Title: Device for dealing with film attached with magnetic recording part
Inventor: KONO TOSHIYUKI
IPC: G03B17/24
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To prevent magnetic information from being faultily reproduced by inhibiting a film from being fed and constituting a device that the magnetic information is not reproduced when a noise detection means judges that the device is under a noise environment. SOLUTION: A noise amount obtained by a magnetic head 8 is read out. A reproduced output amplifying a voltage value obtained by the head 8 through electric impetus from the outside of a device by an amplifier is transmitted to a control circuit 20. When the rise of a voltage waveform equal to or above a predetermined voltage value is obtained, the circuit 20 recognizes it as one noise. Then, the total noise amount produced in a given time based on the inputted reproduced output is counted as the number of pulses and the counted result is read out as the noise amount. When the measured noise amount is equal to or above a reference noise amount, warning display is performed on a display device.  Namely, in the case of discriminating that the inside of a camera body 1 or the surrounding environment of the body 1 is under a noise environment, only the warning display is performed without performing film feeding operation by a film feeding motor 4.

IPC: H01M2/18
Filed: 1994-08-29
Abstract: PURPOSE: To prevent the break through by the corrosive elongation of a lattice body by shaping a bag-shaped separator such that it forms a curved arc, with its starting point as the rear of the rib part of a base contacting with a negative electrode, wrapping the negative electrode. CONSTITUTION: For this lead-acid battery, lead-calcium-tin alloy is used for both lattices of a positive electrode 1 and a negative electrode 2, and a bag- shaped separator 3 wraps the negative electrode 2. The base part 5 of the separator 3 in contact with the negative electrode 2 draws an arc in the shape of a curve, with its starting point as the rear of the rib part 4 projecting on the side of the positive electrode 1. This prevents the break through of the separator 3 by the use at high temperature, and also improves the charge acceptability by the use with high load. Moreover, shaping it in the said curve will produce a gap between the separate 3 and the negative electrode 2, and improve the diffusion property in the vicinity of the negative electrode 2, and suppress the sharp rise of the concentration of electrolyte.  So, the potential of the negative electrode during charge is optimized, and charge shortage ceases to occur.

Abstract: PURPOSE:To enhance the breakdown voltage of a semiconductor device without the on-resistance being increased, by forming a p<+> type well layer so that the depth thereof is at most equal to that of a p type base layer including a channel part. CONSTITUTION:On an n type semiconductor substrate 1, a power MOSFET comprises an insulating gate 3, a p type base layer 5 including a channel part 5a which is formed on the surface of the semiconductor substrate directly below the insulating gate, an n<+> type source layer 6 which is formed on a part of the surface of the p type layer, and a p<+> type well layer 7 which overlaps with the p type base layer 5 without including the channel part 5a. Now, the p<+> type diffusion layer 7 is formed by implanting impurities, B ions, into the surface of the substrate prior to the formation of the insulating gate, and the diffusion depth thereof is then so controlled as to be less than that of the p type base layer 5. As a result, the distance between the adjacent MOS cells is shortened, and the electric field relaxing effect is increased, thereby the breakdown voltage of the device is enhanced.
