Patent JP-S6449843-A (JP)
Title: Ventilating duct
Inventor: NAKAMURA SHIROSHI
IPC: E04B1/74
Filed: 1987-08-18
Abstract: PURPOSE:To disperse air uniformly when the air passing through the inside penetrates into the outside by a method wherein fibrous material is wound round in pipe shape to form a core and its inner surface and outer surface are covered by permeable covering material. CONSTITUTION:A core 1 is formed in such a way that one or more than one kinds of fibrous material such as glass fiber, plastic fiber, mineral fiber, metal fiber, etc., are wound round in pipe shape such as ring shape, etc., in its cross section and air blasting through the inner space alpha and ventilation penetrating through the openings in the fibrous material of the core 1 are carried out. The core 1 has a function that air moving in the inner space alpha is evolved into the outside by the pressure and diffusion of the air and when the air is evolved, the air is diffused in the core 1 by porosities formed by the interwinement of the fibrous material and the air is evolved uniformly into the outside. Sheet- shaped covering materials 2, 3 covering the inner and outer surfaces of the core 1 are used to obtain the form-holding property of the core 1 and also used to avoid providing an unpleasant feeling caused by touching of or sticking to hands and clothes of the fibrous material as the raw material of the core 1 at the time of assembly.

Filed: 1988-08-18
Abstract: PURPOSE:To measure the rotational speed of a code plate up to a high rotational speed without providing a high order high-pass filter by subtracting the output of a low-pass filter from the output of an adder-subtractor circuit. CONSTITUTION:In an encoder constituted so that two phase signals changing in their phases differentially corresponding to the angle of rotation of a code plate 1 and the phase change quantities in the phase signals are measured to calculate the angle of rotation of the code plate 1, a low-pass filter 22 extracting the signal corresponding to the variation of the DC component contained in the output of an adder-subtractor circuit from the operation signal in the adder- subtractor circuit is added and the output of the low-pass filter 22 is subtracted from the output of the adder-subtractor circuit. By this method, the signal corresponding to the variation of the DC component contained in the output of the adder-subtractor circuit can be extracted. Therefore, by subtracting said output from the output of the adder-subtractor circuit, the variation of the DC component accompanied by the rotation of the code plate 1 is preliminarily removed to make it possible to measure the rotational speed of the code plate 1 up to a high rotational speed without using a high order high-pass filter.

Title: Multiplying circuit
Inventor: OSADA ATSUSHI
IPC: G06F7/52
Filed: 1986-09-02
Abstract: PURPOSE:To make the error of a product into the irregular error which does not have a correlation with an input signal without generating the error of the product only in one direction by providing a dither generating means to add a noise to the multiplying means of two digital signals. CONSTITUTION:A multiplying circuit outputs higher orders P2-P15 only with the number of the effective digits of the product of two inputs X0-X7 of 8 bits as 14 bits. For this reason, a circuit to obtain lower order 2 bits of the product not outputted is omitted. Consequently, since the carry is not executed at the digit of the P2 of the product, a pseudo irregular noise generating circuit 5 is inserted into an input 43 of all adders 4. Thus, the error in the product can be made into the irregular error.
