Title: Assembly method for solid-state image pickup device
Inventor: AMAKASU MIKIO
IPC: H04N5/335
Filed: 2002-04-30
Abstract: <P>PROBLEM TO BE SOLVED: To set a lens assembly firmly on a circuit board.  <P>SOLUTION: Multiple circuit boards 1 for a camera are set in orderly positions on a multi-circuit base board 10 with through holes 10a and 10b. The part on the multi-circuit base board 10 except the portions of the circuit boards and the through holes is a remaining portion 10c. The circuit boards 1 are installed successively with the remaining portion as a unit by bridges 10d which partially close the through holes. A solid-state image pickup device 2 is mounted on the circuit board, and the lens assembly 3 is fixed with an adhesive. The lens assembly is provided with leg portions 7a and 7b, which are fixed on the remaining portion 10c with a photosetting adhesive, while the lens assemblies are fixed on the circuit boards with a thermosetting adhesive. As a cure rate of the photosetting adhesive is higher than that of the thermosetting adhesive, the photosetting adhesive is cured first to fix the lens assemblies on the base board. Then, the thermosetting adhesive is cured slowly to fix the lens assemblies tightly. Finally, the leg portions 7a and 7b are removed from the lens assemblies 3, and the bridges 10d are removed from the circuit boards 1.  <P>COPYRIGHT: (C)2004,JPO

Title: Hydraulic circuit with return line metering valve and operation method
Inventor: STEPHENSON DWIGHT B
IPC: F15B11/00
Filed: 2002-05-02
Abstract: PROBLEM TO BE SOLVED: To provide a hydraulic system for operating machines. SOLUTION: This hydraulic system controls the flow of fluids coming in and out of several functional parts of the machine. Each functional part has a valve assembly in which fluid is supplied to an actuator from a supply source under pressure and is returned to a distribution return line connected to a system tank from the actuator by a return line metering valve. It has several regeneration operation modes in which the fluid discharged from one port is supplied to the other port of the same actuator for removing or reducing an amount of hydraulic fluid supplied from the supply source. In several regeneration modes, the fluid inputted into the actuator is obtained from the other hydraulic functional part through the return distribution line.  In these regeneration modes, an electronic control part operates the return line metering valve to restrict the fluid flowing into the tank from the distribution return line so that the fluid is supplied into the actuator port.

Title: Gas cleaning method for deposited-silicon film forming device
Inventor: HABUKA HITOSHI
IPC: C23C16/44
Filed: 2002-05-10
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that, though a gas cleaning step can improve the productivity of semiconductor crystals by shortening the time required for performing the step as much as possible, the possibility of finding out a new gas composition is small and, when a chemical reaction is caused at a high temperature so as to increase the rate of the reaction, devices and members are corroded and contaminants are produced.  <P>SOLUTION: In a gas cleaning method for deposited-silicon film forming device, a silicon film caused to deposit on the surface of the supporting base of a silicon semiconductor substrate is removed at the time of causing a silicon film to deposit on the substrate. At the time of removing the silicon film deposited on the surface of the supporting base, the film is etched off by using a hydrogen chloride gas at a concentration of 85-100% after the temperature of the supporting base is raised to 1,000-1,200°C. It is preferable to raise the temperature of the supporting base while the internal pressure of the reaction chamber of the film forming deice is maintained at 1 atm after the silicon semiconductor substrate having the deposited film silicon film is taken out of the reaction chamber in a state where the internal pressure of the reaction chamber is 1 atm.  <P>COPYRIGHT: (C)2004,JPO
