Title: Switching power supply
Inventor: SASAKI MASATO
IPC: H02M3/28
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a switching power supply apparatus for reducing the power consumption of an apparatus in waiting condition. SOLUTION: A switching power supply apparatus converts an input AC voltage into a DC voltage with a primary side rectifying and smoothing circuit 2, and then converts a DC voltage to a high-frequency AC voltage with the switching operation with a main switching element 3. A high-frequency AC voltage is varied with a transformer 7 and is then given to a load 14 through rectifying and smoothing in the secondary side rectifying and smoothing circuit 11. At driving, a DC voltage obtained in the primary side rectifying and smoothing circuit 2 is input to a control circuit 5 via the normally-closed switch circuit 21 and drive resistor 6. When after the drive, a switch controller 22 detects that the main switching element 3 started the switching operation, the switch controller 22 turns off the switch circuit 21.  Therefore, a current does not flow into the drive resistor 6, thereby reducing the power consumption.

IPC: H03B5/32
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent a very small oscillation at application of power and to start the oscillation surely at a natural frequency by a start pulse. SOLUTION: When a power supply voltage Vdd rises by a power supply section 10, a 1st detection signal S21 is outputted from a detection section 20 in following to the rising and a 2nd detection signal S27 is outputted with a delay of the detection signal S21. The quantities of the levels of the 1st and 2nd detection signals S21, S27 are compared by a NAND gate 31, and its output is given to an inverter 32 and an NMOS 33, and a resulting start pulse S32 is fed to an input node N40 of an oscillation section 40. When the start pulse S32 descends, the NMOS 33 is nonconductive and the oscillation section 40 starts the oscillation at a natural frequency.

Title: Original pressure-contacting device of copying machine
Inventor: HIROSE AKIRA
IPC: G03B27/62
Filed: 1979-06-15
Abstract: PURPOSE: To let the pressure plate be stopped in a wide range of angle of inclination by using such plural springs which start acting at the different angles of inclination of the pressure plate.  
     CONSTITUTION: The angle of inclination of a pressure plate 24 is let θ, the moment by the own weight of the pressure plate M 3  and the moments by springs 35, 36 are let moments M 4 , M 5 . Now, if the moment M is assumed to be axis of ordinate and the angle θ of inclination to be axis of abscissa, the moments M 3 , M 4 , M 5  are expressed by curves F, G, H, respectively. Since the resistance force against turning of the pressure plate 24 is produced in the respective parts of the turning, the pressure plate 24 stops if the moments M by the elastic force of the springs are within the range enclosed by the curves I, J. The moments M by the elastic force of the springs are the composite of the moments M 4 , M 5  by the springs 35, 36 and are indicated by the dotted line K. If the angle of inclination is above the angle θ 5  of inclination corresponding to the point f of intersection of the dotted line K and curve I, it turns out that the pressure plate 24 stops.

Title: Network system
Inventor: TOSHIMA AKIHIKO
IPC: H04L69/40
Filed: 1990-03-28
Abstract: PURPOSE:To easily implement function change or the like of a network adaptor by loading a revision program to a nonvolatile memory in the network adaptor from a monitor via a trunk line network. CONSTITUTION:When a function change of a network adaptor 24 is required, a new program to realize the function revision or the like is loaded to a nonvolatile memory 13 in the network adaptor 14 from a monitor 25 of the network system via a trunk line network 21. When the revision program is loaded to the nonvolatile memory 13, the network adaptor 24 does not operate on a program built in a ROM 12 but operates on the loaded revision program. Thus, a job having a difficulty of execution such as replacement of the ROM while a power supply of a station is turned off is not required to realize the function revision or the like of the network adaptor.

Filed: 1986-04-04
Abstract: PURPOSE:To save the recording paper and to prevent the delay of the important information by using operator call means and a control means to reject the data communication to a data communication request which does not saisfy the prescribed conditions and at the same time allowing the call between the calling and called sides after calling and operator. CONSTITUTION:When an equipment set at the called side is called by the ringing tones, a CPU 5 transmits a called station identifying signal CED via a MODEM 6. Then the CPU 5 transmits the connected three signals, i.e., a standardized device signal NSF, a called station identifying signal CSI and a digital identifying signal DIS. The transmission of these signals is repeated until the reception of a standardized equipment setting signal NSS, a calling station identifying signal TSI and a digital instruction signal DCS are confirmed at the calling side in response to those three signals transmitted from the CPU 5. Then the signals NSS, TSI and DCS of the calling side are transmitted, the received signal TSI is stored in a memory 4. Then the numbersstored in the memory 4 are sequentially compared with the telephone numbers stored in a memory 3. When no coincidence is obtained from side comparison of numbers, a cut command signal DCN is transmitted. Then a circuit is opened.
