Title: Laser beam printer
Inventor: ABE MAKOTO
IPC: B41J2/44
Filed: 1986-07-25
Abstract: PURPOSE:To generate a beam detection signal always at accurate timing, by varying reference potential or the photoelectric conversion ratio of a photoelectric converting means stepwise on the basis of the rate of the emitting intensity of laser beam varied stepwise. CONSTITUTION:A D/A converter 11 converts the laser power level data D2 outputted from a laser driver circuit 2 to analogue data and the variable potential DELTAVth determined by resistors R21, R22 is outputted to a voltage adder 12. Since constant reference potential Vth determined by resistors R11, R12 is inputted to one of the terminals of the voltage adder 12, the added potential (DELTAVth+ Vth) of them is inputted to the inverting terminal of a comparator 23 as a reference level TH. Therefore, beam detection output based on beam emitting power inputted to the non-inverting terminal of the comparator 23 is subjected to waveform shaping to output a beam detection signal BD. By this method, the beam detection signal can be generated always at constant timing even when beam emitting power varies.

Title: Adjusting method for sound recording bias current
Inventor: KAGEYAMA YOSHIHIRO
IPC: G11B5/03
Filed: 1985-08-07
Abstract: PURPOSE:To improve the frequency characteristic by making a bias current flow to a sound recording/reproducing head of a two head type tape deck, generating a leakage magnetic flux in a gap part of the head, converting it to a voltage level by using a search coil and indicating it, and controlling the bias current so that the value becomes constant. CONSTITUTION:Whether a sound recording state is good or not is determined by a correlation of a characteristic peculiar to a head and a running tape. When a bias current flows to a sound recording/reproducing head 1 through a current regulator 5 from a bias transmitter 3, a leakage magnetic flux is generated in the vicinity of a notch of the head. When this continuous signal is converted by a search coil 10, and also displayed on a voltmeter 12 through an amplifier 11, a variation of the leakage magnetic flux can be confirmed in detail. Accordingly, when the regulator 5 is adjusted so that a value of the voltmeter 12 is kept constant, an adjustment of a sound recording bias current is completed, and a variance of a frequency characteristic can also be dissolved.

Title: Line connection control system
Inventor: MINAMOTO TSUNESUKE
IPC: H04B17/00
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To attain communication between slave stations in the case that there is no margin in transmission available power of the slave stations for direct communication between the slave stations by transmitting, a carrier for a slave station via a master station to the slave stations in due case that a carrier for a slave station cannot be sent due to a limit of transmission power but there is a margin for the master station. SOLUTION: In the case that a new channel connection request from a slave station -1 to a slave station 3 while the slave stations -1, 2 send one carrier each for communication, the slave station -1 allows a transmission power supervisory equipment 4 to send information of a fact of a small margin of only 0.6 dB in transmission available power of the slave station -1 to a master station 1. The master equipment 1 based on the information sets a channel via the master station equipment 1 according to the new channel connection request by using channel allocation devices 2, 2'. In the case that the other slave stations and a channel of one carrier are have been already set up and communication is conducted and a new call request is given to the slave set, a channel via the master equipment 1 is assigned without rejecting the request.

Title: Magnetic recording and reproducing device
Inventor: TAKEO AKIHIKO
IPC: G11B5/02
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction in the reproduced output caused by servo signal thermal mitigation and to obtain the tracking servo, which stably operates for a long time by setting the length of the servo signal recording bits so that the maximum reducing magnetic flux at the magnetic saturation in the recording bit of the servo signal in a recording layer is made smaller than the coercive force of the recording layer. SOLUTION: In the recording bits of the tracking servo signals, a reducing magnetic flux Hd is generated against the magnetic characteristic of a recording layer itself. If a magnetization M value is saturated with the flux Hd, practically no secular change of the magnetization M occurs. Conversely, the secular change of the magnetization M becomes large in the region where dM/dH in the magnetization curve is large. Thus, dM/dH is set to zero so that the magnetization M in a bit is saturated while the flux Hd is added in a recording bit, the secular change of the reproduced output caused by thermal mitigation is reduced.  Moreover, if a maximum reducing magnetic flux Hdmax is set smaller than coercive force Hc while the magnetization is saturated in the bit, a magnetization M saturation condition is maintained and the flux Hdmax , becomes smaller by a recording bit length λ/2 becomes small.

IPC: H04N5/232
Filed: 1993-07-14
Abstract: PURPOSE:To prevent passing over a focal point by decelerating the displacing speed of a lens near the focal point. CONSTITUTION:First and second filter circuits 50 and 60 are HPF for extracting the high frequency component of a luminance signal and respectively constituted so that cut-off frequencies can be 200kHz and 600kHz, for example. Integration circuits 54 and 64 integrates the respective high frequency components for each field and output them as focusing evaluation values V1 and V2. A relative ratio calculation circuit 70 calculates a relative ratio V2/V1 and sends it to a focus motor control circuit 110. The relative ratio V2/V1 is turned to a maximum value near the focal point. A control circuit 110 sends a control signal to a focus motor 3 so that the more the relative ratio is enlarged, the more the speed of the focus motor 3 can be decelerated.
