The present invention discloses a whipstock assembly (100) for use in forming a lateral borehole from a parent wellbore. The whipstock assembly comprises a body (122) and a deflection member 120) above the body. The deflection member includes a concave portion (111) for deflecting a milling bit during a milling operation. Disposed on a perforation plate (110) portion of the concave portion is a raised surface feature (116). The raised surface supports a milling bit above the perforation plate portion during a milling operation. This, in turn, substantially prevents frictional contact between the milling bits and the perforation plate portion during a milling operation. The present invention also provides a novel method for manufacturing a whipstock in which a cavity portion is formed behind the perforation plate by milling out the backside of the deflection member and then joining a second back cover member to the whipstock body to complete the assembly.

The pressure in a cylinder of a combustion engine is determined on the basis of vibrations in the engine which are generated during movement of the piston. A vibration signal (S) from a vibration sensor situated on a cylinder is filtered in the region about the piston top dead center position, at the transition from compression to expansion, in a special filter in which a half Hanning filter acts upon the vibration signal before and an exponential filter acts upon the vibration signal after the piston top dead center position. The filtered signal (U) is thereafter converted to a pressure signal (P) on the basis of an established relationship between vibration and pressure. The half Hanning filter has a significantly shorter time window (TH) than the exponential filter (TE). The filter cleans the vibration signal in an advantageous manner and makes more reliable pressure determination possible.

A grip of a writing material is formed by providing a plurality of flange-like on a surface of a middle shaft portion of a shaft cylinder and in parallel across an axis of the shaft cylinder, the plurality of flange-like projections projecting in a radial direction of the shaft cylinder, and integrally covering the flange-like projections with a cylindrical cover in a closable manner so that spaces are formed inside the cover. When a user grips the grip of the writing material with his or her fingers, the pressure allows the cover to be borne by the adjacent flange-like projections, while moving air inside the spaces to deform the cover. The deformation absorbs the pressure from the fingers. Further, the adjacent flange-like projections limits the deformation of the cover, thus enabling the initial positional relationship of the fingers to be maintained. The user can thus use the writing material for a long time.
