IPC: F28D7/02
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To provide a compact heat-exchanging device that has a coil-shaped pipeline and high heat exchange capability. SOLUTION: First and second cylindrical channels 21 and 22 are composed of a cylindrical chiller drum 10 and external and internal shells 13 and 14, and a cooling pipe 6 being wound in a coil shape is installed inside.

Title: Welded-state detecting apparatus
Inventor: MORI KIYOKAZU
IPC: B23K26/00
Filed: 1991-09-09
Abstract: PURPOSE:To make it possible to perform uniform welding all the time by detecting the sound or the light from a welded point, comparing the magnitude and the fluctuating width of the signal level with the preset values, judging the good or defective state of the welding, and changing the welding conditions when the result is defective. CONSTITUTION:After the start of welding, high-luminance plasma 26 is generated with a welded point 25 as the center. The light is detected with a detector 23. The detected signal is inputted into an amplifier 31 through a filter 30. The signal, which becomes the specified level, is digitized with an A/D converter 32 and inputted into a control computer 33. When the welding is performed normally, the waveform having the high signal level is continuously detected. When the waveform is located in the vicinity of the limit, the signal, whose level fluctuation is intense is detected. When the welded state is completely inadequate, the signal at the low level is detected. These states are discriminated with the computer 33. When the defective welded state is detected, the output of a laser oscillator 5 is increased or the feeding of wire 20 of a wire feeding device 21 is controlled with the computer 33. Thus the welding conditions are changed.

Title: Surface acoustic wave filter
Inventor: FUJII YOSHIMORI
IPC: H03H9/64
Filed: 1989-09-01
Abstract: PURPOSE:To obtain a satisfactory filter characteristic by setting an intersection width weighting inter-digital transducer electrode including a dummy electrode to be split constitution and forming a part including a part of the terminal electrode of said electrode in a check pattern. CONSTITUTION:The electrode finger part of the intersection width weighting inter-digital transducer electrode 3 forms the width of fingers to be lambda/8, and the detached intervals of adjacent fingers to be lambda/8 so as to split them. Thus, a reflected wave generated except for the terminal electrode 3a can be eliminated as a vector sum 0 in said part. Then, the part including a part of the terminal electrode 3a can be formed in the check pattern. Consequently, the phases of the reflected waves from both electrode parts become reverse and the reflected waves generated from the terminal electrode 3a can be eliminated by setting the width and the detached intervals of the electrode in the check pattern to be lambda/8 which is the same as those of the electrode fingers in split constitution in the direction of the travel of a surface acoustic wave. Thus, the satisfactory filter characteristic can be obtained.

Title: Optical picture input device
Inventor: ASAI TAKAHIRO
IPC: G06K9/20
Filed: 1984-10-30
Abstract: PURPOSE:To expand the readable extent (number of picture elements) of an object without increasing numbers of both light source and lens, by making the set position of a lens which converges lights from an infrared light emission diode changeable and changing the focal point of the infrared light emission diode on individual objects. CONSTITUTION:Infrared rays irradiated from infrared light emission diode 1 are converged by a lens 2 and form an image on the surface of an object 3. Intensity of their reflecting lights at the focal point changes depending upon the object 3 whether it is black or white and a photosensor 4 receives the reflecting lights. The signal of the photosensor 4 is processed at an interface circuit 5 composed of a microcomputer, etc., and thus, the black and white of the object is detected. The infrared light emission diode 1 emits lights in order and a position on the object can be detected on the basis of information indicating which infrared light emission diode emits lights. Therefore, more information can be obtained from the object than in the case where the lens 2 is fixed when the lens 2 is mechanically inclined, without increasing numbers of the infrared light emission diode 1 and lens 2.

Title: Antenna system
Inventor: KIYONO KIYOHARU
IPC: H04B1/58
Filed: 1985-10-14
Abstract: PURPOSE:To prevent impedance fluctuation of an antenna viewed from transmitter/receiver sides and to avoid a transmission signal reflected from the antenna from being returned to the transmitter/receiver by using an 4-terminal circulator and a switch. CONSTITUTION:In case of transmission, a switch 7 is opened. A signal outputted from a transmitter 1 is fed to an antenna 4 via a circulator 5. The signal reflected from the antenna 4 is absorbed by a terminator 6. As a result, the impedance viewed from a transmitter output terminal 1a toward the antenna 4 is always constant. On the other hand, in case of the reception, the switch 7 is closed. Then the reception signal made incident from the antenna 4 enters the receiver 2 through the circulator 5 and the switch 7. In this case, the impedance viewed from the receiver 2 toward the antenna 4 is always equal to the impedance of the terminator 6. Thus, the noise figure of the receiver is kept constant regardless of the fluctuation of the antenna impedance viewed from the antenna 4a toward the antenna 4.
