IPC: B23K26/00
Filed: 1993-02-23
Abstract: PURPOSE:To automatically generate NC data for character marking only by inputting characters by an operator on a keyboard by extracting skeleton lines from bit map digital data on the font of an inputted character and converting them into vector data. CONSTITUTION:A character string operation part 5 inputs a character string from the keyboard 15, etc., and stores it in a data base part 21 through a data base access part 7. An NC data generation part 13 reads data on the character string, registered in the data base part 21, by a data base access part 7 and a character data processing part 9 separates the character string data into characters and receives dot string data corresponding to the characters from the vector font file of a font file 23. In another way, the bit map data in the bit map data file are converted into dot string data according to specific algorithm to obtain the dot string data, thus generating the NC data for character marking.

Abstract: PURPOSE:To obtain a steady steam generating rate in a waste heat boiler by detecting the rate of generated steam in the waste heat boiler disposed in the downstream of an incinerator to control the amount of waste materials fed into the incinerator and/or amount of burning air supplied to the incinerator. CONSTITUTION:The high-temperature burnt exhaust gas that is generated in an afterburning chamber 10 by burning gas which has been generated in a rotary kiln type incinerator 1 by burning waste materials is recovered its heat, and so, is cooled by a subsequent waste heat boiler 2. The amount of steam generated in the waste heat boiler 2 is detected by a steam flow rate detector 4 in the middle of a main steam pipe 3, and is signalled to a steam rate indicator controller 6 via a signal transducer 5. A comparation is made at the steam rate indicator controller 6 between the generated steam amount and the steam amount setting, and as a result, an output signal is supplied to a waste materials feeding device actuator 8 in order for the steam amount setting to be adhered to. Then, the waste materials feeding device 7 feeds the waste materials so that the set steam generating amount may be adhered to. By actuating a burning air controller 11, the burning air forcibly supplied by fan 9 can be controlled.

Abstract: PURPOSE: To let the tape recorder automatically stop surely with a simple mechanism by letting a detector which drives the unlocking mechanism of operators respond to a rotator which approaches to and detaches from a rotator rotating in cooperation with and irrespective of tape running.  
     CONSTITUTION: An SW slider 12 is turned by the operation of plural operators 2 which are put in required operation states to turn an idler lever 15 thereby letting an idler 16 approach to or detach from a flywheel 19 rotating irrespective of tape running and a drum 21 rotating in cooperation with the tape running 11 provided to a take-up or feed reel turntable 20. By the operation of the recording-playback operator, the rotating force of the wheel 19 is transmitted to the reel turntable 20 via the idler 16 and drum 21, whereby the tape is run. When the tape reaches its final end, the reel turntable 20 stops and there is no more deviating force of the reel turntable to a friction member 24 nor turning of a tape stop positin detecting lever 31, then an automatic stop mechanism lever 32 is contacted to a cam 323 by the rotation of the idler 16. This causes the lever 32 to move to turn an unlocking lever 34 which in turn moves an unlocking detention part 35, whereby the operators are unlocked and the tape recorder is automatically stopped.

Abstract: PURPOSE:To generate a timing signal and a reference signal using a single detector by constituting a rotary encoder which generates the timing signal synchronized to a type position formed on a type wheel and also generates a reference position signal of type wheel in a wheel driven by a worm member. CONSTITUTION:A detector wheel 92 rotates through reception of a drive force from a worm gear 30, and a detection conductor 93a rotates by one pitch while the worm gear 30 rotates once. Immediately after rotation of a motor 50, a detection conductor 93b on the detector wheel 92 contacts a detection brush 94b because said detection conductor 93b is set to the reference position of a type wheel 13 at a ratio of one against one, when a carriage is positioned at the first line. Consequently the position of the type wheel 13 can be confirmed at a resetting signal generated. Later brushes 94a, 94b contact the detection conductor 93a and timing signals T and T' generated at first are allowed to meet prearranged types of the type wheel 13, and keep the latter in rotation until a signal T which corresponds to a designated type 15 is generated.

IPC: H01S5/0683
Filed: 1991-02-28
Abstract: PURPOSE:To prevent deterioration and heat runaway caused by application of an excessive current to a semiconductor laser by providing a means which predicts a light emission amount to a light quantity control device of the semiconductor laser. CONSTITUTION:When an automatic light quantity control start request APCREQ is sent from a print sequence control means 2, D and (d) which are output to a light emission current control circuit 6 are initiated. D is data for rough adjustment and (d) is that for fine adjustment. When a laser light emission signal LON is turned 'true' for opening a gate of a light emission current switching circuit 8, a laser light quantity comparison control means 3 counts up or counts down a digital value of the output D and (d), thereby a light emission current circuit 7 changes a laser current Il flowing in a semiconductor 10. After D and (d) are turned '0' and LON is turned 'true', rough adjustment light emission current count data D is increased by one; thereafter, a predicted value PDPRD of light emission amount when data D is further increased by one is compared with a target light quantity APCTGT; if it is the target light amount APCTGT or more, fine adjustment is performed.
