Filed: 1995-02-13
Abstract: PURPOSE: To provide a plastic-made hollow molded product which is thick in wall, long, free from residual stress, and suitable as a structural material of construction or the like in a park or the like. CONSTITUTION: A false wood like hollow molded body of 10mm-50mm wall thickness (t) and at least 1m length (l) which is made of a waste plastic as a raw material, is used by filling a core material 2 in a hollow part 3. Since it is sufficiently cooled when molding, free from residual stress, and a vacant space of a specific width is provided between an inner wall surface of the hollow part 3 of the hollow molded body 1 and an outer wall surface of the core material, any crack is not generated even by expansion and contraction owing to fluctuation in atmospheric temperature.

Filed: 1988-02-29
Abstract: PURPOSE:To read a position with high accuracy without performing mechanical fine adjustment, by solving simultaneous equations formed by a plurality of calculation formulae when position reading data is converted to absolute position data and determining the coefficients of the calculation formulae. CONSTITUTION:In assembling an encoder apparatus, an imaging element 11 is arranged with respect to a scale plate 10 within a rough accuracy range permitted for said element 11. In this state, the imaging signal due to the imaging element 11 is inputted to a detection circuit 14 and the center position coordinates of a pattern are read but, at that time, the center coordinates Xk, Yk of some pixels of the pattern and the numerical value data Ak of a gray code are sent to an external computer 16 to form simultaneous equations which are, in turn, solved to calculate a coefficient for converting reading data to absolute position coordinates and absolute position data is calculated by a coordinates converter circuit 15. Therefore, absolute position data is read with high accuracy without performing mechanical fine adjustment wherein much labor is required.

Title: Exclusive control method
Inventor: HAYAMIZU HARUO
IPC: G06F9/52
Filed: 1988-02-29
Abstract: PURPOSE:To lighten the burden of a central processing unit concerned with exclusive control by reporting busy to a reference registration request when an object page is already registered and transmitting the interruption of busy-to- free to the central processing unit which reports the busy to the reference registration request when the registration of the page is canceled.

Title: Control rod driving apparatus
Inventor: ASANO HIROMITSU
IPC: G21C7/12
Filed: 1978-04-24
Abstract: PURPOSE: To accomplish secure retention of a drive shaft by means of a magnetic rotor fixed to the drive shaft in such a manner as to be confined by a permanent magnet while it fails to be driven.  
     CONSTITUTION: A motor or a drive shaft of the control rod driving apparatus is provided with a control rod position retaining device 10, which comprises a rotor 12 and a stator 11 The rotor 12 has convex poles 12A to 12D arranged on the circumference at an equi-space, where the position of the rotator is determined by the movement distance of the control rod 1 and the conversion ratio of a converter 2. On the other hand, the stator having convex poles (all permanent magnets) equal in polarity, number and positional relationship to the rotor is arranged on the internal circumference of a cylinder with the drive shaft 3 as center axis and wound with a coil. When the control rod fails to be driven, the pole of the rotor 12 is attracted toward the pole of the stator as opposed thereto by magnetic force. This prevents invertion of the motor shaft 4 due to own weight of the control rod. With current flowing through the coil 13, the magnetic force of the permanent magnet is cancelled whereby the rotor 12 is released from the stator 11.

Filed: 1988-03-03
Abstract: PURPOSE:To simplify the circuit constitution by constituting an emitter coupling circuit by a couple of photo transistors(TRs) and converting a differential output of the emitter coupling circuit into a logic signal by a comparator. CONSTITUTION:Optical fibers 1, 2 are coupled optically at a base region of the photo TRs 3, 4 whose emitters are connected together.
