Title: Rectangular microstrip antenna
Inventor: YOSHIKAWA YUKIHIRO
IPC: H01Q13/08
Filed: 1985-07-15
Abstract: PURPOSE:To erase a cross polarized wave component by providing symmetrically two pieces of feeding points against the center axis being parallel to a main polarized wave direction of a rectangular radiation conductor element, and executing a feed by an equal phase and an equal amplitude. CONSTITUTION:When a rectangular radiation conductor element 2 constituted of a microstrip is excited by one feeding points 5, since the feeding point 5 is shifted from the center axis being parallel to a (y) axis of the rectangular radiation conductor element 2, a surface current of the (y) axis direction being uniform in the (x) axis direction, and a surface current of the (x) axis direction being uniform in the (y) axis direction flow and become elliptical polarized waves, but when said element is excited so as to become an equal phase and an equal amplitude to one feeding point 5 by a feeding point 11 of a symmetrical position to the feeding point 5 against the center axis being parallel to the (y) axis, each surface current of the (x) direction being uniform in the (y) axis direction is offset each other, and only the surface current of the (y) axis direction being uniform in the (x) axis direction is added. As a result, only a linearly polarized wave of the (y) axis direction is radiated, and a cross polarized wave component is erased completely. In this regard, when the same feeding point is provided in the (x) axis direction, as well, a circularly polarized wave antenna can be constituted.

IPC: F02D41/14
Filed: 1980-11-07
Abstract: PURPOSE: To equalize the control level and improve the control characteristics by skipping the reversing of the signal from lean to rich etc. of an oxygen concentration detector for exhaust system when such reversing occurs within the predetermined period after the previous reversing.  
     CONSTITUTION: The signal of an oxygen concentration detector is processed in the step 100 in an electronic control unit and is determined whether or not it is lean in the step 101. If it is lean and the rich flag is set, it goes to the step 103. In the step 104, whether or not the number of reversing is larger than 20 and the amount of the skip R1 is entered in n 1 . In the step 107, the counter is compared with 10 and the intergrated value K 1  is entered in n 1 . The amount of the skip is added to the feedback correction coefficient F(A/F) in the step 106. The program for not lean goes through similar steps, i.e., the level is skipped by the amount of previous skip n 1  every time the reversing occurs.

Inventor: KAWAI YOSHIAKI
IPC: H01L21/02
Filed: 1979-11-30
Abstract: PURPOSE:To enable a high-speed operation with a simple construction eliminating polar alignment by stamping components as carried in without turning up to 180 deg.. CONSTITUTION:A signal for polarity measured 23 is transmitted to a driving section 8 while a component stays at the home position. When a component 5 with a negative lead 2 comes under a transfer roller 33 of a stamping section 24 on the side A, an arm 34 is pushed up to stamp the body of the component stopped at the home position on the side A. Then, the arm is lowered and the component is returned onto a conveyor. When a component 5' with a positive lead comes to the side A, a polarity identifying signal allows the body thereof to be driven 28 to the specified position. The roller 33 is moved to the side B where the arm 34 is moved up to stamp. This simplifies and miniaturizes the entire mechanism thereby assuring a high-speed action without trouble.

IPC: G11B23/087
Filed: 1982-09-08
Abstract: PURPOSE:To increase the hooking force, to eliminate a pressed dent and to facilitate an easy automatic insertion with pressure for a tape hooking device, by having an equal radius for outer circumference surfaces of a clamper and a reel hub, and hooking a tape by means of a projected part within the recess of the reel hub and a recessed part of the clamper. CONSTITUTION:An equal radius R is set for both the outer circumference surface 2 of a reel hub 1 and the curved surface 5a of a clamper 5. Projected parts 3c and 3d are formed at the center of a recessed part 3 of the hub 1; while the clamper 5 contains recessed parts 5e and 5f which are fitted to the parts 3c and 3d respectively. When the clamper 5 is inserted with pressure into the part 3 together with a tape 4, the tape held between these recessed and projected parts to obtain a large hooking force. Furthermore no pressure trace of the clamper 5 remains to the tape 4 owing to the equal radius R. Thus the level variation is prevented. The clamper 5 can be inserted easily and automatically by a pressing machine owing to a simple columnar shape of the clamper.

Abstract: PROBLEM TO BE SOLVED: To provide an organic EL print head wherein the efficiency of an optical element is high and a life and a luminance of an organic EL element are good. SOLUTION: Films of a protection layer 13, color filters 14 (14R, 14G, 14B) for R, G, B colors, an overcoat layer 15, an anode 16, an insulation layer having an aperture 17a, an organic layer 18 (a hole injecting layer, a hole transporting layer, a light emission layer) and a cathode 19 are provided on a fiber array plate(FAP) 10. A material having a light emission spectrum of which range is wide enough for a visible range is used for the light emission layer so that a full-color image can be formed by a photosensitive material of a recording medium. As a light transmission efficiency is improved to be a roughly fifty times of that of a conventional one, it is possible to obtain image quality roughly equal to that in a conventional one even at 200 cd/m2.  As a result, the expected life of a half value period of luminance becomes over 10000 hours, i.e., 500 times of that in a conventional one. A power consumption becomes a ratio of 1/50 of that in a conventional one. A printing speed is markedly improved. The structure is allowed to be compact as compared to heretofore. The resolution is raised and the chromatic aberration is eliminated and the heat resistance and the abrasion resistance are improved.

Abstract: PURPOSE:To determine the degree of the faults in the pull-off of the trolley wire accurtely by using the displacement data by an optical method and the data sensed by a probing pin, compensating the data to the same measuring position, and computing the pull-off angle. CONSTITUTION:The probing pin 6 is provided on a boat body 5' in a fault sensor, and contacted with the pull-off 3. Thus operating positions d are sensed. The trolley wire 1 is scanned by laser light 8 by an optical displacement type measuring device 9. The displaced amount D is sensed by the time from a starting point ST to a pulse 1' which is caused by the reflected light. Said operating positions d and the displaced amount D are stored in a specified electric circuit. The displaced amount D corresponding to the positions where the probing pins 6 has been operated is read out by the address control of the distance pulse. The angle between the pull-off 3 and the boat body 5 is computed by the equation tan theta=height of probing pin h/(d-D). Thus the data is compensated to the same sensing position, and the degree of the fault can be determined highly accurately.
