Title: Waveform equalizing circuit
Inventor: TONAMI JUNICHIRO
IPC: H04B3/06
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent delayed convergence of a factor depending on characteristics of a reproduced signal and divergence of the factor due to increase in determination errors by providing calculation means for calculating a control signal to adaptively control, based on a predetermined tap factor among a plurality of tap factors, the other tap factors. SOLUTION: A reproduced signal obtained when a magnetic head H scans over a magnetic tape T is supplied to a waveform equalizing circuit A via a preamplifier 1 through a DC eliminating circuit 4. The waveform equalizing circuit A has a configuration in which a calculating circuit 41 is added to a transversal-type filter. Assuming that an LPF which provides a factor with which the maximum energy of a signal waveform is obtained is designated as an LPF 38, the calculating circuit 41 outputs a control signal which sets absolute values of tap factors respectively obtained by LPFs 36, 37, 39, and 40 at values not exceeding an absolute value of the factor of the LPF 38. Thus, interference among codes with respect to a waveform serving as a center can be suppressed, resulting in a stable convergence operation.

Title: Lead stroage battery
Inventor: YAMASHITA SHIGERU
IPC: H01M10/06
Filed: 1982-05-20
Abstract: PURPOSE:To enable a sufficient charging of a lead storage battery to be performed after the battery is left to stand after either discharging or resistance connection by forming a shallow and a deep electric-discharge condition in each positive plate. CONSTITUTION:Cold rolled plates made of an Sb-free alloy, after being punched into a grid-like form, are combined with positive and negative plates. Two sections of separators 4 and eight sections of separators 4 are located on the surfaces of each positive plate 3, and assembly is performed at a given pressure before formation is carried out in a battery jar under a given condition, thereby constituting a battery. Thus, by varying the quantities of electrolyte distributed in the battery by varying the numbers of separators 4 stacked on the surfaces of the positive plate 3, a shallow electric discharge is developed in parts containing a small quantity of the electrolyte thereby delaying the time at which these parts are inactivated, and a part of the positive electrode 3 remains in a shallow electric-discharge condition at the end of electric discharge. Owing to such constitution, when the battery is charged at a constant voltage after it is left to stand, charging is performed between the negative electrodes by using the parts (shallow electric discahrge parts) which are not inactivated as the rising points of the positive electrodes. Besides PbO2, a charging product, is a good conductor and activates even the inactivated parts in order.

IPC: H04N7/00
Filed: 1992-03-10
Abstract: PURPOSE:To provide the circuit in which error correction is correctly implemented regardless of a simple circuit configuration of a majority decision circuit only. CONSTITUTION:A 1st counter 15 uses a control signal of a MUSE signal as an enable signal and uses a field signal as a reset signal and outputs plural bits as position data. A control signal decode circuit 16 detects an address based on the result. A majority decision circuit 19 takes majority decision by counting prescribed data from a data input terminal 10 for plural number of times based on the prescribed address from the control signal decode circuit 16. The majority decision circuit 19 outputs a 2nd bit as a control signal by allowing 2-bit counters to act like a so-called majority decision circuit in which an output '0' or '1' among outputs '0', '1', '2', '3' is at '0 or L level' and an output '2' or '3' is at '1 or H level'.

IPC: B21B37/18
Filed: 1993-04-13
Abstract: PURPOSE:To improve the accuracy of plate thickness and to ameliorate the yield by outputting a target plate thickness whose state of change is given by the thickness, width and material of a rolled stock based on storage values of a target value and a measured value of the plate thickness. CONSTITUTION:The target value of the plate thickness is calculated based on each set value 5, 7 of a draft opening degree, a rolling load and a bending pressure and the measured value of the plate thickness is calculated based on these measured values 4, 6. The target plate thickness when the plate changes from the measured value of the plate thickness directly after the plate is bitten in to the target plate thickness is calculated. A correcting quantity coping with the difference between the target plate thickness and the measured value of the plate thickness is given to a roll driving system. Storage means 13, 14 are provided to store the target value and the measured value of the plate thickness directly after the plate is bitten in. A function means 15 is installed to output the target plate thickness whose state of change is given by the plate thickness, plate width and material of the rolled stock based on the stored measured value and target value of the plate thickness. In this way, the rolling load which changes in different shapes through the plate thickness, plate width and material of the rolled stock can be set.

Title: Solid-state image pickup device
Inventor: TANAKA SHIYOUICHI
IPC: H04N5/335
Filed: 1983-05-17
Abstract: PURPOSE:To improve an S/N ratio or resolution by arranging a potential barrier and a potential well under each transfer electrode of a VCCD, and transferring charges of respective potential wells through empty potential wells from the output terminal of the VCCD vertically in the opposite direction. CONSTITUTION:The channel 10 of the VCCD stores signal charges in potential well parts 10 (A, B, and C) having a deeper potential and separates respective potential wells by potential barrier parts 11 (A, B, and C) having a shallower potential. An N type bulk channel is preferable as the channel 10 of each VCCD and separated by a P<+> channel stop area 16. The signal charge stored in each potential well is transferred vertically through empty potential wells independently from the output terminal of the VCCD, and consequently the resolution and sensitivity of the CCD sensor which uses the VCCD are improved greatly.

Title: Alignment method of projected image for magnified projection type aligner
Inventor: SASADA SHIGERU
IPC: G03F9/00
Filed: 1994-04-25
Abstract: PURPOSE:To make it possible to expose the respective circuit patterns of a color liquid crystal display panel with high superposition accuracy with a magnified projection type aligner having a non-telecentric optical system. CONSTITUTION:Alignment marks P'1 to P'4' are temporarily projected onto a glass substrate for testing and their positions are observed by an alignment scope and are kept stored and held as position data. This substrate is replaced with a glass substrate 103 for normal exposure. The errors between the positions of the actual alignment marks observed on this substrate and the positions of the previously stored and held images of the alignment marks are calculated. A stage 107 is moved in at least a Z-axis direction (a direction parallel with the optical axis of a projecting lens 102) in such a manner that the errors are confined within the prescribed permissible range. The accuracy between the respective circuit patterns is maintained with high accuracy even with the exposure device having such optical system. The movement of the alignment light at the time of alignment does not arise and, therefore, the exposure of the undesired regions is prevented.

Title: Surface shape measuring instrument
Inventor: KANEKO REIZO
IPC: G01N37/00
Filed: 1988-04-08
Abstract: PURPOSE:To measure a surface shape with an extremely small load by driving a displacement sensor according to the motion of a probe so that the distance between the displacement sensor and a spring is held constant. CONSTITUTION:While the probe 1 does not contact a measurement surface 2, the leaf spring 2 is attracted by an electromagnet 5 and displaced to almost the center of the measurement range of the displacement sensor 4. This operation is carried out by operating an electromagnet driving circuit 9 by a controller 8 with the position signal of the displacement sensor 4. When the operation is completed, the current of the electromagnet 5 is fixed in the current state and initialization is performed. Then a frame 7 is put close to the measurement surface 3 to bring the probe 1 into contact with the measurement surface 3. Here, the contact load which is generated here can be set to an extremely small value, e.g. 10mug order nearly equal to Van der Waals force operating on the probe and measurement surface because the rigidity of the leaf spring 2 is extremely small. Therefore, the surface is prevented from damaging owing to contacting.

     CONSTITUTION: The rack 5 is reciprocated by the power of the press macine and the rataty shaft  6 is swung by the first fan type gear 7 engaging with the rack 5 by 180° or smaller angle. At the  initial and final points of above stated reciprocating motion, the rack 5 is energized by the speing  10 in the direction parting from the gear 7 or to both of reverse sides of rotation of the gear 7,  and besides, the rack 5 engages with the second and third gears 8, 9, contacting with the stopper  11 rigidly fixed to the gear 7. Just after the ending point of the reciprocating motion, the stopper  13 fixed to the shaft 6 contacts with the stopper 16a or 16b fixed to the side of the machine  frame, and the shaft 6 is stopped. Hereafter, the rack 5 is moved a little distance, and a clearance  is generated between the rack 5 and the gear 7 or 8. While this period, the stopper 13 is thrusted  against the stopper 16 by the thrusting force of the spring 10. Hereby, the swing lever 12 makes  a 180° swing through the shaft 6, and the carrier 14 is reciprocated over the distacne twice of the  length of this lever 12.
