Title: Magnetic recording and reproducing device
Inventor: WATABE HIDEO
IPC: G11B15/08
Filed: 1989-01-20
Abstract: PURPOSE:To prevent the beginning/end of a tape from being erroneously detected by affording a rugged part to the inner surface of a hollow of a projecting part of a protective holder covering a light receiving element. CONSTITUTION:The light receiving element 14 is provided at the inner end of the hollow 13 of the projecting part 12 of the protective holder 11 molded of resin, and the inner surface of the hollow 13 is formed with a satin-like rugged surface by etching a metal mold. When the element 14 is fitted to the protective holder 11 of the above constitution, and a light emitting element is provided opposite to this element 14 so as to detect the beginning/end of the tape, external light 16 which is incident upon the hollow 13 without transmitting the tape is irregularly reflected by the rugged surface 15 of the inner surface of the hollow 13, and hence the quantity of the external light to reach the element 14 is extremely diminished. As a result, the beginning/end of the tape can be prevented from being erroneously detected due to the external light 16.

Title: Solidstate pick up unit
Inventor: OOTA YOSHIO
IPC: H04N5/335
Filed: 1979-02-05
Abstract: PURPOSE: To prevent the black flow phenomenon and to improve the picture quality, by increasing the bias charge voltage of bias charge supply transistor and taking the charge transfer transistor into cut-off state.  
     CONSTITUTION: The unit consists of charge transfer transistors TV, T 1 , T 2 , T n ..., charging MOS transistors Q 1 , Q 2 ..., and photo diodes D 1 , D 2 .... The potential of the point C of charge transfer stage is kept higher than that of the transfer point B during the vertical blanking period. Since the charge pulse VCH in the drive pulse is fed to the transfer stage point B, the maximum potential is increased to VCH- VT. Accordingly, the high level of the pulse C is set more than VCH-VT. That is, by keeping the pulse C in high potential during the pulse period of the charge pulse VCH during the vertical blanking period, the potential of the transfer stage point C is kept higher than the point B with the capacitor CV, to interrupt the current bus arrow y. Thus, black flow phenomenon is avoided and sharp objected information can be obtained.

Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To obtain a good image with high image density without fogging by setting developing bias having the intensity of electric field high enough to remove the fogging occurring in a 1st developing area in a 2nd developing area. SOLUTION: The potential of an exposure part in the developing area is SP11 on an upstream side and SP12 on a downstream side, and the potential of a non-exposure part is SP21 on the upstream side and SP22 on the downstream side. Then, SP11 and SP12 are about 50 V and SP21 and SP22 are about 700 V, and each potential is nearly determined according to the performance(electrification performance, dark attenuation and residual potential and the like) of a photoreceptor. When the developer is applied in the 2nd developing area, the potential of the 2nd developing bias Vb2 is near to the ground level of about 100 V with reference to the potential of SP12. Therefore, the direction of the electric field is a direction where positively electrified toner is restored toward a 2nd sleeve member at the exposure part on the downstream side of a photoreceptor drum, so that fogged toner at the exposure part on the downstream side of the photoreceptor drum is recovered to the 2nd sleeve member.

Filed: 1992-01-28
Abstract: PURPOSE:To obtain a deodorant which has excellent deodorizing effect for odor existing anywhere in the life of people, especially for sulfur-based odor by supporting dithiocarbamic acid and/or a salt thereof and a reducing agent on a deodorizing solid to form. CONSTITUTION:When dithiocarbamic acid and/or a salt thereof is supported on a deodorizing solid a sulfur component thereof reacts with a sulfur based odor substance to bond, which enables the deodorizing of the sulfur based odor substance by absorption and removal thereof. But when the deodorant thus obtained is left alone for a long time, dithiocarbamic acid and/or a salt thereof is degraded by the action of oxygen in the air, posing a problem of failure to maintain deodorizing performance for a long time. To solve this problem, a reducing agent is arranged facing the deodorizing solid with respect to the dithiocarbamic acid and/or the salt thereof. The degrading of the dithiocarbamic acid and/or the salt thereof is checked by the action of the reducing agent thereby enabling to maintain the deodorizing performance for a long time.
