Abstract: PURPOSE:To prevent the breakaway of lining and the leakage of fluid by pressing the both ends of a metallic pipe inserted into a branch pipe against the inside surface of the branch pipe and the peripheral edge of a through hole provided for the lining, and filling sealed space formed therein with synthetic resin. CONSTITUTION:In such a structure that a main pipe 1 whose inside surface is fitted with lining 3 is provided with a branch pipe 2, a through hole 4 is provided for the lining 3 at a position where the branch portion from the main pipe 1 is formed. A metallic pipe 5 is inserted into the branch pipe 2 and its end area is engaged into the through hole 4. And the both end parts of the metallic pipe 5 are expanded in its radial direction, so as to be pressed against the inside surface of the branch pipe 2 and the peripheral edge of the through hole 4 via packings 6, 7. Then sealed space 16 enclosed with the branch pipe 2, the metallic pipe 5 and the lining 3 is therein formed, and reaction hardening synthetic resin 8 is applied to the space and solidified therein. As a result, there is no possibility that fluid enteres between the lining and the main pipe, and the leakage of the fluid can be prevented.

IPC: H01L31/10
Filed: 1991-05-21
Abstract: PURPOSE:To provide a semiconductor device which varies electron mobility with light used for photodetectors, photogate transistors, and the like. CONSTITUTION:A semiconductor substrate 1 is overlaid with a channel area of quantum well structure and a semiconductor cap layer 10.

Filed: 1987-06-10
Abstract: PURPOSE:To obtain the high storage keeping capacity from the irradiating ultraviolet rays by a method wherein an ultraviolet ray absorber is provided inside an ultraviolet ray shielding structure. CONSTITUTION:An ultraviolet ray absorber 8 comprising e.g., polysilicon is formed encircling a floating gate 5 on a field oxide films 12 formed between a drain region 1 and a source region 3 through the intermediary of insulating films 13. In other words, any permeating ultraviolet rays are going to reach the floating gate 5 of a floating gate type MOS(FAMOS) while repeating irregular reflections passing through the field oxide films 12 and the insulating films 13 as the permeating channels but considerable level of permeating ultraviolet rays is absorbed by the ultraviolet ray absorber 8 provided halfway on the channels. Through these procedures, the permeating ultraviolet rays originally in minor level are further reduced so that the ultraviolet rays reaching the floating gate 5 may be notably attenuated to prevent the storage contents from being erased.

Title: Frame synchronizing system
Inventor: HONGO YOSHIYUKI
IPC: H04L7/08
Filed: 1986-06-20
Abstract: PURPOSE:To quickly restore a synchronized state when a pseudo synchronizing state is set, by counting synchronization error pulses and forcibly clearing a synchronization protecting circuit when the pulses are counted more than the prescribed number of times within a fixed time. CONSTITUTION:Frame synchronizing error pulses in a pseudo synchronizing state are inputted to a synchronization protecting circuit 10 and counting means 12. When the count value of the synchronizing error pulses of the counting means 12 exceeds a set value in a prescribed time fixed by a timer 14, a signal is outputted to a synchronization protecting circuit clearing means 16 to forcibly clear the circuit 10 so as to set a hunting state again and a synchronizing state is restored. Since the circuit 10 has a prescribed number of protecting stages, the re-hunting state is not set unless the synchronization error pulses are continuously inputted for the prescribed number of times and a state where the pseudo synchronizing state is continued for a long time may be occurred. In order to prevent the occurrence of such state, the re-hunting state is forcibly set by means of the above-mentioned circuits so that the synchronizing-state can be quickly restored.

Abstract: PURPOSE: To synthesize hydrous iron oxide consisting of high-quality goethite essentially at a low cost, by oxidizing a suspension consisting of iron (II) hydroxide with a gaseous oxidizing agent and a liquid oxidizing agent together.  
     CONSTITUTION: A suspension consisting of iron (II) hydroxide is oxidized with a gaseous oxidizing agent, e.g. air, and a liquid oxidizing agent, e.g. NaClO 3 , together, and the liquid oxidizing agent is preferably used in the initial stage of the reaction and then changed over to the gaseous oxidizing agent to carry out the oxidation. In the process, the suspension is reacted at 30W60°C with agitation. After the suspension turns yellow completely and the reaction is completed, a formed precipitate is washed with water, filtered and dried to give goethite powder in the form of fine needlelike crystal. According to the method, the amount of the liquid oxidizing agent of comparatively high price is reduced to half or less that in the case of the liquid oxidizing agent used throughout the reaction period, and the raw material cost can be saved.
