IPC: H01Q13/08
Filed: 1992-09-29
Abstract: PURPOSE:To increase a frequency band range for the characteristic of a microstrip antenna. CONSTITUTION:The dielectric plates 13 and 14 containing at least two layers or more, respectively, and having the different specific dielectric constants are provided together with at least two or more pieces of radiation microstrip patch element 11 set opposite to each other and holding both plates 13 and 14 between them, and a common earth conductor 12. Furthermore both plates 13 and 14 have no fixed thickness and these thickness are varied so that the fixed total thickness is secured when both plates 13 and 14 are laminated together. Therefore the specific dielectric constant of the laminated dielectric plate equivalently varies in the thickness changing direction. Then a resonance frequency of the element 11 also varies in response to the change of the preceding specific dielectric constant. Outputs of these elements 11 are synthesized and the frequency band range is increased.

Title: Flow rate sensor
Inventor: TOMAKI KENJI
IPC: G01F1/22
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a flow rate sensor which can electrically detect a slight flow rate of a fluid simply at a low cost. SOLUTION: A float member 4 is installed inside a tubular body 3 made of a heat resistant glass and whose both ends are fixed and supported by two L-shaped tube joints 1, 2 made of a corrosion resistant metal material such as a stainless steel. The float member 4 is made movable up and down inside the tubular body 3 while being guided by a rod-like guiding member 9 inserted into a guide hole 4c.

Title: Network communication system by radio communication
Inventor: OKAJI HARUMI
IPC: H04W84/12
Filed: 1994-10-26
Abstract: PURPOSE: To realize an environment where network communication is attained by plural groups at different radio channels simultaneously. CONSTITUTION: A host terminal sends a transfer packet subjected to diffusion processing by a selected code (S11). New membership terminal equipment applies inverse diffusion to a received packet by a full diffusion code prepared in the system (S12). A signal level after inverse diffusion is received by a computer main body, signal levels are compared (S13) and a code with a highest level is recognized to be a selection code in the group (S14). A diffusion signal generator is controlled so as to supply the selection code to a transceiver. In this case, since a signal level of a transfer packet after inverse diffusion is a problem, optional data are enough for the packet.  However, the new membership terminal equipment applies inverse diffusion to the transfer packet signal by using a full diffusion code prepared in the system, the signal level after the inverse diffusion processing is received by the computer main body and the signal is kept to be sent for a time enough to compare signal levels.

Title: Bolometer and its manufacture
Inventor: UIRIAMU EFU KIINAN
IPC: H01L27/146
Filed: 1992-09-30
Abstract: PURPOSE: To improve voltage coefficient of a resistance value by providing an absorbing material which heats a pixel main body to a certain temperature in proportion to absorbed radiation and a variable resistance material having electrical resistance in response to the temperature of the pixel main body and permitting current to flow almost parallel to an integrated circuit substrate in the variable resistance material. CONSTITUTION: Infrared ray is applied on the top plane of a pixel main body 120, is absorbed by an absorbing layer 132 and the temperature of the pixel is increased. At that time, the resistance value of a temperature sensing resistance layer 136 changes in response to temperature change, namely, in response to change of IR radiation strength. The resistance value change is observed by an integrated circuit formed on a substrate 122. Current passes parallel to the substrate 122 from an alternately connecting part 138a into the resistance layer 136 and exits downward from the alternately connecting part 38b. Since current is permitted to flow in the horizontal direction by crossing the pixel, contrary to vertically entering and exiting the pixel, a conductive path is very long. Thus, voltage coefficient of a resistance value is improved and resistance with excellent linearity is obtained.

Abstract: PURPOSE:To smoothly separate paper without generating a mark even when curled paper is refed by allowing a scorotron separating charger to have a grid whose a rotate of perforation is changed in the direction vertical to the transfer paper carrying direction. CONSTITUTION:A grid 7 for forming an opening part 20 of a scorotron separating charger 3 is formed by band-like steel wires 21 which is arranged in parallel and reinforced steel wires 22-24 being vertical to the transfer paper P carrying direction, and a rate of perforation of a part corresponding to the center part against the direction vertical to the transfer paper P carrying direction at the upstream side from the reinforced steel wire 24 becomes large. That is, as for both end parts having a large curl, the destaticization quantity is suppressed so that a mark is not generated, and as for the center part, the destaticization quantity is increased so that the paper P can be separated smoothly. In such a way, even when the curled paper P is refed, no mark is generated and the separation can be executed smoothly.

Abstract: PROBLEM TO BE SOLVED: To stabilize a control system by a method wherein the difference between the output signal of a first feedback loop and the output signal of a second feedback loop is obtained by a subtracter and a power to support the levitated pair of a stator is made to be in the linear function of the output signal of a levitation controller. SOLUTION: A power amplifier 10 controls so as to have the value (i<2> ) which is obtained by squaring an exciting current signal (i) detected by a current detector 15 by a second square function device 9 equal to the output signal (iS) of a multiplier 6 by using a second substrater 8. That is, if the output signal (iS) and the square (i<2> ) of the exciting current (i) of an exciting coil C are inputted to the second deductor 8 and (ki ) is a constant, a relation i<2> =ki .iS is obtained. On the other hand, if the output of a levitation controller 5 is denoted by (fS), a relation iS=fS.x<2> is obtained. That is, the power amplifier 10 applies the proportional control to the output signal fS of the levitation controller 5 so as to make the ratio i<2> /iS=ki one.  As a result, a levitation force which is proportional to the output signal (fS) of the levitation controller 5 is obtained and the proportional control is applied to the levitation force, a control system can be stabilized.
