Title: Construction method for applying lining repairing to inner surface of pipe
Inventor: KOGA MOTOYUKI
IPC: B05D7/22
Filed: 1988-06-08
Abstract: PURPOSE:To substantially reduce a working time to almost 1/4 by a method wherein passages for performing the filling of a resin group and the supply of compressed air toward the end opening parts of an existing piping are respectively provided to the intermediate point of the repairing section of the existing piping to be subjected to lining so as to communicate with said existing piping. CONSTITUTION:Pits F, C, D are formed to the intermediate point M of the repairing section of a branch pipe A and both ends of said pipe A and three passing holes are formed to the upper surface of the branch pipe A exposed to the pit F and pipelines 27, 28 are connected to the passing holes provided on both sides while a rubber ball filling machine 30 is connected to the central passing hole. Receivers 35 are connected to both end opening parts of the branch pipe A in the pits C, D and receiver tanks 36 receiving an excessive resin are connected thereto. Then, the intermediate point M is filled with a rubber ball by the machine 30 to be blocked. In this state, the resin lining to the inner surface of the branch pipe A from the intermediate point to both opening ends through the pipelines 27, 28 is performed. By this method, a lining time is reduced to about 1/4 as compared with a method performing lining starting from one end of the branch pipe A.

Title: Multi-tubular type heat exchanger core and its manufacture
Inventor: HASHIGUCHI TAKASHI
IPC: F28F9/18
Filed: 1994-05-31
Abstract: PURPOSE:To perform an easy and positive brazing operation by a method wherein a raising flange is arranged at a hole connected to a pipe at an end plate of a core of a multi-tubular type heat exchanger so as to make a rigid connection with the pipe and at the same time when the core is manufactured, a brazing is carried out in a furnace while the pipe is raised up and brazing material is installed in such a way that the brazing material flows from an upper part between the pipe and the raising flange. CONSTITUTION:Raising flanges 15, 21 are arranged in holes 14, 20 of end plates 3, 4 of a heat exchanger core 1, and an end part of a pipe 2 is fitted. When a brazing is carried out, brazing material is placed at a base part of the raising flange 15 and a position of a stepped part 17 of a bead 16 so as to assemble the end plates 3, 4 and the pipe 2, and they are brazed in the furnace while the raising flanges 15, 21 are directed downwardly. Since the brazing material flows down directly below a contact surface between the end part of the pipe 2 and the raising flanges 15, 21, the brazing can be easily and positively carried out.

Title: Bias voltage applying apparatus for avalanche photodiode
Inventor: FURUKAWA HIROYUKI
IPC: H01L31/10
Filed: 1984-07-10
Abstract: PURPOSE:To allow an avalanche photodiode (APD) to operate constantly with a certain high sensitivity independently from temperature variations, by utilizing the self-bias method with a combination of a differential amplifier and a light- emitting diode. CONSTITUTION:Signal light 1 is collected by an optical system to the light receiving surface 3 of an APD2. A light emitting diode 4 is disposed at a position where it does not obstruct the signal light 1, the diode having emission spectrum in the wave range where the APD has sufficient spectral sensitivity. This diode is caused to emit light by an output from a differential amplifier 5 for amplifying the difference in potential across a bias resistance 7, whereby bias light 6 is applied to the APD light receiving surface. To the APD2, a bias voltage is applied from a bias power source 9 which has a voltage larger than the maximum breakdown voltage in a range of environmental temperatures used, through the bias resistance 7 and the output resistance 8. An output signal 11, which has been photoelectrically converted, is taken out from the APD through a coupling capacitor 10.

Inventor: OKADA KUNIO
IPC: B28D1/14
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To fix a drill header of a core drill positively to the optional height of a support. SOLUTION: A stopper 31 provided with teeth 29 to be meshed with a rack 23 of a support 22 is connected to the end of a dial shaft 27. An engaging member 33 is integrally formed at the dial 26, and the engaging member 33 is brought into elastic contact with a cam 34 integrally formed at a header machine frame 32, by the action of a coil spring 30. When the dial 26 is rotated to switch into a lock position, the engaging member 33 is engaged with a low lift part of the cam 34 so as to move the stopper 31 forward and to mesh the teeth 29 with the rack 23, thus putting a drill head 21 in a fixed state. When the dial 21 is switched into a free position, the engaging member 33 is engaged with a high lift part of the cam 34 so as to retreat the stopper 31 and to detach it from the rack 23.

Title: Reading system for image for printed circuit board inspecting apparatus
Inventor: UEMURA HARUO
IPC: G01N21/956
Filed: 1990-05-30
Abstract: PURPOSE:To detect the respective images of a wiring pattern and a through hole in a printed circuit board simultaneously and accurately by differentiating the wavelength of a first light for vertical illumination and that of a second light for transmissible illumination from each other. CONSTITUTION:A red light from a light source 110 for vertical illumination is reflected on an area AR to be computed. Part of an infrared ray from a light source 120 for transmissible illumination, which is directed toward a through hole 25, is transmitted through a through hole 25. These reflected and transmitted lights turn to be a composite light overlapping each other spatially and this light falls on a cold mirror 150 through an imaging lens system 140. Accordingly, the red light (a reflected light LR from the surface of a printed circuit board 20) contained in the composite light is reflected on the mirror 150 and imaged on the light-sensing surface of a CCD linear image sensor 161. Besides, the infrared light (a transmitted light LT through the through hole 25) contained in the composite light is transmitted through the mirror 150 and imaged on the light-sensing surface of a CCD linear image sensor 162.
