Title: Fitting structure of curtain wall panel
Inventor: TANAKA YOSHIHARU
IPC: E04B2/88
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To surely prevent a bolt from being loosened by the repetitive inter- layer displacement of a building by filling an adhesive in a screw section between a screw hole on a curtain wall side and the fitting bolt, and integrating the screw section with the adhesive. SOLUTION: A loose hole 10 for following the inter-layer displacement is arranged on the upper vertical plate section 3b of a fastener 3, and a plate nut 11 is welded to the lower section of the back face of a curtain wall panel 1. An adhesive 17 is applied to the inside of a screw hole 11a, the surrounding region and the screw section of a fitting hexagon bolt 12, and the hexagon bolt 12 is inserted into the loose hole 10 of the upper vertical plate section 3b via a washer 13 from the building side. The hexagon bolt 12 is screwed and fastened to the screw hole 11a of the plate nut 11, and a screw section between the bolt 12 and the screw hole 11a is integrated by the adhesive 17.  When the lower section of the curtain wall panel 1 repeats the relative movement in the horizontal direction against the inter-layer displacement of the building, the bolt 12 tends to be rotated in the loosening direction, however the adhesive 17 acts to prevent it, and the bolt 12 can be surely prevented from being loosened.

Title: Liquid fuel combustor
Inventor: KITAJIMA SOUICHI
IPC: F23D11/08
Filed: 1979-10-18
Abstract: PURPOSE: To prevent the leakage of fuel and abnormal increase in the burning level by halting the rotation of a fuel pump earlier than the closure of an opening at the tip of a return pipe due to freezing when leaked water is accumulated and frozen in an oil tank.  
     CONSTITUTION: A suction port 4b of a pump is located below a tip opening 26 of a return pipe 25. In operation, a pump impeller 8 fails to rotate due to freezing when water is built up in an oil tank 5 and frozen to close the tip opening 26 of the return pipe 25, which checks the fuel from being fed to start combustion. Consequently, inflow of fuel to be returned to a carbureting chamber 16 eliminates the hazard of enlarged flame in the combustion.

IPC: H01L21/60
Filed: 1991-06-06
Abstract: PURPOSE:To eliminate a connection defect and to enhance the reliability of the title package by a method wherein an inner lead guided to the inside of a resin from an external terminal is curved partly so as to obtain the electrical continuity of the external terminal to an internal element. CONSTITUTION:The title package is composed of the following: inner lead parts 9d in which inner leads for leads 9 are curved partly; and an inner-lead fixation part 11 one part of which has been curved to the same shape as that of the inner lead parts 9d. The leads 9 are expanded and contracted by a change in a temperature and by a high-temperature atmosphere in their soldering operation to a printed wiring board. At this time, a stress is easy to cause strongly in the direction of an arrow A. When the leads 9 are curved partly, one part of the stress is absorbed by curved parts. A stress exerted on the connection parts of bumps 8 on IC electrodes to the inner lead parts 9d is reduced, and a connection defect can be eliminated.

Title: Light-modulation-type process-amount sensor and process measuring instrument using it
Inventor: YODA MASAKI
IPC: G01D5/26
Filed: 1995-06-01
Abstract: PURPOSE: To conduct a multiple-point measurement, reduce the number of continuation cables, and improve noise resistance by providing a piezoelectric vibrator and an oscillation circuit and modulating transmission light or reflection light due to the vibration of the piezoelectric vibrator in response to the fluctuation of the amount of process. CONSTITUTION: A piezoelectric vibrator 2a vibrates by to the application of a voltage. It vibrates periodically so that both surfaces slide mutually in different directions in the case of the thickness slide vibration, thus enabling the position of a pin hole to move in the up-and-down directions for the vibration period from a light axis. When the pin hole deviates from a light axis, light emitted from an optical fiber 5a for transmitting light passes through the pin hole and cannot reach an optical fiber 5b for receiving light. Therefore, the quantity of light which the fiber 5b can transmit is periodically modulated for each 1/2 of the dialing period of the vibrator 2a for the incidence light with a constant quantity of light. On the other hand, the piezoelectric vibrator performing expansion motion also achieves the same effect since the pin hole periodically moves similarly.  Then, an oscillation frequency changes depending on the change in the amount of process in, for example, temperature and pressure to be measured.
