Title: Optical disk recording and reproducing device
Inventor: SHIBATA HIDEAKI
IPC: H04N19/00
Filed: 1993-10-06
Abstract: PURPOSE:To reproduce a high definition television signal by decoding each read encoded data by a standard television signal decoding means and a local decoding means used in an encoding means. CONSTITUTION:One read encoded data string is subjected to decoding processing in the same manner as conventional, and the other is inputted to the local decoding means surrounded with a long and short dash alternating line and is processed. An adder 107 in each decoding processing outputs decoded data X1 of odd numbered fields and decoded data Xr of even numbered fields to a frame synthesizing circuit 118. The circuit 118 transposes data X1 and data Xr with respect to time to output the picture data in one frame period of the high definition television signal to a second selector 111. At the time of reproducing the high detinition television signal, the selector 111 selects the signal in the high level and outputs it to an output terminal. Thus, the circuit scale is not extended or the cost is not raised.

Title: Charged particle beam exposure system
Inventor: NISHINO HISAYASU
IPC: G01R15/22
Filed: 1990-09-20
Abstract: PURPOSE:To quicken the time of setting an amplification circuit and to enable high-speed drawing by inserting a sample and hold circuit between a signal processing circuit and the amplification circuit. CONSTITUTION:A sample-and-hold circuit 20 samples and holds output signal S0 of sample-and-hold signal SH supplied from a control circuit 12 to output it to an amplification circuit 18. The signal SH samples a signal value of the output signal S0 during a stable period and holds it for a suitable time. Hold signal SOUT is amplified in the amplification circuit 18 and outputted as deflection drive signal DDEF; however, setting time in this case is determined only by the setting times of the sample-and-hold circuit 20 and the amplification circuit 18 themselves. As the result, it is unnecessary to take much of the blanking period of blanking signal BK, so that wasteful time other than a time necessary for exposure can be saved.

Abstract: PROBLEM TO BE SOLVED: To easily reproduce a newly stored recording medium preferentially when the recording medium is replaced by recognizing and storing the newly stored recording medium when the recording medium stored at a storage part has been exchanged. SOLUTION: Every time when an MD(Mini Disk) 11 stored at a magazine 12 is exchanged, TOC information which is a data peculiar to a disk being recording at the read area of all MD's 11 in the magazine 12 is read and is for example recorded at a memory 28 of a system controller 27.

It is checked whether the MD's 11 have been exchanged or not and normal reproduction continues if no priority reproduction switch 26 has been operated if no MD's have been exchanged.  The exchanged and new MD's 11 are preferentially reproduced and the priority reproduction operation is ended if reproduction is completed and a normal reproduction operation continues.

Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To realize fast lock control by locally performing lock control for sharing main storage. SOLUTION: The lock control for respective processors 201-204 is performed by lock request controllers in cache units 205 and 206 to which the processors 201 to 204 are connected according to the state of a lock variable. Each lock request controller once receiving a lock request or unlock request looks up in a lock address register which holds the address of the lock variable to refer to the lock state stored in the corresponding lock status register. As the state of the lock variable, not only a table which merely shows that individual devices are in lock or unlock states, but also various states are defined. For example, ULE shows a state wherein it is confirmed that none of the devices secures a lock. Consequently, a lock is speedily obtained without confirming the states of other devices.
