Title: Control device for direct injection spark-ignition type internal combustion engine
Inventor: TOMITA MASAYUKI
IPC: F02D41/14
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To normally and excellently execute stratified stoichiometric combustion by increase/decrease correcting both of the fuel injection amount at an intake air process and the fuel injection amount at a compression process with a feedback corrective coefficient set so as to make an air-fuel ratio become stoichiometric. SOLUTION: When starting an internal combustion engine 1, the internal combustion engine 1 is cranked by a control unit 50 so as to execute fuel injection (direct fuel injection in an intake air process), thereby operating the internal combustion engine 1 by direct injection uniform combustion. It is judged whether an exhaust emission cleaning catalyst 9 is activated or not, and in the case of NO, it is judged whether a shift permitting condition is established or not. In a case where the judgement is YES, stratified stoichiometric combustion for raising exhaust emission temperature is executed by injecting fuel in a combustion chamber in a compression process.  At that time, the fuel injection amount at an intake air process and the compression process is increase/decrease corrected by a feedback corrective coefficient set to make an air-fuel ratio become stoichiometric, thereby ensuring excellent stratified stoichiometric combustion.

Inventor: MIKI KATSUHIKO
IPC: H01L21/304
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To dissolve metal contamination and imperfect appearance at the time of a mirror surface polishing process of a substrate surface or a beveling part, by performing mirror surface polishing in the state that a protective film is formed on a substrate on which an oxide film is eliminated. SOLUTION: After an oxide film which is formed on the surface of a semiconductor substrate by a donor vanishing thermal treatment process (oxygen deposition nucleus forming thermal treatment process) (S11) in an atmosphere containing oxygen is eliminated by an oxide film eliminating process (S12), a protective film is formed on the whole surface by a protective film forming process (S13). The semiconductor substrate on which the protective film is formed is sent to a beveling part mirror surface polishing process (S5A) or a surface mirror surface polishing process (S5B) which are the next processes, and mirror surface polishing is performed.  At this time, metal impurities contained in abrasives are stuck on the substrate and taken in the substrate, or imperfect appearance due to adhesion of the abrasives is generated in the case that the surface of the semiconductor substrate is active. By forming the protective film, generation of metal contamination and imperfect of appearance can be reduced.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of a bright line, and generation of light leak, to increase outgoing light quantity, and to provide equalized surface illumination. SOLUTION: In this surface light source device 1, a reflection sheet 3 is protruded toward a fluorescent lamp 7 over an incidental surface side edge 21 of a guide plate 4, and a light absorbing layer 18 is formed at a tip part on the fluorescent 7 side of the reflection sheet 3. Light H incidental from an incidental side edge 21 of the guide plate 4 is physically shielded by the reflection sheet 3, and light close to the incidental surface side edge 21 of the guide plate 4 is absorbed by the light absorbing layer 18 of the reflection sheet 3.  However, the light absorbing layer 18 is formed in such a way that its light absorbing rate becomes higher as it is more apart from a fluorescent lamp side tip 3a of the reflection sheet 3, so light quantity absorbed by the light absorbing layer 18 of the reflection sheet 3 is reduced compared to conventional devices, thereby more light quantity than in conventional devices is taken into the guide plate 4 through an incidental surface 6.

IPC: G02B6/42
Filed: 1992-09-25
Abstract: PURPOSE:To couple an optical waveguide or optical fiber and a laser diode with a simple construction and practicable optical coupling efficiency and to relieve permissible accuracy at the time of packaging. CONSTITUTION:The end face 2 of an optical fiber 1 is worked to a projecting spherical surface shape and is so disposed that the optical axis of the active layer 4 of the laser diode 3 aligns to the optical axis of the fiber in a position apart from the end face on the optical axis of the optical fiber. A refractive index adjusting material 5 having the refractive index slightly lower than the refractive index of a fiber core and higher than the refractive index of the air is packed between the end face 2 of the fiber and the laser diode 3. The same holds true of the case the optical waveguide formed by working the end face of the optical fiber to the projecting spherical surface is used. The permissible accuracy at the time of packaging is relieved by the refractive index adjusting material 5, by which the assembly is facilitated. Further, the suppression of the reincident reflected light on the laser diode is possible without subjecting the end face of the fiber core to a low reflection treatment. Stable laser oscillation is thus obtd.

Title: Battery charging method
Inventor: KURITA SHINJI
IPC: H01M10/44
Filed: 1990-09-28
Abstract: PURPOSE:To check rise of battery temperature with a simple means at the last stage of battery charging by installing a detection circuit of charging voltage and a control circuit of charging current to detect an increase of battery voltage and controlling the optimum charging current through a control circuit. CONSTITUTION:The battery voltage (DC 6V) of an NiCd battery 1 increases like charging voltage Vo as time t passes. This battery voltage is detected by a detection circuit 31 and the voltage difference >=V of charging voltage V becomes gradually smaller as time passes in the neighborhood of charging voltage V1 (DC 9V). The control circuit 32 of charging current controls the current to an NiCd battery 1 with the use of that voltage difference >=V. The battery is charged nearly in a full charging state without a temperature increase generated at the last stage of charging by performing that current control near time t0 before rise of temperature T. It is thereby possible to check an increase in temperature of the battery generated at the last stage of charging of the battery by a comparatively simple circuit constitution.

Title: Radiation screening
Inventor: MIZUSAWA TAKESHI
IPC: H01L21/66
Filed: 1987-10-14
Abstract: PURPOSE:To enable removal of a part with a low resistance to radiation, by recovering deterioration in radiation with a high temperature voltage-applied burn-in to allow a radiation screening at a high dosage. CONSTITUTION:A voltage is applied to an LSI and a radiation screening is performed with the operation of a pulse at a clock frequency of 100kHz and a power source voltage is measured at a lower limit in the operation of the LSI to remove a troubled part and a part with a large deterioration in characteristic. Then, a burn-in operation is performed for several to 100hr or so with a pulse operation the same as that gamma rays are radiated at a high temperature of 125 deg.C to remove a troubled part and a part with a large deterioration in characteristic. Deterioration in a semiconductor is caused by radiation as a positive fixed charge is generated in an oxide film on the surface of a semiconductor and this positive charge vanishes being bonded to electron injected into the oxide film during the burn-in operation. This enables the recovery of the characteristic of the semiconductor part deteriorated by the radiation screening.
