Title: Bearing made from synthetic resin
Inventor: KASHIMA SHIZUO
IPC: F16C19/00
Filed: 1986-09-29
Abstract: PURPOSE:To make a bearing usable under the state without lubricant by making inner, outer and retaining races from synthetic resin, rotatably inserting the retaining race into the inner/outer races, and forming a fitting hole for holding a ball in such a way as having a slightly greater diameter than that of the ball. CONSTITUTION:An outer race 5 is fitted around an inner race 1. And balls 8 are pressingly inserted, at the same interval, into a space between a streak groove 3 and a streak recess portion 7 of respective races 1, 5. Then, a retaining race 9 is inserted into a space between both races 1, 5 in such a way that an inserting hole 12 faces to the ball 8, and the ball 8 is pressingly inserted into a fitting hole 14. With this arrangement, a bearing is assembled. In the bearing, the inner race 1, the outer race 5 and the retaining race 9 are all made from synthetic resin so as to mutually slide well. Moreover, the retaining race 9 is rotatably fitted to both inner/outer races 1, 5, and the ball 8 is held into the fitting hole 14 having a slightly greater diameter than that of the ball 8, consequently rendering the bearing usable under the state without lubricant.

Title: Digital filter
Inventor: USUI AKIRA
IPC: G11B20/10
Filed: 1986-09-29
Abstract: PURPOSE:To perform a highly accurate arithmetic operation in a short arithmetic word length by dividing a filter coefficient into an exponent and a mantissa and using the mantissa only to carry out a convolutional arithmetic operation. CONSTITUTION:The mantissa data are read successively out of a coefficient ROM 58 in the order of smaller values. These read-out mantissa data are multiplied by the corresponding input data outputted from a selector 52 through a multiplier 54. The values of multiplication obtained by the multiplier 54 are cumulated and calculated convolutionally by an accumulator 60. In this case, the multiplication data is shifted every bit toward the decrease direction (lower direction) by a bit shift circuit 64 every time the exponent data is changed. Thus it is possible to carry out a highly accurate arithmetic operation in a short arithmetic word length.

Title: Semiconductor light receiving element
Inventor: MAKITA KIKUO
IPC: H01L31/107
Filed: 1988-09-14
Abstract: PURPOSE:To provide a semiconductor photo receiving element of avaranshe doubling type with low noise and quick response characteristic by forming on a substrate a laminate structure consisting of a first semiconductor layer of light absorbing layer, a super-lattice structure of avaranshe doubling layer, and a second semiconductor layer of cap layer, and incorporating such an arrangement that the split-off band energy of semiconductor material forming a group of semiconductor layers in super-grating structure is the same as or near the prohibit band energy. CONSTITUTION:On an n-type GaSb substrate 1, a semiconductor light-receiving element is formed from an n-type GaSb light absorptive layer 2, n-type GaSb/ AlSb avaranshe doubling layer 3, and n-type Al0.5Ga0.5Sb cap layer 4. In this strata structure the fundamental construction is obtained by forming the P<+>- region of photo-receiving part. In the GaSb/AlSb super-lattice structure, the thickness of a well layer GaSb is l=180Angstrom , which satisfies so/Eg=1. Therefore, only positive hole generates resonant ionization through split-off band. Therein change in  so/Eg is dull to the thickness of well layer, so that resonant ionizing phenomena can be easily achieved. This exaggerates the ionization ratio and accomplishes quick response with low noise.
