Title: Variable dummy load
Inventor: TATSUTA MASATAKA
IPC: H01L29/73
Filed: 1978-11-30
Abstract: PURPOSE: To provide a variable dummy load by utilizing drain allowable loss of power FET to control voltage.  
     CONSTITUTION: A FET element Q 1  in which the drain current IDS does not saturates against the drain-to-source voltage VDS is used so that the change in gate voltage VGS allows a desired characteristics to be selected to meet the requirements of the test device. Such FET has a high input impedance and needs a very small power for controlling the gate. This allows a simple control circuit GVC in which the varistor RV regulation can provide a continuously variable resistance from less than 1Ω to several ten kΩ. Furthermore, FET high speed switching performance can be utilized in practical applications ranging from direct current to about 5MHz.

Abstract: PURPOSE:To continuously measure the gas content of a gas-containing sealing package in non-contact manner, quickly and with a high accuracy by detecting the temperature distribution of the top face of the gas-containing sealing package through a detecting element arranged in the vicinity of a mounting table for mounting the gas-containing sealing package to operate the gas content. CONSTITUTION:A detector 211 is arranged above the intermediate part of the carrier path of a conveyor 101 and the temperature of the surface of a gas-containing sealing package A is detected by infrared rays radiated from the gas-containing sealing package A on the conveyor 101. In this detector 211, a circuit 20 for converting obtained temperature information into heat-image data and detection means 40 for detecting the area of the part of a predetermined temperature range are successively connected with a determination circuit 50. When the temperature range area is within the predetermined range, the gas-containing sealing package A is judged by the determination circuit 50 to be a non-defective in which the content of gas is within a predetermined range. Also, when the area is not in the predetermined range, the package is judged to be a defective. Thus, it is possible to continuously measure the gas content of the gas containing sealing package in non-contact manner, quickly and with a high accuracy.

Abstract: PROBLEM TO BE SOLVED: To execute signal transmission of high speed between a measuring board and a semiconductor to be measured without using a jig by electrically conducting a conductive pad to a measuring pattern through a linear material packed inside a through hole. SOLUTION: A through hole is formed on a measurement board corresponding to a measurement point 5 (soldered bump) of a semiconductor to be measured 1. For example, a conical conductive pad 6 is mounted on the side of the semiconductor 1 to be measured of the through hole, a linear material 7 made of a conductor is packed inside the through hole, and the conductive pad 6 is electrically conducted to a measurement pattern through the linear material 7. The conductive pad 6 and the linear material 7 are made of gold. By applying this structure, as a top part of the through hole is sealed by the conductive pad 6 to obtain the function of a socket, and the measuring jig is not used, an excess contact point does not exist between the semiconductor 1 to be measured and the measurement board, and the electric length can be shortened.  Whereby the signal delay in the high-speed measurement of semiconductor product can be prevented.

Title: Focal point adjusting mechanism for camera
Inventor: TAMURA SHIYUUICHI
IPC: G02B7/28
Filed: 1977-12-09
Abstract: PURPOSE: To facilitate and ensure the interchange from the automatic focusing operation to the  manual focusing operation by maing it possible to detect the focal point of the optical system of a  camera only when the range is to be set.  
     CONSTITUTION: Upon the automatic focusing operation, a ball is pushed into a notch 1a to fix  a range finding ring 1 so that a range adjusting member 6 is turned through a charge member  20, which is made coactive with a film winding lever 28, and through a pin 24 thereby to effect  the charge with a spring 5. The member 6 has its projection 6a abutting against the leading end  portion 9a of a fixing lever 9. The retention of the member 6 is released by the lever 9 when  a shutter button 29 is depressed so that the lens is moved to effect the automatic focusing  operation in accordance with the found range by the member 6 through an automatic detecting  circuit which is then energized. On the other hand, if an interchanging switch 12 is shifted to  the automatic focusing operation, the retention of the member 6 by the lever 9 is not accomplished so that the lens is moved in response to the range finding operation which is effected by  the manual rotations of the member 6. As a result, so long as the range is not found, the focusing operation is not effected for both the automatic and manual operations. During the automatic  focusing operation, the interchange to the automatic one can be effected to correct the focusing  operation.
