Title: Thermal expansion compensator for boring main shaft device of machine tool
Inventor: KOIKE ISAMU
IPC: B23B19/02
Filed: 1986-06-19
Abstract: PURPOSE:To improve the axial working precision of a machine tool by mounting a change-over controller which can freely release a tool's main shaft reciprocating means when pressure fluid is supplied to a clamp member which fastens the main shaft of a tool. CONSTITUTION:Pressure oil is supplied from a pressure oil supply unit to a pressure chamber 10 by a change-over controller 28 to operated a clamp shoe 9 so that a tool's main shaft 4 and a boring main shaft 2 are stuck to each other unitedly. Simultaneously, the change-over controller 28 releases the driving system of a servo motor 24 via a NC unit 26, whereby enabling the servo motor 24 of being moved freely by the external force. When under such state the tool's main shaft 4 expand thermally, said shaft 4 extends at the rear part thereof to press a nut 19 to turn a ball screw 18. On the other hand, said shaft 4 extends at the front part thereof to proceed the rear end of the tool's main shaft. When the clamping force applied to both the tool's main shaft 4 and the boring main shaft 2 is released temporarily and the subsequent work is to be performed, the origin compensating activity is executed using an automatic centering unit.

Title: Transparent coated molding and manufacture thereof
Inventor: HIGUCHI TOSHIHIKO
IPC: B32B27/00
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To improve the adhesion with a base material, the wear resistance, transparency and antimarring properties by forming a cured product layer of a coated composition containing a polyfunctional compound and a polysilazane containing fluorine on the surface of a transparent synthetic resin base material. SOLUTION: A transparent cured product layer is a cured product layer of a polyfunctional compound having two or more polymerizable functional groups which are curable by active energy radiation and a coated composition having a polysilazane containing fluorine. Formation of the cured product layer as described imparts outstanding antimarring properties to the moldings without impairing the outstanding adhesion with a base material. Further, the antimarring properties are further enhanced by using the polysilazane containing fluorine, resulting in the upgrading of water repellency, oil repellency, mold release characteristics or the like as well as the increase of productivity.  Besides, it is possible to prevent cracks from being generated in the cured product layer by bending the moldings while the polysilazane containing fluorine is uncured or partially cured, and thus manufacture the transparent coated moldings which are processed by bending and show superb surface characteristics.

Title: Decoding method for digital signal
Inventor: MATSUFUJI KATSUAKI
IPC: H03M7/30
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To provide decoding method for a digital signal by which the digital signal is decoded with high precision without causing much increase in arithmetic amount. SOLUTION: Spectrum data formed as units are received, and a maximum absolute value of a scale factor is obtained (S1, S2). Then whether a scale amount is to be fixed or made variable is discriminated by using a threshold, based on the obtained maximum absolute value (S3, S5). Then IMDCT processing is applied to the data based on the result of discrimination (S4, S6, S7), and audio data are outputted (S8). Since scaling method is discriminated depending on the spectrum data, decoding with high accuracy is attained without causing much increase in an arithmetic amount.

Title: Device to support residual pile of printing leaf papers at automatic replacement of pile, and method to operate this device
Inventor: HERUMUUTO EMURITSUHI
IPC: B65H1/26
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To minimize sinking of a residual pile in pulling out fork bars by forming a cross section of the fork bars so as to have the sufficiently large resistance moment to support the residual pipe in a first rotational position and to have a slight vertical directional dimension in a second rotational position. SOLUTION: Fork bars 1 have the maximum resistance moment to support a residual pile 3 in a first rotational position A. Since sheets are taken out in order from above the residual pile 3, a pile height of the residual pile 3 reduces during pile change. When a new pile 8 is approached to the fork bars 1 from below, weight of the residual pile 3 is immediately placed on a pile raising device via the new pile 8 and a pile support pallet under it. Thus, the fork bars 1 are reduced in a load, and can rotate to a rotational position B changed by 90 deg. with the longitudinal axis 2 as the center without danger of buckling, and the pile raising device rises at the same time.

Abstract: PURPOSE:To eliminate variation in film quality caused by temperature difference at vapor growth by carrying out vapor growth while alternating positions of inner and outer wafers. CONSTITUTION:A set of wafers consists of an inner wafer and an outer wafer inside a susceptor 1. A wafer 4 is mounted on a disk 3 which rotates freely against the susceptor, and heated by a heater 5. Here in the disk 3, a gear is engaged with a fixing axis 2 which does not rotate to the inside of a susceptor rotating axis. Therefore, the disk 3 rotates by itself as the susceptor rotates, and the relative positions of the inner wafer and the outer wafer alternate each other. Variation in film quality caused by temperature difference at vapor growth can be thereby eliminated and a uniform film can be obtained.
