Title: Radar apparatus for automobile
Inventor: SEKINE CHOGO
IPC: G01S7/282
Filed: 1992-02-18
Abstract: PURPOSE:To use a small-sized antenna which can be mounted on a passenger car and to control the beam width of the antenna from a short distance up to a long distance equivalently and over a full road width by a method wherein a transmission power or the gain of a receiver is controlled according to a distance to be detected. CONSTITUTION:A signal for distance-measuring use is transmitted forward from a transmitter 14 via an antenna 10 for transmission reflected waves from an object are received by means of a receiver 18 via an antenna 12 for reception. At this time, when radio waves are transmitted at a definite power from the antenna 10, a reflected power Smax from an object situated in the middle point between the antennas 10, 12 and a maximum measuring distance Lmax becomes largest. A transmission power (or the gain of a receiver) is controlled by a controller 26 according to a change in a reception power. That is to say, the reception power (or the gain of the receiver) corresponding to the change portion of the reception power is corrected. Even when an object related to a reflection is situated at any distance, the reception power is controlled so as to be definite. Thereby, the common directivity of the antennas 10, 12 can be controlled equivalently and over a full road width irrespective of whether a distance is large or small.

Abstract: PURPOSE:To make it possible to form a hollow molding without using a core by injecting a resin which adheres firmly to a material resin for an inner hollow form and is molded at an adequately higher temperature than the material resin of the inner hollow form, into an injection molding space, and forming an outer peripheral surface layer which covers the outer peripheral surface of the inner hollow form integrally on the outer peripheral surface of the inner hollow form. CONSTITUTION:An inner hollow form 1 molded by assembling split parts is set in the cavity 2 of an injection molding die B for a finished product hollow molding. This cavity 2 has a shape and a size which are equivalent to the outer profile of a hollow molding as a finished product, and is one size large than the inner hollow form 1. Next, an injection-molding material for an outer peripheral layer which firmly adheres to the material resin of the inner hollow form 1 and is molded at an adequately higher resin temperature than that of the material resin of the inner hollow form 1, is injected into an injection molding space 22 formed between the inner hollow form 1 and the inner surface of the cavity 2.

Title: Wedging device for elevating leg column of off-shore working platform
Inventor: TATSUKUCHI MASAMITSU
IPC: B63B35/44
Filed: 1984-02-22
Abstract: PURPOSE:To reliably secure a working platform to a leg column, by a method wherein a wedge-shaped shim, which moves and energizes a gap, produced due to unproper engagement between a rack and a lock tooth during engagement of the rack with the lock tooth, in a weding direction, is mounted to the tooth surface of the lock tooth of a leg column lock body. CONSTITUTION:A lock tooth 9 of a leg column lock body 18 is engaged with a rack 3 of a vertical leg column 2 in a condition in which a shim support plate 25 is energized in the direction of a dedendum through the elastic force of springs 26, and a piston rod is expanded by means of a cylinder device 29. With a crank member 28 rotated, a spring tightening part 31 of the crank member is moved to the top of tooth side. The shim support plate 25 is moved in the direction of a top of tooth, and a wedge-shaped shim 23 is energized in a weding direction within a gap, formed due to unproper engagement between the rack 3 and the lock tooth 9, for wedging. This, since the lock tooth 9 is brought into press contact with the tooth surface of the rack tooth 3 through the medium of the wedge shaped shim 23, causes a fixed holding load, applied on a tooth surface, to be uniformly dispersed to teeth and prevented from concentration on a small number of specified teeth.
