Title: Tape end detector
Inventor: INAJI TOSHIO
IPC: G11B15/08
Filed: 1981-09-04
Abstract: PURPOSE:To surely detect the jointed part of a magnetic tape and a reader tape to prevent malfunction, by detecting the magnetic tape end having the reader tape at its end optically and switching the tape running direction instantaneously. CONSTITUTION:When a reader tape 2a of a magnetic tape end is positioned to a counter part of a positioning tape guide 4, a light from a light emitting element 5 transmits the reader tape and is irradiated to a photodetector 6. Thus, the end of tape can be detected at the boundary of tape joint. Then, a pulse is generated from an output terminal only when the reader tape opposes to the guide 4, and an inverting signal is obtained. In this detection circuit, no effect is given to the operation of a comparator 14 even if dispersion exists in the sensitivity of the optical elements. Further, the inverting signal is outputted only when the tape changes from the magnetic tape part to the reader tape. Thus, the signal is outputted only at the end and not outputted at the beginning end, then no malfunction is caused.

IPC: G03G5/06
Filed: 1985-06-28
Abstract: PURPOSE:To obtain a laminate type electrophotographic sensitive body having very high sensitivity by using a specified polycyclic quinone pigment as a charge generating material in a charge generating layer and a specified hydrazone compound in a charge transferring layer. CONSTITUTION:A charge generating layer is made of a layer contg. a polycyclic quinone pigment represented by formula I and a charge transferring layer is made of a layer contg. a hydrazone compound represented by formula II. The charge generating layer contains the charge generating material to the utmost limit so as to obtain satisfactory absorbance, and the layer is preferably formed as a thin film of 0.01-1mum thickness so as to efficiently implant generated charge carriers into the charge transferring layer. The charge generating layer can be formed by mixing the pigment represented by the formula I with a proper binder, adding a charge transferring material as required and coating the mixture on a substrate. Since there is a limit in the capacity of the charge transferring layer to transfer charge carriers, the thickness of the layer can not be made larger than the necessary thickness. The preferred thickness is 8-20mum.

Abstract: PURPOSE: To effect switching or the like of a plurality of water supply control systems in a short time by providing a second control means to output a second signal changing rate opposite in polarity while a first control means controls a first water supply system based on the second signal changing rate. CONSTITUTION: A flow rate control signal uB to be applied to the second turbine drive pump pB is a changing rate integrated and a flow rate control signal uA is applied as sum of a signal obtained by integrating a feedback control signal of a rise in the water level of a boiler 20 associated with the starting of a turbine drive pump pB and a signal changing rate to the first turbine drive pump pA by the flow rate control signal uB. Discharge quantities of the first and second pumps pA and pB varies according to changes in the flow rate control signals uB and uA to keep the amount of water supplied to the boiler 20 constant. As a result, a deviation of the water level is almost constant and when the flow control signals uB and uA become equal, additional starting of the second turbine drive pump pB ends thereby shortening time required.
