Filed: 1994-02-14
Abstract: PURPOSE:To supply the stable output to an AC power source and a welding power source by detecting the welding current by a current transformer, and supplying the current to the field winding of an exciter through a rectifier by the signal to generate the exciting output corresponding to the welding output. CONSTITUTION:The voltage is generated in the exciter winding 6 commonly used as an AC power source by the rotation of a rotor 19, and the voltage is generated in the armature winding 9 of the exciter to flow the current. This current is rectified by a rectifier 15, and the current flows in the field winding 8 to generate the magnetic flux. Then, the voltage is generated through the crossing of the armature winding 16 for welding of a stator 17 with the exciter winding 6 commonly used as the AC power source. The welding current during the welding operation is detected by a current transformer 4, and the output is limited by a control circuit 12. The voltage from an open-delta winding 18 is applied to the field winding 7 of the exciter, and the exciting output corresponding to the welding output is generated to the open-delta winding. This constitution supplies the stable welding current to the welding terminal through a rectifier 3.

Title: Print system and printer
Inventor: DOI JUN
IPC: G06F3/12
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To attain improvement in printer efficiency by changing a transfer system at one of a host device and a printer as well when the other one of the host device and the printer changes the transfer system. SOLUTION: When there is a device ID request, the printer prepares its own prepared data at the time of reverse transfer. This printer judges whether the second data transfer system can be operated or not. Namely, it is investigated whether a control program stored in a RAM 119 or the like of a laser beam printer 1000 corresponds to a packet system or not. When the packet system is enabled, a special character string is added to device ID data to be transferred to the host device and these data are stored. The device ID data are transferred to the host device by reverse transfer. When the packet system can be operated. The print data to be next transferred are predicted as a packet system and analyzing is prepared.  When analyzing the received data, leading six to several tens of bytes are investigated and when they are confirmed as header or packet system data, according to the result, processing is continued.

Abstract: PURPOSE:To shorten an editing processing time by storing an input KANA (Japanese syllabary) string in a separately provided buffer as a KANA-KANJI (Chinese character) mixed string, and performing a editing processing after selecting a a homonym. CONSTITUTION:When a conversion key is pressed after the KANA string is inputted and stored in a KANA buffer 10, a KANJI converting device 6 reads the KANA string out of the buffer 10, converts the string into the KANA-KANJI mixed string by using a KANA-KANJI conversion dictionary 7 and a grammatical information dictionary 8, and transfers it to a KANJI buffer 11. Then, when a homonym needs to be selected, the cursor of a KANJI parts is moved on a screen to a character to be changed and the conversion key is operated to display homonym candidates, one after another, thereby selecting one desired candidate. When an end key is pressed, the KANA-KANJI mixed sentence after the selection of homonyms is transferred from the KANJI-KANA converting device 6 to an editing control part 2 and further transferred to a character buffer 9 while its contents are edited successively. When the editing is completed, the sentence is transferred to a display buffer 5 and displayed on a CRT device 4.

Abstract: PURPOSE:To obtain large reduction effect with simple circuit constitution by setting the maximum sensitivity direction of a microphone, which detects the sound pressure signal of an original sound source and controls the driving of an additional sound source, toward the original sound source and the minimum sensitivity direction toward the additional sound source. CONSTITUTION:An additional sound source 2 is used so as to reduce the radiation power of original sound source 1 and sound pressure at a specific point, and a signal detecting microphone 3 which detects the sound pressure signal of the original sound source 1 and controls the driving of the additional sound source 2 is so placed that its maximum sensitivity direction is set toward the original sound source 1 and the minimum sensitivity direction is set toward the additional sound source 2. An error microphone 4 is placed where the sound pressure is to be reduced. Then an amplifier 6 amplifies the outputs of the signal detecting microphone 3 and error microphone 4 through an adaptive filter 5 and drives the additional sound source 2. Consequently, feedback from the additional sound source 2 to the signal detecting microphone is minimized, so the sufficient noise reduction effect is obtained only by the constitution of only the finite impulse response type filter.

Filed: 1984-02-02
Abstract: PURPOSE:To attain the change of microprogram in a short time and also to miniaturize the titled device by using a transfer control citcuit to transfer the content of a ROM to an write enable memory. CONSTITUTION:A microprogram transfer control circuit 5 transfers sequentially the content of a microprogram ROM2 to a microprogram RAM4 so as to correspond to the amount for one word of microprogram memory structure in the unit of 8 words. When the transfer of all words of the ROM2 is finished, the content of the RAM4 goes entirely to the same architecture as that of the conventional microprogram ROM and the content of the microprogram designated by a control signal 1 is outputted one by one word from the RAM4. In this case, since the ROM2 is constituted by an ROM IC in 8,192-wordX8 bit, the device is miniaturized and the change of the microprogram of 1 word is attained in a short time.

IPC: B65H7/04
Filed: 1990-01-31
Abstract: PURPOSE:To simplify a structure by concurrently using a turn member, to which a takeout roller is mounted, to serve as a constitutional part of a detecting means. CONSTITUTION:When a paper form P is taken out, the paper form P in a paper feed cassette is gradually lowered, and a turning angle theta of a turn arm 61 is increased in such a way as to theta1, theta2, theta3. A display part displays the paper form P in a full condition when the turning angle theta of the turn arm 61 is in a relation where theta<theta1, paper form P in a condition with its intermediate residual amount when the relation is theta1<=theta<theta2, paper form P in a condition with its residual amount left a little when the relation is theta2<=theta<theta3, and further the paper form P in a condition with no residual amount when the relation is theta3<theta. In such a way as mentioned, since the residual amount of the paper form P is detected by detecting a turning amount of the turn arm 61, it can be used to concurrently serve as a constitutional part of a detecting means, and cost can be reduced by decreasing a number of part items.
