed board from being damaged due to excess current by allowing the opposite side polarity of each serial resonator to coincide with that of its adjacent parallel resonator. CONSTITUTION:The connecting projections 11 of terminal plates connected to front and rear end parts of respective serial resonators 5 constituting a filter circuit F are connected to the I/O terminals 20, 21 of the printed substrate and the connecting projections 12 of the intermediate terminal plates of respective parallel resonators 7 are connected to ground terminals 22.
