Title: Bearing device in rotary electric machine
Inventor: IKEDA KAZUO
IPC: F16N31/00
Filed: 1977-11-16
Abstract: PURPOSE: To provide the subject device wherein the exhaust side over the full surface of the inner part section of an exhaust hole is rendered wider than the inner peripheral side, thereby to prevent the adherence of grease.  
     CONSTITUTION: An inner surface 17 in the axial direction and an inner surface 18 in the radial direction forming a grease exhaust port 16 are inclined at a predetermined angle with respect to the vertical direction so that the exhaust port at the outer peripheral part is made wider than opening part of the inner peripheral surface. By forming the exhaust port 16 as described above, grease drops smoothly downward by its own weight. Further, since the grease 13 is easily exhausted, there is reducecd the leakage of oil out of a gap G between a rotor shaft 1 and the inner peripheral end surface of an inner bearing cover 4 and a gap 14 between a cover 9 and a oil thrower 11, and therefore the periphery thereof is not stained, the maintenance of the machine is easy, and it serves for the prevention of deterioration of insulation of the rotary electric machine.

Filed: 1990-05-25
Abstract: PURPOSE:To obtain an image without having color slippage by setting the reading action of an original or the timing of the rotational action of a photosensitive body corresponding to the refractive direction or refractive quantity of light in the transverse direction of a filter. CONSTITUTION:A scanning mirror 5 is driven along an original platen 2 together with a reflected plate 4 and a light source 3, and on a process that a mirror 6 is driven at the half speed of that of the mirror 5, an original image is read out. The photosensitive body 10 has the application of a charge from an electrifier 11 and electrified. On the electrified part, a read image is color-resolved by any filters of a color resolving filter device 21 and formed as an electrostatic latent image. The electrostatic latent image is developed by any developing units of a developing part 13. Then, on the process that sheets fed from paper feeding cassettes 14 and 15 are held and rotated by a transfer drum 22, a developed image on the photosensitive body 10 is transferred by a transfer part 18. Thus, the image without having the color slippage is obtained.

Title: Information signal reproducer
Inventor: TAKAYAMA NOBUTOSHI
IPC: G11B15/467
Filed: 1984-07-02
Abstract: PURPOSE:To switch a medium driving speed with high reliability by detecting that the medium driving speed is different from that of a record mode for each variance cycle of a tracking error signal, then switching the medium driving speed when said detected fact continues in the prescribed frequency. CONSTITUTION:A high frequency component such as noise, etc. is deleted out of an ATF (tracking error) signal 101 through an LPF102. Then the signal 101 is compared with the prescribed voltage Vth by a comparator 103. The capstan output frequency FG which is supplied to a terminal 111 for a period during which the comparison output is kept at L is counted by a counter 104. A monostable multivibrator 106 outputs a pulse synchronously with the rise of the output signal of the comparator 103. A counter 108 counts the output of an AND gate 107, and an FF110 is inverted with the rise of the output of the counter 108. A terminal 112 outputs a signal to give an indication to a system control circuit for reproduction of a standard time mode or a long time mode. The driving speed is switched when the driving speed is different from that of a record mode and this fact is detected continuously in the prescribed frequency. This improves the reliability for switch of the medium driving speed.

Title: Ptc composition
Inventor: TAKAHATA OKIKUNI
IPC: H05B3/14
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To lower a resistance value at room temperature, hinder ignition when an electric current flows, suppress resistance rise in each high temperature operation, and enable arbitrary setting of operating temperature, by dispersing, in a polymer constituent, not a pure metal but metallic compound powder having resistivity of a specific value or less and grain size in a specific range. SOLUTION: This PTC composition is a composite composition mainly composed of a polymer constituent and a conductive powder constituent and having electrical resistance of a positive temperature characteristic, and metallic carbide powder having electric resisitivity of 10<-3> Ω.cm or less and the grain size of 0.01 to 100 μm is dispersed as the conductive powder constituent. By this, the room temperature reisitivity can be lowered without causing the metallic carbide powder to gather in an amorphous region of a polymer matrix or without causing aggregation of the metallic carbide powder itself.  Accordingly, when the amount of the conductive powder dispersed is increased, partial conducting paths are not formed, and because of its grain size of 100 μm or less, the powder itself does not act in the same way as an aggregate of powder of smaller grain size, therefore no ignition is generated if an electric current is passed therethrough. A high polymer composition having the metallic carbide composition dispersed therein has room temperature resistivity not rising in the event of repeated operation.

Title: Double bypass engine
Inventor: NEMOTO ISAMU
IPC: F02K3/06
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To improve a fuel consumption rate for reducing the emission quantity of NOx by partially extracting a working gass from the output of a high pressure turbine, and bypassing a low pressure turbine to lead an extracted gass into a backward exhaust, in a low bypass ratio turbo-fan serving as a propulsion engine for a supersonic transport airplane. SOLUTION: The outlet of the high pressure turbine HPT of a double bypass engine is connected to a core exhaust duct D, and an extraction valve V is provided at the inlet of an extraction flow path P opened toward the inside of the exhaust duct D. The extraction valve V is opened during supersonic cruising to carry out extraction through the HPT outlet, and a low pressure turbine LPT is bypassed to make the flow rate of HPT working gass more than the flow rate of LPT working gass. Thus the work of a high pressure system is increased without decreasing the work of low pressure system, and moreover the number of compressor revolutions is increased to increase the flow quantity of compressor for decreasing a bypass ratio. On the other hand, the extraction valve V is closed during low speed flight to make the flow quantity of each turbine the same.
