Title: Draw type information recording medium and its recording device
Inventor: SAKURAI YUKIMITSU
IPC: G11B7/24085
Filed: 1989-12-27
Abstract: PURPOSE:To make the subject medium compatible with a read only optical disk by recording write management information of inherence of the medium to the medium itself and utilizing it after demodulation at the time of direct read after write (DRAW). CONSTITUTION:A disk 1 loaded into a disk drive 2 is written with information (video, audio and data) in a prescribed format under a tracking control in accordance with a guide groove by a disk controller 3. Then, a (host) computer 4 performs its prescribed read and write, while the disk controller 3 performs the demodulation of the management information to send out the demodulated management information to the (host) computer 4 as occasion demands. Thus, since a write parameter of the write management information is recorded to the medium itself, write information is inputted to the recording device, and on the contrary, the DRAW type optical disk as a usable medium becomes compatible with the read only optical disk 1 to be popularized without restricting the recording device.

Title: Step-up circuit of semiconductor memory
Inventor: IN TSUGUNORI
IPC: G11C11/407
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To accurately prevent a boosted voltage from being supplied too much and suppress current consumption by boosting the voltage according to the consumption in an active state. SOLUTION: When a high pulse of a sense control signal ϕDET is applied from a sense control circuit 20 to a boosted sense circuit 30, the potential at a sense node is affected corresponding to the level of the boosted voltage VPP. Then when a latch control signal ϕLAT goes up to a high level, a transmission gate turns on to generate a sense signal ϕPD which is low when the voltage VPP is high in level or high when the voltage is low. A boosting circuit 40 for activation becomes able to boost the voltage when the signal RASB has high-to-low transition and a stand-by boosting circuit 60 becomes able to boost the voltage when the signal RASB has low-to-high transition. The boosting circuits 40 and 60, therefore, boost the voltage alternately with the boosting control signal ≃PD which is toggled with the signal RASB.

Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To detect cell from another slave set while awaiting a call from each master set (including a public base station) of two kinds of a synchronous or an asynchronous system. SOLUTION: Each slave set has an SF1 interval register 11 and an SF1 counter 12 for reception timing of a super-frame (SF1) of a 1st system (e.g. for public use) and has an SF2 interval register 21 and an SF2 counter 22 for reception timing of a super-frame (SF2) of a 2nd system (e.g. for home use). In the case that the reception timing of the SF1 competes with the reception timing of the SF2, a contention management part 31 gives priority to the SF1. Furthermore, each master set of two kinds of the systems is registered and more than two slave sets are made inter-slave-set registration. Thus, missing of logic control channel from the two master sets is not caused and a cell from another slave set is detected simultaneously and all of calls from the registered master set and the other slave set are detected.
