Title: Guide bearing
Inventor: TOMIOKA SHIYUNZOU
IPC: F16C17/03
Filed: 1978-09-22
Abstract: PURPOSE: To supply a sufficient quantity of oil in between pads, maintain a sufficient level of oil at the inlet parts of the pads and prevent the cut-off of oil film and stirring of the oil.  
     CONSTITUTION: When a vertical rotary electric machine is started, the oil film is produced on the supporting surfaces of bearing segments 2 depending on the revolution speed of the machine and at least part of each pad is located in the oil in a vessel. Since an appropriate quantity of the lubricating oil is supplied to the cooling and lubricating pads 21 by a hydraulic pump, the lubricating oil is ejected from the rear ends of the pads 21 and introduced into the inlet ports of the bearing segments 2 and the oil film is produced on their total supporting surfaces even if the level of the oil falls due to the increase in the revolution speed of the machine. The oil film is prevented from being cut off when a heavy load is applied to the bearing segments.

Title: Camera and its operating method
Inventor: SHINOHARA MITSURU
IPC: G03B17/02
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To effectively utilize space, to make a camera compact and to simplify its constitution by providing a switching means obtained by integrating an autofocusing start switching means and a preset reproducing switching means into one. SOLUTION: When a combined switch SW3 is turned on, autofocusing(AF) is performed in the same manner as when a conventional range-finding start switch is turned on. The switch SW3 is turned on/off, and then it is turned on/off once more. By performing operation for turning on/off the switch SW3 for the second time in a previously set time, the switch SW3 functions as a focus preset reproducing switch. Since one switch SW3 has the function of the AF start switch (or a focus lock switch) and the function of the focus preset reproducing switch in such a way, the space is effectively utilized, the camera is made compact and the constitution is simplified.

Abstract: PURPOSE:To prevent conductor patterns from being short-circuited by a solder by a method wherein a plurality of conductor patterns are arranged in such a way that their end sides in parts to be soldered are formed to have respectively protruding and recessed shapes and that their protruding parts and their recessed parts are faced with each other alternately at their adjacent conductor patterns. CONSTITUTION:Conductor patterns 4a, 4b are formed in such a way that their end sides in parts to be soldered are to be protruding and recessed shapes; protruding parts and recessed parts at the adjacent conductor patterns 4a, 4b are faced with each other alternately. When the width in one part of connecting parts at one conductor pattern 4a is made larger than the width of a terminal 1a, the width can be made narrow in parts of the conductor pattern connected to it. Consequently, when the protruding parts of the conductor pattern 4a are made to correspond to the recessed parts of the adjacent conductor pattern 4b and the recessed parts of the conductor pattern 4b are made to correspond to the protruding parts of the adjacent conductor pattern 4b, the interval in individual parts of the conductor patterns 4a, 4b can be made larger than the interval of conductor patterns whose sides have been formed in a linear shape.

Abstract: PURPOSE: To increase the speed of fixing without increasing electric power consumption by providing a platelike exothermic member in a position where it contacts transfer paper and guides the carry-in of the transfer paper, on the transfer paper carry-in side of a heat fixing roller.  
     CONSTITUTION: The toner images on an electric charge holding body 1 is once transferred on a beltlike intermediate transfer body 10, and are transferred and fixed onto transfer paper P by the heat and pressing effect of a heat roller 7 and a pressure roller 8. A platelike exothermic member 11 preheats the tranfer paper P carried into a pressure transfer fixing system formed by the roller 7 and the roller 8 by contacting the same and also serves to guide its carry-in. It is a good practice to constitute the member 11 in such a way as to heat the roller 8 as well. The similar effect is also obtained by disposing the member 11 in the transfer paper carry-in position of an ordinary heating roller pair using no intermediate transfer bodies.

Title: Optical scanning device and optical lens
Inventor: ICHIKAWA JUNICHI
IPC: G02B13/00
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To easily realize an over-field optical system and to avoid the increase of a side lobe by forming a wave surface for correcting aberration at a second optical system on which one part of luminous flux deflected by a rotary polygon mirror at a first optical system is made incident. SOLUTION: By the first optical system on which all of the luminous flux emitted from a light source are made incident, the wave surface for correcting the aberration at the second optical system on which one part of the luminous flux deflected by one reflection surface of the rotary polygon mirror is made incident is formed. That means, the deviation OPD of the wave surface of a conventional collimator lens from a flat surface is zero and flat but the emitted wave surface of the lens is deviated more from the flat surface as it is distant from an optical axis.  Since the wave surface used when the scanning center COS of a surface to be scanned is irradiated is symmetric with respect to the optical axis and the deviation from the flat surface is small, the difference of the shape of the wave surface between the collimator lens is small when the scanning center is irradiated and a beam profile is not changed. Besides, the emitted wave surface used when a scanning end SOS is irradiated is asymmetric with respect to the optical axis and the wave surface on one side is largely deviated from the flat surface.
