Title: Magnetic recording medium of belt-driven type
Inventor: OCHI MAKOTO
IPC: G11B5/73
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To improve durability, dispersion properties and dispersion workability of a coat liquid, and obtain a belt-driven type magnetic recording medium most suitable for high-density recording, by specifying the amount of a lubricant included in a magnetic layer. SOLUTION: A tape cartridge 10 using this magnetic recording medium (recording tape) 20 has following features. The recording tape 20 having both ends wound to a pair of tape reels 15, 16 is guided along a predetermined running course by guide means 22, 24, 25 and 26. An inner face of a driving belt 30 is supported in a movable fashion buy a plurality of belt-supporting means 32, 34, 36 and 38, and an outer face is always held in touch with the recording tape 20 at least at two points. A magnetic recording layer of the recording tape 20 includes a fatty acid ester lubricant. The amount of the lubricant in the magnetic layer is 3-6 pts.wt. to 100 pts.wt. of magnetic particles. If the amount of the lubricant is not larger than 3 pts.wt., a viscosity of a coat material becomes high and, dispersion properties and workability are lowered.  If the amount exceeds 6 pts.wt., not only a head becomes dirty with the lubricant, but a friction between the belt and tape is decreased which makes it impossible to impress a predetermined tension to the tape, thereby causing a running failure.

Filed: 1986-06-11
Abstract: PURPOSE:To stabilize image density by variably constituting the changed potential of an electrostatic charging means for charging the surface of a photosensitive body and increasing the charged potential of the photosensitive body in accordance with the increase of leaked light generated at the time of closing a liquid crystal optical shutter. CONSTITUTION:The charged potential of a photosensitive drum 1 is varied to Vx by shorting resistors Ra-Rc to control the charged potential. The setting of a tap and the setting of the Vx are determined in accordance with the leaked light of the liquid crystal shutter. Namely, the transmitted light of the liquid crystal shutter is controlled by adjusting the light quantity of a light source at the time of opening the shutter, but the optical output of the shutter is changed in accordance with the dispersion of the leaked light generated at the time of closing the shutter. At the time of large quantity of leaked light, the initial charged potential is set to a high level by considering attenuation based upon the leaked light, and in case of small quantity of leaked light, the initial charged potential is set to a low potential VOB in accordance with the reduction of the leaked light.

Title: Starting circuit
Inventor: UEKI YOUICHI
IPC: H02H9/02
Filed: 1979-10-19
Abstract: PURPOSE:To nullify the necessity of an expensive timer circuit by a method wherein a voltage drop generated in a current limiting element is monitored by a charging current of a smoothing capacitor, and the charging current is confirmed, and then, the current limitting elements are short-circuited. CONSTITUTION:When starting, if an input switch SW is turend ON, the charging current of a smoothing capacitor C flows via a current limiting resistor R. At this time, a transistor Tr and a transistor Tr2 which are installed to monitor the voltage drop across the resistor R caused by this current are placed in a continuity state. And then, when the charging approaches to the completion and the charging current decreases, the voltage drop generated across the resistior R becomes equal to or less than the sum of the voltage across a base and emitter of the transistor Tr1 and the voltage drop generated across the resistor RB caused by the base current of this transistor, thus, the transistor Tr1 and transistor Tr2 are in a nonconginuity state and the transistor Tr3 is in a continuity state. On this account, a starting relay A actuates to short-circuit the resistor R at a contact (a), and thereafter, power supply to an interruption load L and a driving circuit D is performed without running through resistors, from a power source.
