Title: Method and apparatus for fluidized layer/jet grinding
Inventor: SCHWECHTEN DIETER
IPC: B02C19/06
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To improve a ginding effect of jet grinding by minimizing an eddy loss owing to a speed difference between a jet and a particle of a ground material by a method wherein a gas jet or a steam jet is accelerated together with a part of a material to be ground, introduced into a fluidized ground material layer, collected in a flat cylindrical mixing chamber, and mixed. SOLUTION: A ground material wherein a new charge material via A hopper 2 and an amount adjusting screw conveyor 3, and a coarse particle material are adjustingly mixed with motors 7, 8, is sent to a pressure chamber 11 via a material charge part 1 and a lock chamber 22. The ground material is dispersed with gas or steam introduced from a grinding gas inlet 17 in a mixing chamber 14, and supplied to a fluidized bed type opposed jet type grinder 5 via a jet pipe 15. Pressure release of a particle-containing high pressure jet into the grinder 5 is executed directly in the fluidized bed 4 via a nozzle 16, and a fine particle generated in grinding is discharged from a fine particle outlet 18 of a classifier 19. The jet of an optimum load can improve use of energy of the particle jet in minimum eddy loss by exchange action with the fluidized bed after flowing out from the nozzle.

Title: Non-volatile semiconductor storage
Inventor: SATO YASUO
IPC: H01L21/8247
Filed: 1994-07-19
Abstract: PURPOSE:To reliably rewrite data without causing excessive erasure by setting the threshold voltage of a memory cell when a floating gate is in neutral state to a value between both threshold values when the memory cell is erased and is written. CONSTITUTION:A floating gate memory cell where a floating gate and a control gate are formed is provided on the channel region of a semiconductor substrate. The threshold voltage when the floating gate is in neutral state 'initial' is set to a value between a threshold voltage when the memory cell is in erased state '0' and that when the memory cell is in writing state '1'. For example, the threshold value in the writing state '1' and the erasure state '0' are set to approximately 7V and 2V, respectively, and the threshold value when the floating gate is in the neutral state 'initial' is set to approximately 4V, thus drastically reducing the number of memory cells in excessive erasure state and reliably achieving rewriting.

Title: Semiconductor device
Inventor: YAMAMOTO SEI
IPC: G05F3/30
Filed: 1993-06-30
Abstract: PURPOSE:To accurately discriminate the signal of a sensor, etc., and to make a device compact by forming a signal processing IC and a power IC on the same chip and precisely discriminating the signal of the sensor, etc. CONSTITUTION:The inside of the device consists of a constant voltage circuit 2 composed of a band-gap(B.G.) reference voltage 21, a comparator 3, a waveform shaping circuit 4, etc. The constant voltage circuit 2 is driven by a battery 5 for a vehicle and generates an output 30 determined by a B.G. reference voltage. This output 30 is much smaller than the battery voltage and even if variation of the battery voltage is very large, the output voltage 30 never drops, so that variation in threshold voltage is not caused. Further, the output 30 is connected directly to the threshold voltage input terminal of the comparator 3, so no division resistor is required and the need for trimming for the resistance is eliminated, and, the possibility that a noise due to a short connection is received, is eliminated and an extremely stable threshold voltage is obtained.

Title: Fuel cell catalytic reactor, fuel cell system and carrier
Inventor: OHARA HIROAKI
IPC: C01B3/38
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To properly maintain temperatures in a reactor by providing a catalytic reactor main body having a carrier carrying a CO-oxidation catalyst and a heat exchanging means for cooling or heating the reactor main body and providing a honeycomb structure for the carrier. SOLUTION: This catalytic reactor 14 comprises a catalytic reactor main body 14a having carrier 13 carrying a CO-oxidation catalyst and a cooling part 15 for cooling it. Since the carrier 13 is a honeycomb structure with excellent heat conductivity, the generated heat by an oxidation reaction is immediately conducted to the cooling part 15, the temperatures in the catalytic reactor main body 14a are prevented from excessively rising and the temperatures are properly maintained. Consequently, the efficiency of the CO-oxidation reaction is highly maintained.  Additionally, since the carrier 13 is layered with flat plate materials 11 and 12 contacted each other in a large contact area, the relative position shift of the flat plate materials 11 and 12 is hardly generated even if vibrations are applied and the abrasion of the catalyst due to rubbing the flat plate materials 11 and 12 when mounted on an automobile is hardly generated. Thus, a decrease in an amount of the catalyst can be prevented.

Title: Protection circuit for electronic ballast
Inventor: BOKU JIYUNPOU
IPC: H05B41/24
Filed: 1990-07-18
Abstract: PURPOSE:To protect a ballast by detecting the rise of voltage and stopping an oscillator which supplies high frequency voltage to a fluorescent lamp when the voltage to be supplied to the fluorescent lamp becomes high abnormally. CONSTITUTION:Voltage at the output side (that is an E point) of a secondary coil P2 of an output transformer T2 is converted into a d.c. voltage by a diode Da and supplied to a variable resistor VR. The voltage which is divided by the resistor VR charges a capacitor Cc through a diode Db. When continuous pulses are generated at the E point, the voltage of the resistor Rc turns on the SCR and operates a switch S and the voltage at the H point becomes an earth voltage and thus an oscillation transformer T1 is short-circuited and the oscillation is stopped and the fluorescent lamp is turned off.

Filed: 1993-07-30
Abstract: PURPOSE:To provide a production mthod for a heat-resistant color filter by which a color filter layer having a fine pattern can be formed on a glass substrate with good accuracy. CONSTITUTION:A colored photosensitive resin layer compounded with a pigment is formed on a glass substrate 1 and is exposed and developed to form a pattern. Thus, green, red and blue colored resin pattern layers 2G, 2R, 2B are formed. These colored resin pattern layers are softened by heating, on which a glass powder having low melting point is sprayed to deposit a glass poweder 3'. Then the color resin pattern layer with the glass powder stuck is baked to remove the photosensitive resin in the resin pattern layer to form color filter layer 3G, 3R 3B comprising the colored pigments and the glass having low melting point. By this method, the obtd. pattern has less deformation compared to a pattern formed by a conventional method of forming color filter layer by screen printing, so that a color filter layer having a fine pattern can be formed with good accuracy.
