Title: Portable caloimeter and method for featuring colored surface
Inventor: RARII II SUTEIINHOUKU
IPC: G01J3/10
Filed: 1989-12-19
Abstract: PURPOSE: To introduce and characterize the color constant of a sample surface in terms of the optical characteristics of a color surface or particularly colored surface containing metallic particles by using three multiangular spectral luminous intensity measured values. CONSTITUTION: Illumination source lamps 11a, 11b, 11c operate at a predetermined color temperature. The lamps 11a to 11c are monitored by two photodiodes 22. The photodiode 22 generates a voltage signal proportional to the lamp emitting amount in the blue and red regions of the spectra. The light source is plotted by the spectral power distribution curve, an object is plotted by spectral reflectance and a detector is plotted by a spectral response curve. The combination of the curves give the stimulus, i.e., signal represented as numeric color descriptors X, Y, X (three stimulus values). Thus, the three stimulus values of certain color calculate reflectance factor data R in combination with the data x, y, z of human eye's sensitivity and the emitting illuminance of the source E.

Inventor: MINAMI SHOGO
IPC: H04J3/14
Filed: 1994-12-28
Abstract: PURPOSE: To provide the slave station equipment for time division multidirectional multiplex radio communication system with which a transmitting output can be prevented from being emitted at wrong transmission timing by the abnormal operation of a radio circuit part itself. CONSTITUTION: A transmission logic circuit 2 converts transmitting data into a burst signal based on a transmission timing signal. The burst signal is modulated, converted into a radio signal frequency band later and outputted after its power is amplified by a transmitting radio part 3. An ALC circuit 4 monitors the transmitting output level of the transmitting radio part 3. When an ALC voltage is supplied during the period in which the transmission timing signal is not inputted, a transmission control circuit 5 forcedly turns off the transmitting output of the transmitting radio part 3 to a transmission/reception multicoupler 6 by cutting off the supply of the ALC voltage from the ALC circuit 4 to the transmitting radio part 3.  A reception logic circuit 9 demodulates the output signal of a receiving radio part 8, outputs it to an output terminal 10 and extracts a transmission output timing signal.

Title: Sand for laying block
Inventor: HONDA MASARU
IPC: E01C13/04
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To prevent blocks from being blown away by wind or flowing out with rainwater and prevent mold or plants like grass or moss from growing, by at least impregnating sand for laying blocks with a hydraulic material sized to range in a specified scope. SOLUTION: Sand for laying blocks is impregnated with at least a hydraulic material sized to range in 10μm-0.5mm. As the hydraulic materials, cement or cement clinker is used. When the material size is finer than 10μm, it is too fine to stuff it into joints of blocks and also wipe well the rest on the blocks and further, it becomes hard to penetrate the sprinkled water after stuffing when it is too fine and hence, the joints are not evenly solidified. On the other hand, when the size is larger than 0.5mm, a sufficient binding force can not be obtained and it is crumbled. The sand for blocks is laid on a roadbed when installing blocks or stuffed in joints of blocks.

Filed: 1993-12-27
Abstract: PURPOSE:To control electron beam intensity with an electron beam left as holding its beam diameter and energy half value width as far as possible even after monochromatically forming energy of the electron beam. CONSTITUTION:When an electron beam is applied to irradiate a monocrystal solid surface 4, in elastic scattering without changing energy, 81 electron beam reflected in a mirror surface direction and art electron beam diffracted in a direction except the mirror surface direction are radiated. Of the electron beams, only the electron beam elastically scattered in a single direction is considered. Here to the same part to a spot on the solid surface irradiated by the electron beam, when light from a laser 6 or the like is applied through a view port 8, since an electron condition o.f the solid surface 4 receives disturbance, intensity of the elastically scattering electron beam is reduced. Thus by adjusting intensity of trradiation light, a decreasing amount of intensity of the electron beam, radiated from the solid surface, can be controlled.
