Title: Automatic traveling vehicle
Inventor: HIRATSUKA KAZUHIRO
IPC: B61B13/00
Filed: 1990-06-08
Abstract: PURPOSE:To naturally and speedily bring a travel vehicle near an optimum route at the shortest distance by setting a correction quantity in the direction of a Y-axis to be much with the direction of travel as an X-axis in a present position at a long distance from the optimum route and increasing/decreasing the correction quantity in the rotary direction of the travel vehicle as it approaches the optimum route. CONSTITUTION:A deviation in the direction of the Y-axis at the present position as against a target position at the prescribed sampling time of the travel vehicle 1 where the direction of travel is set to be the direction of the X-axis is assumed to be DELTAY, and the deviation of the rotary direction of the travel vehicle 1 to be DELTAtheta. The correction quantity of DELTAY is made larger than the correction quantity of DELTAthetain a range where DELTAY is larger and the correction quantity of DELTAtheta is made larger as DELTAY becomes smaller. Namely, correction in the direction of travel is taken large when the travel vehicle 1 is at a long distance from the target position of the optimum route and the correction of the rotary direction is made moderate. The correction of the rotary direction is made large in the position near the target position, the correction of the direction of travel is made moderate and the travel vehicle is gradually brought near the target position and direction. Thus, the vehicle can be corrected to the target position and direction of the optimum route at the shortest time and route.

Abstract: PURPOSE:To maintain stably Se for a long period of time without crystallization thereof and to decrease deterioration in an electrostatically charging property by providing an Se-Te photosensitive layer on at least the surface side of an Se photosensitive layer and incorporating a specific ratio of As in the specified range on the surface side thereof.

The photosensitive body is made into, for example, the laminated constitution in which the lower layer is an electric charge transfer layer consisting essentially of Se and the upper layer is an electric charge generating layer consisting of Se-Te. The As expressed by the formula (X is the distance mu unit from the surface and Y is the content % of As) is incorporated into the region of 0.1mu-10mu from the surface of said photosensitive layer. A decrease in electric resistance that may result from crystallization of Se and the consequent failure in maintaining satisfactorily the surface potential are thus prevented. Zerconium tertrakis acetyl acetonato is further coated as a charge blocking layer on such photosensitive layer and thereafter a low resistance protective layer contg. conductive powder such as SnO or the like is formed theron. The electrophotographic sensitive body having a long life is thus obtd.

Title: Integrated circuit
Inventor: HAYASHI KENJI
IPC: H03K5/00
Filed: 1989-06-14
Abstract: PURPOSE:To output a reference signal to a peripheral circuit only in a normal oscillation state to prevent the malfunctions of an integrated circuit IC by adding a filter to the IC to output only the frequency components set in a specific range. CONSTITUTION:When an oscillation circuit 1 starts its working, an oscillation signal 2 is divided by a dividing circuit 3. Then a division signal 4 is outputted to a peripheral circuit 7 via a filter 5 as a reference signal 6. The cut-off frequency of the filter 5 is controlled by the set frequency of the circuit 1. The signal 6 is outputted to the circuit 7 as long as the circuit 1 is normally working. When the circuit 1 oscillates a higher harmonic, the signal is cut by the filter 5 and the signal 6 is not outputted. Thus it is possible to surely output the signal 6 only in a normal oscillation state and to prevent the malfunctions of the circuit 7 just with addition of the filter 5.
