Title: Original conveyor
Inventor: HAMANO HIROAKI
IPC: B65H7/06
Filed: 1986-11-19
Abstract: PURPOSE:To make original insertion resumable at once even if pulling out an original due to an insertion miss, by stopping the detection of a subsequent paper jam by plural original detecting devices installed along a conveying route when reverse operation against the original conveyance is carried out. CONSTITUTION:When an original is inserted from a guide plate 1 and the tip is detected by sensors PS0 and PS1, an insert roller 10 is pressed to a feed roller 2, while a stopper is retreated, and the original is conveyed. And, when the tip is detected by a sensor PS2, paper feeding for sheets of copying paper 30 and 31 is started, but if these sensors PS0 and PS1 come into an on-state each, a paper jam detecting timer is started, so that a paper jam is detected by signal timing of each of sensors PS3-PS5. Here, when the sensor PS1 comes to off from the on-state in these sensors PS0 and PS1, it is so judged that the original is pulled out of an inserting part, therefore a conveying system is stopped and simultaneously the paper jam detecting timer is cleared. Thus, when the original is pulled out due to an insertion miss, original insertion is made resumable at once.

Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To provide a level detecting circuit and its detecting method for exactly detecting the change in resistance value even when oxide are formed on a resistor such as a fuel gauge. SOLUTION: A calculation-processing part 8 samples an analog signal outputted from a fuel sensor 7 to convert it into a digital signal, and calculates the quantity to be measured to output it as a signal to be detected. A switching circuit 3 operates at another timing than the above sampling period. A pull-up resistor 6 allows the calculation-processing part 8 to obtain sufficient resolution to convert an analog signal into a digital signal, and determines the magnitude of current flowing from a battery power supply 1 for removing insulations such as oxides formed on the resistor of the fuel sensor 7. A diode 4 feeds current 11 from a 5V power supply 2' to the fuel sensor 7, and restricts current 12 from the battery power supply 1 to connect it to the 5V power supply 2'.  A Zener diode 9 operates so that an analog signal inputted to the calculation- processing part 8 becomes an input signal below supply voltage of the calculation-processing part.

Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To make it possible to effectively use light made incident from between pixel electrodes, by providing a reflection layer reflecting the light made incident from an opening part to the opening part side below the opening part between plural pixel electrodes. SOLUTION: This device is provided with plural pixel electrodes 12, and displays an image by reflecting the light made incident on the pixel electrodes 12. The reflection layer 7 reflecting the light made incident from the opening part S to the opening part S side is provided below the opening part S between plural pixel electrodes 12. Then, for effectively using the reflection light from the reflection layer 7 as signal light, layer thickness of a liquid crystal layer 14 and the width of the opening part S are set so as to become d1 /d2 >=5 when the layer thickness of the liquid crystal layer 14 is defined d1 , and the width of the opening part S is d2 . Thus, the signal light is increased (a diffractive light component is reduced), and the image becomes bright, and a contrast ratio is increased also. Further, since even a part between the pixel electrodes 12 is contributed to a display, the image without a joint between the pixel electrodes 12 is realized, and the image is smoothened.

Filed: 1990-10-18
Abstract: PURPOSE:To increase an ON current and to improve a switching speed by forming an opposite conductivity type semiconductor layer on the surface of a contact region, and forming a P-N junction in which hot carrier is trapped. CONSTITUTION:A P<+> type contact region 18 is formed so as to bring into contact with a P-type silicon substrate 11, and an N-type layer 19 is formed on the region 18 to form a P-N junction. For example, when the concentration of P-type impurity of the substrate is set to 1X10<15> atoms/CC and the impurity concentration of the region 18 is set to 1X10<18> atoms/CC or more, the thickness and the impurity concentration of the layer 19 are so selected as to obtain a withstand voltage of 1-2 volts. Thus, hot holes generated as a drain voltage VDS is increased are trapped to the P-N junction, a reverse bias is applied to the substrate 11, and the width of a depleted layer generated near drain regions 13, 17 is increased, and hence an effective length of a channel is shortened, and a drain current is increased. Accordingly, since a large ON current is obtained, a switching speed is improved to perform a high speed operation.
