Filed: 1990-10-11
Abstract: PURPOSE:To directly detect the deterioration of a pulse width duty characteristic of an optical output waveform by amplifying a monitor signal of an optical signal so as to detect a pulse width of a pulse signal. CONSTITUTION:An NRZ signal 11 is converted into an RZ signal 12 by an NRZ/RZ conversion circuit 1 and electrooptic-converted by a laser diode LD 4 in an LD module 3 via an LD drive circuit 2 and sent. Moreover, the optical output is converted into a pulse signal 14 by a limiter amplifier 6 via a monitor photodiode 5 in the module 3. A pulse width detection circuit 7 sends an alarm signal 15 when the pulse width duty of the pulse signal 14 is at the outside of a prescribed range. Thus, the fluctuation of the pulse width duty of the optical output waveform is detected.

Title: Loop coil train detector
Inventor: KUBOTA SHIGEO
IPC: B61L3/12
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a loop coil train detector capable of accurately detecting the existence of a train on a loop coil irrespective of environmental changes. SOLUTION: In a device for determining the existence of a train when the oscillation frequency of an oscillation section 3 having an LC oscillation circuit using a loop coil 1 as a frequency deciding element exceeds by 0.5% a reference frequency stored in a reference frequency automatic correcting section 5, if the existence of a train on the loop coil 1 is determined, the reference frequency is changed by specified % understanding that the train is in a stopped condition when the fluctuation of the oscillation frequency of the oscillation section 3 detected by an oscillation frequency counting section 4, which is lower than specified %, continues for a specified time.

Patent JP-S62133762-A (JP)
Title: Semiconductor device
Inventor: KOBAYASHI YUTAKA
IPC: H01L29/786
Filed: 1985-12-06
Abstract: PURPOSE:To obtain a highly reliable MOSFET which operates at high speed by a method wherein a P-N junction is formed in a semiconductor region under the gate insulating film and the wall of a conduction band is provided by the difference between the Fermi levels of the P-N junction. CONSTITUTION:A P-N junction is provided in a single crystal layer under a gate. Because of a diffusion potential due to this junction, a depletion layer spreads to the bottom (insulator) in the N-type region and the N-type region is pinched-off. Therefore, the interior runs out of carriers and a current does not flow in the N-type layer. Accordingly, in case a gate electrode 4 is zero potential, the state between a source and a drain is turned-OFF. When a positive potential is impressed on the gate electrode 4, the band of the single crystal Si layer in the vicinity of a gate oxide film 3 is pushed up, but the band is pushed up by the diffusion potential because the region coming into contact with the gate oxide film 3 is a P-type region. As a result, carriers are generated in almost the whole surface of this region in a low-energy state, that is, the Si layer, and the wide region of the Si layer is turned into a channel.

Abstract: PROBLEM TO BE SOLVED: To make it possible to calculate as one print in the number of prints in the case of double-sided printing and paper-backside printing, which uses the backside of used paper, by inhibiting the counting of prints in the case of the paper-backside printing. SOLUTION: A user of the printer is made to set whether paper-backside printing, in which printing is carried out by using the backside of paper whose one side has been already used, is to be carried out or not. When a printing paper is fed out, a printing control part 24 rotates a paper-feed roller 26 and a carrying roller 28, which are specific, to carry the printing paper. The printing paper passes a paper-backside-detection means 21, and the paper judged to be improper for the paper-backside printing as a result of the detection of the printing paper is ejected into a paper ejection port 3 via a paper ejection roller 27. On the other hand, the paper proper for the paper-backside printing is sent to a printing part 23 by the carrying roller 28.  In the case of the paper suitable for the paper-backside printing, the printing control part 24 stops the output of a signal for executing the increment or a counter which counts copies, so that the copies are not counted.

In such a way, the driving quantum of the photographic lens is operated by the focusing information from the area used for the exposure operation, therefore, an optimum exposure value is obtained, and also, the focus can be adjusted correctly to the principal field.

Title: Magnetic head
Inventor: NISHIMURA MASARU
IPC: G11B5/80
Filed: 1987-10-28
Abstract: PURPOSE:To prevent the falsification and misuse of a magnetic card and the degradation of recorded information by providing a superconducting film which protects the magnetized information of a magnetic film to the magnetic film. CONSTITUTION:The magnetic film 2 on which the information is recorded and reproduced by magnetization and the superconducting film 3 which protects the magnetized information of the magnetic film 2 are provided on a substrate 1. Recording and reproducing are executed by magnetizing the magnetic film 2 to record and reproducing the information by using a magnetic head while the superconducting film 3 is converted to a normal conducting state by subjecting the same to partial heating using, for example, a laser or the like or by passing the current above the critical point thereto. Reproduction by a system using the conventional magnetic head is thereby prohibited. The superconducting film 3 interrupts the magnetic field from the outside even if such magnetic field is applied to the card; therefore, the degradation of the information on the film 2 is prevented as well.

Title: Cleaning method for latent image carrier
Inventor: MATSUMOTO KENTARO
IPC: G03G21/00
Filed: 1991-09-26
Abstract: PURPOSE:To prevent toner scattering by rotating a cleaner carrying member at a slower speed than rotational speed at the time of cleaning process before the cleaning process. CONSTITUTION:When stopping time of a cleaning roll 10 is made long, the toner stuck to carrier in the cleaner 12 is made to be in a state of discharge, and the electrifying quantity is reduced. Thus, the stopping time of the cleaning roll 10 where the electrification quantity of the toner is reduced is grasped beforehand. If the cleaning roll 10 is stopped for more than this time, it is rotated at a reduced speed than at the time of the next cleaning process while the cleaning roll 10 is rotated. In this way, the electrification quantity of the toner stuck to the carrier within the cleaner 12 can be risen to a desired value. Therefore, when the rotational speed of the cleaning roll 10 is made faster and to be the original speed in the next cleaning process, the scattering of the toner from magnetic brush can be prevented.
