IPC: G01D5/244
Filed: 1988-02-24
Abstract: PURPOSE:To make it possible to average and reduce an error in an angular position, by disposing a pair of detecting elements in separation by (m+1/4)lambda from each other and by computing the sum and the difference of output signals of the detecting elements. CONSTITUTION:A grating disk 3 is held rotatably in the direction theta and has a grating 2 of a light-and-dark pattern formed by dividing one cycle T (360 deg.) equally at a pitch angle lambda on the outer peripheral part. Paired detecting elements 13a and 13b of a detecting unit 9 output electric signals VA and VB respectively in accordance with the rotation of the grating 2, and a sum comput ing unit 14a computes the sum of the signals VA and VB and outputs a phase-A signal phiA, while a difference computing unit 15a computes a difference between the signals VA and VB and a phase-B signal phiB. According to constitution, the signals phiA and phiB are detection signals of two phases corresponding to the relative rotations of the disk 3 and the detecting unit 9, and by disposing the elements 13a and 13b in separation by (m+1/4)lambda [(m) is a plus integer] from each other, an error in an angular position contained in the signals phiA and phiB is averaged. Besides, an error component of an odd-order in the angular position error can be removed.

Abstract: PURPOSE:To obtain a frequency synthesizer operated stably over all channels by forming a PLL so that the input frequency of a phase comparator is changed at a specific condition to a required frequency variable step. CONSTITUTION:A frequency difference signal is subject to 1/N frequency division by the 1st frequency divider whose frequency division ratio is made variable by an external signal and the frequency division output is inputted to a phase comparator 13. The 2nd reference signal 11 is subject to 1/M frequency division by the 2nd frequency divider 12 having to number of frequency division M set by a programmable terminal 1201, the frequency fr is obtained and supplied to one input of the phase comparator 13. The phase comparator 13 feeds the comparison output of two inputs to a control terminal 1501 of the voltage controlled oscillator 15 via an LPF 15 to constitute a PLL as a whole. In such a case, the number of frequency divisions M of the 2nd frequency divider 12 is changed by the condition that the fr satisfies the relation of fr=DELTAF/K (DELTAF is the required frequency variable step and K is a natural number) and the number of frequency divisions N of the 1st frequency divider 17 is changed within a specific range to obtain the required output frequency range and the frequency variable step DELTAF.

IPC: B32B9/02
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To produce a corrugated board box and its recovering system for domestic animal feed. SOLUTION: This corrugated board box for packing domestic feed is made of rice grains, wheat grains and their straws and the corrugated board box becomes edible by domestic animals. The recovery of the boxes as a feed can reduce the transportation cost, because recovery rate of the box increases and the boxes can be crushed in situ. Thus, the crushed boxes recovered all can be sold as a feed for domestic animals, accordingly the amount of waste is reduced, resulting in the protection of the forest resources.

Title: Image data compressing and reconstructing method by vector quantization
Inventor: TANAKA YASUYUKI
IPC: H04N1/41
Filed: 1988-02-24
Abstract: PURPOSE:To prevent the degration of the quality of an image by applying, a higher probable weighting to either one (a) or (b) that is close to said information value, and converting the information when reconstruction information is in a value between a bit of image information (a) and that (b). CONSTITUTION:Image information S is subjected to a block conversion circuit 10 and divided into blocks B, and the image information X at every block B is inputted to a vector quantizer 11. The quantizer 11 selects such a vactor as corresponding to a pair of information X with the least distortion from among the vectors stored in a memory 12 as a code book, and outputs vector discrimination information Dm at every the block B. A demodulator 14 reads the Dm from a recorder 13 at the time of reproducing, and outputs reconstruction information (y) by referring to the memory 12. When the information (y) is in an intermediate value of information (a) and (b) ((b-a) represents the minimum level difference corresponding to the density resolution of an image reproducer 17) a conversion circuit 15 weights either (a) or (b) closer to the information (y) with larger probability to generates information Y'. In a synthesis circuit 16, the information y' is converted to a time sequence information at every picture element to become image information S' and is transmitted to the reproducer 17. This information S' is almost the same as the original information S.

IPC: H01M10/05
Filed: 1994-03-14
Abstract: PURPOSE:To obtain a stabilized lithium secondary battery having excellent characteristics and a long cycle lifetime by including organic solvent made of specific organic fluorine ether compound in the electrolyte. CONSTITUTION:Low viscosity solvent made of organic fluorine ether compound shown by R1-O-R2, R1-O-R2, in which R1, R2 means fluorine alkyl group having the number of carbon atom at 1-10, or R2 means alkyl group.

Title: Heat exchanger
Inventor: YONEDA HIROSHI
IPC: F28F1/32
Filed: 1985-03-04
Abstract: PURPOSE:To extend the operating hours up to a point of a clogging due to the frosting so that the average heating operation efficiency may be improved and the uncomfortable feeling may be reduced during the defrosting operation by forming only the fin leading edge in a waved shape, said fin being situated on the upstream side on the first row heat transmission pipe relative to the ventilated air flow. CONSTITUTION:The waved leading edge area 13 is disposed on the leading edge of fins facing the upstream side of the air flow on the first row heat transmission pipe 12 relative to the air flow (shown by arrow). When operating in the heating mode, the frosting in the E-E section can be reduced in its height for a same amount of frosting because there are waved leading edge areas 13 on the air flow upstream side of the fin 11, making the length of the leading edge longer than the straight type. As a result, the increase of the air flow resistance due to the frosting on these areas can be made less. Although there is a frosting condition similar to the conventional fin in the F-F section, because the frosting height is reduced in the waved lending edge areas 13 in the fin leading edge in the E-E section, the heat exchanger as a whole will display a nearly uniform frosting condition (frosting height).
