Title: Device for preventing radiation of tuner
Inventor: KOUZU MITSUHIRO
IPC: H04B1/16
Filed: 1983-10-05
Abstract: PURPOSE:To prevent a part of a standing wave from being radiated externally by winding a lead wire onto an outer circumference of a coaxial cable as a transmission line and connecting both winding ends of the conductor to a point of a shield case covering a tuner main body section. CONSTITUTION:A local oscillation frequency control circuit 1 is provided separately as the tuner main body section 2 functioning as a signal source, and a tuner is constituted by feeding-back a local oscillation output from the main body section 2 to the circuit 1 as a load via the coaxial cable 11. The conductor 16 is wound on the outer circumference of the cable 11 in this tuner, both ends 16a, 16b of the conductor 16 are connected to one point 17 of the tuner main body case and the conductor 16 forms a lead trap of the local oscillation output radiated from the cable 11. Thus, the leakage of the local oscillation output of the tuner adopting, e.g., the frequency synthesizer system to the external part is prevented.

Title: Offset antenna
Inventor: MASUJIMA TOSHIO
IPC: H01Q19/19
Filed: 1993-07-27
Abstract: PURPOSE:To provide an offset antenna in which structure can be simplified, strength can be high, a wind load can be reduced, and manufacture can be easy by fixing the casing body of a truncated cone shell to the outer peripheral side plate of a main reflection mirror, and connecting a reinforcing shell with it. CONSTITUTION:The large diameter side of a casing body 28 of the truncated cone shell using an axis C-C orthogonally crossing a rotary axis B-B of a side plate 21 of a cylindrical shell fixed to the outer periphery of a main reflection mirror 2 as the rotary axis is connected with the side plate 21, and a reinforcing shell 30 constituted of one part of a rotary shell is connected with the side plate 21 and the casing body 28. Thus, the internal force of the side plate 21 is transmitted through the internal force of the reinforcing cell 30 to the internal force of the casing body 28, so that a rigid joint can be formed without generating any stress concentration, and the wind load can be reduced by preventing the disturbance of a stream line by the reinforcing shell 30. Also, the crossed axes angle of the casing body 28 constituted of a changing elliptic enveloping surface against the side plate 21 can be reduced, so that the stress concentration can be reduced, and the wind load can be reduced. Therefore, the offset antenna whose structure can be simplified and whose manufacture can be easy can be obtained.

Title: Interference wave removing unit
Inventor: YAMASHITA TOSHIZANE
IPC: G01S7/527
Filed: 1994-07-15
Abstract: PURPOSE:To remove the interference wave positively from an ultrasonic echo by setting a threshold value and removing only such echo as having amplitude variation higher than the threshold value. CONSTITUTION:A ROM 5 comprises a threshold switch 6 for storing different data depending on the threshold value and selecting a desired ROM. Since the interference wave has sufficiently high amplitude and the repetitive frequency thereof is different from that of the receiving pulse, the sampling point where the interference wave appears can not be determined. A threshold value is thereby determined and only such echo as having amplitude variation exceeding the threshold value is removed as an interference wave. In other words, such echo as having amplitude variation within the threshold value is not removed.

Title: Device for inspecting inside of conduit
Inventor: WADA TORU
IPC: H04N7/18
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To prevent a laid power cable from being hindered when the image of the cable is picked up or the cable is illuminated by such mud that is apt to stick to the surface of the cable by forming sectional shape of the separated surface-side edge of the sliding surface of the main body of an image picking-up section which slides on the cable, in a semicircular shape which is protruded or recessed in the direction perpendicular to the advancing direction or in a shape perpendicularly cut off straight line. SOLUTION: An image picking-up section 1 is provided at the front end of a thrust rod 33, and the rod 33 is thrust in the image picking-up section 1 so that the main body 21 of the section 1 can slide on a power cable 3. Since the front portion of the main body 21 is separated from the surface of the cable 3, the mud adhering to the surface of the cable 3 gets in the clearance section between the separated surface 22 and the cable 3. In addition, since the sliding surface 23 in the rear portion of the main body 21 slides on the surface of the cable 3, the mud is scraped off by means of a stepped surface 24 at the front end of the surface 23. Therefore, the cable 3 can be inspected by picking up the image of the cable 3 with a camera 10 and a light 11 while the main body 21 is moved along the cable 3.

Title: Voltage controlled oscillator
Inventor: KURISUTOFUAA SHITERA
IPC: H03B5/24
Filed: 1992-07-13
Abstract: PURPOSE: To provide a voltage controlled oscillator which is not affected by power noise so much, by specifying the number of amplification stages and total phase shifts in a frequency which is previously set. CONSTITUTION: Four differential amplifier stages 10, 12, 14 and 16 connected to a loop are provided. When power is supplied, the oscillators are designed to generate the sine differential signals of small amplitude. This is to set the total phase shift of the loop, namely, the phase shift between output V4 and input V0 to be 360 degrees. The individual differential amplification stages are designed to give output signal phases shifted from the input signals by 45 degrees in the desired frequency and to possess a small signal gain larger than one in the desired frequency. Thus, the fluctuation of power similarly affects both inputs by designing the individual stages to receive and supply the differential signals. Thus, influence to the differential signals becomes minimum. Consequently, the influence of the noise of power can be reduced.

Title: Electronic control unit
Inventor: KONDO HARUHIKO
IPC: G06F11/00
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To surely write the latest data back to an electrically erasable programmable read only memory(EEPROM) without affecting control at the time of copying data from the EEPROM to a random access memory(RAM) and controlling a prescribed controlled system. SOLUTION: When new data to be immediately written back are generated in an EEPROM 16 as well while application processing is executed for controlling the prescribed controlled system by data copied from the EEPROM 16 to a RAM 13, on the side of application processing, a write request is generated. Since real write-back based on this write request is executed by any other EEPROM write processing, application processing is interrupted just in extremely short time. Thus, important data are prevented from being destroyed or broken by any trouble such as hit of a power source and control, and the control for which real-time property is regarded important, is executed without trouble.

Filed: 1985-08-26
Abstract: PURPOSE:To eliminate influences of a stray light due to a scattered light and emphasize features of a sample shape to observe it by using a laser light source as the illuminat ing light source and changing quickly the length of the optical path of a reference signal which is reflected on a reference mirror and is returned to a beam splitter. CONSTITUTION:A piezoelectric element 11 is included in a reference optical path length quick changing means which is attached to a reference mirror 10 and oscillates it in the direction of the optical axis (the direction of an arrow) in a high speed (for example, at 100Hz frequency with 300mum amplitude). The laser light emitted from a laser light source 2 is divided into two by a half mirror 5, and the transmitted illuminating light which is one divided light passes a reference-side objective lens 7-2 and is reflected on the reference mirror 10 and is returned to the half mirror 6 as the reference light and goes to the side of a focusing lens 12. The reflected illumi nating light which is the other divided light passes a sample-side objective lens 7-1 and is reflected on a sample 8 and is returned to the half mirror 5 as a sample light. Since the reference mirror 10 is oscillated in the direction of othe optical axis at a high speed, interference fringes disappear practically and the surface of the sample 8 is observed distinctly.
