Abstract: PURPOSE:To perform excellent auto-tracking without being practically affected by the change of wavelength of a light source even if the wavelength of the light source is changes, by setting such correspondence relations between the distribution conversion direction of a luminous flux section intensity distribution converting means and the direction of the division line of a tracking optical sensor that they are equal to each other. CONSTITUTION:The light source, a means which converts the section intensity distribution of the luminous flux emitted from the light source to a specific direction, a pickup lens 14, a sensor lens 18, and a two-divided optical sensor 28 which obtains a tracking signal are provided. In this case, the distribution conversion direction of the luminous flux section intensity distribution converting means and the direction of the division line of the tracking optical sensor 28 are in such correspondence relations that they reactically coincide with each other. For example, a two-divided optical sensor 30 which obtains a focusing signal is provided, and the sensor 30 and the tracking optical sensor 28 are arranged in approximately equivalent positions with a beam splitter 26 between them with respect to the sensor lens 18. Thus, good auto-tracking is performed without being practically affected by the change of wavelength of the light source even it the wavelength of the light source is changed.

Abstract: PURPOSE:To recover a subordinate station in a stand-by state by automatically disconnecting the subordinate station connected owing to malfunction, by providing a means of connecting line wires to the subordinate station in response to a signal from the subordinate station, a means of resetting the connections a certain time later, and a means of disabling the resetting operation with a signal from the subordinate station. CONSTITUTION:A master station is provided with transmitter-receiver 1 and connected to the subordinate station by radio. When answer signal f2 is transmitted from the subordinate station, FF9 of the master station is set to place the master station in a transmission state, and RY-2 operates to connect line wires L1 and L2 to the subordinate station. After a certain time, the output of a timer circuit opens a gate to excit RY-8, and reset signal f3 is outputted to reset FF of the subordinate station to recover the subordinate station in a stand-by state. If a dial pulse is generated within the prescribed time, FF8 is set and the gate is not opened, so that resetting operation is not performed. This reset signal generating means should be disabled to operate even during the generation of an interphone mode signal and transfer mode signal.

Title: Turbo molecule pump
Inventor: OKAWADA TAKESHI
IPC: F04D19/04
Filed: 1985-07-31
Abstract: PURPOSE:To make it possible to exhaust at high speed even under low vacuum by arranging a wedge-shaped vortex flow groove on both the outer periphery of a rotor and the inner periphery of a stator respectwely, and communicating one partition of the vortex flow groove to a suction side stage and its other partition to an exhaust side stage. CONSTITUTION:In a rotor 1, a moving blade groove 4 and a wedge-shaped vortex flow groove 5 are dug on a suction side and an exhaust side respectively. On a stator 3 opposite to the rotor 1, a stationary blade 6 and the wedge-shaped vortex flow groove 7 are dug on the suction side and the exhaust side respectively. The moving blade groove and stationary blade groove can perform both functions as an axial flow blade and a screw groove type molecule pump to produce practicable high compression ratio and high speedy exhaust function. Consequently, since the exhaust function can be effectively carried out up to about 10 Torr, a higher exhaust speed can be taken even under low vacuum state.

Abstract: PURPOSE:To execute a stable development of a high quality by constituting a titled device so that a number of revolution per unit time of a magnet roll of the time when a magnetic powder scraping means is abutting on the surface of a non-magnetic sleeve becomes lower than a number of revolution of the time when said means is being separated from the surface of the non-magnetic sleeve. CONSTITUTION:At the time of non-development, when a number of revolution of a magnet roll 11 is set to <=1/2 of a number of revolution of the time of development, a load applied to a doctor and developer control member 15 and a non- magnetic sleeve 10 is reduced, and also a deterioration of a developer 18 is prevented. It is because the developer 18 on the non-magnetic sleeve 10 moves smoothly and is separated easily from the non-magnetic sleeve 10, comparing with the case the magnet roll 11 is stopped completely. On the other hand, if the number of revolution of the magnet roll 11 remains a number of revolution which is not changed so much from the time of development, a developer bank is generated in the vicinity of the doctor and developer control member 15, and an excessive load is applied.
