Title: Film driving device
Inventor: NABA MASAHIRO
IPC: G03B19/18
Filed: 1978-12-22
Abstract: PURPOSE: To perform film feeding of low noise accurately and surely with a simple constitution by sending the drive signal synchronized to shutter rotation to the stepping motor which drives the film sprocket of a projector.  
     CONSTITUTION: When a shutter 1 rotates, a detector 2 rotates synchronously to operate an oscillator 3. A stepping motor 4 is operated by the electric signal obtained thereby, by which the sprocket wheel 5 of the output shaft is rotated. Further, the sprocket wheel 5 engages with the perforations 7 on the film 6, thereby moving the film 6. The engagement of the sprocket wheel 5 and perforations 7 does not accompany any strking sound and extremely smooth film driving is possible. In addition, this driving synchronizes with the shutter rotation and is accurate and sure. The stepping motor driving signal may be made to the simple constitution by the photo coupler.

IPC: H04Q9/00
Filed: 1988-06-28
Abstract: PURPOSE:To avoid the input of improper data to a plant monitor and to eliminate a temporary transmission error by providing a timer generating a pulse signal at a longer period than the transmission interval from a remote input section. CONSTITUTION:A timer 15 generates a pulse signal SC at a period Tt slightly longer than the data transfer period from a transmission section 5 to a reception section 7 and the pulse signal SC is outputted to an input control section 8. Furthermore, the timer 15 starts its operation when a timer start signal TS is applied from the input control section 8 and stops its operation when the timer stop signal TF is applied from the input control section 8. Thus, only when normal data are settled and the data is subject to DMA transfer, the data is inputted to a plant monitor. Moreover, if any data error is caused in the received data, the transmission error is avoided and when a reception data not including any error is obtained, since the received data is transferred to the plant monitor 9, the plant operation monitor of the plant monitor device is continued.

Abstract: PURPOSE:To save power consumption at standby by inserting a constant current source circuit to a connection path from a positive voltage source terminal to a control signal application section and inserting series circuit comprising other constant current source circuit, a logic signal application section and a control element to the connection path to a level shift section and using an output of the control signal application section to control a control element. CONSTITUTION:In applying a signal from terminals IN1-IN3 to a logic signal application section 1, each NPN transistor (TR) amplifies it and the result is compared with an output of a circuit 14 obtaining a reference voltage Vr. When the signal does not exceed the reference voltage Vr, a TR at the left of the control element 13 is controlled mainly by an output of a control signal application section 2 and the TR at the right side applies the tracking thereto. Thus, an output subjected to level shift or not by a level shift section 6 reaches a constant current source switching section 8, where normal switching is applied. When the signal fed to the logic signal application section exceeds the reference voltage Vr, the TR at the right side of the control element 13 is controlled mainly by the output of the control signal application section 2.

Filed: 1981-10-07
Abstract: PURPOSE:To shorten the focusing time and to make a sure focusing possible, by using an up/down counter to determine the driving quantity of a principal lens and performing the focusing in the system of coincidence between two images. CONSTITUTION:A measured distance for coincidence between two images which is detected by a distance detector 8 and a set distance are compared with each other in a comparator 9; and when the measured distance is shorter to make the output of the comparator high-level, an up/down counter 14 is set to the up- counting mode. This counter 14 counts clocks corresponding to the lens driving speed from an oscillator 11 in accordance with the measured distance passing through an A/D converter 13; and when the counted value reaches the set distance value, the output of a matrix circuit 15 is inverted to the low level. A high-level lens driving stop signal is generated through an inverter 17, and an AND gate 19 is closed through an inverter 18 to break the output of the comparator 9 which drives the lens. When the measured distance is longer than the set value, the similar operation is performed, and thus, hunting driving of the lens is prevented to perform a sure focusing in a short time.

Filed: 1986-07-07
Abstract: PURPOSE:To make it possible to form a piston pin from a ceramic, by providing a pin boss so as to allow a lubricating oil in a cylinder or a piston to flow toward a snap ring retaining groove. CONSTITUTION:In the operation of a piston 11, a lubricating oil scraped by an oil scraper ring 16b is allowed to flow from a ring groove 17b through an oil passage 18 passing through a pin boss 12 into a snap ring retaining groove 14.
