Title: Lubricating device for final reduction gear
Inventor: TERAOKA MASAO
IPC: F16H57/04
Filed: 1989-06-16
Abstract: PURPOSE:To make the degree of freedom for a mounting position as well as to enhance stillness and reliability by transmitting rotation of a drive pinion shaft to a flexible wire via a warm wheel and thereby driving a pump. CONSTITUTION:When a vehicle is in a forward movement, a worm wheel 34 rotated in an arrow direction through rotation of a warm 32 with rotation of a drive pinion shaft 14, thereby rotating a turning shaft 42 of a pump 38 in the arrow direction via a flexible wire 36. In brief, a one point A with a thread groove 40 is moving upward. With this turning shaft 42 rotated in the arrow direction, oil flows in direction of the thread groove going up, and an inner surface of a cylinder 44 comes to a working surface, and it functions as a viscous pump, pumping up the lubricating oil, thus it is fed to a specified part by way of a conductor 48. When the drive pinion shaft 14 is rotated in the backward direction of the vehicle, the oil flows to the downward of the thread groove 40, but since backward motion is usually in a short time limited and there is a rakeup of the lubricating oil by a ring gear 24 in addition, there is no oil break.

Title: Production of liquid crystal panel
Inventor: ONO YOSHIHIRO
IPC: G02F1/1337
Filed: 1992-06-12
Abstract: PURPOSE:To orient a liquid crystal by using an exposing process without executing rubbing by using a photosetting resin layer as an oriented film. CONSTITUTION:The photosetting resin layer 105 formed by coating the surface of a substrate 102 with the photosetting resin, then subjecting the resin to exposing and curing by providing various intensities of light in a stripe form is used as the oriented film. The photosetting resin layer 105 is exposed and cured by providing the various intensities of light in the stripe form and, therefore, internal stresses vary with the strongly exposed parts and the weakly exposed parts and force is generated between these parts to arrange the molecular chains of the photosetting resin toward the direction of the force. The liquid crystal molecules are oriented along the molecular chains. The photosetting degree varies with the various degrees of exposing. The volumetric change of the resin takes place and microscopic ruggedness arises in the parts where the volumetric change is large and the parts where the volumetric change is small as the photosetting progresses. This ruggedness contributes to the orientation of the liquid crystal.

Title: Semiconductor device
Inventor: KATSUBE MASAKI
IPC: H01L29/78
Filed: 1990-06-14
Abstract: PURPOSE:To relax electric field concentration and to improve breakdown strength of an MOSFET by changing a width of an offset low concentration layer between proximity to a drain diffusion layer and proximity to a source diffusion layer. CONSTITUTION:When a voltage of a gate electrode 6 is CV, electric force line 11 goes toward a direction of the gate electrode 6 from a drain diffusion layer 4 and does not increase or decrease on its way toward a source diffusion layer 3 and the gate electrode 6 from the drain diffusion layer 4. Meanwhile, breakdown occurs when electric field of a semiconductor constituting an MOSFET is a fixed value (breakdown electric field) or more. Since electric field is proportional to electric force line concentration and electric force line does not increase or decrease, electric field, that is, electric force line concentration is lowered only by increasing an area of a region therethrough electric force line passes. Accordingly, theta3 and theta4 are made vertical, theta1 and theta2 are made an acute angle at A at the gate electrode side wherein field concentration of an offset low concentration layer 7 is produced, a border line is provided with a part which is not vertical to a border line between a gate electrode and an offset low concentration layer part in an element region in an offset low concentration layer part. Thereby, an area of an offset low concentration layer in the part is increased to relax field concentration.

Abstract: PURPOSE: To prevent the lowering of the braking pressure due to a transient deceleration change of the wheel, by decreasing or increasing the braking pressure according to the deceleration of the wheel when a slip coefficient has become above a prescribed value.  
     CONSTITUTION: A pulse signal from a wheel velocity sensor 1 is converted at a wheel velocity arithmetic unit 2 into a wheel velocity signal V, which is then differentiated at an acceleration and deceleration arithmetic unit 3 into a signal proportional to the acceleration or deceleration of the wheel. The output of the arithmetic unit 3 is subtracted at a subtractor 4 by a certain value corresponding to a prescribed acceleration. A vehicle velocity arithmetic unit 5 receives the signal V and a signal from a vehicle deceleration detector 51, and when the decreasing rate of the signal V is above a prescribed value the unit 5 outputs a vehicle velocity signal E that decreases at a decreasing rate according to the vehicle deceleration. The signal E is inputted via an attenuator 6 into a comparator 7, and when the comparator 7 outputs an H level, an electric current proportional to the output of the subtractor 4 transmitted through a switch 8 is applied by an amplifier 9 to a pressure controlling valve L10.

Abstract: PURPOSE:To improve transfer efficiency and to prevent thickening of lines and generation of scattering traces in a corona transfer device which discharges corona from the back of a transfer material and transfers toner images thereon by acting magnetic fields from the outside. CONSTITUTION:Magnetic fields 7 are applied to a corona transfer part by a magnet 6. Since developing toner 2 having magnetism is exposed to the magnetic fields 7 and is attracted to a transfer material 3 by receiving the gradient forces of the magnetic fields, the generation of the effect of replacing the upper layers 2a with the lower layers 2b is prevented. More specifically, if one toner particle of the toner 2 has magnetization mu, said particle receives the force of F=mugradH, and since this gradH directs toward the transfer material, the effect of replacing the layers is prevented. Thus the transfer efficiency is improved and the generation of lines thickening of and scattering traces is prevented.
