Title: Magnetic bearing device
Inventor: OTSUKI MASAAKI
IPC: F16C32/04
Filed: 1999-06-03

Title: Clock reproducing circuit
Inventor: HANABUSA TOSHIO
IPC: G11B27/28
Filed: 1985-09-02
Abstract: PURPOSE:To make a clock signal pursue the change of data line speed to which a PLL circuit only can not cope with by providing an AFC circuit to vary the clock signal in response to a prescribed-frequency signal of such as margin part recorded beforehand in a magnetic tape, to the PLL circuit. CONSTITUTION:If the data line speed further lowers, the reproduction frequency of the recording signal of the margin part lowers for a VCO signal from a voltage controlled oscillator 7. Accordingly, the level of the sample-holding signal from a sample-holding circuit 15 lowers for the frequency voltage signal from an FM converter circuit 11, hence the level-difference between the said two signals shrinks and also the level of a frequency error voltage signal added to a phase error voltage signal by an adder 5 decreases, and as a result, the frequency of a clock signal outputted by the oscillator 7 via a 1/2-frequency divider circuit 8 and a T/4-delay circuit 9 also decreases. Therefore, because of the AFC function by means of frequency-difference detection, the pursuable range of variation in the data line speed can be drastically extended by about 50% of the range of normal reproduction operation.

Title: Vacuum device
Inventor: EDAMURA MANABU
IPC: C23C14/24
Filed: 1992-07-21
Abstract: PURPOSE:To reduce water molecule adsorbed in a vacuum vessel and to shorten reevacuating time at a low cost at the time of returning the vacuum device to the atmosphere by introducing a gas having smaller water conc. than the atmosphere into the device and preventing the vacuum device from the intrusion of air from an opening part of the vacuum vessel. CONSTITUTION:The vacuum device 1 is evacuated with a valve 2 by an evacuating line 3 and a treatment is executed in the obtained vacuum. Also, at the time of maintaining or exchanging interior parts, the valve 2 is closed and a dried gas is introduced with a valve 4 from the supply line 5 of the dried gas into the device 1 so that the pressure in the device 1 become >=one atom. and furthermore is successively introduced to keep the pressure. Next, the gas is ejected from a gas ejecting opening 7 and a port 6 is opened. By ejecting the dried gas from the gas ejecting opening 7, it is prevented that the wet air of the outside intrudes into the inside. Thus, film quality is improved in the case of film forming since gaseous impurities in the vacuum device are reduced.

Filed: 1993-07-09
Abstract: PURPOSE:To shorten the time required for inputting a jump signal name and to reduce input errors at the.time of imparting the jump signal name to a jump signal in a CAD. CONSTITUTION:An operator selects a signal for imparting the jump signal name from a circuit diagram displayed on a display part 4 by operating a keyboard 6 and inputs the jump signal name to be imparted to the signal from the keyboard 6. A processing part 1 imparts the jump signal name to the selected signal and when it is unregistered in a storage part 3, registers it in the storage part 3. Also, in the case of imparting the already inputted jump signal name to the signal, the operator inputs a jump signal name list display request. Thus, a jump signal name list whose elements are the jump signal names registered in the storage part 3 is displayed on the display part 4. The operator imparts the jump signal name to the signal by selecting the jump signal name in the displayed jump signal name list.

Title: Processing system for individual line signal of satallite
Inventor: KAIYAMA AKIRA
IPC: H04B7/15
Filed: 1987-08-05
Abstract: PURPOSE:To apply a satellite line as an economical trunk line of an existing switchboard by adding only the transmitting/receiving function of a supervising signal to a signal converter and the transmitting/receiving function of the register signal to a satellite circuit control station respectively. CONSTITUTION:The supervising signal is transmitted and received in a pair with the call information on each talking line between an existing switchboard 1 and a signal converter 14. In an outgoing mode the supervising signal is sampled and branched into a common line signal device 10 via branching/inserting circuit 13. While the supervising signal received from the device 10 is supplied to a talking circuit 6 in an incoming mode. Then the device 10 converts the supervising signal branched from the circuit 13 into another form of signal to be put on a common control line 12 and also the supervising signal received from the line 12 into the form of an individual line signal to send it to the circuit 13. These converted signals are put into the line 6. The constitution of the circuit 13 is simplified since the bit positions of the call information and the supervising signal are already decided when they are transmitted on the line 6.

Title: Printer
Inventor: TSUKAMOTO TAKAHIRO
IPC: B41J11/42
Filed: 1985-09-05
Abstract: PURPOSE:To enable a printing medium having a wider range of thicknesses to be met by allowing the thicknesses of a printing medium to be selectively input and the speed of a paper feeder motor to be varied according to input. CONSTITUTION:When a small paper thickness is selectively input to a paper thickness information input section 1, and later, printing operation is terminated, a control 5 starts the control operation of a paper feeder motor drive 7, i.e. a stepping motor 10. Then if, for instance, the reference of a paper feed value is assumed to be 1/6inch and the movement amount per pulse of the stepping motor 10 is D, the expression 1/6inch=DX(P1+P2+P3) holds (P1 represents acceleration area, P2 constant speed area and P3 the pulse count of reduced speed area). If the paper thickness is small, the torque has only to be low, so the stepping motor 10 is relatively accelerated. That is, the motor 10 is accelerated to the speed V1 by the pulse count P1, and later, is moved at constant speed by the pulse count P2 whilst maintaining the speed V1 as it is. Further, the motor is operated at reduced speed by the pulse count P3 and then is brought to a stop.
