Title: Image forming device
Inventor: SUZUKI HIROSHI
IPC: G03G21/00
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To prevent a device from being shifted to a power saving mode immediately by misoperation to eliminate that an image forming condition becomes prescribed display setting state by maintaining a power saving mode shifting reservation state until specified time elapses even in the case of operating a key for shifting to power saving mode. SOLUTION: By setting the device to the power saving mode shifting reservation state until the specified time elapses even in the case of operating the key for shifting to the power saving, the situation that the device is shifted to the power saving mode immediately by erroneous operation and the image forming condition becomes the previously set display set mode is prevented. Namely, in the case of operating a preheating key for shifting to the power saving mode, the device is set to the power saving mode shifting reservation state until the set time in a shifting timer 54 elapses, and the device is only shifted to the power saving mode by a power saving mode shifting means 51 after the set time elapses. Therefore, even in the case of advertently operating the preheating key for shifting to the power saving mode, the device is not immediately shifted to the power saving mode.

Title: Activating method of catalyst
Inventor: HINO MASAO
IPC: B01J38/06
Filed: 1983-08-25
Abstract: PURPOSE:To recover efficiently the activity of the catalyst with a small amt. of waste water to be treated even in case of a horizontal reactor by injecting dry steam to the deactivated catalyst packed in the reactor, spraying wet steam, and then injecting dry steam. CONSTITUTION:Dry steam is injected through a nozzle 2 to the deactivated catalysts 1-a and 1-b packed in a reactor 3 while keeping the catalysts packed in the apparatus 3 to remove the dust deposited and accumulated on the surface of the catalyst. Wet steam having <=0.4 wetness is subsequently injected to dissolve and remove a water-soluble poisoned substance accumulated in the catalyst. The catalyst is then dried by dry steam. This method has the advantage that the amt. of waste water to be treated is small as compared with the usual water washing method such as the dipping and the spraying method, and also has the advantage that the injection pressure of the steam can be utilized even in a horizontal reactor wherein the application of a washing method by spraying is comparatively difficult.

Title: Packet transmission system
Inventor: OKAMOTO YOSHIHISA
IPC: H04L12/70
Filed: 1989-06-16
Abstract: PURPOSE:To attain effective utilization of a line by aborting a 1st packet when a 1st packet for awaiting transmission is resident and a 2nd packet to be sent newly takes place and sending the 2nd packet to a packet exchange network in the succeeding packet transmission. CONSTITUTION:A packet generated by a transmission packet generating section 1 is stored in a transmission packet queue 2 provided for each logical channel and sent to a line by a command of a flow control section 5. When a command of transmission wait comes from a packet exchange, the transmission from the transmission packet queue 2 is stopped by a command of the flow control section 5. At the time of generating a packet from the transmission packet generating section 1 in this state, a transmission queue abort control section 6 references a value of a flag bit F in the transmission packet and when the bit F is logical '1', the packet with the flag being logical '1' in the transmission packet queue 2 is aborted and a packet generated newly is stored in the transmission packet queue. Thus, the transmission of a useless packet is prevented an the effective utilization of the line is attained.

Title: Ignition device
Inventor: SUGIURA NOBORU
IPC: F02P5/14
Filed: 1979-11-30
Abstract: PURPOSE: To improve the detection accuracy in a detector which detects a knocking signal from a comparison of the output from a knocking sensor with an averaged value of the knocking sensor outputs by setting the respective outputs in a comparable level relationship.  
     CONSTITUTION: There is provided the knocking sensor NS which detects electrically the vibration of an engine and provides a detection signal. The detection signal is fed into a high-pass filter HPF and band-pass filter BPF, by which the knocking frequency included in the detection signal is discriminated. The output from the band- pass filter BPF is half-wave rectified by a half-wave rectifier HR and inputted into a capacitor C9 via an amplifier AMP2. The output fromthe capacitor C9 is inputted into a comparator CO1 via an amplifier AMP3. The comparator CO1 is also inputted the output from the band-pass filter BPF and compares these both inputs. The comparator CO1 outputs a knocking signal to a knocking control circuit NC, only when the input from the capacitor C9 is larger than the input from the band-pass filter BPF, so as to control the ignition timing accordingly. There is further provided a means for reducing the amplifying ratio of the amplifiers AMP2 and AMP3 during a high-speed rotation compared to a low-speed rotation of the engine, thereby improving the comparison accuracy of the comparator CO1 at the high-speed rotation of the engine.
