Filed: 1995-05-24
Abstract: PURPOSE: To discriminate the type of a recording medium and set an operation mode and at the same time, rapidly discriminate a loaded state and execute treatment by detecting the reflection factor of a loaded disk-shaped recording medium in a recording or reproducing device. CONSTITUTION: An optical disk or a magnetic disk 1 is loaded into a loading part 2 and laser beams are applied to a recording surface from an optical head 5. The reflection factor of reflection light from the recording surface is equal to or more than 70% on the optical disk and is approximately 15-25% in the magnetic disk. A signal for quantity of reflection light is extracted by an RF amplifier 6 and is supplied to a circuit 12 for detecting quantity of reflection light and the output is supplied to an A/D input port 11a of a system controller 11. When the controller 11 judges that the quantity of reflection light is equal to or more than 70%, it sets the processing of the RF amplifier 6 to a state for coping with the disk and initiates reproduction.  When it judges that the quantity of reflection light is small, it judges that a loading failure occurred, reversely rotates a loading motor 4, and executes eject operation.

Title: Gas circuit breaker
Inventor: NAKANE SHINICHI
IPC: F16K17/36
Filed: 1988-06-16
Abstract: PURPOSE:To obtain a gas circuit breaker without defect that a total flow rate is less than a separate maximum flow rate in a circuit-brake condition by correcting an arithmetic result of a flow rate data with a timer in operation multiplied by coefficient. CONSTITUTION:A condition correcting part 12 inputs the output from a total flow rate storage and arithmetic part 10 and a separate maximum flow rate storage and arithmetic part 11, and makes a correction so that the former will exceed the latter in the condition. Axis of abscissas shows the elapsed time and axis of ordinates shows the gas flow rate. For example, in a set period T1 of the first timer 5, at time t0, gas flow rate is Q1, at t1, Q1+Q2, and the separate maximum flow rate is Q2, at t2, Q1, at t3, zero. Till time t4, the circuit-brake condition is total flow rate LG1, separate maximum flow rate LK1 as the initial condition, and LG1>LK1. At time t4, the circuit-brake condition is set newly on a basis of each data observed. As for the total flow rate, (Q1+Q2) is multiplied by coefficient K1; as for the separate maximum flow rate, Q2 is multiplied by coefficient K2, but in the case of K1<K2, as the circuit-breaking condition is possible to be such as the total flow rate< the individual maximum flow rate, a correction is made so that the former will exceed the latter; LG2=LK2 after t4.

Filed: 1986-06-25
Abstract: PURPOSE:To highly accurately form a desired magnetic force distribution pattern in a low cost, by providing recessed or projecting section over the longitudinal direction of a roll and controlling the magnetic force distribution by means of the recessed or projecting section. CONSTITUTION:The magnet roll M has a four-pole constitution and is formed by injection molding a resin (nylon 12) dispersing about 80pts.wt. of a magnetic substance (ferrite) and magnetization-oriented with the magnetic substance at the same time. Since projecting section 111 and recessed sections 121 are provided on the peripheral surface of the magnet roll M, a sharp distribution is obtained at the N1 pole and a magnetic force distribution which is asymmetrically reduced in intensity on the downstream side of a developing section is obtained at the S1 pole. Therefore, the toner layer on a sleeve stably becomes thinner and, since the magnetic force suddenly drops at the downstream side of the developing section, the sharpness of developing and fog-free pictures can be obtained.
