Title: Optical information recorder
Inventor: SUNAKAWA RYUICHI
IPC: G11B7/0045
Filed: 1991-11-15
Abstract: PURPOSE:To provide the optical information recorder capable of correcting the laser light intensity according to the pit formation state at the time of recording information. CONSTITUTION:The recording of the information is performed by changing the laser light intensity corresponding to a reference digital signal A from a laser driving circuit 28. The reflection light from the optical disk 1 during recording is received by a photodetector 212, and a signal B with the voltage proportional to the light intensity is outputted. The voltage of a signal B' amplifying the signal B by a pulse signal C corresponding to the trailing part of the pit part and a pulse signal D corresponding to the center part of a non-pit part in an RF amplifier 22 to be generated from a timing pulse generation circuit 23 based on the reference digital signal is held in sample-and-hold circuits 24 and 25. The energizing current to a laser diode 211 is controlled to match the voltage difference and the reference value at all times. Thus, the pit shape corresponding to the reference digital signal can be formed.

Abstract: PURPOSE:To obtain a brushless motor with less rotation irregularity, by a method wherein gear-shaped teeth are formed on the outer periphery of a rotor yoke and magnets, fixed so as to correspond to the teeth, are provided on the outer periphery of the teeth. CONSTITUTION:Gear-shaped teeth 15 are provided along the whole outer periphery of a rotor yoke 14. Three pieces of the teeth are provided with respect to one pole of a multi-pole magnet, provided on the side of a rotor. Accordingly, the number of teeth is 24 and a pitch angle is 15 deg. when the number of pole is eight. Magnets 16 are fixed at positions opposing to the teeth 15 of the toothed rotor yoke 14. Upon the provision of the magnets 16, the position of the magnets 16 is set so that a loss torque, corresponding to a torque ripple generated in a motor, is generated. In a motor, constituted in such a manner, the flux changes into waveform between a position, whereat the teeth 15 are opposed to the fixed magnets 16, and another position, whereat the groove or the trough 17 between the teeth 15 is opposed to the fixed magnet 16, whereby torque ripple may be restrained.

Title: Automatic data communication system
Inventor: KIKUMOTO YOSHIBUMI
IPC: H04J3/06
Filed: 1988-11-29
Abstract: PURPOSE:To evade malfunction by using a synchronizing signal when the synchronizing signal is generated from a communication line terminator and using a synchronizing signal generated in a terminal equipment automatically when no synchronizing signal is generated so as to send a transmission data from the terminal equipment. CONSTITUTION:When a synchronizing signal is generated from a communication line terminator 1, the synchronizing signal is sent to a terminal equipment 3 via a signal line 21, inputted to a synchronizing signal detection circuit 31 and also a synchronizing signal switching circuit 32. When a signal outputting from the synchronizing signal detection circuit 31 to a signal line 41 represents the existence of the synchronizing signal on a signal line 21, the synchronizing signal switching circuit 32 outputs the synchronizing signal on a signal line 21 onto a signal one 43. On the other hand, when the absence of the synchronizing signal is represented on a signal line 21, the synchronizing signal on the signal line 42 is outputted to the signal line 43 by the synchronizing signal switching circuit 32 and outputted also on the signal line 22. Thus, mis-operation and mis-setting is prevented.
