Title: Film and its feeding controller
Inventor: YOSHIDA YUTAKA
IPC: G03B17/00
Filed: 1991-06-17
Abstract: PURPOSE:To stop a film at the last frame without exerting forcible tensile force on the film, to stop the rewinding action of the film in a state where a leader part is left, and to accurately detect the position of the frame in spite of simple constitution. CONSTITUTION:By respectively and consecutively forming plural perforations 6 near the leader part 5 and the final frame 8 of the film 1, a perforation group 6a for detecting a leader part and a perforation group 6b for detecting the trailing edge of the film are formed. The perforation 6 for positioning a frame is formed corresponding to each position of the photographic frame 7 so that the number and the arrangement of the perforation 6 are different from those of the perforation groups 6a and 6b. A film feeding controller detects the perforation groups 6a and 6b and the perforation 6 respectively and controls feeding, stopping and rewinding the film 1.

Title: Highly accurate ac/dc converter
Inventor: YONEZAKI GENTA
IPC: G01R19/02
Filed: 1992-06-05
Abstract: PURPOSE:To eliminate the difference between AC and DC currents by coating an inner conductor with an outer conductor to produce a coaxial cable, employing a resistor at a part of the inner conductor, and disposing a temperature sensor in or on the outer periphery of the outer conductor at a position where temperature rises due to AC and DC current supplies are identical. CONSTITUTION:A hollow tubular inner conductor 1 is provided in an outer conductor 2 and a resistor material is deposited partially on the surface of the inner conductor 1 thus forming a resistor 3 of length 2L with the opposite ends thereof being located at positions -L and +L. A position spaced apart by a distance (d) from the center (o) of the resistor 3 is then determined and a temperature sensor 4 is arranged along the inner peripheral surface of a conductor 2 corresponding with the position thus determined. The position represents a point where temperature rises due to AC and DC current supplies to the resistor 3 are identical and the distance (d) is determined according to a formula; d=-CL<2>/4, where C is Thomson coefficient. When the temperature sensor 4 is disposed at a point separated by a distance (d) from the center (o) of the resistor 3, an AC/DC converter having zero AC/DC difference can be formed.

Title: Oil lubricated bearing
Inventor: YOSHIDA YASUO
IPC: F16C37/00
Filed: 1990-06-27
Abstract: PURPOSE:To reduce the extent of bearing loss in an oil lubricated bearing equipped with a means for cooling lubricating oil, by controlling the cooling capacity of this cooling means, and making a temperature of lubricating oil higher within the allowable limit of temperature in a bearing part, thereby lowering a degree of viscosity in the lubricating oil. CONSTITUTION:A temperature regulator 52 has a specified temperature reference value, and a temperature detector 51 detects each temperature of a thrust bearing part 2 and a guide bearing part 8. When cooling air passing through an oil cooler 18 is low in temperature and thereby a detected temperature is lower than the temperature reference value, a control signal is issued to a pilot motor 54 from the temperature regulator 52 so as to make the opening of a flow control valve 53 smaller. If so, an amount of lubricating oil 13 being circulated to the oil cooler 18 by means of a self-pump hole 5 is reduced to some extent, and thereby a cooling capacity of the oil cooler 18 becomes lowered. Contrariwise, when temperature in the cooling air is higher, reverse operation to the abovementioned takes place, thus the cooling capacity increases. As mentioned above, since the cooling capacity of the oil cooler 18 is controlled, the lubricating oil 13 will not come to low temperature so unnecessarily, thus oil viscosity is kept low as required.

Title: Signal input circuit
Inventor: MUKAI MASAAKI
IPC: H01L27/08
Filed: 1986-07-21
Abstract: PURPOSE:To obtain a signal input circuit having high degree of freedom which can be used to be changed into either pull-up or pull down input circuit, by controlling on/off states of both P and N channel transistors which form input circuits through a definite controlling signal. CONSTITUTION:When a controlling signal coming from a controlling circuit 5 is on a H level, an N channel transistor 3 becomes on a ON state, and a P channel transistor 2 is held on a OFF state, so that a terminal 101 is operated as a pull-down input terminal. Namely when an external signal inputted through the terminal 101 is on an L level, potentials on both terminals of a resistor 1 become nearly identical to each other, and therefore current hardly flows across it. Thus, the current flows into a negative source via the resistor 1 from the terminal 101 only when the external signal is on the H level. When the controlling signal coming from the controlling circuit 5 is inversely on the L level, the P channel transistor 2 becomes on the ON state, and the N channel transistor 3 becomes on the OFF state, so that the terminal 101 is operated as a pull-up input terminal.

Filed: 1990-06-30
Abstract: PURPOSE:To avoid useless changing action at the time of rotation, and obtain changing characteristics corresponding to rotation conditions by receiving a signal from a vehicle speed comparing means, and changing the characteristics of speed change control based on a result of comparison of the maximum vehicle speed with an actual vehicle speed. CONSTITUTION:A control unit 10 performs a control for changing the speed changing characteristics while a vehicle is rotating. Generally, a predetermined relation exists between a steering speed and the maximum steeling angle. By measuring an initial steering angle, therefore, the maximum steering angle in its curving passage can be estimated. When the maximum steering angle is known, a radius of curvature of the curving passage can be estimated, and when the radius of curvature is known, the maximum vehicle speed which the vehicle can run in rotation can be estimated. The estimated maximum vehicle speed is compared with an actual vehicle speed, and when the actual vehicle speed is larger than the maximum vehicle speed, changing action of an automatic transmission 4 is limited, under consideration that there is a large possibility of control being performed after that.
