IPC: H02P7/29
Filed: 1979-05-11
Abstract: PURPOSE: To prevent the erroneous detection due to the charge of a commutation capacitor by an electromagnetic-switch actuation detecting circuit, by discharging the commutation capacitor before an electromagnetic starting switch is actuated.  
     CONSTITUTION: A starting switch 10 is switched to a normally open contact b at starting, and a forward-backward switch 11 is switched to a normally open contact b or e. Since the output of an operation amplifier 13 x  is a 1, a thyristor 14 d  of a commutation capacitor discharge circuit 14 is triggered, and the commutation capacitor 4 d  is discharged. Then, the potential at the negative input terminal of an operation amplifier 6 g  is decreased, and the output of the operation amplifier 6 g  is inverted. At this time, a capacitor 13 q  is charged via a resistor 13l. After a specified time, the output of the operation amplifier 13 x  is inverted from a 1 to a 0, a transistor 13 n  is conducted, an electromagnetic starting switch 2 or 3 is actuated, thereby an electric car is started.

Abstract: PURPOSE:To contrive reduction of variations in plate width, and excess plate widths, and improvement of the yield by predicting plate width variation amounts based on estimated temp. variation amounts and estimated rolling speed variation amounts and correcting tensions to neutralize that plate width variation amounts. CONSTITUTION:A temp. computing element 20 estimates a temp. variation amount  T and a computing element 21 calculates a stand-to-stand carrying time variation amount DELTAt based on a rolling load variation amount DELTAP, a screw down position variation amount DELTAS, and a rolling speed variation amount DELTAVR detected by detectors 16, 18, and 19 at the (i)th stand. A computing element 22 estimates a plate width variation amount DELTAWP based on the DELTAT and DELTAt. A tension computing element 24 obtains a tension correction amount DELTAtb compen sating that amount DELTAWP and performs a tension correction equivalent to the DELTAtb through a tension controller 26. Therefore, variations in plate width are made to be small and excess widths are reduced for improvement of the yield.

IPC: C08F14/18
Filed: 1995-03-17
Abstract: PURPOSE: To provide a magnetic recording medium suppressing the reduction of the thickness of the lubricant layer and the deterioration of CSS resistance even when the medium is allowed to stand at high temp. and low humidity by allowing a magnetic recording medium with a lubricant layer formed by vapor phase polymn. on the magnetic layer to stand under prescribed conditions. CONSTITUTION: A magnetic recording medium with a lubricant layer formed by vapor phase polymn. on the magnetic layer is allowed to stand at 30-100 deg.C and 50-98% relative humidity for >=1hr. By this aging, the reduction of the thickness of the lubricant layer can be suppressed even at high temp. and low humidity because the structure of molecules constituting the lubricant layer is altered. The effect of aging is not produced in the case of <30 deg.C and the reduction of the thickness of the lubricant layer because of scattering is caused during aging in the case of >100 deg.C. The effect of aging is not produced in the case of <50% relative humidity and dew condensation is caused on the surface of the medium to deteriorate the performance in the case of >98%. When the medium is allowed to stand for <1hr, the effect of aging is not produced.

Abstract: PURPOSE:To eliminate such a test pattern that produces the noise owing to the conflux of pulses, by leading the rise and fall of a pulse into a simulator. CONSTITUTION:An output of 0-X-1-X-0 is supplied to the gates 20 and 24 of a logic arithmetic circuit comprising NAND gates 20-24, etc. with the 1 piece of signal supplied to the gate 21 respectively, then the output of the gate 23 is turned into 0-Y-1-Y-0 to produce an uncertain state by the mutual logic operation of X, where X is the state of rise/fall of pulse. For instance, a test pattern with which 0 is supplied to the gates 20 and 24 along with 0-X-1-0 supplied to the gate 21 respectively is formed with the priority given to the occurrence of the uncertain state. As a result, the output of the gate 23 is turned into 0-X-0-X-1 to produce no uncertain state Y. Then the rise and fall of a pulse is led into a simulator to eliminate a pattern that produces the noise due to the conflux of pulses. Thus a test pattern suited to an LSI logic circuit, etc. is obtaind.

Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To easily and inexpensively form an insulating screen on a photoreceptor and to form through-holes at equal intervals by forming an insulating layer of photocuring dry film. SOLUTION: The photoreceptor 33 is rotatably supported by a supporting part and the leading edge of the photocuring dry film 21 is fixed at a specified part on a photoconductive layer 13. In a state that a thermal press-contacting roller 22 generates heat, the photoreceptor 33, the roller 22 and a take-up roller 19 are rotated in a specified rotation ratio, respectively. In such a case, the cover film for protection 20 on the backside of the film 21 is peeled by the roller 19 rotating counterclockwise, and the film 21 is tensioned to smooth wrinkles. The film 21 is brought into tight-contact with the layer 13 by a laminating method in which it is compression-bonded by the roller 22 whose surface is heated to about 115 deg.C. Thus, failure in image quality due to the effect of the joint of the end face of the film is avoided.

Abstract: PURPOSE:To ensure high accuracy for a slice level adjustment, by giving a readjustment to the slice level voltage in accordance with the input level every time a data pattern to be used for adjustment of slice level is received, and automatically holding a certain duty ratio. CONSTITUTION:When an edge detecting circuit 11 detects the initiation of a slice level adjusting pattern, a sampling pulse fS is generated from a sampling pulse generating circuit 2. On the other hand, in the period during which the output received a waveform shaping within the period of the pulse fS is at H level, the reference pulse f0 is counted at 6 through a sampling gate 9. The counting value of counter 6 is latched at a latch circuit 7 only when the data pattern within a sampling period is discriminated 10 as a pattern for adjustment of slice level. Then the slice level voltage VS obtained by giving a D/A conversion to the value held at the circuit 7 is adjusted in accordance with the input level of an input signal every time a pattern identical with a pattern for slice level adjustment is received. Thus a stable duty ratio is ensured after shaping waveform.
