Inventor: KONO MASAKI
IPC: C22C38/00
Filed: 1995-02-14
Abstract: PURPOSE: To produce a nonoriented silicon steel strip excellent in intra-plane nonorientative properties and suitable for rotary apparatus by using a steel stock having a specified compsn. contg. Sb and Sn and specifying the finishing temp. in hot rolling, the coiling temp. and the draft in cold rolling. CONSTITUTION: The stock for a silicon steel strip is subjected to hot rolling and is thereafter subjected to a cold rolling to regulate its sheet thickness to a final one, which is successively subjected to annealing to produce a nonoriented silicon steel strip. In this method, as the stock for the silicon steel strip, a steel contg., by weight, <=4.5% total of Si and Al, <=1.5% Mn, <=0.1% P, <=0.15% total of one or two kinds of Sb and Sn is used. Moreover, the rolling finishing temp. in the hot rolling is regulated to 600 to 750 deg.C, the coiling temp. to <=550 deg.C and the draft in the cold rolling to 75 to 85%. By this method, the silicon steel strip excellent in intra-plane nonorientative properties, i.e., ringing properties can be produced with good productivity and operability.

Title: Maximum electric power follow-up control method for solar light power generation system
Inventor: NAKAZAWA TAKASHI
IPC: H02M7/48
Filed: 1995-02-14
Abstract: PURPOSE: To speedily transfer to proper maximum electric power follow-up control when the sunshine increases thereafter even if the output voltage of a solar battery drops at low-sunshine time. CONSTITUTION: A command value voltage Vset which increases in steps of width Vstep is added to the control signal of an inverter, the current output electric power Pnow of the solar battery is compared with the value obtained by increasing or decreasing last output electric power Ppast by set electric power Phist where a dead zone is set, and the command value voltages Vpast and Vnow are increased or decreased in steps of width Vstep according to the comparison result to set a next-time command value voltage; when the output electric power is in the dead zone, the command value voltage Vnot is forcibly decreased with the step width Vstep to set a next-time command value voltage and the inverter is driven under maximum electric power follow-up control.  If the output electric power of the solar battery drops below a set value Pmin at low-sunshine time, a voltage at which the inverter can be driven is regarded as a lower limit of operation irrelevantly to the last output electric power Ppast and the output voltage Vcell of the solar battery is lowered to drive the inverter continuously.

Title: Liquid jet recorder and recording head cartridge
Inventor: HIRANO HIROFUMI
IPC: B41J2/01
Filed: 1989-02-03
Abstract: PURPOSE:To obtain a recording head cartridge high in quality and releability without any dot deviation by a method wherein a part to be detected which is attached to each recording head is detected with a detector fixed to the main body while a carrier is being scanned, and discharge timing of each recording head is controlled. CONSTITUTION:Before recording operation is started, a CPU 7 firstly scans a carrier 1 from a home station to a recording area position. At that time, a detector 4 firstly detects a home detection board 1a of the carrier 1 (a little longer cycle T1 pulse) and then detects respective boards to be detected 3 Bd to 3 Yb in an order of respective recording heads 3B, 3C, 3M, and 3Y (synchronizing pulse of S2, S1). A CPU 7 refers a detection waveform of this signal CS to a reference clock Ts in the CPU 7, detects an amount of deviation DELTAS3 from a reference position (timing) thereby, and stores it in a RAM 9. Then, since the CPU 7 performs recording correcting discharge timing by referring to the slippage amount DELTAS3 stored in the RAM 9 in recording an image, an ink dot is recorded at a regular position and when many colors are brought out by superposed recording of color ink, ink dots are superposed on one another with excellent precision.

Title: Manufacture of tooth profile product with boss
Inventor: YOKOYAMA MICHIHIRO
IPC: B21K1/30
Filed: 1987-02-05
Abstract: PURPOSE:To manufacture a tooth profile product holding a long punching life by using a female die in tooth profile having a mirror face with tapered inlet port by setting to the lower part shape of a bossed blank and the punch setting to the upper face shape of the blank. CONSTITUTION:The bossed blank 3 prepd. in advance is placed between a punch 1 and female die 2 to push the punch 1 down to the lower part. The lower part shape of the punch 1 is of the shape set to the upper part shape of the blank 3 and there is no gap between the blank 3 and punch 1, so a forming metal is sufficiently led to the tooth crest of the blank 3. The taper at the angle of 20-150 deg. is provided at the inlet port of the female die 2 and yet formed in a mirror face, so the blank 3 is passed through with less friction resistance and the surface of a tooth profile product 3' is smoothly formed. Moreover the press pressure of the punch 1 is dispersed by the taper and the working can be performed by reducing pressure for the female die 2 and punch 1 and the counter bearing of the punch 1 is less, so the die life is further extended.

Filed: 1995-02-14
Abstract: PURPOSE: To provide a power circuit which is small in power consumption and can use a small-capacity capacitor as for a power circuit which functions to take DC electric power out of an AC power source through a switching element and an accumulator element. CONSTITUTION: A rise-time voltage level detection part 11 detects the rising of an inputted AC voltage waveform and outputs an on signal to a switch part 12. The switch part 12 having received the signal switches on to charge a capacitor 6 connected to output terminals 5c and 5d, and also supply electric power to the outside. Further, a drop-time voltage level detection part 10 detects the falling of the inputted AC voltage waveform and outputs an on signal to the switch part 12. Then the switch part 12 switches on. Then the voltage level detection parts 10 and 11 output the off signals in a period, wherein the voltage is high, represented by the peak time of the AC voltage to turn off the switch part 12. At this time, the capacitor 6 begins to be discharged to supply the electric power to the outside.
