Title: Portable gas detector
Inventor: MITANI TETSUYA
IPC: G01J1/02
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To detect a gas with a required accuracy by forming a light transmitting part on the front of a body and fixing a supporting member which is telescopic forward from the body, and providing the forward end thereof with a member for reflecting a measuring light from a light source toward the light transmitting part. SOLUTION: A light reflection member 9 is brought to a using position by elongating a bellows 7 and the reflecting face 9a is directed toward the light transmitting window 3b on the front end face 3a of a body 3. An incandescent light at a measuring light source section is then lightened and a chopper is switched to emit a pulse measuring light forward of the body 3 through the window 3b and a light reflection film 15h in a small chamber 15f is irradiated with the probe light from a light source 15r of a Golay cell 15. The measuring light passes through a space to be measured and the wavelength components in near infrared region are absorbed depending on the gas concentration. Subsequently, it is reflected on the reflecting face 9a back to the window 3b thence passes through a light transmission window 15d before impinging on a light receiving face 15g.  Xe gas in the small chamber 15f expands depending on the quantity of received light and a corresponding variation of the film 15h is outputted at the period of measuring light from an amplifying circuit 15x, Gas in the space to be measured is detected based on variation of the film 15h and indicated.

Inventor: OZORA SHIGERU
IPC: H01L21/60
Filed: 1986-07-29
Abstract: PURPOSE:To maintain connection strength and to prevent the destruction of an element by reducing the pressure to a thermocompression bonding jig by providing such a jig for connecting a plurality of bump electrodes with a plurality of external electrodes in a plurality of steps. CONSTITUTION:Many bump electrodes 13 are provided around a semiconductor element for a lead electrode. After an external electrode 14 which makes a pair with the bump electrode 13 is positioned to the bump electrode 13, the bump electrode 13 on the one side of the semiconductor element and the external electrode 14 positioned to the bump electrode 13 are connected by a thermocompression bonding jig 15. Then, the position and the direction of the bonding jig are changed and the bump electrode 13 on each side of the semiconductor element and the external electrode 14 are connected in sequence. For example, all the connections are finished in four processes since the bonding jig 15 can connect four positions simultaneously. The load of the bonding jig is reduced since all the connections are finished in approx. 1/(dividing number) in this way.

Abstract: PURPOSE:To eliminate erroneous diagnoses owing to faults or defective mounting of sensors and to perform diagnosis always accurately by constituting a diagnosing device in such a way that the sensors are self-diagnosed prior to diagnosing of the functions of automobiles. CONSTITUTION:12 is a storage device for contents of self-diagnoses which stores beforehand the inspecting steps and items for the self-diagnoses of sensors, and 13 is a storage device for the reference values of the self-diagnoses which stores beforehand various kinds of reference values that are references for the self- diagnoses. When an engine is started and assumes an idling state, a control unit 9 reads out the inspection contents of the self-diagnoses stored in the device 12 and performs the control complying with said contents. The signals of the respective sensors in a sensor group 2 are taken into the control unit.
