Title: Production of plastic optical fiber
Inventor: NAGAI AKIHIKO
IPC: G02B6/00
Filed: 1988-03-15
Abstract: PURPOSE:To obtain a plastic optical fiber having a low transmission loss by using specific polycarbonate as a fiber component and specifying a melt-spinning stage. CONSTITUTION:The polycarbonate having >=0.40dl/g and <0.60dl/g ultimate viscosity (20 deg.C in methylene chloride) is used as the fiber component. After the polycarbonate is once completely melted at >=260 deg.C in the melt-spinning stage, the molten polycarbonate is discharged from a spinning munthpiece without cooling the same down to the (m.p. of the crystal -20 deg.C) or below an is run for >=10cm length under the mouthpiece in a slow cooling region held at >=70 deg.C. The polycarbonate to be used in this embodiment is produced generally by bringing dihydric phenol and carbonate precursor such as phosgene into reaction. The resulted polycarbonate optical fiber has the good transmission loss and the uniformity of the fiber diameter in combination and is capable of greatly expanding the applications as the fiber for light transmission.

Title: Microcomputer
Inventor: KONISHI MASAYUKI
IPC: G11C16/32
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To easily evaluate a flash memory and also to simplify the circuit constitution, by measuring the time to be required for an initializing processing while counting the pulse signal of the output of a timer every time the number of clocks of a system clock reaches a set value when a CPU receives an erase signal. SOLUTION: When the erase signal is inputted to a microcomputer 1 and a CPU 11 receives it, the CPU outputs a timer starting to a timer 12 in order to generate a pulse signal needed for measuring of the initializing processing time of a flash memory 2. Then, the timer 12 outputs the pulse signal to a memory control part 13 every time the number of clocks of the system clock reaches the set value by sampling the system clock. The time to be required for the initializing processing of the memory is measured by counting the pulse signal of the output of the timer until the initializing processing is completed. At this time, the measuring time is calculated by the product between the output cycles of the pulse signal and the counted values. Thus, it is unnecessitated to connect the microcomputer 1 to the exclusive measuring device of the outside.

Abstract: PURPOSE:To shorten the time for operation and to improve workability by forming the part of a reaction chamber where a by-product sticks into a cassette so that said part can be attached and detached at the time of forming a deposited film on a base body. CONSTITUTION:The cylindrical base body 2 to be formed with the deposited film is installed in the reaction chamber 1 and a cylindrical cassette 3 is attachably and detachably fixed to enclose the base body 2. The inside of the reaction chamber 1 is evacuated to a desired degree of vacuum and the base body 2 is heated to a prescribed temp. by a heater. A gaseous raw material is then introduced from an introducing part 8 into the reaction chamber. The gaseous raw material enters the inside of the reaction chamber 1 via an aperture 4 of the cassette 3 and at the same time, a high frequency is impressed to a high-frequency electrode 5 to generate plasma between said electrode and the base body 2. The deposited film is thereby formed on the surface of the base body 2 and at the same time, the by-product sticks on the inside surface of the cassette 3. The by-product is, therefore, removed extremely easily from the reaction chamber 1 simply by taking out the cassette 3 after the operation.

Abstract: PURPOSE:To make a reading part so as to read an original righteously by constituting it to give load smaller than feeding force of the original to at least more than two spots parted at both sides of the original in the opposite feeding direction at an interval between a feed roller and a read roller. CONSTITUTION:An original 10 set onto an original table is fed one by one after being discriminated by a feed roller 12 and a separator 14, and delivered to a reading part of an image sensor 18 by a read roller 16. With this delivery, the original 10 is taken out one by one, having each one read in a main scanning direction X as feeding it in a sub-scanning direction Y. Here if the original 10 is fed by the feed roller in leaving it set in a state of being skewed intact, a tip of the original comes into contact first with either of two loading means 20, 20. If so, bending moment is produced in the original 10 with a side of the loading means 20 previously contacted as the fulcrum point, as in an arrow E, by load in the opposite feeding direction given to the original 10 from the loading means 20 previously contacted, and thus any skew of the original 10 is remedied.

Abstract: PURPOSE: To stably and aerobically treat an org. waste liq. at a low cost even when the BOD in the waste liq. is greatly changed. CONSTITUTION: A liq. 4 to be treated is introduced into an aeration tank 2, mixed with return sludge 5 and aerobically treated, then the mixture is separated into solid and liq. by a separator 3, and the separated liq. is discharged as a treated liq.

At this time, the flow rate of the liq. to be treated and the BOD concn. are measured respectively by a flowmeter 41 and a BOD sensor 42, and the measured values are outputted to a controller 43. The amt. of ozonated sludge necessary to compensate and average the BOD load change is calculated by the controller, and a pump 26 is controlled to attain the sludge amt.  Consequently, the BOD load change resulting from the raw water is compensated and averaged by the BOD load originated in the reformed sludge.
