Filed: 1984-10-30
Abstract: PURPOSE:To obtain an n-bit converter following an analog input signal in high speed with simple structure by using a charge coupling device (CCD). CONSTITUTION:In a 3-bit CCD converter using a 3-phase clock, an input analog signal VIN is injected in a channel under the 1st transfer electrode 101 of the 1st stage as the storage amount of the electric charge at the timing of the leading of the 1st phase phi1 of a transfer clock. The electric charge injected in proportional to the quantity of the input analog signal is transferred under the transfer electrode 102 in the leading timing of the 2nd phase phi2 of the transfer clock and transferred under the transfer electrode 103 in the leading timing of the 3rd phase phi3 of the transfer clock. In this case, a voltage a half of that of the transfer electrode 103 is applied to the 1st transfer electrode 104 of the 2nd transfer stage. The potential of the electric charge is doubled succeedingly after that and the value of the low-order bit is decided and at the point of time when the value of the least significant bit is decided, the value of each bit is delayed synchronously with the phi4 by delay devices 143-145 respectively and extracted at the same time as a digital signal from output terminals B3, B2, B1.

Title: Turbo molecular pump
Inventor: ASHIDA OSAMU
IPC: F04D19/04
Filed: 1990-08-30
Abstract: PURPOSE:To prevent adhesion and accumulation of cooled reaction products inside a pump by circumferentially arranging plural magnetic poles in locations that allow magnetic fields to extend into a rotor, producing eddy current inside the rotor rotating at a high speed, and heating the whole pump with Joule heat. CONSTITUTION:Plural permanent magnets 11 are fixed on a base 10 which faces and confronts the lower end surface 2c of a rotor 2. Consequently, the permanent magnets 11, whose magnetic poles N and S are polarized in the same orientation in the rotational direction of the rotor 2, are circumferentially arranged at intervals so as to provide magnetic poles N, S alternately inverted. Each magnetic field A produced by each permanent magnet 11 forms its magnetic path inside the rotor 2 across the lower end surface 2c of the rotor 2. With this arrangement, as the rotor 2, while rotating at a high speed, passes through the magnetic fields A one after another, eddy current occurs for canceling changes of magnetic fluxes occurring inversely inside the rotor. As a result, the rotor 2 is heated by Joule heat.

Title: Disk detecting device for video disk player
Inventor: OOTA AKIO
IPC: G11B19/10
Filed: 1985-10-16
Abstract: PURPOSE:To prevent a malfunction caused by such objects excepting for a disk as hands of the users or service operators, tools, etc., by providing >=2 detecting means for the detection of the inserting or mounting state of the disk. CONSTITUTION:When such objects excepting for a disk as hands of the users or service operators get into a video disk player, both the 1st and 2nd light receiving parts 21 and 22 are shielded from the light. Then a disk discriminating circuit 25 decides the absence of a disk and controls a player control 5. Thus an initial action mode is set or an initial waiting state is kept as it is. Furthermore only the part 21 is shielded from the light and a lift ring 27 is moved down after the presence of a disk is once decided. Here the part 22 is not shielded from the light owing to the move-down action of the ring 27 despite the revolution of a main motor. Thus it is decided that the mounted object is not equal to a disk and an instruction is given to the control 5 from the circuit 25. Then the ring 27 is moved up again to the upper end rest position and reset to a disk waiting state.
