Title: Optical information medium
Inventor: AKIYAMA TETSUYA
IPC: G11B7/2433
Filed: 1991-12-02
Abstract: PURPOSE:To provide the optical information medium which executes recording, reproducing and erasing of information by irradiation with a laser beam, etc., can execute good recording by overwriting and withstands many rewriting and environmental changes. CONSTITUTION:Tantalum oxide or tantalum nitrooxide having the thermal conductivity higher than the thermal conductivity of an over coating layer 5 is used as the material of an under coating layer 2, by which the difference in the diffusion rate of heat between the under coating layer side and the over coating layer side is decreased and the unbalance of the temp. at the time of recording is decreased. A thin intermediate layer 3 essentially consisting of zinc sulfide is provided between the under coating layer 2 and the recording layer 4, by which the generation of peeling, etc., between the under coating layer 2 and the recording layer 4 are substantially prevented. Then, the good recording by overwriting is executed and the optical information recording medium which withstands many times of rewriting and environmental changes is obtd.

Title: Signal noise discriminator
Inventor: MAKINO SHUNICHIRO
IPC: G01T1/17
Filed: 1991-12-02
Abstract: PURPOSE:To correct a reference voltage in response to a fluctuation even when a noise level is fluctuated, to reply a signal only at all times regardless of the fluctuation of the noise level and to output a pulse for counting by providing a variable voltage supplying circuit on a discriminator. CONSTITUTION:When a noise voltage is boosted, a comparator 26 generates a variable voltage generating pulse 25 to increase the voltage of an inverting buffer 29. Thus, the reference voltage is boosted and the noise voltage is dropped, then the comparator 26 does not generate the pulse 25 and the voltage of the buffer 29 is dropped and then the reference voltage is dropped. When the voltage is dropped by a prescribed voltage, since the noise voltage exceeds again it, the comparator 26 generates the pulse 25 to boost the voltage of the buffer 29. That is, a signal noise discriminator 21 applies a reference voltage in response to the noise fluctuation voltage to a noninverting input of a comparator 13 of a signal discrimination circuit 10 by the action of the variable voltage application circuit 24. Thus, the voltage is dropped more than that at an inverting input, no coefficient pulse 7 is generated and the signal and the noise are discriminated regardless of noise level fluctuation.

Title: Conveyor device
Inventor: SHIBATA ATSUSHI
IPC: B65G47/68
Filed: 1992-11-27
Abstract: PURPOSE:To enable the automatic adjustment of work balance in the case of work balance being about to collapse due to the fluctuation of workhours, the trouble of a sewing machine and the degree of skill by providing a work balance adjusting means for adjusting work balance among work stations performing the same kind of work. CONSTITUTION:A host computer 100 and a number reader 39 are equivalent to a work-in-process number computing means, and the execution of processing during a conveyance control process works as a balance adjusting means. A work-in-process ratio during a carrier path editing process is inputted and stored in an RAM 101. Even when work has to be stopped in a work station ST6 due to some trouble, work-in-process is not increased only in the work station ST6, but the work-in-process numbers of the work stations ST6, ST7, ST8 are increased in the state of being close to the ratio of 1:1:0.5. The work-in- process of the work stations ST having different workhours and needing a lot of workhours is thereby prevented from being retained wastefully.

Title: Bit array converting system
Inventor: SHIBAZAKI SHOGO
IPC: G06F13/12
Filed: 1987-12-19
Abstract: PURPOSE:To facilitate the connection between the devices having different bit arrays by using a bit array converting means to convert the bit array set on a data bus with the bit inverting signal produced from a CPU or a peripheral device itself. CONSTITUTION:When a bit inverting signal S is equal to 0 in a write mode of a CPU to a peripheral device, the output of an AND gate 5 is equal to 0 and the output of an AND gate 6 is equal to 1 or 0 in response to the state of a bit D0. Therefore the output of a NOR gate 7 is equal to 0 or 1 and a bit DB3 is equal to 1 or 0 in response to the state of the bit D0. Thus a bit array is converted by the state of the signal S. Then an inverter 1 is turned on with RD=1 in a memory read-out mode. The 1 or 0 of the signal S is supplied to both AND gates 3 and 4 and the bit DB3 or DB0 is delivered from the inverter 1 via a NOR gate 2 to be turned into a bit D3 or D0. In the same way, the bit array is converted in accordance with 1 or 0 of the signal S.

IPC: G06F12/12
Filed: 1993-12-20
Abstract: PURPOSE:To shorten the overall access time of a system by considering the congestion information on the access path set to a main memory in a replacement system for cache blocks and then by preventing the accesses from concentrating in a specific access path. CONSTITUTION:A cache memory 2 sends the information on the access path set to a main memory 5 from a replaceable cache block to an access path monitoring mechanism 4. The mechanism 4 detects the congestion state of each access path based on the received access path information and sends these detecting results to a block selecting mechanism 3. The mechanism 3 selects an access path of the least congestion based on the congestion states of access paths detected by the mechanism 4. Then the mechanism 3 decides the cache block which uses the selected access path as a replacing block and sends the information on this block to the memory 2.
