Title: Synchronism detector
Inventor: SUZUKI TOSHITATSU
IPC: G03G15/04
Filed: 1980-06-10
Abstract: PURPOSE:To generate the synchronizing signal which controls the position for starting writing of images highly accurately with simple constitution by deflecting and detecting at least one of the scanning beams passing through a microspacing and generating the synchronizing signal according to processing in a laser printer or the like. CONSTITUTION:The scanning light of a laser or the like modulated according to the images forming latent images on a photosensitive drum 9 or the like is reflected by a half mirror 24 in a position P1 and is detected with a photodetector 17. In a position P2, it transmits through a mirror 24 and is detected wit a photodetector 18. Hence, the scanning beams spaced by a microspacing are detected respectively by two sets of the elements 17, 18 disposed in desired positions and the complication of the constitution is prevented. If one of these detection outputs is inverted and is added to the other detection output, the synchronizing signal controlling the position for starting writing of images highly accurate is generated by way of a zero detecting circuit 21.

Title: Multiplex transmission equipment
Inventor: YONEKURA YASUTO
Filed: 1985-04-12
Abstract: PURPOSE:To continue the signal transmission even when a trouble happened to the line connection a primary station and plural number of a secondary station in loop, by changing the primary station to loop back mode and turning back the signal from the adjacent station to the trouble. CONSTITUTION:Plural number of secondary stations 2-5 are connected in loop to a primary station 1 by two-core transmission cable 6. The primary station 1 outputs poling signal, start signal and data signal from its output terminal 1-0. The secondary station takes in the poling signal and when own station is specified, receives the data by the start signal from the higher rank station and sends out data of own station to lower station. When own station is not specified, it delivers the data to the lower station. When no start signal nor data signal is received at input terminal 1-i, the primary station 1 is changed to loop back mode, and sends out signals from both input and output terminals, and receives by both terminals the signal returned back from the adjacent station to the trouble. In this way, the multiples transmission can be continued even when there occurs a trouble.

Abstract: PURPOSE:To obtain good quality internal characteristic and to improve working environment without developing any noise by setting plural magnets keeping some interval in peripheral direction of a rotary flask and also arranging a coil for floating up at lower part of the rotary flask and means for rotation- driving the rotary flask. CONSTITUTION:At the time of rotation-driving the rotary flask 1 with the rotation-driving means, as the rotating velocity becomes faster, more induction current is conducted into the coil 4 for floating up by changing the magnetic flux with the magnet. By this method, the rotary flask is floated up by repulsion between the generated magnetic force and the magnet, and this rotary flask is made to rotate under floating up condition. Therefore, the development of vibration is restrained, and adverse effect is not given to the product and the working environment is improved without developing any noise. Further, by constituting the magnet by conducting the electric current into superconducting coil, the large magnetic force can be obtd. with a small size construction. Further, by rotation-driving the rotary flask by forming rotating magnetic field around the rotary flask, as the rotation-driving is executed under non-contacting condition, the vibration and the noise can be further restrained.
