Title: Valve timing adjusting device for internal combustion engine
Inventor: TAKENAKA AKIHIKO
IPC: F01L1/34
Filed: 1992-09-10
Abstract: PURPOSE:To carry out a precise control by preventing air from flowing into a hydraulic chamber in a valve timing adjusting device so as to enhance the responsiveness of the valve timing adjusting device during the operation. CONSTITUTION:The timings of intake and exhaust valves in an internal combustion engine can be changed by means of an intermediate member having an helical tooth part. A hydraulic piston for driving the intermediate member is controlled by a control valve for changing over hydraulic pressure into a hydraulic chamber. Discharge ports 92, 98 are communicated with an oil discharge preventing passage 102 which extends by way of a position above the hydraulic chamber. With this arrangement, during operation or resting, oil leakage from the hydraulic chamber can be prevented, and accordingly, the hydraulic chamber is always held in an oil full condition. Thus, when the valve timing adjusting device is driven, the rotational phase difference between the intake and exhaust valves can be precisely controlled to a desired phase difference with high responsiveness by means of the intermediate member and the cam shaft under the hydraulic pressure control of the hydraulic piston.

Title: Electrooptic device
Inventor: KOBAYASHI HIDEKAZU
IPC: G02F1/1337
Filed: 1986-10-13
Abstract: PURPOSE:To permit creation of nearly perfect bistable states by rubbing the oriented films on substrates for sandwiching a liquid crystal with a fabric in two directions and equalizing the initial orientation stability and the next orientation stability. CONSTITUTION:Liquid crystal molecules line up in the directions where the oriented films of the substrates for sandwiching the liquid crystal are rubbed afterward if the oriented films are rubbed in the two directions with the fabric; therefore, the liquid crystal molecules face the direction where the films are rubbed first when an electric field is impressed thereto from above to below. Both the molecules stabilize at about the same degree at this point of the time. The oriented film 5, is thereupon, formed on the lower substrate side and is rubbed 4 times in one direction with a bleached cotton cloth, then rubbed once after the direction is shifted 30 deg. clockwise from said rubbing direction by taking the direction of bipoles and the direction of the spontaneous polarization of the liquid crystal into consideration. The bistable states in which the two states are stable at about the same degree are then created by assembling such substrates.
