IPC: H04B1/707
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a frame synchronization detection circuit for a DS-CDMA (direct sequence-code division multiple access) which is small in circuit scale and low in power consumption. SOLUTION: A signal with a frame configuration, consisting of plural slots having an information symbol and a pilot symbol with a prescribed pattern, is received and spread inversely by a matched filter. The signal subjected to inverse spread processing is converted into data into 1-bit, denoting a polarity by a quantization circuit 11, subjected to delay detection by a multiplier 13, and stored sequentially by delay circuits 14, 15. Multipliers 17-19 multiply the outputs of the delay circuits 14-16 with a pilot symbol pattern, and an adder 20 provides an output of the sum. Frame synchronization is detected by detecting the peak. Furthermore, the inverse spread signal and the pilot symbol pattern are multiplied directly without being subjected to delay detection, and the sum is discriminated so as to detect frame synchronization.

Filed: 1980-12-25
Abstract: PURPOSE: To prevent soil on die lips, by adding TiO 2  surface-treated with aluminum oxide hydrate to a polyolefin resin coated on paper.  
     CONSTITUTION: Aluminum oxide hydrate is used for surface-treating TiO 2  in 0.2W1.2wt% of TiO 2  expressed in terms of Al 2 O 3 , and a polyolefin resin composition containing this TiO 2  is melted and extruded through slit dies in a film form, and coated on at least one side of a paper or synthetic paper base. Polyolefin containing TiO 2  causes soil in a needle or icicle form at the edges of the die lips, resulting in forming a longitudinal streak or an uneven coat. Use of TiO 2  surface-treated with said amount of alumina hydrate can prevents such trouble. Use of less amount of it causes discoloration of a white ground and soiling of the die lips.

Filed: 1986-08-07
Abstract: PURPOSE:To reduce the size of a detector by measuring the reflectivity of the ultrasonic wave which is projected to a waveguide having soundproofness from the end thereof and is reflected from the surface adjacent to fuel. CONSTITUTION:The ultrasonic wave which is projected to the waveguide 4 from one end thereof by a receiver 9 in common use as an ultrasonic wave transmitter and is reflected by the adjacent surface 7 is received by the receiver 9. The acoustic impedance of the fuel is detected and the approximate components of the fuel; for example, alcohol content and octane value or titanium value are detected from said acoustic impedance. The sound velocity of the waveguide 4 adjacent to a fuel cell 3 branched from a fuel passage 1 fluctuates according to the temp. of the fuel but can be easily subjected to temp. correction by measuring the time after the projection of the ultrasonic wave before the reception of the reflected ultrasonic wave. The detector is, therefore, made of the simple constitution essentially consisting of the waveguide having the soundproofness as well as the ultrasonic wave generating means and receiving means, by which the reduction of the size thereof is permitted.

Title: Induction motor
Inventor: NAKAWA YASUMASA
IPC: H02K17/02
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To obtain an induction motor whose vibration is reduced and whose noise is reduced, by a method wherein the junction part of a frame to a stator is arranged in every node position of a circular vibration caused by an electromagnetic force, and the thickness and width of the frame at the junction part are specified. SOLUTION: When junction parts 3 to a frame 1 are situated in node positions of a circular vibration, the vibration is hardly transmitted to a frame 1. However, in order to arrange the junction parts 3 in the node positions of the circular vibration, the rigidity of the frame 1 at the junction parts 3 must be made higher than that of other parts. Then, when the height of steps at the frame 1 in the junction parts 3 is set at 1.3 to four times or lower of the height of parts other than the junction parts 3, the suppression effect of the vibration is obtained. In addition, when the width of the frame 1 is set at the thickness of higher of the frame 1 in parts other than the junction part 3 and at 1/3 or lower of the pitch width of the junction parts 3, the junction parts 3 can be situated in the node positions of the circular vibration caused by an electromagnetic force.  As a result, the junction parts 3 can be arranged in the node positions of the circular vibration, and a vibration noise can be reduced.

Abstract: PURPOSE:To minimize the illuminating difference between a substrate surface and the inner wall of a through hole by irradiating exposure light, with the vertical component eliminated or decreased, on the substrate with the through hole. CONSTITUTION:A printed wiring board 22 with the through hole 28 is coated with liquid photosensitive resin 26. Then the vertical part of light from a light source 21 is eliminated or decreased and the printed wiring board 22 is irradiated by the light with the difference between the vertical illuminance and the horizontal illuminance decreased through a mask 27, to harden the resin 26 and to form a protective coat. Here, for example, an obstruction 23 is provided directly below the light source 21 to shut out the vertical part of light making incidence on the printed wiring board 22 from the light source 21, and by changing the curvature, etc., of a reflecting board 24, the exposure light is made to be of the desired angle of incidence. Thus the balance of illuminance of the exposure light is made better, and the resin on the surface and the resin inside the through hole are hardened to the same extent.
