Title: Thermal analysis
Inventor: OKAMOTO SHIGEKI
IPC: G01N25/20
Filed: 1988-07-12
Abstract: PURPOSE:To make an accurate and rapid analysis while preventing a reaction of a sample with a sample holder by placing the sample in the sample holder made of aluminum nitride in the thermal analysis. CONSTITUTION:A differential thermobalance (DTA) or a differential scanning calorimeter (DSC) is used in the thermal analysis. In this case, aluminum nitride is used as the material for the sample holder for a sample to be analyzed. The material is a ceramic, and has low reactivity toward other materials. The heat conductivity is about ten times that of aluminum and about two times that of platinum. As a result, the start and end of the reaction are rapidly detected, and a desired thermal analysis can be accurately made even when the method is used in the thermal analysis of a material easy to react with platinum.

Abstract: PURPOSE:To obtain a large signal by a compact device with good resolution, by a constitution, which comprises a pin made of a magnetic body, whose tip is of a rectangular shape, a magnet, a coil, and an outer tube made of a magnetic body, whose protruded surface of the pin has a rectangular shape. CONSTITUTION:A coil 22 is wound around a bobbin 21. A pin 23 made of a magnetic body is inserted into the central part of the coil. A magnet 24 is attached to the rear part of the pin. In this constitution, the separation of the pin 23 in the forward direction from an outer tube 25 is prevented by a collar 23a. A tip 23b of the pin 23 has a rectangular shape. Therefore, when the pin faces a gear shaped material to be detected, a large output can be obtained efficiently. When the length of the long side of the tip 23b equals to the thickness of the tooth of the gear, the maximum output is obtained with the smallest device. A protruded surface 25b of the pin 23 made of the magnetic body is made to be a rectangular shape along the tip 23b of the pin 23. Therefore, the magnetic flux leaking from the pin 23 can be made uniform and sharp, the frequency characteristics are improved, and the resolution is also improved.

Title: Spray type burner for heater of vehicle
Inventor: HANDA OSATOSHI
IPC: F23D11/24
Filed: 1981-10-29
Abstract: PURPOSE:To cool off the inside wall of a liner, and to stabilize flames, in the titled burner, by simultaneously securing both an air flow which flows in filmy state from a swirl chamber along the inside of a linear, and an air flow accompanied with turbulence which flows so as to be swallowed up in front of a fuel injection nozzle. CONSTITUTION:Combustion air being fed with pressure through an air inducing duct 28 is fed into a swirl chamber 27 in the state of a swirling flow, and the most part of a flow is injected into a liner 22, passing through a gap 34 which is provided along the external periphery of a baffle plate 30. A part of the air A proceeds to the axial direction, swirling along the internal periphery of an outer casing 21, flowing in layer, being pressed against the inside wall of a liner 22 of which diameter is increased by one stage, by a centrifugal force produced by swirling. On one hand, the other part of the air B is sucked into the downstream inside of a baffle plate 30 to become a slip stream accompanied with turbulence, since the internal periphery of an outer casing 21 covers the external periphery of a baffle plate 30. Fuel sprayed from a fuel injection nozzle 24 is thus diffused and mixed with it in good condition.

Filed: 1985-08-08
Abstract: PURPOSE:To increase image read speed by arranging two optical fiber bundles closely as a front and a rear bundle in the transverse direction of an original and detecting the density of the original through one optical fiber bundle. CONSTITUTION:An original image input array 2 and an original density array 3 consisting of optical fiber bundles are arranged at alight signal input part 1. When the original is read, the light signal input part 1 is scanned to read reflected light from the original by the image signal input array 2 and original density input array 3 respectively. Then, an original image is inputted to an image sensor array from an image signal output array 5. The signal of a density signal output part 6 is inputted to the amplifier of a control circuit. Then, the signal is converted by an A/D converter 8 into a digital signal and an input/ output LSI 9 selects and outputs control signals for controlling a proper development bias and/or the quantity of exposure on the basis of the control signal from a CPU 10. Thus, the original density and image are read by making a scan once and the development bias and the quantity of exposure are controlled to make recording density constant.

Abstract: PURPOSE:To prevent data mis-demodulation by obtaining a reception signal and a reference signal and changing a threshold value suited to the data modulation when a level of a signal representing the obtained correlation reaches a prescribed level or over. CONSTITUTION:When an output of a matching filter 3 exceeds the 1st level (VSH1 at a time t1, a decision output signal from a correlation decision section 6 drives a phase synchronizing circuit 5 to synchronize the phase of the succeeding reception signal an a reference PN code, and a demodulation section 4 demodulates data according to the relation between an output of the filter 3 and threshold values (VSH1, -VSH1). When the output of the matching filter 3 exceeds the 2nd level (VSH2) at a time t2 the decision section 6 triggers the timer counter circuit 7 to start counting and the threshold value of the demodulation section 4 is set alternately to the 2nd level (VSH2, -VSH2) and the 3rd level (VSH3, -VSH3) based on the said time counting operation.

Abstract: PURPOSE:To obtain a system excellent in economization and reliability without the increase in the quantity of hardware and delay of signal attended with the number of optical loops and nodes by connecting a node to an optical loop via an optical matrix. CONSTITUTION:A control section 39 of a node 130 having a communication request starts the analysis of information received by optical receivers 32, 33 from an optical loop 11 via an optical matrix switch 120 and also sends transmission information to an optical loop 110 selected through the changeover control of the switch 120 in advance from an optical transmitter 31. When the transmission is enabled as the result of analysis, the transmission is continued and when disabled, the transmission is stopped and the procedure is repeated till the transmission enable. The information sent to the loop 110 is sent to the loop 110 while the transmission delay on the loop 110 is taken as an integral multiple of the master frame at a master module 14. That is, the information is restored to the switch 120 while being normalized to the period of the master frame. While the transmission information is returned to the node 130, the communication is attained with the node in the information address.
