Filed: 1988-01-14
Abstract: PURPOSE:To simplify production and adjustment and improve reproducibility by fixing converging rod lenses in optimum positions of incidence and emission of a light emitting element, a light receiving element, and a ferrule and inserting and sticking them onto an optical axis so that their optical axes coincide with three faces of a hexahedral glass block where a wavelength filter is stuck to the junction surface between two isosceles right-angled triangular prisms. CONSTITUTION:Converging rod lenses 22, 32, and 42 convert light beams to parallel rays of luminous fluxes and convert parallel rays of luminous fluxes to light beams. Positions of converging rod lenses are so adjusted that optimum coupling states are obtained in respective housings, and they are fixed. Adjusted housings are fixed to prescribed positions of an enclosure 1. A wavelength filter 10 is stuck to faces having longer sides of glass blocks 8 and 9 formed to isosceles right-angled triangular prisms to form a hexahedron, and jigs fixing cylinder glasses 5, 6, and 7 are inserted onto the optical axis of said enclosure so that optical axes coincide with three faces of this hexahedron, and they are fixed in an optimum coupling state. Thus, a collimator is easily produced and adjusted with high precision and the reproducibility is improved.

Title: Liquid crystal display device
Inventor: KOSAKA TAKAHIRO
IPC: G02F1/133
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To secure safety by stopping a high voltage output while stopping the power source voltage supply to a back light control circuit when the power source voltage is lowered due to the temporal reduction of an utility power source. SOLUTION: When a power source voltage Vcc is a voltage of not lower than a reference voltage to be set with a diode D1 in a power source voltage voltage detecting circuit 1, a transistor Q1 is turned on and a voltage Von is impressed on the base of the transistor Q2 of a power source voltage control circuit 2 to turn the transistor Q2. Then, a transistor Q3 is turned on and then a voltage Vo is supplied to a back light control circuit 3. Moreover, when the power source voltage Vcc is a voltage of not higher than the reference voltage, since the transistor Q1 is turned off and the voltage is not impressed on the base of the transistor Q2, the transistor Q2 is turned off and the transistor Q3 is also turned off.  Thus, only when the power source voltage becomes the voltage of not higher than the reference voltage, it is made possible to stop the supplying of the power source voltage to the back light control circuit 3.

Title: Waveguide type slot array antenna
Inventor: FURUYA TERUO
IPC: H01Q21/00
Filed: 1982-01-19
Abstract: PURPOSE:To increase the number of slots without much influence of the area and frequency of an antenna by forming a rectangular waveguide between slots in a channel shape in the opposite direction to a slot formation surface. CONSTITUTION:The axial direction of rectangular waveguides 1a, 1b and 1c is regarded as an X direction and their array direction is regarded as an Y direction. Mutual Y-directional intervals of slots 2a, 2b, and 2c are determined by the lateral H-surface size of the rectangular waveguides 1a-1c, and the Y- directional number of the slots 2a-2c is increased only by reducing the lateral H-surface size of the rectangular waveguides 1a-1c. In this case, X-directional intervals of the slots 2a-2c is narrowed down apparently and the X-directional number of the slots 2a-2c is increased because of the channel-shaped waveguide 3. Consequently, the channel-shaped waveguide 3 increases the number of the slots 2a-2c without being influenced by the area and frequency of the antenna much and while the gain of the antenna is improved, an antenna opening distribution is controlled successively.

Abstract: PURPOSE:To attain drawing by scanning a sample with an electron beam with sectional area including an area diiferent in reflection factor with the sample, by detecting the generated electron beam, and by modulating brightness by this detected electron beam synchronizing with deflection. CONSTITUTION:The sectional area of electron beam E2 is l2=S0 and mark P1 is d<2>=S1 with S1<=S0/3; and the reflection factor is (r1) on the mark and (r0)< (r1) on the other. When the electron beam scans on An and Ay including P1 in the order (n1), (n2)..., it is found by detecting the electron beam reflected from  region Q that signal currents obtained from Q and any part except Q have a difference of (r1-r0)S1 i.

IPC: G11C11/14
Filed: 1979-01-23
Abstract: PURPOSE: To prevent generation of idling phenomenon by shaping a non-gap cylindrical magnetic domain transfer path into a form which satisfies prescribed conditions.  
     CONSTITUTION: The magnetic pole moves through parts Ai→Bi→Ci... of non-gap cylindrical magnetic domain transfer path 41 together with the rotating magnetic field and goes across cylindrical magnetic domain transfer path center axis 1 at a moving time of parts Ci→Di and Ei→Fi. Since edges of chevron patterns 11... are shifted and gap parts are connected in respect to the form of transfer path 41, positions Di and Fi which the magnetic pole reaches across axis 1 become magnetically near from positions Ci and Ei before reaching. Consequently, generation of idling phenomenon can be prevented to obtain a high-density and high-yield cylindrical magnetic domain memory element which can be driven with a low magnetic field.
