Title: Mortar material and execution using the same material not requiring kneading
Inventor: MIZUSHIMA KAZUYUKI
IPC: C04B28/02
Filed: 1990-09-26
Abstract: PURPOSE:To obtain hardened materials only by adding mortar to water, to simplify execution and to shorten an execution time by using fine aggregate having specific particle size distribution. CONSTITUTION:A mortar material consisting of cement, a rapid hardening admixture of cement and fine aggregate having 2.5 mm maximum, comprising 50-80 % particle having <=0.5 mm particle diameter is used. The mortar material is added to water, hardened and used, for example, to fix underground of utility pole, etc. Consequently, since kneading is not required, time and labor for kneading are not required, plants for kneading machine and paste casting are made needless and execution is simplified. Since the mortar material is hardened in several minutes, an execution site can be released in a short time. When the fine aggregate has >2.5 mm maximum particle diameter, the fine aggregate is readily separated during addition of the mortar material to water. When the amount of particles having <=50mm is <50 %, the fine aggregate is easily separated during blending of mortar and when the amount exceeds 80%, dispersion of water is bad and there is possibility of leaving unreacted part of cement.

Title: Evaporation cooling machine
Inventor: KYU HOKYO
IPC: F25B39/04
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To enhance heat exchanging rate while reducing manufacturing cost and fixing cost by passing air through an air passage, i.e., the gap of air layers, and evaporating moisture absorbed onto a moisture absorbing material at normal temperature and performing heat exchange by absorbing heat being discharged from refrigerant at the time of liquefaction. SOLUTION: Refrigerant tube body 210 of an evaporation cooling machine is coated with a moisture absorbing material 202, i.e., the heat conduction contact face in an air passage 212 is coated with a moisture absorbing thin film material (moisture absorbing material 202), so that suction water from a water discharging unit adheres to the moisture absorbing material 202. Moisture adheres to the moisture absorbing material 202 when air is blown at high speed into the air passage 212 is evaporated at normal temperature and then condensed under extremely low cooling pressure by lowering the refrigerant temperature significantly. Further, function of the moisture absorbing material 202 is sustained by combining the moisture absorbing and moisture keeping functions thereof with the periodic moisture absorption ratio supplementary control of a moisture absorption control printed board.  Since moisture absorption can be brought close to moisture evaporation, moisture absorption, collection and circulating can be dispensed with.

Title: Waveform data compressing method
Inventor: UENO ISOO
IPC: G10L19/00
Filed: 1994-10-21
Abstract: PURPOSE: To obtain a waveform of optimum quality over a predetermined range of data compressibility. CONSTITUTION: Plural bit strings of bit string length corresponding to the number of samples of waveform data digitized at an optional frequency are prepared, and made to correspond to the respective samples in the time-series order from the left-end bit of each bit string; and a bit value 0 indicating that the sample is not used and a bit value 1 indicating that the sample is used are given (step 100). Samples corresponding to the bit values of the respective bit strings are connected by straight lines to restore a waveform (step 101), and evaluated values are calculated from a calculation expression predetermined depending upon the number of samples in use and the overall length of the waveform (step 102). Genetic algorithm is applied, and selected, crossed, and mutated (steps 103-106), and the procedure from the evaluation is repeated.  Solid bodies having bits of the value 0 at the same rate with the compression ratio to be found are selected to generate a data file (steps 107 and 108).

Title: Satellite tracking apparatus
Inventor: HATA TETSUO
IPC: G01S3/44
Filed: 1991-09-09
Abstract: PURPOSE:To obtain a simple and inexpensive satellite tracking apparatus without lowering performance as compared with the conventional type. CONSTITUTION:A signal received from an antenna 21 is converted into a specified frequency signal with a frequency converter 22, a detection signal Vl corresponding to the level of the signal converted is outputted with a detector 23 and further, a low frequency component Vf is outputted through an LPF 24. The results Vl-Vf of subtraction thereof are compared with a reference potential Vr by means of a comparator 26. When Vr>Vl-Vf, a control is performed by a clock signal of a flip-flop 32 so as to switch the direction of rotating a motor 34 for driving the antenna after a fixed time. When Vr<Vl-Vf, a control is performed to maintain the direction of rotating the motor. This eliminates the need for a complicated circuit of a sampling/holding circuit or the like thereby enabling the obtaining of a simple and inexpensive satellite tracking apparatus.
