Title: Manhole made of synthetic resin and construction method thereof
Inventor: KUBO YOSHIO
IPC: E03F5/02
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To reduce the weight of a manhole so as to be transportable by manual force and ensure strength after construction by installing the manhole in a specified position, and then pouring an inorganic filler into a hollow part and hardening it. SOLUTION: A bottom plate 2 is disposed at the bottom part of an excavated hole, and a lower layer unit 3 is disposed on the bottom plate 2 and bolt-fixed to the bottom plate 2. In this case, the wall of the lower layer unit 3 is made lightweight by hollow structure so as to be transported and installed by manual force. An inorganic filler M is then filled in a hollow part from an opening part of the lower layer unit 3, and a middle layer unit 4 is stacked before the filler M is hardened. In this case, a fitting protrusion of the middle layer unit 4 is fitted into the opening part, and two units 3, 4 are rigidly fixed to each other by hardening of the filler M. The wall of the middle layer unit is made lightweight by hollow structure. The required number of middle layer units 4 are stacked in the same way and fixed by mortar in the hollow part.  An upper layer unit 5 is then fixed, the filler is filled, and a cast iron cover 6 is placed thereon. Sufficient strength can therefore be obtained.

Title: Manufacture of semiconductor device
Inventor: KUDO NOBORU
IPC: H01L21/3205
Filed: 1987-03-26
Abstract: PURPOSE:To realize direct contact and to improve IC integration density, by making a polycide wiring continue a Si substrate via silicide. CONSTITUTION:After PolySi 4 is piled on an oxide film 3 by a chemical vapor growth method, a resist 5 is used as a mask to etch the oxide film 3 and the PolySi 4 on a N<+> diffusion layer 2 on a surface of a Si substrate so as to form a contact hole. Next silicide 6 such as WSi2 is piled on the PolySi 4. Next a resist pattern is used as a mask to pattern the silicide 6 and the PolySi 4 by an etching method, so that a polycide wiring is formed. Since the N<+> diffusion layer 2 is made to continue to the polycide wiring via the silicide 6, contact resistance becomes small and the dispersion of values of resistance becomes small. Hence, direct contact of the polycide wiring and the Si substrate can be realized and so integration density can be improved.

Title: Radio base station
Inventor: IIMORI KATSUMASA
IPC: H04W56/00
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To surely secure the synchronization among plural base stations, which transmit the adjacent data by comparing the synchronous code that matches with a prescribed synchronous code pattern with the identification signal to be received next and transmitting a signal to start a detection job, if the matching is confirmed between those code and signal. SOLUTION: A demodulation part 1 receives the reception data and demodulates these data to serially output them to a synchronous word detection part 2a, a 42-bit shift register 18 of a non-reception decision part 5 and a receiving RAM 4 respectively. A 32-bit shift register 7 of the part 2 compares the bit data equivalent to 32 bits obtained by shifting, in sequence the inputted reception data by each bit from the head of the data with the fixed value of a 32-bit unique word via a comparator 8. When both input data of 32 its mutually match, a matching pulse is outputted to an AND circuit 81 placed on the next stage of the comparator 8 together with a unique word detection pulse. Thus, synchronization with plural base stations is surely secured.

The zoom lens is thereafter zoomed at a low speed in the telephoto direction. The motor 10 is stopped when the change of the detection valve of the zoom encoder 9 by +1 is confirmed. The backlash of the mechanical system is thereby prevented and the zoom lens is stopped always at the target position.

Title: Liquid crystal display element
Inventor: TESHIROGI TOSHIYUKI
IPC: G02F1/133
Filed: 1987-03-27
Abstract: PURPOSE:To suppress shrinkage and deformation of glass substrates by forming electrodes on the glass substrates subjected to preliminary calcination and forming a liquid crystal cell at the time of preparing a liquid crystal display element. CONSTITUTION:A difference from the conventional liquid crystal elements lies in that the glass subjected to the preliminary calcination is used for the large glass substrate 4 and small glass substrate 5 constituting the liquid crystal cell 2. More specifically, the prepn. of such liquid crystal display element 1 is executed by first subjecting the glass substrate 14 for multiple-pieces production to the calcination for about 20-40min at about 500 deg.C and, therefore, the internal strains and micropores, etc., in the glass substrate 14 are partially sintered and removed. The shrinkage and deformation of the substrates 4, 5, 14 are consequently suppressed even if the substrates are exposed to a high temp. Troubles such as defective display occurring in the shrinkage and deformation are thereby eliminated. The shrinkage and deformation of the glass substrates are suppressed as well even if various members are formed on the glass substrates by a method entailing heating means at the time of production.

Title: Absorption type hot and chilled water generator
Inventor: FUJIKURA KIKUTARO
IPC: F25B15/00
Filed: 1991-03-14
Abstract: PURPOSE:To stabilize the circulation of absorption liquid by branching a refrigerant vapor pipeline communicated with a high temperature regenerator, opening one branched line to a condenser by way of a low temperature regenerator and a valve and the other branched line to the condenser by way of a valve alone and communicating the high temperature regenerator inlet side of an intermediate liquid pipeline with a pump inlet side of an enriched liquid pipeline by way of a valve-equipped absorption liquid pipeline in terms of a double effect absorption refrigerator. CONSTITUTION:When solenoid valves V1 and V3 are opened while solenoid valves V2 and V4 are closed, cooling operation will be carried out in standard double effect mode. On the other hand, when the solenoid valves V1 and V3 are closed while the solenoid valves 2 and 4 are opened, a pump 5 will feed an intermediate liquid discharged from a high temperature regenerator 1 to an absorber 5 by way of an intermediate liquid pipeline 14, the solenoid valve 4 and a low temperature heat exchanger 7, which eliminates resistance troubles of the heat exchanger. The refrigerant vapor generated in the high temperature regenerator 1 is directly fed into a vaporizer 3 by way of the valve 2 to heat a water pipeline 31. Since the absorption liquid of the absorber 5 is heated when the refrigerant vapor is absorbed, this construction enhances thermal efficiency and functions as a single effect heat pump.

Title: Optical adapter
Inventor: TAKAMATSU MICHIHIRO
IPC: G02B6/38
Filed: 1995-03-30
Abstract: PURPOSE: To make it possible to prevent the failure of a sleeve generated at the time of inserting an optical connector into an optical adapter and to execute optical coupling with high reliability by adopting the constitution in which the front end of a ferrule is inserted into a sleeve in the state that the attitude of the ferrule is once controlled by an introducing wall. CONSTITUTION: A sleeve holder 13 is opened to a taper shape and is provided with the introducing wall 15 integral with an optical adapter body 11 within its opening side. The insertion attitude of the ferrule is so controlled as to be aligned to an axial direction by the introducing wall 15 when the ferrule of the optical connector is guided by the taper of a sleeve holder 13 and is advanced into the opening. Some inclination of the ferrule is permitted in this state but the inclination of the central axis of a through-hole 14 and the ferrule is made slight by the effect of the introducing wall 15 when the ferrule advances further into the inside and its front end is fitted into the sleeve 16.  An excess stress is not applied on the opening end of the sleeve 16 in the direction perpendicular to the axial direction in this state and, therefore, the failure and breakage of the sleeve 16 do not arise.
