Title: Image forming method
Inventor: TAKIMOTO MASATAKA
IPC: B41M5/41
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To provide an image forming method capable of easily peeling off a release agent for obtaining an image of high density and high resolution by exposing to high density energy light to an image forming material and peeling off the release agent. SOLUTION: An image forming material 10 having an image forming layer and a release agent 2 in this order on a carrier 1 is used and exposed to an image pattern of high density energy light, thereby reducing bonding strength between the carrier 1 and peeling off the release agent to form an image. Regarding this image forming method, a release end is formed on a zone outside an image forming zone under exposure, and the image forming material 10 having an image forming layer on the carrier 1 is used for exposure to an image pattern of high density energy light. Bonding strength between the carrier 1 and the image forming layer at the exposed part is thereby reduced, and the bonding layer or adhesive layer of the release agent 2 having both layers is pasted to the image forming layer and then the release agent 2 is peeled off to form an image.  In this case, a release end 6 is formed outside an image forming zone under exposure.

Filed: 1988-10-19
Abstract: PURPOSE:To surely select each input/output option by selecting the input/output option of a microcomputer based on the combination of control data written on the prescribed area of an EPROM. CONSTITUTION:The input/output option of the microcomputer is selected based on the combination of the control data X and Y written on the prescribed area of the EPROM 2, and malfunction such as simultaneous selection can be prevented from occurring. Thereby, when the control data is read out from the prescribed area of the EPROM 2, either third or fourth transistor is set at an exclusive state by a control circuit based on the control data, and pull- down or the state of a CMOS buffer, etc., can be selected as the input/output option of the computer. Also, a second signal is generated simultaneously when a first signal is generated at the time of reading out data, and the third transistor is set at a driving state compulsorily, and the fourth transistor at a non- driving state. Therefore, an output current larger than that on the computer flows to the EPROM 2, then, a mode is selected.

Title: Method and circuit for measuring propagation delay time
Inventor: TOMARU KENYA
IPC: H04B17/29
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To easily recalculate and remeasure propagation delay and also to easily deal with the dispersion or secular change of an analog element by monitoring the propagation of the inputted arbitrary data at an output point of a signal propagation system, detecting the delay between input and output and processing digitally this delay to calculate the delay time of the signal propagation system. SOLUTION: An optional pattern transfer circuit 1 sends an arbitrary pattern to a switch 7. A switch 6 cuts a path set between a signal input terminal 99 and a circuit 8 that is to be measured by means of the switch signal sent from a control circuit 5. A clock circuit (CLK) 4 inputs a time reference clock signal to a time measuring circuit 3 and starts the measurement of time, in response to the start signal of a pattern detection circuit 2. The circuit 2 keeps its operation until it detects the pattern that is transferred from the circuit 1 and notifies the circuit 3 of the end of the measurement, when the pattern is detected. The circuit 3 counts the input frequency of the time reference clock signal and obtains the value that is proportional to the propagation delay time of the circuit 8.

Title: Circuit of pulse charge type electric dust collector and the collector
Inventor: TERAI HIROSHI
IPC: B03C3/66
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To apply the voltage of a waveform approximate to the ideal one to the electrode of an electric dust collector by collecting once the electric charge accumulated in the collector electrode to a collecting capacitor without flowing backward the electric charge to a power supply. SOLUTION: A switch SW is turned toward a fixed contact T1 at time t1 by a timing control means C, and an LC resonance circuit I1 is formed and the forward current of a diode D1 flows. That is, the electric charge accumulated in a storage capacitor CS flows to an electrode EP of a dust collector. As a result, the absolute value of voltage VS reduces and the absolute value of voltage VEP increases. As the capacity of the capacitor CS is approximately equal to the electrostatic capacity CEP of the electrode EP, the increment of absolute value of voltage VEP is approximately equal to the decrement of absolute value of voltage VS. Then the current of the circuit I1 does not flow any more after time t2 , and the current flows to an LC resonance circuit I2 only. Furthermore, the reverse bias is generated at a diode D2 at time t3 and therefore no current flows thereafter.
