Title: Extrusion molding of tube
Inventor: NOMURA TATSUO
IPC: B28B3/20
Filed: 1988-10-19
Abstract: PURPOSE:To contrive to heighten the airtightness of tip part and to improve the yield by products by a method in which while a rounding mold is rotated at a prescribed speed, the air-extraction from the rounding mold is achieved at the position spaced apart from its rotating axis. CONSTITUTION:Body 13 is continuously sent into the nozzle 12 of the extruding machine with a core by a screw, and is molded into a tubular shape. When a molded object is extruded form the nozzle 12, the molded object 14 is cut at the exit of the nozzle 12. While the rounding mold 15 molding the bowllike tip of a protective tube with the core 11, is continuously set at the tip of the nozzle 12, the rounding mold 15 is rotated around the axis of the nozzle 12 in the range of 5-20rpm, and the body 13 containing air is discharged from the air-extracting hole 15a spaced apart from the rotation axis of the rounding mold 15. Then, while the body 13 is sent therein by the screw, the rounding mold 15 is synchronously moved with this sending speed and is separated from the nozzle 12, and then the tube part 16b connected to the bowl part 16a is extrusion-molded. Consequently, the bubble or flow line on the tip of the molded object is reduced, and the airtightness of the tip part is improved, whereby the yield of the product is heightened.

Abstract: PROBLEM TO BE SOLVED: To prevent the interference of transmission radio waves from plural route buses by operating a display part in receiving the radio waves of a frequency matched with the frequency allocated to a present stop from the route bus at respective bus stops. SOLUTION: When a controller 13 instructs the frequency to be used on the basis of a frequency number for bus approach signals received from a voice guidance device 14 through an RS232C interface 16 to a transmitter 12 in the form of a character code, the transmitter 12 transmits the radio waves on which the bus approach signals are superimposed from an antenna 11 by using the frequency instructed from the controller 13. The receivable frequency is determined beforehand for the receiver 22 of the bus stop 2, and when the receiver 22 receives the bus approach signals from the route bus 1 by the radio waves of the frequency allocated to itself, it transfers the received contents to a control part 23. Then, the control part 23 analyzes the bus approach signals and lights the display lamp of the pertinent preceding display of the display part 24.

Title: Air-conditioning device
Inventor: TAGASHIRA HIDEAKI
IPC: F25B47/02
Filed: 1988-10-19
Abstract: PURPOSE:To prevent the returning phenomena of liquid into a compressor and permit defrosting operation by switching a three-way switching valve while setting a four-way switching valve at the position of space heating mode as it is by a method wherein heat exchange between the heat of one part of high-temperature high pressure gas refrigerant from the compressor and the heat of a suction side pipeline for the compressor is effected through a suction heat exchanger. CONSTITUTION:Defrosting operation is permitted in a condition that fans 8, 9 for ventilating indoor side and outdoor side heat exchanger 6, 3 while setting a four-way switching valve 2 at the position of room heating operation as it is are stopped and a three-way switching valve 13 is switched to open a fourth bypass circuit 14. Upon such defrosting, heat loss for switching the four-way switching valve 2 may be eliminated. On the other hand, low- temperature liquid refrigerant does not pass through the indoor side heat exchanger 6 and, therefore, the outflow of cold air into a room may be prevented, the inner diameter of a pipeline 15 may be made smaller than the same of a delivery side pipeline 16, the capacity of a compressor 1 may be increased since an input is increased and a time for defrosting may be shortened. On the other hand, heat exchange between the heat of a suction side piepline 1a for the compressor 1 and the heat of high-temperature high-pressure gas refrigerant, discharged out of the compressor 1, is effected through a suction heat exchanger 11 whereby the returning phenomenon of liquid into the compressor 1 may be prevented.

Abstract: PURPOSE:To enable extremely accurate shape discrimination by using the array of many lenses which are arranged at intervals while having their optical axes in parallel as a Fourier transforming lens. CONSTITUTION:Many images 20 in unknown shapes are formed at positions corresponding to respective lens parts 11B.... Then a reproduction surface 21 is radiated with coherent parallel light 4 from behind to illuminate the respective images, which are formed on the focal plane 5 of the lens array body 11 through an image forming lens 3. This image is incident as individual Fourier- transformation processed images on a matched filter array 8 through the individual lens parts 11B.... When this incident image conforms with a specific image written in the matched filter array 8, a collation beam 9 is generated at the image place. The beam 9 is converged by a lens 22 and light-received by a two-dimensional image pickup element 23 to know which matched filter on the filter array 8 the image has collation with, thereby recognizing the unknown shape 20.

Title: Electric circuit board
Inventor: NAITO KAZUMASA
IPC: H01B1/22
Filed: 1987-10-20
Abstract: PURPOSE:To improve solder wettability and adhesion, by dispersing silver powder, rhodium powder and/or organic rhodium compound in a vehicle, and baking a conductor composition, which includes antimony oxide as an inorganic binder and does not include glass frit on a glass or low-temperature baked ceramic board, so as to cover the board. CONSTITUTION:Metal powder, i.e., silver powder, rhodium powder and/or organic rhodium compound or metal powder comprising silver powder, platinum powder, rhodium power and/or organic rhodium compound is dispersed in a vehicle in a conductor composition. A glass or low-temperature baked ceramic circuit board is covered with the conductor composition. At this time, antimony oxide is included in the conductor composition as an inorganic binder and glass is not substantially included. Even if the glass is not substantially included in the conductor composition, the glass is diffused into the conductor composition in the circuit board during the baking. Thus sufficient adhesive strength is secured between both parts. Since the glass is not substantially included in the conductor composition, the solder wettability of the circuit board is remarkably improved.

Title: Homocentric optical system
Inventor: KENNO KOKICHI
IPC: G02B27/01
Filed: 1993-10-22
Abstract: PURPOSE:To provide a homocentric optical system which is flat and hardly generates an aberration, and capable of photographing and observing a clear image by providing each of semi-transmitting reflecting surfaces so that it performs at least one beam transmission and at least one beam reflection. CONSTITUTION:When the pupil position is 1, the semi-transmitting reflecting surface of a first face is 2, the semi-transmitting reflecting surface 3 of a second face is 3, and an image face is 4, a homocentric optical system has at least two semi-transmitting reflecting surfaces 2, 3 having the curvature centers near the pupil whose concave faces are turned on the pupil side. Each of the semi-transmitting reflecting surfaces 2, 3 is arranged so that is performs at least one beam transmission and at least one beam reflection. Since the pupil face 1, the curvature center of the first face 2, and the curvature center of the second face 3 are coincident with each other, both the axial beam and the non-axial beam are rotation-symmetric with the pupil position 1 as the center. This means that astigmatism and comatic aberration which are non-axial aberrations never occur. Since it is all the reflecting faces that have refracting power, no chromatic aberration occur in principle. Occurrence of spherical aberration is almost ignorable.
