Title: Optical disc reproducing device
Inventor: NAKAMURA HIROYUKI
IPC: G11B7/09
Filed: 1984-08-01
Abstract: PURPOSE:To attain low cost by detecting the DC component of a current or a focus error signal to drive an objective lens in the direction of focus. CONSTITUTION:When an optical pickup 1b is moved to the peripheral position on a disc 11 having a warp, the objective lens 2b is lowered from the neutral point in the natural state because of the warp of the disc 11 and the DC component of a focus drive current or a focus error signal is increased gradually. Then the optical pickup 1b is turned minutely in a vertical or nearly vertical direction to the disc 11 depending on the warp component of the disc 11 so that the neutral point of the vibration of the objective lens 2b vibration in follow-up to the facial deflection of the disc 11 is made coincident with the neutral point where the objective lens 2b is in the natural state or the neutral point when a precribed bias is applied. Thus, the focus error is decreased without using a special light emitting element or photodetector, and the optical axis of the objective lens is kept nearly vertical to the disc at the same time and the optical disc reproducing device with low cost and high performance is realized.

Abstract: PURPOSE:To produce hexagonal ferrite powder having improved magnetic properties, by dehydrating a coprecipitate of an iron hydroxide containing a specific metal in an azeotropic mixture of water with a water-immiscible organic solvent, and calcining the resultant dehydrated coprecipitate. CONSTITUTION:An aqueous solution of an alkali is added to a mixed aqueous solution of a salt of a metal selected from Pb, Ba and Sr with an iron salt to coprecipitate the salts at >=10pH. The resultant coprecipitate is then filtered to give an iron hydroxide coprecipitate of one or more metals selected from Pb, Ba and Sr. A water-immiscible organic solvent, e.g. toluene, is then added to the resultant coprecipitate to form a slurry, which is then subjected to the azeotropic distillation of the water with the organic solvent in the coprecipitate under heating, dried and calcined in the atmosphere of air. Thus, the aimed hexagonal ferrite, having a small particle diameter, and slightly causing the growth of ferrite particles since the calcination can be carried out at a temperature 100- 200 deg.C lower than that in the conventional wet coprecipitation method is obtained.

Filed: 1992-06-22
Abstract: PURPOSE:To improve the operability by providing a function displaying the arrival of a call even during system setup, storing the system setting content and restoring the state to the communication state to the processing unit. CONSTITUTION:When a call comes from an ISDN 6 in the system setting state, the information is sent from a communication control section 1 to a state monitor section 5. The monitor section 5 displays incoming call information on a display section 4. Then the user confirms the arrival of an incoming call. The user discriminates whether or not the call is to be received and implements key operation for the reception when the user desires the reception. The monitor section 5 stores the current state and the setting value set so far and restores the state to the communication enable state to make communication with an opposite party making a call. The monitor section 5 transits the state to the system setting state again in the state of end of communication to continue the system setting. When the user does not desire the reception, the monitor section 5 receiving the key operation of continuity of system setting allows the control section 1 to send a signal of incoming call rejection to the ISDN and transits the system setting state automatically.

Title: Signal transmitting system
Inventor: TAKAHASHI SUSUMU
IPC: H03M7/30
Filed: 1983-09-05
Abstract: PURPOSE:To improve transmission accuracy by finding differential data and the maximum value for every block formed by dividing PCM data at a scheduled time and using higher order bits as effective ones and cutting off lower order bits when high level signals exceed a scale value corresponding to the maximum value. CONSTITUTION:An analog original signal is AD-converted and, for example, a PCM signal of 15 bits is obtained. The PCM signal is then delayed by one sample time at a delay circuit 2 and inputted into a differentiator 3 together with 15-bit data. The PCM signal and 15-bit data are sent out to a transmission system as a differentiated signal DPCM of 16 bits. The DPCM is given to an adder 4 and added to the last output of the adder which is delayed by one sample time at another delay circuit 5 and accumulated (integrated). The accumulated data are DA-converted as 15-bit data and outputted as analog signals. In the course of encoding the DPCM, differential data between two samples adjacent to each other in time are transmitted and, therefore, the mean value becomes smaller. When a high level signal exceeds a scale value, higher order one is used as an effective one and lower order one is cut off. By transmitting the number of cut off bits to the receiving side, the transmission accuracy is improved with less number of bits.

IPC: H04W76/02
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To attain transmission power control with high accuracy, suitable for variable rate transmission without deteriorating the transmission quality. SOLUTION: An Eb/Io calculation circuit 11 calculates an Eb/Io value which is a ratio of the signal power Eb per but for each bit rate to an interference power Io per 1 Hz, based on the reception base band signal rs from a reception processing section 10.
