IPC: H04B1/40
Filed: 1988-09-22
Abstract: PURPOSE:To apply data modulation from a state where a transmission carrier at voice communication is alive by using a control pulse generated by a press delay section to drive a transmission section. CONSTITUTION:A press delay section 2 synthesizes two signals, that is, a microphone press signal and a microphone press detection signal from a press detection section 1 and generates a transmission section control signal enabling the transmission state of a power amplifier circuit 16 or the like of a transmission section 11 of a radio equipment consecutively for a time from the start of receiving the microphone press signal till the detection of the end of voice transmission with the microphone press detection signal terminated therefrom and further nearly one sec in addition. Moreover, the microphone press detection signal outputted from the press detection section 1 activates a MODEM 20 to send a transmission output of a data from a transmission 10 from an antenna 18 for nearly one second after the end of microphone press. Thus, the transmission of data communication of a simple message is implemented efficiently for nearly net one second after the end of the voice transmission.

Title: Operation checking method for inverter
Inventor: OKADA TOMIZO
IPC: F23N3/08
Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To detect whether the adjustment of the amount of air supplied is made accurately or not in a boiler which uses an inverter to adjust the amount of air supplied. SOLUTION: The frequency of a current to be fed to a blower motor 7 is altered by an inverter 8, the rotational speed of the blower motor 7 is changed to adjust the amount of air supplied and the amount of a fuel to be supplied to a boiler is controlled to perform a combustion at three positions of high combustion, low combustion and stoppage. In a boiler 1 of such a type, a frequency detector 11 is provided to detect an operation frequency to be sent to the blower motor 7 by the inverter 8. Then, a frequency for checking operation is previously set between a frequency value for high combustion and a frequency value for low combustion. When altering the frequency by the inverter 8, an operation frequency detected by the frequency detector 11 is compared with the frequency for checking operation.  If the operation frequency altered passes the frequency for checking operation, the operation of the inverter 8 is determined to operate normally.

Title: Field effect transistor voltage-controlled oscillation circuit
Inventor: MAETA TADASHI
IPC: H03K3/354
Filed: 1987-09-25
Abstract: PURPOSE:To control the oscillation frequency and duty by connecting an FET for current control to a flip-flop circuit consisting of a buffer mode FET logic (BFL) circuit and controlling its base bias. CONSTITUTION:A node 55 is charged with charges of a capacitor 17 by an FET 19 for a current source and drops in potential V55, and other node potentials do not vary. When discharging continues until the potential of the node 55 rises above the potential V54 of a node 54 by the absolute value of a threshold voltage, an MESFET 14 begins to turn on when the MESFET 14 begins turn on, both the potentials V51 and V53 of nodes 51 and 53 fall and an MESFET 13 is cut off. This cycle is repeated continuously, so the flip-flop consisting of the BFL oscillates. Consequently, when the threshold voltage of the MESFET 14 varies and the duty of the oscillation waveform varies, a desired duty value is obtained by varying the gate bias of the FET 18 or 19 for the current source slightly.

Abstract: PURPOSE:To identify and trace a process route passed before an optional point and the contents of a process at the optional point by transferring information indicating the processing process of data between layers together with data. CONSTITUTION:Data which is sent out by a user program 16 is developed on a system buffer 11 and on this system buffer 11, the data is transferred from a higher function layer 151 to a lower function layer 155 in a function layer group 15 by a inter-layer transferring means 13. At this time, a passage identification information setting means 14 adds identification information on passed layers among pieces of characteristic identification information for identifying data processing process and kinds of respective layers 151 - 155 of the function layer group 15 to the data developed on the buffer 11. Consequently, what processing route data arriving at an optional point in the processor passes in at several points or previous function layers and how the data is processed can be discriminated.

Title: Heater disconnection inspecting apparatus and image forming apparatus
Inventor: OTAKE MASAKI
IPC: G03G15/20
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous operation of disconnection judgment by detecting that no AC power flows in an AC load and judging that a heater is disconnected in the case no AC power is detected even after a time or longer to stop a DC power passes. SOLUTION: When a heater disconnection detecting circuit 39 detects the disconnection of a heater, a timer circuit 44 is started. When the heater current becomes lower than the disconnection threshold value, a timer circuit 44 is started and after a prescribed time passes, a timer up signal 48 is sent to a system controlling circuit 33. The prescribed time is set to be a sufficiently longer period than the time duration from the complete stop of an AC power input 49 to the time when the DC power output 46 becomes low enough to stop the function of the system controlling circuit 33. After the time is up, in the case the heater disconnection detecting circuit 39 detects disconnection of the heater again, it is judged that the heater is disconnected and error information is written in an non-volatile memory 43.  As a result, it is judged that the heater is truly disconnected or that the AC power is disconnected and erroneous operation of an image forming apparatus is prevented.

IPC: B22D11/06
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To provide an edge dam block constituted in a way to eliminate burr due to metal leakage by preventing leakage of a molten metal between edge dam blocks. SOLUTION: An edge dam block assembled in a condition that an upstream side face 48 is engaged with a downstream side face 46 at a key fit relationship is used as a given route for deciding a boundary of a movable mold casting area, so as to form a rotatable non-end edge dam. The edge dam retains a molten metal in the casting area. The upstream side and downstream side faces of the adjacent edge dam blocks have such a shape to supplement each other for minimizing entering of the molten metal between the edge dam blocks. The key fitting engagement between the edge dam blocks avoids slippage of such a relative rectilinear movement that the edge dam blocks approach or are separated from the molten metal.  One of the adjacent engageable surfaces of the edge dam blocks has at least one protrusion 46, and the other engageable surface has at least one concave part 48 for accepting this protrusion.
