Patent EP-0585925-A2 (EP)
Inventor: TAMAGAWA AKIO C O NEC CORPORAT
IPC: H02M3/07
Filed: 1993-09-02
Abstract: A voltage converting circuit of the charge pump step-up type includes a first circuit means for charging each of first and second capacitors with the voltage of a voltage source at a first timing. A second circuit operates to serially connect the charged first capacitor between a positive electrode of the voltage source and a positive voltage output terminal at a second timing so that a positive voltage which is a double of the voltage source voltage, is supplied from positive voltage output terminal. A third circuit operates to the charged first and second capacitors in series between a ground terminal and a negative voltage output terminal at a third timing so that a negative voltage which is a double of the voltage source voltage, is supplied from the negative voltage output terminal. Since the positive voltage and the negative voltage are generated independently of each other, a voltage variation on one of the positive and negative voltage output terminals caused by an external load causes no voltage variation on the other of the positive and negative voltage output terminals.

Abstract: A thin film head is formed with first and second magnetic layers (P1, P2) of Permalloy that compose a magnetic yoke with a transducing gap (16) and includes a seed layer (24) deposited under the second magnetic layer (P2). The seed layer (24) is made of Fe-N-Al or Fe-N. The seed layer (24) may be sandwiched between oxide layers of silicon oxide or aluminum oxide. The seed layer (24) is characterized by high magnetic saturation and high permeability. The thin film head can provide a higher write field without change in head dimensions, or alternatively provide a smaller gap length without reducing the effectiveness of the write field. Linear recording density can be increased and the level of the playback signal can be improved with the thin film head using the seed layer (24) disclosed herein.

Abstract: An information recording and/or reproducing apparatus is operable with a large-capacity recording medium (13) and is operatively connected with a host computer (16). The apparatus has a cache memory (114) for temporarily storing therein information transmitted from the host computer (16), and also has a write-back function and a write-through function. When recording by the use of the write-back function is designated by a recording designation flag (112), the maximum number of substitutions of defective sectors is automatically set to a given value for a write-back operation, and a mode display (12) indicates that a write-back mode has been selected. The write-back operation is inhibited by a write-back inhibit flag (113) according to the frequency of occurrence of the substitutions or the condition of a substitute area (73) to thereby enhance the reliability of recording information.

Abstract: If one page of recording is terminated, a carriage moves to a position at which a recording head is located opposite a cap. Then, the ink is discharged through nozzles of the recording head onto temperature detecting element within the cap. Temperature change of the temperature detecting element upon contact with the ink is output from a detecting circuit, and the normal discharge of ink is detected by discharge detecting means. In this way, the decrease in the ink remain or the detection of ink undischarge can be securely made.

Abstract: A piezoelectric sensor (60) is mounted on the cleaning blade (58) and/or the blade support member (62) of a blade cleaning apparatus contained within a electrostatic copying machine. The piezoelectric sensor generates a waveform (Fig. 2) indicative of the wear characteristics of the cleaning blade and pressure loading of the cleaning blade against the photosensitive surface (4). A detection circuit (70,71,72,74) monitors the waveform generated by the piezoelectric sensor to predict the imminent failure of the cleaning blade due to wear and damage. The detection circuit also monitors the waveform to detect a build up of frictional and adhesional forces between the cleaning blade and the photosensitive surface and adjusts the pressure loading through a feedback loop to extend the usable life-span of the cleaning blade. Thus, unscheduled maintenance due to sudden and unpredictable failure of the cleaning blade can be avoided and the usable life-span of the cleaning blade can be extended.

Abstract: Apparatus for controlling a system including a linear amplifier (109) processing a plurality of carrier signals (111-114) of a multi channel carrier system alters the phases (by 131-134) of one or more sources of the multi-channel signals in response to a detected peak envelope power (in 153) or of a peak to average power (in 152) ratio at regular scheduled intervals. This reduces the peak envelope power to average envelope power ratio and enables the reduction in the power rating required by the amplifiers handling the multi-channel signal.

Abstract: Background   
It is very important that the driver circuit provides a sufficient base current to the power transistor because otherwise said power transistor might come out of saturation and can be damaged. In praxis it can occur that the charging capacitor providing operating current for the driver circuit has no sufficient charge to ensure required base current for the power transistor. 
       Gist of the invention   
It is an object to ensure that in all modes like switching from OFF to ON or from Standby to ON or during operation of a protecting circuit a sufficient base current for the power transistor is provided. According to the invention circuit means are provided ensuring that after switching the supply from OFF mode or from Standby mode to normal ON mode said charging capacitor (CP05) is fully charged before said switching voltage (Us) appears at the base of said power transistor (TP10). Especially said charging capacitor (CP05) is continuously charged during Standby mode or a delay circuit is provided for introducing a delay time between switching ON the circuit and the occurrence of the switching voltage (Us) at the base of said power transistor (TP10). 
       Advantages   
It is ensured that in all different modes like switching from ON to Standby or from Standby to ON or during protection operation or during repeatedly switching between ON an OFF sufficient base current for the power transistor is provided and there is no danger that the power transistor is damaged by insufficient saturation

Abstract: A bordering tool for connecting a plurality of sheets or film bundles by bordering allows the outer edge of the metal sheet to be set upright, then to be tilted over and finally folded over, i.e. the bordering operation can be completed in just one single working step. For this purpose, a bordering jaw is provided on the underside of a top part of the tool and, as the said top part is lowered, it comes to rest on the bottom part of the tool in the region of the die, which raises the outer edge of the metal sheet. The bottom part of the tool is divided into two in such a way that a relative motion between the two parts is brought about with the aid of the blank holder of the top part of the tool, which blank holder strikes the metal sheet, and this relative motion is intended, on the one hand, to raise the outer edge of the metal sheet and then to fold the outer edge over completely, whereupon the second part of the bottom part of the tool in turn executes a relative motion relative to the first part, which has already come to a standstill following its downward movement. <IMAGE>

Abstract: In an image forming apparatus for forming a binarized image upon adding on additional information without degrading image quality, a mode signal assumes an "H" or "L" level. When the mode signal is at the "H" level, a pattern in which a binarized output attains the "H" level for two successive pixels appears in a low-density area of the image formed, thereby indicating the start of data representing additional information. When the mode signal is at the "L" level, additional information is represented by the level of a control signal  f . The binarized output is controlled in such a manner that the spacing of black pixels becomes an odd number of pixels in a low-density area of the formed image in a case where the control signal  f  is at the "L" level and an even-number of pixels in the low-density area of the formed image in a case where the control signal  f  is at the "H" level. In other words, the additional information is expressed by indicating "0" when the spacing of black pixels is an odd number and "1" when the spacing of black pixels is an even number.
