Title: Image forming device
Inventor: ISHIHARA NORIYUKI
IPC: G03G21/00
Filed: 1988-07-13
Abstract: PURPOSE:To evade the wasteful consumption of toner without causing faulty cleaning by controlling toner quantity on a part except an image area which is conveyed by a cleaning blade according to an environmental condition. CONSTITUTION:Toner band forming means is controlled by a toner band forming times control means which corresponds to the number of copies by a copy counter after an environment changeover switch responds to a temperature sensor to get in a toner quantity control mode and a toner band width control means and the toner quantity on the part except the image area which is conveyed by the toner blade is changed according to humidity. Thus, the faulty cleaning can be prevented from occurring and the wasteful consumption of the toner can be evaded. The image where density is not lowered can be formed without receiving the effect of the change of humidity and the number of copying times. The same processing as in the case of the change of humidity can be performed even in the case of the change of temperature.

IPC: B05B5/08
Filed: 1983-09-21
Abstract: PURPOSE:To obtain an always undeformable, uniform, an elliptic spraying pattern by providing an insulating material in front and the rear of an electrostatic oiling machine in the conveying direction of a material to be oiled. CONSTITUTION:The insulating plates 9a and 9b are provided in front and the rear of an electrostatic oiling machine T in the conveying direction F of a material 1 to be oiled, and the plates are installed oppositely in parallel by keeping a specified distance which is selected to be smaller than the outer diameter of an original oiling agent spraying pattern formed by the electrostatic oiling machine.

Title: Interface device
Inventor: ONO MOTOYASU
IPC: G06F3/00
Filed: 1987-07-10
Abstract: PURPOSE:To surely transmit the data produced asynchronously with each other to a CPU just with a single reading action by holding the state of the data signal synchronized by a synchronizing circuit via a monitor circuit in the activating timing of a read signal and then delivering the held signal state in the form of data. CONSTITUTION:For instance, a data signal DT is activated in the timing as shown in a diagram and therefore a JKFF 7 is set at the rise of a system clock SCK. Then a chip selection signal CS1 and a read signal RD are produced. Thus an FF 8 is set and the holding state of an FF 7 is held by the FF 8. This holding state is transmitted to a CPU as a signal STD via a 3-state buffer 10 during an active period of the signal RD. Hereafter the buffer 10 is set under a high impedance state when the signal RD is inactivated. At the same time, the FF 7 is reset.

Title: Semiconductor device
Inventor: TAKAGI OSAMU
IPC: H03K19/00
Filed: 1988-07-11
Abstract: PURPOSE:To reduce the noise without hindering the quick operation neither the high integration by supplying the latched output of an inverting latch means to not only the back gate of a second MOS transistor TR but also the gate of a third MOS TR and taking out the buffer output obtained by inverting an input signal. CONSTITUTION:The latched output of an inverting latch means 13 is supplied to not only the back gate of a second MOS TR 12 but also the gate of a third MOS TR 16 to take out the buffer output obtained by inverting the input signal. When a high level H is applied to the input voltage, the second MOS TR 12 is turned on and the output level falls; and when it falls in a certain degree, the latch output goes to H, and the third MOS TR 16 is turned on simultaneously with turning-off of the second MOS TR 12 and the output level is inverted to a prescribed low potential level without shooting. Thus, the noise is reduced with the simple circuit constitution without hindering the quick operation neither the high integration.

Title: Amplitude control system
Inventor: SPARKS STEPHEN T
IPC: H03G3/30
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To attain high speed and accurate amplitude switching regardless of its low cost. SOLUTION: Integration devices 32a, 32b in pairs connected in parallel are integrated in an automatic level control loop and switches S2, S3 are used to select either of the devices 32a, 32b. Since drive voltages 34a, 34b given to a level modulator 12 are stored in advance to each of the integration device pair in advance as initial values, settling of a system output signal 45 is disregarded, the amplitude of the test signal 50 is quickly and accurately switched so as to avoid a switching transient phenomenon. Even when a plurality of setting voltages are provided, one signal generator is enough and only the number of the integration devices connecting to the loop and the number of reference signals 40a, 40b corresponding to the setting voltages have only to be increased, then the circuit is realized easily at a low cost.
