Title: Rotational position detector for round billet
Inventor: NAKAJI SHIGERU
IPC: G01B21/22
Filed: 1987-03-04
Abstract: PURPOSE:To detect the circumferential length and circumferential position of a round billet accurately, by providing a device for detecting a rotational position thereof and a detection plate and the like to detect rotation and rotational position of the detection plate. CONSTITUTION:This apparatus is provided with a rotation detector 3 in which a detection plat 2 abutting a round billet K is mounted securely at the tip of an input shaft and a detection mechanism A which has a longitudinally driven cylinder 9 to press the detection plate 2 on the round billet K. A centering mechanism B is provided to vertically and horizontally move the mechanism A adapted to position the detection plate 2 facing the center of the end face of the round billet K and a universal mechanism C to hold the mechanism A in such a manner as to free to be displaced vertically and horizontally. With such an arrangement, the detection plate 2 is mounted under pressure on the end face of the round billet K intended to detect rotation without direct sliding thereby enabling the extracting of rotation of the round billet K accurately and correctly. Thus, even when caused between a part for rotating the round billet K and the round billet K itself, any trouble such as slippage in no way disturbs the operation of detecting rotation of the round billet K.

Abstract: PURPOSE:To attain the transformation into an LSI with the proper performance, the proper number of pins, a proper gate area, the proper power, etc., set in accordance with the performance of a processor by using plural memory control parts in response to the data width of a system. CONSTITUTION:A memory control part 11 corresponding to the data width of a system receives an interface address signal 100, an interface address data signal 200, and an interface memory control signal 300. Then the part 11 positions a bank with use of a position signal 701 and decodes an interface address signal 101 to produce a memory control signal 501 with an action applied to a single bank. Thus the part 11 performs the writing/reading operations to the corresponding memory part 21. The part 11 waits for its turn against to other banks and produces the signal 501 with actions applied to plural banks. The memory control parts 12 and 13 have the same operations as the part 11. Thus a storage can work in accordance with the performance of a processor with use of plural memory control parts which are transformed into an LSI with the proper performance, the proper number of pins, a proper gate scale, the proper power, etc.

Title: Engine mount
Inventor: ARUNO HAMEKAASU
IPC: F16F13/00
Filed: 1990-03-01
Abstract: PURPOSE: To damp vibration excited on the road surface and isolate vibration excited by an engine by compensating a volume increase of a liquid in a working chamber due to heating of an engine through compensating holes. CONSTITUTION: This engine mount includes two working chambers 1 and further a compensating chamber 3 which receives an additional liquid volume with non-pressure and is connected to the working chambers through compensating holes 5. In the case of using the engine mount in a sound-tight capsuled automobile engine room, the temperature necessarily becomes about 140 deg.C due to heating. Accordingly, though the liquid volume in the working chambers 1 is increased, such volume increase can be compensated through the compensating holes 5. Thus, the internal pressure as the design base is kept and there is no problem in respect of vibro-isolation and in respect of damping effect.  As the fluid resistance of the compensating holes 5 is very large, even if the vibration is transmitted to the working chambers 1 to cause a change in pressure, the liquid component is kept from being relatively displaced in the compensating holes to damage a function by the vibration.

Title: Formation of multilayered film
Inventor: ODOHIRA TOSHIHIKO
IPC: C23C14/14
Filed: 1987-03-06
Abstract: PURPOSE:To form a multilayered film excellent in adhesion and abrasion resistance by coating a Cr film on a substrate with ion plating and thereafter coating a TiN film while impressing bias voltage on the substrate. CONSTITUTION:The inside of a vacuum vessel 1 is evacuated and exhausted through an exhaust hole 2. Then Cr for coating material 4 incorporated in a crucible 3 is heated and evaporated with electron beams 6 projected from a plasma gun 5 to ionize it and deposited on the surface of a substrate 8 heated with a heater 7, then a Cr film is coated as an undercoat. Thereafter the material 4 is replaced with Ti and similarly heated and evaporated to ionize it and also N2 is fed as reactive gas through an introduction port 9. Thereby a TiN film is formed as a topcoat on the substrate 8. In the above-mentioned method, in the case of coating the Cr film, bias voltage is not impressed on the substrate 8 and in the case of coating the TiN film, bias voltage is impressed thereon. Thereby a multilayered film is stably obtained by forming the Cr film with high hardness and forming the TiN film with high adhesive force on the other hand.
