Title: Semiconductor device and production thereof
Inventor: OSAWA TOSHIHIKO
IPC: H01L21/768
Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To prevent generation of dust from a silicon substrate. SOLUTION: This method is provided with a process for removing an inter- layer insulting film 15 located on the outer periphery side of a silicon substrate 10, so that the outer diameter of the inter-layer insulating film 15 can be reduced rather than that of the silicon substrate 10 and a silicon can be exposed on a side surface 28 of the silicon substrate 10. By adding such a process, even if a positioning pin for positioning the silicon substrate 10 is made to contact with the side surface 28 of the silicon substrate 10 in the case of carrying the silicon substrate 10 or performing the surface processing of the silicon substrate, the positioning pin will not make contact with the inter-layer insulating film 15.  Therefore, the inter-layer insulating film 15 can be prevented from being dropped from the silicon substrate 10 by positioning pin contact and dropped broken pieces can be prevented from turning into dust.

Abstract: PURPOSE:To evaluate the detecting characteristic of a photodetector by supplying an intensity instruction to an illuminating means and processing each of a plurality of wavelengths and also each of a plurality of intensities of projecting lights based on an output of a measuring means and an output of the photodetector. CONSTITUTION:A processing means 151 outputs an intensity instruction to set sequentially a plurality of preset intensities of radiating lights to an illuminating means 121. The means 121 radiates the light of the intensity corresponding to the intensity instruction to a spectroscope 131. Moreover, the processing means 151 outputs a wavelength instruction to indicate sequentially a plurality of preset wavelengths to the spectroscope 131, so that the light of the wavelength corresponding to the wavelength instruction is guided to a photodetector 111. As a result, the wavelength and intensity of the light incident upon the photodetector 111 are sequentially changed. The intensity of the light entering the photodetector 111 for each combination of the wavelength and intensity of the light is measured on the basis of the light projected from the spectroscope 131 and accordingly the detecting characteristic of the photodetector 111 can be evaluated.

Title: Intake and exhaust apparatus for four-cycle internal-combustion engine
Inventor: AOI KAZUO
IPC: F02B31/00
Filed: 1984-01-11
Abstract: PURPOSE:To reduce blow-by of intake air at the time of low-speed operation of an engine, by disposing an intake-side valve and an exhaust-side valve opened both at the time of high-speed operation of the engine to correspond to intake ports and exhaust ports which are formed around the center of a combustion chamber in the manner of opposing each other obliquely. CONSTITUTION:At the time of low-speed operation of an engine, an intake-side valve 19 and an exhaust-side valve 20 are both closed, so that most of the intake air passed through a throttle valve 15 is carried to an intake port 6 via a low- speed intake passage 12. Intake air drawn into a combustion chamber 5 from the intake port 6 is burnt, and then the combustion gas is discharged to exhaust passages 16, 17 respectively from exhaust ports 8, 9. Since, at the time of low- speed operation of the engine, the high-speed exhaust passage 17 is closed by the exhaust-side valve 20, the exhaust port 9 connected to the exhaust passage 17 is substantially in the closed state. Therefore, blow-by of intake air through the exhaust port 9 is not caused and swirl of intake air in the combustion chamber 5 is strengthened continuously, so that the combustion efficiency of the engine can be raised.

Filed: 1978-01-17
Abstract: PURPOSE: To provide the subject device wherein triak included in the circuit is consurrently used as a part of a pulse generating circuit, whereby direct lighting is possible from a low-voltage power source by a compact structure.  
     CONSTITUTION: When a power source 4 is turned on, a triak voltage VT is applied to a S element 12 which is a voltage responsive element, through a primary coil 10 and a pulse generating capacitor 11 at the time the triak 5 is non-conductive, thereby making 3S element conductive. By this procedure a current flows to a closed circuit including the power source 1, an inductance 2 and the like to charge the pulse generating capacitor 11. Then, when the triak 5 becomes conductive, a pulse discharge occurs to light the discharge lamp 4. Then, when the discharge lamp 4 is shifted to stationary lighting, the voltage applied to both ends of the pulse generating capacitor 11 coincides with a discharge lamp voltage, and the 3S element becomes non-conductive, and hence the pulse generating circuit stops its operation.

Title: Method for measuring alcohol concentration by using solid electrolyte
Inventor: USUI TOSHIO
IPC: G01N27/41
Filed: 1987-01-13
Abstract: PURPOSE:To measure an alcohol concn. with high accuracy by providing porous electrode to both faces of stabilized zirconia, impressing voltage between the two electrodes and passing the current with the hydrogen ions generated by electrolysis of gaseous alcohol as a carrier. CONSTITUTION:The gaseous alcohol passes a very small gas flow hole 4 of a cap 5 provided on an anode side and arrives at an anode 2 when an alcohol sensor is installed in an inert gas which does not contain oxygen and hydrogen or moisture and contains the alcohol. The gaseous alcohol is electrochemically decomposed by the anode 2 when the voltage is impressed between the anode 2 and cathode 3 at the high temp. maintained by a heater 6. The hydrogen ions formed by the electrochemical decomposition of the gaseous alcohol are migrated from the anode 2 toward the cathode 3 through a solid electrolyte 1 by a so-called ''pumping'' effect; namely, the current with the hydrogen ions as a carrier flows. The alcohol concn. is known by measuring the limiting current value.

Abstract: PROBLEM TO BE SOLVED: To improve the handlability of a cartridge by preventing the inversion of a card. SOLUTION: The plural cards 100 are housed inside the cartridge 400 so as to be in a laminated state in the longitudinal direction. When a weight 407 is placed on the laminated state-card 10, the weight 407 helps the cards 10 to fall. Return preventing mechanism permits the weight 407 to move downward to the lower part of a case and prevents it from returning to the upper part of the case. Thus, even if the cartridge 400 is laterally turned, the weight 407 is not returned to the upper part of the case by return preventing mechanism so that the cards 10 are not scattered and not inverted and, than, the cartridge 400 is easily handled.
